Concurrent versus sequential chemoradiotherapy with cisplatin and vinorelbine in locally advanced non-small cell lung cancer: a randomized study
Abstract
Purpose: The superiority of chemoradiotherapy (CRT) over radiation atone in locally advanced non-small cell lung cancer (NSCLC) has been proven, but the relative merits of a concurrent schedule versus their sequential administration are less clear. This study compared the safety and efficacy of concurrent and sequential CRT, with chemotherapy (CT) consisting of a cisplatin and vinorelbine regimen, in patients with locally advanced NSCLC.
Patients and methods: One hundred and two previously untreated patients (aged 42-75 years) with locally advanced, stage IIIA (n = 15) or stage IIIB (n = 87) NSCLC were entered into the study. The CT schedule consisted of up to four cycles of cisplatin 80 mg/m(2) on day 1, and vinorelbine 25 mg/m(2) at the first and fourth cycles (12.5 mg/m(2) during the 2nd/3rd cycles) on days 1, 8, 15 of a 28-day cycle.
Conclusion: In this study population, concurrent CRT demonstrated significant benefit in terms of response rate, overall survival and time to progression over sequential CRT. The concurrent CRT schedule was associated with higher toxicity; however, the adverse event profile was acceptable in both arms Anglická klíčová slova: concurrent chemoradiotherapy; sequential chemoradiotherapy; locally advanced non-small cell lung cancer; cisplatin; vinorelbine
