PURPOSE Volumetric modulated arc therapy (VMAT) can deliver intensity modulated radiotherapy (IMRT) like dose distributions in a short time; this allows the expansion of IMRT treatments to palliative situations like brain metastases (BMs). VMAT can deliver whole brain radiotherapy (WBRT) with hippocampal avoidance and a simultaneous integrated boost (SIB) to achieve stereotactic radiotherapy (S...

Background: Whole-brain radiation therapy (WBRT) with hippocampus sparing (HS) has been investigated by the radiation oncology working group (RTOG) 0933 trial for patients with multiple brain metastases. They showed a decrease of adverse neurocognitive effects with HS WBRT compared to WBRT alone. With the development of automated treatment planning system (aTPS) in the last years, a standardiza...

abstract: gestational trophoblastic neoplasm (gtn) is among rare human tumors which can be observed with widespread metastasis. two young patients with emergent neurologic symptoms with no gynecological problems are presented in this report. gtn was later diagnosed in both cases with brain metastasis. the first case: a 22 years old patient, admitted to the infectious disease ward, with probable...

BACKGROUND Whole-brain radiation therapy (WBRT) with hippocampus sparing (HS) has been investigated by the radiation oncology working group (RTOG) 0933 trial for patients with multiple brain metastases.

BACKGROUND Whole brain radiotherapy (WBRT) plus sequential focal radiation boost is a commonly used therapeutic strategy for patients with brain metastases. However, recent reports on WBRT plus simultaneous in-field boost (SIB) also showed promising outcomes. The objective of present study is to retrospectively evaluate the efficacy and toxicities of WBRT plus SIB with image guided intensity-mo...

PURPOSE Many patients treated with stereotactic radiosurgery (SRS) alone as initial treatment require 1 or more subsequent salvage therapies. This study aimed to determine if commonly used salvage strategies are associated with differing risks of radiation necrosis (RN). METHODS AND MATERIALS All patients treated with upfront SRS alone for brain metastases at our institution were retrospectiv...

Purpose To compare Whole-brain radiation therapy with simultaneous integrated boost (WBRT+SIB) to stereotactic radiosurgery (SRS)for non-small cell lung cancer (NSCLC)with brain metastases (BMs)in terms of overall survival (OS), intracranial progression-free-survival(iPFS), toxicity and objective response rate (ORR) Methods A retrospective review was performed in our hospital 90 patients diagno...

The team of Brown et al. are to be congratulated for the recent publication of a prospective randomized trial that evaluated cognitive function and tumor control in patients with 1–3 brain metastases (primarily lung).[1] This level 1 evidence provided additional confirmatory support regarding the role of stereotactic radiosurgery (SRS) as a primary management option for patients whose cancer ha...

BACKGROUND Radiotherapy for patients suffering from malignant neoplasms has developed greatly during the past decades. Stereotactic radiosurgery (SRS) is one important radiotherapeutic option which is defined by a single and highly focussed application of radiation during a specified time interval. One of its important indications is the treatment of brain metastases. OBJECTIVES The objective...

Abstract Recent advances to preserve neurocognitive function in patients treated for brain metastases include stereotactic radiosurgery (SRS), hippocampal avoidance whole radiation therapy (HA-WBRT), and memantine administration. The hippocampus, corpus callosum, fornix, amygdala are key substructures with a low propensity metastases. Herein, we report our preliminary experience using “memory-a...
