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,...

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)....

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...
