FTD-TPI, Bevacizumab, and Radioembolization With 166Ho-microspheres in Refractory Metastatic Colorectal Cancer

"Systemic treatment (FTD-TPI and bevacizumab) administration is according to standard clinical practice. Each treatment cycle will be 28 days in duration.~One treatment cycle consists of the following:~* Days 1-5: oral intake of FTD-TPI and bevacizumab IV infusion on day 1~* Days 8-12: oral intake of FTD-TPI~* Day 15: bevacizumab IV infusion~Bevacizumab 5.0mg/kg i.v. is repeated every 2 weeks.

"Individualized 166Ho radioembolization will be performed via a catheter during angiography. Before the treatment, a scout procedure will be performed to determine individualized 166Ho dose of the treatment. Dosimetry-based treatment planning will be individualized using Q- Suite software.~In case of bilateral disease, patients will be treated in two procedures to each hemi-liver, separated by 1 month. Before the first procedure, a scout procedure will be performed in which the individualized 166Ho dose of the first and second procedure will be calculated."
