Circulating tumor DNA (ctDNA) has emerged as a promising tool in the diagnosis, monitoring, and management of hepatocellular carcinoma (HCC). This non-invasive "liquid biopsy" technique offers several advantages in understanding and treating HCC.
In a study of 58 Chinese advanced HCC patients, ctDNA was detected in 89.7% of cases, demonstrating its high sensitivity.
The most frequently mutated genes identified in HCC through ctDNA analysis are:
In a study of HCC patients treated with neoadjuvant cemiplimab (an anti-PD-1 therapy), ctDNA changes correlated closely with tumor necrosis and relapse-free survival (RFS)
