Recommended in the guidelines
ESMO, EASL and NCCN guidelines acknowledge the potential benefits of SIR-Spheres® Y-90 resin microspheres for treatment of hepatocellular carcinoma.
Hepatocellular carcinoma: ESMO Clinical Practice Guidelines for diagnosis, treatment and follow-up (2018)1
SIRT is not recommended as first-line therapy for HCC patients in intermediate and advanced stage.
SIRT may be considered instead of TACE to avoid drop out from a transplant list in reducing tumour progression
SIRT may be considered as an alternative treatment option in patients with liver-confined disease and preserved liver function after TACE (after TACE failure/ refractoriness)
SIRT may be considered as an alternative treatment option in patients with liver-confined disease and preserved liver function in whom systemic therapy is not feasible.
EASL Clinical Practice Guidelines: Management of hepatocellular carcinoma (2018)2
- SIRT showed better tumour control than TACE and could therefore reduce drop-out from transplant waiting list
- SIRT induces substantial contralateral hypertrophy and might prepare or select patients with borderline resectable HCC for surgery
BCLC B (SIRT vs. TACE)
- SIRT induces less toxicity
- SIRT provides significantly longer TTP and better tumour control but no better OS
- SIRT maintains higher QoL
BCLC C (SIRT vs. Sorafenib – SARAH / SIRveNIB)
- No statistically significant differences in OS were observed
- Response rates were significantly higher with SIRT
- Survival benefit compared to sorafenib is still not proven hence SIRT should only be adopted after MDT discussion
NCCN Guidelines Version 2.2019; Hepatobiliary Cancers3
- Loco-regional therapies# such as SIRT* should be considered in patients who are not candidates for surgical curative treatments
- As arterially directed therapy‡ SIRT is relatively contraindicated in patients with bilirubin >3 mg/dL unless segmental treatment can be performed
- SIRT with yttrium-90 microspheres has an increased risk of radiation-induced liver disease in patients with bilirubin over 2 mg/dL
- All tumours irrespective of location may be amenable to SIRT
- SIRT should be considered as bridge for other curative therapies
- SIRT may be used as monotherapy or in combination with ablation to treat lesions 3 to 5 cm to prolong survival
- SIRT should be considered for unresectable/inoperable lesions >5 cm
- See above: All tumours irrespective of location may be amenable to SIRT
- SIRT should be considered in highly selected patients in the presence of limited tumour invasion of the portal vein
- Sorafenib may be appropriate following SIRT in patients with adequate liver function once bilirubin returns to baseline if there is evidence of residual/recurrent tumour not amenable to additional local therapies
# Loco-regional therapies: ablation, arterially directed therapies, and radiotherapy
*SIRT: Selective Internal Radiation Therapy, also known as Radioembolisation (RE)
‡ Arterially directed therapies: bland trans-arterial embolisation (TAE), trans-arterial chemoembolisation [TACE, DEB-TACE] and radioembolisation (RE) with yttrium-90 microspheres
