I have a question about what to expect as this cancer progresses.

I have been a "lurker" on this forum for some time. Here is a history -
My sister (to be 40 this January) was diagnosed with SCC on her tongue late Jan. 2004. She had partial tongue glossectomy with flap reconstruction, and right neck disection surgery in Feb 2004, followed by radiation and chemo starting early April. She completed all the radiation and chemo. Mid August, what was originally thought to be an abcess in her neck, was biopsied and cultivated and the reports showed a reocurrence. Sept 1, she had the neck mass removed and interoperative radiation. She had a consultation visit with Sloan Kettering after this last surgery where they told her they agreed with all advice and procedures she had been given thus far. She began sessions of chemo (taxotear) 3 weeks on, one off for 12 weeks. After completing 7 weeks, again her cancer has reocurred, this time in the neck again, and has broken through her skin, on the underside of her chin. Her Dr's have told her, that there are no further options, and hospice/palliative care should be considered.

My question is for caregivers that have been through this. What should we expect? How does this type of cancer progress from this point? In what kind of time frame? We are in the process of arranging a home visit from the Hospice center.

As I said, I've been a "lurker" on this forum for some time now, and have found the forum very valuable in the past. I haven't seen this question addressed before. If it's not appropriate please send me a private message.

Thank you.
