The value of L3 skeletal muscle index in evaluating preoperative nutritional risk and long-term prognosis in colorectal cancer patients.


ABSTRACT: L3 skeletal muscle index (L3SMI) was reportedly related to postoperative outcomes. We aimed to investigate the value of L3SMI in evaluating preoperative nutritional risk and long-term prognosis in colorectal cancer (CRC) patients. We retrospectively enrolled 400 CRC patients who underwent surgery from January 2012 to December 2014. The L3SMI was calculated by preoperative computed tomography (CT) and classified into two groups by gender quartile method. We found that the CT diagnostic criteria of sarcopenia in South China population was: male ?38.89cm2/m2, female ?33.28cm2/m2. Multivariate logistic regression analysis showed that low L3SMI was an independent risk factor for preoperative nutritional risk (p?
