Liver Cancer Flashcards
What proportion of liver tumours are metastases?
90%
What are common sites for liver mets to spread from?
- Stomach
- Colon
- Pancreas
- Bone - leukaemia/lymphoma
- Carcinoid tumours
- Breast
- Bronchus
What are symptoms of liver tumours?
- Fever
- Malaise
- Anorexia
- Decreased weight
- RUQ pain
- Jaundice - late unless cholangiocarcinoma
What are signs that someone may have a luiver tumour?
- Hepatomegaly
- Signs of chronic liver disease +/- evidence of decompensation
- Abdominal masses
- Liver bruit
What are causes of hepatocellular carcinoma?
- HBV
- HCV
- Cirrhosis - alcohol, haemochromatosis, PBC
- NAFLD
- Anabolic steroids
- Aflatoxin
What sex does HCC occur most commonly in?
Males
What investigations would you consider doing if you suspected liver cancer?
- Bloods - FBC, U+E’s, Clotting, LFTs, hepatitis serology, alpha-fetoprotein
- Imaging - US/CT, MRI, ERCP (if chlangiocarcinoma suspected),
- Other - biopsy
If secondary mets found, perform CXR/Mammography/colonoscopy/CT/MRI/marrow biopsy when looking for primary
What specific type of imaging would you use in suspected HCC?
3-phase CT - delayed wash-out in a suspected mass
What might you find on FBC in someone with HCC?
- Microcytic anaemia - due to bleeding in e.g. alcoholic liver cirrhosis
- Thrombocytopenia - indicative of portal hypertension due to cirrhosis
What might you see on U+E’s in someone with HCC?
- Hyponatraemia - volume overload/diuretic use
- Increased Urea - secondary to prerenal azotaemia, AKI, cCKD, or hepatorenal syndrome.
What might you see on LFTs in someone with liver cancer?
- ALT/AST increased
- ALP increased
- Bilirubin increased
- Low albumin
What might you find on hepatitis screening in someone with suspected HCC?
Hepatitis B/C
What tumour marker is used in the detection of HCC?
Alpha-fetoprotein
What imaging would you use first in someone who you suspected had liver cancer?
US of liver - poorly defined margins, and course, irregular internal echoes
Hwo would you manage HCC?
Early disease
- Consider resection - if < 3cm
- Consider Liver transplantation +/- TACE +/- RFA
Intermediate disease
- Transcatheter arterial chemoembolization (TACE)
- Percutaneous ablation
Advanced
- Chemotherapy
