Des-gamma-carboxy prothrombin and alpha-fetoprotein levels as biomarkers for hepatocellular carcinoma and their correlation with radiological characteristics

Advances in application of serum biomarkers for screening and early diagnosis of hepatocellular carcinoma

Hepatocellular carcinoma (HCC) represents a major global health challenge, with early detection through surveillance of high-risk populations remaining critical for improving clinical outcomes. Serum biomarkers play a crucial role in the early detection of HCC. Currently, commonly used serological markers for HCC include alpha-fetoprotein (AFP), des-gamma-carboxy prothrombin, and the Lens culinaris agglutinin-reactive fraction of AFP. Other potential biomarkers under investigation include glypican-3, osteopontin, alpha-L-fucosidase, Dickkopf-1, heat shock protein 90α, and Golgi protein 73. With the advancement of liquid biopsy technologies, novel markers such as circulating tumor DNA, circulating tumor cells, microRNAs, and long non-coding RNAs have emerged as promising tools for early screening and diagnosis of HCC. This review aims to summarize the research progress and clinical applications of these biomarkers related to liver cancer, providing scientific evidence to enhance early diagnosis rates, improve prognosis, and ultimately reduce HCC-related mortality.

Beyond the Liver: A Comprehensive Review of Strategies to Prevent Hepatocellular Carcinoma

BACKGROUND/OBJECTIVES

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality worldwide, primarily developing in the context of chronic liver disease. Traditional prevention has focused on liver-specific interventions like antiviral therapies and surveillance. However, extrahepatic factors also significantly contribute to HCC risk. This review explores comprehensive strategies for HCC prevention, including both hepatic and extrahepatic factors.

METHODS

An extensive literature search of peer-reviewed articles up to October 2024 was conducted, focusing on studies addressing HCC prevention strategies. Studies that focused on both hepatic and extrahepatic factors were included. Data were extracted and synthesized to provide an overview of current prevention strategies and their effectiveness in reducing HCC incidence.

RESULTS

Hepatitis B vaccination and antiviral treatments for hepatitis B and C significantly reduce HCC incidence. Lifestyle modifications-such as reducing alcohol consumption, maintaining a healthy weight through diet and exercise, and smoking cessation-are crucial in lowering HCC risk. Environmental measures to limit exposure to aflatoxins and other hazards also contribute to prevention. Regular surveillance of high-risk groups enables early detection and improves survival rates. Emerging strategies like immunotherapy and gene therapy show potential for further reducing HCC risk.

CONCLUSIONS

A comprehensive approach combining medical interventions, lifestyle changes, and environmental controls is essential for effectively decreasing HCC incidence globally. Implementing these combined measures could significantly reduce the global burden of HCC.

Biomarker discovery in hepatocellular carcinoma (HCC) for personalized treatment and enhanced prognosis

Hepatocellular carcinoma (HCC) is a leading contributor to cancer-related deaths worldwide and presents significant challenges in diagnosis and treatment due to its heterogeneous nature. The discovery of biomarkers has become crucial in addressing these challenges, promising early detection, precise diagnosis, and personalized treatment plans. Key biomarkers, such as alpha fetoprotein (AFP) glypican 3 (GPC3) and des gamma carboxy prothrombin (DCP) have shown potential in improving clinical results. Progress in proteomic technologies, including next-generation sequencing (NGS), mass spectrometry, and liquid biopsies detecting circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA), has deepened our understanding of HCC's molecular landscape. Immunological markers, like PD-L1 expression and tumor-infiltrating lymphocytes (TILs), also play a crucial role in guiding immunotherapy decisions. Despite these advancements, challenges remain in biomarker validation, standardization, integration into clinical practice, and cost-related barriers. Emerging technologies like single-cell sequencing and machine learning offer promising avenues for further exploration. Continued investment in research and collaboration among researchers, healthcare providers, and policymakers is vital to harness the potential of biomarkers fully, ultimately revolutionizing HCC management and improving patient outcomes through personalized treatment approaches.
