Selective effects of Lipiodolized antitumor agents

Area of Science:

• Oncology
• Radiology
• Pharmaceutical Sciences

Background:

• Lipiodol Ultra-Fluid (Lipiodol) demonstrates prolonged tumor retention via arterial delivery.
• Hydrophilic chemotherapy agents face solubility challenges with oil-based Lipiodol.

Purpose of the Study:

• To introduce and evaluate a novel "Lipiodolization" technique for delivering water-soluble anticancer drugs.
• To assess the efficacy of the Lipiodol-Urografin-chemotherapy system in treating hepatocellular carcinoma.

Main Methods:

• Lipiodolization: water-soluble agents were prepared using Urografin as an intermediate.
• Treatment involved intra-arterial administration of the Lipiodol-Urografin-chemotherapy system.
• Patient outcomes were assessed via serum alpha-fetoprotein (AFP) levels, tumor imaging, and histologic analysis.

Main Results:

• The Lipiodol-Urografin system containing antitumor agents was administered to 13 primary hepatocellular carcinoma patients.
• Significant reductions in serum AFP levels and tumor size were observed.
• Histologic examination of resected specimens supported treatment efficacy.

Conclusions:

• The Lipiodolization technique is effective in delivering water-soluble anticancer agents selectively to tumors.
• This innovative approach demonstrated a 77% efficacy rate in treating hepatocellular carcinoma.
• Lipiodolization represents a promising new strategy for selective cancer chemotherapy.
