How I Communicate with Patients and Families about Germline Genetic Information

Abstract

Because germ line genetic testing is increasingly integrated into the clinical care of patients with hematologic malignancies, it is important for hematologists to effectively communicate with patients and their families about the genetic testing process and to relay the results in a concise and understandable manner. Effective communication facilitates trust between patients and providers and allows patients to feel empowered to ask questions and actively participate in their health care. Especially for inherited conditions, the patient's understanding of germ line genetic information is critical because it enables them to share this information with relatives who are at risk, thereby promoting cascade testing and providing potentially life-saving information to family members who may be similarly affected. Accordingly, a hematologist's skills in understanding the importance and implications of germ line genetic information and the ability to convey this information in patient-friendly language is a critical first step and can have a far-reaching impact. In this article, we outline a straightforward approach to discussing genetic information and provide the reader with practical tips that can be used when consenting patients to germ line genetic testing and disclosing subsequent test results. We also review special considerations and ethical concerns arising when offering genetic evaluation and germ line testing to patients and related donors for allogeneic hematopoietic stem cell transplantation.
