A recent study investigated the role of lymphadenectomy (LA) in the prognosis of patients with small intestinal stromal tumors (SISTs) using data from the SEER database (2000-2019). The analysis included 2412 patients, with 879 undergoing LA and 1533 not undergoing LA. Key methods included multiple imputation for missing data, propensity score matching to reduce bias, and Kaplan-Meier and Cox proportional hazards models for survival analysis.
Results:
No significant difference in overall survival (OS) and cancer-specific survival (CSS) between the LA and non-LA groups.
After matching, 1596 patients (798 LA and 789 non-LA) still showed no differences in long-term OS and CSS.
For patients over 60, CSS was better in the non-LA group.
Age, M stage, marital status, and mitotic rate were significant risk factors influencing survival outcomes.
Clinical Implications:
LA may not provide a survival benefit in SISTs.
For patients older than 60, avoiding LA could be more beneficial.
Consider these findings when planning surgical interventions for SIST patients.
