Cellular prognostic markers in hepatocellular carcinoma

Area of Science:

• Oncology
• Immunology
• Hepatology

Background:

• Hepatocellular carcinoma (HCC) is a leading cause of cancer death globally.
• HCC is strongly associated with chronic hepatitis B (HBV) and hepatitis C (HCV) infections.
• The tumor microenvironment significantly impacts HCC progression, invasion, angiogenesis, and metastasis.

Purpose of the Study:

• To review the current state of research on tumor-infiltrating cells in HCC.
• To highlight the correlation between specific immune cells and HCC clinical prognosis.
• To identify potential biomarkers for HCC diagnosis and prognosis from the tumor microenvironment.

Main Methods:

• Systematic literature review of studies investigating the tumor microenvironment in HCC.
• Analysis of research correlating intratumoral cell infiltration with HCC progression and patient outcomes.
• Evaluation of the diagnostic and prognostic potential of identified cells.

Main Results:

• Numerous studies demonstrate a strong link between intratumoral cell infiltration and HCC clinical prognosis.
• Specific immune cells within the tumor microenvironment influence tumor growth, invasion, angiogenesis, and metastasis.
• Currently, no single cell type within the HCC microenvironment is validated for routine clinical use.

Conclusions:

• The tumor microenvironment, particularly infiltrating cells, is crucial for understanding HCC progression.
• Further research is needed to validate specific cellular biomarkers for HCC diagnosis and prognosis.
• Targeting tumor-infiltrating cells may offer future therapeutic strategies for HCC.
