Primary Objective:

To estimate the overall response rate after neo-adjuvant chemotherapy of Docetaxel 75 mg/m2 in combination with Cisplatin 75 mg/m2 given for 3 cycles, and followed by conventional radiotherapy in UCNT.

Secondary Objectives:

To evaluate:

• The radiological response after chemotherapy and radiotherapy
• The pathological response after chemotherapy by cavum biopsy

To estimate:

• The duration of overall response
• The time to progression (T.T.P)

To analyze:

• The overall survival
• The safety profile
