Hi Lisa; If your dad just started avastin, he should give that a chance to work. It has been very effective when used with a platinum based drug such as carboplatin. Also, using gemzar instead of taxotere may be a good idea. The gemzar does not cause much neropathy and some studys show it to be more effective than other combos in late stage nsclc. If the tumor is real big, radiation should help shrink it and provide some relief. Do what Don Wood suggested. Make sure your dad gets lots to drink and at least eats snacks throughout the day.
Getting the chemo and radiation is just part of the battle. He has to eat and drink. I hope your dad gets some room to breathe soon.
