Treatment of Intermediate-stage Hepatocellular Carcinoma

The purpose of this study is to evaluate the efficacy and safety of transarterial chemoembolization (TACE) combined with arginine hydrochloride and trimetazidine hydrochloride tablets in the treatment of patients with hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is the sixth most common cancer and the second leading cause of cancer-related deaths in the world. Because HCC is insidious and early diagnosis is difficult, most patients have locally advanced or distant metastasis at the time of diagnosis. So they are not suitable candidates for curative treatments by resection or transplantation. Currently, Sorafenib is the only choice approved by FDA for advanced HCC, although it prolongs the survival for less than 3 months. Transarterial chemoembolization (TACE) is an important method of minimally invasive therapy in the comprehensive treatment of liver cancer. As a kind of combined treatment, it can obviously prolong the survival time of the patients. Recently, metabolomics studies of HCC have shown that typical Warburg effect was observed in hepatoma carcinoma cells. Arginine hydrochloride is a new anticancer drug in the treatment of liver cancer, which is mainly aimed at the pathway of energy metabolism. Trimetazidine hydrochloride may play an anti-tumor role by inhibiting fatty acid oxidation. The investigators have been proceeding this trial to evaluate the efficacy and safety of transarterial chemoembolization (TACE) combined with arginine hydrochloride and trimetazidine hydrochloride tablets in the treatment of patients with hepatocellular carcinoma.
