This clinical trial is studying solid tumor cancers. A solid tumor is one that starts in part of your body like your lungs or liver instead of your blood. Once they've grown bigger in one spot or spread to other parts of the body, they're harder to treat. This is called advanced or metastatic cancer. Participants in this study must have breast cancer or gastric cancer. Participants must have tumors that have HER2 on them. This allows the cancer to grow more quickly or spread faster. There are few treatment options for patients with advanced or metastatic solid tumors that express HER2. This clinical trial uses an experimental drug called disitamab vedotin (DV). Disitamab vedotin is a type of antibody drug conjugate or ADC. ADCs are designed to stick to cancer cells and kill them. This clinical trial uses a drug called tucatinib, which has been approved to treat cancer in the United States and some other countries. This drug is sold under the brand name TUKYSA®. This study will test how safe and how well DV with tucatinib works for participants with solid tumors. This study will also test what side effects happen when participants take these drugs. A side effect is anything a drug does to the body besides treating the disease.

This phase II/III trial examines whether patients who have undergone surgical removal of bladder, but require an additional treatment called immunotherapy to help prevent their bladder cancer from coming back, can be identified by a blood test. Many types of tumors tend to lose cells or release different types of cellular products including their DNA which is referred to as circulating tumor DNA (ctDNA) into the bloodstream before changes can be seen on scans. Health care providers can measure the level of ctDNA in blood or other bodily fluids to determine which patients are at higher risk for disease progression or relapse. In this study, a blood test is used to measure ctDNA and see if there is still cancer somewhere in the body after surgery and if giving a treatment will help eliminate the cancer. Immunotherapy with monoclonal antibodies, such as nivolumab and relatlimab, can help the body's immune system to attack the cancer, and can interfere with the ability of tumor cells to grow and spread. This trial may help doctors determine if ctDNA measurement in blood can better identify patients that need additional treatment, if treatment with nivolumab prolongs patients' life and whether the additional immunotherapy treatment with relatlimab extends time without disease progression or prolongs life of bladder cancer patients who have undergone surgical removal of their bladder.

This phase III trial compares the effect of stereotactic radiosurgery to standard of care memantine and whole brain radiation therapy that avoids the hippocampus (the memory zone of the brain) for the treatment of small cell lung cancer that has spread to the brain. Stereotactic radiosurgery is a specialized radiation therapy that delivers a single, high dose of radiation directly to the tumor and may cause less damage to normal tissue. Whole brain radiation therapy delivers a low dose of radiation to the entire brain including the normal brain tissue. Hippocampal avoidance during whole-brain radiation therapy (HA-WBRT) decreases the amount of radiation that is delivered to the hippocampus which is a brain structure that is important for memory. The drug, memantine, is also often given with whole brain radiotherapy because it may decrease the risk of side effects related to thinking and memory. Stereotactic radiosurgery may decrease side effects related to memory and thinking compared to standard of care HA-WBRT plus memantine.

The purpose of this study is to learn more about stroke and obtain information that may serve as the basis for future investigations. It will 1) establish a registry of patients with cerebrovascular disease (stroke); 2) characterize the natural history of acute stroke and transient ischemic attacks (TIA)-an interruption of blood flow to the brain that causes stroke symptoms for a short period of time); and 3) evaluate the data to generate ideas for future studies. Patients 18 years of age or older with suspected acute stroke or TIA may be eligible for this study. Subjects will be recruited from patients who present with stroke at the emergency department of Suburban Hospital in Bethesda, Maryland. The study will gather data collected from diagnostic and laboratory tests the patient undergoes as part of standard medical care, including findings of medical and neurological examinations and other tests. In addition, studies will be done for research purposes only to gather data about stroke and TIA. These may include the following: - Blood and urine tests not more than 2 tablespoons of blood will be drawn for various tests. - Electrocardiogram (EKG) (heart tracing)-electrodes placed on the chest wall detect the heartbeat and heart rhythm. - Computed tomography (CT) scan of the head-specialized X-rays are used to obtain images of the brain. - Magnetic resonance imaging (MRI) of the brain-a strong magnetic field and radio waves are used to produce images that provide information about the brain tissue and blood vessels. - Transcranial Doppler (TCD)-sound waves are used to image the arteries of the brain and neck. - Echocardiogram-sound waves are used to image the heart and evaluate heart function. Patients may be asked to return to Suburban Hospital for follow-up testing in 1, 3, and/or 12 months, when some of these tests may be repeated to assess changes over time
