Clinical trials Below are current clinical trials.54 studies in Neurosurgery (open studies only). Filter this list of studies by location, status and more. Pituitary tumor registry Rochester, Minn. 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. Collection of Discarded Cerebrospinal Fluid for Research Purposes Rochester, Minn. The purpose of this study is to collect and store cerebrospinal fluid (CSF)from patients with normal CSF. This stored CSF will be used in the future as a culture media to better understand how therapeutic cells delivered into the CSF will behave. A Study Of Lutetium Lu 177 Dotatate (Lutathera®) In Patients With Inoperable, Progressive Meningioma After External Beam Radiation Therapy Rochester, Minn. The purpose of this study is to estimate the efficacy of LUTATHERA treatment in patients with recurrent grade 1 meningioma as measured by 6-month PFS rate, and to estimate the efficacy of LUTATHERA treatment in patients with recurrent grade 2 or 3 meningioma as measured by 6-month PFS rate. Intraoperative Contrast Enhanced Ultrasound for the Identification of Pituitary Adenoma in Cushing’s Disease Rochester, Minn. 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. Mayo Clinic Cancer Center Neuro-Oncology Program Registry And Biobank For The Study Of Nervous System Tumors Rochester, Minn. 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. A Study To Develop A Biorepository Of Blood Samples From Cancer Patients Participating In The Gemini (IRB 19-006717) Protocol Scottsdale/Phoenix, Ariz., Jacksonville, Fla. The purpose of this study is to develop a biorepository of blood samples from cancer patients participating in the Gemini (IRB 19-006717) protocol. These samples will be used for future biomarker discovery and other translational studies. A Study to Assess an MRI Image Localizer for 7T MRI Neuronavigation Rochester, Minn. The purpose of this study is to develop a localizer for use within the 7T MRI to allow for future clinical use in neurosurgical planning. A Study of Simulated Sylvian Fissure Dissection Under Subarachnoid Hemorrhage Conditions Using a Rodent Microvascular Anastomosis Model Rochester, Minn. The purpose of this study is to assess the differences in microvascular anastomosis outcomes between the experiment aneurysmal subarachnoid hemorrhage (aSAH)-like conditions and control animals. Minnesota Spinal Cord Injury Data Network Rochester, Minn. This is a study to generate feasibilty data regarding the collection of health and psychosocial outcomes after acquired spinal cord injury (SCI) A Study Of Paired-Vagus Nerve Stimulation On Functional Connectivity In Ischemic Stroke Rochester, Minn. The purpose of this study is to delineate the neural mechanisms of VNS-REHAB (Vagus Nerve Stimulation paired with task-specific upper limb rehabilitation).

The patient comes first. So the mission and research here is to advance how we can best help the patient, how to make sure the patient comes first in care. So in many ways, it's a cycle. It can start with as simple as an idea worked on in a laboratory, brought to the patient bedside, and if everything goes right — and let's say it's helpful or beneficial — then brought on as a standard approach. And I think that is one of the unique characteristics of Mayo's approach to research — that patient-centeredness — that really helps to put it in its own spotlight.
