肝癌动脉化疗栓塞效果的病理评价

目的研究肝细胞癌经动脉化疗栓塞治疗后癌肿的变化，探索提高疗效的方法。方法对动脉化疗栓塞治疗后行手术的３９例肝癌和１１例对照标本进行坏死程度与包膜、治疗次数、病理类型、分化、血管损伤及淋巴细胞浸润诸因素相关性的分析。结果完全坏死者６例，３０％＿９５％坏死者１４例，仅５％坏死及无坏死者１９例，１１例ＤＳＡ无坏死。癌肿坏死程度与肿癌分化、治疗次数、淋巴细胞浸润无关，而与病理类型、包膜、血管损伤有关。结论肝癌动脉化疗栓塞是中晚期肝癌目前唯一可取的治疗方法。对于有包膜的肝细胞癌，只要治疗能达到癌肿部位，即使一次治疗，也可收到明显的效果。对于如何使每例都达到彻底的癌肿坏死是值得进一步探讨的。

Histopathological study of hepatocellular carcinoma after transcatheter hepatic arterial embolization

AIMS To study the histopathological changes in hepatocellular carcinoma (HCC) after transcatheter arterial embolization (TAE). METHODS Histopathological analysis was made in 39 cases of liver neoplasms after TAE and 11 cases of liver neoplasms after digital selective angiography (DSA), including pathological type, histological grade, necrotic degree, capsule, times of treatment, injured vessel and lymphocyte infiltration. RESULTS Six cases with 100% necrosis, 14 cases with 30% 95% necrosis, 19 cases with 0% 5% necrosis after TAE and 11 cases without necrosis after DSA were found histologically. The necrosis was related to the pathological type, capsule, injured vessels, but not to the histological grade, time of treatment and lymphocyte infiltration of the liver neoplasms. CONCLUSIONS TAE is an effective therapy for the late stage HCC. The encapsulated HCC is a preferable indicator for TAE.
