Abstract

Background/Aims
Although several studies have shown that sarcopenia is associated with poor outcomes in colorectal cancer patients, the impact of sarcopenia on the development of colorectal neoplasia remains unclear. We aimed to evaluate the prevalence and association of colorectal neoplasia, especially advanced colorectal neoplasia, in adults with sarcopenia.
Methods
We retrospectively analyzed the data for 10,676 adults who underwent firsttime colonoscopy and bioelectrical impedance analysis (BIA) on the same day in a health screening program at a single center. Sarcopenia was diagnosed using established BIA-based criteria as adjusted appendicular skeletal muscle mass (ASM) divided by body mass index (BMI) (ASM/BMI), height (ASM/height2), or weight (ASM/weight). Prevalence of overall and advanced colorectal neoplasia and their association with sarcopenia, as established by the aforementioned diagnostic criteria, were evaluated.
Results
Among 10,676 subjects, 583 were diagnosed with sarcopenia using ASM/ BMI. Subjects with sarcopenia had a higher prevalence of colorectal neoplasia than those without. In the multivariate analysis after adjusting for confounding factors, sarcopenia was an independent risk factor for any colorectal neoplasia (odds ratio [OR], 1.31; 95% confidence interval [CI], 1.09 to 1.56) and advanced colorectal neoplasia (OR, 1.97; 95% CI, 1.27 to 3.06). The association between sarcopenia and advanced colorectal neoplasia remained significant for all sarcopenia measures including ASM/height2 (OR, 2.19; 95% CI, 1.24 to 3.85) and ASM/weight (OR, 2.41; 95% CI, 1.54 to 3.77).
Conclusions
Prevalence of overall and advanced colorectal neoplasia was higher in subjects with sarcopenia than in those without. Sarcopenia was a significant risk factor for colorectal neoplasia, especially for advanced colorectal neoplasia.
