Key clinical point: The body composition variables were associated with major postoperative complications in patients with gastric cancer who received preoperative chemotherapy followed by gastrectomy.
Major finding: A high skeletal muscle (SM)-mass Z-score (difference in each patient’s standard deviation from the mean value) was associated with a lower risk for major postoperative complications (relative risk [RR] 0.47, P = .004). High visceral adipose tissue-radiation attenuation (VAT-RA; RR 2.82; P = .001) and subcutaneous adipose tissue-RA (SAT-RA; RR 1.95; P = .015) Z-scores were associated with an increased risk for major postoperative complications.
Study details: This was a side study of 112 patients with gastric cancer who received preoperative chemotherapy followed by gastrectomy in the LOGICA trial. The preoperative computed tomography scan was used to calculate the mass and RA for SM, VAT, and SAT.
