Brief Summary

The incidence of testicular germ cell tumors, the most common cancer in men aged 15 to 45 years, has doubled in France in 30 years. Reasons remain unclear but a role of environmental factors, especially during critical periods of development, is strongly suspected. Reliable data on environmental exposure during this critical period are sparse.The discordant findings and the limitations of available studies underline the importance to conduct studies with sufficient statistical power to detect risk due to exposures during critical windows of vulnerability. We conduct a multicentric case-control study to assess this association. Cases and controls will be enrolled during a 18-month period. They will be interviewed by professional telephone interviewers about their occupational and residential history and about their domestic exposure to pesticides and other nuisances. An optional biological study to assess genetic polymorphisms known to be associated with testicular cancer will be proposed to every cases and controls. Mothers (or close relative) of cases and controls will also be contacted (with son's agreement). If they agree to participate, they will also be interviewed about antenatal and early life exposure of their sons to pesticides and other nuisances. Cases will be matched up with 2 controls (one of each group) both on age (+/- 2 years) and on recruiting center.

Outcome Measures

Primary Outcomes (1)

  • Assess the association between pesticide exposure during Antenatal and Early Postnatal Periods and the risk of testicular cancer during adulthood

    Occupational, environmental and domestic exposures to pesticides and other nuisances will be assessed.

    at the end of enrollment (18 months)

Secondary Outcomes (2)

  • Assess the association between a combined exposure to pesticides and the risk of testicular cancer during adulthood

    at the end of enrollment (18 months)

  • Analyse polymorphisms known to be associated with testicular cancer risk to explore gene-environment interactions

    one year after the end of enrollment

Study Arms (3)

Cases: testicular cancer patients

Other: Phone interview and blood test

Group A controls

Other: Phone interview and blood test

Group B controls

Eligibility Criteria

Age18 Years - 44 Years
Sexmale
Healthy VolunteersYes
Age GroupsAdult (18-64)
Sampling MethodNon-Probability Sample
Study Population

Cases are patients with a testicular germ cell tumor. They will be recruited in the French infertility centers at the moment of sperm cryopreservation. Group A controls are sperm donors and husbands of women with fertility troubles. They will be recruited in the French infertility centers and in the medically assisted procreation centers. Group B controls are husbands of women followed for a pathological pregnancy. This group of controls will be recruited in the level III maternities.

You may qualify if:

  • Men aged between 18 and 44 years old
  • Born in metropolitan France
  • Able to understand, read and write French
  • Without any psychiatric and severe cognitive disorder
  • Willingness to participate to the study
  • Who has signed and dated an inform consent form
  • Affiliated to a health care system

You may not qualify if:

  • Who has a legal guardian
  • History of testicular germ cell tumor or cryptorchidism (only for controls)
