A woman aged 35 years was diagnosed with triple-negative breast cancer in October 2012. During the investigation, it was discovered that she was pregnant, the patient decided to have an abortion. She was submitted to a radical modified mastectomy and adjuvant chemotherapy followed by adjuvant breast radiotherapy of the left breast. 2 months after the adjuvant treatment, she began to have headaches and dizziness. The cranial MRI (head MRI) showed brain metastasis. She was then treated with whole brain radiotherapy, stereotactic radiosurgery and concomitant temozolomide which resulted in complete response...

BACKGROUND: Arteriovenous malformations (AVMs) can underlie many diverse neurological signs and symptoms. Headaches are a common presentation that can have a significant impact on quality of life. OBJECTIVE: The authors investigated Gamma Knife(®) stereotactic radiosurgery (SRS) outcomes in patients with AVMs and associated headaches. METHODS: This retrospective study analyzed 102 patients with AVMs who underwent SRS between 1995 and 2013...

REVIEW
Monica Livia Gheorghiu
Purpose Treatment of acromegaly has undergone important progress in the last 20 years mainly due to the development of new medical options and advances in surgical techniques. Pituitary surgery is usually first-line therapy, and medical treatment is indicated for persistent disease, while radiation (RT) is often used as third-line therapy. The benefits of RT (tumor volume control and decreased hormonal secretion) are hampered by the long latency of the effect and the high risk of adverse effects. Stereotactic RT methods have been developed with the aim to provide more precise targeting of the tumor with better control of the radiation dose received by the adjacent brain structures...

OBJECTIVE: The objective of this study was to determine the use of 3D printed model of an eye with intraocular tumor for linear accelerator-based stereotactic radiosurgery. METHODS: The software for segmentation (3D Slicer) created virtual 3D model of eye globe with tumorous mass based on tissue density from computed tomography and magnetic resonance imaging data. A virtual model was then processed in the slicing software (Simplify3D(®)) and printed on 3D printer using fused deposition modeling technology...

Juvenile angiofibroma is an uncommon, benign, locally aggressive vascular tumor. It is found almost exclusively in young men. Common presenting symptoms include nasal obstruction and epistaxis. More advanced tumors may present with facial swelling and visual or neurological disturbances. The evaluation of patients with juvenile angiofibroma relies on diagnostic imaging. Preoperative biopsy is not recommended. The mainstay of treatment is resection combined with preoperative embolization. Endoscopic surgery is the approach of choice in early stages, whereas, in advanced stages, open or endoscopic approaches are feasible in expert hands...

BACKGROUND: The current study was conducted to investigate survival and the response to radiotherapy among patients with molecular subtypes of breast cancer brain metastases treated with or without targeted therapies. METHODS: Patients diagnosed with breast cancer brain metastases at a single tertiary care institution were included. The primary outcome was overall survival, whereas secondary outcomes included the cumulative incidences of distant intracranial failure, local failure, and radiation necrosis...

OBJECTIVE(S): To investigate the efficacy of immune checkpoint therapy (ICT) administered with stereotactic radiosurgery (SRS) and determine the effects of relative treatment timing on lesion response. METHODS: A prospective institutional database of all patients with intact brain metastases treated with SRS from 2007 to 2015 was reviewed for patients diagnosed with malignant melanoma. Lesion response was determined using a modified RECIST v1.1 criteria. Patients were grouped according to if they received ICT and the timing of ICT relative to SRS...

BACKGROUND: Published guidelines regarding the optimal treatment strategies for brain metastases focus on patients with ≤3 lesions. As delivery techniques for stereotactic radiosurgery (SRS) improve, radiation oncologists are increasingly using it for patients with >3 metastases. In the current study, the authors sought to characterize practice patterns among practitioners to identify areas of controversy. METHODS: A survey of practicing radiation oncologists was distributed via e-mail...

BACKGROUND: Glioblastoma multiforme (GBM) carries a poor prognosis with high recurrence rates. Salvage stereotactic radiosurgery (SRS) may be an effective treatment option. METHODS: We retrospectively reviewed 34 patients (41 lesions) treated with salvage SRS for recurrent GBM between 2004 and 2012. Initial surgical treatments were gross total resection (58%), subtotal resection (STR) (24%), and biopsy (18%). All patients were treated with prior radiation therapy...

PURPOSE: Our preferred treatment for juxtapapillary choroidal melanoma is stereotactic radiotherapy. We aim to describe our immobilization system and quantify its reproducibility. MATERIALS AND METHODS: Patients were identified in our radiosurgery database. Patients were imaged at computed tomography simulator with an in-house system which allows visual monitoring of the eye as the patient fixates a small target. All patients were reimaged at least once prior to and/or during radiotherapy...

OBJECTIVE: Gamma Knife(®) (GK) (Elekta Instruments, Stockholm, Sweden) radiosurgery is well established for treatment of brain metastases. There are limited data on patients treated with GK from gynecological cancers. The authors sought to determine the effectiveness of the GK in patients with brain metastases from gynecological cancers. METHODS: An IRB-approved database was queried for patients with gynecologic cancers treated with GK between June 1996 and May 2016...
