Awareness of genomic testing among patients with breast cancer in Europe

Purpose

Genomic testing, involving expression profiling of tumour tissue, is a powerful tool for determining appropriate treatments for certain cancer patients. This study aimed to evaluate awareness of genomic testing in breast cancer patients in five European countries.

Methods

The survey was initiated by Cancer Patients Europe and developed with patient associations, oncologists, and a psycho-oncologist. Participants were recruited via email and social media and completed a 42-question internet survey.

Results

Of 1383 participants in eligible countries completing the survey, 566 women with current or previous HR+/HER2- breast cancer, potentially eligible for genomic testing, were analysed. 245 (43.3 %) were aged 50–59 years and 381 (67.3 %) had received higher education. 238 participants (42.1 %) had heard about genomic testing; 122 (21.6 %) were informed of their eligibility for testing, and 104 (18.4 %) were given reasons for the test. The majority (N = 479; 84.6 %) felt they lacked sufficient information to decide, and only 139 (24.6 %) opted for testing. Overall, 246 (43.5 %) wanted more information on additional testing and 234 (41.3 %) wanted more information on treatment options. The main information sources were medical professionals (N = 363; 64.1 %) and the internet (N = 351; 62.0 %). However, 398 participants (70.3 %) indicated that their healthcare professionals did not advise them on where to find more information.

Conclusions

This study highlights insufficient awareness of, and access to, genomic testing in breast cancer. Healthcare professionals need to improve communication with patients regarding genomic testing and involve them in shared decision-making. Likewise, patient associations have a role in providing clear information to patients.
