Study Notes

Introduction to Hepatocellular Carcinoma (HCC)

  • HCC is the fifth most prevalent cancer globally, often linked to chronic hepatitis B infection in developing countries.
  • In the Czech Republic, HCC is rare, with around 500 cases annually, primarily affecting patients with liver cirrhosis.
  • Early detection enhances the effectiveness of treatment and patient outcomes, underlining the importance of screening initiatives.

Screening for HCC

  • Symptomatic HCC has a grim prognosis, with 5-year survival rates of 0-10%; asymptomatic cases detected through screening show over 50% survival rates.
  • A randomized trial demonstrated a 37% reduction in HCC mortality with screening using alpha-fetoprotein (AFP) and ultrasound at 6-month intervals.
  • Challenges remain in patient compliance with screening protocols, potentially understating efficacy.
  • Uncontrolled studies indicate that screening leads to earlier diagnosis and improved survival, but biases exist.

Target Groups for HCC Screening

  • Effective screening is recommended for groups with an annual HCC incidence of at least 1.5%.
  • Higher incidence rates (3-8%) occur in patients with cirrhosis from chronic hepatitis B or C infections.
  • Inclusion criteria for the Czech Republic's screening program:
    • Patients with liver cirrhosis (any cause).
    • Chronic HBV carriers (HBsAg positive).
    • Chronic HCV patients with significant fibrosis or non-alcoholic steatohepatitis.

Screening Method

  • AFP testing is no longer recommended; liver ultrasound is the preferred screening method, conducted every 6 months.
  • The exclusion of AFP is due to its low sensitivity for small HCC foci.
  • The ultrasound procedure is standardized, and no need exists to reduce the interval between screenings.

Diagnosis of HCC

  • HCC can be diagnosed using histological analysis or non-invasive imaging methods.
  • For small nodules (<2 cm) in cirrhotic patients, biopsy helps establish malignancy.
  • Distinct histopathological criteria developed through international consensus have refined HCC diagnosis, especially for early stages.

Non-Invasive Diagnostic Investigations

  • The role of AFP in diagnosis has diminished, with imaging modalities like CT or MRI now serving as primary diagnostic tools.
  • A hypervascular nodule >1 cm with typical washout patterns on imaging confirms HCC diagnosis in cirrhotic patients.
  • Non-invasive criteria are invalid for non-cirrhotic patients.

Staging of HCC

  • Unique staging systems beyond TNM classification are utilized due to the impact of liver cirrhosis.
  • The Barcelona Clinic Liver Cancer (BCLC) criteria is the leading staging system incorporating tumor extent, liver disease progression, and patient condition.
  • BCLC facilitates guided therapy and is the reference point for most treatment studies.

Surgical Treatment Options for HCC

  • Surgical options for HCC include liver resection and liver transplantation, considered potentially curative.
  • Radiofrequency ablation (RFA) is a less invasive alternative, providing curative potential.
  • Decisions regarding surgical approaches are influenced by tumor characteristics and underlying liver health.

Indication Criteria for Liver Transplantation

  • Milan Criteria define eligibility for transplantation: a single tumor ≤5 cm or up to three tumors ≤3 cm with no vascular invasion.
  • The expansion of criteria such as UCSF and "up-to-seven" aims to optimize transplant outcomes while considering tumor size and quantity.

Efficacy of RFA in HCC Treatment

  • RF ablation achieves approximately 90% complete ablation in tumors <3 cm.
  • Histological studies show completeness of necrosis influenced by tumor size and proximity to major vessels.
  • Compared to percutaneous ethanol injection (PEI), RF ablation offers superior local control and should be the preferred method in early-stage HCC.

Tumor Staging Considerations for RFA

  • The suitability of lesions for RF ablation depends on their location within the liver and the associated risks of complications.
  • Superficial lesions present higher complication risks, and lesions near major vessels can complicate treatment effectiveness.

Conclusion

  • Comprehensive understanding of HCC diagnosis, screening, treatment options, and staging is crucial for improving patient management and outcomes, particularly in regions with lower incidence rates.### Importance of Imaging Examination
  • Defining lesion locations relative to surrounding structures is crucial before treatment, particularly RF ablation, due to the risk of damaging critical anatomy.
  • Expertise of the treatment team and appropriate patient selection are essential for minimizing risks.

Examination and Follow-Up Post-Treatment

  • Standard assessment methods, CT or MRI with contrast, are performed 4-6 weeks post-treatment to evaluate patient outcomes.
  • Successful ablation sites are identified by the absence of contrast saturation or with specific saturation patterns on imaging.
  • A temporary edge of saturation indicates a normal response to thermal injury, differing from signs of residual tumor on imaging.
  • Ultrasound with intravenous contrast can be used for initial treatment assessments with follow-up CT/MRI scans at 3, 6, 9, and 12 months, then at six-month intervals for three years.
  • Local ablation is safe and effective for patients ineligible for surgical treatment for hepatocellular carcinoma (HCC), outperforming ethanol injection for lesions over 2 cm.

Transarterial Chemoembolization (TACE)

  • TACE is an effective option for treating HCC, exploiting the tumor's reliance on arterial blood supply.
  • The procedure involves occluding the artery supplying the tumor and delivering a cytostatic agent, such as cisplatin or adriamycin, often mixed with Lipiodol.
  • Contraindications for TACE include inadequate portal vein flow and advanced hepatic insufficiency (Child-Pugh B and C).
  • Sorafenib, at 800 mg/day, is recommended for advanced HCC patients unsuitable for surgical or TACE interventions.
  • Sorafenib is the first-line systemic treatment, while historical chemotherapy regimens have proven largely ineffective.

Sorafenib in HCC Treatment

  • Sorafenib serves as first-line therapy for inoperable or metastatic HCC, limited to patients with Child-Pugh class A and B liver function.
  • Use of Sorafenib is contraindicated in individuals with hypersensitivity to the drug or its components.
  • Caution advised against co-administering with acidity-reducing agents or metabolic enzyme inducers due to potential interactions.
  • Adverse effects include dermatological issues, hypertension, cardiac complications, and impaired wound healing; temporary discontinuation is suggested during major surgeries.
  • The recommended dosing is 200 mg twice daily, adjusted based on clinical benefits and side effects.

Management of Patients with Cirrhosis and HCC

  • Presence of HCC is not a primary contraindication for Transjugular Intrahepatic Portosystemic Shunt (TIPS) but requires individualized patient assessment.
  • Current recommendations on coagulation parameters pre-invasive procedures lack strong evidence, relying instead on clinical observations.
  • Prolonged coagulation management and vitamin K administration efficacy remain unclear, with no definitive guidelines established.
  • Management of ascites and liver cirrhosis complications aligns with treatments for non-HCC patients.

Summary of Treatment Process for HCC

  • Patient staging per Barcelona classification is essential for treatment strategy development.
  • Treatment options for early-stage HCC include resection, transplantation, or percutaneous ablation based on specific criteria (e.g., lesion size, number, and patient health).
  • Asymptomatic patients with multiple lesions may benefit from TACE, while ineffective TACE candidates with preserved liver function are eligible for systemic therapy.
  • Patients showing poor overall health or extensive tumor spread are best suited for symptomatic treatment rather than curative options.
  • Comprehensive staging and tailored treatment approaches are vital for optimizing outcomes in HCC patients.

Introduction

  • Hepatocellular carcinoma (HCC) is the fifth most prevalent cancer worldwide.
  • High prevalence of chronic hepatitis B infection contributes to HCC in developing nations.
  • In the Czech Republic, HCC occurs infrequently, affecting around 500 individuals annually, primarily those with liver cirrhosis.
  • Early detection is crucial for improving interventions and patient outcomes.
  • Despite lower incidence, HCC remains a public health concern due to potential benefits from screening and early treatment.

Screening

  • AFP testing is excluded from HCC screening; liver ultrasound is the sole recommended method.
  • Low efficacy of AFP testing for detecting small HCC foci prompted this recommendation.
  • The standard interval for screening with ultrasound is 6 months.
  • Procedures for detecting lesions during ultrasound are outlined visually.
  • Ultrasound screening every 6 months is classified as a level II recommendation.

Diagnosis

  • HCC diagnosis can involve histological analysis or non-invasive methods.
  • Histological criteria for diagnosing HCC have evolved, especially for patients with cirrhosis and small nodules.
  • The Barcelona Group's BCLC criteria is preferred for comprehensive classification of HCC.
  • The BCLC system stratifies patients based on tumor extent, liver disease progression, and overall condition, aiding in treatment decisions.

Surgical Treatment of HCC

  • Surgical options for HCC include liver resection (LR) and liver transplantation (Tx), both potentially curative.
  • Liver resection can be performed via open surgery or laparoscopic techniques.
  • Radiofrequency ablation (RFA) is another curative method, done with imaging guidance or surgically.
  • Surgical treatments carry morbidity and mortality risks, primarily due to underlying liver cirrhosis in most patients.
  • Treatment modality selection is guided by prognostic criteria to balance cure potential with surgery risks.

Indication Criteria for Liver Transplantation for HCC

  • Milan Criteria (MC) are standard for liver transplantation in HCC patients.
  • Eligibility includes a single tumor ≤5 cm or up to three tumors ≤3 cm without vascular invasion.
  • Meeting MC leads to comparable 5-year survival rates with non-tumor transplants.
  • Transarterial chemoembolization (TACE) utilizes cytostatic agents dissolved in Lipiodol, effective for unresectable HCC.
  • TACE contraindications include inadequate portal vein flow and advanced hepatic insufficiency (Child-Pugh B and C).

Selected Information on Biologic Therapy Sorafenib

  • Sorafenib is the first-line treatment for inoperable or metastatic hepatocellular carcinoma.
  • Indicated for patients with Child-Pugh class A and B liver function.
