摘要

非甾体抗雌激素他莫昔芬已成为一种高效、无毒的内分泌疗法,用于治疗IV期和II期雌激素受体阳性乳腺癌。他莫昔芬似乎是通过在目标组织水平上阻断内源性雌激素的作用而不是通过抑制循环雌激素水平来起作用的。在113例连续的IV期乳腺癌患者中,他莫西芬诱导50%的患者客观缓解,平均持续21个月以上,中位时间为16个月。这些结果与既往垂体切除术的结果相当。最近的随机研究比较了绝经后乳腺癌患者中雌激素和他莫西芬的药理剂量,显示这两种治疗方式的结果相当。抗雌激素治疗已被证明是有效的一些患者之前的内分泌添加剂治疗,特别是在消融手术后,如卵巢切除术,肾上腺切除术和垂体切除术。研究表明,在切除这些内分泌腺后,循环中的雌激素并没有完全消除,这可能是抗雌激素在这种情况下有效的原因。其他内分泌疗法已被证明是有效的之前治疗抗雌激素。垂体切除术可使60%最初对他莫西芬有反应的患者缓解,25%最初对他莫西芬无反应的患者缓解。最近的研究表明,氨基羟色胺加氢化可的松也可以诱导一些患者在先前用他莫西芬治疗后缓解。 This latter finding is of particular interest since aminoglutethimide is thought to work by blocking estrogen production, and the finding suggests that tamoxifen does not completely block all endogenous estrogen activity. Fluoxymesterone has been shown to induce remissions after tamoxifen or after tamoxifen plus hypophysectomy, and there was no correlation between the response to antiestrogen abd subsequent response to androgen. Because of its effectiveness and minimal side effects, tamoxifen is considered to be an initial endocrine therapy of choice in women with breast cancer. However, it has its limitations, as demonstrated by the results of secondary endocrine therapies such as hypophysectomy, medical adrenalectomy, and androgen therapy.
