RESUMO
OBJECTIVE: Papillary meningioma is rare and displays an aggressive clinical behavior with poor prognosis. Therefore, we performed an extensive literature review to evaluate the adverse factors and treatment strategy of survival. METHOD: We performed Ovid, Medline, Embase, Pubmed, Web of Science and Cochrane database queries for articles published between 1938 and 2019 with the search term "WHO grade III meningioma" or "papillary meningioma" and "central nervous system", "cerebral", or "intracranial". RESULTS: After a careful evaluation, a total of 19 studies were included. The entire cohort included the 67 patients, 34 (50.7%) were male and 33 (49.3%) were female with a mean age of 32.6 ± 2.1 years ranging from 4.5 months to 74 years. Gross total resection was achieved in 48 (71.6%) cases, and 29 (51.8%) patients received postoperative radiation. The mean follow-up period was 42.3 ± 4.4 months (range, 2-197 months). Thirty-six (53.7%) patients happened to recurrences, 11 (16.4%) patients happened to extracranial metastasis and 25 (37.3%) patients died. Univariate analysis revealed that the MIB > 5% trended toward a shorter time to recurrence (p = 0.084). Gross total resection was associated with favorable progression-free survival (p = 0.007) and overall survival (p = 0.001). Postoperative radiation was associated with favorable progression-free survival (p = 0.001). CONCLUSIONS: Gross total resection and adjuvant radiation were recommended as the initial treatment option for patients with papillary meningioma.
