具有丙型肝炎病毒抗原标志的肝细胞癌的病理学特征

目的系统地分析具有不同肝炎病毒抗原标志的肝细胞癌（ＨＣＣ）的组织病理学特征。方法用免疫组化ＰＡＰ法、ＡＢＣ法显示６９例组织中ＨＢＶ及ＨＣＶ抗原，运用ＣＡＳ－２００系统对癌组织进行图像分析。结果与单独ＨＢＶ感染者相比，单独ＨＣＶ感染相关ＨＣＣ中透明细胞型肝癌发生率较高（７／９比４／３３），分化较好；癌周肝窦内和汇管区淋巴细胞浸润及肝细胞坏死较轻（Ｐ＜０．０１）；小胆管破坏较常见，且与淋巴滤泡样结构形成关系密切（Ｐ＜０．０５）。此外，该组患者年龄较大，临床症状较轻，手术预后较佳。结论单独ＨＣＶ感染相关ＨＣＣ具有不同于单独ＨＢＶ感染相关ＨＣＣ的临床及病理学特征，癌细胞核ＤＮＡ含量及形态学参数定量分析结果与其生物学行为相符。

Pathological features of hepatocellular carcinoma carrying hepatitis C virus antigen

OBJECTIVE: To analyze the pathological features of hepatocellular carcinomas (HCCs) carrying different hepatitis virus antigens histopathologically and systematically. METHODS: PAP and ABC kits were used in the immunohistochemical study, and CAS-200 System was applied in the image cytometry. RESULTS: As compared with HCCs carrying HBV marker(s), the HCCs carrying HCV marker showed more cases of clear cell type (7/9 vs 4/33), better differentiation of cancers, less necrosis of hepatocytes, milder lymphocyte infiltration in the hepatic sinuses or periportal areas (P < 0.01), higher incidence of bile ductule damages, and bore a close relation to the formation of lymphoid follicle in the surrounding tissues (P < 0.05). These patients were elder, with lower grade of symptoms and better prognosis after operation. CONCLUSION: HCCs carrying only HCAg have different pathological features and clinical characteristics from which carrying HBV marker(s). The results of image cytometry are in accordance with the biological behaviour of HCC.
