OBJECTIVE This is the final report of a phase III randomized study to evaluate whole-brain radiotherapy (WBRT) in primary therapy of primary CNS lymphoma (PCNSL) after a median follow-up of 81.2 months. METHODS Patients with newly diagnosed PCNSL were randomized to high-dose methotrexate (HDMTX)-based chemotherapy alone or followed by WBRT. We hypothesized that the omission of WBRT would not ...

BACKGROUND Brain metastases occur in up to 40% of all patients with systemic cancer. We aimed to assess whether stereotactic radiosurgery provided any therapeutic benefit in a randomised multi-institutional trial directed by the Radiation Therapy Oncology Group (RTOG). METHODS Patients with one to three newly diagnosed brain metastases were randomly allocated either whole brain radiation ther...

INTRODUCTION We report our series of patients with large brain metastases, >3 cm in diameter, who received stereotactic radiosurgery (SRS) as a component of their treatment, focusing on survival and intracranial recurrence rates. MATERIALS AND METHODS The brain tumor database was queried for patients treated with SRS for large brain metastases. Local recurrence (LR) and distant brain recurren...

PURPOSE To audit outcomes after introducing frameless stereotactic radiosurgery (SRS) for brain metastases, including co-interventions: neurosurgery, systemic therapy, and whole brain radiotherapy (WBRT). We report median overall survival (MS), local failure, and distant brain failure. We hypothesized patients treated with SRS would have clinically meaningful improved MS compared with historic ...

BACKGROUND Brain metastases of gastrointestinal origin are a rare occurrence. Radiation therapy (RT) in the form of stereotactic radiosurgery (SRS) or whole brain radiation therapy (WBRT) is an effective established treatment modality in either the definitive or adjuvant setting. The aim of this study is to assess the long-term clinical outcomes of patients with gastrointestinal (GI) brain meta...

Our objectives were to (1) investigate the feasibility of the use of the Japanese version of the Hopkins Verbal Learning Test-Revised (HVLT-R); (2) identify the clinical factors influencing the HVLT-R scores of patients undergoing whole-brain radiation therapy (WBRT); and (3) compare the neurocognitive function (NCF) after WBRT in different dose fractionation schedules. We administered the HVLT...

Primary central nervous cell lymphoma (PCNSL) is an uncommon neoplasm of the brain, leptomeninges, and rarely the spinal cord. Initially thought to be characteristically associated with congenital, iatrogenic, or acquired immunosuppression, PCNSL is now recognized with increasing frequency in immunocompetent individuals. The role of surgery is limited to establishing diagnosis, as PCNSL is ofte...

Mild cognitive impairment is a well-documented consequence of whole brain radiation therapy (WBRT) that affects 40-50% of long-term brain tumor survivors. The exact mechanisms for the decline in cognitive function after WBRT remain elusive and no treatment or preventative measures are available for use in the clinic. Here, we review recent findings indicating how changes in the neurovascular un...

To estimate the value of whole brain radiotherapy (WBRT) in the treatment of primary CNS lymphoma (PCNSL), it is important to recall the goals of treatment when confronted with this disease. Presumably, our goals of PCNSL treatment are to improve neurological deficits, improve or maintain quality of life, delay neurological progression, prolong progression-free survival, prolong overall surviva...

BACKGROUND Whole brain radiotherapy (WBRT) is a vital tool in radiation oncology and beyond, but it can result in adverse health effects such as neurocognitive decline. Hippocampal Avoidance WBRT (HA-WBRT) is a strategy that aims to mitigate the neuro-cognitive side effects of whole brain radiotherapy treatment by sparing the hippocampi while delivering the prescribed dose to the rest of the br...
