The optimal management of patients with few brain metastases is complex. On one hand, stereotactic radiation therapy is a keystone of treatment but is only applicable to highly selected patients fulfilling specific criteria who have access to an adequate radiation unit. On the other, whole-brain radiation therapy may improve survival, but deleterious effects on neurocognitive functions are well...

BACKGROUND Structural follow-up magnetic resonance imaging (MRI) after stereotactic radiosurgery (SRS) for brain metastases frequently displays local changes in the area of applied irradiation, which are often difficult to interpret (e.g., local tumor recurrence, radiation-induced changes). The use of stereotactic biopsy for histological assessment of these changes has a high diagnostic accurac...

High local control and low toxicity rates are seen in patients treated with stereotactic body radiotherapy (SBRT) for peripheral lung tumours [1,2]. According to the Advisory Committee on Radiation...

Accelerated partial breast irradiation has caused higher than expected rates of poor cosmesis. At our institution, a novel breast stereotactic radiotherapy device has demonstrated dosimetric distributions similar to those in brachytherapy. This study analyzed comparative dose distributions achieved with the device and intensity-modulated radiation therapy accelerated partial breast irradiation....

Radiotherapy is a treatment of carcinogenic tumors using ionising radiation and the improvement radiotherapy techniques has been conducted to protection healthy tissues. Recent implementations have employed static fields with small dimensions. The interests for this work were fields, used in modern such as Stereotactic Radiation Therapy (SRS) Intensity Modulated (IMRT).

PURPOSE To analyze the utilization and fractionation of extreme hypofractionation via stereotactic body radiotherapy (SBRT) in the treatment of prostate cancer. MATERIALS AND METHODS Data was analyzed on men diagnosed with localized prostate cancer between 2004-2012 and treated with definitive-intent radiation therapy, as captured in the National Cancer Database. This database is a hospital-b...

 If a product excludes coverage for a service, it is not covered, and medical policy criteria do not apply.  If a commercial product, including an Essential Plan product, covers a specific service, medical policy criteria apply to the benefit.  If a Medicare product covers a specific service, and there is no national or local Medicare coverage decision for the service, medical policy criteri...

We report staged embolization and stereotactic radiation in a true adult choroidal vein of Galen malformation. Management dilemmas and their resolutions are also discussed.

References .......................................................................... 59 Abstract In recent years, increasing number of cancer patients are treated with stereotactic radiosurgery (SRS) or stereotactic body radiation therapy (SBRT), which deliver hypofractionated irradiation with high-dose per fraction . It is highly likely that the radiobiological principles such as 4 Rs (Reoxyg...

OBJECTIVE To design a treatment algorithm based on experience with facial nerve schwannomas (FNS) over a 30-year period. STUDY DESIGN Retrospective chart review. METHOD Seventy-nine patients with facial nerve schwannomas seen from 1979 through 2009 at a tertiary referral private otologic practice were categorized by treatment modality. Interventions included surgical resection with grafting...
