Background Variability of ctDNA Levels in Plasma of Patients with Advanced Lung Cancer in the Absence of Treatment

Time: 11:00 am
day: Day Two


  • Quantifying changes in circulating tumor DNA (ctDNA) can rapidly identify patients responding to therapy
  • Accurate quantification of ctDNA levels is required and it’s important to understand biological and technical variabilities in ctDNA measurements
  • The results of our analysis of technical and biological variability of ctDNA levels in pre-treatment samples from patients with advanced EGFRm NSCLC, highlighting the importance of biological variability and the stringent molecular response definition
