Survival Benefit of Prognostic Factors and Treatment in Adult Patients with Recurrent Anaplastic Meningioma: A Retrospective Case Series and Systematic Literature Review. World Neurosurg 2022; 166:e758-e769. [PMID: 35944862 DOI: 10.1016/j.wneu.2022.07.099] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Revised: 07/19/2022] [Accepted: 07/20/2022] [Indexed: 12/15/2022]
Abstract
BACKGROUND Recurrence rates of anaplastic meningioma (AM) are high even after a complete resection with postoperative radiotherapy. OBJECTIVE This study aimed to evaluate predictors and treatment affecting survival of recurrent AM based on our series and a systematic literature review (SLR). METHODS Our single-institute (SI) data enrolled patients with first recurrent AM, treated in our hospital from 2012 to 2018. We retrieved eligible cases from SLR from 1966 to 2020. Our SI data and pooled data, integrating SI and SLR data, were subject to Cox proportional hazard regression analysis. RESULTS Analysis from SI data (n = 38) showed that second recurrence-free survival (RFS) was associated with intervals (HR [hazard ratio], 0.263; P = 0.002), preoperative Karnofsky Performance Status (KPS) (HR, 0.450; P = 0.043), radiotherapy (HR, 0.395; P = 0.047), whereas overall survival (OS) was related to preoperative KPS (HR, 0.411; P = 0.037) and tumor size (HR, 3.429; P = 0.007). The pooled data (n = 60) indicated that short intervals (HR, 0.370; P = 0.002) and the use of radiotherapy (HR, 0.318; P = 0.003) improved second RFS and number of resections ≥3 (HR, 0.210; P = 0.002) and radiotherapy (HR, 0.209; P = 0.002) prolonged OS. Furthermore, the overall second RFS (P = 0.024) and OS (P = 0.031) stratified by 4 treatment protocols differed significantly. CONCLUSIONS Early managements of patients with AM, before presence of poor preoperative KPS and large tumor size, are critical for survival. For patients with recurrent AM, survival benefits could be obtained from radiotherapy and multiple resections.

Predicting High-Value Care Outcomes After Surgery for Non-Skull Base Meningiomas. World Neurosurg 2021; 159:e130-e138. [PMID: 34896348 DOI: 10.1016/j.wneu.2021.12.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Accepted: 12/03/2021] [Indexed: 11/16/2022]
Abstract
OBJECTIVE A need exists to better understand the prognostic factors that influence high-value care outcomes after meningioma surgery. The goal of the present study was to develop predictive models to determine the patients at risk of experiencing an extended hospital length of stay (LOS), nonroutine discharge disposition, and/or a 90-day hospital readmission after non-skull base meningioma resection. METHODS In the present study, we analyzed the data from 396 patients who had undergone surgical resection of non-skull base meningiomas at a single institution between January 1, 2005 and December 31, 2020. The Mann-Whitney U test was used for bivariate analysis of the continuous variables and the Fisher exact test for bivariate analysis of the categorical variables. A multivariate analysis was conducted using logistic regression models. RESULTS Most patients had had a falcine or parasagittal meningioma (66.2%), with the remainder having convexity (31.8%) or intraventricular (2.0%) tumors. Nonelective surgery (P < 0.0001) and an increased tumor volume (P = 0.0022) were significantly associated with a LOS >4 days on multivariate analysis. The independent predictors of a nonroutine discharge disposition included male sex (P = 0.0090), nonmarried status (P = 0.024), nonelective surgery (P = 0.0067), tumor location within the parasagittal or intraventricular region (P = 0.0084), and an increased modified frailty index score (P = 0.039). Hospital readmission within 90 days was independently associated with nonprivate insurance (P = 0.010) and nonmarried status (P = 0.0081). Three models predicting for a prolonged LOS, nonroutine discharge disposition, and 90-day readmission were implemented in the form of an open-access, online calculator (available at: https://neurooncsurgery3.shinyapps.io/non_skull_base_meningiomas/). CONCLUSIONS After external validation, our open-access, online calculator could be useful for assessing the likelihood of adverse postoperative outcomes for patients undergoing surgery of non-skull base meningioma.

Malignant intraventricular meningioma: literature review and case report. Neurosurg Rev 2021; 45:151-166. [PMID: 34159472 DOI: 10.1007/s10143-021-01585-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2021] [Revised: 05/19/2021] [Accepted: 06/10/2021] [Indexed: 10/21/2022]
Abstract
Malignant intraventricular meningiomas (IVMs) are very rare with only a few reported cases. A midline search up to December 2020 selected 40 articles for a total of 65 patients. The inclusion criteria were series and case reports in English language, as well as papers written in other languages, but with abstracts written in English. Malignant IVMs at the first diagnosis (group A, 50 patients) and those with anaplastic transformation from previous WHO grades I and II tumors (group B, 15 patients) were separately analyzed. The unique personal case among 1285 meningiomas (0.078%) is also added. Malignant IVMs mainly occur in women (61%) with a median age of 45 years and are mainly located in the lateral ventricle (93%) and trigonal region (74%), with no cases in the fourth ventricle. Irregular borders (80%), heterogeneous enhancement (83%), and perilesional edema (76%) are the most frequent radiological findings. The histology was mainly pure anaplastic (85%), whereas papillary (7%), rhabdoid (5%), and mixed forms (3%) are very rare. The CSF spread was found in 60% of the cases. The prognosis is very dismal, with an overall median survival of 17.5 months after surgery for the anaplastic forms. Malignant IVMs at initial diagnosis (group A) show better overall survival (25 months) than those occurring from anaplastic transformation of lower grade tumors (group B) (10.1 months).
