Over the past 20 years, studies have highlighted the possible roles of stressful life events and distress, possibly mediated by social support and personality, in causing or speeding up the development of breast cancer. This possibility is of strong concern to consumers. To date, there have been few well designed, prospective studies of this issue.

This possibility is of strong concern to consumers. To date, there have been few well designed, prospective studies of this issue. Furthermore, no previous studies have specifically targeted women at increased risk because of their family history. In recent years, it has become possible to identify 2 breast cancer genes (BRCA1 and BRCA2). Female carriers of mutations in these genes with a strong family history have an estimated lifetime risk of between 35% and 85%. The Kathleen Cuningham Consortium for Research into Familial Breast Cancer (kConFab) was established 11 years ago to coordinate the collection of genetic, epidemiological and clinical data in Australian and New Zealand families with a dominantly inherited predisposition to breast cancer. Due to the high rate of breast cancer diagnoses in this group, and the systematic recruitment of large numbers of high risk women by kConFab, there is a unique and temporary opportunity to conduct a rigorous study to resolve this question, with sufficient numbers involved. The study is a world first, and will provide the best data to date in this area. If the study demonstrates a relationship between psychosocial factors and the development of breast cancer in women from high risk breast cancer families, subsequent identification of vulnerable individuals and the implementation of appropriate interventions may have a real impact on reducing morbidity and mortality in this population. Furthermore, the results may have implications for all women in reducing breast cancer incidence.Read moreRead less

To date there has been little prospective assessment of psychosocial factors in the development of breast cancer. Furthermore, no research in this area has specifically targeted women at increased risk because of their family history, nor explored whether the impact of psychosocial factors systematically varies according to genetic mutation status. Over the past 5 years it has become possible to isolate two breast cancer genes (BRCA1 and BRCA2). Female carriers of mutations in these susceptibility genes have an estimated lifetime risk of breast cancer of between 37% and 85%. The Kathleen Cuningham Consortium for Research into Familial Breast Cancer (KConFab) was established four years ago to co-ordinate the collection of genetic, epidemiological and clinical data in Australian families with a dominantly inherited predisposition to breast cancer. The systematic recruitment of large numbers of high risk women by KConFab provides a unique and temporary opportunity to address questions concerning psychosocial predictors of disease development in a prospective design with sufficient power, due to the higher rates of breast and ovarian cancer events in this population. We will also be able to explore interactions with genetic mutation status. The study will be a world first, and provide the most rigorous data to date in this area. If this study demonstrates a relationship between psychosocial factors and the development of breast cancer in women from high risk families, subsequent identification of vulnerable individuals and the implementation of appropriate interventions may have a real impact on reducing morbidity and mortality in this population. Furthermore, the results may have implications for all women in reducing breast cancer incidence.Read moreRead less

Summary
This Australia-wide, longitudinal study will examine the psychological effects of testing for breast cancer predisposing genes in women with a strong family history of breast cancer. Mutation detection carries with it the possibility of improving survival through increased emphasis on screening and prevention, while those found to be non-carriers can return to population screening levels, alleviating both their anxiety and the costs associated with greater vigilance.

Mutation detection carries with it the possibility of improving survival through increased emphasis on screening and prevention, while those found to be non-carriers can return to population screening levels, alleviating both their anxiety and the costs associated with greater vigilance. Preventative surgery is now known to significantly reduce risk in women with a strong family history of breast cancer. Whether these potential benefits are realised in practice needs to be evaluated, as do potential psychological harms, if any. Predictive genetic testing for hereditary breast cancer has become technically possible before its impact on psychological outcomes has been evaluated. As yet there are no Australian data on the impact of predisposition testing in any potentially treatable adult onset conditions and only preliminary overseas data. Results from this study may therefore have application to other potentially treatable adult onset conditions. Changes before and after testing in psychological status will be studied (using established methodology) over a 2-year period to identify when negative outcomes are most likely to occur. In addition, this study aims to identify factors that facilitate or hinder psychological adjustment so as to inform clinical decisions about testing and to allow appropriate interventions to be devised. Assessment of individual's preferences for the amount of information they receive will allow tailoring of information to maximise the benefit of educational materials and potentially minimise distress. Factors which influence women's decisions to undertake prophylactic surgery and their satisfaction with those procedures will be assessed.Read moreRead less

Summary
Waking up during surgery (awareness under anaesthesia) is a frightening reality for some patients. Although uncommon (occurring in about 1 in 1000 operations), it remains one of the main concerns of patients before their surgery. Recent studies (including our own) have demonstrated that processed EEG monitoring using bispectral index (BIS) can markedly reduce the risk of awareness.

Although uncommon (occurring in about 1 in 1000 operations), it remains one of the main concerns of patients before their surgery. Recent studies (including our own) have demonstrated that processed EEG monitoring using bispectral index (BIS) can markedly reduce the risk of awareness. Other EEG monitors are being developed, but each have weaknesses. As approximately two million Australians have a general anaesthetic each year, about 2000 will suffer an episode of awareness. More than 60 million people around the world have an anaesthetic, and so the problem is substantial. This suggests the potential benefits (health outcomes, commercial gains) are very great. In 2000 less than 5% of US hospitals used BIS monitoring; the current figure in the US is about 69% of the best-rated hospitals (US News and World Report) and 78% of teaching hospitals. A similar rapid growth is occurring in Australia and Europe. We are working with a successful Australian Company (Compumedics Ltd) to develop a better awareness monitor. We plan studies in groups of patients have surgery.Read moreRead less
Obstructive sleep apnea (OSA) is one of the most common complications of obesity and is independently associated with a reduced quality of life and cardiovascular disease. This project aims to identify the underlying factors linking obesity with OSA by examining how weight loss surgery can improve these factors. These important findings will contribute greatly to our understanding of OSA pathophysiology and are necessary to find better treatments for obesity-associated OSA.
