Effect of preoperative skeletal muscle area and prognostic nutritional index values on postoperative morbidity and mortality in patients with gastric cancer: a single-center retrospective analysis.

As a result, preoperative SMA and PNI values were found closely related to the postoperative hospital stay, morbidity and mortality results of patients with gastric cancer. Preoperative nutritional support may help to overcome longer hospital stay, higher mortality and morbidity rates in patients with gastric cancer.
