I responded earlier to your question, but just realized that you may not have been notified as my response didn't go directly to you. I have Stage III Renal Cell Carcinoma and have found an incredible amount of info regarding treatments at the Kidney-Onc Mail List. Go to this site to sign up for the Mail List and you will be able to talk to more than 800 individuals with kidney cancer and share their experiences. They also have a fantastic archive that you can search to get information on specific treatments.
