I am interested in finding out how the side effects from Torisel compare to those of Sutent. I was diagnosed with stage 4 RCC with mets to the lungs and had my left kidney removed on October of 2006. I have been on Sutent since about February 2007. I got the results of my latest CT scan today and my tumors in my lungs have increased in size by about 40%. I will start Torisel on Monday. Hopefully I will have some positive results on Torisel.
