title: [Optimization of combined radiotherapy and chemotherapy in treatment of non-small cell lung carcinoma].
abstract: OBJECTIVE
  To report the results of CEBI 140 and 142 trials. These trials were aimed at improving the local control in stage III non-small cell carcinoma with concomitant chemotherapy and radiotherapy in the CEBI 140 trial, and with concomitant chemotherapy and radiotherapy followed by local excision in the CEBI 142 trial.
  
  
  METHODS
  Thirty-four patients presenting with stage III non-small cell lung carcinoma were included into the CEBI 140 trial from December 1989 to December 1992. Patients were treated with a combination of daily cisplatin (6 mg/m2 per day, 144 mg/m2 in total), vindesine once a week (2.5 mg/m2, 15 mg/m2 in total) and bifractionated radiotherapy (60 Gy/48 fractions/6 weeks) followed by two cycles of cisplatin 120 mg/m2 (at d18 and d45 after completion of radiochemotherapy) and three cycles of vindesine (6 mg/m2 at d24, d31, and d38 after completion of radiochemotherapy). Twenty-eight patients presenting with stage IIIB non-small cell carcinoma-were included into the CEBI 142 trial since January 1993. Patients received a combination of cisplatin (100 mg/m2 at d1 and d24, 200 mg/m2 in total), vinblastine (4 mg/m2 at d1 and d24, 8 mg/m2 in total), 5-fluorouracil in continuous infusion (1,000 mg/m2 from d1 to d3, and from d24 to 26, 6,000 mg/m2 in total) and bifractionated radiotherapy (two series of 21 Gy/14 fractions/9 days, 11 days apart) followed by a new evaluation and surgical excision.
  
  
  RESULTS
  In the CEBI 140 trial, all patients received a complete course of radiotherapy, but the dose of cisplatin was decreased in 27% of the cases, and the dose of vindesine in 88%. There were two toxicity-related deaths. Three months after completion of the protocol, there were 50% of complete responders. The overall survival rates at 1, 2 and 3 years were 53, 33, and 11%, respectively, and disease-free survival rates 21 11, and 11%, respectively. In the CEBI 142 trial the immediate tolerance was good. Twenty-one patients (75%) underwent surgical resection. Four tumors could not be resected. Resection was histologically incomplete in one case, and complete in the 16 remaining cases. With a median follow-up of 14 months, ten patients were alive and disease-free.
  
  
  CONCLUSIONS
  Preliminary results of the CEBI 142 trial are encouraging. More patients and longer follow-up are needed for definitive conclusion. It would be of interest to implement a randomized trial comparing the CEBI 142 scheme and classical radiation therapy.
