Area of Science:

  • Hepatology and Oncology
  • Diagnostic Imaging
  • Interventional Radiology

Background:

  • Hepatocellular carcinoma (HCC) is a significant global health concern, particularly among patients with underlying liver disease like cirrhosis.
  • Accurate risk stratification and early detection are crucial for improving patient outcomes.

Purpose of the Study:

  • To review current knowledge on risk factors, early detection markers, diagnostic approaches, and therapeutic strategies for hepatocellular carcinoma.
  • To highlight advancements in surveillance, imaging, and ablation techniques for HCC management.

Main Methods:

  • Systematic review of recent literature on hepatocellular carcinoma.
  • Analysis of data from randomized controlled trials (RCTs) and observational studies.
  • Evaluation of diagnostic criteria and staging systems for HCC.

Main Results:

  • Combined risk factors (alcohol, tobacco, obesity) identify high-risk groups within the cirrhotic population.
  • Surveillance for HCC in high-risk patients demonstrated improved survival.
  • Contrast washout in arterially enhancing lesions is a sensitive and specific marker for HCC.
  • The Barcelona Clinic Liver Cancer (BCLC) staging system effectively stratifies prognosis and guides treatment.
  • Radiofrequency ablation (RFA) offers improved survival over percutaneous ethanol injection (PEI) for early-stage HCC.

Conclusions:

  • Risk stratification is essential for tailoring HCC surveillance to high-risk cirrhotic patients.
  • Typical HCC imaging findings include contrast washout on triple-phase scans.
  • Radiofrequency ablation is the preferred ablative method for small hepatocellular carcinoma.
