EstimatedPlanned date reported by the registry; this milestone is not confirmed as achieved.
This study is being done to create a registry to help us learn more about germ cell tumors (GCT) and other testicular tumors. The registry will include people with these tumors and also relatives and unrelated people without these tumors. This study will help us learn more about the prevention, diagnosis, treatment and outcome of these tumors. Studying relatives of patients and people unrelated to patients with GCT and other testicular tumors will help us understand why some people get these tumors and why some people don't.

creation of a Germ Cell Tumor and testicular tumor registry
We will collect clinical data including diagnosis date, pathology, family history, and risk factors in patients with GCT-TT.
5 years
patients with testicular GCTs and non-GCT testicular tumors, extragonadal male GCTs, and female GCTs,
relatives of patients with GCTs or testicular tumors
healthy controls who are unrelated to Groups A or B and do not have a personal history of cancer nor a family history of GCT or non-GCT testicular tumors
A sample of blood or saliva will be obtained for DNA extraction. Approximately 2-4 tubes of blood will be collected or one tablespoon of saliva. If a participant has already provided a DNA sample for another MSKCC IRB approved protocol, they may not need to provide an additional sample.
At MSKCC, the following outpatient clinics will be used to recruit GCT and testicular tumor cases and controls: Urology (Department of Surgery), Gynecologic Oncology (Department of Surgery) Clinical Genetics, Genitourinary Oncology (Department of Medicine), and Gynecologic Medical Oncology (Department of Medicine).
