Kim,
Did you discuss the increase in dosage with your Dr's? I guess, after what you told me, it might be worth a try. After reading all the postings here, even though my cancer is considered stage IV, the only mets since the first tumor was removed have been a return in the one lung and mets to the other lung. I consider myself fortunate. My Dr keeps saying how lycky I am because the Tarceva does not have a high success rate for tumor shrinkage in most people. I will keep you in my prayers, stay in touch.
