Researchers at the National Cancer Institute are collecting tissue and blood samples from people who have or may have kidney, bladder, prostate, testis, or penile cancer. By studying these samples, scientists hope to understand the genetic changes that cause these cancers and develop better treatments. This is not a treatment study—it's a research collection effort that helps build knowledge for future patients.
Kidney, bladder, and related cancers account for a significant portion of cancer diagnoses and deaths in the United States. By understanding the genetic basis of these cancers, researchers can develop targeted therapies and better treatment options. This long-running study (since 1982) has already led to FDA-approved drugs, and researchers want to continue this important work.
You likely qualify if…
You likely don't qualify if…
If you qualify, you would be asked to provide tissue samples (such as from a biopsy or surgery) and blood samples. Researchers may also ask about your medical history and quality of life. Family members may be asked to provide blood samples only. There is no set time limit—this is an ongoing research collection study, so your involvement would be determined with your research team at the clinic.
