Background:
- Lab studies help researchers better understand cancer biology. This information may lead to new methods for diagnosing or treating cancer. To develop these studies, researchers want to collect samples from people with cancer or precancer conditions of the lymph system. These conditions include multiple myeloma, different types of lymphoma, and adult leukemia/lymphoma. The samples collected will include blood, urine, bone marrow, and tumor and skin tissue.

Urinary Vitamin C Loss in Diabetic Subjects
Recruiting
Several studies have reported that diabetic subjects have lower plasma vitamin C concentrations than non-diabetic subjects. Although urinary vitamin C loss in diabetic subjects was reported to be increased in two studies, these are difficult to interpret due to lack of controlled vitamin C intake, inadequate sampling, lack of control subjects, or methodology uncertainties in vitamin C assay and sample processing. Consequently, it is unclear whether diabetic subjects truly have both low plasma an... Read More

Natural History Study of Progressive Multifocal Leukoencephalopathy (PML)
Recruiting
Background:
- Progressive multifocal leukoencephalopathy (PML) is a severe viral infection of the brain. It is caused by JC virus. Many people have this virus in their bodies all their life, but it is usually kept in check by their immune system. If the immune system does not work right because of a disease or medication, the virus becomes active and can damage cells in the brain. Not much is known about PML or how it affects the immune system. Researchers want to study people with PML to bette... Read More

Natural History of Familial Carcinoid Tumor
Recruiting
This study will evaluate members in families with a history of small bowel carcinoid cancer to study the natural history of those family members that have the disease, determine ways to improve early detection by performing surveillance on those at risk but without disease and to identify the gene(s) that may cause the tumors. Familial carcinoid tumors usually originate in hormone-producing cells that line the small intestine or other cells of the digestive tract. The tumors are slow-growing and... Read More

A Multi-Center Natural History of Urothelial Cancer and Rare Genitourinary Tract Malignancies
Recruiting
Background:
Tumors in the genitourinary tracts can occur in the kidney, bladder, prostate, and testicles and can have common and rare histologies. Some cancers that occur along the genitourinary (GU) tract are rare. Some GU tumors are so rare that they are not included in treatment studies or tissue banks. This makes it hard for researchers to determine standards of care. Researchers want to learn more about common and rare GU tumors.
Objective:
To learn more about urinary tract cancers.

Focal Therapy With Stereotactic Body Radiation Therapy (SBRT) for Patients With a Single Prostate Tumor
Recruiting
Background:
The current standard treatment of prostate cancer is either surgery or radiation. Typically, this includes either the removal or radiation of the whole prostate gland. Many people now seek out focal therapy options to decrease the side effects of treatment. Until now, several forms of physical destruction with heat (thermal ablation), cold (cryotherapy), sound waves (HIFU), laser (FLA), and electrical energy (IRE). A new type of radiation (SBRT) may be an effective way to cure men o... Read More

A Study of Therapeutic Drug Monitoring-Based Atezolizumab Dosing
Recruiting
Background:
A type of drug called monoclonal antibody immune checkpoint inhibitors are often used in cancer treatment. These drugs help the body s immune system fight cancer by blocking proteins that cause cancer cells to grow. One of these drugs (atezolizumab) is approved to treat certain cancers. Researchers want to find out if lower doses of this drug might provide the same benefit with fewer adverse effects.
Objective:
To test different doses and timing of atezolizumab for people with can... Read More
