摘要: 摘要: 目的 探究弥漫型肝细胞癌 (D-HCC) 的肿瘤克隆起源方式及其行肝移植治疗的预后。方法 选取 2004 年 8 月—2012 年 11 月天津市第一中心医院肝移植治疗的 14 例 D-HCC 患者, 收集患者一般资料及术后无瘤生存资料。选取 12 个高频肝癌微卫星杂合性缺失(LOH)位点, 通过聚合酶链反应-单链构象多态性(PCR-SSCP)评估 D-HCC 的肿瘤克隆起源方式。结果 14 例 D-HCC 患者中, 有 11 例单中心克隆起源(IM), 3 例单中心伴多中心克隆起源 (IM+MO)。术后无瘤生存时间为 4.5~37.4 个月, 无瘤生存中位时间为 8.7 个月。结论 D-HCC 的肿瘤克隆起源方式以 IM 为主, 肝移植可能是较为有效的治疗手段。

Abstract: Abstract: Objective To determine the tumor clonal origin of diffuse hepatocellular carcinoma (D-HCC) and clinical outcome after liver transplantation. Methods Fourteen D-HCC patients who underwent liver transplantation in the Tianjin First Central Hospital between August 2004 to November 2012 were evaluated retrospectively. Their clinical characteristics and data of disease-free survival postoperatively were gathered. Twelve loss of heterozygosity sites (LOH) on high frequency microsatellite were selected. The tumor clonal origin of D-HCC was assessed by the means of PCR-SSCP. Results Of 14 D-HCC patients, intrahepatic metastasis (IM) occurred in 11 cases (11/14), and IM with multicentric occurrence (MO) oc⁃ curred in 3 cases (3/14). The disease-free survival time was 4.5 to 37.4 months, and the median time was 8.7 months. Con⁃ clusion The most frequent tumor clonal origin of D-HCC was IM. Liver transplantation may be the effective treatment for D-HCC.
