Brief Summary

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. Eligibility: People ages 18 and older with urinary tract or GU cancer such as bladder, kidney, testicular, prostate, penis, or neuroendocrine cancer. Design: Participants will be screened with questions about their medical history. Their medical records will be reviewed. Participants will have a physical exam. They will give blood and urine samples. They will complete a survey about their family cancer history. Clinical photographs will be taken to document skin lesions. Participants may have imaging scans of their chest, abdomen, and pelvis. They may have a contrast agent injected into their arm. Participants will get recommendations about how to best manage and treat their cancer. They can ask as many questions as they would like. Participants will provide existing tumor samples if available. They may have optional tumor biopsies up to twice a year. For needle biopsies, the biopsy area will be numbed and they will get a sedative. A needle will be inserted through their skin to collect a tumor sample. For skin biopsies, their skin will be numbed. A small circle of skin will be removed. Some blood and tumor samples may be used for genetic tests. Participants will have frequent follow-up visits. If they cannot visit NIH, their home doctor will be contacted. They will be followed on this study for life....
