The Molecular Pathogenesis of Pituitary Adenomas: An Update
نویسندگان
چکیده
Pituitary tumors represent the most common intracranial neoplasms accompanying serious morbidity through mass effects and inappropriate secretion of pituitary hormones. Understanding the etiology of pituitary tumorigenesis will facilitate the development of satisfactory treatment for pituitary adenomas. Although the pathogenesis of pituitary adenomas is largely unknown, considerable evidence indicates that the pituitary tumorigenesis is a complex process involving multiple factors, including genetic and epigenetic changes. This review summarized the recent progress in the study of pituitary tumorigenesis, focusing on the role of tumor suppressor genes, oncogenes and microRNAs.

Endoscopic Endonasal Transsphenoidal Approach for Pituitary Adenomas: a Prospective Review of Our Early Experience
Background & Aim: Pituitary adenomas are a part of a dissimilar group of benign neoplasms. The development of endoscopic techniques for surgery of paranasal sinuses has increased the opportunity for an endoscopic approach with regard to the pituitary gland. Minimally invasive endoscopic pituitary surgery, in turn, permits a more thorough tumor resection and fewer associated surgical complicatio...

Introduction: The endoscopic transsphenoidal approach for pituitary adenomas and other sellar lesions is quickly becoming the procedure of choice in their surgical management. The most common approach is binostril three-hand technique which requires a large exposure and subjects both nasal cavities to potential trauma. To reduce nasal morbidity, we employ a mononostril two-hand technique with t...

Pituitary adenomas comprise 10% of intracranial tumors and occur in about 20% of the population. They cause significant morbidity by compression of regional structures or the inappropriate expression of pituitary hormones. Their molecular pathogenesis is unclear, and the current classification of clinically nonfunctional tumors does not reflect any molecular distinctions between the subtypes. T...

متن کاملThe role of Notch and Hedgehog signaling pathways in pituitary development and pathogenesis of pituitary adenomas.
Pituitary adenomas are usually benign tumors that cause symptoms by compression of surrounding structures or impaired hormone secretion. Treatment, whether surgical or medical depends, on the tumor subtype and degree of compression; however, a significant proportion of patients do not achieve optimal control of mass effects or hormonal hypersecretion. Unraveling the pathogenesis of pituitary ad...
