This open-label, multi-institution, phase II study evaluated the activity of gefitinib at individually escalated doses up to 750mg to achieve the skin toxicity grade greater than or equal to 2. Patients were started on gefitinib 250mg orally daily for 2 weeks. At 2 weeks, patients were reevaluated and given skin toxicity grade according to the National Cancer Institute Common Toxicity Criteria version 3.0 (CTC 3.0). Patients with grade 2 or greater skin toxicity remained on 250 mg daily; in patients with grade 0-1 skin toxicity the dose was escalated to 500 mg daily and again to 750 mg daily on next evaluation until grade 2 or greater skin toxicity was developed.
