Study Notes
Primary Liver Tumors
-
Hepatocellular Carcinoma (HCC): Most common primary liver tumor
- Often associated with chronic liver disease (chronic hepatitis B and C, alcoholic cirrhosis, Wilson's disease, hemochromatosis, alpha-1 antitrypsin deficiency).
- Aflatoxin Exposure: A toxin from Aspergillus fungus contaminates corn, soy, and peanuts in developing countries. High intake of contaminated foods can cause HCC.
- Screening: Important in high-risk patients (chronic hepatitis). Imaging studies are used.
- Symptoms: Often asymptomatic early. Enlarged liver, obstructive jaundice, ascites, hypoglycemia (large tumors)
- Hypoglycemia Mechanism: High metabolic rate of large tumors consumes glucose. Rarely can produce insulin-like growth factor 2.
- Erythrocytosis: Secretion of erythropoietin.
- Budd-Chiari Syndrome: Compression of hepatic veins (by tumor) leads to blood clots, abdominal pain, ascites, hepatomegaly.
- Alpha-fetoprotein (AFP): Elevated in HCC, but also in chronic liver disease. Monitoring changes is helpful.
- Diagnosis: Imaging (CT, MRI, ultrasound). Biopsy for definitive diagnosis.
- Metastasis: Relatively rare at diagnosis. Usually spreads via the blood to the lungs and bones.
- Poor Prognosis: Median survival is 6-20 months post-diagnosis.
- Treatment: Complex and often poorly responsive to chemo/radiation. Surgical excision (rare), liver transplantation, radiofrequency ablation, chemoembolization.
Benign Liver Tumors
-
Hepatic Adenoma: Benign tumor from epithelial cells.
- Common in women (20s-40s).
- Often asymptomatic, discovered incidentally.
- Risk factors: Oral contraceptives, anabolic steroids.
- Clinical concern: Rupture during pregnancy. Potential excision/ablation.
-
Hepatic Hemangioma: Most common benign liver tumor. Composed of vascular spaces.
- Often discovered incidentally (imaging).
- Biopsy is not recommended.
-
Angiocercoma: Malignant vascular tumor.
- Rare. Associated with vinyl chloride (PVC plastic production) and arsenic exposure.
Liver Metastasis
-
More common than primary liver tumors.
- Originates from other areas in the body.
- Common sources: GI tract, breast, lung.
- Recognition: Multiple nodules on imaging, not solitary like primary liver tumors.
