Significantly higher concentrations of visfatin have been observed in patients with highly advanced cancers versus lower advanced cancers, p = 0.0002, and in the case of the invasion of blood vessels, p = 0.02, and lymph node metastases, p = 0.01, in reference to the depth of infiltration of the endometrium, p = 0.004, as well as the size of the tumor, p = 0.003. This evidence concerns the gene NAMPT and cancer.
