Generously supported by IPSEN)-->It is known that acromegaly is associated with increased risk of benign and malignant tumours. Previous studies show the prevalence of nodular thyroid disease in 40–70% of patients with acromegaly, and a 5–7% prevalence of thyroid cancer in these patients, which is higher compared to the general population.Latvian Cancer Register data show an incidence of thyroid cance...

Full gene coding sequence of somatostatin receptor 5 and 2000 bp of upstream region was estimated using direct sequencing in 28 patients with acromegaly and 97 controls. Total 19 polymorphisms were identified (SNP1-19) and possible haplotypes were reconstructed. From all polymorphisms found silent substitution SNP15 was significantly associated with acromegaly as compared with control group (P=0.005). Another substitution SNP17 involves the amino acid change from prolin...

Pituitary adenomas (PA) are benign tumors that develop in pituitary gland. Hormone secreting PA can cause overproduction of pituitary hormones leading to different systemic endocrine disorders (acromegaly, Cushing’s disease and others). Non-secreting PA can promote headaches (stretching of the dural sheath) and visual field defects (chiasma compression). We managed to obtain resected tumor samples from the patient having non-secreting PA, first tumor was resected in 2010,...

Pituitary neuroendocrine tumors (PitNETs) are non-metastatic neoplasms of the pituitary that may overproduce hormones leading to systemic disorders or tumor mass effects causing headache, vertigo, or visual impairment. The overall estimated clinical prevalence of PitNETs is 1 in 400 to 1 in 1000 people. Although the pathogenesis of PitNETs has been extensively studied the molecular factors underlying tumorigenesis, remission, and therapy response of PitNETs are still unclear. ...

Introduction: Pituitary adenomas (PA) are tumours of the anterior pituitary. Despite the benign nature these neoplasms cause increased mortality and morbidity. Clinically relevant PAs affect around 0.1% of population during their lifetime. Currently, there is no human PA cell culture models. Tissue cultures derived from PA surgery materials depending on harvesting conditions can form free floating aggregates called pituispheres (PS) or adherent mesenchymal stromal cells (MSC)....

Introduction: EDIs with LAN-ATG therapy may help improve the burden associated with long-term acromegaly management. The LEAD study evaluated the efficacy and safety of this approach by switching from OCT-LAR conventional dosing to LAN-ATG EDI.Methods: LEAD was a multinational, multicentre, open-label, non-comparative study. Acromegalic patients with normal IGF1 after OCT-LAR 10 or 20 mg injections every 4 weeks for ≧6 months were switched to LAN-...

Objective: The most common type of pituitary diseases are pituitary adenomas (PA) of different origin. Although non-metastasizing, they still cause increased mortality and morbidity. Clinically significant PAs affect around 0.1% of population during lifetime. Circulating cell free DNA (ccfDNA) is approximately 165 bp long DNA fragments which are released in bloodstream upon cell death. ccfDNA has been used to investigate presence and properties of various cancers. Data on ccfD...
