Overview
Other diagnostic studies for hepatocellular carcinoma include laparoscopy and biopsy.
Other Diagnostic Studies
Liver Biopsy
The diagnosis of hepatocellular carcinoma is confirmed by percutaneous biopsy and histopathologic analysis.
- Core liver biopsy is the gold standard test for the diagnosis of hepatocellular carcinoma.
- Sample of the liver is obtained by:[1]
- Percutaneous
- Transjugular
- Laparoscopic radiographically- guided fine-needle approach
- Percutaneous biopsy of focal lesions may be performed in combination with either ultrasound or CT imaging.[2]
- Percutaneous liver biopsy remains the cornerstone of diagnosis. It is quick and simple to perform liver biopsy in a patient with normal platelet count and INR.[3]
- Two out of the following three positive stains upon liver biopsy confirm HCC:[4][5]
- A biopsy is not necessary if the clinical, laboratory, and radiologic data suggest hepatocellular carcinoma.
- Liver biopsy may be suggestive of etiology:
- Alcoholic liver disease : Liver biopsy may show hepatocyte necrosis, presence of mallory bodies, neutrophilic infiltration and perivenular inflammation.
- Primary biliary cirrhosis : Gold standard diagnostic modality is the detection of antimitochondrial antibodies along with liver biopsy as confirmation if florid bile duct lesions.
- There is a small but significant risk of liver biopsy, and the underlying cirrhosis in the patients with HCC itself predisposes for complications due to liver biopsy.[6]
- Risks of liver biopsy include:
- Hemorrhage
- Biliary peritonitis
- Hematoma
- Perforation of other viscera
- Mortality rates of between 0.01% and 0.1%
- Patients with moderate coagulopathy:
- Plugged liver biopsy : injection of gelatin sponges or metal coils down the tract after biopsy
- Laparoscopic liver biopsy performed on a sedated patient with moderate coagulopathy
- Advantage: allows direct visualisation of the liver
- Patients with severe clotting disorders:
- Transjugular liver biopsy:
- Risk of intraperitoneal bleed is less
- Disadvantages:
- Transjugular liver biopsy:
The comparison table for diagnostic studies of choice for hepatocellular carcinoma:[7]
| Diagnostic Test | Sensitivity | Specificity |
|---|---|---|
| Percutaneous Ultrasound guided liver biopsy | 90% | 91% |
| Percutaneous CT guided liver biopsy | 92% | 98% |
Sequence of Diagnostic Studies
The core needle biopsy should be performed when:[8]
- A positive hepatic leision is detected in the patient on imaging studies.
- The patient has underlying risk factors i.e HBV infection,HCV infection or liver cirrhosis.
Diagnostic Criteria
- Hepatocellular carcinoma may be diagnosed at any time if the following criteria is met:
- Two out of the following three positive stains upon liver biopsy confirm HCC:[4]
Hepatic venous pressure gradient measurement
- Hepatic venous pressure gradient (HVPG) measurement is the difference between hepatic venous wedge pressure (HVWP) and free hepatic venous pressure (FHVP).
- HVPG reflects the intra-sinusoidal pressure.[9]
- The HVPG of over 10 mmHg is associated with a 6-fold increase of HCC risk.[10]
- HVPG is measured through insertion of a catheter in right internal jugular vein.[11]

The main cause of mortality after percutaneous liver biopsy is intraperitoneal haemorrhage as shown in a retrospective Italian study of 68,000 percutaneous liver biopsies in which all six patients who died did so from intraperitoneal haemorrhage. Three of these patients had had a laparotomy, and all had either cirrhosis or malignant disease, both of which are risk factors for bleeding.
