SABCS:乳腺癌预后指标的意外之喜—维生素D

2012-12-13 SABCS SABCS

       在第35届圣安东尼奥乳腺癌会议(SABCS)上发布的研究生物标志物的AZURE试验的初步结果显示:在标准治疗基础上联合使用唑来膦酸的乳腺癌患者,如果体内维他命水平不足,其预后劣于维他命D处于正常水平的患者。该研究的作者是英国谢菲尔德大学的Robert Coleman医学博士,他指出:“乳腺癌女性患者体内维生素D水平正常时往往显示较好的预后。我们

       在第35届圣安东尼奥乳腺癌会议(SABCS)上发布的研究生物标志物的AZURE试验的初步结果显示:在标准治疗基础上联合使用唑来膦酸的乳腺癌患者,如果体内维他命水平不足,其预后劣于维他命D处于正常水平的患者。该研究的作者是英国谢菲尔德大学的Robert Coleman医学博士,他指出:“乳腺癌女性患者体内维生素D水平正常时往往显示较好的预后。我们应当检测患者体内的维生素D水平,并适时给予补充,但是我还不确定维生素D是否可作为改变患者结局的措施。”

       Coleman的研究小组去年在的《新英格兰医学杂志》上发表了AZURE试验( N Engl J Med. 2011;365:1396-1405)的研究结果,这一研究入组了II期或III期的乳腺癌患者共3360名,比较了标准全身用药和在此基础上联合唑来膦酸4mg两种方案的疗效。唑来膦酸可减少或延缓发生骨转移的癌症患者的骨骼并发症。

       Coleman报告称:在中位随访53.3个月后,研究人员发现,两个治疗组的无病生存期初步分析结果没有差异(唑来膦酸的危害比[HR]为1.15),但是亚组分析显示:绝经后妇女从唑来膦酸治疗中显著获益(唑来膦酸的危害比[HR]为0.75)。

       研究人员对患者体内的生物标志物进行了分析,Coleman博士解释:“我们觉得应该去了解乳腺癌的某些生物学因素,或许可以解释这个意外的结果。”

       研究人员对初始研究中的872名患者检测了25-羟基维生素D血清水平、Ⅰ型前胶原氨基端前肽(PINP,骨形成标记物)和β-Ⅰ型胶原羧基端肽(β-CTx,骨吸收标记物)水平,分析它们是否与结果相关。PINP>70ng/mL和β-CTx<0.299 ng/mL时为异常,维生素D<30ng/mL时即意味着缺乏。

       入组的872例乳腺癌患者中,近半数(46.9%)患者尚未绝经,30.5%的患者绝经时间超过5年,14.1%患者绝经时间不足5年。

       分析发现,PINP和β-CTx的水平均与患者的预后无关,但是对于维生素D,却有着出人意料的发现。尤其是在PINP水平异常和正常的患者中,乳腺癌骨转移的发生时间(HR,1.15; P=0.5957)和远处复发转移时间(HR,0.86; P =0.4098)均无显著差异。  β-CTx分析也显示了相似的结果,β-CTx水平正常和异常的患者发生骨转移(HR,1.43; P=0.592)和远处转移(HR,1.21; P =0.2559)的时间相似。

       Coleman博士总结说:“PINP在预测乳腺癌患者骨转移或者远处转移方面没有任何价值。虽然目前的研究有高水平的CTx导致较差预后的趋势,但是在预测骨转移或远处转移上没有统计学意义。”

       相反,血清中足量的维生素D水平预示了较低的骨转移复发的风险(HR, 0.11; P=0.0257),并显示了改善患者远处转移复发预后的趋势(HR,0.56; 95%CI,0.31; P=0.0519)。

       绝经后的乳腺癌患者中,维生素D水平高的患者(HR,0.09)从唑来膦酸治疗中的获益显著优于维生素D缺乏的患者(HR,0.72),这种差别具有统计学意义(P=0.0747)。绝经前乳腺癌患者对唑来膦酸治疗反应略差,血清中维生素D充足(HR, 1.45)或缺乏(HR, 1.44)对其没有影响(P=0.9886)。

       尽管该研究中维生素D水平的影响很明显,但是洛杉矶生物医学研究所的Rowan Chlebowski博士在会后表示, 该结果是否能作为补充维生素D的信号还不清楚。美国妇女健康倡议(WHI)和其他的研究显示维生素D水平的个体差异只有20%可以归因于饮食、补充剂、日晒、运动和身体质量指数(BMI)。其他80%的个体差异是由基因决定的,除了佝偻病,没有任何补充维生素D的干预显示改善疾病结局的。因此,我们应该以谨慎的态度分析该研究结果的临床意义
