PRIMARY OBJECTIVES:
I. To determine the accuracy of dose delivery and patient comfort with treatment time.
II. To evaluate normal tissue dose volume statistics and compare to standard planning.
OUTLINE:
Patients undergo 4pi radiation simulation and planning followed by 5 to 10 daily fractions of 4pi palliative radiotherapy. If an acceptable plan cannot be achieved using 4pi planning, then the patient will be treated with standard radiation therapy planning for palliative re-irradiation.
After completion of study treatment, patients are followed up at 6 weeks.
