Arms of the Study
Arm 1
Experimental
radiotherapy+chemotherapy
Radiotherapy: LEVEL 1: dose given at PTV-G and PTV-C will be 64Gy/32 fractions and 50Gy/25 fractions. LEVEL 2: dose given at PTV-G and PTV-C will be 63Gy/28 fractions and 50.4Gy/28 fractions. LEVEL 3: dose given at PTV-GR (with an integrated boost to the 50% SUVmax area of the primary tumor of the pre-treatment 18FDG-PET/CT scan), PTV-G and PTV-C will be 70Gy/28 fractions, 63Gy/28 fractions and 50.4Gy/28 fractions. LEVEL 4: dose given at PTV-GR (with an integrated boost to the 50% SUVmax area of the primary tumor of the pre-treatment 18FDG-PET/CT scan), PTV-G and PTV-C will be 70Gy/25 fractions, 62.5Gy/25 fractions and 50Gy/25 fractions. Chemotherapy: Concurrent chemotherapy: Cisplatin 25mg/m2 IV daily on Days 1-3 and 29-31 plus 5-FU 500mg/m2 IV continuous infusion over 24 hours daily on Days 1-4 and 29-32. Consolidation chemotherapy: Cisplatin 25mg/m2 IV daily on Days 1-3 plus 5-FU 600mg/m2 IV daily on Days 1-5, cycled every 4 weeks for 2 cycles.
