Population-based analysis highlights no survival advantage of radical resection for appendiceal neuroendocrine tumors, suggesting local resection may be sufficient.
Key Points
Patients undergoing local resection had a significantly better 5-year overall survival than those undergoing radical resection.
Multivariate Cox analysis showed that surgical modality was not an independent prognostic factor for survival outcomes.
Propensity score matching was used to compare outcomes while minimizing selection bias between surgical groups.
The Kaplan-Meier method revealed significant differences in cancer-specific survival between local and radical resection.
