Various different dosages of radiation have been assessed and we wish to further investigate this by comparing a less intense schema with a more intense schema. Both of these fall within the range of published experience but have not been directly compared. The more intense schema may have more effect on the tumour but previous variations of dose intensity have not shown significant differences in survival. Differences in control of the metastases in the brain have been suggested but there have been no good comparisons of quality of life. Obviously when survival is measured on average in only 3 to 6 months, this is an important parameter for comparison.
