This study aims to evaluate and determine the changes in QoL after gastrectomy and the relationship between BC and physical function on QoL. Methods: A total of 311 gastric cancer patients completed EORTC QLQ-C30 and EORTC QLQ-STO22 questionnaires prior to and 1, 3, 6 months post-surgery. Data including BC, handgrip strength (HGS) and 6-meter gait speed (GS) are collected prospectively. Multiple linear regression determined the correlation between preoperative and postoperative QoL and BC, HGS and GS. Results: Gastrectomy patients had significantly worse scores on most function and symptom scales (p <0.001), but most functions and symptoms recovered within 6 months after surgery. A higher subcutaneous fat area(SFA)was associated with increased symptom scores1 month post-surgery. A higher GS is associated with a better global health status and decreased symptom score. Conclusion: Patients after gastrectomy suffer from a decline in their QoL. Intervention strategies aimed at reducing SFA and improving GS may improve the QoL of gastric cancer patients.
