Abstract

Personalized medicine has gained increasing importance in clinical oncology, and several clinically important biomarkers are implemented in routine practice. In an effort to guarantee high quality of molecular testing in France, three subsequent external quality assessment rounds were organized at the initiative of the National Cancer Institute between 2012 and 2014. The schemes included clinically relevant biomarkers for metastatic colorectal (KRAS, NRAS, BRAF, PIK3CA, microsatellite instability) and non-small cell lung cancer (EGFR, KRAS, BRAF, PIK3CA, ERBB2), and they represent the first multigene/multicancer studies throughout Europe. In total, 56 laboratories coordinated by 28 regional molecular centers participated in the schemes. Laboratories received formalin-fixed, paraffin-embedded samples and were asked to use routine methods for molecular testing to predict patient response to targeted therapies. They were encouraged to return results within 14 calendar days after sample receipt. Both genotyping and reporting were evaluated separately. During the three external quality assessment rounds, mean genotype scores were all above the preset standard of 90% for all biomarkers. Participants were mainly challenged in case of rare insertions or deletions. Assessment of the written reports showed substantial progress between the external quality assessment schemes on multiple criteria. Several essential elements such as the clinical interpretation of test results and the reason for testing still require improvement by continued external quality assessment education.
