Overview
Fibrolamellar hepatocellular carcinoma (FL-HCC) is a rare variant of hepatocellular carcinoma characterized by a distinctive histological appearance featuring laminated fibrous layers and typically affects young patients without underlying liver disease 1.Diagnosis
Histological Features: Presence of laminated fibrous layers and eosinophilic cells 1.
Imaging: Contrast-enhanced CT or MRI showing characteristic patterns of enhancement 1.
Tumor Markers: Elevated serum alfa-fetoprotein (AFP) levels, though often less pronounced than in conventional HCC 1.
Genetic Testing: Identification of the DNAJB1-PRKACA fusion gene is diagnostic 1.Management
Surgical Resection: First-line treatment for patients with resectable disease 1.
Liver Transplantation: Considered for eligible patients with early-stage disease 1.
Systemic Therapy: Limited data; clinical trials exploring targeted therapies are recommended 1.
Radiation Therapy: Role is evolving; may be considered in specific cases 1.Special Populations
No Specific Data: The provided abstracts do not cover special populations such as pregnancy, pediatrics, elderly, or specific comorbidities 1.Key Recommendations
Surgical Resection for Resectable Disease: Prioritize surgical resection for patients with resectable FL-HCC (Evidence: Strong 1).
Consider Liver Transplantation for Early-Stage Disease: Evaluate eligible patients for liver transplantation in early-stage FL-HCC (Evidence: Moderate 1).
Genetic Testing for Diagnosis: Utilize genetic testing for DNAJB1-PRKACA fusion gene to confirm diagnosis (Evidence: Strong 1).References
