Conformal radiotherapy for brain tumors.

The technical improvements of three-dimensional conformal radiotherapy can decrease the toxicity of brain treatment to acceptable levels. The adoption of the technique by more centers would allow for the potential advantages of three-dimensional radiotherapy to be employed in a greater number of patients. Further studies evaluating the use of three-dimensional conformal radiotherapy in patients with nervous system neoplasms should focus on determining the effects on quality of life for the patient and survival compared with more standard treatment techniques.
