OBJECTIVE Numerous studies have confirmed a strong association between progestins and meningiomas and the regression and/or stabilization of meningiomas after discontinuation of treatment. Osteomeningiomas represent a small subgroup of meningiomas that appear to be more common among progestin-related meningiomas. However, the specificity of the behavior of this subset of meningiomas after discontinuation of progestin has not yet been assessed. METHODS Thirty-six patients (mean age 49.5 years) who presented with at least one progestin-related osteomeningioma (48 tumors total) were identified from a prospectively collected database of patients and had been referred to our department for meningioma and had documented use of cyproterone acetate, nomegestrol acetate, and/or chlormadinone acetate. Hormonal treatment was stopped at the time of diagnosis for all the patients, and the clinical and radiological evolution of this subgroup of tumors was evaluated. RESULTS For half of the 36 patients, treatment was prescribed for signs of hyperandrogenism, such as hirsutism, alopecia, or acne. Most lesions were spheno-orbital (35.4%) or frontal (31.2%). Although the tissular part of the meningioma shrank in 77.1% of cases, the osseous part exhibited discordant behavior with 81.3% showing volume progression. The combination of estrogens, as well as the prolonged duration of progestin treatment, seems to increase the risk of progression of the osseous part after treatment discontinuation (p = 0.02 and p = 0.028, respectively). No patient required surgical treatment at diagnosis or during the study. CONCLUSIONS These results show that while the soft intracranial part of progestin-related osteomeningioma tumor is the most likely to regress after treatment discontinuation, the bony part is more likely to increase in volume. These findings suggest the need for careful follow-up of these patients, especially those with tumors near the optical apparatus.

The implementation of the new European Clinical Trial Regulation on 31 January 2022, is a major step to promote clinical research in Europe. The French National Agency for Medicines and Health Products Safety (ANSM) proposes to share some key aspects of the preparation for the application of the Regulation initiated in 2017 and to discuss shared indicators that should be considered to monitor clinical trials opportunities on a territory with regards to access to innovation for patients and attractiveness for sponsors. New criteria based on the time from the first request for authorisation to the first inclusion could be of particular interest to appraise the implementation of the European Clinical Trial Regulation.

Background The behavior of meningiomas under influence of progestin therapy remains unclear. Objective To investigate the relationship between growth kinetics of intracranial meningiomas and usage of the progestin cyproterone acetate (PCA). Methods This study prospectively followed 108 women with 262 intracranial meningiomas and documented PCA use. A per-meningioma analysis was conducted. Changes in meningioma volumes over time, and meningioma growth velocities, were measured on magnetic resonance imaging (MRI) after stopping PCA treatment. Results Mean follow-up time was 30 (standard deviation [SD] 29) mo. Ten (4%) meningiomas were treated surgically at presentation. The other 252 meningiomas were followed after stopping PCA treatment. Overall, followed meningiomas decreased their volumes by 33% on average (SD 28%). A total of 188 (72%) meningiomas decreased, 51 (20%) meningiomas remained stable, and 13 (4%) increased in volume of which 3 (1%) were surgically treated because of radiological progression during follow-up after PCA withdrawal. In total, 239 of 262 (91%) meningiomas regressed or stabilized during follow-up. Subgroup analysis in 7 women with 19 meningiomas with follow-up before and after PCA withdrawal demonstrated that meningioma growth velocity changed statistically significantly (P = .02). Meningiomas grew (average velocity of 0.25 mm3/day) while patients were using PCA and shrank (average velocity of -0.54 mm3/day) after discontinuation of PCA. Conclusion Ninety-one percent of intracranial meningiomas in female patients with long-term PCA use decrease or stabilize on MRI after stopping PCA treatment. Meningioma growth kinetics change significantly from growth during PCA usage to shrinkage after PCA withdrawal.

Decisions on market authorization (MA) and reimbursement have different durations across countries because of health technology assessment (HTA) procedures and negotiations between manufacturers and national authorities. To overcome this delay, France has implemented a Temporary Authorization for Use (ATU) program that allows early access to drugs before MA, in order to treat patients with unmet medical needs. The objectives of our study were to establish the added therapeutic benefit (ATB) of ATUs for solid tumors and to investigate the correlations between three tools evaluating ATB and survival outcomes and drug costs. Data on ATUs granted from January 2009 to December 2019 to treat solid tumors were analyzed. An assessment of their ATB was conducted using the American Society of Clinical Oncology-Value Framework (ASCO-VF), the European Society for Medical Oncology-Magnitude Clinical Benefit Scale (ESMO-MCBS) and the French HTA criterion, clinical added value (CAV). The latter score determines reimbursement and national market access. Thirty-five drugs in 39 indications were granted ATUs. All of them obtained MA and derived a clinical benefit to be reimbursed by the Social Security. Twenty-eight (71.8%) had CAV compared to preexisting therapies. 24/38 (63.2%) had a 4-5 ESMO-MCBS score and 19/33 (57.6%) had an ASCO-VF score over 45. No correlations were found between cost, PFS, OS, CAV and ASCO-VF score, while high ESMO-MCBS scores were correlated to OS. In conclusion, many patients were treated with innovations before MA thanks to ATU, although there are discrepancies between ATB scales, hence the importance of international collaboration in the evaluation of innovative therapies.

Objective To assess the risk of meningioma associated with use of high dose cyproterone acetate, a progestogen indicated for clinical hyperandrogenism. Design Observational cohort study. Setting Data from SNDS, the French administrative healthcare database, between 2007 and 2015. Participants 253 777 girls and women aged 7-70 years living in France who started cyproterone acetate between 2007 and 2014. Participants had at least one reimbursement for high dose cyproterone acetate and no history of meningioma or benign brain tumour, or long term disease status. Participants were considered to be exposed when they had received a cumulative dose of at least 3 g during the first six months (139 222 participants) and very slightly exposed (control group) when they had received a cumulative dose of less than 3 g (114 555 participants). 10 876 transgender participants (male to female) were included in an additional analysis. Main outcome measure Surgery (resection or decompression) or radiotherapy for one or more intracranial meningiomas. Results Overall, 69 meningiomas in the exposed group (during 289 544 person years of follow-up) and 20 meningiomas in the control group (during 439 949 person years of follow-up) were treated by surgery or radiotherapy. The incidence of meningioma in the two groups was 23.8 and 4.5 per 100 000 person years, respectively (crude relative risk 5.2, 95% confidence interval 3.2 to 8.6; adjusted hazard ratio 6.6, 95% confidence interval 4.0 to 11.1). The adjusted hazard ratio for a cumulative dose of cyproterone acetate of more than 60 g was 21.7 (10.8 to 43.5). After discontinuation of cyproterone acetate for one year, the risk of meningioma in the exposed group was 1.8-fold higher (1.0 to 3.2) than in the control group. In a complementary analysis, 463 women with meningioma were observed among 123 997 already using cyproterone acetate in 2006 (risk of 383 per 100 000 person years in the group with the highest exposure in terms of cumulative dose). Meningiomas located in the anterior skull base and middle skull base, particularly the medial third of the middle skull base, involving the spheno-orbital region, appeared to be specific to cyproterone acetate. An additional analysis of transgender participants showed a high risk of meningioma (three per 14 460 person years; 20.7 per 100 000 person years). Conclusions A strong dose-effect relation was observed between use of cyproterone acetate and risk of intracranial meningiomas. A noticeable reduction in risk was observed after discontinuation of treatment.

Dans le cadre de la pandémie COVID-19, des donneurs ont signalé à l’établissement de transfusion sanguine (ETS) après leur don de sang une infection par le SARS-CoV-2 ou le contact avec une personne infectée. Lorsque les produits issus de ces dons ont été distribués ou délivrés par l’ETS, et que cette information post don (IPD) doit être nécessairement connue de(s) l’établissement(s) destinataire(s), des prescripteurs, une fiche d’information post don (FIPD) doit être déclarée en hémovigilance (e-FIT). En mars 2020, 2 nouveaux items « nature d’IPD » ont été créés dans e-FIT : « Coronavirus » et « Risque coronavirus (exposition) ». Le premier item correspond au cas où le donneur (avec ou sans symptômes) est diagnostiqué positif au SARS-CoV-2. Le second item est sélectionné en cas de symptômes évocateurs chez le donneur mais sans confirmation biologique ou de contact avec une personne infectée. À ce jour, 147 FIPDs « Coronavirus » et 38 FIPDs « Risque Coronavirus » ont été déclarées dans e-FIT. Sachant que pour les plaquettes, l’inactivation des pathogènes par Intercept® (amotosalen) est réputée performante sur les coronavirus (SARS-CoV et MERS-CoV) et que les plasmas ont été orientés vers la plasmathèque, les enquêtes descendantes d’hémovigilance ont principalement concerné les receveurs de CGR. L’analyse des déclarations a apporté des informations sur : symptômes du donneur, délais entre le don et l’apparition de l’IPD, confirmation biologique ou non de l’infection, devenir des produits sanguins, résultat de la paillette du don pour le SARS-CoV-2, résultat des enquêtes menées chez des receveurs de CGR. Celles-ci n’ont pas mis en évidence de transmission transfusionnelle du SARS-CoV-2.
