Liquid Biopsy for Hepatocellular Carcinoma Molecular Characterization After Y90

The purpose of this study is to determine if baseline liquid biopsy assays (CTC and cf-DNA) as well as single circulating tumor cell-DNA (sCTC DNA) dynamics in the early post-treatment period can predict subsequent treatment response to Y-90 radioembolization in patients with hepatocellular carcinoma (HCC).

About this study

Study Aims and Objectives:

  • Assess the detection rate of CTC and cfDNA-based mutations and the distribution of molecular features of HCC prior to Y90 across BCLC A-C stages.
  • Determine CTC and cfDNA predictors at baseline that predict Y90 treatment response at 6-9 months.
  • Determine temporal changes in CTC and cfDNA mutations from baseline over 6-9 month course post Y90.
  • Determine if CTC mean distribution, sCTCDNA, and/or cfDNA mutational dynamic changes are predictive of treatment response at 6-9 months.
  • Assess radiomic and liquid biopsy signatures associated with outcome
  • Compare predictive outcome models using liquid biopsy data, imaging data, or a combination (multiomic data)
