Abstract

The purpose of the current study was to compare the outcomes of patients with gastric cancer (GC) between the type 2 diabetes mellitus (T2DM) group and the non‑T2DM group. The PubMed, Embase and Cochrane Library databases were searched from inception to March 8, 2022, to identify propensity score matching (PSM) studies that analyzed the effect of T2DM on the outcomes of patients with GC. Total complications, overall survival (OS), disease‑free survival (DFS) and cancer‑specific survival (CSS) were compared between the T2DM group and the non‑T2DM group. A total of four PSM studies with 834 patients were included in the current study. There were 311 and 523 patients in the T2DM group and the non‑T2DM group, respectively. Baseline characteristics of the two groups were adjusted with PSM in all the four studies, however, no significant difference was found in baseline characteristics (P>0.05). DFS was significantly worse in the T2DM group compared with that in the non‑T2DM group [hazard ratio (HR), 1.45; 95% confidence interval (CI), 1.10‑1.90; P=0.007)]. However, after pooling up the data, there was no significant difference between the T2DM group and the non‑T2DM group in terms of OS (HR, 1.41; 95% CI, 0.92‑2.16; P=0.11), CSS (HR, 1.29; 95% CI, 0.92‑1.81; P=0.14) and total complications (odds ratio, 1.01; 95% CI, 0.64‑1.60; P=0.95). Patients with GC and T2DM are associated with poor DFS. However, there were no significant differences between the T2DM group and the non‑T2DM group in terms of OS, CSS and total complications.
