Clinical Trials

The purpose of this research is to evaluate the diagnostic role and clinical efficacy of [18F]FET-PET/MRI in detecting MRI-occult primary or residual/recurrent functional pituitary adenomas (PAs) and its influence on clinical and surgical decisions.

The intent is to collect relevant clinical data on patients exposed to Agent Orange plus assessment of the tissue for genetic mutations known to be associated with growth of thyroid cancer and pituitary tumors and report our findings as a descriptive case series.

The purpose of this study is to evaluate the effectiveness and safety of  ATR-101 for the treatment of adults who have internally caused Cushings syndrome.

The purpose of this study is to investigate if a blood test measuring copeptin within 24 hours following pituitary surgery could predict development of diabetes insipidus (increased urination and thirst with fluid balance problems) as opposed to the clinical methods we currently use.

The purpose of this data registry involves the collection of standard of care clinical treatment regimens, diagnostic information and surgical outcomes which may include human specimens and associated genomewide expression data.  

The purpose of this study is to combine recent advances in ultrasound imaging, specifically an endonasal transducer array and contrast enhanced ultrasound, to offer an intraoperative image-guided solution for lesion-specific surgical resection to impact clinical outcome. 

The purpose of this study is to evaluate the performance [sensitivity, specificity, accuracy] of 18Fluoro-O-(2) fluoroethyl-L-tyrosine (FET) PET/CT imaging to detect ACTH-secreting pituitary adenoma, using operative findings and histopathology as truth standard.

The objectives of this study are to survey patients during the post-operative period regarding their experience with fluid restriction including adherence and discomfort, and to document rates of hyponatremia and readmissions in post-operative patients.

Advances in endonasal, endoscopic transsphenoidal surgical techniques have decreased complications and length of stay for persons undergoing resection of sellar and suprasellar masses  Previous research by investigators now at Mayo (SLS, AQH) has shown that particular interventions including fluid restriction post-operatively decrease patient morbidity (e.g., from hyponatremia) and readmissions while maintaining patient safety. However, the patient perspective on the impact of fluid restriction has not ...

The objectives of this study are to:

• • Measure the short and long-term overall and nasal-specific quality of life (QOL) impact of patients undergoing Endoscopic Endonasal Skull Base Surgery (EESBS) for pituitary and sellar lesions.
  • Determine the relative difference in QOL impact of EESBS for patients undergoing surgery for functional and nonfunctional pituitary adenomas.
  • Generate baseline data to development and validate a site-specific endoscopic-specific comprehensive QOL for EESBS.
  • Particular tumors of interest include pituitary tumors, Rathke’s cleft cysts, craniopharyngiomas, clival chordomas and chondrosarcomas.
  • Specific QOL aims focus on olfaction (sense of smell), gustation (sense of taste) and nasal function.

The purpose of this study is to determine return to baseline (RTB) period after an elective craniotomy procedure using the ImPACT testing assessment.

Biospecimen banks are a modern attempt to centralize collections of human blood and tissue samples along with health information and personal history. The Neuro-Oncology Program Registry and Biobank will be used for research purposes to increase our understanding of nervous system tumors.
