BACKGROUND: Stair climbing test (SCT) and gait speed test (GST) are two physical performance measures, both of which are associated with postoperative outcomes. However, few studies have compared these two tests for the prognostic value.
METHODS: A prospective study was conducted in patients undergoing radical gastrectomy for gastric cancer. Handgrip strength (HGS) test, 7-steps SCT and 6-m GST were performed before surgery. Body compositions were analyzed using abdominal computed tomography (CT). Sarcopenia was diagnosed by low HGS plus either low muscle mass or quality.
RESULTS: A total of 548 patients were included in this study. Time of GST and SCT were both significantly correlated with HGS, skeletal muscle index and skeletal muscle density, but not with subcutaneous or visceral fat area. Low SCT performance (SCT time ≥12.65s) was associated with higher incidence of postoperative complications and longer postoperative length of stay, whereas low GST performance (GST time ≥5.45s) did not. Low performance in SCT and GST were both associated with worse overall survival (OS) and disease-free survival (DFS) after surgery. Low SCT performance was an independent predictor for postoperative complications, OS, and DFS, whereas low GST performance was not significant in multivariate analyses adjusting for the same covariates. The combination of sarcopenia with low SCT performance showed higher accuracy in predicting postoperative complications and mortality compared with sarcopenia combined with low GST performance.
CONCLUSION: SCT outperformed GST in predicting outcomes after radical gastrectomy for gastric cancer, either as a singular indicator or in combination with sarcopenia assessments.
