Atypical and anaplastic meningiomas: prognostic implications of clinicopathological features.
OBJECTIVES To evaluate patient outcome and investigate the prognostic factors of high-grade meningiomas by adopting the 2000 World Health Organization (WHO) classification system. METHODS Between 1986 and 2004, 74 patients were diagnosed with high-grade meningioma: 33 with atypical and 41 with anaplastic meningioma. The mean follow-up was 58.5 months. We reclassified all surgical specimens, a...
متن کاملAn analysis of prognostic factors associated with recurrence in the treatment of atypical meningiomas
BACKGROUND There has been increased reporting of atypical meningioma (grade II) since the World Health Organization reclassification in 2000, and the use of postoperative radiation therapy (RT) in the treatment of these tumors is controversial. We evaluated patients treated at our institution to identify patient subgroups with increased risk of recurrence that may benefit from adjuvant RT. ME...
متن کاملClinicopathological prognostic factors and patterns of recurrence in vulvar cancer.

The aim of this study was to determine prognostic variables for recurrence and survival and to identify patterns of recurrence in patients with vulvar cancer. PATIENTS AND METHODS All patients (n = 103) with primary vulvar cancer treated at the University Medical Center Hambur...
متن کاملThe potential risk factors for atypical and anaplastic meningiomas: clinical series of 1,239 cases.
BACKGROUND Determining factors that could accurately predict pathological features of meningiomas before histological diagnosis would help surgeons to proper balance the risk of operation and the resection grade. The aim of this study was to explore the potential risk factors for atypical (WHO Grade II) and anaplastic (WHO Grade III) meningiomas. METHODS Records of 1,239 patients between Janu...
متن کاملLong Term Surgical Outcome and Prognostic Factors of Atypical and Malignant Meningiomas
Atypical and malignant meningiomas are rare. Our aim was to examine the treatment outcomes following surgical resection, and analyze associations between clinical characteristics and overall survival (OS) or relapse free survival (RFS). 102 patients with atypical or malignant meningiomas underwent microsurgical resection between June 2001 and November 2009 were analyzed retrospectively. We comp...
