I go thro' the same, start with carbo/taxol and follow by tarceva .
When tarceva not working, been given many options of chemo drug combination, but, most of the oncology I visited suggest for me to use cisplatin + alimta .
meantime, was infomed alimta can also be use alone as maintenance drug.
as for Avastin, it's recommended by oncology to use it together with carbo/taxol . also been advise that for patient with bleeding is not advisable .
