Brief Summary
This is a observational, prospective, single arm, proof of concept study to assess safety, feasibility, and potential efficacy of combining Yttrium-90 transarterial radioembolization(TARE) with standard systemic therapy in clinical practice for potentially resectable patients with colorectal liver metastases (CRLM). Alternatively, resectability will also be evaluated. The investigators hypothesize that by applying this approach, higher local control and resection rates can be achieved (typically below 13% for patients who are initially deemed unresectable). Additionally, this treatment option is expected to help delay or reduce the need for (a switch in) systemic treatment and eventually improve survival in patients with liver metastases that are not resectable. All studies reporting the results of TARE at ablative doses are retrospective cohort studies or cases series. Prospective data is needed to expand the indications and reimbursement of radioembolization. Other objectives of the study are:
- To calculate the resection rate in patients undergoing the combined approach.
- To evaluate immune markers in peripheral blood and resected metastases.
- To formulate the first concept of an algorithm, enable to deliver personalized AI assisted dosimetry.
- To assess potential role of circulating tumor DNA (ctDNA) in evaluation of patient prognosis and follow up.
- To determine the grade of necrosis at the time of resection and correlate with the absorbed dose.

Interventions
Yttrium-90 microspheres are administered through the hepatic artery which supplies blood to tumor tissue (the portal vein supplies blood to the normal hepatic tissue). The microspheres are trapped in the vasculature of the tumor due to arteriolar capillary blockage where they exert a local radiotherapeutic effect. In clinical use, the glass microspheres remain permanently trapped in the vasculature where the isotope decays to infinity leaving background radiation with no therapeutic value. This procedure is combined with standard systemic therapy per routine clinical practice.
Eligibility Criteria
Patients (N = 30) with insufficient FLR and patients with unfavorable lesion location, size and/ or number, requiring downsizing of metastases in order to achieve R0 resection will be discussed at the respective local multidisciplinary teams (MDT) meetings. Patients can be included if they are found suitable for TARE and surgery based on a liver MRI, contrast enhanced CT or PET-CT and clinical and laboratory results. Patients are allowed to undergo other local liver treatments (e.g. ablation) in combination with TARE, as long as all liver metastasis are locally treated to achieve R0 resection. Patients are not allowed to use systemic chemotherapy two weeks prior and two weeks post TARE. Target therapies have to be stopped at least 4 weeks prior to TARE.
You may qualify if:
- Histologically confirmed primary adenocarcinoma of the colon or rectum
- Potentially resectable colorectal liver metastases, with limiting factors for resection including:
- Insufficient future liver remnant.
- Unfavorable tumor location (e.g. involvement of a major vessel and/or bile duct)/ large size and/ or number of lesions, which limit resection with R0 margins and requires downsizing of the metastases
- No or limited extrahepatic metastatic disease (limited extrahepatic disease should be amenable to eradicate with locoregional therapies as per multidisciplinary discussion of surgeons, radiation oncologists and interventional radiologists)
- Signed informed consent;
- Age ≥ 18 years;
- Eastern Cooperative Oncology Group (ECOG) performance status 0-1;
- Life expectancy of ≥ 3 months;
- Measurable target tumors in the liver according to RECIST 1.1
