Overview Hepatocellular carcinoma (also known as hepatoma ) is a primary cancer arising from hepatocytes in predominantly cirrhotic liver. Hepatocellular carcinoma is a leading cause of death worldwide, and cirrhosis is the main risk factor. Infection with hepatitis B and hepatitis C is the main cause of underlying liver disease. Prevention of chronic liver disease would greatly reduce incidence. Early tumour diagnosis through screening of at risk groups is cost effective
The liver is wedge-shaped and is present in the right upper quadrant of the abdomen. The liver typically extends from the fifth intercostal space to the right costal margin in the midclavicular line.

| In thin people |
| During deep inspiration |
| In the setting of a right pleural effusion |
| When emphysema results in hyperinflation of the chest with diaphragmatic descent and downward displacement of the liver |

General
Chronic liver disease screen
Other investigations for Differential Diagnosis
| Remember Screening with ultrasound for Hepatocellular carcinoma is recommended for patients with liver cirrhosis (as well as of other risk factors) every 6 months. |
Child-Pugh Score (Determines liver function)
Barcelona clinic liver cancer (BCLC) staging classification - to help guide management - looks at the following factors:
| Barcelona clinic liver cancer | Feature |
| Stage 0 (very early stage) | Asymptomatic early tumours |
| Stage A (early stage) | Asymptomatic early tumours |
| Stage B (intermediate stage) | Asymptomatic multinodular tumours |
| Stage C (advanced stage) | Symptomatic tumours and/or invasive tumours |
| Stage D (end-stage) | Symptomatic treatment |
Barcelona clinic liver cancer (BCLC) staging classification - to help guide management - looks at the following factors:
| Barcelona clinic liver cancer | Feature | Treatment |
| Stage 0 (very early stage) | Asymptomatic early tumours | Resection |
| Stage A (early stage) | Asymptomatic early tumours | Resection, percutaneous ablation, transplantation |
| Stage B (intermediate stage) | Asymptomatic multinodular tumours | Intra-arterial therapies (chemoembolisation and radioembolisation) |
| Stage C (advanced stage) | Symptomatic tumours and/or invasive tumours | Sorafenib, phase II trial agents, or palliative treatments |
| Stage D (end-stage) | Symptomatic treatment |
Treatment
| Pharmacology Sorafenib is indicated for the treatment of unresectable hepatocellular carcinoma and advanced renal cell carcinoma. It is a multikinase inhibitor, by inhibiting these kinases, genetic transcription involving cell proliferation and angiogenesis is inhibited. Sorafenib has been shown to prolong survival and is regarded as the standard of care. The adverse reactions observed at this dose were primarily diarrhoea and dermatologic events |
Complication
Prognosis Hepatoma is a very aggressive tumour. The clinical course and survival depends upon the stage and overall functional status of the liver
| Barcelona clinic liver cancer | Feature | Prognosis |
| Stage 0 (very early stage) | Asymptomatic early tumours | - |
| Stage A (early stage) | Asymptomatic early tumours | 50-70% 5 year survival with treatment |
| Stage B (intermediate stage) | Asymptomatic multinodular tumours | 50% 3 year survivial without treatment |
| Stage C (advanced stage) | Symptomatic tumours and/or invasive tumours | 50% 6 month survival |
| Stage D (end-stage) | Symptomatic treatment | 50% <3month survival |
