Survival Outcome of Local versus Radical Resection for Jejunoileal Gastrointestinal Stromal Tumors: A Propensity Score-Matched Population-Based Analysis

Data of patients with jejunoileal gastrointestinal stromal tumors (JI GISTs) were extracted from Surveillance, Epidemiology, and End Results (SEER) database. Predictor variables (age, sex, race, marital status, year of diagnosis, income, area, tumor size, T stage, N stage, M stage, grade, mitotic rate, tumor site, chemotherapy, lymphadenectomy and mode of surgery), survival time and outcome variable (all-cause death and disease-specific death) used in this study were recoded. Propensity score matching (PSM) was performed to reduce bias between local resection (LR) and radical resection (RR) groups.The article using these datasets is published at International Journal of Colorectal Disease.
