The choice of therapeutic method for the management of primary hyperparathyroidism depends on the severity of the disease and its complications at the time of diagnosis, the specific situation of each patient and his/her natural history, and assessment of the risk/benefit ratio for each method (surgery, local destruction or drugs). This chapter summarizes the indications for the treatment of primary hyperparathyroidism, based on the international literature available as of December 31, 2023.

Adrenocortical carcinoma is a malignant tumor with a poor prognosis and a frequent metastatic extension. In very rare cases, a cardiac metastatic disease may occur, and surgical resection is essential for its management. MR-guided stereotactic radiotherapy is an attractive radiotherapy modality for the treatment of mobile thoracic tumors, enabling the target to be monitored continuously during irradiation, while the dosimetric plan can be adapted daily if necessary.

Objective: When transsphenoidal surgery (TSS) does not cure Cushing's disease (CD), 4 treatments are available: drug treatment (DT), second TSS (2nd TSS), bilateral adrenalectomy (BA), and pituitary radiotherapy (PR). DT is attractive but supposes long-term continuation, which we aimed to evaluate.

Design And Methods: Retrospective study, in a center prioritizing 2nd TSS, of 36 patients, including 19 with TSS failure and 17 with recurrence, out of 119 patients with CD treated by a first TSS, average follow-up 6.

Background: Adjuvant treatment with mitotane is commonly used after resection of adrenocortical carcinoma; however, treatment remains controversial, particularly if risk of recurrence is not high. We aimed to assess the efficacy and safety of adjuvant mitotane compared with surveillance alone following complete tumour resection in patients with adrenocortical carcinoma considered to be at low to intermediate risk of recurrence.

Methods: ADIUVO was a multicentre, open-label, parallel, randomised, phase 3 trial done in 23 centres across seven countries.

Article Synopsis
  • * The condition is characterized by specific symptoms related to a pituitary tumor, such as headaches and joint pain, and can lead to various complications including cardiovascular and metabolic issues.
  • * Diagnosis involves elevated IGF-I levels and imaging to identify the pituitary tumor; treatment typically starts with surgery, but medication and radiation may be necessary for some patients, and care is best administered by a specialized multidisciplinary team.

Prolonged exposition to supraphysiological doses of exogenous glucocorticoid eventually results in iatrogenic Cushing's syndrome, whose intensity depends on the dose and duration of the treatment and on individual susceptibility. In patients with chronic inflammatory diseases treated with oral glucocorticoids iatrogenic Cushing's is expected and recognized and it only imposes that the dose of glucocorticoid be maintained as low as possible and that there is no better alternative therapy available.In some cases, however, iatrogenic Cushing's syndrome may be unexpected by the prescribing physician as the true exposure to corticoids may depend largely on the patient: this is the case for topical steroids used in inflammatory skin diseases such as psoriasis.

Corticotroph tumor progression after bilateral adrenalectomy/Nelson's syndrome (CTP-BADX/NS) is a severe complication of bilateral adrenalectomy (BADX). The aim of our study was to investigate the prevalence, presentation and outcome of CTP-BADX/NS in patients with Cushing's disease (CD) included in the European Registry on Cushing's Syndrome (ERCUSYN). We examined data on 1045 CD patients and identified 85 (8%) who underwent BADX.

Article Synopsis
  • Pheochromocytoma/neuroblastoma composite tumors are rare and poorly understood, with limited information available about them.
  • The report highlights a unique case of a 39-year-old man who developed a composite tumor in his bones, seven years after having undergone surgery for adrenal neuroblastoma.
  • Diagnosing peripheral neuroblastic tumors in adults is challenging, especially for composite types, and there is no standard treatment approach, leading to complex discussions about the best management options.

Context: Ectopic acromegaly is a consequence of rare neuroendocrine tumors (NETs) that secrete GHRH. This abnormal GHRH secretion drives GH and IGF-1 excess, with a clinical presentation similar to classical pituitary acromegaly. Identifying the underlying cause for the GH hypersecretion in the setting of ectopic GHRH excess is, however, essential for proper management both of acromegaly and the NET.

Cushing's syndrome is defined by prolonged exposure to glucocorticoids, leading to excess morbidity and mortality. Diagnosis of this rare pathology is difficult due to the low specificity of the clinical signs, the variable severity of the clinical presentation, and the difficulties of interpretation associated with the diagnostic methods. The present consensus paper by 38 experts of the French Society of Endocrinology and the French Society of Pediatric Endocrinology and Diabetology aimed firstly to detail the circumstances suggesting diagnosis and the biologic diagnosis tools and their interpretation for positive diagnosis and for etiologic diagnosis according to ACTH-independent and -dependent mechanisms.

Background And Objective: It has been reported recently in a cross sectional study that patients with amiodarone induced thyrotoxicosis (AIT) showed a 'white' thyroid on unenhanced computed tomography, due to intrathyroid iodine accumulation. However, the link between increase in thyroid radiologic density and amiodarone induced thyrotoxicosis remains unknown. We sought to analyze this link.

The discovery of microRNAs (miRNAs) in 1993 has challenged the dogma of gene expression regulation. MiRNAs affect most of cellular processes from metabolism, through cell proliferation and differentiation, to cell death. In cancer, deregulated miRNA expression leads to tumor development and progression by promoting acquisition of cancer hallmark traits.

Article Synopsis
  • Pregnant women with high cortisol levels (hypercortisolism) have a higher chance of having babies early (prematurity) and may face health issues later, like high blood pressure or diabetes.
  • A study looked at 60 women with a history of Cushing's disease to see how their cortisol levels affected their pregnancies.
  • Results showed that women with high cortisol during pregnancy had a high risk of early births, and those not having normal cortisol levels were more likely to have complications, so doctors need to keep a close watch on them.

Article Synopsis
  • Cushing's disease can lead to a serious problem called Nelson's syndrome after a certain surgery (BADX), but we don’t know enough about it and how to treat it well.
  • Researchers looked at a lot of studies to learn about how common this problem is and how different treatments work.
  • They suggest regular scans (like MRIs) after surgery to keep an eye on things, and they believe that surgery should be the first option to treat new tumors if they show up.
