Popis: BACKGROUND: Patients with advanced non–small-cell lung cancer (NSCLC) and poor performance status (PS) are often excluded from trials. Gefitinib is a safe oral agent that may benefit these patients. PATIENTS AND METHODS: Seventy-two patients with poor PS and advanced NSCLC were enrolled onto this study of gefitinib 250 mg per day given orally until disease progression, with evaluation at 8 weeks. Eligible patients had no previous chemotherapy, an Eastern Cooperative Oncology Group PS of 2/3, and stage IIIB/IV NSCLC. Quality of life (QOL) and symptom response (SR) scores were calculated using the Functional Assessment of Cancer–Lung questionnaire. Patient characteristics included a median age of 75 years; PS of 2/3; and bronchoalveolar (n = 3), adenocarcinoma (n = 29), squamous cell (n = 21), large-cell (n = 11), and unspecified histology (n = 6). Mean treatment duration was 4 months (range, 3 days to 18 months), and median duration of follow-up was 12 months. Grade 3/4 toxicities included rash and diarrhea. RESULTS: Among 70 patients assessed for response, there were 3 partial responses (4%), 32 patients with stable disease (46%), and 18 with progressive disease (26%). Median progression-free survival (PFS) and overall survival (OS) were 3.7 months and 6.3 months, respectively. Six-month and 1-year PFS and OS rates were 35% and 21% and 50% and 24%, respectively. Eighty-two percent and 48% of patients reported improvements or no change in QOL and SR, respectively. CONCLUSION: Gefitinib demonstrates modest efficacy and is well tolerated as initial therapy in advanced NSCLC for patients with poor PS.
