Aggressive pituitary tumours, characterized by tumor recurrence and continued progression despite repeated treatments and pituitary carcinomas respond poorly to conventional therapies. The first reports describing the successful use of temozolomide (TMZ), an orally administered alkylating agent used to treat malignant gliomas, in the management of pituitary carcinomas were published in 2006. Following these single case reports small series of patients have detailed the success...

Pituitary endocrine tumours are currently classified by histological, immunocytochemical and numerous ultrastructural characteristics but without prognostic clinical correlations. We investigated the prognostic value of a new clinicopathological classification with grades based on invasion and proliferation, the components of tumour behaviour.This retrospective multicentric case–control study comprised 410 patients who had surgery for a pituitary tu...

Paltusotine is a once-daily, oral, selectively-targeted SST2 agonist in development for the treatment of acromegaly. PATHFNDR-1 (NCT04837040) enrolled patients with acromegaly who had an IGF-1 ≤1xULN on a stable (>12 weeks) dose of lanreotide or octreotide. Patients were randomized 1:1 to receive paltusotine 40 mg/day or placebo for 36 weeks. During the first 24 weeks, the paltusotine dose was titrated (range 20-60 mg) based on IGF-1 and tolerance. Dose changes were ...

We are all aware of the current anxieties over the future of Academic Medicine and Modernising Medical Careers. 10 years ago the BMA cohort of 1995 Medical graduates: Medical Academic Career Intentions was performed. 545 doctors graduating in 1995 were followed up for 10 years. The key findings included: those doctors working in research were doing so to improve future career prospects or as a means to secure a National Training Number (NTN). However being in the transition pe...

MD are the most frequent complaint of women with Cushing Syndrome at the time of diagnosis.Objective: To study the frequency of occurrence of MD in patients with Syndrome Cushing and to characterize their clinical and hormonal parallels. We investigated 34 women (average age of 27 years, variation in age from 18 to 30 years) with a newly identified ACTHA. The patients were divided into 4 groups: (1) the normal cycle is 26–31 days; (2) oligomenorrhea...

TSH secreting pituitary adenomas are rare tumours for which the treatment of choice is neurosurgery but in some cases medical treatment with somatostatin analogs (SSA) can lead to a good control of symptoms and shrinkage of the tumour.The objective of this study was to review 30 patients diagnosed with TSH-omas between October 1981–July 2014, followed-up for a median of 43.93 months (1.12–192.11) in our University Hospital from Lyon, France.</p...

Introduction: 15% of pituitary tumors are considered as aggressive based on resistance to conventional treatment. Less than 40% of these cases respond to temozolomide treatment underlining the need for new therapeutic options. The PI3K/Akt/mTOR pathway, upregulated in different pituitary tumors subtypes, can be targeted by different drugs in particular BKM 120, a pure PI3K inhibitor, and BEZ235, a dual PI3K/mTOR inhibitor.Objective: To study the anti-tum...

The thyrotroph tumors or pituitary neuroendocrine tumors (PitNET) classify as tumors of Pit-1 family. These tumors are rare and may be monohormonal, secreting only TSH, or plurihormonal, secreting TSH-GH±PRL, with or without acromegaly. The objectives of this retrospective study were to confirm the frequency of the plurihormonal subtype and to compare the clinical, biological and pathological characteristics of these two pathological subtypes. We retrospectively studied t...

Objective: To describe the Carney Complex (CNC) manifestations presented by patients harboring the PRKAR1A mutation c.709(-7-2)del (one of the three hotspots) in a large cohort of patients.Methods: Multicenter retrospective study. Age at the diagnosis or at the screening of the different CNC manifestations is described by mean ± standard deviation.Results: Forty patients [12 index cases, 27 females, 46±15 years o...

Background: In a phase 3b, open-label study (NCT02354508) assessing efficacy and safety of long-acting pasireotide in patients with uncontrolled acromegaly after ≥3 months of treatment with first-generation SSAs, 18/123 (15%) patients achieved the primary endpoint of mean growth hormone (mGH) <1.0 μg/l and insulin-like growth factor-1 (IGF-1) <ULN (upper limit of normal) at week 36. Here, we present the results from the extension phase of this study.<p c...
