  Purpose

One in 10 Canadian women will be diagnosed with breast cancer (BC) and approximately 5% of all BC is believed to be hereditary. Women with a family history experience high levels of perceived risk for developing BC. Elevated risk perceptions for BC have been associated with psychological distress, which, in turn, can interfere with screening adherence. In our completed CBCRI-funded study, we developed and standardized a group intervention designed to address the psychological issues associated with having a family history of BC. Results demonstrated that the intervention led to significant improvement in levels of anxiety and depression, improved BC risk factors/genetics knowledge and was associated with optimal screening behavior. The proposed study will rigorously test the group intervention in comparison to standard risk counselling in a sample of 150 women recruited from Familial BC clinics in Toronto. The interventions will be examined for their impact on a) psychological functioning, b) BC risk/genetic knowledge and c) screening behaviors.

Keywords: Breast cancer, genetics, psychotherapy, group counselling, randomized control trial, risk counselling, women's mental health, familial breast cancer.

One in 10 Canadian women will be diagnosed with breast cancer (BC) and approximately 5% of all BC is believed to be hereditary. Women with a family history of BC experience high levels of perceived risk and vulnerability for developing BC. Elevated risk perceptions for BC are difficult to modify and have been associated with psychological distress that, in turn, can interfere with screening adherence. The specific objectives of the current randomized trial are to determine the effects of a supportive-expressive group intervention on a) psychosocial functioning (using standardized instruments), b) BC risk/genetic knowledge and c) screening behaviors in women with a family history of breast cancer receiving standard genetic risk counseling. Preliminary data will be collected to examine the cost effectiveness of the intervention.

The study is being conducted in the following University of Toronto affiliated teaching hospitals: Mount Sinai Hospital; Preventive Oncology Program, Sunnybrook and Women's College Health Sciences; Toronto Sunnybrook Regional Cancer Centre; University Health Network; North York General Hospital; Credit Valley Hospital. A total of 150 women with a family history of BC will be randomized in a ratio of 2 to 1 to participate in an 8 weekly/ 4 monthly support group or to a control arm that receives educational materials.

The study has been funded by the Canadian Breast Cancer Research Initiative (CBCRI) of the National Cancer Institute of Canada since 2001. To date 66 women have been enrolled in the study and we anticipate a total of 90 women will be enrolled by the end of the current funding year in June 2004. At this rate it is expected that recruitment will be completed in June 2005, the last intervention groups will be completed by January 2006 and that analysis of the final study results will be completed by June 2006. Analysis of baseline data will begin in September 2005 once the last study groups have been initiated and a manuscript reporting the final results will be prepared by June 2006. Two years of funding is requested for these activities.

Significance: Technological advances in molecular biology and genetics are occurring rapidly. Our proposed research has direct relevance for advancing knowledge on the communication and provision of risk/genetic information to individuals with a family history of BC and has both direct and indirect relevance to individuals at all stages of cancer. Improved counselling techniques for those with a family history may impact on the prevention and management of BC through improved surveillance and preventive techniques, enhanced psychosocial functioning and wellbeing through increased psychological resilience. In addition, effective risk counselling interventions may facilitate the understanding of and decision-making around genetic testing, and the adjustment to a cancer diagnosis, should these women with family histories later develop the disease.
