ABSTRACT
With the lifestyle change of the public,the number of fatty is increased continuously.Many studies have shown that obesity,one of the threatening factors of human health,is closely associated with the occurrence and development of tumor.A large number of clinical studies evidences have demonstrated that tumor cell proliferation and metastasis are performed and promoted by adipocytokines,inflammatory processes and insulin resistance from obesity.Adipocytokines is the crucial active substance secreted by adipose tissue,which is involved in the occurrence and development of tumor.Besides,the resistin and leptin are two important adipocytokines.Therefore,the further study on factors associated with obesity will have great significances for the diagnosis and prognosis of tumor.
