Aim:To investigate the association between plasma visfatin levels and risk of early and advanced colorectal cancer (CRC).Methods:In total, 358 CRC patients and 286 controls were enrolled. According to the T factor of the TNM system. cancer patients were divided into two subgroups: early and advanced cancer. Levels of visfatin, anthropometric and metabolic parameters, which were classified as low, medium, and high, based on the tertile distributions in the control group, were determined.Results:The visfatin levels in patients with advanced and early cancer were higher than in controls (least significant difference test, P = 0.004 and 0.013, respectively). The patients in the highest tertile of visfatin concentration presented significantly higher odds for early and advanced CRC, adjusted for potential confounding factors (odds ratio 3.37; 95% CI, 1.93–8.37; P = 0.011; odds ratio 2.38; 95% CI: 1.82–8.35; P = 0.015, respectively). The visfatin level correlated significantly with waist:hip ratio (P < 0.05 for all) among case and control participants. Plasma visfatin levels in early and advanced CRC yielded a receiver operating characteristic curve area of 72 and 86%, respectively. The optimal sensitivity and specificity were 73% and 57% in discriminating between early CRC and normal controls while they were 76% and 68% in discriminating between advanced CRC and normal controls.Conclusion:An increased level of visfatin was a strong risk factor for both early and advanced CRC in Chinese patients. Plasma visfatin levels might be a potential biomarker for CRC detection.
