My dad was diagnosed with Stage 4 Renal Cell Carcinoma. He started a treatment this week. The treatment is call Torisel. I wonder if anyone has any experience in this drug. If it worked for your loved one and if there was any side effects and how long did it take to have the side effects. Do you know what I found? I believe this is one of the newer mTOR targeted therapy drugs. It is very new. You would probably get more response and better information by going to an online support group with other patients who are using this drug. Good luck.
