Seemingly complete removal of histologically benign intracranial meningioma: late recurrence rate and factors predicting recurrence in 657 patients. A multivariate analysis.
TL;DR: Multivariate analysis showed that coagulation of the dural insertion, invasion of bone, and soft consistency of tumor were strong risk factors for recurrence in meningioma patients with high recurrence rates.

Atypical and anaplastic meningiomas: radiology, surgery, radiotherapy, and outcome.
TL;DR: Out of 936 primary intracranial meningiomas, 94.3% were histologically benign (grade I), 4.7% atypical (grade II), and 1.0% anaplastic (grade III); one recurrence was sarcomatous (grade IV).

TL;DR: Postoperative radiotherapy and/or chemotherapy were significantly associated with increased patient survival time and the tumor was found throughout the entire CNS, usually superficially and closely related to the meninges.

Factors Affecting Operative and Excess Long-term Mortality in 935 Patients with Intracranial Meningioma
TL;DR: Between 1953 and 1980, a total of 935 patients underwent surgery for intracranial meningioma in the Department of Neurosurgery of the Helsinki University Hospital, and the patients were followed up until death or the end of the year 1987.

TL;DR: Multivariate analysis indicates extent of resection, adjuvant radiotherapy, and recurrence status are independent prognostic factors, and malignant meningiomas display a tendency for post surgical recurrence, with recurrence significantly increased for multicentric and recurrent disease.

TL;DR: Among the recurrences, there was a significantly higher degree of cellularity and increased mitotic rate and, probably, of cortical invasion, while nuclear pleomorphism, increased vascularity, and focal necroses showed no definite differences.
