First of all, caution on the herbs mixing with chemo. They can cause some serious problems and some herbal remedies can actually decrease the efficacy of the chemo. Check with your doc before taking anything and be totally upfront with your medical professionals
As for the stage IIB thing. If you had said you were a stage IIA, I would advise you to do the Xeloda (or 5FU/leucovorin) and not the oxi but as a stage IIB its a totally different story. Studies show that when the two segments of stage II (A & B) are looked at separately, there is no statistical advantage for a stage IIA with no negative prognositic factors to have the oxi included in the chemo protocol. However, albeit slight, there IS an advantage for the stage IIB patient. Your tumor, by being classified as a IIB, has penetrated the colon wall and attached to an adjacent organ or tissue. Had it not done this, it would be a different story. You may want to talk with your doc about taking the oxi slow, seeing how you do on it and know his/her views on dose reduction and/or stopping the drug when the neuropathy symptoms become severe. Before starting, sit down with the onc and get very specific with him/her. Ask questions about what he/she considers severe with respect to the side effects - such as - how long the neuropathy symptoms should last between cycles, how quickly the symptoms show up and where they are on the body. For example, neuropathy symptoms that show up immediately in the facial area (exluding the throat) are generally NOT considered normal and require a dose reduction immediately. I had symptoms after one dose which my onc said would be normal for a person after 8 - 10 doses and my oxi was discontinued immediately. Pin your onc down on his/her opinions about this. Ask all sorts of questions and write things down.
