<qa>  What is the purpose of the multicenter phase II trial?Our aim is to conducted a multicenter phase II trial of the cisplatin-oral vinorelbine -radiotherapy combination after induction chemotherapy with cisplatin-docetaxel in patient with NSCLC. Oral vinorelbine will be used in the present study rather than the intravenous form because: 1- Previous investigations have demonstrated that oral vinorelbine is as effective as the intravenous form in the treatment of NSCLC. 2 - We think that the use of oral agents in CT will reduce some disagreements provoked by intravenous injections: stress, infections, hemorrhage, displacement at the hospital and cost of CT.
