1. At least 200 cases of ovarian cancer and 200 controls, with DNA samples available for genotyping. The controls must be broadly from the same population as the cases. Cases may be selected by age or family history.
  2. At least 200 invasive cases with follow-up and data on overall survival.

Ideally, the case-control sets will have phenotypic and epidemiological covariate data listed in the core variable list. Studies with more limited data may also be acceptable (e.g. those with limited data for controls):
