Hepatocellular carcinoma (HCC) screening aims for early diagnosis in high-risk patients, enabling curative treatments. However, evidence proving HCC screening reduces mortality remains inconclusive.

Area of Science:

  • Oncology
  • Hepatology
  • Medical Screening

Background:

  • Hepatocellular carcinoma (HCC) is a globally prevalent cancer, predominantly affecting individuals with chronic viral hepatitis or liver cirrhosis.
  • Early diagnosis of HCC allows for curative treatments like resection, transplantation, and ablation, potentially achieving over 60% 5-year survival rates.
  • Currently, a minority of HCC patients are diagnosed early; most present with advanced disease.

Purpose of the Study:

  • To evaluate the effectiveness of Hepatocellular carcinoma (HCC) screening programs in facilitating early diagnosis and curative treatment.
  • To assess whether current HCC screening practices demonstrably reduce overall mortality rates.

Main Methods:

  • Review of existing data on HCC screening practices, primarily focusing on high-risk populations.

Related Experiment Videos

  • Analysis of the impact of screening on the proportion of patients diagnosed at an early, curable stage.
  • Examination of evidence linking HCC screening to a reduction in HCC-specific mortality.

    • Main Results:

    • HCC screening identifies a higher proportion of patients at an early stage, increasing the likelihood of curative treatment.
    • Despite improved early diagnosis rates, conclusive evidence demonstrating that HCC screening lowers overall mortality is currently lacking.
    • Twice-yearly ultrasound and alpha-fetoprotein (AFP) testing are common screening methods for high-risk individuals globally.

    Conclusions:

    • While HCC screening facilitates early detection and increases the rate of curative interventions, its definitive benefit in reducing mortality requires further robust evidence.
    • The established practice of screening high-risk individuals for HCC continues, despite the ongoing debate regarding its impact on mortality outcomes.
