乳腺癌是女性发病率最高的恶性肿瘤,内分泌治疗是激素受体阳性乳腺癌的主要治疗手段,但约1/3患者存在原发耐药,而且几乎所有患者会出现继发耐药,因此内分泌耐药是乳腺癌治疗中亟待解决的重要问题。自2004年,张清媛等人在五项国家自然科学基金的支持下,对乳腺癌内分泌耐药机制进行深入系统的研究,证实了生长因子信号通路异常激活,肿瘤血管生成参与内分泌耐药,提出了雌激素解救内分泌耐药的最佳时机,研究了植物雌激素在内分泌治疗中的作用,包括:1.证实乳腺癌内分泌耐药时生长信号通路异常激活,进而激活AIB1导致TAM耐药,提出AIB1是乳腺癌内分泌耐药的新靶点;2.证实肿瘤血管生成参与耐药,TAM可通过ER结合VEGF基因启动子上游功能性ERE序列阻遏VEGF转录,人参皂甙Rg3及低剂量化疗可通过抑制血管生成延缓内分泌耐药;3.对于多线内分泌耐药的患者,可通过CTCs进行监测,提出FAS表达升高是雌激素解救内分泌耐药的最佳时机的观点;4.研究证实大豆植物雌激素与芳香化酶抑制剂联合应用不仅安全,还具有骨保护作用。通俗地讲,就是证实了乳腺癌患者进食豆制品是安全的,且具有减轻内分泌药物所致的骨关节症状。

有关专家认为,该研究为临床逆转和延缓耐药提出了切实可行的方法,大幅度提高了乳腺癌的内分泌药物治疗效果,为实现个体化治疗,建立合理的乳腺癌内分泌治疗模式奠定了理论和实践基础。据悉,有关该项研究已发表论文共53篇,其中SCI收录 36 篇,他引总次数 412 次,其中SCI他引次数 305 次。
