ARTICLE HIGHLIGHTS
Research background

It is controversial whether adjuvant chemotherapy is necessary for stage T2N0M0 gastric cancer.

Research motivation

To further clarify the indications for the use of postoperative adjuvant chemotherapy in patients with T2N0M0 gastric cancer.

Research objectives

To obtain a risk score to assess the need for adjuvant chemotherapy in patients with T2N0M0 gastric cancer.

Research methods

Univariate and multivariate Cox regression analyses were performed to predict factors affecting prognosis. Vascular invasion, tumor site, and BMI were assessed, and a scoring system was established. We compared the survival outcomes and benefits of adjuvant chemotherapy between the different subgroups.

Research results

Five-year survival rates of the score 0, 1, 2, and 3 groups were 92%, 95%, 80%, and 50%, respectively (P < 0.001). In the score 2-3 group, five-year survival rates for patients in the adjuvant chemotherapy group and postoperative observation group were 95% and 61%, respectively (P = 0.021).

Research conclusions

For patients with T2N0M0 stage gastric cancer and two or more risk factors, adjuvant chemotherapy after D2 gastrectomy may have a survival benefit.

Research perspectives

Individualized treatment should be adopted according to examination and pathological results in patients with T2N0M0 gastric cancer.
