Figure 4.
Concordance between GAs found in ctDNA and matched tissue from 25 patients with gastrointestinal carcinomas. A, Days between ctDNA and tissue collection, MSAF, and disease histology are shown. CR, colorectal adenocarcinoma; G, gastric adenocarcinoma; RE, rearrangement. Concordant/shared GAs are in blue, GAs found only in tissue are in red, and GAs found only in ctDNA are in pink. For samples with multiple unique mutations in a given gene, the number of mutations is indicated. B, Venn diagrams of concordant and discordant alterations by class. Blue, GAs found in both ctDNA and tissue; pink, GAs found only in ctDNA; red, GAs found only in tissue.
