Biomarkers of Pituitary Neoplasms: A Review (Part II)

Neurosurgery, 2010
Several new markers have shown a capacity to predict the clinicopathological behavior of pituitary neoplasms; these markers have shown potential to correlate with tumor subtype and size and patient age and sex. These various markers are involved in a host of cellular functions, including cell-cycle progression, cell proliferation, apoptosis, cell ...

Psychological changes associated with giant pituitary neoplasms.

Archives of Neurology And Psychiatry, 1955
Although nearly 600 articles concerning pituitary adenomas and craniopharyngiomas have been listed in the Quarterly Cumulative Index Medicus since its first volume, in 1916, only 13 are primarily concerned with the psychological changes which these lesions may produce if they expand upward to an unusual size.

Pituitary Neoplasms in two Horses

Zentralblatt für Veterinärmedizin Reihe A, 2010
SummaryTwo pituitary adenomas in older geldings are described: a chromophobe adenoma with severe acute hemorrhages among the neoplastic cells and an adenoma originating from the pars intermedia with a lesser degree of disseminated recent hemorrhages. Invasiveness was not observed, but, both tumors caused hemorrhages and pressure in the hypothalamic ...

Diagnosis and Management of Pituitary Adenomas: A Review.

Journal of the American Medical Association (JAMA), 2023
Importance Pituitary adenomas are neoplasms of the pituitary adenohypophyseal cell lineage and include functioning tumors, characterized by the secretion of pituitary hormones, and nonfunctioning tumors.

Pituitary Neuroendocrine Neoplasms

2020
Pituitary neuroendocrine tumors are a complex family of lesions that show a spectrum of differentiation based on their developmental regulatory transcription factors and hormone expression. They can cause a number of clinical syndromes such as acromegaly, Cushing disease, hyperprolactinemia, and hyperthyroidism or they may be clinically silent.

Genomics, Transcriptomics, and Epigenetics of Sporadic Pituitary Tumors.

Archives of Medical Research, 2023
Pituitary tumors (PT) are highly heterogeneous neoplasms, comprising functioning and nonfunctioning lesions. Functioning PT include prolactinomas, causing amenorrhea-galactorrhea in women and sexual dysfunction in men; GH-secreting adenomas causing ...

Xanthogranulomatous Hypophysitis Mimicking a Pituitary Neoplasm

Endocrine Pathology, 2004
Hypophysitis is an inflammatory disease of the pituitary gland that clinically and radiologically mimics pituitary tumors. We report here a case of xanthogranulomatous hypophysitis mimicking a pituitary neoplasm.A 65-yr-old woman presented with weight loss, fatigue, and visual disturbance.

MEDICAL TREATMENT OF PITUITARY NEOPLASM

JAMA: The Journal of the American Medical Association, 1925
The frequency of unsuccessful operations on tumors of the hypophysis has led us to search for a method of approach that is less hazardous. Two fields seemed open—that of glandular therapy and that of radiotherapy. The average benign enlargement of the pituitary gland will proceed along a certain stereotyped course.

Biomarkers of pituitary neoplasms.

Anticancer research, 2013
In a wide spectrum of tumors, cell proliferation, vascularity, apoptosis, cell adhesion, and cell-cycle progression may indicate tumor progression. In this review article, the literature regarding apoptotic markers and p53, as well as cyclooxygenase-2, galectin-3, and pituitary tumor-transforming factor, proliferative markers, angiogenesis, including ...
