Description
This is a prospective Phase II study. The purpose of this study is to monitor the side effects and treatment outcomes of delivering higher doses of radiation therapy to the tumour, while limiting the dose of radiation to the normal tissues. This will be done using a 5 day treatment schedule.
The characteristics of patients whose disease remains confined to limited areas in the long term, compared with those who do not will also be described.
