Components of the canonical and non-canonical Wnt pathways are not mis-expressed in pituitary tumors. [PDF]
PLoS ONE, 2013 IntroductionCanonical and non-canonical Wnt pathways are involved in the genesis of multiple tumors; however, their role in pituitary tumorigenesis is mostly unknown.ObjectiveThis study evaluated gene and protein expression of Wnt pathways in pituitary ...

How to Classify Pituitary Neuroendocrine Tumors (PitNET)s in 2020
Cancers, 2020 Adenohypophyseal tumors, which were recently renamed pituitary neuroendocrine tumors (PitNET), are mostly benign, but may present various behaviors: invasive, “aggressive” and malignant with metastases.

The Microenvironment of Pituitary Tumors—Biological and Therapeutic Implications
Cancers, 2019 The tumor microenvironment (TME) includes resident and infiltrative non-tumor cells, as well as blood and lymph vessels, extracellular matrix molecules, and numerous soluble factors, such as cytokines and chemokines. While the TME is now considered to be

Anti-VEGF Therapy in Refractory Pituitary Adenomas and Pituitary Carcinomas: A Review
Frontiers in Oncology, 2021 Most pituitary tumors are considered benign adenomas, and only 0.1%–0.2% of them present metastasis and are defined as pituitary carcinomas (PCs). Refractory pituitary adenomas (PAs) lie between benign adenomas and true malignant PCs and are defined as ...

Experimental Evidence and Clinical Implications of Pituitary Adenoma Stem Cells
Frontiers in Endocrinology, 2020 Pituitary adenomas, accounting for 15% of diagnosed intracranial neoplasms, are usually benign and pharmacologically and surgically treatable; however, the critical location, mass effects and hormone hypersecretion sustain their significant morbidity ...
