anal cancer poor chemo candidate

I have an elderly patient with a T3N0 anal squam. Not a great 5FU/MMC candidate per med onc. If you were to try to twist the arm of med onc into something radiosensitizing, what would you consider? xeloda or weekly cis? I see this case series using just 5FU. Any thoughts are appreciated.
