Key Points Question Can the accuracy of prognosis prediction be improved using a tumor-associated collagen signature of gastric cancer (TACSGC) to detect patients who are likely to benefit from adjuvant chemotherapy for GC? Findings In this cohort study of 519 patients, a low TACSGC level was associated with a better prognosis, and patients with stage II and III GC with a low TACSGC level were more likely to benefit from adjuvant chemotherapy. Meaning The findings suggest that TACSGC may improve the accuracy of prognosis prediction and provide a helpful reference for decision-making regarding adjuvant chemotherapy in GC.
