“…Although most meningiomas are benign, approximately 20% of patients have aggressive meningiomas with poor a prognosis ( 1 ). Many studies have confirmed that the incidence of meningioma is disparate by sex, and the female-to-male ratio of IR is over than three in the 35–54-year group ( 1 , 2 , 13 , 14 ). However, the underlying mechanism remains unclear.…”

“…Herein, we observed that the IR of meningioma increased with age, and the IR of 50-54 years was 2.92 and 2.77 times of IR in 35-39 years for females and males, respectively. Many research also reported that the age maybe a risk factor of meningioma, since the incidence of meningioma increased with age, especially for the patients over 60 years old ( 1 , 14 , 28 – 30 ). Mechanistically, evidence of aging-related genome-wide DNA methylation alterations in meningiomas may explained this phenomenon ( 31 – 33 ).…”

BackgroundThe incidence of meningioma is disparate to sex: meningiomas are more common in women than in men, especially in middle-aged women. Understanding the epidemiology and survival of middle-aged women with meningiomas would help estimate their public health impacts and optimize risk stratification.MethodsData on middle-aged (35–54 years) female patients with meningiomas between 2004 and 2018 were obtained from the SEER database. Age-adjusted incidence rates per 100 000 population-years were calculated. Kaplan-Meier and multivariate Cox proportional hazard models were utilized in the overall survival (OS) analysis.ResultsData from 18302 female patients with meningioma were analyzed. The distribution of patients increased with age. Most patients were White and non-Hispanic, according to race and ethnicity, respectively. Over the past 15 years, non-malignant meningiomas have shown an increasing trend; however, malignant meningiomas have shown an opposite trend. Older age, Black population, and large non-malignant meningiomas tend to have worse prognoses. Surgical resection improves OS, and the extent of resection is a critical prognostic factor.ConclusionsThis study observed an increase in non-malignant meningiomas and a decrease in the incidence of malignant meningiomas in middle-aged females. The prognosis deteriorated with age, in Black people, and with large tumor size. Additionally, the extent of tumor excision was found to be a significant prognostic factor.
