PURPOSE: To investigate the factors that potentially lead to brain radionecrosis after hypofractionated stereotactic radiotherapy targeting the postoperative resection cavity of brain metastases. METHODS AND MATERIALS: A retrospective analysis conducted in two French centres, was performed in patients treated with trifractionated stereotactic radiotherapy (3×7.7Gy prescribed to the 70% isodose line) for resected brain metastases. Patients with previous whole-brain irradiation were excluded of the analysis...

Intracranial metastasis from prostate cancer is rare. As treatment of castration-resistant prostate cancer improves, the incidence of men with intracranial metastasis from prostate cancer is increasing. Radiation therapy for treatment of intracranial metastasis from prostate cancer is systematically reviewed. A comprehensive review examining peer-reviewed, English language articles from 1990 to 2015 was performed on multiple databases, yielding 1274 articles. These articles were reviewed and selected for studies that met the following inclusion criteria: (1) patients with intracranial metastases from prostate cancer; (2) patients underwent radiation therapy as primary or adjuvant therapy; (3) the sample size of patients was larger than 2...

Patients with head and neck malignancies commonly develop metastatic disease, yet rarely do these carcinomas metastasize to the brain. Stereotactic radiosurgery (SRS) is routinely employed to treat brain metastases (BM). This study was undertaken to examine the efficacy of SRS for BM from primary head and neck carcinomas. From 2000 to 2016, a total of 19 patients with 38 lesions were retrospectively identified. All patients presented with a primary head and neck malignancy and subsequently developed metastatic disease to the brain treated with SRS at our institution...

This study shows for the first time that normal brain tissue toxicities after WBI can be reduced with increased dose rate. Spatial memory is preserved after WBI with mean dose rates above 100Gy/s, whereas 10Gy WBI at a conventional radiotherapy dose rate (0.1Gy/s) totally impairs spatial memory.

Leptomeningeal metastases (LM) are found in approximately 3.8% of non-small cell lung cancer cases with an increased incidence in adenocarcinoma, and approximately one-third of patients will present with concomitant brain metastases. We report the case of a 50-year-old male patient with stage IV exon 19-del-EGFR mutant lung adenocarcinoma who progressed on second-generation TKI therapy with manifestation of symptomatic simultaneous diffuse brain and LM. Whole-brain radiotherapy with concurrent afatinib resulted in an almost complete regression of neurological symptoms as well as good, durable radiological response...

BACKGROUND: There is limited data on the efficacy of anti-programmed death 1 (PD-1) antibodies in patients (pts) with melanoma brain metastasis (BM), particularly those which are symptomatic. METHOD: We retrospectively assessed pts with melanoma BM treated with PD-1 antibodies, nivolumab and pembrolizumab. Clinicopathologic and treatment parameters were collected and outcomes determined for intracranial (IC) response rate (RR) using a modified RECIST criteria, with up to five IC target lesions used to determine IC response, disease control rate (DCR) and progression-free survival (PFS)...

Clinical Question: Is up-front whole-brain radiotherapy required to treat multiple brain metastases from non-small-cell lung cancer when highly active targeted therapies are available? Clinical Application: Patients with EGFR-mutant or ALK-positive non-small-cell lung cancer with brain metastases now have the potential to achieve a prolonged survival. Through use of highly active targeted therapies, whole-brain radiotherapy can be safely postponed, diminishing toxic effects that could impair quality of life...

Didier Wion
Surgery precedes both radiotherapy and chemotherapy as the first-line therapy for glioma. However, despite multimodal treatment, most glioma patients die from local recurrence in the resection margin. Glioma surgery is inherently lesional, and the response of brain tissue to surgery includes hemostasis, angiogenesis, reactive gliosis and inflammation. Unfortunately, these processes are also associated with tumorigenic side-effects. An increasing amount of evidence indicates that the response to a surgery-related brain injury is hijacked by residual glioma cells and participates in the local regeneration of tumor tissues at the resection margin...

PURPOSE: Prior studies suggest a high incidence of leptomeningeal failure (LMF) in breast cancer metastatic to brain. This study examines breast cancer-specific variables affecting development of LMF and survival after Gamma-Knife Radiosurgery (GKS). METHODS: Between 2000-2010, 149 (breast) and 658 other-histology patients were treated with GKS. Hormone/HER2, age, local/distant brain failure, prior craniotomy, and prior whole-brain radiotherapy (WBRT) were assessed...

Purpose: This study investigates the feasibility of personalizing radiotherapy prescription schemes (treatment margins and fractional doses) for glioblastoma (GBM) patients and their potential benefits using a proliferation and invasion (PI) glioma model on phantoms. Methods and Materials: We propose a strategy to personalize radiotherapy prescription schemes by simulating the proliferation and invasion of the tumor in 2D according to the PI glioma model. We demonstrate the strategy and its potential benefits by presenting virtual cases, where the standard and personalized prescriptions were applied to the tumor...

INTRODUCTION: Survival after a diagnosis of brain metastasis in non-small-cell lung cancer (nsclc) is generally poor. We previously reported a median survival of approximately 4 months in a cohort of patients treated with whole-brain radiotherapy (wbrt). Since that time, we implemented a program of stereotactic radiosurgery (srs). In the present study, we examined survival and prognostic factors in a consecutive cohort of patients after the introduction of the srs program. METHODS: Data from a retrospective review of 167 nsclc patients with brain metastasis referred to a tertiary cancer centre during 2010-2012 were compared with data from a prior cohort of 91 patients treated during 2005-2007 ("pre-srs cohort")...

PURPOSE: Elderly patients make up a large percentage of the individuals newly diagnosed with glioblastoma (gbm), but they face particular challenges in tolerating standard therapy, and compared with younger patients, they experience significantly shorter survival. We set out to compare clinical characteristics, treatment patterns, and outcomes in a non-elderly group (<65 years) and an elderly group (≥65 years) of patients diagnosed with gbm. METHODS: This retrospective population-based study used a province-wide cancer registry to identify patients with a new diagnosis of gbm within a 6-year period (2006-2012)...

Primitive neuroectodermal tumors (PNETs) are highly malignant neoplasms of embryonal origin manifesting in children and adolescents, rarely seen in adults. Carcinoma lung with hemorrhagic metastasis to the brain is very common, but primary lung PNET with hemorrhagic brain metastasis is extremely uncommon. We hereby report a 29-year-old female diagnosed as PNET lung was treated with vincristine, adriamycin, and cyclophosphamide alternating with ifosfamide plus etoposide followed by radiotherapy (RT). After 9 months, she developed hemorrhagic brain metastasis from PNET lung confirmed from tissue immunohistology postcraniotomy...

Leptomeningeal metastases are a late manifestation of systemic cancer which affects up to 10% of patients with solid tumors. Prognosis is poor, and overall survival at 1 year is only approximately 10%. Management depends mainly on general and neurological condition, primary tumor, and patterns of metastasis, notably absence or presence of concurrent systemic or solid brain metastases. Here we set out to characterize current practice patterns of diagnosis and treatment of patients with leptomeningeal metastasis in Europe...

BACKGROUND: Twelve years ago, a randomized trial demonstrated that a radiosurgery boost added to whole-brain radiotherapy (WBRT) improved intracerebral control (IC) in patients with one to three cerebral metastases. Overall survival (OS) was improved only in the subgroup of patients with a single metastasis but not in the entire cohort. The present study compared both regimens in a different scenario outside a randomized trial. METHODS: A total of 252 patients with one to three cerebral metastases were included...

PURPOSE: In the randomized G-PCNSL-SG-1 trial, the addition of whole brain radiotherapy (45 Gy) to high-dose methotrexate (HD-MTX)-based chemotherapy (early WBRT arm) did not prolong overall survival (OS) as compared to HD-MTX-based chemotherapy alone (no early WBRT arm) in primary CNS lymphoma (PCNSL) patients. To determine whether WBRT might lead to quality of life (QoL)-relevant late neurotoxicity, this trial prospectively monitored QoL. METHODS: QoL measurements were performed using the EORTC-QLQ-C30 and BN20 questionnaires and combined with repeated Mini Mental State Examinations (MMSE)...

REVIEW

BACKGROUND: Current treatment guidelines for limited-stage small-cell lung cancer (SCLC) recommend concomitant platinum-based chemo-radiotherapy plus prophylactic cranial irradiation, based on the premise that SCLC disseminates early, and is chemosensitive. However, although there is usually a favourable initial response, relapse is common and the cure rate for limited-stage SCLC remains relatively poor. Some recent clinical practice guidelines have recommended surgery for stage 1 (limited) SCLC followed by adjuvant chemotherapy, but this recommendation is largely based on the findings of observational studies...

Surgery after administering bevacizumab should be carefully considered particularly because of wound healing concerns. A 27-year-old man presented with multiple tumor recurrences after gross total removal of a left temporal oligodendroglioma (1p/19q-noncodeleted). Whole brain radiotherapy with concomitant temozolomide and bevacizumab was immediately prescribed; however, the patient's condition deteriorated because of brain herniation. Three days after administering bevacizumab, an emergency tumor removal with external decompression and a ventriculo-peritoneal shunt was performed...
