Your mother is in a very tough spot. I believe the American Cancer Society website maintains a list of all of the trials going on and you can search them by the type of cancer you have. I would be looking at all of those and especially those that are Phase III with few side effects. Or even Phase II with few side effects or even with side effects if results in Phase I or II were very good.
In 1994 I found a 3cm tumor on my right tonsil. After 3 rounds of chemo, I underwent a radical neck dissection with a peck flap. I had a reoccurance which required twice a day radiation treatments and then had 19 years cancer free. I then found a very small tumor on my right tonsil. It was removed. Then I found a 1 cm mass near the base of my tongue on the left side. I had two partial glossectomys with bad margins and then then underwent Brachytherapy.
