Hi Jane!
Glad you found these forums, so sorry you had to my dear!
First things first, get your mom to a Comprehensive Cancer Center ASAP! Taking a multidisciplinary approach to this cancer using the latest treatment protocols is essential to survival really, you want the absolute best medical advice available to you and people who deal with this disease everyday. It just gives your mom the best possible outcome.
I'll tell you that if she's
HPV+ then
Erbitux isn't the best chemo for her and she should be in radiation as chemotherapy in this disease isn't curative. Surgery, radiation are the only way to kill this cancer with chemo being a clean up/addition to radiation usually. This is really why you need a second opinion ASAP.
If you have staging information and more details etc, that helps with advice too. We are here to help my dear

Hang in there, plug into these forums, as Caregivers you've just come into the hardest job on the planet, there are plenty of "angels of mercy" aka caregivers on these forums that can help.
Glad you found us, more details the better

Eric
