The expression of GHRH receptors has been found in primary human prostatic, breast, endometrial, lung, adrenal carcinomas and uveal melanomas, as well as in experimental human cell lines of virtually all major types of malignancies, including prostatic, ovarian, breast, endometrial, lung (SCLC and non-SCLC), colorectal, gastric, pancreatic, renal, glioblastomas, osteogenetic and Ewing sarcomas, lymphomas, and uveal melanomas [3, 10, 11, 14, 15, 23, 26, 33–37]. This evidence concerns the gene GHRHR and uveal melanoma.
