BJC:HER2/Ki-67阳性乳腺癌保乳术后局部复发风险较高

2012-02-27 MedSci MedSci原创

 《英国癌症杂志》(British Journal of Cancer)近期发表的一项研究表明,HER2/neu阳性/Ki-67阳性乳腺原位导管癌(DCIS)女性患者保乳手术后局部复发风险较高。   该研究共纳入了1982~2000年接受乳腺癌保乳术治疗的213例DCIS患者,其中141例仅接受保乳手术,72例同时接受了术后放疗。   研究采用免疫组化法对DCIS

 《英国癌症杂志》(British Journal of Cancer)近期发表的一项研究表明,HER2/neu阳性/Ki-67阳性乳腺原位导管癌(DCIS)女性患者保乳手术后局部复发风险较高。

  该研究共纳入了1982~2000年接受乳腺癌保乳术治疗的213例DCIS患者,其中141例仅接受保乳手术,72例同时接受了术后放疗。

  研究采用免疫组化法对DCIS组织的9种生物标志物(雌激素受体、孕激素受体、Ki-67、p53、p21、细胞周期蛋白D1、HER2/neu、钙粒蛋白和psoriasin)进行检测,并评估其与肿瘤复发的关联。

  结果显示,仅接受保乳手术治疗者和接受保乳手术+放疗者10年复发率分别为36%和18%。HER2/neu阳性/Ki-67阳性与DCIS局部复发风险升高显著相关,但与肿瘤分级和患者年龄无关。但上述9种生物标志物对侵袭性复发均无预测价值。
