Radiation Therapy with a Simultaneous Integrated Boost
Radiotherapy has an established role in the treatment of cancer and represents a definitive, less invasive approach for various cancer types. Its main aim is to deliver the maximum dose to the tumor with minimal toxicity on neighboring healthy tissues. Therefore, the precise determination of the target and its spatial relation to critical surrounding organs is of main importance. New imaging mo...
متن کاملEstimating prognosis at the time of repeat whole brain radiation therapy for multiple brain metastases: The reirradiation score
Purpose Whole brain radiation therapy (WBRT) remains the standard of care for patients with multiple brain metastases, but more than half of treated patients will develop intracranial progression. Because there is no clear consensus on the optimal therapeutic approach, a prognostic index would be helpful to guide treatment options at progression. We explored whether the recursive partitioning a...
متن کاملSimultaneous infield boost with helical tomotherapy for patients with 1 to 3 brain metastases.
OBJECTIVE We sought to model the feasibility of a simultaneous in field boost (SIB) to individual brain metastases during a course of whole brain radiotherapy (WBXRT) using helical tomotherapy (HT) intensity-modulated radiation therapy. PATIENTS AND METHODS Planning computed tomography data from 14 patients with 1 to 3 brain metastases were used to model an intralesional SIB delivery that yie...
متن کاملFeasibility of simultaneous integrated boost with forward intensity-modulated radiation therapy for multiple brain metastases
AIM OF THE STUDY To evaluate the feasibility of whole-brain radiotherapy (WBRT) with a simultaneous integrated boost (SIB) by forward intensity-modulated radiation therapy (IMRT) in patients with 1-3 brain metastases. MATERIAL AND METHODS Two forward IMRT plans were implemented among 18 patients. In plan A, the prescribed dose was 30 Gy to the whole brain (PTVWBRT) and 50 Gy to individual bra...
متن کاملOutcomes after whole brain reirradiation in patients with brain metastases.
PURPOSE Patients with brain metastases are often treated with whole brain radiation therapy (WBRT) for purposes of palliation. The treatment of those who experience subsequent intracranial disease progression can include a second course of WBRT, although there is controversy surrounding its safety and efficacy. This study examines the outcomes in patients at Massachusetts General Hospital who u...
