In addition, the level of ctDNA as a percent of total cell-free DNA will be summarized by reporting the median and range. Since no prior data are available on the rate of positivity nor the change over time, the analysis will be purely descriptive. Changes over time will be plotted to visually determine and compare the trajectories of ctDNA during the early and late stages of therapy.","reportingStatus":"NOT_POSTED","timeFrame":"Up to 10 years","title":"Frequency of Circulating Tumor DNA (ctDNA) at Diagnosis and Subsequent Time-points","type":"OTHER_PRE_SPECIFIED"}
