- Patients must have given written informed consent.
- Female or male aged 18 years and over.
- Diagnosis of HCC established according to the Netherlands HCC guideline criteria (in line with American AASLD criteria): nodule >1 cm in a patient at risk for HCC, with combination of arterial hypervascularity and venous or delayed phase wash-out on multiphase CT-scan or MRI-scan.2, 4 LR-5 and LR- 4 based on Liver Imaging Reporting and Data System can be included based on discretion of the principal investigator.

- At least one measurable liver lesion according to the modified RECIST criteria.(26)
- Negative pregnancy test for women of childbearing potential. Female patients of childbearing potential should use a highly effective acceptable method of contraception (oral contraceptives, barrier methods, approved contraceptive implant, long-term injectable contraception, intrauterine device or tubal ligation) or should be more than 1 year postmenopausal or surgically sterile during their participation in this study (from the time they sign the consent form), to prevent pregnancy.
Exclusion Criteria:
A potential subject who meets any of the following criteria will be excluded from participation in this study:
- Evidence of significant extrahepatic disease (MRI-scan liver and multiphase abdominal CT as well as a thoracic CT are routinely performed at screening).
- Hepatic radiation therapy within the last 4 weeks before the start of study therapy.
- Previous or current treatment with RE. Previous treatment with TACE, surgery, RFA, and previous or current treatment with sorafenib are allowed.

Tumor marker changes will be expressed as a percentage of the pre-treatment values.

Response will be measured according to modified RECIST.
The correlation between non-tumor liver absorbed dose in Gy and rate of unacceptable toxicity.

5. Study Description
Brief Summary
Patients with hepatocellular carcinoma often die from intrahepatic disease because current treatment options are limited. Local treatment using 166Ho-radioembolization (166Ho-RE) offers a safe and effective treatment. Because 166Ho-microspheres are used as a scout dose for treatment simulaton and for the actual treatment itself, a tailored approach can be used. This concept has proven to be more predictive than the 90Y-radioembolization concept (current standard-of-care), which is a based on a surrogate scout dose (i.e. 99mTc-MAA). A personal treatment plan may be used for 166Ho-radioembolization to optimize efficacy, based on scout dose distribution. However, individualized treatment planning inherently leads to treatment doses that deviate from the currently approved 'one-size-fits-all' approach (i.e. 60 Gy average absorbed dose for all patients). Therefore, safety of individualized 166Ho-RE will be evaluated first to validate safety and confirm safety thresholds. These thresholds will be used in subsequent randomized controlled studies.
Detailed Description
The presented study proposal is a sequel study after a successful completion of the HEPAR Primary study (all patients were treated, last follow-up visit planned for August 2020). In the HEPAR Primary study, all treatments were planned using one compartment modeling, which included the target volume without distinction between tumor and non-tumor compartments. Each patient was treated with an average absorbed dose of 60 Gy in the target volume. In some patients this treatment approach resulted in a high tumor and low normal liver absorbed dose, in others this resulted in the opposite. No distinction was made because thresholds for a safe normal liver and effective tumor absorbed dose were not known, since HEPAR Primary was the first clinical study on 166Ho-RE in HCC. The study confirmed safety of a 60 Gy average absorbed dose and gave insights in the previously unknown thresholds for a safe normal liver and effective tumor absorbed dose.
The primary hypothesis of the iHEPAR study is that dosimetry-based individualized treatment planning is at least as safe as standard of care one compartment treatment planning, used in HEPAR Primary, but with the potential of improved treatment outcomes. One compartment modeling has the inherent risk of under- or over-dosing. Dosimetry-based individualized treatment planning aims for an effective tumor absorbed dose, while keeping the non-tumor absorbed dose within safety limits. So far, only one compartment modeling was established as a safe and effective treatment approach in 166Ho-RE. This phase II study aims to evaluate the safety and efficacy of dosimetry-based individualized 166Ho-RE in HCC. This data will be used for the design of future randomized controlled trials.
