Abstract

Historically, familial aggregation of breast cancer has been addressed either by genetic studies of extended pedigrees in which there are many cases of cancer, or by epidemiological case-control studies which measure family history by unverified self-reports of cancer in relatives. Recent identification of genetic loci involved in breast cancer susceptibility (BRCA1, p53), and recognition of the need to study the roles and interactions of genetic and environmental risk factors concurrently, have led to the development of case-control-family designs. We present here the aims, rationale and protocol for one such population-based study being conducted in Melbourne and Sydney, Australia. This approach allows the strengths and roles of genetic and environmental risk factors to be studied within an epidemiological setting, and has the potential to address the consequences for public health of new molecular genetic findings.

      The sample included 17,425 three-generation families ascertained via population-based sampling of breast cancer probands from two studies: 2,712 families from the population-based case-control family study within the Australian Breast Cancer Family Registry (ABCFR) and 14,713 families from the prospective Studies of Epidemiology and Risk Factors in Cancer Heredity (SEARCH) study in the UK. ABCFR22–24 includes (1) 1,644 case families, ascertained independently of their family history through a sample of adult women living in the metropolitan areas of Melbourne and Sydney who were diagnosed between 1992 and 1999 (baseline) with a histologically confirmed first primary breast cancer (case probands) before age 70 years and (2) 1,068 control families ascertained through unaffected adult women (control probands) who were sampled at the same time via the Australian electoral rolls and frequency matched to case probands by age. Of these, 858 case families with a proband diagnosed with breast cancer before age 40 years were included in a previous segregation analysis.13

      The study was approved by the ethics committees of The University of Melbourne and The Cancer Council Victoria. The Australian breast cancer family registry (ABCFR) includes a population-based, case-control-family study of breast cancer (in which cases, control subjects and their relatives were administered the same questionnaire) with an emphasis on early-onset disease that was carried out in Melbourne and Sydney, Australia.10–12 Sixty-six women were identified within the ABCFR to be diagnosed with breast cancer before the age of 40 years and to have a strong family history of breast and/or ovarian cancer (two or more first- or second-degree relatives affected with breast and/or ovarian cancer).
