CDK4/6抑制剂前途,乳腺癌免疫疗法值得期待

2019-12-06 佚名 肿瘤资讯

ABC共识囊括了逆转肿瘤耐药的药物以及更多用于进展期乳腺癌的治疗方法。目前临床面临很多挑战,即部分患者在治疗一段时间后,肿瘤会对临床治疗用药产生耐药。而研究发现一些新药能够逆转肿瘤耐药现象,增加进展期乳腺癌患者的缓解率、疾病控制时间以及总生存期。这告诉我们,理解疾病的生理进程和生物靶点是很重要的,这可以帮助我们改善对疾病的疗法,随着对乳腺癌的进一步了解,我相信未来这是一个可以治愈的疾病。

ESO-ESMO 晚期乳腺癌第 5 届国际共识大会 (ABC5)在葡萄牙里斯本举行,该会议专注晚期乳腺癌诊疗进展并每2年更新一次指南。本次会议期间,肿瘤资讯非常荣幸邀请到乳腺癌治疗领域的世界级专家、纪念斯隆·凯特琳癌症中心的Larry Norton教授分享ABC5共识与乳腺癌进展。

逆转肿瘤耐药,乳腺癌治愈可期

ABC共识囊括了逆转肿瘤耐药的药物以及更多用于进展期乳腺癌的治疗方法。目前临床面临很多挑战,即部分患者在治疗一段时间后,肿瘤会对临床治疗用药产生耐药。而研究发现一些新药能够逆转肿瘤耐药现象,增加进展期乳腺癌患者的缓解率、疾病控制时间以及总生存期。这告诉我们,理解疾病的生理进程和生物靶点是很重要的,这可以帮助我们改善对疾病的疗法,随着对乳腺癌的进一步了解,我相信未来这是一个可以治愈的疾病。

CDK4/6抑制剂在乳腺癌的治疗突破仅仅是个开始

已经有很多非常重要的研究证明CDK4/6抑制剂可以给患者带来获益,对各种类型的内分泌疗法敏感的HR+乳腺癌患者能够在缓解率,缓解时间和总生存期获得获益,改变了临床的标准疗法,但我相信对这类药物的了解仅是刚开始。越来越多的证据表明,CDK4/6抑制剂联合内分泌疗法及其它疗法的联合治疗,例如免疫疗法,可以产生更好的疗效,扩大了免疫响应范围。我认为接下来对它剂量以及治疗时间的研究会有更大突破,CDK4/6抑制剂未来的市场将更广阔。患者治疗方案的选择必须基于每位患者的耐受性和肿瘤生物学效应而优化选择,这可以增加这类药物的活性。CDK4/6抑制剂现在仅用于雌激素受体阳性的乳腺癌患者的治疗,但是我认为CDK4/6抑制剂的应用前景会更加广阔,在其他疾病和不同类别的患者中探寻它的治疗用途是非常值得期待的。

未来已来,免疫可期

我们可以看到,免疫检查点抑制剂治疗PD-L1阳性的三阴乳腺癌患者显示出部分疗效,疗效一般但确实是存在的,它确实对生存有影响,这点我们需要特别注意。TNBC反应率,无进展生存期获益一般,但患者总生存期显着获益引起注意,因为这证明免疫检查点抑制剂的治疗可以抑制新的转移性疾病的发展,现在的临床研究已经开始将肿瘤缩小率和对现有肿瘤的控制率作为临床终点,控制肿瘤的新转移对于临床治疗来说是非常重要的。由于过去在临床中太难测定,我们并没有给予这点太多关注,免疫疗法现在主要有免疫检查点抑制剂,但是越来越多新类型的免疫疗法慢慢出现,它们与现有疗法的联合会在控制新的癌症转移上带来更广的获益。
