LIVER SBRT FOR
HCC AND LIVER METASTASES

When surgery, RFA, and TACE are not options โ€” SBRT delivers ablative radiation to liver tumours with precision, sparing healthy liver and achieving durable local control.

How Liver SBRT Works

Liver SBRT uses real-time image guidance and respiratory motion management to target liver tumours with millimetre accuracy, delivering ablative doses across 3โ€“6 fractions while protecting the remaining liver parenchyma.

  • HCC (Hepatocellular Carcinoma)

    For patients with cirrhosis who are not surgical candidates and have lesions not amenable to RFA or TACE, SBRT provides a bridging or definitive treatment with well-documented local control and safety in Child-Pugh A liver function.

  • Liver Metastases

    Colorectal, breast, and neuroendocrine liver metastases respond well to SBRT. It is preferred over RFA for lesions >3 cm, centrally located tumours, or those adjacent to major hepatic vessels where thermal ablation carries high risk.

Liver SBRT: Key Outcome Data

  • 80โ€“90%2-Year Local Control (HCC)Across prospective series and RTOG 1112 data
  • 75โ€“85%2-Year Local Control (Liver Mets)For colorectal and other histologies
  • 6โ€“7%Grade โ‰ฅ3 Hepatic ToxicityMaintained with mean liver dose constraints
  • 3โ€“6Fractions RequiredTypically completed in 1โ€“2 weeks

Patient Eligibility: HCC vs Liver Metastases

Eligibility differs between HCC (where liver function is critical) and metastatic disease (where tumour burden and systemic disease status guide selection).

CriteriaHCCLiver Metastases
Liver functionChild-Pugh A preferred; selected CP-B7Normal function expected; adequate liver reserve required
Tumour sizeUp to 6 cm in most series; larger possibleBest evidence for โ‰ค5 cm per lesion
Number of lesions1โ€“3 liver lesions1โ€“5 lesions (oligometastatic setting)
Prior treatmentPost-TACE, bridge to transplantPost-systemic therapy; prior RFA recurrence
ContraindicationsChild-Pugh C; prior whole-liver RTDiffuse hepatic metastases; insufficient liver volume

Liver SBRT vs RFA and TACE

Treatment choice depends on tumour size, location, vascular proximity, and liver reserve.

SBRT Preferred When

  • Tumour >3 cmRFA has incomplete ablation rates >50% for lesions above this size
  • Adjacent to major vesselsHeat-sink effect reduces RFA efficacy near hepatic veins/portal structures
  • Multiple prior RFA attempts failedSBRT can achieve control in RFA-refractory lesions
  • Portal vein tumour thrombus (HCC)SBRT with PVTT is an accepted indication in Asian guidelines

RFA/TACE Preferred When

  • Tumour โ‰ค2 cmRFA achieves near-complete ablation with minimal toxicity
  • Child-Pugh C with preserved portal flowTACE may be preferred to preserve liver function before transplant
  • Multifocal bilobar HCCTACE covers multiple segments in one session

Local Control by Tumour Type

Liver SBRT delivers consistent local control across primary and metastatic hepatic tumours.

2-Year Local Control Rates

  • HCC (Child-Pugh A)87%
  • Colorectal Liver Metastases82%
  • Breast Cancer Liver Metastases80%
  • Neuroendocrine Liver Metastases85%

Frequently Asked Questions

Liver SBRT

  • Can liver SBRT be given to patients with cirrhosis?

    Yes, in selected patients. Child-Pugh A cirrhosis is the standard eligibility criterion, with published safety data showing acceptable liver toxicity when mean liver dose and volume constraints are respected. Child-Pugh B7 patients can be considered at experienced centres with careful dose planning. Child-Pugh C cirrhosis is generally a contraindication due to limited hepatic reserve.

  • Is liver SBRT effective for colorectal liver metastases?

    Yes. Prospective data show 2-year local control rates of 75โ€“85% for colorectal liver metastases treated with SBRT. It is particularly valuable for patients with oligometastatic disease after chemotherapy, or for those with RFA-unsuitable lesion locations. Combined with systemic therapy, liver SBRT can contribute to long-term disease control in oligometastatic colorectal cancer.

  • How is liver motion managed during SBRT?

    Liver moves 1โ€“3 cm with each breath cycle. Centres use respiratory motion management strategies including abdominal compression, active breath hold, or real-time tumour tracking (e.g., CyberKnife, gating) to ensure the beam tracks the tumour. Daily CBCT or MRI guidance confirms tumour position before each fraction.

  • Can liver SBRT be used as a bridge to transplantation in HCC?

    Yes. SBRT is increasingly used as a bridging therapy to liver transplantation in HCC patients awaiting organ availability. It can achieve durable local control for 6โ€“18 months, preventing tumour progression beyond Milan criteria during the waiting period. Several transplant centres now accept SBRT as equivalent to locoregional therapy for downstaging or bridging.

  • Where can I access liver SBRT in India or China?

    Liver SBRT is available at major hepatobiliary oncology centres in India (Tata Memorial Hospital, AIIMS New Delhi, HCG network) and China (Zhongshan Hospital Shanghai, PUMCH Beijing, Sun Yat-sen University Cancer Centre). CancerFax can assess your eligibility and coordinate consultations at the most appropriate centre based on your liver function and tumour characteristics.
