Polyethylene Glycol Drug-Eluting Embolic Microspheres Loaded with Doxorubicin for the Treatment of Hepatocellular Carcinoma: Feasibility, Safety, and Pharmacokinetic Study.

Purpose: Polyethylene glycol drug-eluting microspheres (PEG-DEMs) can be loaded to elute doxorubicin. The current study evaluated the pharmacokinetic profile and safety of PEG-DEMs in the treatment of patients with hepatocellular carcinoma (HCC).

Materials And Methods: The current prospective, multicenter, dose-escalation study enrolled 25 patients (68% men) with early or intermediate stage HCC and a performance status of 0.

Transarterial Chemoembolization of HCC with Radiopaque Microspheres: Evaluation with Computed Tomography and the Complementary Role of Contrast-Enhanced Ultrasonography.

Purpose: To assess the diagnostic performance of computed tomography (CT), and of the combination of CT with contrast-enhanced ultrasonography (CT + CEUS), for the early evaluation of local response of hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE) with radiopaque drug-eluting microspheres (RO-DEMs).

Materials And Methods: 30 HCC patients (55 target tumors) were treated with TACE with RO-DEMs (diameter: 70-150 μm) preloaded with 75 mg doxorubicin/2 ml of microspheres. Unenhanced and contrast-enhanced CT, followed by CEUS, were performed 1-3 days post-RO-DEMs-TACE.

Pharmacokinetics, Safety, and Efficacy of Chemoembolization with Doxorubicin-Loaded Tightly Calibrated Small Microspheres in Patients with Hepatocellular Carcinoma.

Purpose: This study examines safety, efficacy, and pharmacokinetics of chemoembolization with loadable microspheres ≤100 μm for hepatocellular carcinoma.

Materials And Methods: A pilot safety study was performed in 19 patients with size and dose escalation and then 52 patients were enrolled prospectively and randomly assigned to chemoembolization with TANDEM™ loaded with 150 or 100 mg of doxorubicin.

Results: The mean diameter of the tumors was 7.
