Background
Molecular testing to inform treatment and clinical trial choices is now standard of care in several types of cancer. However, no established guidelines exist for the type of information physicians should cover during discussions with the patient about the test or its results. The objectives of this study were to identify physician and patient information preferences, as well as their preferences on who should communicate this information and how, to inform guidelines for these conversations.
Methods
Physicians and patients that participate in discussions regarding molecular testing were asked to choose 8 topics of most relevance out of a list of 18. McNemar's test was used to determine their top preferences. Patients were asked who/what should inform them and physicians were asked to identify the best aid to communication.
Results
Sixty-six patients identified 12 preferred topics: benefits of testing(88%); how testing determines treatment(88%); implications for family(71%), if test shows seriousness of disease(68%), purpose(64%), incidental findings(56%); explanation of cancer genetics(53%), how the test is done(46%), limitations(44%), explanation of biomarker(42%), risks(42%), and uninformative result(38%). Physicians added cost(59%). Patients preferred receiving information about molecular testing from their nurse or physician(85%) and physicians preferred using a pamphlet(67%) to augment communication.
Conclusion
The topics identified as important to discuss can inform future guidelines as well as contribute to effective communication regarding molecular testing.
