Methods: 36 GC patients (GC group) and 38 patients with benign gastric lesions (control group) admitted to Tianjin Wuqing Hospital of Traditional Chinese Medicine from January 2023 to October 2024 were selected. Flow cytometry was used to detect peripheral blood Th17 cell amount in each group, and Enzyme-Linked Immunosorbent Assay (ELISA) was used to measure IL-17 and MMP2 levels in the serum. The application value of these three detection indicators in the lymph node metastasis of GC, as well as the diagnostic efficacy of their combined detection, were evaluated. Results: Compared with control group, patients in the GC group showed a significant increase in Th17 cell levels in peripheral blood and prominently higher serum IL-17 and MMP2 levels, with statistical significance (all p < 0.05). In the GC group, the amount of Th17 cells, serum IL-17, and MMP-2 was significantly higher in patients with lymph node metastasis compared to those without metastasis, and the differences were statistically significant (all p < 0.05). The accuracy, specificity, and sensitivity of the combined detection of Th17, IL-17, and MMP2 were 95.82%, 94.21% and 97.69%, respectively. Compared with single detection, they were significantly higher, and the differences were statistically significant (all p < 0.05). Conclusion: Th17 cells, IL-17, and MMP2 are associated with lymph node metastasis in GC, and their combined detection can help in the differential diagnosis of GC.展开更多
