I'm sorry to hear about the bad side-effects of Xeloda for you. I did well on it for several months last year, but I know it has been hard for others. I am currently on Folfox. The Folfox protocol includes oxaliplatin and folinic acid infused, and then 5-fu on a pump for 46 hours. I have advanced-stage metastatic disease, and have done seven rounds of Folfox since mid-June. Happily, where I've had no response to other chemo agents like Gemzar, we have seen shrinkage and stabilization with Folfox.
That said, I have had side effects, including bilateral neuropathy (fingers) from the Oxaliplatin, and lately more fatigue and nausea from the cumulative effects of the chemo. I am currently skipping a round to recuperate (and get my platelets out of the basement).
That has been my experience, and from others I've talked to it's not atypical. The good news is that for some of us this cocktail seems to be effective where other agents have not, which has made some of the negative effects seem more tolerable. Of course, everyone is different, so we will hope you have very limited side effects.
Wishing you the best, Mark
