ARTICLE HIGHLIGHTS
Research background
The incidence of signet ring gastric carcinoma has increased among the past decades. Several inflammation indexes, including ratio of lymphocytes to monocytes (LMR), have been shown to be effective predictors of gastric cancer prognosis.
Research motivation
The predictive accuracy of ratio of LMR for signet ring gastric cancer is unclear now.
Research objectives
To assess the prognosis predictive accuracy of preoperative LMR for signet ring gastric cancer.
Research methods
Our research center conducted a retrospective analysis of clinical data from patients diagnosed with signet ring gastric carcinoma over the past 5 years, identifying factors that significantly affect patients’ survival by using single factor analysis, and deciding independent prognostic factors related to signet ring cell gastric cancer by using multivariate analysis.
Research results
The results of the single factor analysis indicated a strong correlation between the survival of signet ring gastric cancer patients and several factors, including tumour invasion, lymph node metastasis, pTNM stage, surgical approach, age, carcinoembryonic antigen (CEA), platelet-to-lymphocyte ratio (PLR), LMR, ALB, PNI and FIB. Furthermore, the multivariate analysis revealed that age, tumor invasion depth, pTNM stage, preoperative CEA level, and preoperative LMR level were independent factors related to the prognosis of signet ring gastric cancer.
Research conclusions
In signet ring gastric cancer patients, a low preoperative LMR level is indicative of a poor prognosis. The death risk ratio of the low LMR group compared to the high LMR group is 1.776.
Research perspectives
The study subjects were followed up for 5 years and divided into survival group and death group. Clinical data, pathological data, and prognosis of the two groups of patients were observed.
