Abstract:

Molecular testing is increasingly being integrated into cancer management. Despite rapid advancements, little work has been done to explore strategies for communicating with patients undergoing molecular tumor testing. This study evaluated the impact of genetic counseling educational tools on improving patients’ understanding of key terms related to molecular testing. A genetic counseling intern designed a picture book to explain six words found in prior research to be difficult to understand (mutation, germline mutation, somatic mutation, biomarker, molecular testing, and targeted therapy). Participants who had previously discussed molecular testing with their oncologist were asked to define the terms. The same participants then received an explanation of each term either from the intern using the picture book in person or from a video presentation of the picture book. They were then asked to redefine each term afterward. The difference between the number of terms defined correctly pre- and post-intervention was compared between presentations. Sixty-three patients with melanoma, colon, lung, or breast cancer were recruited. After both interventions, correct understanding rates improved for all six terms, with significant improvement for germline mutation (p < 0.001), somatic mutation (p < 0.001), biomarker (p < 0.001), and molecular testing (p < 0.001). Understanding of targeted therapy improved significantly (p = 0.011) for the video presentation only. Mean change in knowledge scores did not differ between the two interventions (intern presentation 3.2 vs. video 2.9, p = 0.428). Our data suggest that genetic counseling educational tools can increase patient understanding of terms used to describe molecular testing.
