Extended Data Fig. 5

a, Comparative molecular profiling of pathogenic mutations and CNVs in paired tissue at baseline and plasma at relapse samples from 25 CC patients. Each box in the illustration denotes a mutated gene in an individual patient, bifurcated into two sections by a line. The left segment corresponds to findings derived from the primary tumor, while the right segment corresponds to plasma at relapse. Similarly, each box associated with a specific collection moment is further divided into two components: the left portion denotes point mutations, and the right portion represents CNVs. The Y-axis is organized based on the number of point mutations for each gene across all patients. b, Concordance comparison between the primary tumor and plasma at relapse (n = 25 patients) versus the concordance of plasma at both baseline and relapse (n = 12 patients) of somatic mutations across the discovery cohort (two-sided Wilcoxon test; p-value = 0.0015). Data are presented as median values +/- standard deviation. Concordance is calculated by comparing each patient with themselves at different stages.
