My stage 4 renal cell cancer has returned after 5 years with no tumors after surgery and use of Sutent. My oncologist is suggesting Votrient as the next drug to try. I have been taking 1g/day of DCA for a week now and wish to continue with the DCA if I decide to start the Votrient. Does anyone have any experience with mixing these two drugs or any insight. Any help is appreciate.
