background: central nervous system (cns) relapse in acute lymphoblastic leukemia was significantly decreased due to the use of new chemotherapyeutic agents, intrathecal chemotherapy and cranial irradiation. the purpose of this study was to compare the effectiveness of intrathecal (it) cns chemotherapy alone versus combination of it chemotherapy with cranial irradiation for prevention of cns rel...

Introduction: Ionizing radiation is non-surgical treatment of brain tumors and metastases. Preclinical studies have showed main insights into harmful effects of radiation on the nervous system in vivo and in vitro. Cognitive impairment such as progressive memory, executive and attention performance deficits indicates a significant risk for patients experiencing conventional rad...
Prophylactic cranial irradiation (PCI) is being reintroduced into multimodality treatment protocols of patients with small-cell lung cancer (SCLC). The history of its use brings interesting insights into clinical evaluations of treatment strategies and design of relevant and informative trials. The critical issues of effectiveness and overall health gains of prophylactic cranial irradiation hav...
objective: ocular morbidity is widely observed when radiotherapy includes the orbit. oxidative stress generated by irradiation is responsible for this complication. in different studies, it has been shown that melatonin has antioxidative properties and a radioprotective role. the aim of this study was to evaluate the antioxidant role of melatonin against radiation-induced oxidative injury in ra...
The case of a middle aged man who developed a meningioma directly underneath the site of a naevus treated with radiotherapy as a child, is presented. Epidemiological evidence and reports of similar cases suggesting meningiomas may be a sequel to irradiation, are reviewed.
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...
Cranial irradiation in children and adults often results in irreversible hypopituitarism. The earliest and most common endocrine abnormality is GH deficiency, often followed by other pituitary hormone deficits. We investigated whether a similar pattern of progressive hypopituitarism could be reproduced in an animal model. Different doses of cranial irradiation were delivered to the hypothalamo-...
