In brief: Only if ..
Gefitinib will only work if there is a egfr mutation detected on the cancer.
It will not be effective if there is no egfr mutation detected.

And it is likely to be equi-effective as erlotinib in similar populations,

In brief: Not used
Really not used anymore since the company sponsored trial showed no benefit.
Now tarceva (erlotinib) has essentially replaced iressa (gefitinib). If patients have a mutation in egfr (not kras), probably better than chemotherapy. There was a trial that did show a benefit after chemotherapy in patients with a mutation. Hope this helps.
