Is skeletal muscle mass an optimal marker for postoperative outcomes in lung cancer patients?

Lung resection is a standard therapeutic option for early- stage non-small cell lung cancer (NSCLC) and it is widely performed in developed and developing countries (1). Despite recent progress of imaging technology and surgical devices, postoperative outcomes have not been changed for decades (2,3). For improving postoperative outcomes, appropriate markers that have potential to stratify risk of postoperative outcomes are necessary in preoperative management.
