I'm sorry for the bad news. As Christine mentioned, chemo. I had heard of TPF Induction Chemo, Taxotere, Cisplatin, 5-FU, used midway or after cancer treatment, that may have be the only thing to significantly reduce or eliminate the tumors for additional treatment, surgery afterwards or to continue treatment. I hope you find other answers. I only had 5 days of TPF, and it killed all my tumors in the Tonsil, BOT, Valleculla, two lymph nodes, but it lasts less than a year before cancer returns, so further treatment is needed. Its usually 3 5 day cycles spaced 3 weeks apart. Mine lasted 8 months, but only came back in one lymph, and then had radiation to follow, then other treatments as recurrences continued. Good luck. I hope to see something else.

Forgot to add clinical trials. There are a number of them for recurrent SCCHN, especially with targeted therapies.
