Prognostic factors for overall survival in patients with early gastric cancer: a retrospective cohort study based on SEER database

Age, gender, race, the number of dissected lymph nodes, LNM, invasion depth, and tumor size are independent factors affecting the prognosis of EGC patients. There are also differences in risk factors affecting prognosis among different age groups and different gender groups. The optimal cut-off point for tumor size was 20 mm, which can exert a significant impact on the prognosis of EGC patients without LNM or those aged ≥60 years. These findings can provide guidance for clinical decision-making. Identifying high-risk patients with different clinical characteristics can offer certain evidence-based support for the precise treatment of patients with EGC, thereby improving the overall patient management.
