Prognostic significance of preoperative skeletal muscle status in patients with gastric cancer after radical gastrectomy.

Background And Objectives: The association between skeletal muscle status and gastric cancer (GC) prognosis remains unclear. Here, we investigated the impact of the skeletal muscle index (SMI) on overall survival (OS) in GC patients after radical gastrectomy.

Methods And Study Design: We divided 178 patients into four groups: adult men, adult women, elderly men and elderly women.
