My husband was also told to have 3 additional chemo after completing his 3 rounds of cisplastin and 39 rads. He had a horrible time. they gave him a month off and wanted to do the 5FU I asked for an alternative and they said he could do carbo/taxol for 3 rounds- 3 weeks apart. I asked what the outcome would be. They really didn't have any numbers but the MO told us something like if 100 people take these extra 3 treatments 25 mite not have a reaccurence.(notice the word mite) Well thoes numbers did not impress my husband since he had such a hard time so far through the treatments. So he agreed to try one which we did on 6/11. He was still so sick from it. So now he has opted to not take the last two. So that is were we are now. This is a long and slow process. He just wants to get his strength back. Good luck to you.
