Brief summary

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.

Interventions

RADIATIONY90 TARE

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.

DIAGNOSTIC_TESTPET/CT

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.
