Prepubertal Testicular Tumor Registry.

The Prepubertal Testicular Tumor Registry has been in existence for 12 years. Information on 327 patients was collected and registered in the database. Demographic data have been analyzed, leading to a better understanding of these rare tumors. Information regarding the natural history and behavior of the tumors has also evolved from a retrospective review of the tumors. The registry will continue in an effort to collect centrally information on these unusual tumors and to attempt to aid in developing a better understanding of the natural history and behavior of the tumors to provide early detection, consistent treatment and improved survival.
