Molecular Basis of Aggressiveness in Pituitary Adenomas and Its Association With the Immune Microenvironment

International Journal of Genomics, Volume 2025, Issue 1, 2025.
Background: Pituitary adenomas (PAs) are common intracranial tumors, and their aggressive phenotype exhibits a poor prognosis. We aimed to explore the aggressive feature of PAs and discover novel diagnostic markers. Method: The datasets of GSE260487 and GSE169498, which contained invasive and noninvasive samples, were downloaded from the Gene ...

Advancements in Molecular Diagnosis and Pharmacotherapeutic Strategies for Invasive Pituitary Adenomas

Immunity, Inflammation and Disease, Volume 12, Issue 12, December 2024.
ABSTRACT Background The overwhelming majority of pituitary tumors consist of pituitary adenomas (PAs), which have recently also been termed pituitary neuroendocrine tumors (PitNETs). Clinically significant PAs occur in approximately one in every 1000 individuals, while other types of pituitary tumors, such as craniopharyngiomas and pituicytomas, are ...

Untreated Giant Macroprolactinoma with Chronic Cerebrospinal Fluid Leakage: An Unusual Complication

Case Reports in Endocrinology, Volume 2019, Issue 1, 2019., 2019
Macroprolactinoma has the potential to cause base of skull erosion and often extends into the sphenoid sinus. Rapid shrinkage of this invasive tumor following dopamine agonist therapy has been postulated to cause unplugging of the eroded area, leading to cerebrospinal fluid leakage.

Visual morbidity in macroprolactinoma: A retrospective cohort study

Clinical Endocrinology, Volume 101, Issue 6, Page 648-658, December 2024.
Abstract Objective The management of visual field damage in patients with macroprolactinomas is a major therapeutic challenge. We aimed to study the visual morbidity associated with macroprolactinoma and its outcomes following medical and surgical treatment. We aimed to identify predictors of visual recovery. Methods We retrospectively reviewed patient'
