The clinical role of 'liquid biopsy' in hepatocellular carcinoma.
Circulating free tumor DNA (ctDNA) is DNA released from necrotic or apoptotic tumor cells into the bloodstream. Absolute levels of ctDNA, as well as genetic mutations and epigenetic changes detected in ctDNA are useful biomarkers of tumor biology, progression and response to therapy in many tumor types and recent evidence suggests they may be useful in hepatocellular carcinoma (HCC). ctDNA detected in blood, therefore, offers a minimally invasive, easily repeated 'liquid biopsy' of cancer, providing real-time dynamic analysis of tumor behavior and treatment response that could revolutionize both clinical and research practice in HCC. In this review, we provide a critical summary of the evidence for the utility of ctDNA as a diagnostic and prognostic biomarker in HCC.
期刊介绍:
Primary liver cancer is the sixth most common cancer in the world, and the third most common cause of death from malignant disease. Traditionally more common in developing countries, hepatocellular carcinoma is becoming increasingly prevalent in the Western world, primarily due to an increase in hepatitis C virus infection. Emerging risk factors, such as non-alcoholic fatty liver disease and obesity are also of concern for the future. In addition, metastatic tumors of the liver are more common than primary disease. Some studies report hepatic metastases in as many as 40 to 50% of adult patients with extrahepatic primary tumors. Hepatic Oncology publishes original research studies and reviews addressing preventive, diagnostic and therapeutic approaches to all types of cancer of the liver, in both the adult and pediatric populations. The journal also highlights significant advances in basic and translational research, and places them in context for future therapy. Hepatic Oncology provides a forum to report and debate all aspects of cancer of the liver and bile ducts. The journal publishes original research studies, full reviews and commentaries, with all articles subject to independent review by a minimum of three independent experts. Unsolicited article proposals are welcomed and authors are required to comply fully with the journal''s Disclosure & Conflict of Interest Policy as well as major publishing guidelines, including ICMJE and GPP3.
