简要总结
The purpose of this observational study is to evaluate properties of lipiodol-idarubicin emulsion mixed with the best regimen obtained in vitro study, including stability, viscosity，visibility under X-ray and deposition, in order to maximize the efficacy of idarubicin-cTACE for HCC.
详细描述
Idarubicin is a DNA topoisomerase II inhibitor that promotes DNA strand breakage, trapping cells in the G2 phase of the cell cycle and inducing DNA cleavage and cell apoptosis. Preclinical studies have shown that idarubicin has higher antitumor activity than epirubicin, especially against SUN-449 human hepatoma cells.
In recent years, foreign scholars have conducted a series of explorations in the treatment of hepatocellular carcinoma with lipiodol-idarubicin emulsion, and have obtained positive results.
However, in China, idarbicin has just been applied to TACE.Many interventional physicians are accustomed to directly use contrast agents to dissolve anthracyclines in order to improve tracer performance of chemotherapeutic agent-lipiodol emulsion under X-ray and reduce intraoperative reflux and misembolization. Meanwhile, due to the high density of the nonionic contrast media, the lipiodol emulsion can be deposited in the lesion for a long time. The Clinical Practice Guidelines for transcatheter arterial chemoembolization (TACE) Treatment of hepatocellular carcinoma in China (2021 edition) also recommended to prepare the chemotherapeutic drug-lipiodol emulsion according to the standard of " dissolving drug in nonionic contrast agent then mixed with lipiodol to make an emulsion with a ratio of 1:2".
At present, there is a lack of detailed objective data on the complete physical properties of the lipiodol-idarubicin emulsion, and some physicians and centers even make the emulsion based only on their habits and preferences.These all may affect the physical properties of the lipiodol emulsion, including intraoperative stability and viscosity of the emulsion, then eventually affect the operation of surgeon and the release behavior of chemotherapeutic drugs, and ultimately influence the efficacy of TACE.Therefore, the purpose of this prospective, observational study is to evaluate properties of lipiodol-idarubicin emulsion mixed with the best regimen obtained in vitro study, including stability, viscosity，visibility under X-ray and deposition, in order to maximize the efficacy of idarubicin-cTACE for HCC.
