Radiotherapy for atypical meningiomas.
OBJECT The role of postoperative radiotherapy in patients undergoing first-time resection of WHO Grade II meningioma remains unclear as reflected by varied practices in published clinical studies and national professional surveys. Much of the relevant literature is based on pre-2000 WHO grading criteria for atypical meningiomas. Authors in this study set out to explore the role of postoperative...
متن کاملAtypical and Malignant Meningiomas: Increasing Incidence?
Introduction: Traditionally, the vast majority of meningiomas have been benign lesions with a low propensity for regrowth or spread following gross total removal. Over the past five years, our center has encountered a sharp increase in the percentage of meningiomas with pathological evidence of atypical or malignant features. This report addresses our growing experience with this entity. Method...
متن کاملAtypical and anaplastic meningiomas: prognostic implications of clinicopathological features.

متن کاملAdjuvant radiotherapy for atypical and malignant meningiomas: a systematic review.
Atypical meningiomas (AMs) and malignant meningiomas (MMs) are tumors with a lower incidence and poorer prognosis than benign meningiomas. The role of radiotherapy as an adjuvant to surgical resection, especially for AMs, is incompletely defined. In this study, the English-language literature was systematically reviewed for studies that reported tumor characteristics, treatment parameters, and ...
متن کاملp53 and PCNA expression in benign, atypical and malignant meningiomas.
OBJECTIVE Alterations: p53 genes are turning out to be the most common genetic alterations in human cancers. Due to long half-life of mutated p53, its detection is possible by immunohistochemistry. Proliferating cell nuclear antigen (PCNA) is expressed by dividing cells, hence has been shown to correlate with prognosis. We have used monoclonal antibodies protein DO-7 (p53) and PC10 (PCNA) to se...
