The effect of Tarceva on overall survival was similar in patients with a baseline performance status (ECOG) of 2-3 (HR = 0.77, CI 0.6-1.0) or 0-1 (HR = 0.73, 0.6-0.9), male (HR = 0.76, CI 0.6-0.9) or female patients (HR = 0.80, CI 0.6-1.1), patients < 65 years of age (HR = 0.75, CI 0.6-0.9) or older patients (HR = 0.79, CI 0.6-1.0), patients with one prior regimen (HR = 0.76, CI 0.6-1.0) or more than one prior regimen (HR = 0.75, CI 0.6-1.0), Caucasian (HR = 0.79, CI 0.6-1.0) or Asian patients (HR = 0.61, 0.4-1.0), patients with adenocarcinoma (HR = 0.71, CI 0.6-0.9) or squamous cell carcinoma (HR = 0.67, CI 0.5-0.9), but not in patients with other histologies (HR 1.04, CI 0.7-1.5), patients with stage IV disease at diagnosis (HR = 0.92, CI 0.7-1.2) or < stage IV disease at diagnosis (HR = 0.65, 0.5-0.8).
