三阴性乳腺癌因目前尚未找到有效的治疗靶点,当前治疗仍以化疗为主。就三阴性乳腺癌的辅助和新辅助化疗来说,蒽环类和紫杉类药物的联合或序贯治疗仍是当前的标准治疗,由于联合治疗的毒性大,目前临床多用蒽环类紫杉类的序贯方案。临床上三阴性乳腺癌优选的辅助新辅助方案包括了剂量密集用药(dose-dense)和紫杉醇的每周用药方案。另外,蒽环类紫杉类的用药顺序研究显示似乎紫杉类序贯到蒽环类更有优势(ESMO 2014:吉西他滨联合顺铂(GP)或紫杉醇(GT)一线治疗复发或转移性三阴性乳腺癌获良好疗效(CBCSG006试验) )(Lancet Oncology:“老药新用”治疗三阴性乳腺癌 )。

在早期三阴性乳腺癌中,对于铂类的应用,研究者也做了诸多的探索。最著名的两项新辅助研究GeparSixto 及CALGB 40603均证实了在蒽环类和紫杉醇基础上加用卡铂用于早期三阴性乳腺癌的新辅助治疗,可有效提高PCR。但研究者仍存在疑虑是否提高PCR代表了患者预后的改善,以及如何将铂类药物与标准方案联合等问题。因此,大多数专家观点还是认为,并不是所有三阴性乳腺癌患者均能从铂类治疗中获益,把铂类引入三阴性乳腺癌的标准新辅助和辅助治疗的时机尚不成熟。目前有较多证据表明,具有BRCA1突变的三阴性乳腺癌患者更有可能从铂类的治疗中获益。在今年St.Gallen国际乳腺癌会议上,对这一问题也进行投票发现,约半数以上的专家认为答案是肯定的,但仍存在意见分歧,尚有待更多的临床研究证实。

除此之处,关于卡培他滨和依沙匹隆的研究正在进行中,其最终结果也值得期待。

在三阴性乳腺癌的辅助和新辅助靶向治疗方面,虽然有一些药物在晚期乳腺癌中得到了较好的初步结果,但辅助和新辅助领域的结果仍在比较早期的探索中。如PARP抑制剂、贝伐珠单抗等针对VEGF的靶向药物、西妥昔单抗等针对EGFR的靶向药物,以及mTOR抑制剂等药物。目前尚未引入标准的辅助和新辅助治疗领域。

另外提得一提的是,三阴性乳腺癌具有不同的亚型。临床前研究结果提示,不同亚型对药物的敏感性不同。因此,分别找出适合不同亚型治疗的药物将是未来研究的热点。

PNAS:极难治乳腺癌觅良方?蛋白抑制剂为化疗开路

三阴乳腺癌是一类目前让广大医生头疼的肿瘤。“三阴乳腺癌”指雌激素受体(ER)、孕激素受体(PR)及人表皮生长因子受体2(HER-2)均阴性的乳腺癌患者。这类肿瘤细胞所缺乏三种蛋白质,正是乳腺癌常规治疗强有力的靶点。正因如此,医生只能使用传统的化疗药物对其进行治疗,而这些药物在三阴乳腺癌患者中的长期有效性仅有20%。现在,约翰霍普金斯大学的研究员们发现,乳腺癌细胞能够抵抗化疗的机制——他们已经找到一
