Abstract
- Meningiomas had long been considered radioresistant and therefore the role of radiation therapy in its treatment remains controversial. Lately, however, most of the retrospective analysis of meningiomas indicates that radiation therapy does show some degree of beneficial effects not only for malignant but also for benign meningiomas with the advanced technology and increased amount of radiation therapy, the rate of growth of tumor had been successfully slowed and local recurrence rate is also reduced following subtotal resection. We have performed conventional high dose radiation therapy on 7 cases of meningiomas(four cases of meningotheliomatous meningiomas, and three cases of malignant meningiomas). Of the 7 cases, the residual mass of 6 had decreased in size and neurological improvement was also evident. However, the 7th case resulted in complicated hydrocephalus. These cases are presented and the effect of conventional radiation therapy is discussed together with the review of literatures.
