Clinicopathological features and prognosis of patients with gastric neuroendocrine tumors: A population-based study.

ABSTRACT:

Background

Despite its rarity, studies have shown the incidence of gastric neuroendocrine tumors (G-NETs) is increasing. This study investigated the risk factors affecting the survival of G-NETs patients and their prognosis over time.

Method

A retrospective analysis of 506 G-NETs patients who underwent surgery for nonmetastatic disease from the Surveillance, Epidemiology and End Result database from 1988 to 2011 was conducted. Multivariate Cox regression analyses identified the prognostic factors affecting overall survival (OS) and disease-specific survival (DSS). Three-year conditional survival (COS3 and CDS3) estimates at "x" year after treatment were calculated as follows: COS3 = OS(x + 3)/OS(x) and CDS3 = DSS(x + 3)/DSS(x).

Results

The 1-, 3-, and 5-year OS rates
