[摘要] 目的 通过检测葡萄糖转运蛋白1(Glut1)在腹膜恶性间皮瘤、卵巢癌和反应性间皮细胞增生中的表达,探讨Glut1在腹膜恶性间皮瘤(PMM)病理诊断和鉴别诊断中的作用。 方法 采用免疫组织化学方法检测Glut1在各30例PMM、卵巢癌及反应性间皮细胞增生中的表达情况,分析Glut1在PMM病理诊断和鉴别诊断中的作用。结果 Glut1在PMM、卵巢癌、反应性间皮细胞增生中的阳性表达率分别为66.7%,93.3%和0。Glut1在PMM在与卵巢癌中的表达率差异有统计学意义(P<0.01)。在PMM与反应性间皮细胞增生中表达率差异亦有统计学意义(P<0.001)。结论 PMM与反应性间皮细胞增生鉴别诊断时,Glut1免疫标记有确切的鉴别诊断价值。在与卵巢癌进行鉴别诊断时,虽然两者阳性表达率均较高,但阳性表达强度明显不同,卵巢癌为强阳性表达。此时一同运用其他PMM阳性及阴性免疫标记物才更有诊断价值。

[Abstract] Objective To investigate the expression of glucose transporter 1(Glut1) in peritoneal malignant mesothelioma, ovarian cancer and reactive mesothelial cell hyperplasia, and to explore the role of Glut1 in the pathological diagnosis and differential diagnosis of peritoneal malignant mesothelioma (PMM). Methods Immunohistochemistry was used to detect the expression of Glut1 in 30 cases of PMM, ovarian cancer and reactive mesothelial cell proliferation. The role of Glut1 in pathological diagnosis and differential diagnosis of PMM was analyzed. Results The positive rates of Glut1 in PMM, ovarian cancer and reactive mesothelial cell proliferation were 66.7%, 93.3% and 0, respectively. There was a significant difference in the expression of Glut1 between PMM and ovarian cancer(P<0.01). The difference in expression rate between reactive mesothelial cells and proliferation was also statistically significant(P<0.001). Conclusion The differential diagnosis of Glut1 immunolabeling in the differential diagnosis of PMM and reactive mesothelial hyperplasia is of value. In the differential diagnosis with ovarian cancer, although the positive expression rate of both is high, the positive expression intensity is obviously different, and the ovarian cancer shows strongly positive expression. It is of more diagnostic value to use other PMM positive and negative immunological markers together.

腹膜惡性间皮瘤(peritoneal malignant mesothelioma,PMM)是一种腹膜原发性的高度恶性肿瘤,由于临床表现缺乏特异性,常被误诊为卵巢癌等疾病[1]。PMM在病理组织形态学上与同在盆腔的卵巢低分化癌以及反应性间皮细胞增生等良恶性病变都有类似之处,尤其是在穿刺组织活检诊断时鉴别诊断尤为困难,往往需要结合影像学资料、免疫组织化学以及分子生物学等方法进行综合判断才能确诊。关于Glut1在PMM中的表达及其诊断价值的研究,国外报道相对较多,国内报道较少。我们收集了30例,结合有关文献对Glut1在PMM病理诊断和鉴别诊断中的作用进行分析及探讨。
1 资料与方法
1.1 一般资料
收集余姚市人民医院2003~2015年期间临床病理确诊为PMM的30例患者的临床、蜡块等材料。患者全部为女性,年龄44~68岁,中位年龄54岁。病理学分型:上皮型24例,双相型6例。其中21例PMM患者在20~40年前有时间长短不一的石棉接触史;……
