Prophylactic Cranial Irradiation for Extensive Small-Cell Lung Cancer.
Small-cell lung cancer (SCLC) has a high predilection for metastasizing to the brain after chemotherapy. This has been blamed on the blood-brain barrier, which prevents chemotherapy from penetrating into the brain, thus creating a sanctuary site. It has been estimated that up to three quarters of patients with SCLC will eventually develop brain metastases. This led investigators to administer p...
متن کاملProphylactic Cranial Irradiation for Extensive-Stage Small Cell Lung Cancer.
abtract Purpose Extensive-stage small-cell lung cancer (esSCLC) is an incurable disease and represents a therapeutic challenge because of its poor prognosis. Studies in prophylactic cranial irradiation (PCI) in esSCLC have shown a decreased incidence of symptomatic brain metastases in patients who respond to systemic chemotherapy. However, its effect on overall survival is debatable. We evaluat...

متن کاملProphylactic cranial irradiation in small cell lung cancer.
The Brain is one of the common relapse sites in small cell lung cancer because of isolation from chemotherapeutic agents by the blood-brain barrier. Prophylactic cranial irradiation (PCI) is expected to reduce brain relapse and increase the survival rate. PCI prolonged the survival in only 10-20% of patients with small cell lung cancer after complete response. Most randomized trials demonstrate...
متن کاملProphylactic cranial irradiation for patients with small-cell lung cancer in complete remission. Prophylactic Cranial Irradiation Overview Collaborative Group.
BACKGROUND Prophylactic cranial irradiation reduces the incidence of brain metastasis in patients with small-cell lung cancer. Whether this treatment, when given to patients in complete remission, improves survival is not known. We performed a meta-analysis to determine whether prophylactic cranial irradiation prolongs survival. METHODS We analyzed individual data on 987 patients with small-c...
