Asynchronous Recovery of Body Composition After Curative Surgery for Gastric and Colorectal Cancer: A Prospective Longitudinal Study

Background and Aims: Postoperative recovery of body composition in patients with gastric cancer (GC) and colorectal cancer (CRC) is a complex and dynamic process. However, longitudinal recovery patterns across multiple physiological domains remain incompletely characterized. This study aimed to describe longitudinal changes in body composition over 12 months after curative surgery in patients with GC and CRC.
