Major impact of personalized dosimetry using 90Y loaded glass microspheres SIRT in HCC: Final overall survival analysis of a multicenter randomized phase II study (DOSISPHERE-01).

516 Background: 90Y loaded microsphere SIRT (radioembolization) is a treatment option in advanced HCC. However, no personalized dosimetric endpoints are currently used. The goal of this study was to compare the efficacy of 90Y loaded glass microsphere SIRT in HCC using a standard versus a personalized dosimetric approach. Methods: DOSISPHERE-01 was a multicenter, randomized phase 2 trial in unresectable HCC patients with at least one tumor ≥7cm....
