- Abstract: PURPOSE: This study investigated the relationship between body composition and platelet-to-lymphocyte ratio (PLR) in patients with colorectal cancer (CRC).METHODS: This retrospective study included 110 patients who underwent anthropometric measurement by bioelectrical impedance analysis before surgical treatment for CRC between May 2015 and June 2018.RESULTS: According to PLR, 45 patients (40.9%) had low PLR (PLR<150), and 65 patients (59.1%) had high PLR (PLR≥150). Serum hemoglobin (P<0.001) and albumin levels (P=0.021) were significantly lower in high PLR group. Tumor mass diameter was significantly larger in high PLR group (P=0.048) and the proportion of poorly differentiated or mucinous tumors was significantly higher in high PLR group (P=0.037). All indices related to fat (body fat mass, percent body fat, body fat mass of trunk, visceral fat area, fat mass index, measured fat thickness of abdomen) and two indices related to muscle (arm muscle circumference, measured muscle circumference of abdomen) were significantly lower in high PLR group (P<0.05). According to subgroup analysis based on the sex, all indices significantly differed between PLR groups; however, in females no index was significantly different between PLR groups.CONCLUSION: Body composition indices including fat and muscle indices measured by InBody 770 were related to PLR in CRC, especially in male patients. These results suggest that low muscle and fat indices may be related to poor prognosis of CRC.
