Obesity is linked significantly to adipose tissue dysfunction andto alteration of adipokines in blood; in particular, obesity-induced inflammation is thought to be an importantlink between obesity and colorectal cancer. Based on epidemiological studies, we undertook a systematic reviewto understand the association of circulating levels of selected adipokines, including adiponectin, leptin, resistin,IL-6 and TNF-α, with the level of CRC risk. Most prospective studies suggested protective effects of adiponectin,but these were attenuated by body mass index (BMI) and waist circumference (WC) data in our meta-analysis.On the other hand, meta-analyses for leptin and CRC did not demonstrate any association, similar to the resultsof systematic review. Although it proved difficult to determine whether other selected adipokines (resistin, IL-6and TNF-α) were related to CRC risk due to small number of reports, the present systematic review suggesteda positive association with elevated resistin levels but null associations with IL-6 and TNF-α. https://journal.waocp.org/article_28606_af5dc80b8ff3a1316bb6211818dd6a53.pdf
