Second-line treatment of stage III/IV non-small-cell lung cancer (NSCLC) with pemetrexed in routine clinical practice: evaluation of performance status and health-related quality of life.

ABSTRACT: Second-line treatment of advanced non-small-cell lung cancer (NSCLC) improves overall survival. There is a lack of data regarding the impact on patients' overall health condition. This prospective, non-interventional study evaluated performance status (PS) and health-related quality of life (HR-QoL) during second-line pemetrexed treatment in routine clinical practice.Stage III/IV NSCLC patients who initiated second-line pemetrexed (standard vitamin and dexamethasone supplementation) were observed for a maximum of 9 treatment cycles. The primary objective was to evaluate the proportion of patients achieving improvement of Karnofsky Index (KI) of ? 10% (absolute) or maintaining KI ? 80% after the second treatment cycle ("KI benefit response"). HR-QoL was self-rated using the EuroQoL-5D questionnaire (EQ-5D). Factors potentially associated with KI benefit response were evaluated using logistic regression models.Of 521 eligible patients (73.5% Stage IV, median age 66.3 yrs, 36.1% ? 70 yrs, 62.0% with KI ? 80%), 471 (90.4%) completed at least 2 treatment cycles. 58.0% (95%CI 53.6%;62.2%) achieved KI benefit response after the second cycle. Patients with baseline KI ? 80%, no Grade 3/4 toxicities during the first 2 cycles, or combination regimen as prior first-line therapy were more likely to achieve a KI benefit response. EQ-5D scores improved over time. Grade 3/4 toxicities were reported in 23.8% of patients (mainly fatigue/asthenia 15.9%, neutropenia 8.7%).In this large prospective, non-interventional study of second-line pemetrexed treatment in patients with advanced NSCLC, including 36% elderly patients ( ? 70 years), physician-rated PS and self-rated HR-QoL were maintained or improved in the majority of patients.Registered on ClinicalTrials.gov (NCT00540241) on October 4, 2007.
