Hepatocellular Carcinoma cfDNA (MSK, JCO Precision Oncology 2023)
Overview
Single-center cohort of 51 patients with histologically confirmed advanced hepatocellular carcinoma (HCC) at Memorial Sloan Kettering Cancer Center (February 2019 – August 2021), profiling circulating cell-free DNA (cfDNA) using MSK-ACCESS. Matched tumor tissue MSK-IMPACT data available for 37 patients (72.5%). Data deposited in cBioPortal as hcc_jcopo_msk_2023. PMID:37769223
Composition
- 53 plasma samples from 51 patients with inoperable advanced HCC; AJCC stage IV (74%), III (18%), II (8%). PMID:37769223
- Median age 69 years; 76% male; 47% hepatitis B/C etiology, 53% non-viral. PMID:37769223
- 47% treatment-naive at cfDNA collection; 35% prior TKI; 18% prior anti-PD-1/PD-L1. PMID:37769223
Assays / panels (linked)
- MSK-ACCESS 129-gene plasma panel (~200,000x raw coverage with error suppression). PMID:37769223
- MSK-IMPACT for matched tumor tissue in 37 patients. PMID:37769223

Notable findings derived from this cohort
- Genomic alterations detected in 90.6% of plasma samples. Median cfDNA yield 39.43 ng; median VAF 0.027. PMID:37769223
- Top cfDNA mutation frequencies: TERT promoter 57%, TP53 47%, CTNNB1 37%, ARID1A 18%, TSC2 14%. PMID:37769223
- cfDNA detected 92.5% of alterations previously called in matched tumor tissue; cfDNA-exclusive alterations found in 27% of paired samples, 40% of which were OncoKB level 3b actionable. PMID:37769223
- TP53 significantly more prevalent in cfDNA vs. published tissue cohort (51% vs. 32%, P=0.024). PMID:37769223
