abstract = {Background: Although a decrease in the psoas muscle area (PMA) has been reported as a risk factor for survival after esophagectomy in esophageal cancer, no previous studies have focused on the change in the PMA after surgery. We investigated the prognostic role of PMA changes in patients with surgically treated esophageal cancer.
Methods: Fifty-eight patients with esophageal cancer who underwent surgical resection and complete lymph node dissection were reviewed retrospectively. The PMA was measured at the level of the L3 vertebrae on preoperative and one-year postoperative follow-up computed tomography images. The percentage change of the PMA was calculated as follows: delta (%) = (postoperative PMA − preoperative PMA) / (preoperative PMA × 100).
Results: The study patients included 54 (93.1%) males and 4 females (mean age, 60.59±9.16 years), of whom 17 (29.3%) were pathological Stage I, 18 (31.0%) were Stage II, and 23 (39.7%) were Stage III. The mean change of the PMA was −10.17% and the postoperative PMA was decreased significantly compared with the preoperative PMA (P},
