Survival effects of primary and metastatic surgical treatment in metastatic small intestinal tumors: A propensity score-matching study.

ABSTRACT:

Objective

To analyze the effects of primary tumor resection and metastatic lesion resection on the survival of metastatic small intestinal tumors.

Methods

The research subjects were patients with metastatic small bowel tumors identified from 2004 to 2016 in the Surveillance, Epidemiology, and End Results (SEER) database. Propensity score matching and Kaplan-Meier analyses were performed to analyze the effect of surgery on the prognosis.

Results

A total of 4,034 patients from the SEER database were analyzed. Both before and after the propensity score-matching analysis, the prognosis of patients who underwent primary tumor surgery and metastatic surgery was better than that of patients who did not undergo surgery; all were patients with metastatic small bowel adenocarci
