Information Sources Used by Oncologists to Understand Multi-marker Tumor Panel Tests for Cancer Patients

Precision medicine using multi-marker tumor panel (MMTP) testing can help inform cancer treatment decisions. Oncologists’ knowledge of these tests and their ability to find up-to-date information about their application in clinical care is essential. This study aimed to (1) describe information sources used by oncologists to learn about new genomic tests and (2) examine characteristics associated with the use of each information source. The National Cancer Institute’s National Survey of Precision Medicine in Cancer Treatment surveyed a nationally representative sample of oncologists about MMTP testing. We examined the use of 11 information sources among oncologists that reported using MMTP tests ( n = 1222). Bivariate analyses were used to examine whether information sources differed by oncologist- and practice-level characteristics and type of MMTP test. Most oncologists reported using peer-reviewed medical literature (88.8%), scientific conferences (87.9%), and medical professional societies (83.8%) to learn about MMTPs. In contrast, government websites, FDA inserts, and foundation resources were each used by
