Hepatocellular Carcinoma |(malignant) Flashcards
Which type of people does it affect?
Those with a pre-existing liver disease eg liver cirrhosis or chronic hepatitis
What is the aetiology of this cancer?
Liver cirrhosis in 80% of cases
Additional risk factors - chronic hepatitis B and C
Alcoholic liver disease
Haemochromatosis
Wilson’s disease
Autoimmune hepatitis
What are the clinical features of this cancer?
Usually asymptomatic apart from symptoms of underlying disease
Possible symptoms in advanced disease - weight loss, anorexia, hepatomegaly, RUQ tenderness, jaundice, ascites
Which diagnostic tests should be carried out?
Initial - US abdomen
CT or MRI if the following are detected - lesion greater or equal to 10mm, lesion of any size and Alpha fetoprotein more than or equal to 20ng/dl
Perform liver biopsy in the following cases - inconclusive multiphase imaging (ct or mri). Liver lesions suspicious for HCC in patients without cirrhosis
Lab studies to evaluate liver function and assess for underlying aetiologies
What are the supportive findings on an US abdomen?
Solid nodules typically greater than or equal to 10mm of varying homogeneity or echogenicity (ability for tissue to reflect sound waves) with irregular borders
Signs of cirrhosis may be present
What can you find on a CT or MRI scan?
A lesion with irregular borders and possible signs of local invasion
What will the lab studies reveal?
CBC - thrombocytopenia or paraneoplartic erythrocytosis
Liverchermistries - may be abnormal in pre-existing liver disease or advanced malignancy
Coagulation screen - may be abnormal in pre-existing liver disease or advanced malignancy
Serum AF - elevated
What will the lab tests reveal for suspected paraneoplastic syndrome?
Blood glucose - hypoglycaemia
Serum calcium - hypercalcemia
Lipid panel - hypercholesterolemia
What is the treatment for very early stage HCC or early stage HCC?
First line - surgical resection of liver if minimal disease. If significant disease to liver - transplant (Milan criteria)
Alternative - ablative therapy eg radiofrequency ablation
What is the treatment for intermediate stage HCC?
Locoregional therapy with - trans catheter chemoemoblization, trans arterial radioembolization
What is the treatment for advanced HCC?
Systemic chemotherapy - first line is targeted treatment
Alternatives include non targeted chemotherapy, hepatic sartorial infusion chemotherapy
What is the treatment for end stage HCC?
Typically palliative care only
What is the prognosis?
5 year survival rate of early stage - 70%
5 year survival rate for advanced stage - 20%
What are the preventive measures for HCC?
Reduce risk of blood borne viruses
Maintain alcohol intake within normal limits
Manage obesity
