Active clinical trials for "Pituitary Diseases"

To conduct a retrospective multicenter cohort study to define benchmark values for best achievable outcomes following transsphenoidal resection of pituitary adenomas.

The study aims to update current knowledge about the epidemiology of pituitary tumours (PiT), based on the wide body of scientific literature on new familial and/or syndromic forms. Although inherited predisposition is increasingly recognized, its clinical relevance in unselected series of PiT patients has not been specifically addressed. In addition, it is likely that further recognition of peculiar associations between PiT and other endocrine and/or non-endocrine neoplasia will further increase the spectrum of syndromic forms. Since the identification of inherited forms of PiT may have significant clinical implications in terms of patients management and familial screening, we aim to collect any relevant information in order to estimate their prevalence in a large unselected series of PiT patients and provide new clues for a modern clinical approach to these patients.

This study tried to highlight the predictive value of the morning postoperative cortisol levels, which can act as the prognosis value of the postoperative pituitary function, providing future medication advices for improving patients' safety of drugs.

Pituitary adenomas is a very common disease, but the cause and genetics hasn't been identified. The investigators are going to use genome-wide association study to identify genes that may be related to pituitary adenomas.

The major purpose of this study is to evaluate the changes of multiple organs in patients with growth hormone-secreting pituitary tumors before and after surgery. Plasma, DNA samples and pituitary tumor tissues will be kept for further analysis.

The purpose of the study is to determine genetic links among blood-relatives and between spouses of patients with pituitary tumors.

5-Aminolevulinic Acid (5-ALA) was approved by the FDA as an intraoperative optical imaging agent in patients with suspected high-grade gliomas (HGGs) in 2017. The investigators plan to administer 5-ALA to patients with pituitary tumors to demonstrate whether it can be used as an intraoperative optical imaging agent for this pathology. Overall, this pilot study will afford the overall opportunity to improve surgical management and advancement of the science of neurological and neuroendocrine disease.

Context: Pituitary adenoma is generally indolent, but an aggressive subtype called atypical adenoma has uncertain prognosis, and an unclear relationship between prognosis and morphology. Objective: This study investigated the prognostic factors of this tumor. Design: Retrospective analysis. Setting: University and associated hospitals.

The purpose of this study is to determine nasal resonance change after endoscopic endonasal transsphenoidal skull base surgery. Furthermore, the quality of voice is assessed, also.

Characterization of receptors present in non-functioning pituitary macroadenomas by Reverse Transcriptase- Polymerase Chain Reaction (RT-PCR) would assist with targeted medical therapy based on the information obtained by immunohistochemistry and RT-PCR.
