The objective of this research was to develop a predictive model for assessing the prognosis of patients with TD-positive GC.<h4>Methods</h4>Retrospective analysis was performed on the data of 4,972 patients treated for GC with D2 radical gastrectomy at Wannan Medical College's Yijishan Hospital between January 2012 and December 2021. The patients were categorized based on the number of TD (L1: 1, L2: 2-3, L3: ≥4) and the anatomical location of TD (Q1: single area, Q2: multiple areas). In a 3:1 ratio, patients were randomly assigned to one of two groups: training or validation.<h4>ResultsPeerJe17751https://www.ebi.ac.uk/biostudies/studies/S-EPMC11246019biostudies-literatureConstruction and validation of a prognostic model for gastric cancer patients with tumor deposits.PMC11246019Chen KXu RZhang YWang ZZhao JfalseConstruction and validation of a prognostic model for gastric cancer patients with tumor deposits.<h4>Background</h4>Tumor deposits (TD) was a significant risk factor impacting the prognosis of patients diagnosed with gastric cancer (GC), yet it was not currently incorporated into TNM staging systems.
