Clinicopathological characteristics and long-term prognosis of peritoneal and retroperitoneal gastrointestinal stromal tumors.

ABSTRACT:

Background

Peritoneal and retroperitoneal gastrointestinal stromal tumors (PRGISTs) are exceedingly uncommon, and their clinicopathological characteristics and long-term prognosis remain unreported. Therefore, our objective is to analyze these aspects of patients with PRGISTs using the Surveillance, Epidemiology, and End Results (SEER) database.

Methods

Patients diagnosed with PRGISTs and small intestine stromal tumors (SISTs) between 2000 and 2019 were included in the study. Differences between groups were compared using Chi-square tests. Kaplan-Meier analysis and Cox proportional hazards models were used to evaluate overall survival (OS) and cancer-specific survival (CSS).

Results

A total of 3817 patients were enrolled, with 3513 diagnosed with SISTs and 304 with PR
