Objective: To evaluate the activity and safety of concurrent thoracic radiotherapy (TRT) plus weekly paclitaxel/carboplatin (PC) regimen compared with widely used cisplatin/etoposide (PE) regimen in patients with unresectable stage III non-small cell lung cancer (NSCLC). Patients and methods: Patients were randomly assigned to receive the following treatments: PE arm, cisplatin (50mg/m 2) on days 1, 8, 29, and 36 and etoposide (50mg/m 2) on days 1-5 and 29-33 plus 60Gy of TRT; PC arm, weekly concurrent carboplatin (AUC=2) and paclitaxel (45mg/m 2) plus 60Gy of TRT. Results: A total of 65 patients were randomized (PE arm, n= 33; PC arm, n= 32). The 3-year overall survival (OS) was significantly better in the PE arm than in the PC arm (33.1% vs. 13%, P= .04). The incidence of Grade 3/4 neutropenia was 78.1% in the PE arm and 51.5% in the PC arm (P= .05). The rate of Grade 2 or greater radiation pneumonitis was 25% in the PE arm and 48.5% in the PC arm (P= .09). Conclusions: Compared to PE regimen, weekly PC regimen cannot be recommended since it failed to achieve an improvement in either OS or PFS. © 2012 Elsevier Ireland Ltd.
