Background/Aim
New biomarkers are urgently needed to aid in the diagnosis of early stage hepatocellular carcinoma (HCC). We performed a meta-analysis on the diagnostic utility of circulating tumor DNA (ctDNA) levels in patients with hepatitis B virus-induced HCC.
Methods
We retrieved relevant articles from PubMed, Embase, and the Cochrane Library up to February 8, 2022. Two subgroups were defined; one subset of studies analyzed the ctDNA methylation status, and the other subset combined tumor markers and ctDNA assays. Pooled sensitivity (SEN), specificity (SPE), positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and area under the summary receiver operating characteristic curve (AUC) were analyzed.
Results
Nine articles including 2,161 participants were included. The overall SEN and SPE were 0.705 (95% confidence interval [CI], 0.629-0.771) and 0.833 (95% CI, 0.769-0.882), respectively. The DOR, PLR, and NLR were 11.759 (95% CI, 7.982-17.322), 4.285 (95% CI, 3.098- 5.925), and 0.336 (0.301-0.366), respectively. The ctDNA assay subset exhibited an AUC of 0.835. The AUC of the combined tumor marker and ctDNA assay was 0.848, with an SEN of 0.761 (95% CI, 0.659-0.839) and an SPE of 0.828 (95% CI, 0.692-0.911).
Conclusions
Circulating tumor DNA has promising diagnostic potential for HCC. It can serve as an auxiliary tool for HCC screening and detection, especially when combined with tumor markers.

Abstract PDF

Systemic target therapeutic drugs, such as sorafenib, lenvatinib, or regorafenib are the only drugs that are known to be effective against advanced hepatocellular carcinoma (HCC). However, these agents show a limited efficacy in killing residual tumors. Immunotherapy is an alternative approach to this treatment and has been used to successfully treat different cancers, including HCC. HCC is an inflammation-induced cancer and represents a very interesting target for immunotherapeutics. Immunotherapies aim to reverse the immune tolerance and suppression found in tumor microenvironments and include approaches, such as adoptive cell therapy, immune checkpoint inhibition, and cancer vaccination. Adoptive cell therapy uses autologous natural killer or cytokine-induced killer cells by cultivating them ex vivo and subsequently reinfusing them into the patient. Immune checkpoint inhibitors reactivate tumorspecific T cells by suppressing checkpoint-mediated inhibitory signaling. Cancer vaccination induces a tumor-specific immune response by activating effector T lymphocytes. A wide range of potential immunotherapy-related adverse events occur; therefore, a multidisciplinary collaborative management is required across the clinical spectrum. This review summarizes the current status of immunotherapy for HCC and provides a perspective on its future applications.

Abstract PDF: Hepatocellular carcinoma (HCC) surveillance programs have led to an increase in the adoption of radical therapies. Nevertheless, HCCs often present at an advanced stage and the prognosis remains dismal even after resection due to the high rate of recurrence. The study of tumor biology is important to predict clinical outcome enabling more appropriate therapeutic decisions for HCC patients. Understanding molecular mechanisms of hepatocarcinogenesis may also lead to effective strategies in chemoprevention. However, current staging systems based on clinicopathologic factors are limited in prognostic prediction. Recently, there has been great interest in the study of gene expression profile in relation to prognosis of HCC. Global gene expression profiling may be the most appropriate technology to unravel the pathogenesis of HCC and explore its heterogeneous origin. The elucidation of tumor biology of HCC is of paramount clinical importance in the new era of molecular target therapy.
