Postoperative external beam radiotherapy was considered the standard adjuvant treatment for patients with glioblastoma multiforme until the advent of using the drug temozolomide (TMZ) in addition to radiotherapy. High-dose volume should be focal, minimizing whole brain irradiation. Modern imaging, using several magnetic resonance sequences, has improved the planning target volume definition. Th...

Radiotherapy is the mainstay of treatment after surgery for high-grade gliomas and is usually well tolerated. Radiation toxicity in the brain is usually classified according to the timing of side effects in relation to treatment, as either acute (during radiotherapy), early delayed (within 12 weeks of radiotherapy) or late delayed (months to years after radiotherapy). We report two cases of you...

Objective: Lung cancer is the most common worldwide and among leading causes of death. The aim this study to examine survival patients who received radiotherapy for brain metastases, whose primary non-small cell lung cancer, also determine factors that are like affect results in these as well. Materials Methods: This included 99 with cancer. All metastases radiotherapy. were grouped compared ac...

Diffuse intrinsic pontine glioma (DIPG) kills more children than any other type of brain tumor. Despite clinical trials testing many chemotherapeutic agents, palliative radiotherapy remains the standard treatment. Here, we utilized Cre/loxP technology to show that deleting Ataxia telangiectasia mutated (Atm) in primary mouse models DIPG can enhance tumor radiosensitivity. Genetic deletion Atm i...

AIM OF THE STUDY To evaluate the feasibility of whole-brain radiotherapy (WBRT) with a simultaneous integrated boost (SIB) by forward intensity-modulated radiation therapy (IMRT) in patients with 1-3 brain metastases. MATERIAL AND METHODS Two forward IMRT plans were implemented among 18 patients. In plan A, the prescribed dose was 30 Gy to the whole brain (PTVWBRT) and 50 Gy to individual bra...

1960 www.thelancet.com Vol 388 October 22, 2016 Radiation oncologists are often challenged because of the paucity of randomised trials supporting their clinical practice. In terms of brain metastases treatment, it should be emphasised that there have been fi ve randomised trials assessing whole brain radiotherapy (WBRT): four studies assessing stereotactic radio therapy with or without WBRT for...

OBJECTIVE To determine whether second whole-brain irradiation is beneficial for patients previously treated with whole-brain irradiation. METHODS A retrospective analysis was done for 31 patients with brain metastases who had undergone re-irradiation. Initial whole-brain irradiation was performed with 30 Gy/10 fractions for 87% of these patients. Whole-brain re-irradiation was performed with ...

BACKGROUND Survival of patients with brain metastasis particularly from historically more radio-resistant malignancies remains dismal. A phase I study of concurrent bortezomib and whole brain radiotherapy was conducted to determine the tolerance and safety of this approach in patients with previously untreated brain metastasis. METHODS A phase I dose escalation study evaluated the safety of b...
