Patient experiences of cancer genetic testing by non-genetics providers in the surgical setting

As indications for hereditary cancer genetic testing (GT) for patients with breast cancer (BC) expand, breast surgery teams offer GT to newly diagnosed patients to inform surgical plans. There is, however, limited data on the experiences of patients undergoing cancer GT by non-genetic providers. This study used in-depth interviews with 21 women recently diagnosed with BC at a large academic health system to capture their experiences. Post-positivist codebook thematic analysis was used to identify major themes from the interviews. Participants reported an overall positive experience of this GT process, stating that they prefer GT at an existing appointment shortly after their diagnosis, even though they described the conversation as brief. Many participants indicated thinking about or desiring GT before the offer was made. Interestingly, most participants did not see surgical decision-making as the main reason for GT and were instead motivated by concern for relatives and to have complete information. Interview data indicated areas for improvement in patient-provider communication, and most participants agreed that additional reference information on GT in the form of written or video materials would be helpful. Offering GT at an initial breast surgery appointment is acceptable and desired by patients with a new BC diagnosis and should be considered as a way to increase access to GT for these patients. However, additional information for patients is needed to close gaps in communication and provide a trustworthy reference following a busy medical appointment.
