ABSTRACT
Despite a higher incidence and less favorable outcome of malignant tumors in obese patients, much less recognized is the link between obesity and cancer. The mechanism of the association of obesity with carcinogenesis remains incompletely understood. Postulated mechanisms include insulin resistance, insulin-like growth factor signaling, chronic inflammation, immunomodulation, hyperglycemia-induced oxidative stress, and changes of intestinal microbiome. Insulin resistance leads to direct mitogenic and antiapoptotic signaling by insulin and the insulin-like growth factor axis. Obesity can be considered to be a state of chronic low-grade inflammation. In obesity, numerous proinflammatory cytokines are released from adipose tissue which may involve in carcinogenesis. Hyperglycemia in susceptible cells results in the overproduction of superoxide and this process is the key to initiating all damaging pathways related to diabetes. This hyperglycemia-induced oxidative stress could be one possible link among obesity, diabetes, and cancer development. The role of obesity-related changes in the intestinal microbiome in gastrointestinal carcinogenesis deserves further attention.
