叶酸结合蛋白可作为卵巢恶性肿瘤早期诊断标志物

2012-05-21 鲍爱宁摘编 医学论坛网

  最近,广西医科大学附属肿瘤医院妇瘤科基础实验部的研究人员的一项研究显示,叶酸结合蛋白(folate binding protein,FOLR1)可作为一种新型的卵巢恶性肿瘤早期诊断标志物,并可成为判断卵巢恶性肿瘤多药耐药潜在标志之一。该研究发表于2012年第1期《中国癌症杂志》。   该研究旨在探讨卵巢恶性肿瘤组织中FOLR1的表达及其临床意义。   黄明钜等研究人员采

  最近,广西医科大学附属肿瘤医院妇瘤科基础实验部的研究人员的一项研究显示,叶酸结合蛋白(folate binding protein,FOLR1)可作为一种新型的卵巢恶性肿瘤早期诊断标志物,并可成为判断卵巢恶性肿瘤多药耐药潜在标志之一。该研究发表于2012年第1期《中国癌症杂志》。

  该研究旨在探讨卵巢恶性肿瘤组织中FOLR1的表达及其临床意义。

  黄明钜等研究人员采用Western blot检测80例卵巢恶性肿瘤组织、50例卵巢良性肿瘤组织及30例正常卵巢组织中的FOLR1表达情况,分析其与卵巢恶性肿瘤临床病理及多药耐药的相关性。

  结果显示,FOLR1在正常卵巢组织、卵巢良性肿瘤组织和卵巢恶性肿瘤组织中的表达量依次增高(P<0.01)。FOLR1在卵巢恶性肿瘤临床分期中Ⅰ~Ⅱ期的表达量低于Ⅲ~Ⅳ期(P<0.05)。FOLR1在铂类药物耐药型卵巢恶性肿瘤中的表达量低于铂类药物敏感型(P<0.01);治疗后肿瘤进展者的表达量低于缓解者(P<0.01)。FOLR1在黏液性肿瘤中的表达量低于浆液性肿瘤(P<0.05),恶性卵巢肿瘤有淋巴结和远处器官转移的高于无转移者(P<0.05),其表达量与患者的不同肿瘤病理分类、是否有大网膜转移和腹水量无明显相关(P>0.05)。取FOLR1表达量界值为3.115时来判断卵巢肿瘤性质,ROC曲线的Youden指数最大,卵巢恶性肿瘤FOLR1表达量的高低与中位生存时间长短差异无明显相关(P>0.05),Cox模型多因素分析显示,FOLR1表达量不是影响患者生存预后的独立因素。

卵巢巨大肿瘤一例

      患者女性,18岁,因“右季肋部不规则疼痛”到急诊室就诊。临床检查发现,腹部右侧可及一较大肿块。经阴道超声(TVUS)检查发现一较大的无回声、多房性病变(大小16×12×15 cm,可见5个以上的腔室),分隔隔膜厚度<3mm且肿瘤血管颜色评分为1分(基于国际卵巢肿瘤分析组标准),肿瘤起源于右侧卵巢。CT扫描(见图1)证实了上述超声检查结果
