My husband has stage IV RCC with metatastisis to the lungs. He has been on Nexavar since Sept. 06. His tumor on the lungs is growing. The Oncologist is thinking about switching him to Sutent if the next CT is not good. He has had awful side effects with Nexavar and is not looking forward to more side effects with Sutent. Can anyone provide any info about Sutent's side effects. I know what the website lists but would love to hear from personal experiences please?
