Consent model for tumour genetic testing in ovarian cancer

Prospective parallel genetic testing of both germline and tumour DNA in ovarian cancer patients (OC) is the recommended model in several different countries across the globe and the UK. The high (∼67%) chance of identifying germline PVs in patients with tumour PVs has led to a discourse surrounding the need for consent for tumour genetic testing in OC. We discussed with OC patients during focus group workshops, physicians, and charity representatives about consent options for tumour testing in OC patients: verbal consent prior to testing (Option 1) and reflex testing (Option 2). Most patients (97%; 33/34) did not feel that consent was required and were happy with reflex testing (Option 2). Physician consensus was that reflex testing was preferred and most charity representatives (4/5; 80%) agreed. All groups wanted an opt-out option and a patient information sheet about tumour testing. This can inform new recommendations in the UK and foster further discussions regarding consent for OC tumour testing.
