The incidence of HCC is higher in areas of the world that have high hepatitis B and C carrier rates. The incidence of HCC is higher in areas of the world that have high hepatitis B and C carrier rates. HCC typically develops in the setting of chronic liver disease or cirrhosis.

Laboratory Testing-1 Liver function test abnormalities consistent with cirrhosis are frequently present since most HCC arise in the setting of cirrhosis: Thrombocytopenia Thrombocytopenia Hypoalbuminemia Hypoalbuminemia Increased PT Increased PT Increased Bilirubin Increased Bilirubin Normal or mild increase in transaminase levels Normal or mild increase in transaminase levels Normal or increased ALP level Normal or increased ALP level

Laboratory Testing-2 %75-90 of patients with HCC have an elevated AFP level. AFP levels may be elaveted other hepatic diseases such as hepatitis ( acute or chronic ) and cirrhosis. AFP levels may be elaveted other hepatic diseases such as hepatitis ( acute or chronic ) and cirrhosis. Many experts maintain that an AFP level > 500  g/L is diagnostic for HCC in a patient who is at risk for this type of cancer. Many experts maintain that an AFP level > 500  g/L is diagnostic for HCC in a patient who is at risk for this type of cancer. In patients who have AFP elevation due to HCC, the degree of elevation is not related to the stage of the tumor, size of the lesion, or prognosis of the patient. In patients who have AFP elevation due to HCC, the degree of elevation is not related to the stage of the tumor, size of the lesion, or prognosis of the patient. With tumor resection, AFP levels often return to normal. With tumor resection, AFP levels often return to normal. AFP levels are useful in monitoring patients for tumor recurrence following tumor resection. AFP levels are useful in monitoring patients for tumor recurrence following tumor resection.

Ultrasonography Small tumors are often hypoechotic but with growth, the tumor is more likely to be isoechotic or even hyperechotic. US findings that are particulary suggestive of the diagnosis are ill-defined margins and coarse, irregular internal echoes.

US findings that are particulary suggestive of the diagnosis are ill-defined margins and coarse, irregular internal echoes. Will identify most HCC but cannot reliably distinguish these lesions from other hepatic lesions. As a result, other imaging test modalities are often necessary.

The detection of a hepatic mass in combination with an AFP level > 500 mg/L is considered to be diagnostic for HCC. The detection of a hepatic mass in combination with an AFP level > 500 mg/L is considered to be diagnostic for HCC. Percutaneous ultrasound-guiged FNA of a liver mass can be done to establish the diagnosis but complications include hemorrhage and tumor seeding.

CT-Scan ( With intravenous contrast ) Can identify tumors < 1 cm. Can identify tumors < 1 cm. CT scan has greater sensivity and spesificity than US, especially for tumors < 1 cm. CT scan has greater sensivity and spesificity than US, especially for tumors < 1 cm. CT is often done to evaluate an abnormality first detectedon US. In some centers, however, it is the initial imaging modality in the patient suspected of having HCC. CT is often done to evaluate an abnormality first detectedon US.

MRI Sensitivity of MRI is similar to that of helical CT. Sensitivity of MRI is similar to that of helical CT. Nonetheless, CT is preferred over MRI because of cost. Nonetheless, CT is preferred over MRI because of cost. Consider MRI over CT scan if patient has renal insufficiency, allergy to contrast dye, or CT results that are equivocal.

Treatment-1 Surgical resection should be considered if the HCC is resectable and the patient is a candidate for resection. Surgical resection should be considered if the HCC is resectable and the patient is a candidate for resection. 1. The likelihood that resction will succesfull depends upon the size ( < 5 cm ) and location of the tumor. In addition, success is also dependent upon whether the remaining hepatic parenchyma compensate for that which is resected 1.

Lobar resection can often be performed in patients with Child’s class A cirrhosis. 3. Lobar resection can often be performed in patients with Child’s class A cirrhosis. 4. Because of the high recurrence rate after resection, postoperative adjuvant therapy should be considered. 4. Because of the high recurrence rate after resection, postoperative adjuvant therapy should be considered.

Treatment-2 Orthoptic liver transplantation has had promising results in the treatment of HCC but is limited by the long wait that is often needed for the donor liver.

Percutaneous ethanol injection and radiofrequency ablation should be considered in patients with HCC who cannot withstand resction because of poor hepatic reserve.
