BACKGROUND/AIM: Many patients with brain metastases from melanoma receive whole-brain radiotherapy (WBRT). WBRT-regimens must consider the patient's prognosis in order to deliver the best therapy. PATIENTS AND METHODS: Seven factors were correlated to intracerebral control and survival after WBRT alone in 92 patients with melanoma: WBRT regimen, age at WBRT, gender, Karnofsky performance score (KPS), number of brain lesions, number of extracranial metastatic sites, and time from melanoma diagnosis to WBRT...

BACKGROUND Unequivocal brain radiation-induced parkinsonism has so far been reported in only in two pediatric patients. However, with the rising incidence rates for brain tumors in industrialized countries and the consequential increased exposure to cranial radiotherapy, clinicians might become more exposed to this entity. CASE REPORT Three patients were treated for intraparenchymal brain tumor with resection, chemotherapy, and whole brain radiation. One patient developed leukoencephalopathy and parkinsonism within one year of treatment, one developed it seven years after treatment completion, and one developed dementia, parkinsonism and cerebral infracts 40 years after whole brain radiation...

OBJECTIVE Stereotactic radiosurgery (SRS) without upfront whole-brain radiotherapy (WBRT) has influenced recent treatment recommendations for brain metastasis patients. However, in brain metastasis patients who undergo SRS alone, new brain metastases inevitably appear with relatively high incidences during post-SRS follow-up. However, little is known about the second SRS results. The treatment results of second SRS were retrospectively reviewed, mainly for newly developed or, uncommonly, for recurrent brain metastases in order to reappraise the efficacy of this treatment strategy with a special focus on the maintenance of neurological status and safety...

REVIEW
Julia Carnevale, James L Rubenstein
Primary central nervous system (CNS) lymphoma is a challenging subtypes of aggressive non-Hodgkin lymphoma. Emerging clinical data suggest that optimized outcomes are achieved with dose-intensive CNS-penetrant chemotherapy and avoiding whole brain radiotherapy. Anti-CD20 antibody-based immunotherapy as a component of high-dose methotrexate-based induction programs may contribute to improved outcomes. An accumulation of insights into the molecular and cellular basis of disease pathogenesis is providing a foundation for the generation of molecular tools to facilitate diagnosis as well as a roadmap for integration of targeted therapy within the developing therapeutic armamentarium for this challenging brain tumor...

Radiation-induced brain injury (RBI) is the most serious complication after radiotherapy. However, the etiology of RBI remains elusive. In order to evaluate the effect of X-rays on normal brain tissue, adult male BALB/C mice were subjected to whole-brain exposure with a single dose of 10 Gy or sham radiation. The structure and number of mice brain vessels were investigated 1, 7, 30, 90 and 180 days after irradiation by H&E staining and immune-fluorescence staining. Compared with sham control mice, in addition to morphological changes, a significant reduction of microvascular density was detected in irradiated mice brains...

BACKGROUND: Therapeutic approaches to brain metastases include surgery, whole-brain radiotherapy, stereotactic radiosurgery (SRS), and combination therapy. Recently, postoperative or preoperative SRS draws more attention to reduce postoperative recurrence in brain metastases. The goal of this study is to review surgical outcome of patients who had been treated by SRS, and to discuss the effectiveness of preoperative SRS. METHODS: From 2009 to 2015, 174 patients were treated by SRS for brain metastases, and among these 50 patients underwent surgery...

PURPOSE: Incidence of brain metastasis attributed to breast cancer is increasing and prognosis is poor. It is thought that disseminated dormant cancer cells persist in metastatic organs and may evade treatments, thereby facilitating a mechanism for recurrence. Radiotherapy is used to treat brain metastases clinically, but assessment has been limited to macroscopic tumor volumes detectable by clinical imaging. Here, we use cellular MRI to understand the concurrent responses of metastases and nonproliferative or slowly cycling cancer cells to radiotherapy...

The authors present the history of two patients. The first patient, a 69-year-old woman was diagnosed with locally invasive triple negative breast cancer with pulmonary and cerebral metastases. Complete radiological remission of the clinically asymptomatic cerebral metastases was detected under systemic chemotherapy with carboplatin-docetaxel (75 mg/m(2)). Later, the patient received whole brain radiotherapy and a second line of chemotherapy. The overall survival was 20 months from the diagnosis of cerebral metastases with conservation of partial autonomy...

According to two clinical trials presented at the American Society for Radiation Oncology's 2016 annual meeting, stereotactic radiosurgery following surgical removal of brain metastases decreases the risk of local recurrence and, compared with whole-brain radiotherapy, offers patients a better quality of life. As such, postoperative stereotactic radiosurgery should be considered a new standard of care for patients whose cancer has spread to the brain.

BACKGROUND: Whole brain radiotherapy (WBRT) and stereotactic radiosurgery were frequently used to palliate patients with brain metastases. It remains controversial which modality or combination of therapy is superior especially in the setting of limited number of brain metastases. The availability of newer medical therapy that improves survival highlighted the importance of reducing long term radiation toxicity associated with WBRT. In this study, we aim to demonstrate the hippocampal sparing technique with whole brain and integrated simultaneous boost Materials and Methods: Planning data from 10 patients with 1-5 brain metastases treated with SRS were identified...

OBJECTIVES: Patients with brain metastases from small-cell lung cancer (SCLC) who underwent prior prophylactic cranial irradiation (PCI) are often treated with a second course of whole brain radiation therapy (Re-WBRT) or stereotactic radiosurgery (SRS) for purposes of palliation in symptomatic patients, hope for increased life expectancy or even as an alternative to untolerated steroids. Up to date there is only limited data available regarding the effect of this treatment. This study examines outcomes in patients in a single institution who underwent cerebral re-irradiation after prior PCI...
