Recommendations on the management of meningioma and sex hormone therapy: The results of a collaborative effort between neurosurgical, endocrine and gynecological societies.

INTRODUCTION

Exogenous and endogenous sex hormones, especially Progesterone agonists, may be causally linked to meningioma progression. Cessation of treatment leads to stabilization or regression of Progestin-induced meningioma. In many cases, avoiding sex hormone therapy may be possible in the context of meningioma treatment. However, hormonal treatment is not always easily replaceable and concise real-world recommendations regarding sex hormones and meningioma are lacking.

MATERIAL AND METHODS

A combined effort was initiated between Neurosurgical, Gynaecological and Endocrinological societies of Belgium to gather relevant information regarding sex hormone therapies and meningioma. After complete literature review, consensual recommendations were established.

RESULTS

Collegial recommendations regarding sex hormones therapies and meningioma in the context of oral contraceptives, menopause hormonal treatment, fertility treatment, pregnancy and gender-affirming therapies are emitted and nuanced.

DISCUSSION AND CONCLUSION

Withdrawal and monitoring of sex hormone therapies are discussed in detail.A decision tree regarding Meningioma and Combined contraception, Progestin Contraception, Menopause Hormonal treatment, Progestin and Gender-affirming therapy is suggested.
