Developing a modified textbook outcome for elderly patients with gastric cancer: a multi-center study

Objective Textbook outcome (TO) is widely recognized as a comprehensive prognostic indication for patients with gastric cancer (GC). This study aims to develop a modified TO (mTO) for elderly patients with GC. Methods Data from the elderly patients (aged ≥ 65 years) in two Chinese tertiary referral hospitals were analyzed. 1389 patients from Fujian Medical University Union Hospital were assigned as the training cohort and 185 patients from Affiliated Hospital of Putian University as the validation cohort.
