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...

PURPOSE: Radiosurgery (RS) is a well-established treatment in selected patients with brain metastasis. The aim of this study is to compare the differences between CyberKnife (CK) and TomoTherapy (HT) treatment plans of RS of single brain metastasis (BM) to define when HT should be used in cases beyond Cyberknife-when both systems are readily available for the radiation oncologist. METHODS AND MATERIALS: Nineteen patients with single brain metastasis treated with CK were re-planned for radiosurgery using TomoTherapy Hi-ART system...

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...

Pasireotide is a recently approved medical treatment for persistent or recurrent Cushing's disease (CD). However, an escape from the initial successful response has not yet been described. A 42-year-old female presented with several symptoms indicative of hypercortisolism. Biochemical evaluation and imaging were consistent with CD due to a pituitary adenoma. Surgical excision of the adenoma was unsuccessful and gamma-knife radiosurgery was followed. Our patient remained hypercortisolemic thus treatment with pasireotide (900 mg subcutaneously twice daily) was decided...

OBJECTIVE Gamma Knife surgery (GKS) is a promising treatment modality for patients with vestibular schwannomas (VSs), but a small percentage of patients have persistent postradiosurgical tumor growth. The aim of this study was to determine the clinical and quantitative MRI features of VS as predictors of long-term tumor control after GKS. METHODS The authors performed a retrospective study of all patients with VS treated with GKS using the Leksell Gamma Knife Unit between 2005 and 2013 at their institution...

OBJECTIVE Advanced microsurgical techniques contribute to reduced morbidity and improved surgical management of meningiomas arising within the cerebellopontine angle (CPA). However, the goal of surgery has evolved to preserve the quality of the patient's life, even if it means leaving residual tumor. Concurrently, Gamma Knife radiosurgery (GKRS) has become an acceptable and effective treatment modality for newly diagnosed, recurrent, or progressive meningiomas of the CPA. The authors review their institutional experience with CPA meningiomas treated with GKRS, surgery, or a combination of surgery and GKRS...

INTRODUCTION: A patient with a small (<3cm) intracranial meningioma can be either observed or treated. Treatment can be either radiosurgery or microsurgery if and when progression of the tumor occurs. We have compared the local tumor growth control and recurrence-free survival (RFS) of microsurgical resection and radiosurgery in small intracranial meningiomas, and we have identified the predictors of unfavorable outcome. MATERIALS AND METHODS: Retrospective review (2005-2016) of 90 consecutive patients with intracranial meningiomas who underwent either microsurgery (n=31) or gamma knife radiosurgery (GKRS, n=59) was done...

Objectives This study aims to report tumor control rates and cranial nerve function after low dose (11.0 Gy) Gamma knife radiosurgery (GKRS) in patients with vestibular schwannomas. Methods A retrospective chart review was performed on 30 consecutive patients with vestibular schwannomas treated from March 2004 to August 2010 with GKRS at the Robert H. Lurie Comprehensive Cancer Center of Northwestern University. The marginal dose for all patients was 11.0 Gy prescribed to the 50% isodose line. Median follow-up time was 42 months...

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...
