Official Title:	Multidisciplinary Etiologic Study Of Familial Testicular Cancer

Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:

Ascertain new families with familial testicular germ cell tumors (TGCT)
Characterize the clinical features (phenotype) of familial TGCT with data acquired through medical history, physical examination, dysmorphology examination, imaging studies, and laboratory samples
Underlying genetic mechanism for susceptibility to TGCT in families by genome-wide linkage analysis, dense genotyping marker panels targeted at candidate regions, positional cloning, candidate gene testing through collaboration with the International ...
Evaluate various parameters related to psychosocial and behavioral issues resulting from being a member of a family at increased risk of TGCT by assessing genetic knowledge, interest in genetic testing, reproductive decision-making, quality of life, ...
Create a repository of biological samples from members of high-risk families for subsequent etiologic and translational research by collection of serum, plasma, whole blood, DNA, semen, and tumor tissue

Estimated Enrollment:	750
Study Start Date:	May 2002
Estimated Primary Completion Date:	December 2015 (Final data collection date for primary outcome measure)

Detailed Description:

OBJECTIVES:

Identify new families with familial testicular germ cell tumors (TGCT).
Determine the clinical features of familial TGCT.
Determine the underlying genetic mechanism for susceptibility to familial TGCT.
Determine the various parameters related to psychosocial and behavioral issues resulting from being a member of a family at increased risk of TGCT.

OUTLINE: This is a two-part study.

Part 1 (genetic study): Participants contribute DNA for analysis. Participants also complete personal and family medical history, risk factor exposure, and psychosocial and behavioral questionnaires.
Part 2 (etiology study): Participants undergo clinical evaluation including physical exam, blood tests, and imaging studies (CT scan or MRI and ultrasound) of the chest, abdomen, pelvis, and gonads.

A certificate of confidentiality protecting the identity of research participants in this project has been issued by the National Cancer Institute.

Participants do not receive the results of the genetic analysis, which is aimed at finding new testicular cancer susceptibility genes. The results do not influence the type or duration of treatment. Genetic testing for mutations in known genes cannot be performed, as none of these genes have yet been identified.

Participants are followed annually for 5 years.

PROJECTED ACCRUAL: Approximately 750 participants will be accrued for this study within 5 years.

- A single family member with bilateral testicular cancer
- Men with a history of TGCT who are one in a set of identical siblings
  - The unaffected identical sibling must also agree to participate in the study
TGCT case defined as histologically confirmed germ cell-derived tumor arising in the testis
