Purpose This is a phase II, multicenter, open-label study of chemotherapy-naive patients with non-small-cell lung cancer (NSCLC) and age >= 70 years who were treated with erlotinib and evaluated to determine the median, 1-year, and 2-year Survival. The secondary end points include radiographic response rate, time to progression (TTP), toxicity, and symptom improvement. Patients and Methods Eligible patients with NSCLC were treated with erlotinib 150 mg/d until disease progression or significant toxicity. Tumor response was assessed every 8 weeks by computed tomography scan using Response Evaluation Criteria in Solid Tumors. Tumor samples were analyzed for the presence of somatic mutations in EGFR and KRAS. Results Eighty eligible patients initiated erlotinib therapy between March 2003 and May 2005. There were eight partial responses (10%), and an additional 33 patients (41%) had stable disease for 2 months or longer. The median TTP was 3.5 months (95% Cl, 2.0 to 5.5 months). The median survival time was 10.9 months (95% Cl, 7.8 to 14.6 months). The 1- and 2- year survival rates were 46% and 19%, respectively. The most common toxicities were acneiform rash (79%) and diarrhea (69%). Four patients developed interstitial lung disease of grade 3 or higher, with one treatment-related death. EGFR mutations were detected in nine of 43 patients studied. The presence of an EGFR mutation was strongly correlated with disease control, prolonged TTP, and survival. Conclusion Erlotinib monotherapy is active and relatively well tolerated in chemotherapy-naive elderly patients with advanced NSCLC. Erlotinib merits consideration for further investigation as a first-line therapeutic option in elderly patients.
