Abstract: A brand new examine highlights a major hyperlink between extended use of sure progestogen hormone medication and an elevated threat of creating intracranial meningioma, a sort of mind tumor. Researchers analyzed knowledge from 18,061 ladies who underwent surgical procedure for intracranial meningioma, evaluating their progestogen use to 90,305 controls.The examine discovered that extended use of particular progestogens, together with medrogestone, medroxyprogesterone acetate, and promegestone, is related to an elevated threat of requiring surgical procedure for meningioma. This analysis underscores the pressing want for additional research to know this threat absolutely, particularly given the widespread use of those hormones in treating circumstances like endometriosis and as a part of contraceptive strategies.Key Information:Hyperlink to Mind Tumours Recognized: Extended use of sure progestogens is related to a 2.7 to five.6-fold elevated threat of intracranial meningioma requiring surgical procedure.Large Use of Progestogens: Medroxyprogesterone acetate, one of many progestogens linked to elevated meningioma threat, is used for contraception by an estimated 74 million ladies worldwide.Want for Additional Analysis: The examine requires pressing additional investigation to higher perceive the dangers related to progestogen use, contemplating the potential public well being implications.Supply: BMJProlonged use of sure progestogen hormone medication is related to an elevated threat of creating a sort of mind tumour generally known as an intracranial meningioma, finds a examine from France revealed by The BMJ immediately.The researchers say this examine is the primary to evaluate the danger related to progestogens utilized by hundreds of thousands of girls worldwide, and additional research are urgently wanted to realize a greater understanding of this threat.Progestogens are just like the pure hormone progesterone, that are broadly used for gynaecological circumstances resembling endometriosis and polycystic ovary syndrome, and in menopausal hormone remedy and contraceptives. However there are numerous different progestogens for which the danger of meningioma related to their use has not been estimated individually. Credit score: Neuroscience NewsMeningiomas are largely non-cancerous tumours within the layers of tissue (meninges) that cowl the mind and spinal twine. Elements resembling older age, feminine intercourse, and publicity to 3 high-dose progestogens (nomegestrol, chlormadinone, and cyproterone acetate) are already identified to extend the danger of meningioma.However there are numerous different progestogens for which the danger of meningioma related to their use has not been estimated individually.To handle this data hole, researchers got down to consider the true life threat of intracranial meningioma requiring surgical procedure in ladies related to use of a number of progestogens with completely different routes of administration.They used knowledge from the French nationwide well being knowledge system (SNDS) for 18,061 ladies (common age 58) who underwent intracranial meningioma surgical procedure from 2009-18.Every case was matched to 5 management ladies with out intracranial meningioma (complete 90,305) by yr of beginning and space of residence.The progestogens examined have been progesterone, hydroxyprogesterone, dydrogesterone, medrogestone, medroxyprogesterone acetate, promegestone, dienogest, and levonorgestrel intrauterine techniques.For every progestogen, use was outlined as at the very least one prescription within the yr earlier than hospital admission or inside 3-5 years for levonorgestrel intrauterine techniques.Use of at the very least one of many three high-dose progestogens identified to extend the danger of meningioma within the 3 years earlier than hospital admission was additionally recorded to minimise bias.After taking account of different doubtlessly influential elements, extended use (a yr or extra) of medrogestone was related to a 4.1-fold elevated threat of intracranial meningioma requiring surgical procedure.Extended use of medroxyprogesterone acetate injection was related to a 5.6-fold elevated threat, and extended use of promegestone was linked to a 2.7-fold elevated threat.There gave the impression to be no such threat for lower than one yr of use of those progestogens. As anticipated, there was additionally an extra threat of meningioma for girls uncovered to chlormadinone acetate, nomegestrol acetate, and cyproterone acetate, all of that are identified to extend the danger of meningioma.Nonetheless, outcomes confirmed no extra threat of meningioma for progesterone, dydrogesterone, or the broadly used hormonal intrauterine techniques, whatever the dose of levonorgestrel they contained.No conclusions could possibly be drawn about dienogest or hydroxyprogesterone because the variety of uncovered people was too small. That is an observational examine so can’t set up trigger and impact, and the authors acknowledge that the SNDS database lacked info on all of the medical particulars and medical indications for which progestogens are prescribed. Nor have been they in a position to account for genetic predisposition and publicity to excessive dose radiation.Nonetheless, they are saying, on condition that medroxyprogesterone acetate is estimated for use for contraception by 74 million ladies worldwide, the variety of attributable meningiomas could also be doubtlessly excessive.Additional research utilizing different sources of information are urgently wanted to realize a greater understanding of this threat, they conclude.About this mind most cancers analysis newsAuthor: BMJ Media RelationsSource: BMJContact: BMJ Media Relations – BMJImage: The picture is credited to Neuroscience NewsOriginal Analysis: The findings will seem in The BMJ
