Prognostic Nomograms for Nonelderly Adults with Gastric Signet Ring Cell Carcinoma.

ABSTRACT:

Background

Nomograms were established to predict the survival for gastric signet ring cell carcinoma (GSRC) in young and middle-aged adults. Material and Methods. Eligible patients with GSRC from 2004 to 2015 were collected from the Surveillance, Epidemiology, and End Results (SEER) database and then divided into a training and a testing cohort in proportion. Independent prognostic factors were picked by univariate and multivariate Cox regression analysis to set up nomograms. The predictive effect and clinical value of nomograms were evaluated by the concordance index (C-index), calibration curves, and receiver operating characteristic curve (ROC).

Results

A total of 1686 GSRC patients were subsumed into this case for analysis, including a training (n = 1180) a
