Radiation Therapy in the Management of Meningiomas
Although most meningiomas are benign, they have a surprisingly wide spectrum of clinical and histological characteristics. The WHO classification attempts to better predict the spectrum of clinical characteristics with a histological grading system based on statistically significant clinical-pathological correlations (1). There are three types of meningiomas in this classification; benign (WHO ...
متن کاملRole of radiation therapy in treating intracranial meningiomas.
Surgery is the mainstay for many patients with meningiomas, and it remains the standard. In large single-institution series, gross-total resection has been reported to achieve 5-, 10-, and 15-year recurrence-free survival rates of approximately 90, 80, and 70%, respectively. There are a growing number of series of patients with prolonged follow-up in which authors have evaluated fractionated ex...
متن کاملIntraoperative radiation therapy as an adjunctive therapy for huge and highly vascular parasagittal meningiomas.
This case presents a 34-year-old man who had a huge parasagittal meningioma. Initial treatment consisted of preoperative external carotid artery embolization and partial tumor resection. During the resection, we found that the tumor invaded the adjacent calvarium, and due to massive hemorrhage, total removal of the tumor was impossible. The patient was treated with intraoperative radiation ther...
متن کاملStereotactic radiation treatment for recurrent nonbenign meningiomas.
OBJECT The authors analyzed the results of stereotactic radiosurgery (SRS) and stereotactic radiotherapy (SRT) for the treatment of recurrent meningiomas that were described at initial resection as showing aggressive, atypical, or malignant features (nonbenign). METHODS Twenty-five patients who underwent SRS and/or SRT for nonbenign meningiomas between December 1992 and August 2004 were inclu...
متن کاملSurgical and Radiation Treatment of Skull Base Meningiomas
Meningiomas comprise approximately 20% of adult primary intracranial neoplasms. Of these, benign meningiomas are known to have an indolent growth pattern, usually without infiltration into adjacent nervous tissue. Because meningiomas have a well-circumscribed character, surgery has historically been the preferred treatment when total resection can be achieved with reasonable morbidity. Surgical...
