MO25.04 - Phase II study comparing Cisplatin/Etoposide and weekly Paclitaxol/Carboplatin regimens with concurrent thoracic radiotherapy in patients with locally advanced non-small cell lung cancer (ID 67)
10:30 - 12:00 | Author(s): J. Liang
To evaluate the effect and safety of concurrent thoracic radiotherapy (TRT) with Cisplatin/Etoposide (PE) compared with weekly Paclitaxol/Carboplatin (PC) regimens in patients with stage III non-small cell lung cancer (NSCLC).
Patients with stage III NSCLC were randomly assigned to receive PE regimen (PE arm) cisplatin 50mg/m d1, 8, 29 and 36, etoposide 50mg/m d1-5 and 29-33 concurrent with TRT 60Gy, or PC regimen (PC arm) carboplatin (AUC=2) and paclitaxol 45mg/m concurrent with TRT 60Gy.
156 patients were registered. Eventually, 149 were assigned to PE arm (73) and PC (76). The median follow-up time was 38 months. The median survival time (MST) was 20 months. The 2-year overall survival (OS) and 3-year OS were 39.8% and 32.9%. The 2-year progress free survival (PFS) and 3-year PFS were 24.8% and 22.4%. The MST of PE arm and PC arm were 22 months and 20 months, and the median progress free time were 13 months and 11months, respectively. The 2-year OS of PE arm and PC arm were 44.9% and 35%, the 3-year OS were 40% and 26.2% (p=0.323), respectively. The 2-year PFS of PE arm and PC arm were 27.7% and 22.1%, 3-year PFS were 24.5% and 20.5% (p=0.449), respectively. The incidence of Great 3/4 bone marrow depression of PE arm and PC arm were 34.2% and 23.7% (p=0.29). The incidence of Great 2 or greater radiation pneumonitis of PE arm and PC arm were 19.2% and 26.3% (p=0.059).
For stage III NSCLC, concurrent TRT with PE regimen has improved PFS and OS comparing with PC regimen without significant difference. Concurrent PE regimen has a lower incidence of Great 2 or greater radiation pneumonitis.
