Experimental: IMRT
External beam radiation with 6 MV photons will be delivered in 200 cGy daily fractions, 35 fractions over 7 weeks for a total dose of 7000 cGy.

Radiation: IMRT |
- Feasibility of adaptive radiation therapy in the definitive treatment (MLC-based IMRT or helical tomotherapy) [ Time Frame: 7 weeks ]Feasibility is determined by employing weekly 3D onboard imaging for plan re-evaluation and initiation of an adaptive process if the original PTV and/or normal structure goals are compromised.
- Measure additional time required by physician and ancillary staff for the process of adaptive IMRT [ Time Frame: 7 weeks ]Recording on a weekly basis the actual time required for repeat CT imaging, plan re-evaluation, replanning, and repeat physics QA.
- Identify a subset of patients in whom adaptive IMRT would be recommended [ Time Frame: 7 weeks ]
- Measure acute and late toxicity [ Time Frame: Until patient death ]
- Local, regional, and distant recurrence [ Time Frame: Until recurrence ]
