Eppie,
I'm wondering why they staged him at IIIb at diagnosis? Is it because he had the nodules in both lungs? I may have missed this info in a previous post, sorry.
Is his pleural effusion malignant? If not, then his stage may not be IIIb. I was diagnosed with a primary tumor in my right lung and a malignant pleural effusion 2 1/2 years ago. I'm still here and doing pretty well.
If he is truly at stage IIIb and they are treating him with Taxol/Carbo, then he is getting systemic chemo, meaning it is attacking any cancer cells that may be around in any part of the body. In fact, my doctor says they prefer not to do PET scans at my stage (which is now stage IV) because it would not change the course of treatment.
I think your dad will do well, he sounds like he is very strong, and has you giving him great support.
