SUMMARY OBJECTIVE: This study aims to explore the role of ERCC5 genetic polymorphisms in gastric cancer and their relationship with metastasis and recurrence of gastric cancer. METHODS: A total of 200 patients with gastric cancer and 133 healthy subjects were enrolled. MassARRAY iPLEX® technology was used to genotype ERCC5 rs2016073, rs751402, rs2094258, rs2296147, and rs2296148 between the control group and the gastric cancer group. The relationship of ERCC5 genetic polymorphisms with metastasis and recurrence of gastric cancer was explored. The differences in sociodemographic characteristics between patients with gastric cancer and control subjects were compared using the chi-square test. The genetic loci between the control group and the gastric cancer group were analyzed by the chi-square test. RESULTS: There was no significant difference in the metastasis of gastric cancer between males and females (p=0.628), but there was a significant difference in the metastasis of gastric cancer (p=0.005). Patients aged ≤60 years and >60 years showed no significant difference in the metastasis of gastric cancer (p=0.420), but there was a significant difference in the recurrence of gastric cancer (p<0.001). The loci rs2016073, rs751402, and rs2094258 in the gastric cancer group showed no significant differences compared with the control group (p=0.194), and the loci rs2296147 and rs2296148 showed significant differences. CONCLUSIONS: The results suggested that ERCC5 polymorphisms (e.g., rs201607, rs751402, rs2094258, rs2296147, and rs2296148) may be associated with metastasis and recurrence of gastric cancer.
