Chromophobe (ChRCC) Type Renal Cell Cancer – pro

Chromophobe(ChRCC) renal cell cancer is rare.  Unfortunately, there are no proven treatment for the metastatic disease. At one time chemotherapy was thought to be effective but  studies did not confirm it. Overexpression of CD117 on cellular membranes of ChRCC could be a potential target for kinase inhibitors like: imatinib, dasatinib, nilotinib. The potential targets for other kinase inhibitors (sunitinib and sorafenib) in ChRCC seem to be VEGFR and PDGFR. In conclusion, these observations are the basis for formulating research hypotheses which should be verified in prospective studies.
