Abstract
PURPOSE To propose a new optimal strategy for incorporating tumor deposit (TD) into TNM staging. METHODS Totally, 2730 consecutive gastric cancer (GC) patients were included according to the presence and count of TDs between January 2011 and December 2014. Overall survival (OS) was analyzed using Cox regression and propensity score matching (PSM). The relationship between the number of TDs and GC patients' prognosis was analyzed using restricted cubic spline curves and compared with the prognostic value of lymph node metastases (LNMs). Harrell's C-index (C-index) and the Akaike information criterion (AIC) were employed to assess the prognostic performance of different staging systems. RESULTS The positive rate of TD was 9.67% (264/2730). The presence of TD was associated with poorer OS before PSM (hazard ratio (HR): 3.31; 95% confidence interval (CI): 2.84, 3.85) and after PSM (HR: 1.62; 95%CI: 1.31, 2.00). The modified TNM staging, equating one TD to four LNMs, achieved superior prognostic performance, surpassing the 8th edition AJCC TNM staging and other modified systems (C-index: 0.751, AIC: 15954.0). In this system, 12.04% (26/216) of TD-positive patients were upstaged from stage II to stage III. These upstaged patients had worse outcomes than the remaining stage II patients (HR: 10.97; 95% CI: 4.55-26.44), while outcomes were similar to those of original stage III patients (HR:1.08; 95%CI: 0.66, 1.78). CONCLUSION The presence and increased number of TDs were noted to be associated with GC patients' poor prognosis. Integrating TD count with LNMs could enhance the prognostic accuracy of the TNM staging system.

EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2025; 51:109719. [PMID: 40120354 DOI: 10.1016/j.ejso.2025.109719] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2024] [Revised: 01/19/2025] [Accepted: 02/19/2025] [Indexed: 03/25/2025]
Abstract
BACKGROUND In gastric cancer (GC), the significance of the number of tumor deposits (TDs) in prognostic evaluation remains a subject of debate. This study aims to investigate whether TDs can be equated to regional metastatic lymph nodes, potentially improving the accuracy of prognostic assessments in patients with TDs. METHODS A retrospective analysis of clinicopathologic and follow-up data from patients who underwent radical gastrectomy at Yijishan Hospital of Wannan Medical College over a decade, from January 2012 to December 2021, was conducted. Patients were classified into TDs-negative and TDs-positive groups on the basis of the detection of TDs in their postoperative pathology reports. RESULTS The study included 4972 patients, with 575 (11.56 %) identified as having TDs. Among these, 524 TDs-positive patients were matched at a 1:1 ratio with 524 TDs-negative patients. Under the original TNM staging system, the chi-square (χ2) value was 58.234, with a C-index of 0.593. When TDs were classified as regional metastatic lymph nodes, the χ2 value for the modified TNM staging system rose to 72.269, with an improved C-index of 0.609. Nevertheless, the prognosis within the TDs-positive subgroups IIIa, IIIb, and IIIc was still significantly worse than those in the TDs-negative subgroup, even when TDs were reclassified for staging purposes (P < 0.001). CONCLUSION Although treating TDs as regional metastatic lymph nodes can increase the accuracy of disease staging in GC patients, it does not necessarily convey the true prognostic value of TDs.

Abstract
BACKGROUND The mechanism underlying the formation of gastric tumor deposits (TDs) is unclear. We aimed to explore the risk factors for the formation and prognostic value of TDs. METHODS This retrospective analysis included 781 locally advanced gastric cancer (LAGC) patients from four medical institutions in China, from June 2014 to June 2018. The risk factors for TD formation and prognostic value were determined through univariate and multivariate analyses. RESULTS Univariate analysis revealed that TD positivity was closely related to tumor diameter, Borrmann classification, differentiation degree, pT stage, pN stage, pTNM stage, and nerve and vascular invasion (p < 0.05). Multivariate logistic regression revealed that tumor diameter ≥ 5 cm (odds ratio [OR] 1.836, 95% confidence interval [CI] 1.165-2.894, p = 0.009) and vascular invasion (OR 2.152, 95% CI 1.349-3.433, p = 0.001) were independent risk factors for TD positivity. Multivariate Cox analysis revealed that TD positivity (OR 1.533, 95% CI 1.101-2.134, p = 0.011), tumor diameter ≥ 5 cm (OR 1.831, 95% CI 1.319-2.541, p < 0.001), pT4a stage (OR 1.652, 95% CI 1.144-2.386, p = 0.007), and vascular invasion (OR 1.458, 95% CI 1.059-2.008, p = 0.021) were independent risk factors for GC prognosis. The 5-year overall and disease-free survival of the TD-positive group showed significant effects among patients in the pT4a and pN3b stages (p < 0.05). CONCLUSIONS TDs are closely related to tumor diameter and vascular invasion in LAGC patients, and TD positivity is an independent prognostic factor for LAGC patients, especially those at pT4a and pN3b stages.

Abstract
Tumor deposits (TDs) are defined as discontinuous neoplastic masses within the lymphatic drainage pathway of the primary tumor. The poor prognostic implication of these masses have been demonstrated in various cancers. The aim of this study is to investigate the incidence of TDs in our thyroid carcinoma cases, which has not been studied so far to the best of our knowledge, and to determine the prognostic value of their existence. In this retrospective cohort study, 194 thyroid carcinoma cases with cervical lymph node sampling and/or dissection were reevaluated for TDs. The case series consisted of 176 thyroid papillary carcinoma (TPC) and 18 thyroid medullary carcinoma (TMC) patients. TDs were detected in 54 (27.8%) patients. TMC cases (55.6%) had significantly more TDs compared to TPCs (25.0%; P = .006). TDs were more common in women (P = .045), and in multifocal tumors (P = .017). In addition, cases with TDs had larger tumor size (P = .002), more lymphatic invasion (P = .009), extrathyroidal extension (P < .001), and distant metastasis (P < .001). The mean follow-up period of the patients was 120.1 months (range, 4-341 months). Locoregional recurrence detected in 17 patients (8.8%) was more common in TMC (33.3%) than TPC cases (6.3%; P = .002). Distant metastasis was identified in 27 patients (13.9%). Ten-year recurrence free survival (RFS) and overall survival (OS) for all patients were 89.0% and 92.4%, respectively. Mean estimated OS time for TD negative and TD positive cases were: 281.9 (±17.2), 325.6 (±6.2) and 217.6 (±27.4) months, respectively (P = .002). Sex (P = .001), tumor type (P = .002), pT classification of the tumor (P < .001), perineural invasion (P = .002) and TDs (P = .002) were significantly associated with OS. In TPC cases individually, extrathyroidal extension (P = .001) and TDs (P = .002) were significantly correlated with distant metastasis. In multivariate analysis, only tumor size was detected as an independent prognostic marker in TPC cases (P = .005). Our results demonstrate the existence of TDs in thyroid carcinoma cases, and indicate a more aggressive behavior pattern of TDs in these tumors.

Abstract
Background Tumor deposits (TD) was a significant risk factor impacting the prognosis of patients diagnosed with gastric cancer (GC), yet it was not currently incorporated into TNM staging systems. The objective of this research was to develop a predictive model for assessing the prognosis of patients with TD-positive GC. Methods Retrospective analysis was performed on the data of 4,972 patients treated for GC with D2 radical gastrectomy at Wannan Medical College's Yijishan Hospital between January 2012 and December 2021. The patients were categorized based on the number of TD (L1: 1, L2: 2-3, L3: ≥4) and the anatomical location of TD (Q1: single area, Q2: multiple areas). In a 3:1 ratio, patients were randomly assigned to one of two groups: training or validation. Results The study included a total of 575 patients who were divided into the training group (n = 432) and validation group (n = 143). Survival analysis showed that the number and anatomical location of TD had a significant impact on the prognosis of patients with TD-positive GC. Univariate analysis of the training group data revealed that tumor size, T-stage, N-stage, histological grade, number and distribution of TD, neural invasion, and postoperative chemotherapy were associated with prognosis. Multivariate Cox regression analysis identified poor histological grade, T4 stage, N3 stage, number of TD, neural invasion, and postoperative chemotherapy as independent prognostic factors for GC patients with TD. A nomogram was developed using these variables, demonstrating well predictive ability for 1, 3, and 5-year overall survival (OS) in the validation set. The DCA curve shows that the constructed model shows a large positive net gain compared to the eighth edition Tumour, Node, Metastasis (TNM) staging system. Conclusion The prognostic model developed for patients with TD-positive GC has a higher clinical utility compared to the eighth edition of TNM staging.

Abstract
OBJECTIVE The value of tumor deposits (TDs) in the prognosis and staging of gastric cancer (GC) is still under debate. This study aims to evaluate the prognostic value of TDs and the best ways to incorporate TDs in the TNM classification of GC. METHODS Patients (n = 3460) undergoing curative gastrectomy for GC in the West China Hospital from 2005 to 2017 were retrospectively reviewed and divided into two groups according to the TD status (positive vs. negative). Later, clinicopathological features and overall survival (OS) between the two groups were compared. Thereafter, the associations between the presence of TD and other clinicopathological factors were evaluated through logistic regression. In addition, univariate and multivariate Cox regression were conducted for determining prognostic factors. The possibility of selection bias was reduced through conducting the 1:1 propensity score matching (PSM) analysis. The modified classification systems proposed previously that incorporated TDs into the TNM staging system were assessed. RESULTS There were 10.5% of patients (362/3460) diagnosed with TDs. TDs were significantly related to unfavorable factors such as advanced T stage and N stage and independently associated with poor prognosis. The 5-year OS of patients with TDs was significantly lower than that of patients without TDs (31.0% vs. 60.9%, P < 0.001), whereas higher than that of patients with peritoneal metastasis (31.0% vs. 5.0%, P < 0.001). In patients receiving chemotherapy, the 5-year OS of patients with TDs was also significantly lower than that of patients without TDs (42.0% vs. 50.9%, P = 0.026). Moreover, the system incorporating TDs in the TNM classification as metastatic lymph nodes outperformed others. CONCLUSIONS TDs are related to the aggressive characteristics and are an independent prognostic factor for GC. Incorporating TDs in the TNM classification as the metastatic lymph nodes increases the accuracy in predicting prognosis.

Li Y, Li S, Liu L, Zhang LY, Wu D, Xie TY, Wang XX. Incorporation of perigastric tumor deposits into the TNM staging system for primary gastric cancer. World J Gastrointest Oncol 2023; 15:1605-1615. [PMID: 37746641 PMCID: PMC10514718 DOI: 10.4251/wjgo.v15.i9.1605] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Revised: 07/15/2023] [Accepted: 08/02/2023] [Indexed: 09/13/2023] Open
Abstract
BACKGROUND The current prognostic significance of perigastric tumor deposits (TDs) in gastric cancer (GC) remains unclear. AIM To assess the prognostic value of perigastric TDs and put forward a new TNM staging framework involving TDs for primary GC. METHODS This study retrospectively analyzed the pathological data of 6672 patients with GC who underwent gastrectomy or surgery for GC with other diseases from January 1, 2012 to December 31, 2017 at the Chinese PLA General Hospital. According to the presence of perigastric TDs or not, the patients were divided into TD-positive and TD-negative groups by using the method of propensity score matching. The differences between TD-positive and TD-negative patients were analyzed using binary logistic regression modeling. The Kaplan-Meier method was used to plot survival curves. Multivariate Cox regression modeling and the log-rank test were used to analyze the data. RESULTS Perigastric TDs were found to be positive in 339 (5.09%) of the 6672 patients with GC, among whom 237 were men (69.91%) and 102 were women (30.09%) (2.32:1). The median age was 59 years (range, 27 to 78 years). Univariate and multivariate survival analyses indicated that TD-positive GC patients had a poorer prognosis than TD-negative patients (P < 0.05). The 1-, 3-, and 5-year overall survival rates of GC patients with TDs were 68.3%, 19.6%, and 11.2%, respectively, and these were significantly poorer than those without TDs of the same stages. There was significant variation in survival according to TD locations among the GC patients (P < 0.05). A new TNM staging framework for GC was formulated according to TD location. When TDs appear in the gastric body, the original stages T1, T2, and T3 are classified as T4a with the new framework, and the original stages T4a and T4b both are classified as T4b. When TDs appear in the lesser curvature, the previous stages N0, N1, N2, and N3 now both are classified as N3. When TDs appear in the greater curvature or the distant tissue, the patient should be categorized as having M1. With the new GC staging scheme including TDs, the survival curves of patients in the lower grade TNM stage with TDs were closer to those of patients in the higher grade TNM stage without TDs. CONCLUSION TDs are a poor prognostic factor for patients with primary GC. The location of TDs is associated with the prognosis of patients with primary GC. Accordingly, we developed a new TNM staging framework involving TDs that is more appropriate for patients with primary GC.

Tumor Deposit Is an Independent Factor Predicting Early Recurrence and Poor Prognosis in Gastric Cancer. J Gastrointest Surg 2023; 27:1336-1344.

Abstract
BACKGROUND Accurate prognostic estimation is crucial; however, the prognostic value of tumor deposits in gastric cancer remains controversial. This study aimed to investigate their prognostic significance. METHODS Clinicopathological and prognostic data of 1012 gastric cancer patients who underwent R0 or R1 surgery from 2010 to 2017 at the Osaka International Cancer Institute were retrospectively reviewed. RESULTS Overall, 6.3% patients had tumor deposits, which were associated with Borrmann type, surgical procedure, type of gastrectomy, extent of lymphadenectomy, tumor size, histology, pT, pN, pM, pStage, lymphatic invasion, vascular invasion, preoperative chemotherapy, and postoperative chemotherapy. Tumor deposit-positive patients had worse 5-year disease-free survival (32.60% vs. 92.45%) and overall survival (41.22% vs. 89.37%) than tumor deposit-negative patients. Subgroup analysis regarding pStage II-III also showed significant differences between patients with and without tumor deposits for 5-year disease-free survival (34.15% vs. 80.98%) and overall survival (43.17% vs. 75.78%). Multivariable analysis showed that older age, undifferentiated histology, deeper tumor invasion, lymph node metastasis, distant metastasis, and presence of tumor deposits were significantly correlated with early tumor recurrence and shorter survival time; these factors were identified as independent prognostic factors. The 5-year disease-free survival of tumor deposit-positive patients was significantly worse than that of patients in the pStage III group and comparable to that of patients in the pT4, pN3, and pM1 groups. The 5-year overall survival of tumor deposit-positive patients was comparable to that of the pT4, pN3, pM1, and pStage III groups. CONCLUSIONS Tumor deposits are strong and independent predictors of tumor recurrence and poor survival.

Xu R, Zhang Y, Zhao J, Chen K, Wang Z. Prognostic value of tumor deposits in lymph node-negative gastric cancer: A propensity score matching study. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2022; 49:845-852. [PMID: 36543660 DOI: 10.1016/j.ejso.2022.12.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2022] [Revised: 10/05/2022] [Accepted: 12/12/2022] [Indexed: 12/15/2022]
Abstract
BACKGROUND The purpose of this study was to assess the prognostic value of TD in lymph node-negative GC. METHODS A retrospective study was conducted to collect the clinicopathological data from 1224 patients with lymph node-negative GC. According to their TD status, patients were categorized into TD-positive and TD-negative groups. Patients in both groups underwent a 1:1 propensity score matching analysis. Survival analysis was performed by the Kaplan-Meier method, and the differences between survival curves were measured by log-rank test. The cox proportional hazards model was used for univariate and multivariate analyses. RESULTS The TD-negative group had higher 5-year overall survival(OS) rate than TD-positive group(69.4%VS.36.4%,P < 0.05). Further subgroup analysis indicated that patients in the TD-negative group had higher 5-year OS rates than those in the TD-positive group in the T1-2, T3, and T4 subgroups(all with P < 0.05).The OS rates were decreased with the increase of the number of TD.The univariate Cox regression analysis demonstrated that tumor location in antrum, distal gastrectomy, perineural invasion, T4-stage,lymphovascular invasion and the number of TD were all associated with prognosis in patients undergoing curative gastric resection (P < 0.05).The multivariable analysis revealed that the number of TD, perineural invasion, lymphovascular invasion and T4 stage were independently associated with OS. CONCLUSION In lymph node-negative GC, TD is an independent risk factor for prognosis, regardless of T-stage, and patients with ≥3 TD have a worse prognosis.

Prognostic significance of tumor deposits in radically resected gastric cancer: a retrospective study of a cohort of 1915 Chinese individuals. World J Surg Oncol 2022; 20:304.

Abstract
BACKGROUND Tumor deposits (TDs) have been identified as an independent prognostic factor in gastric cancer (GC). However, the associated clinicopathological factors and how to simply and reasonably incorporate TD into the TNM staging system remain undetermined. The aim of the current study was therefore to assess the significance of TD among radically resected GC patients. METHODS We retrospectively reviewed 1915 patients undergoing radical resection between 2007 and 2012. The patients were classified into two groups according to TD status (absent vs. present), and the clinicopathologic characteristics, DFS, and OS were compared. Associations of TD presence with other clinicopathologic factors were evaluated by logistic regression analysis. Univariate and multivariate Cox regression analyses were performed to determine the prognostic factors for DFS and OS in the primary cohort. Propensity score matching (PSM) was performed to reduce the possibility of selection bias according to the presence of TD. External validation of previously proposed modified staging systems incorporating TD was conducted. RESULTS The detection rate of TD was 10.5% (201/1915). The presence of TD was significantly related to unfavorable clinicopathologic variables, including advanced T and N categories. According to the multivariate Cox regression analysis, the presence of TD was identified as an independent prognostic factor for DFS and OS in the primary cohort (both P < 0.001). In the after-PSM cohort, TD presence also significantly shortened DFS and OS. In the external validation, one system that incorporated TD into the pTNM stage had the best performance. CONCLUSIONS The presence of TD was significantly associated with poor survival in radically resected GC patients. The incorporation of TD into the TNM staging system can further improve the predictive capability. A multicenter cohort with a large sample size is needed to determine the appropriate method of incorporation.

An artificial intelligence model to predict survival and chemotherapy benefits for gastric cancer patients after gastrectomy development and validation in international multicenter cohorts. Int J Surg 2022; 105:106889. [PMID: 36084807 DOI: 10.1016/j.ijsu.2022.106889] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Revised: 08/19/2022] [Accepted: 08/28/2022] [Indexed: 11/16/2022]
Abstract
BACKGROUND Gastric cancer (GC) is a major health problem worldwide, with high prevalence and mortality. The present GC staging system provides inadequate prognostic information and does not reflect the chemotherapy benefit of GC. METHODS Two hundred fifty-five patients who underwent surgical resection were enrolled in our study (training cohort = 212, internal validation cohort = 43). Nine clinicopathologic features were obtained to construct an support vector machine (SVM) model. The cohorts from 4 domestic centres and The Cancer Genome Atlas (TCGA) were used for external validation. RESULTS In the training cohort, the AUCs were 0.773 (95% CI 0.708-0.838) for 5-year overall survival (OS) and 0.751 (95% CI 0.683-0.820) for 5-year disease-free survival (DFS); in the domestic validation cohort, the AUCs were 0.852 (95% CI 0.810-0.894) and 0.837 (95% CI 0.792-0.882), respectively. The model performed better than the TNM staging system according to the receiver operator characteristic(ROC) curve. GC patients were significantly divided into low, moderate and high risk based on the SVM. High-risk TNM stage Ⅱ and Ⅲ patients were more likely to benefit from adjuvant chemotherapy than low-risk patients. CONCLUSIONS The SVM-based model may be used to predict OS and DFS in GC patients and the benefit of adjuvant chemotherapy in TNM stage Ⅱ and Ⅲ GC patients.

Abstract
BACKGROUND Total omentectomy is often performed with gastrectomy as radical surgery for gastric cancer (GC) patients. However, it remains controversial whether GC patients can benefit from omentectomy. The aim of this study was to analyze the incidence and clinical significance of tumor deposits (TDs) in different anatomical subregions of perigastric omentum in GC patients undergoing gastrectomy with total omentectomy. METHODS From October 2011 to December 2013, 1253 patients who underwent gastrectomy with total omentectomy for GC were retrospective reviewed. The TDs in different anatomical subregions of perigastric omentum were examined. RESULTS Of 1253 patients, TDs positivity was 11.2%. Tumor deposits in the omentum of greater curvature and in the omentum of lesser curvature were associated with lymphovascular invasion, perineural invasion, advanced tumor node metastasis stages, and unfavorable survival. Besides, TDs in the proximal omentum of greater curvature and in the omentum of lesser curvature correlated with older patients and larger tumors. Kaplan-Meier curves showed that patients with TDs had worser overall survival (OS) than those without, regardless of TD positions. Patients with TDs in the omentum of greater curvature had the worst prognosis, followed by patients with TDs in the omentum of lesser curvature and patients with no TDs. Tumor deposits in the proximal omentum of greater curvature was an independent prognostic factor for OS. Moreover, only patients classified as pT4 had TDs in the distal omentum of greater curvature. CONCLUSIONS Patients with TDs in the omentum of greater curvature had the worst prognosis, followed by patients with TDs in the omentum of lesser curvature and patients with no TDs. In addition, partial omentectomy might be practicable for gastric cancer patients classified as T3 or shallower tumors.

Abstract
OBJECTIVES The TNM classification is the main tool for lymph node (LN) staging in gastric cancer (GC). However, alternative LN staging systems have been proposed, and the role of features other than the number of metastatic LNs is being investigated. Our aim is to discuss the main challenges of LN assessment in GC. METHODS Comprehensive review of the literature on alternative LN staging systems, examined LNs, sentinel LN (SLN) biopsy, LN micrometastases (LNMIs), extracapsular extension (ECE), and tumor deposits (TDs) in GC. RESULTS Many controversies exist regarding LN assessment in GC. The TNM classification shows excellent prognostic performance, but alternative prognostic methods such as the LN ratio or log odds of positive LNs have demonstrated to be better than the TNM system in terms of prognostic accuracy. The value of SLN biopsy and LNMIs in GC is still unclear, and several challenges concerning their clinical impact and pathologic analysis must be overcome before their introduction in clinical practice. Most authors have identified ECE and TDs as independent prognostic factors for survival in GC. CONCLUSIONS Further studies should be performed to evaluate the impact of these features on the TNM classification and patient outcomes, as well as to standardize alternative LN staging systems.

Clinicopathological factors associated with the presence of tumor deposits in resected gastric cancer patients. Heliyon 2021; 7:e07185. [PMID: 34141939 PMCID: PMC8188374 DOI: 10.1016/j.heliyon.2021.e07185] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2021] [Revised: 04/29/2021] [Accepted: 05/27/2021] [Indexed: 11/20/2022] Open
Abstract
Purpose The role of tumor deposits (TDs) in the staging of gastric cancer is currently debatable. TDs are defined as tumoral nodules in perigastric adipose tissue with no evidence of lymphatic, vascular, or neural structures. Clinicopathological factors related to the presence of TDs are not well defined. This study aimed to identify the clinicopathological factors associated with the presence of TDs in resected gastric cancer patients. Materials and methods This prospective study included patients diagnosed with gastric cancer and treated with D2 radical gastrectomy from January 2019 to January 2020. Univariate and multivariate analyses were performed to determine the factors related to the presence of TDs. Results A total of 111 patients were eligible and TDs were present in 31 of them (28%). In the univariate analysis, male gender (p = 0.027), tumor size ≥ 5cm (p = ≤0.001), serosa and adjacent organs invasion (pT4a and pT4b) (p = ≤0.001), ≥16 metastatic lymph nodes (pN3b) (p = ≤0.001), and TNM stage III tumors (p = ≤0.001) were significantly associated with the presence of TDs. The multivariate analysis showed that a tumors size ≥5 cm (OR = 3.69, 95% CI: 1.17-11.6), serosa and adjacent organs invasion (pT4a and pT4b) (OR = 3.78, 95% CI: 1.31-10.86) and ≥16 metastatic lymph nodes (pN3b) (OR = 3.21, 95%CI:1.06-9.7) were independent risk factors for the presence of TDs. Conclusions Larger tumors (tumor size ≥ 5cm), serosa and adjacent organs invasion (pT4 and pT4b), and ≥16 metastatic lymph nodes (pN3b) were independent risk factors for the presence of TDs.

Abstract
Background A tumor deposit (TD) is a phenomenon that has not been well studied in head and neck squamous cell carcinoma (HNSCC) but might have prognostic significance. The present study was conducted to explore the presence and the prognostic significance of TDs in patients with HNSCCs. Methods Six hundred forty-two pathologically confirmed HNSCC patients with neck dissection samples were enrolled in this retrospective study. Patients were followed up and evaluated every 3 months in the first 3 years after surgery, and every 6 months thereafter by physical examination and computed tomography (CT)/magnetic resonance imaging (MRI) scans. The five-year overall survival (OS), disease-specific survival (DSS), and recurrence-free survival (RFS) were compared in the TD and non-TD groups using multivariable analyses and propensity score matching (PSM) methodology (1:1). Results The 5-year OS, DSS, and RFS rate of all patients was 77.3%, 80.6%, and 71.9%, respectively. In the multivariable analyses, poorer rates of OS (HR =2.345, P<0.001), DSS (HR =2.818, P<0.001), and RFS (HR =2.536, P<0.001) were observed in the TD versus the non-TD group. In the PSM cohort, eighty-one patients who had TDs were paired with 70 patients without TDs. Significantly diminished rates of DSS (P=0.040) and RFS (P=0.004) were found in the TD versus the non-TD group. Conclusions In response to sparse reports regarding TDs in HNSCCs, the present study proposes the TD as an independent poor prognostic factor meriting further research because of its association with diminished OS, DSS, and RFS rates.

Abstract
Background The relationship between gastric bare area adipose tissues invasion (GBAI) confirmed pathologically and the prognosis of gastric cancer (GC) patients is undefined. Till present, there has not been literature investigating this phenomenon. Here, we aimed at analyzing the implication of GBAI in GC. Methods The data of 1822 patients who underwent radical surgery between January 2000 and December 2013 at the Sun Yat-sen University Cancer Center were retrieved. Pathologically, tumor deposits (TDs) located > 5 mm from the leading edge of the primary tumor and the lymph nodes (LNs) station number 1, 2, 7, and 9 were considered GBAI. Kaplan-Meier method, log-rank test, and Cox’s proportional hazards model were employed to analyze. Results Two hundred and five (11.3%) patients were pathologically diagnosed with GBAI, which was more commonly found in proximal or linitis lastica than distal GC (P < 0.001). There was significant difference in 5-year survival between patients with and without GBAI for stages IIB, IIIA, IIIB, and IIIC, respectively (P < 0.009 for IIB, IIIA, and IIIB; P = 0.021 for IIIC). Among the 205 GBAI patients, 61 had detailed radiological follow-up data in which 26 (34.7%) were found to have retroperitoneal infiltration, 27 (36.0%) had peritoneal metastasis, 10 (13.3%) had hematogenous metastasis, 16 (21.3%) had lymphatic metastasis, and 16 (21.3%) had others. Conclusions GBAI was identified as a predictor of unfavorable prognosis for GC and was more commonly found in the proximal or linitis plastica of the stomach than in distal stomach. Retroperitoneal infiltration was one of the most commonly identified metastatic route for GC associated with GBAI after radical surgery.

Abstract
BACKGROUND Gastric cancer (GC) treatment is largely determined by tumor stage. Despite improvements in the mode of treatment of various types of advanced disease, staging is still evolving. The role of tumor deposits (TDs) in staging remains debated. The purpose of this research is to investigate the relationship between TDs and prognosis in GC. METHODS A total of 3098 patients were considered eligible for prognostic analysis (2706 patients in the TDs-negative group and 392 patients in the TDs-positive group). A one-to-one propensity score-matching analysis was performed using a logistic regression mode and the following covariates: age, gender, tumor location, size, differentiation, perineural invasion, lymphovascular invasion, pTNM stage, type of gastrectomy, and the number of lymph nodes retrieved between TDs-negative and TDs-positive group, then 323 patients in each group were analyzed. Univariate and multivariate analyses of prognostic factors were conducted accordingly. The predictive ability of different staging system incorporating TDs was evaluated. RESULTS TDs were present in 14.5% cases and almost all of the patients (99%) suffered from advanced GC. Multivariate analysis showed that pN stage, chemotherapy, and TDs were the independent prognostic factors. The TDs-positive group showed a lower rate of 5-year disease-free survival compared with the TDs-negative group in all patients, stage II, and stage III patients (p = 0.001, 0.029, and 0.003, respectively). The 5-year disease-free survival for patients with TDs and without TDs was 27.6% and 34.4%, respectively. CONCLUSIONS Our research shows that TDs are closely associated with prognosis in GC. TDs should be incorporated into the TNM staging system, which could then accurately improve the staging reliability and prognostic assessment.

Abstract
Accurate categorization of invasive depth and lymph node metastasis or optimization of TNM categories is fundamentally critical for prognostic assessment and decision making regarding subsequent therapies after surgery for gastric cancer. Improving the precision of the TNM staging is the ongoing goal. The evolution of the staging system indicates that there is no "ideal staging". Every update has criticized the lack of a standard approach for the stages to date. T staging depends on the accurate determination of the depth of infiltration based on pathological continuous sections. N staging is susceptible to the influence of lymph node detection, and insufficient lymph node detection can lead to N staging migration. M staging is required to improve the detection rate of peritoneal positive free cancer cells to determine the high risk factors of peritoneal metastasis. At present, the quality of standardized pathological diagnosis of gastric cancer requires improvement. Based on a review of the literature and experience from multiple gastric cancer centers, we present a new development in TNM staging and a way to improve clinical and pathological quality control of gastric cancer.

Abstract
BACKGROUND The optimal number of examined lymph nodes (ELNs) and the prognostic value of different nodal staging systems remain unclear in the context of N3b gastric cancer. AIM To evaluate the optimal number of ELNs and compare the predictive ability of the ELN number, LN ratio (LNR), and log odds of metastatic LNs (LODDS) for overall survival (OS) in patients with resected stage N3b gastric adenocarcinoma in an international database. METHODS A total of 868 patients diagnosed between 2004 and 2015 in the Surveillance, Epidemiology, and End Results (SEER) database (training cohort) and 144 patients diagnosed between 2011 and 2016 at the Liaoning Cancer Hospital (validation cohort) were identified. Cutoff values were established with X-tile. The 5-year OS rates were compared using Kaplan-Meier curves. Multivariate analysis was conducted with a Cox regression model. The Harrell's concordance index and Akaike's information criterion were used to compare the predictive accuracy of different nodal staging systems. RESULTS The ELN number, LNR, and LODDS were independent prognostic factors for both the training and validation cohorts in the multivariate analysis. Patient with ≤26 ELNs, LNR of more than 0.9, and LODDS of more than 1.0 were associated with decrease OS. The LNR and LODDS had similar discriminatory ability for OS and performed better than the ELN number in the Eastern and Western populations. CONCLUSION The optimal number of ELN may be 27 or more because LNs retrieved ≤26 was an independent risk factor for the prognosis. The prognostic prediction efficacy of LNR and LODDS was similar and better than that of ELN. Thus, LNR and LODDS could both serve as valid tools to predict OS for stage N3b patients.

Abstract
BACKGROUND Gastric cancer (GC) treatment is determined by accurate tumor staging. The value of tumor deposit (TD) in prognostic prediction staging system is not yet determined. METHODS We retrospectively analyzed clinical information on GC patients who underwent gastrectomy at the Department of General Surgery of the Chinese PLA General Hospital from July 2014 to June 2016. Propensity score matching (PSM) was performed to reduce the possibility of selection bias according to the presence of TD. RESULTS Of the 1034 GC patients, 240 (23.21%) presented with TD, which was associated with younger age and larger tumor size (all P < .05). TD-positive patients had a worse survival than TD-negative patients before (P < .001) and after (P = .017) matching. Multivariable analysis showed that mortality risk of patients with TD increased by 58%, 62%, 37%, and 40% in the crude (HR = 1.58, 95% CI 1.32-1.89, P < .001), adjusted I (HR = 1.62, 95% CI 1.35-1.94, P < .001), adjusted II (HR = 1.37, 95% CI 1.13-1.66, P = .001), and adjusted III (HR = 1.40, 95% CI 1.16-1.68, P < .001) models before matching. Similarly, in the PSM cohort patients with TD had worse prognosis in the crude (HR = 1.32, 95% CI 1.07-1.63, P = .011), adjusted I (HR = 1.35, 95% CI 1.09-1.67, P = .005), adjusted II (HR = 1.26, 95% CI 1.00-1.58, P = .049), and adjusted III (HR = 1.33, 95% CI 1.07-1.65, P = .010) models. TD had a similar value range between N1 and N2 stages among different models. CONCLUSIONS Among GC patients, TD is associated with survival and may have a role in the staging of patients.

Abstract
Background The prognostic value of tumor deposit (TD) in gastric cancer is controversial. This study aims to investigate the prognostic value of TD. Methods The consecutive patients diagnosed with gastric cancer from October 2007 to October 2012 were selected. The patients were divided by whether they suffered TD into two groups. The basic data were comparable between the two groups after propensity score matching (PSM), then survival analysis [overall survival (OS) and cancer-specific survival (CSS)] was applied in two groups. After that, all the patients were divided by pN staging and survival analysis were applied in each subgroup. At last, all patients were divided into TD group, pN1 stage group, pN2 stage group, pN3a, and pN3b stage group, OS and CSS were compared between them. Multivariable competing risk analyses tested association of TD with OS and CSS, before and after PSM. Results Eight hundred and three patients were concluded. After PSM, 137 patients with TD and 274 patients without TD were selected, the 5-year OS and CSS rates of patients with TD were significantly worse than patients without TD (OS: 19.7% vs. 42.0%, P<0.001; CSS: 22.6% vs. 45.6%, P<0.001). In all patients' survival analysis, the 5-year OS and CSS rates of TD group were comparable with pN3a group (OS: 19.7% vs. 25.3%, P=0.221, CSS: 22.6% vs. 30.1%, P=0.092) and pN3b group (OS: 19.7% vs. 19.6% P=0.349, CSS: 22.6% vs. 23.5%, P=0.452). Meanwhile, on multivariable cox regression analyses, the presence of TD significantly reduces the OS and CSS of patients in gastric cancer. Conclusions TD has a marked impact on the prognosis of gastric cancer. Even patients with TD had the same prognosis with pN3 stage.

Abstract
BACKGROUND Extranodal metastasis is an isolated tumor nodule without a residual lymph node structure and has been reported as a poor prognostic factor in gastric cancer. The aim of this study is to assess the prognostic value of extranodal metastasis, especially from the viewpoint of its anatomical distribution. METHODS A total of 139 consecutive gastric cancer patients who underwent curative surgery with lymph node metastasis between 2008 and 2009 were included. Clinicopathological features and patient survival outcomes were retrospectively assessed. Patients with extranodal metastasis were subdivided into two groups: perigastric extranodal metastasis, located near the perigastric area (#1-#7 according to the Japanese classification of gastric carcinoma 15th edition), and extra-perigastric extranodal metastasis, located alongside the major vessels (#8-#12). RESULTS Extranodal metastasis was found in 51 patients (37%), and it was more frequent in those with bulky, ≥pT3, and pStage III tumors. All patients with extra-perigastric extranodal metastasis had recurrence, resulting in a 0% 5-year overall survival rate, which was significantly worse than that of patients with perigastric extranodal metastasis (59%), or those without extranodal metastasis (84%; P < 0.001). Multivariable analysis identified the presence of extra-perigastric extranodal metastasis as an independent poor prognostic factor. CONCLUSIONS Extranodal metastasis, especially extra-perigastric extranodal metastasis, was a pivotal poor prognostic factor in node-positive gastric cancer. Recognizing extra-perigastric extranodal metastasis would help provide optimal therapeutic options to these high-risk patients.

Clin Oncol (R Coll Radiol) 2019; 32:110-120. [PMID: 31570246 DOI: 10.1016/j.clon.2019.09.047] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2019] [Revised: 07/24/2019] [Accepted: 08/09/2019] [Indexed: 01/18/2023]
Abstract
AIMS The survival benefit of radiation therapy in gastric cancer patients who underwent curative resection remains contentious. MATERIALS AND METHODS Gastric cancer patients who underwent curative resection followed by adjuvant chemotherapy or chemoradiation therapy (CRT) between 2004 and 2014 were identified from the National Cancer Database. Survival analyses were carried out with the Kaplan-Meier method and the Cox regression model. RESULTS In total, 4347 patients were included in this study. Of these patients, 1185 patients received postoperative chemotherapy alone and 3162 patients received postoperative CRT. For all patients included in the analysis, patients who received CRT had significantly better overall survival than those who received chemotherapy alone (5-year overall survival: 54.8% versus 46.8%, P < 0.001). The survival benefit primarily occurred in patients with stage II (5-year overall survival: 58.7% versus 53.8%, P = 0.03), stage III (42.5% versus 30.3%, P < 0.001) and lymph node-positive (5-year overall survival: 52.2% versus 41.9%, P = 0.03) gastric cancer. Multivariable analysis confirmed the improvement in overall survival in patients who received postoperative CRT (hazard ratio = 0.78; 95% confidence interval, 0.661-0.926; P < 0.001) was independent of all known prognostic factors. For lymph node-positive patients with lymphovascular invasion (LVI), postoperative CRT significantly improved overall survival compared with chemotherapy alone (5-year overall survival: 49.0% versus 39.4%, P = 0.001). However, there was no survival difference between CRT and chemotherapy alone if lymph node-positive patients had no LVI (5-year overall survival: 54.5% versus 52.7%, P = 0.55). CONCLUSION The current study suggests that postoperative CRT provides a survival benefit in gastric cancer patients with concurrent lymph node-positive and LVI-positive disease. A randomised clinical trial may further evaluate the benefit of adjuvant CRT in this subgroup.

Abstract
Background For patients with locally advanced gastric cancer (LAGC) after D2 gastrectomy, the survival benefits of receiving adjuvant chemoradiotherapy versus adjuvant chemotherapy are unclear. This study aimed to compare the 5- and 7-year overall survival (OS) in the two groups and to identify which patients can benefit more from adjuvant chemoradiotherapy. Methods Retrospective data were collected from January 2009 to December 2014. The 5- and 7-year OS and disease-free survival (DFS) were compared between the two groups using the Chi-square test. The association of OS with prognostic factors was identified using the Cox’s proportional hazard model, which was then adjusted for survival coparison using propensity score-matching (PSM) analysis. The association of OS with each clinical/demographic factor was compared between the two groups using the Kaplan–Meier analysis. Results A total of 415 eligible patients were identified (135 adjuvant chemoradiotherapy, 280 adjuvant chemotherapy). Significant 5- and 7-year OS and DFS benefits were found in the adjuvant chemoradiotherapy group versus chemotherapy group. Multivariate analysis showed that age, TNM stage, lymph node (LN) ratio, tumor deposits, and total/subtotal gastrectomy were independent prognostic factors. When the PSM analysis was adjusting by these factors, 135 patients were matched with an improved survival benefit from adjuvant chemoradiotherapy. Patients in the adjuvant chemoradiotherapy group had a lower locoregional relapse. Subset analysis also identified significant OS benefits of adjuvant chemoradiotherapy in patients with LN ratio <50%, pIIIA, and pIIIB stage disease, while OS benefits were not observed in patients with tumor deposits, pN3b classification, or pIIIC stage disease. Conclusion Adjuvant chemoradiotherapy was shown to be superior in improving the OS in a certain population of patients compared with adjuvant chemotherapy. This finding may help to better guide the individualized treatments of patients with stage III LAGC after D2 gastrectomy.

Abstract
BACKGROUND Extranodal tumor deposits have been reported to be associated with a poor prognosis in many malignancies and are also included in the tumor, node, and metastasis staging system for colorectal cancer. METHODS We reviewed retrospectively a total of 2,344 gastric cancer patients who underwent gastrectomy with curative intent at the Tianjin Medical University Cancer Institute and Hospital (Hexi District, Tianjin, China) and the First Affiliated Hospital of Hainan Medical University (Longhua District, Haikou, China). Patients were categorized into 2 groups based on extranodal tumor deposit status: a positive group, including those with extranodal tumor deposits, and a negative group composed of those with no extranodal tumor deposits. Clinicopathologic factors were correlated with extranodal tumor deposits, and their individual prognoses were analyzed. In addition, a pathologically modified node classification system was proposed by incorporating the extranodal tumor deposit status into the 8th ed of the N staging system. The superiority of prognostic prediction between the modified node classification and node stage was compared. RESULTS A total of 645 (27.5%) patients had extranodal tumor deposits. The presence of extranodal tumor deposits was associated with a larger tumor size, Borrmann type III and IV, a deeper depth of invasion, and an advanced node stage. In the multivariate analysis, extranodal tumor deposits were an independent prognostic factor for gastric cancer patients after curative resection. Gastric cancer patients with extranodal tumor deposits demonstrated a lesser 5-year overall survival than those with no extranodal tumor deposits (31.9% vs 61.4%, P < .001). With the strata analysis, statistically significant prognostic differences between the two groups were only observed in patients at the N0-N2 stage. The modified node classification was found to be more appropriate for predicting the overall survival of gastric cancer patients after curative resection than node stage, and the -2 log likelihood of the modified node classification (16,042.890) was smaller than the value of node stage (16,150.811). CONCLUSION Extranodal tumor deposits in gastric cancer patients indicate aggressive characteristics and a poorer prognosis of gastric cancer. We maintain that extranodal tumor deposits should be incorporated into the N staging system to enhance the accuracy of the prognostic prediction of patients with gastric cancer.

Abstract
AIMS Tumour deposits (TDs) are clusters of cancer cells in the soft tissue that are discontinuous from the primary tumour. In this review we are exploring their relevance for prognosis in patients with gastric cancer. METHODS AND RESULTS A literature search was performed to identify studies providing data on TDs and prognosis in gastric cancer patients. Eight papers were included in the meta-analysis, which was carried out in terms of risk ratios (RR) and hazard ratios (HR) with 95% confidence interval (95% CI). Of 7445 patients, 1551 had TDs (20.9%). TDs were associated with a decreased overall survival (OS) in univariate (HR = 2.82, 95% CI = 1.9-4.3) and multivariate analyses (HR = 1.65, 95% CI = 1.3-2.1). TDs were also associated with known prognostic factors such as synchronous metastatic disease (RR = 9.5), invasion depth (RR = 1.8), lymph node metastasis (RR = 1.7), lymphatic invasion (RR = 1.7), vascular invasion (RR = 2.6) and poor differentiation (RR = 1.2). CONCLUSIONS We found a strong indication that TDs are independent predictors of prognosis in patients with gastric cancer; hence, TDs should be included in the staging of gastric cancers.

Abstract
Tumor deposits (TD) are irregular discrete tumor masses in adipose tissue, discontinuous from the primary tumor, that are described in various cancers. The incidence and/or prognostic value of TD in breast carcinomas have not been studied so far. We reevaluated 145 breast cancer patients, diagnosed and treated between 2001 and 2006 at our institution for the presence and incidence of TD. Histologic type, grade, size of the primary tumor, estrogen receptor, progesterone receptor, human epidermal growth factor receptor-2 status of the tumor, and presence of peritumoral lymphovascular invasion were included in the data. TD were detected in 42 cases (29.0%). The mean age of the patients was 52.2 years (27-82). Most patients (79.3%) had either invasive carcinoma of no special type (NST) or invasive lobular carcinoma, and most tumors (86.9%) were either grade 2 or 3. After excluding TD from the number of metastatic lymph nodes, the pN status of 9 patients changed. Univariate analysis of 110 patients with follow-up information revealed that the new pN status (p = 0.036), presence of local recurrence (p = 0.016) and TD (p = 0.003) were significantly correlated with distant metastases. The median follow-up of the patients was 84 months (5-161), 10-year disease-free survival and overall survival were 67.2% and 73.7%, respectively. In multivariate analysis, presence of TD remained independently associated with distant metastasis (p = 0.002). The probability of distant metastasis was 3.3 times higher in patients with TD. These results emphasize that TD are present in breast cancer patients, and that their presence should warn the clinician in terms of possible distant metastasis. Therefore, presence of TD, the evaluation of which is neither time consuming nor require sophisticated methods, should be included in pathology reports.

Abstract
Background In gastric cancer, various surveillance strategies are suggested in international guidelines. The current study is intended to evaluate the current strategies and provide more personalized proposals for personalized cancer medicine. Materials and Methods In the aggregate, 9191 patients with gastric cancer after gastrectomy from 1998 to 2009 were selected from the Surveillance, Epidemiology, and End Results database. Disease-specific survival was analyzed by Kaplan-Meier method and the log-rank test. Cox proportional hazards regression analyses were used to confirm the independent prognostic factors. As well, hazard ratio (HR) curves were used to compare the risk of death over time. Conditional survival (CS) was applied to dynamically assess the prognosis after each follow-up. Results Comparisons from HR curves on different stages showed that earlier stages had distinctly lower HR than advanced stages. The curve of stage IIA was flat and more likely the same as that of stage I while that of stage IIB is like that of stage III with an obvious peak. After estimating CS at intervals of three months, six months, and 12 months in different periods, stages I and IIA had high levels of CS all along, while there were visible differences among CS levels of stages IIB and III. Conclusions The frequency of follow-up for early stages, like stages I and IIA, could be every six months or longer in the first three years and annually thereafter. And those with unfavorable conditions, such as stages IIB and III, could be followed up much more frequently and sufficiently than usual.

Abstract
Background Both surgical TNM (sTNM) and pathological TNM (pTNM) staging are important clinicopathologic indexes of gastric cancer (GC). However, surgeons and pathologists might assess tumor depth differently in the same patient. To investigate the prognostic significance of sTNM status in patients with radically resected stage pT3-pT4b GC, we examined the relationship between sTNM and pTNM. Methods Clinicopathologic and survival data of 1289 patients with stage pT3-pT4b GC were studied retrospectively, in the aftermath of radical surgery. Results The unconformity for assessing tumor invasion depth were frequently exhibited between sT and pT staging. Comparison of 5-year OS among them, no significant differences were observed (pT3/sT3 vs pT3/sT4a, p=0.962; pT4a/sT4b vs pT4b/sT4b, p=0.508). Also, pT3/sT4b, pT4a/sT3 and pT4a/sT4a were homogeneity in prognosis. We proposed a revised pT stage in which surgical macroscopic T4b (sT4b) was incorporated into the pT stage, namely, patients in the pT3 stage with sT4b cancers were reclassified as being in the r-pT4a stage; patients in the pT4a stage with sT4b cancers were reclassified as being in the r-pT4b stage. In two-step multivariate analysis, revised pT stage proved more suitable for determining prognosis, surpassing both UICC/AJCC pT stage and sT stage as an independent prognostic index. Conclusions Surgical T stage is a significant and independent prognostic index of overall survival (OS) in patients with radically resected advanced GC. Patients in the pT3/4a stage with sT4b cancers, are potentially underestimated, and should be considered higher stage in terms of prognostic.

Beyond T, N and M: The impact of tumor deposits on the staging and treatment of colorectal and gastric carcinoma. Surg Oncol 2018; 27:129-137.

Abstract
This review aims to describe the results of the most recent studies on the prognostic value of TDs and highlight the impact of TDs on the staging and treatment of colorectal and gastric carcinoma. For colorectal carcinoma TDs have an adverse prognostic effect that is at least similar to that of positive regional lymph nodes. However, support is growing in favor of including of TDs in the M category, rather than the N or T categories of the TNM classification. Moreover, TDs seem to have an adverse effect on outcomes not only in patients without lymph node involvement but also in patients with nodal involvement. Although the prognostic impact of TDs in gastric cancer appears to be undeniable, the actual prognostic determinants of TDs, particularly in relation to the number, size and histological types, remain to be established. Although the 7th and 8th Edition of the TNM classification of colorectal and gastric carcinoma includes TDs in the N category, no current procedures or methods to assess preoperative or intraoperative N-status allow TD detection. After neoadjuvant treatment for advanced rectal carcinoma, the presence of TDs may indicate incomplete eradication of the main tumor and not discontinuous tumor foci. TDs have an undeniable prognostic impact but no algorithm of staging and strategy of treatment has been conformed to this prognostic factor to overcome the classical T,N, and M prognostic categories. Staging and treatment of colorectal and gastric cancers should be reconsidered in light of the emerging prognostic value of TDs.

Abstract
BACKGROUND Tumor deposits (TDs) are now observed in esophageal cancer (EC), but the role of TDs is seldom elucidated. This study aimed to research the prognostic significance and the role of TDs in EC. The patients with primary EC, who had undergone curative esophagectomy in West China Hospital from May 2005 to May 2011 were retrospectively enrolled. METHODS The prognosis and clinicopathological traits were compared between tumor deposits positive (TDP) and tumor deposits negative (TDN) groups in all patients and TNM 0-IV stages respectively. RESULTS In our study, 1,044 patients were enrolled, with 948 (90.8%) in TDN group and 96 (9.2%) in TDP group. TDP group had significantly more advanced EC and worse prognosis (all P<0.001) than TDN group in all patients, TNM II stage and TNM III stage. The prognosis of TDP group in TNM II stage was significantly worse than TDN patients in TNM III stage (P<0.001), and the worst prognosis was always found in patients with at least one TD regardless of the number of metastatic lymph node is. CONCLUSIONS Patients in TDP subgroup had more advanced EC and worse prognosis than those in TDN subgroup. It might be more reasonable to be regarded as an indicator of stage migration in EC.

Abstract
BACKGROUND The presence and the prognostic significance of perigastric tumor deposits (TDs) in primary gastric cancer have not been extensively studied. The aim of this study was to evaluate the prognostic significance perigastric TDs in primary gastric cancer. METHODS From 2005 to 2010, 1250 patients underwent R0 gastrectomy at the Department of Gastric Surgery, Fujian Medical University Union Hospital, Fuzhou, China. Out of 1250 patients, 132 patients with perigastric TDs were identified. Additionally, 132 patients with staged matched gastric cancer without tumor deposits were selected as a control group. RESULTS Perigastric TDs were observed in 132 (10.5%) of the 1250 patients with gastric cancer who underwent R0 gastrectomy. There were 94 males (71.21%) and 38 females (28.79%) (2.47:1). The mean age was 57.21 years. Clinicopathologic characteristics between the two groups matched well. There was a significant difference in the overall survival of those with and without TDs by univariate (p<0.05) and multivariate (p < 0.05) survival analysis. The 1-, 3-and 5-year overall survival rates of patients with TDswere69.6%, 39.3%, and 24.2%, respectively, and were significantly poorer than those of the staged matched control group. There was no correlation between the number of TDs and patient survival in patients with gastric cancer (p>0.05); however, when comparing each pT tumor group with the perigastric TD group, the stage T4 survival rate was very similar to that observed in patients with TDs. CONCLUSIONS Perigastric TDs are an independent predictive prognostic factor for gastric cancer and may be appropriately considered a form of serosal invasion. We suggest that TDs should be included in TNM staging system for better outcomes.

Prognostic significance and the role in TNM stage of extranodal metastasis within regional lymph nodes station in gastric carcinoma. Oncotarget 2016; 7:67047-67060. [PMID: 27563811 PMCID: PMC5341856 DOI: 10.18632/oncotarget.11478] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2016] [Accepted: 08/10/2016] [Indexed: 02/05/2023] Open
Abstract
The role of extranodal metastasis (ENM) in TNM stage in gastric carcinoma (GC) is controversial. This study was aimed to make a detailed investigation of the prognostic significance and the role in TNM stage of ENM in GC. The patients with primary GC, who underwent gastrectomy with curative intention in West China Hospital from January 2005 to December 2011, were retrospectively enrolled. The prognosis and clinicopathological traits were compared between ENM positive (ENMP) and negative (ENMN) groups in all patients, TNM I-II, III and IV stages, respectively. The significance of the number and the role in TNM stage of ENM were also assessed. In our study, 1457 patients were enrolled, with 1324 (90.9%) in ENMN group and 133 (9.1%) in ENMP group. ENMP group had significantly more advanced GC and worse prognosis (all p<0.05) than ENMN group in all patients, TNM I-II stages and TNM III stage. ENM>2 subgroup had remarkably larger tumor size (p=0.002) and more advanced N stage (p=0.016) than ENM=1-2 subgroup. The number of ENM was an independent prognostic factor in ENMP group (p=0.029). The prognosis of ENM>2 in TNM I-III stages was significantly worse than ENMN patients in TNM III stage. The C-index of TNM stage plus the number of ENM was significantly higher than that of current TNM stage alone (p=0.005). In conclusion, the patients in ENMP subgroup had more advanced GC and worse prognosis than those in ENMN subgroup. It might be more reasonable to categorize ENM>2 into TNM IV stage.

Abstract
BACKGROUND Macroscopic serosal classification (MSC) is an important clinicopathologic index of gastric cancer (GC). To investigate the prognostic significance of MSC status in patients with radically resected stage pT3-pT4b GC, we examined the relationship between MSC type and pT stage. METHODS Clinicopathologic and survival data of 1613 patients with stage pT3-pT4b GC were studied retrospectively, in the aftermath of radical surgery. RESULTS MSC types, including reactive, nodular, tendonoid, and color-diffused type, correlated significantly with overall survival (OS) in this cohort, but prognosis was similar for all stages of color-diffused type GC. We proposed a revised pT stage in which color-diffused type cancers at pT3 or pT4a stage were reclassified into pT4b stage. In two-step multivariate analysis, revised pT stage (stage pT4b for all color-diffused types) proved more suitable for determining prognosis, surpassing both Union for International Cancer Control/American Joint Committee on Cancer pT stage and MSC type as an independent prognostic index. CONCLUSIONS MSC type is a significant and independent prognostic index of OS in patients with radically resected stage pT3-pT4b GC. For prognostic purposes, tumors of color-diffused type at pT3 or pT4a stage should be considered stage pT4b disease.

Abstract
BACKGROUND Tumor deposits, nodules in the peritumoral adipose tissue with no architectural residue of lymph node, have previously been described in colorectal adenocarcinomas. To date, however, there has been no examination of tumor deposits in head and neck squamous cell carcinoma (HNSCC). METHODS Neck dissection specimens of 140 patients with HNSCC were reevaluated for tumor deposits. RESULTS Tumor deposits were detected in 24 cases (17%). Cases with tumor deposits had more lymphatic invasion (p = .007), higher pathological N classification (p = .00), and more frequently showed distant metastasis (p = .003). Disease-free and overall survival were significantly shorter for tumor deposit positive cases (p = .016 and p = .005, respectively). Only tumor deposits were significant for overall survival. Tumor deposits increased the risk of recurrent disease 2294 times. Tumor deposits and pericapsular invasion were identified as independent prognostic markers; tumor deposits increased the risk of death from disease 3.4 times, whereas pericapsular invasion was associated with a 2.2-fold increase in the risk of death. CONCLUSION These results highlight the existence of tumor deposits in neck dissection specimens of HNSCC and their association with poor prognosis. © 2015 Wiley Periodicals, Inc.

Abstract
We performed this study to examine the prevalence of tumor deposits (TD) in gastric adenocarcinomas (GACa), and the relevance of their presence, size and type to clinical outcome. Ninety-six patients, histopathologically diagnosed as GACa following a total/subtotal gastrectomy were included, and clinicopathologic data were recorded. Due to the statistical analysis, the majority of TD(+) cases were of intestinal type and showed vascular invasion. In these cases, the incidence of local recurrence was significantly higher. The majority of GACa of intestinal type with TD were of high grade and showed vascular invasion. Recurrence and death were more commonly encountered among them. The recurrence-free survival (RFS) was significantly shorter in patients with TDs, which was also confirmed by multivariate analysis, and there was a significant difference between both RFS and overall survival of TD(+) and TD(-) cases of intestinal type GACa. In conclusion, in this study, we demonstrate that TDs are not infrequently observed in GACa, they are more commonly associated with the intestinal type and vascular invasive gastric cancers. Our study shows the prognostic impact of TDs, especially regarding the RFS. Therefore, the documentation of TDs might be considered for prospective studies, especially for the intestinal type GACa, a shortcoming of this study.

Abstract
Lymph node involvement is one of the most important prognostic indicators of carcinoma of the digestive tract. Although the therapeutic impact of lymphadenectomy has not been proven and the number of retrieved nodes cannot be considered a measure of successful cancer surgery, an adequate lymph node count should be guaranteed to accurately assess the N-stage through the number of involved nodes, lymph node ratio, number of negative nodes, ratio of negative to positive nodes, and log odds, i.e., the log of the ratio between the number of positive lymph nodes and the number of negative lymph nodes in digestive carcinomas. As lymphadenectomy is not without complications, sentinel node mapping has been used as the rational procedure to select patients with early digestive carcinoma in whom nodal dissection may be omitted or a more limited nodal dissection may be preferred. However, due to anatomical and technical issues, sentinel node mapping and nodal basin dissection are not yet the standard of care in early digestive cancer. Moreover, in light of the biological, prognostic and therapeutic impact of tumor budding and tumor deposits, two epithelial-mesenchymal transition-related phenomena that are involved in tumor progression, the role of staging and surgical procedures in digestive carcinomas could be redefined.

Abstract
BACKGROUND Metastatic nodules in perigastric adipose tissue without evidence of lymph node tissue have been reported in gastric cancers. However, the morphological features and clinical significance of perigastric tumor deposits (TD) have not been clarified in gastric cancers. METHODS To demonstrate the clinical implication of perigastric TD, 653 consecutive gastric cancer patients were enrolled and all of their slides were reviewed. Separate tumor nodules in the perigastric fat were classified as perigastric TD and correlated with clinicopathologic features and patient survival. RESULTS Perigastric TD were observed in 156 (23.9 %) of 653 patients. Perigastric TD were associated with synchronous distant metastasis (p < 0.001), independently of depth and venous invasion. There was a significant difference between the overall survival of those with and without TD by univariate (p < 0.001) and multivariate (p = 0.001) survival analyses. However, distant metastasis or patient prognosis could not be predicted by the morphologic patterns of the TD (p > 0.05). When TD without lymph node tissue and lymph node metastasis were recorded separately, TD were observed in 13 node-negative patients. The overall survival of node-negative patients with TD was significantly worse than that of node-negative patients without TD (p < 0.001). CONCLUSIONS Perigastric TD significantly correlated with distant metastasis and satisfactorily predicted patient outcomes independently of invasion depth, lymph node metastasis, and other clinicopathologic factors. Our findings suggest that perigastric TD should be included in the staging of patients with gastric cancer.
