Chetan,
I am one of the few you will talk to, apparently, who got along worse with chemo than radiation, at least until the last few days of radiation. Yes, I had microscopic extra capsular extension. It was the correct treatment, I believe. After a chemo weekend (I had them on Friday evenings) I would say that I hoped any cancer remaining following my surgery would have as bad a time with Cisplatin as what I was having! They like using chemo with rad because in general it does raise statistics for beating your cancer.

But extra capsular extension is not the only good reason to have chemo. Multiple lymph nodes involved, perineural involvement, and location of the lymph nodes all figure into it as well. If your cancer is more aggressive and less than well differentiated, then chemo is probably going to be valuable because chemotherapy will kill those more aggressive cancers better than the less aggressive ones. This is what the MO told me, and I have read this also.

Hope this helps you.
Best,
Anne
