Ultra-deep sequencing of plasma DNA identifies druggable mutations in hepatocellular carcinoma


ABSTRACT: The purpose of the study is to detect somatic mutations in hepatocellular carcinoma using circulating free-DNA. We used deep-sequencing data of a panel of 60 commonly mutated genes in hepatocellular carcinoma.

Cellular components of solid tumors including DNA are released into the bloodstream, but data on circulating-free DNA (cfDNA) in hepatocellular carcinoma (HCC) are still scarce. This study aimed at analyzing mutations in cfDNA and their correlation with tissue mutations in patients with HCC. We included 8 HCC patients treated with surgical resection for whom we collected paired tissue and plasma/serum samples. We analyzed 45 specimens, including multiregional tumor tissue sampling (n = 24), peri  ...[more]
