Clinical Trial Summary

This study aims to develop and validate a Nomogram (mCNS) model for predicting long-term survival in elderly patients following curative resection for advanced gastric cancer. The study is a retrospective multi-center analysis involving 924 gastric cancer patients treated at the Department of Gastrointestinal Surgery of the Affiliated Union Hospital of Fujian Medical University between 2009 and 2013, and 512 patients aged 65 and above who underwent gastric resection at the Affiliated Zhongshan Hospital of Dalian University between 2011 and 2018. An online prognostic tool is introduced to assist clinicians in predicting patient prognosis and customizing treatment and follow-up strategies.


Description:

Data were collected from 1436 gastric cancer patients, of which 555 elderly patients with advanced gastric cancer were ultimately included after applying exclusion criteria. Patients were divided into training and testing cohorts from the Fujian Medical University Affiliated Union Hospital and Dalian University Affiliated Zhongshan Hospital. The study was approved by the institutional review boards with a waiver of informed consent due to the use of anonymized secondary data. The analysis utilized the Cox proportional hazards model to select key variables for predicting overall survival (OS). The study also implemented rigorous data handling procedures, including multiple imputations for missing data. The development of an online prognostic tool based on the Nomogram model is part of the project, designed to provide real-time survival predictions through a user-friendly interface for clinical application.
