Elkiesmom -
Your husband's surgery sounds much like mine with a couple of exceptions. My right middle lobe was completely removed and a resection done on the upper lobe (couldn't remove both lobes because of my poor pulmonary function test). My surgeon wanted me to do chemotherapy but my onclogist was not as adamant - thought we could wait it out and do chemo when warranted but gave me the option because he had complete faith in my surgeon. I opted for chemo because my surgeon scared the bejezus out of me. Did it help? I don't know. I was fine for 1 year (plus a few months) but then my CEA kept rising so we knew it was back somewhere (it took 4 Pet Scans and another year to finally find it) and I resumed chemotherapy. I say I don't know if it helped because I might have been OK for that year without chemo - no one knows for sure.
I believe you mentioned carboplatin and taxol - those are pretty mean drugs (I used them as my third line and they did work but I have taken all my oncologist feels comfortable giving). I would ask why the oncologist chose those 2 drugs because there are others that aren't so hard on you - especially if they are saying he is cancer free.
Hope this helps some. Always remember we are the lucky ones - so many people have such advanced cancer when it is found that they can't do surgery.
