Abstract excerpt
Detection of somatic mutations in cell-free DNA (cfDNA) is challenging due to low variant allele frequencies and extensive DNA degradation. Here we develop a benchmarking strategy using longitudinal patient-matched cfDNA samples from individuals with colorectal and breast cancer. Samples with high and ultra-low levels of tumor-derived DNA are combined into controlled dilution series that preserve the properties...
