Prognostic models based on lymph node density for primary gastrointestinal melanoma: a SEER population-based analysis.

ABSTRACT:

Objective

This study aimed to construct prognostic models to predict the overall survival (OS) and cancer-specific survival (CSS) of patients with primary gastrointestinal melanoma (PGIM).

Design

An observational and retrospective study.

Setting

Data were obtained from the Surveillance, Epidemiology and End Results (SEER) programme database, encompassing a broad geographical and demographic spectrum of patients across the USA.

Participants

A total of 991 patients diagnosed with PGIM were included in this study.

Methods

A total of 991 patients with PGIM were selected from the SEER database. They were further divided into a training cohort and a validation cohort. Independent prognostic factors were identified by Cox regression analysis. Two prognostic mod
