HCC RPA Flashcards
Most common primary liver cancer is …
HCC
90% HCC have…
Cirrhosis
In MAFLD, 30% can develop HCC without cirrhosis
Causes of HCC
Hep B/C - decreasing in Australia
ETOH related liver disease - increasing in Australia
Metabolic liver disease (MAFLD) - increasing in Australia
Prevention of metabolic associated HCC
Aspirin
Statin
Metformin
Does aspirin reduce HCC and liver-related mortality?
Yes
Recent NEJM trial
Clinical presentation of HCC
Screening program
- 6 monthly USS and AFP in cirrhosis and some chronic Hep B
Abdo pain, new onset ascites (vascular invasion), intraabdo haemorrhage
Incidental lesion on imaging
During transplant assessment in patients with decompensated disease
Incidental at time of transplant
HCC surveillance how?
USS 6 monthly
AFP
CT/MRI not routinely used but may be used in obesity
Who should have HCC surveillance?
Cirrhosis - up to 7% chance of HCC every year
People with chronic hep B infection without cirrhosis Asian men >40 Asian women >50 Subsharan african >20 ATSI >50
Liver Nodule at imaging
<1cm - repeat USS at 4/12 –> if growing, changing, the need contrast CT
> 1cm - multiphase contrast enhanced CT/MRI –> If HCC hallmark then no need for biopsy and can be diagnosed with HCC. If atypical features, then need biopsy (not done often)
Features of HCC in 4 phase multislice helical CT scan
Arterial hyperenhancement
Washout on portal and delayed phase
Management of HCC
BCLC staging system –> guide treatment
Options
Local Ablation (lesions <3cm) with ethanol or thermal
Resection
Transplant
Transarterial chemoembolisation (TACE) - delivery of chemotherapy through artery (femoral) to occlude arterial supply; cisplatin or doxorubicin or drug eluding beads
Selctive internal radiation therapy (SIRT) - delivery of radiation via hepatic artery. Difficult to deliver, risk of hepatotoxicity, very specialised, $$$ and not funded, not incooperated in guidelines due to limited evidence hence not used much.
Systemic therapy - TKi (sorafenib, lenvatinib) quite toxic; immunotherapy
Best supportive palliative care
When to use systemic therapy in HCC?
ECOG 1
Not amenable to other therapies (lots of intrahepatic disease)
Good liver function
Advanced HCC
Which systemic therapies are available in HCC?
1st line: Sorafenib, lenvatinib - Anti VEGF TKI.
2nd line: regorafenib, cabozantenib (not PBS at the moment)
NEW
Atezolizumab (anti-PDL1) + bevacizumab (anti VEGF)
- Superior to sorafenib, lenvatinib
- New 1st line therapy
Sorafenib side effects
Diarrhoea
Hand foot skin reaction
LOA, LOW
Lenvatinib side effects
Refractory HTN
