Assessing patient readiness for personalized genomic medicine

The Human Genome Project and the continuing advances in DNA sequencing technology have ushered in a new era in genomic medicine. Successful translation of genomic medicine into clinical care will require that providers of this information are aware of the level of understanding, attitudes, perceived risks, benefits, and concerns of their patients. We used a mixed methods approach to conduct in-depth interviews with participants in the NCI-funded Breast Cancer Family Registry (BCFR). Our goal was to gain a better understanding of attitudes towards different types and amounts of genomic information, current interest in pursuing genomic testing, and perceived risks and benefits. We interviewed 32 women from the six BCFR sites in the USA, Canada, and Australia. In this sample of women with a personal or family history of breast cancer, we found high acknowledgement of the potential of genetics/genomics to improve their own health and that of their family members through lifestyle changes or alterations in their medical management. Respondents were more familiar with cancer genetics than the genetics of other diseases. Concerns about the testing itself included a potential sense of loss of control over health, feelings of guilt on passing on a mutation to a child, loss of privacy and confidentiality, questions about the test accuracy, and the potential uncertainty of the significance of test results. These data provide important insights into attitudes about the introduction of increasingly complex genetic testing, to inform interventions to prepare individuals for the introduction of this new technology into their clinical care.

Incorporate gene signature profiling into routine molecular testing

The success of gene and gene expression profiling, such as the Oncotype DX® test for breast cancer patients, demonstrates that as technology becomes more sophisticated molecular diagnostics will continue to play a more important role in disease management in the future. Such promises have been and continue to be enabled by advances in real-time PCR, microarray detection platforms and next generation sequencing technologies. Practical adoption of new technologies into routine clinical care, however, has not always been a smooth ride. Challenges lie on several fronts: establishment of clinical validity in large scale patient population, mechanisms of incorporating molecular tests into standard care, and keeping up with the pace of ever changing technologies in regulated clinical laboratories, just to name a few. This review's goals are to educate, to stimulate discussion and to provoke efforts to build consensus, share resources, and establish standards in order to realize the promises of genomic technologies for routine patient care.
