Prognostic Impact of Preoperative Assessment of Muscle Mass and Strength in Surgically Resected Lung Cancer.

Background/aim: The association between resected non-small cell lung cancer (NSCLC) and long-term outcomes of muscle mass depletion and muscle weakness has also not been well documented. This study evaluated whether muscle mass depletion assessed by bioelectrical impedance analysis (BIA) and low muscle strength assessed by the peak expiratory flow rate as a percentage of predicted value (%PEFR) were associated with surgical outcomes in patients with resected NSCLC.

Patients And Methods: This retrospective study included 219 patients with resected NSCLC between 2016 and 2021.

Effect of Postoperative Muscle Loss After Resection of Non-small Cell Lung Cancer on Surgical Outcomes.

Background/aim: Preoperative depletion of psoas muscle mass index (PMI) in lung cancer patients is an unfavorable prognostic factor. The relationship between post-surgical changes in PMI and survival is not clear. Therefore, we conducted a retrospective study to clarify the prognostic significance of preoperative and postoperative PMI changes.
