Meningiomas are, in most cases, low-grade intracranial tumours (1):

  • a systematic review found that
    • vast majority of meningiomas express progesterone receptors in almost three-quarters of cases
    • the proportion of cases in which progesterone receptors are present is greater in some situations:
      • 1. female gender;
      • 2. the period of genital activity in women;
      • 3. during pregnancy or postpartum;
      • 4. under hormonal treatment
    • presence of progesterone receptors is associated with significantly more favorable prognostic factors
      • grade 1 meningiomas express progesterone receptors in more than three-quarters of cases
      • grade 3 meningiomas express progesterone receptors in less than 20%
      • recurrent meningiomas express significantly less progesterone receptors

A French study of 18,061 cases matched to 90,305 controls found prolonged use (≥one year) of medrogestone, medroxyprogesterone acetate, and promegestone increased the risk of intracranial meningioma. No excess risk found for progesterone, dydrogesterone, or levonorgestrel IUS:

  • for injectable medroxyprogesterone acetate, the excess risk of meningioma was 9 exposed cases /18,061cases (0.05%) versus 11 exposed controls/90,305 controls (0.01%), odds ratio 5.55 (95% CI 2.27 to 13.56)
  • prolonged use of medrogestone (5 mg, oral), medroxyprogesterone acetate (150 mg, injectable), and promegestone (0.125/0.5 mg, oral) was found to be associated with an excess risk of intracranial meningioma

A dose-dependent relationship between the incidence and growth of meningiomas and hormonal treatment with the progestin cyproterone acetate (CPA) has been established (3):

  • CPA-associated meningiomas seem to be mainly located in the anterior and middle skull base, are more likely to be multiple, may harbour P1K3CA mutations in up to one-third of cases, and are more common with a longer duration of treatment
