摘要
肝细胞癌(hepatocellular carcinoma,HCC)发病率居世界最常见癌症第5位、最常见癌症死亡原因第3位[1]。目前根治性治疗方法包括手术切除、肝移植和局部消融(热消融、无水乙醇消融等)。治疗HCC最有效的方法是外科手术切除或肝移植。然而只有20%-30%的患者能够获得切除的机会[2,3],供体肝的短缺又限制了肝移植的应用,事实上绝大部分的病人需要接受非手术治疗。1971年,Goldenberg等M。对人结肠癌小鼠皮下种植模型进行局部热消融,发现肿瘤被破坏后远处的转移灶缩小甚至消失,
Image-guided tumor thermal ablation plays a key role in the management of hepatocellular carcinoma.Thermal ablation for hepatic tumors not only generates directly killing effect on liver tumors,but also improves the level of anti-tumor immunity of the host.Thermal ablation potentially affects the anti-tumor immunity in the following ways:(1) causing necrosis that is a source for intracellular antigens,and also inducing local inflammation,which further stimulates the antigen-presenting cells;(2) removing the tumor burden;(3) undergoing the process of heat shock in surviving tissue,leading to increase in the expression of heat shock proteins;(4) activating and enhancing tumor-specific T-cell responses.This review discusses these possible mechanisms.
