Background: Platinum-based chemotherapy represents the standard of care for advanced non-small cell lung cancer (NSCLC) while non-platinum-based regimens are frequently administered in patients with relapse. A retrospective analysis of the sequence administration of these regimens in the first- and second-line setting was performed. Patients and Methods: The records of patients enrolled in the Hellenic Oncology Research Groups's randomized advanced NSCLC trials from February 1997 to September 2006 were retrospectively reviewed. The efficacy of non-platinum-based chemotherapy administered as first- or second-line treatment (n=94, cohort A) was compared to that of non-platinum-based first-line followed by platinum-based second-line chemotherapy (n=267, cohort B), and the reverse sequence (n=123, cohort C). Results: The objective response rate (ORR) to first-line chemotherapy was higher in cohort C compared to cohort A (45.5% vs. 25.5%, respectively, p=0.002) and cohort B (45.5% vs. 21.3%, p=0.0001). The ORR to second-line therapy was 17%, 13.1% (p=0.349) and 7.3% (p=0.027) in cohorts A, B and C, respectively. Time to progression and the overall survival were comparable among the three cohorts in both first- and second line therapy. Conclusion: Platinum-based first-line chemotherapy improved response rate compared to non-platinum-based regimens; however, the overall survival was comparable, irrespective of the sequence administration of these regimens is the first- and second-line setting.
