Background

  • Most common form of liver cancer[1]
    • 5 new cases per 100,000 in western countries
    • > 100 per 100,000 in Southeast Asia and sub-Saharan Africa
  • Mean survival of 6-20 months, steady over the years despite progress in diagnosis and therapies directed at HCC
  • Surgical resection with transplantation, remains the best chance for cure
    • However, < 20% of patients meet criteria for resection at time of diagnosis[2]
    • Thus, early diagnosis is the most important step in managing HCC

Clinical Features

Differential Diagnosis

Evaluation

  • LFTs, CBC, BMP, GGT
  • Ultrasound
  • Initial contrasted CT
  • Multiphasic contrasted CT and MRI non-emergently
  • Biopsy
  • Surveillance with alfa-fetoprotein (AFP > 400 ng/mL) in combination with US[4]

Management

Disposition

  • Discussion with oncologist for first time diagnosis
  • Dependent on complications and comorbidities
