Abstract
This paper explores patients' views and experiences of undergoing treatment-focused BRCA1 and BRCA2 genetic testing (TFGT), either offered following triaging to clinical genetics (breast cancer) or as part of a mainstreamed care pathway in oncology (ovarian cancer). Drawing on 26 in-depth interviews with patients with breast or ovarian cancer who had undergone TFGT, this retrospective study examines patients' views of genetic testing at this point in their care pathway, focusing on issues, such as initial response to the offer of testing, motivations for undergoing testing, and views on care pathways. Patients were amenable to the incorporation of TFGT at an early stage in their cancer care irrespective of (any) prior anticipation of having a genetic test or family history. While patients were glad to have been offered TFGT as part of their care, some questioned the logic of the test's timing in relation to their cancer treatment. Crucially, patients appeared unable to disentangle the treatment role of TFGT from its preventative function for self and other family members, suggesting that some may undergo TFGT to obtain information for others rather than for self.Entities:

Introducing TFGT to patients

| Patients are usually triaged for TFGT during their first surgical appointment following case discussion at the weekly MDM. If considered by the team (surgeons and breast oncologists) to meet testing criteria, patients are offered a referral to clinical genetics, by their surgeon, for pre-test counseling and TFGT. The extent to which patients are informed at this stage about the possible implications of TFGT for surgery, adjuvant therapy, and the family varies. For example, it was clear from observations of MDMs and clinician interviews that while some felt comfortable to discuss various implications of TFGT prior to the test, others were more likely to take a staggered approach, that is, only discussing surgical or adjuvant implications if the patient is found to have a PV or VUS at which point the patient is also referred back to clinical genetics for further counseling and family cascading. | Patients are offered TFGT at the “new patient” clinic. The test is usually raised at the end of the consultation and is presented as a straightforward blood test that might help to explain why the individual may have developed cancer. In these appointments, there is little discussion of familial implications, or treatment implications, associated with a PV or VUS, although this varied slightly between consultants. Instead, patients are assured that if the test result comes back with a “positive” result (PV, but also including VUS) that they will be offered an appointment at clinical genetics in order to discuss familial implications with a trained genetic counselor. If the patient wishes to go ahead, a specialist nurse takes the blood following the consultation. Patients are given written information by the consultant to take away with them. |

aFor patients from families with extensive family history of different cancers, only the closest relatives have been included. For example, if someone has a grandmother with breast cancer, a grandfather with stomach cancer, and an auntie with breast cancer, they will be listed under ≥ 1 second-degree relatives (BRCA and/or OVCA)
