I suggest you contact hospice because not only do they do a wonderful job of helping your loved one have the best quality of life possible during such a horrible time, but they also provide so much support to the family. They can help you know what to expect. They even have booklets that detail "when the end is near" and what to expect. Hospice is a wonderful support for everyone involved.
I'm sorry your husband has run out of luck. My husband was on Torisel for 8 months and is now on Sutent (in his 5th cycle). He will have scans in 3 days...we pray for good news. Oh, how I hate cancer! You and your husband are in my prayers.
