Drug-eluting bead transarterial chemoembolization with medium-sized versus small-sized CalliSpheres microspheres in unresectable primary liver cancer.

Purpose: The optimal microparticle size for drug-eluting beads transarterial chemoembolization (DEB-TACE) remains unknown. This retrospective cohort study analyzed the efficacy and safety of CalliSpheres microsphere embolization in the treatment of unresectable hepatocellular carcinoma (HCC) to determine the influence of particle size on the results.

Patients And Methods: Forty-two patients with unresectable HCC were enrolled in this retrospective study from January 2018 to January 2020.
