Clin Cancer Res:乳腺导管原位癌术前局部应用他莫昔芬凝胶同样有效

2014-07-28 MedSci MedSci原创

Clinical Cancer Research 7月15日在线发表的一项小型phase 2研究显示,与口服他莫昔芬相比,局部使用4-羟基他莫昔芬(4-OHT,他莫昔芬的抗雌激素代谢产物)凝胶制剂在乳腺导管原位癌(DCIS)术前应用,与口服他莫西芬同样有效,支持对这一局部外用治疗进行进一步研究(Clin. Cancer Res. 2014;20:3672-82)。这是一项随机、双盲、

Clinical Cancer Research 7月15日在线发表的一项小型phase 2研究显示,与口服他莫昔芬相比,局部使用4-羟基他莫昔芬(4-OHT,他莫昔芬的抗雌激素代谢产物)凝胶制剂在乳腺导管原位癌(DCIS)术前应用,与口服他莫西芬同样有效,支持对这一局部外用治疗进行进一步研究(Clin. Cancer Res. 2014;20:3672-82)。

这是一项随机、双盲、II期临床研究,由芝加哥西北大学Robert H. Lurie癌症中心的Oukseub Lee医生及其同事进行,入选26例绝经前和绝经后雌激素受体阳性DCIS女性患者,14例接受口服他莫昔芬治疗(20 mg/d),12例接受局部4-OHT凝胶制剂治疗(4 mg/d)。这些女性在诊断性核芯针活检后至手术切除前接受为期6周(中位数)治疗。结果显示,研究者对核芯针活检和手术切除的组织进行比较发现,两组患者乳腺组织中的癌细胞生长标志物(Ki-67)的降幅相似。两组患者乳腺中的4- OHT平均浓度也相似,但口服他莫昔芬组的平均血浆4-OHT浓度约为局部治疗组的5倍(1.1 ng/mL vs. 0.2 ng/mL)。在口服他莫昔芬组患者中检测到凝血相关蛋白增加,但在局部治疗组未观察到这一现象。两组的潮热发生率无差异。

另一名研究者——Lurie癌症中心乳腺癌项目联合主任Seema Khan医生表示,如果4-OHT凝胶制剂在样本量更大的研究中被证明有效,则可能代替口服他莫昔芬用于乳腺癌预防和DCIS,并促使更多的女性使用该凝胶制剂。该凝胶制剂可最大程度上减少身体其他地方暴露于药物,使药物集中于所需治疗的乳房上,这应可避免潜在血凝块的产生和子宫癌风险增加。
