Combining systemic inflammatory response index and albumin fibrinogen ratio to predict early serious complications and prognosis after resectable gastric cancer

Figure 1 Patient selection flowchart of the present study. AFR: Albumin fibrinogen ratio; ROC: Receiver operating characteristic; SIRI: Systemic inflammatory response index.

Figure 2 Receiver operating characteristic curve analysis of systemic inflammatory response index, albumin fibrinogen ratio and systemic inflammatory response index combined albumin fibrinogen ratio for early severe postoperative complications in gastric cancer. Systemic inflammatory response index (SIRI): Area under the curve (AUC) = 0.765, 95% confidence interval (CI): 0.714-0.815; albumin fibrinogen ratio (AFR): AUC = 0.743, 95%CI: 0.689-0.797; SIRI-AFR: AUC = 0.779, 95%CI: 0.737-0.820.

Figure 3 Kaplan-Meier analysis of overall survival and disease-free survival based on the systemic inflammatory response index-albumin fibrinogen ratio score in gastric cancer patients. P value was calculated by the log-rank test. A: Overall survival; B: Disease-free survival. AFR: Albumin fibrinogen ratio; SIRI: Systemic inflammatory response index.

Figure 4 Kaplan-Meier analysis of overall survival and disease-free survival based on the systemic inflammatory response index-albumin fibrinogen ratio score of gastric cancer patients in the subgroup. A and B: Patients with tumor-node-metastasis (TNM) I-II; C and D: Patients with TNM III; E and F: Patient received no perioperative transfusion; G and H: Patient received perioperative transfusion; I and J: Patient negative for carcinoembryonic antigen (CEA); K and L: Patient positive for CEA; M and N: Patient without postoperative major complications; O and P: Patient with postoperative major complications. P value was calculated by the log-rank test. SIRI: Systemic inflammatory response index; AFR: Albumin fibrinogen ratio.
