 Prophylactic cranial irradiation

Prophylactic cranial irradiation (PCI) is a preventive radiation therapy used primarily in patients with certain types of cancer, particularly small cell lung cancer (SCLC) and, in some cases, hematologic malignancies such as lymphoma and leukemia. The goal of PCI is to reduce the risk of the cancer spreading to the brain, which can occur in these types of cancers.
