A Study of Standard Of Care Versus Radio Ablation in Early Stage HCC (SOCRATES HCC)

4. juni 2026 opdateret af: University Health Network, Toronto

A Randomized Controlled Trial of Standard Of Care Versus Radio Ablation in Early Stage Hepatocellular Carcinoma

This Phase II Prospective, parallel and open-label randomised control trial will investigate whether a radiotherapy technique (called SABR) can treat early stage liver cancer more effectively than current treatments which use heating probes directly inserted into the tumour or chemotherapy or radioactive particles injected into the blood supply of the tumour. Investigators hypothesize SABR will result in higher rates of freedom from local progression (FFLP) at 2 years compared to percutaneous thermal ablation ± TACE or transarterial therapies (TACE/TARE).The study will also look at other important outcomes such as progression free survival, overall survival, side effects, quality of life and people's experiences of their treatment.

Detaljeret beskrivelse

The SOCRATES randomised controlled trial will assess the efficacy, toxicity, HRQoL profile and cost effectiveness of SABR compared to the current SOC treatment in patients with first diagnosis of unresectable, single nodule HCC. Participants will be placed into one of two groups based on the size of their tumour and whether thermal ablation is an appropriate treatment for them. The study will include about 218 participants in total. Participants will be randomly assigned to receive either SABR or the current standard of care. Standard care may include thermal ablation, transarterial chemoembolisation (TACE), or transarterial radioembolisation (TARE).

Beskrivelse

Inclusion Criteria:

1) Histological or radiological diagnosis of single, new HCC with largest diameter =8 cm (BCLC stage 0 or A).

  • a) If prior history of HCC, the prior HCC must have been:
  • Early stage, solitary HCC, =5 cm in size and,
  • Have arisen within a different liver segment to the current HCC and,
  • Treated with curative intent therapy >2 years prior with no evidence of active disease at the site.
  • 2) As per local multidisciplinary HCC meeting consensus patient is suitable for percutaneous thermal ablation and/or transarterial therapies and not suitable for or declined liver resection and not planned for liver transplantation.
  • 3) Child-Pugh score =B7* with no or diuretic-controlled ascites
  • 4) ECOG performance status =2
  • 5) Platelets =50x109/L, Haemoglobin =80 g/L, Neutrophils =1.0x109/L, INR <1.8 (except if on therapeutic anticoagulation)
  • 6) 18 years of age or older and able to provide written consent

Exclusion Criteria:

  • 1) Presence of multifocal HCC, macrovascular invasion or extrahepatic disease
  • 2) Prior treatment for any HCC within last 2 years.
  • 3) Clinically evident ascites or hepatic encephalopathy
  • 4) Prior abdominal radiation therapy that would preclude the delivery of protocol defined SABR to the tumour.
  • 5) Untreated Hepatitis B or C

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Stråleterapi
Stråling: Stereotactic Ablative Body Radiotherapy (SABR)
SABR will be delivered in 3 or 5 outpatient treatment sessions (each 20 to 45 minutes in duration) spaced out over 1 to 2 weeks. The exact number of treatment sessions received, and the duration of each session depends on the size and location of the liver cancer.
Andet: Standard Of Care Treatment
Stråling: Therapies
Patients will receive standard of care treatment (SOC) as per their institution's local practice that will be administered by a doctor called an Interventional Radiologist. The therapies offered will depend on the size and location of the liver cancer and may include one or a combination of radiofrequency ablation (RFA) / microwave ablation (MWA) and/or transarterial chemoembolization (TACE) / transarterial radioembolisation (TARE).

Patient reported outcomes (EORTC QLQ-C30)
Tidsramme: 2 Years

The C30 is a 30-item instrument that evaluates HRQOL comprised of five functional scales (physical, cognitive, emotional, social, and role) as well as nine symptom scales (fatigue, pain, nausea/vomiting, dyspnea, insomnia, anorexia, constipation, diarrhea, and financial), and a global QoL scale.

Responses are scored on a linear scale from 0 to 100. Higher scores on functioning/global health indicate a better, healthier state. Higher scores on symptom scales indicate a higher symptom burden or worse condition.
2 Years
Patient reported outcomes (QLQ-HCC18)
Tidsramme: 2 Years
QLQ-HCC18 is a questionnaire where patients report symptoms or problems on a scale of 1 (not much) to 4 (very much). Higher scores on symptom scales indicate a higher symptom burden or worse condition.
