This is an open label, intra-patient dose escalation, to evaluate ADI-PEG 20, in combination with Temozolomide (TMZ) and radiation therapy (RT) in children, adolescents and young adult patients with newly diagnosed high grade glioma (HGG).

Background: Primary central nervous system (CNS) tumors grow in the brain and spinal cord. These tumors are rare, but they are difficult to treat and often fatal. SmartMatch is a new technology that tries to help find the best medicines for the particular tumor by testing how small pieces of surgically removed tumor tissue react to different drugs. The study team wants to see if SmartMatch can complete the analysis and generate a report within 21 days from the time of the surgery. Objective: To better understand CNS tumors so doctors can find better ways to treat them in the future. Eligibility: People aged 15 years and older with recurrent CNS tumors. Patient must already be scheduled for a surgery for the tumor at the NIH. Design: The study team will collect a small amount of tumor samples during the planned surgery. They may also use tumor samples from previous procedures. No new or additional procedures will be done for the purpose of this study. The tumor samples will be sent to a lab for SmartMatch analysis. Once completed, the results will be shared with the patient and his/her local doctor. Together they can decide whether to incorporate the results into the treatment plan. It is important to know that the results may or may not be helpful. There will only be one blood test for research. Blood and tissue samples collected may be used for additional analysis. Tumor tissue may be used to grow additional samples for further study. Participants will receive a pathology diagnosis and mutation profile generated by pathologists who specialize in CNS tumors. The study team will seek updates on participant's health approximately every 6 months for 3 years. Tumor samples may also be collected from any additional surgery done at NIH during this time.

The goal of this clinical trial is to learn if the combination of cemiplimab and fianlimab can improve outcomes compared to cemiplimab alone in adults with Human Papillomavirus Positive HPV-positive head and neck cancer.

This phase II trial studies whether providing cancer treatment in the home is preferred over the traditional clinic setting and if it improves treatment satisfaction in cancer patients living in the Florida Panhandle and surrounding areas. Typically, drug-related cancer care is provided at a medical center which causes patients to have to spend considerable time away from their family, friends, and familiar surroundings. This may add to the physical, emotional, social, and financial burden for patients and their families during this difficult time in their lives. The Cancer Connected Access and Remote Expertise (CARE) Beyond Walls (CCBW) program uses a specialized care team trained to provide cancer treatment in the patient's home setting. It is designed to support remote connection between the home health team and providers and Mayo clinic. This may be preferred over the traditional clinic setting which may improve treatment satisfaction in cancer patients living in the Florida Panhandle and surrounding areas.

The study will evaluate patient and Health Care Professional- reported preference for Subcutaneous (SC) compared with IV nivolumab administration or similarly for SC compared with IV pembrolizumab.

The researchers are doing this study to find out whether the radiopharmaceutical therapy (RPT) 177Lu-PSMA-617 is a safe treatment for people with IDH wild type glioma.

This is a single-site, single-arm, prospective, interventional cohort study using intraoperative ultra-rapid droplet digital polymerase chain reaction (UR- ddPCR) to assess residual IDH1-mutant tumor at the end of surgical resection and, if positive, guide additional resection in real-time.

Glioblastoma is an infiltrating tumor that is difficult to visualize in surgery and on standard images. A special pH (acid-base) related magnetic resonance imaging (MRI) has been developed to better see infiltrating tumor. In this safety study, the investigators will carry out increased levels of pH based resections of infiltrating tumor to assess the tolerability in VA populations.

High-grade gliomas (HGGs) are among the most aggressive and treatment-resistant brain tumors. Immunotherapy with checkpoint inhibitors like nivolumab has shown promise, but its efficacy remains variable and poorly understood in this patient population. This clinical trial investigates a novel imaging-enabled formulation of nivolumab-IRDye800 (nivo800) which incorporates a near-infrared (NIR) fluorescent dye to enable real-time visualization of drug distribution within tumor tissue.

The goal of this clinical trial is to evaluate the safety and feasibility of focused ultrasound (FUS)-mediated blood-brain barrier (BBB) disruption using the Next Generation Dome Helmet (NGDH) in adults with glioblastoma (GBM) undergoing the maintenance phase of the standard "Stupp protocol". Participants will: * Undergo repeated FUS BBB disruption treatments during the maintenance phase of temozolomide (TMZ) chemotherapy. * Receive intravenous ultrasound contrast (DEFINITY®) prior to each FUS session to facilitate targeted BBB disruption. * Undergo serial MRI scans and clinical assessments to evaluate safety and the extent of BBB opening. * Provide blood samples (and tumor tissue if available) for biomarker analysis related to BBB permeability, tumor presence, and treatment response. * Be followed for progression-free survival (PFS) and overall survival (OS) during routine neuro-oncology visits until end of life.

This is a prospective study involving human participants. Pressure and stretch sensitivity measures between oral cancer patients and healthy subjects will be compared. Pain stimulation will be conducted on the site of the cancer in 40 oral cancer patients, and on the tongue in 40 healthy volunteers, using pressure and stretch sensitivity tests.

The purpose of this study is to evaluate the safety and feasibility of intra-operative microperfusion during a planned neurosurgical resection of diseased brain parenchyma, including either an epileptic focus requiring temporal lobectomy or a glioma. Devices used for microperfusion are Joanneum Research cerebral open flow microperfusion (OFM) catheters, push and pull tubing, and MPP102-II pump.
