Breast cancer specialists’ experiences and attitudes towards mainstream genetic testing for patients with breast cancer

Abstract

Germline genetic testing is an increasingly important component of treatment decision-making for clinicians and patients with breast cancer. To address increased demand and expedite access to genetic testing for these patients, the Parkville Familial Cancer Centre (PFCC) in Victoria, Australia, implemented a breast mainstream genetic testing program. The program educates and supports breast cancer specialists to provide eligible patients with pre-test information, gain consent, and arrange genetic testing during their routine cancer appointments.

This study aimed to explore breast cancer specialists’ experiences and opinions of the education program and of facilitating mainstream genetic testing for their patients. Specialists who had attended the mainstream genetic testing education were invited to complete an online survey about the training provided through the education program and their experience of deploying mainstream genetic testing in their practice. Descriptive statistics were compiled, and content analysis used for open text responses.

Forty-five breast cancer specialists (breast surgeons, medical oncologists, radiation oncologists and breast care nurses) responded (45% response rate). Most participants had discussed (87%) and consented (80%) patients for mainstream genetic testing. Most specialists (81%) rated their confidence levels as high or very high for consenting patients to mainstream genetic testing. The majority (89%) indicated that they believed mainstream genetic testing should be part of their role and felt well supported by the PFCC (90%).

This research demonstrates that the breast cancer specialists were satisfied by the education they received and the PFCC has successfully integrated mainstream genetic testing for breast cancer patients.
