Conditions

Non-Resectable Hepatocellular Carcinoma, Primary Liver Cancer

Keywords

hepatocellular carcinoma, radioembolization, TARE

Brief summary

To investigate the safety and feasibility of a personalized Ho-166-PLLA-MS TARE approach by using MRI guidance in inoperable patients with HCC.

Interventions

PROCEDUREMRI-guided radioembolization

Catheter placement will be performed using fluoroscopy, after which patients are transferred to the MRI scanner, where holmium microspheres are administered based on MRI dosimetry. Thereby, patients get a personalized dose administration.

Inclusion criteria

1. Diagnosis of hepatocellular carcinoma BCLC stage B or C 2. At least one lesion of 10 mm or more in the longest diameter on contrast-enhanced MRI/CT 3. Patient is eligible for TARE as determined by the tumour board (in Dutch: MDO) 4. Patient has a life expectancy of 12 weeks or longer 5. Patient has a WHO performance score of 0-2

Exclusion criteria

1. Extrahepatic disease that cannot be targeted during the TARE session (enlarged lymph nodes in the liver hilus are allowed) 2. Radiation therapy, chemotherapy or major surgery within 4 weeks before treatment 3. Serum bilirubin \> 2.0 x the upper limit of normal 4. ALAT, ASAT, alkaline phosphatase (AF) \> 5x the upper limit of normal 5. Leukocytes \<4.0 \* 109/L or platelet count \<60 \* 109/L 6. Significant heart disease that in the opinion of the physician increases the risk of ventricular arrhythmia. 7. Pregnancy or breast feeding 8. Disease with increased chance of liver toxicity, such as primary biliary cirrhosis or xeroderma pigmentosum 9. Patients ineligible to undergo MR-imaging (claustrophobia, metal implants, etc) 10. Portal vein thrombosis of the main branch (more distal branches are allowed) 11. Untreated, active hepatitis 12. Body weight \> 150 kg (because of maximum table load) 13. Severe allergy for i.v. contrast (Iomeron, Dotarem and/or Primovist) 14. Lung shunt \> 30 Gy, as calculated using scout dose 166Ho SPECT/CT. 15. Uncorrectable extrahepatic deposition of scout dose activity. Activity in the falciform ligament, portal lymph nodes or gallbladder are accepted. 16. Unstable final catheter position due to hepatic artery anatomy, which might lead to dislocation of the catheter during transfer to the MRI.

Design outcomes

Primary

MeasureTime frameDescription
Toxicity profile of dose administration cohorts12 months after treatmentDetermine a safe maximal healthy liver dose for personalised administration of microspheres based on (S)AEs related to liver toxicity due to radioembolisation.
Safety of MRI-guided radioembolization procedure12 months after treatmentMonitoring (S)AE's related to the investigated combination of MRI-guided 166Ho radioembolization.
Time constraints of performing intraprocedural MRI-based dosimetryduring treatment procedureTime constraints for image processing in between administration of microspheres, in order to be able to perform the procedure within half a day.
Feasibility of performing intraprocedural treatment planningduring treatment procedureThe ability of deciding on catheter positions and dose aministration during the procedure based on MRI dosimetry by comparing the standard of care treatment plan to the treatment performed during the study.

Secondary

MeasureTime frameDescription
