摘要篇首： The most common interventional therapies for liver cancer at present include transcatheter hepatic arterial chemoembolization (TACE),1 percutaneous ethanol injection2 and radiofrequency ablation,3 but all these therapies have some intrinsic disadvantages. Since the advent of electrochemo- therapy (EChT), it has been accepted as a safe and effective therapy for malignant tumors4,5 There are only a few experimental studies reporting the use of EChT in the treatment of liver cancer in the foreign medical literature.6-8 However, there have been some clinical studies, and even fewer reports of experimental studies on EChT for liver cancer in China. We used a rat implanted liver cancer animal model to monitor changes in tumour size, tumour necrosis, cellular apoptosis, expression of peripheral immunological markers (IL-2, sIL-2R, IL-6 and TNF-α) and survival.
