Hypothesis

Does a novel community-based model of breast cancer genetics services provide comparable psychological outcomes to the existing standard regional service?

Conclusion

The novel community-based model of breast cancer genetics services is generally comparable to the existing standard regional service in terms of psychological outcomes experienced by recipients.

Supporting Evidence

  • Women at moderate/high risk showed significant improvements in subjective understanding after counseling.
  • Overall, there was a significant decrease in the proportion of participants suffering from 'case-level' distress over the study period.
  • Participants reported greater subjective understanding of issues related to breast cancer risk after consulting cancer genetics services.

Takeaway

This study looked at how different ways of providing breast cancer genetic counseling affect women's feelings and understanding. Both methods helped women feel better about their cancer risk.

Methodology

A cluster randomised trial comparing a novel community-based service to a standard regional service for breast cancer genetic risk counseling.

Potential Biases

Potential bias due to differences in risk assignment methods and accuracy of family history details reported by participants.

Limitations

The study may have participation bias as women who dropped out tended to be in the novel service arm or at low risk of breast cancer.

Participant Demographics

Women referred for breast cancer genetic risk counseling, with a mean age of 37.3 years in the standard service arm and 39.1 years in the novel service arm.
