Exome sequencing of primary tumor and cell-free DNA. (A) The clinical course of case C1. Case C1 had one combined hepatocellular and cholangiocarcinoma (cHCC/CC) lesion in the right lobe that was removed by curative resection. Transcatheter arterial chemoembolization (TACE) was performed for intrahepatic recurrent lesions 2 years after the first surgery. We performed exome sequencing of cell-free DNA after the TACE and the primary tumor (red star). (B) The amount of total cell-free DNA extracted from the plasma samples serially obtained after TACE. Cell-free DNA was most abundant in plasma 2 days after TACE, and was therefore used for exome sequencing analysis. (C) Common mutations in cell-free DNA and primary tumor. Somatic mutations detected by probabilistic variant detection and low frequency variant detection are indicated by the red and pink boxes, respectively.
