Context: Pituitary adenoma is generally indolent, but an aggressive subtype called atypical adenoma has uncertain prognosis, and an unclear relationship between prognosis and morphology.
Objective: This study investigated the prognostic factors of this tumor. Design: Retrospective analysis. Setting: University and associated hospitals.
Observational Model: Case Control, Observational Model: Natural History, Time Perspective: Cross-Sectional, Time Perspective: Retrospective
Active, not recruiting

Several studies have been reported that heart rate is known to be associated with prognosis in chronic diseases and acute diseases. For example, a decrease in heart rate following myocardi...
The purpose of the study is to determine genetic links among blood-relatives and between spouses of patients with pituitary tumors.
The purpose of this study is to observe predictors of pituitary tumor recurrence and markers of persistent disease activity through computerized collection of comprehensive demographic, th...
This is a phase II, open-label, 12-month pilot study in 10 patients with silent corticotroph pituitary tumors testing the hypotheses that Pasireotide LAR treatment of patients with silent ...
A study to followup patients that have previously been treated for pituitary tumours with either photodynamic therapy or placebo in a previous trial. The study aims to determine whether ph...
The sellar and parasellar region is a complex anatomical area in which several diseases may develop. The pituitary gland may be affected by a wide range of conditions having similar clinical character...
Pituitary stalk interruption syndrome (PSIS) is characterised by a thin or absent pituitary stalk usually in association with an ectopic posterior pituitary and hypoplasia/aplasia of the anterior pitu...
Ectopic pituitary adenomas (EPAs) are rare, and the suprasellar cistern seems to be the most common location. At this time, no detailed original classification, diagnosis, or treatment protocols for s...
Pituitary carcinomas are rare neoplasms whose designation requires demonstration of metastatic disease. No specific morphologic features can reliably distinguish pituitary carcinomas from pituitary ad...
Nonfunctioning pituitary adenomas (NFPAs) are the most frequent pituitary tumors.
Disorders involving either the ADENOHYPOPHYSIS or the NEUROHYPOPHYSIS. These diseases usually manifest as hypersecretion or hyposecretion of PITUITARY HORMONES. Neoplastic pituitary masses can also cause compression of the OPTIC CHIASM and other adjacent structures.
Peptides, natural or synthetic, that stimulate the release of PITUITARY HORMONES. They were first isolated from the extracts of the HYPOTHALAMUS; MEDIAN EMINENCE; PITUITARY STALK; and NEUROHYPOPHYSIS. In addition, some hypophysiotropic hormones control pituitary cell differentiation, cell proliferation, and hormone synthesis. Some can act on more than one pituitary hormone.
Increased levels of PROLACTIN in the BLOOD, which may be associated with AMENORRHEA and GALACTORRHEA. Relatively common etiologies include PROLACTINOMA, medication effect, KIDNEY FAILURE, granulomatous diseases of the PITUITARY GLAND, and disorders which interfere with the hypothalamic inhibition of prolactin release. Ectopic (non-pituitary) production of prolactin may also occur. (From Joynt, Clinical Neurology, 1992, Ch36, pp77-8)
Neural tissue of the pituitary gland, also known as the neurohypophysis. It consists of the distal AXONS of neurons that produce VASOPRESSIN and OXYTOCIN in the SUPRAOPTIC NUCLEUS and the PARAVENTRICULAR NUCLEUS. These axons travel down through the MEDIAN EMINENCE, the hypothalamic infundibulum of the PITUITARY STALK, to the posterior lobe of the pituitary gland.
Neoplasms which arise from or metastasize to the PITUITARY GLAND. The majority of pituitary neoplasms are adenomas, which are divided into non-secreting and secreting forms. Hormone producing forms are further classified by the type of hormone they secrete. Pituitary adenomas may also be characterized by their staining properties (see ADENOMA, BASOPHIL; ADENOMA, ACIDOPHIL; and ADENOMA, CHROMOPHOBE). Pituitary tumors may compress adjacent structures, including the HYPOTHALAMUS, several CRANIAL NERVES, and the OPTIC CHIASM. Chiasmal compression may result in bitemporal HEMIANOPSIA.
