Abstract 315P
Background
Genetic testing (GT) is vital in the risk assessment of breast cancer (BC) and along with genetic counselling (GC), may inform treatment decisions. However, fewer than one-third of patients (pts) with BC undergo GT. A multinational survey was conducted for a deeper understanding of the barriers in the uptake of GT and GC. Results from this survey, focusing on awareness and pts’ perceptions towards GT and GC have been reported here.
Methods
A steering committee comprising of pts and pt advocates co-developed a 38-question online survey, which was launched in local languages for pts in Argentina, Australia, Brazil, Egypt, India, Malaysia, Mexico, Russia and Taiwan, through different social media platforms. The questions pathway was determined based on response to certain questions on GT & GC uptake. Percentage responses to a response option was calculated against the number of respondents for that question.
Results
The final analysis set (FAS) included responses from 1176 participants with more than 90% completion rate of survey questions. Median age among respondents in the FAS was 42 years (IQR: 35, 49) at the time of BC diagnosis. Among survey respondents, 63% (737/1176) had undergone GT, and 37% (439/1176) did not undergo GT. The table lists select questions on some aspects of the GT experience as well as perceptions of testing. Table: 315P
Question | Response | No. of respondents/Total no. of respondents to the question (%) | ||
How would you rate the awareness levels of GT/GC of yourself, before diagnosis? | Moderate to very low | 758/1061 (71) | ||
Should all pts diagnosed with BC undergo GT first before starting treatment? | Yes | Underwent GT | 603/849 (71) | 460/625 (74) |
Did not undergo GT | 143/224 (64) | |||
How willing would you be to have your children and other family members undergo GT? | Very willing | Underwent GT | 371/1176 (32) | 322/737 (44) |
Did not undergo GT | 49/439 (11) | |||
What was your main reason for not undergoing GT? | I was not offered GT | 282/394 (72) | ||
What are the main barriers to GT for you and your family? (Top 2) | Cost | 210/425 (49) | ||
Lack of understanding | 163/425 (38) |
Conclusions
There are critical gaps in the awareness of GT among pts and the public, along with gaps in perceived value and access to GT, with notable variance between the tested and the non-tested populations. Strategic action is needed to overcome the barriers to GT and to improve the pt experience.
