Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to study the way radioembolization works by collecting biopsy samples of participants' tumors after the procedure. This research may improve the way that radioembolization is performed, which could help people whose cancer has spread to the liver. The research may also provide information about how tumors respond to radioembolization.

Study Groups

Participants with colorectal cancer liver metastases

The study population is represented by patients with colorectal cancer liver metastases that have been deemed clinically appropriate/eligible to receive Y90 TARE for the management of their liver metastases.

Y90 TARE

Intervention Type RADIATION

Y90 TARE will be performed as standard of care (SOC)/clinically indicated: 1) in a lobar or sub-lobar fashion (depending on tumor involvement and location; also targeting the tumor as selective as possible and sparing as much as possible of non-involved liver parenchyma), for participants with extensive bilobar disease or 2) in a radiation segmentectomy approach, intending to deliver 190 Gy radiation dose to target tumor: for patients with limited liver metastatic disease, not amenable for surgery or ablation.

PET/CT

Intervention Type DIAGNOSTIC_TEST

Following 90Y TARE, participants will receive a PET/CT or PET/MRI scan to measure the dose administered to the target tumor(s) and uninvolved hepatic parenchyma.

PET/MRI

Intervention Type DIAGNOSTIC_TEST

Following 90Y TARE, participants will receive a PET/CT or PET/MRI scan to measure the dose administered to the target tumor(s) and uninvolved hepatic parenchyma.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* age ≥ 18 years
* Eastern Cooperative Oncology Group (ECOG) performance status 0-2
* histologically confirmed primary adenocarcinoma of the colon or rectum
* CLM considered unresectable or not amenable to percutaneous ablation
* existent tissue samples from a standard of care biopsy of the target tumor within 42 days prior to treatment OR clinical indication for biopsy at the time of the treatment under the institutional guidelines for progression of disease.
* adequate blood cell counts (WBC \> 1.5 x 109/L, platelet count \> 50 x 109/L)
* adequate renal function (creatinine \< 1.5 mg/dL)
* total bilirubin level ≤ 1.5 mg/dL


A. patients not amenable to surgery or thermal ablation

Exclusion Criteria

* prior hepatic radiotherapy (The lesion / lobe being treated cannot have had prior treatment with radiotherapy - untreated lesions / lobes in the liver may be evaluated under the protocol)
* severe cirrhosis
* severe portal hypertension
* uncorrectable flow to the gastrointestinal tract and/or \>30 Gy (or \>50 Gy in multiple sessions) radiation absorbed dose to the lungs

All patients with liver-dominant disease will be considered candidates for TARE even in the face of oligometastatic (up to 5 sites) extrahepatic disease, that is stable or controlled by chemotherapy.
