The Upregulation of Molecules Related to Tumor Immune Escape in Human Pituitary Adenomas

Frontiers in Endocrinology, 2021
Human pituitary adenomas are one of the most common intracranial neoplasms. Although most of these tumors are benign and can be treated medically or by transsphenoidal surgery, a subset of these tumors are fast-growing, aggressive, recur, and remain a ...

Coexistence of Pituitary Adenoma and Primary Pituitary Lymphoma: A Case Report and Review of the Literature

Frontiers in Surgery, 2022
In the pituitary sella, the coexistence of pituitary adenoma and primary pituitary lymphoma is exceedingly rare. Thus far, only six cases have been reported. Here, we present the seventh case of coexisting pituitary adenoma and primary pituitary lymphoma,

Corticotroph Aggressive Pituitary Tumors and Carcinomas Frequently Harbor ATRX Mutations

Journal of Clinical Endocrinology and Metabolism, 2020
Context Aggressive pituitary tumors (APTs) are characterized by unusually rapid growth and lack of response to standard treatment. About 1% to 2% develop metastases being classified as pituitary carcinomas (PCs).

Evaluation and Current Clinical Progress of Invasiveness in Postoperative Residual Regrowth and Recurrence of Pituitary Adenoma

Zhongliu Fangzhi Yanjiu, 2022
Pituitary adenoma is one common type of intracranial tumors, accounting for about 10% of intracranial tumors. Although pituitary adenomas are benign tumors, the complete resection and recurrence prevention remain challengeable due to aggressive growth of

Pituitary tumors and the risk of other malignancies: is the relationship coincidental or causal?

Endocrine Oncology, 2023
Pituitary adenomas are benign neoplasms of the pituitary. The most prevalent are prolactinomas and non-functioning pituitary adenomas, followed by growth hormone-and ACTH-secreting adenomas.
