CLIN CANCER RES:口服二磷酸盐可以改善乳腺癌患者预后

2017-04-05 MedSci MedSci原创

二磷酸盐通常用来治疗或预防骨质疏松。全世界有数百万人服用,其中绝大多数为绝经后女性。口服二磷酸盐与乳腺癌发病风险降低有关,而且三代二磷酸盐已被证实可以有效地治疗乳腺癌患者骨转移。口服二磷酸盐是否对乳腺癌患者预后产生影响尚缺乏证据。

二磷酸盐通常用来治疗或预防骨质疏松。全世界有数百万人服用,其中绝大多数为绝经后女性。口服二磷酸盐与乳腺癌发病风险降低有关,而且三代二磷酸盐已被证实可以有效地治疗乳腺癌患者骨转移。口服二磷酸盐是否对乳腺癌患者预后产生影响尚缺乏证据。

CLIN CANCER RES近期报道了一篇文章,研究口服二磷酸盐与乳腺癌患者预后的关系。纳入绝经后新发乳腺癌的女性患者,在诊断前未服用过二磷酸盐。研究共纳入3731例绝经后女性乳腺癌患者,平均随访时间70个月。在生存的患者中,乳腺癌诊断后服用二磷酸盐超过18个月的患者显着多于死亡对照组。调整了肿瘤分级、分期后,总生存OR值为0.63,P=0.03,乳腺特异性生存OR值为0.28,P=0.035.

文章最后得出结论,绝经后可能出现骨质疏松的女性确诊乳腺癌后口服二磷酸盐可以显着改善患者总生存以及乳腺特异性生存情况。这项发现对于低收入国家的乳腺癌患者有着尤为重要的意义。对于那些无法获得常规较昂贵治疗的贫困乳腺癌患者,口服二磷酸盐治疗为其提供了一个可以挽救生命新选择。
