These results justify the choice of the study design currently suggested, testing the preoperative feasibility
1. chemotherapy: cisplatin-Gemzar (arm A) or
2. chemoradiotherapy: cisplatin-navelbine-radiotherapy (arm B) or Carboplatin-Taxol-radiotherapy (arm C).
The results obtained, in terms of feasibility and toxicity, will make it possible to select the optimal diagrams for a phase III study.
