Anticancer Res:根治性前列腺切除术仍会出现生化复发率

2015-01-04 MedSci MedSci原创

很早之前发现前列腺癌干细胞样细胞(肿瘤干细胞)/起始细胞(CICs)表达肝细胞生长因子(HGF)和HGF/c-MET原癌基因产物(c-MET)信号,具有维护前列腺肿瘤干细胞/起始细胞自分泌方式的作用。因此, HGF是前列腺肿瘤干细胞/起始细胞的标志。 我们假设HGF的高表达可能与前列腺癌根治性前列腺切除术后的早期复发相关,本研究的目的是评估HGF的表达在前列腺癌组织和根治性前列腺切除术后生化复发

很早之前发现前列腺癌干细胞样细胞(肿瘤干细胞)/起始细胞(CICs)表达肝细胞生长因子(HGF)和HGF/c-MET原癌基因产物(c-MET)信号,具有维护前列腺肿瘤干细胞/起始细胞自分泌方式的作用。因此, HGF是前列腺肿瘤干细胞/起始细胞的标志。

我们假设HGF的高表达可能与前列腺癌根治性前列腺切除术后的早期复发相关,本研究的目的是评估HGF的表达在前列腺癌组织和根治性前列腺切除术后生化复发率之间的关系。

101例从2008年11月到2011年10月接受打开或腹腔镜根治性前列腺切除术,具有适当的前列腺特异抗原(PSA)的前列腺癌患者,对其进行了随访调查。HGF的免疫组织化学染色特性与根治性前列腺切除术后生化复发进行对比。HGF阳性率为5%的或者更高的肿瘤患者表现出明显缩短的无生化复发期相比于HGF阳性率低于5%的肿瘤患者(p=0.001)。在多变量Cox回归分析,术前前列腺特异抗原和HGF阳性是前列腺切除术后生化复发的独立预测指标。

我们的发现HGF是前列腺肿瘤干细胞/起始细胞的标志,与前列腺癌患者根治性前列腺切除术后生化复发率有着直接联系。

吸烟可能增加前列腺癌致死风险

美国研究人员6月21日说,吸烟可能增加前列腺癌患者的死亡几率。   哈佛大学公共卫生学院教授斯泰茜·肯菲尔德及其同事1986年至2006年间随访5366名前列腺癌病人,研究结果由最新一期《美国医学会杂志》(JAMA)发表。   肯菲尔德告诉路透社记者:“与从不吸烟者相比,吸烟者患前列腺癌后的死亡几率要高出61%,前列腺癌治愈后复发的几率同样高61%。”
