Whole Brain Radiation Using IMRT for Patients With Brain Metastases
Some cancers can spread, or metastasize, to the brain. When they do, treatment often involves
surgery and/or radiation. Optimal treatment of brain metastases would maximize disease
control and minimize toxicity (or side effects), and improve the quality of life of patients.
A common type of radiation used for brain metastases is called whole brain radiation, which
treats not just the cancer that can be seen on scans (i.e., gross disease), but the smaller
sites of cancer that may not be visible (i.e. subclinical disease). Fractionation is used to
describe repetitive treatments in which small doses (fractions) of a total planned dose are
