1
4 reasons you can die from cirrhosis
Bleeding varices
Liver cell failure
Infection
Hepatocellular carcinoma
2
Risk factors for hepatocellular carcinoma
Cirrhosis
Male
Obesity
Alcohol
3
Cause of malignant tumour in non-cirrhotic patients
Metastatis
4
Cause of malignant tumour in cirrhotic patients
70% hepatocellular carinoma
5
Clinical features of hepatocellular carinoma
Worsening liver function
Weight loss
6
Treatment for cirrhosis
Surveillance- 6 month ultrasound scan
7
Blood test for hepatocellular carcinoma
Alpha feto-protein (liver cells often synthesise this) Although by the point this is detected, usually too poor a prognosis for surgical treatement
8
Macroscopic structure of HCC
Expansile soft nodules, often green (bile)
9
What other hepatic vessels are affected by HCC?
Portal vein 60%
Hepatic vein 20%
Bile duct 5%
10
Is HCC usually unifocal or multifocal in cirrhosis?
Multifocal
11
Microscopic structure of HCC
Cancer cells may produce bile
12
Prognosis of HCC
Very poor (
13
Treatment for HCC
Surgery- if non cirrhotic or small and peripheral
Transplant
14
In what circumstances would you consider liver transplant with HCC
If tumour is smaller than 5cm or 3 or less tumours smaller than 3cm
15
Treatment for non-resectable tumours e.g. multiple, large, metastasised
Ablation-radiofrequency
Embolisation
Chemotheraphy-sorafenib
16
Solitary tumour without vascular invasion
pT1
17
Solitary tumour with vascular invasion or multiple tumours, none more than 5 cm in greatest dimension
PT2
18
Multiple tumours, any more than 5cm
PT3a
19
Single or multiple tumours of any size involving a major branch of the portal vein or hepatic vein.
pT3b
20
Tumour(s) with direct invasion of adjacent organs other than the gall bladder or with perforation of visceral peritoneum
pT4
21
What is more common, primary or secondary liver cancer?
Secondary (more common that tumour metastasise to the liver)
22
Where might a tumour have metastasised from if it presents in the liver with few large nodules?
Large bowel
23
Treatment for tumours in the liver than have metastasised from the large bowel
Surgery
24
Where might tumours in the liver that are multinodular or infiltrative, come from?
Lung, pancreas, breast, stomach, melanoma
25
Treament for secondary metastases to the liver which present as multinodular or infiltrative?
Biopsy to decide best treatment
26
Primary liver cancer (adenocarcinoma)
Cholangiocarcinoma
27
2 sites of cholangiocarcinoma
Intrahepatic
Perihilar
28
Cholangiocarcinoma from small intrahepatic ducts, where are they found, when do they present and what are the risk factors?
Intrahepatic
Peripheral
Late
None or cirrhosis
29
Cholangiocarcinoma from large ducts, causing obstructive jaundice early, risk factors
Perihilar
Bile duct disease
Primary sclerosing cholangitis
Liver flukes
