Abstract

Background: The association between sarcopenia and postoperative outcomes for patients with gastrointestinal malignancies remains controversial. This study aimed to assess the impact of sarcopenia on short- and long-term outcomes after surgery for esophagogastric junction cancer (EGJC) or upper gastric cancer (UGC). Methods: The study reviewed 148 patients with EGJC or UGC who underwent surgical resection. The patients were categorized into the sarcopenia group or the non-sarcopenia group according to their skeletal muscle index calculated using abdominal computed tomography images. The study compared clinicopathologic factors, postoperative complications, and prognosis between the two groups. Results: Sarcopenia was present in 19 patients (32.2%) with EGJC and 23 patients (25.8%) with UGC. The 5-year overall survival (OS) and recurrence-free survival (RFS) rates were significantly poorer in the sarcopenia group than in the non-sarcopenia group (OS 85.5 vs 54.8%, P = 0.0010; RFS 78.7 vs 51.7%, P = 0.0054). The development of postoperative complications did not differ significantly between the two groups. Both the uni- and multivariate analyses showed that N stage (P < 0.0001) and sarcopenia (P = 0.0024 and 0.0293, respectively) were independent poor prognostic factors for OS. Conclusions: Sarcopenia was strongly associated with a poor long-term prognosis for patients with EGJC or UGC who underwent surgery. The results suggest that special attention might be needed during the development of treatment strategies for patients with sarcopenia who intend to undergo operations for EGJC and UGC.
