cranial irradiation การใช้

Prior cranial irradiation is the only risk factor that definitely predisposes to brain tumor formation.
Prophylactic cranial irradiation ( PCI ) is a type of radiotherapy to the brain, used to reduce the risk of metastasis.
Radiation therapy is commonly used to treat known tumor occurrence in the brain, either with highly precise stereotactic radiation or therapeutic cranial irradiation.
If complete response to chemotherapy occurs in a subject with SCLC, then prophylactic cranial irradiation ( PCI ) is often used in an attempt to prevent the emergence of brain metastases.
The current generally accepted standard of care for all forms of SCLC is concurrent chemotherapy ( CT ) and thoracic radiation therapy ( TRT ) in LD, and CT only in ED . For complete responders ( patients in whom all evidence of disease disappears ), prophylactic cranial irradiation ( PCI ) is also given.
