[WCLC中国专场]徐建青教授解读免疫治疗,细胞免疫治疗有望缓解晚期肺癌疾病进展

2017-10-18 佚名 ioncology

过去十年,肿瘤免疫治疗是一个非常热门的领域,肿瘤免疫治疗的不同阶段进展将免疫治疗一步一步的推向热门的高潮。2013年SCIENCE杂志在总结2012年的科学领域的十大突破的时候把肿瘤免疫治疗列为第一位。近年来,CAR-T技术的兴起再一次掀起免疫治疗探究的狂潮,在血液肿瘤领域取得了非常卓越的疗效,然而在实体瘤领域的应用还是遇到了一些瓶颈。

过去十年,肿瘤免疫治疗是一个非常热门的领域,肿瘤免疫治疗的不同阶段进展将免疫治疗一步一步的推向热门的高潮。2013年SCIENCE杂志在总结2012年的科学领域的十大突破的时候把肿瘤免疫治疗列为第一位。近年来,CAR-T技术的兴起再一次掀起免疫治疗探究的狂潮,在血液肿瘤领域取得了非常卓越的疗效,然而在实体瘤领域的应用还是遇到了一些瓶颈。

在今年的WCLC上,来自上海市(复旦大学附属)公共卫生临床中心、复旦大学生物医学研究院的徐建青教授在中国专场上汇报了基于PD-1+CD8+ T和iNKT的免疫治疗在肺癌领域中的应用,通过体外刺激扩增PD-1+CD8+ T与iNKT细胞,并回输到患者体内,可以大大提高经各线治疗失败的晚期肺癌患者的病灶缓解情况。同时徐教授还介绍了临床治疗的病例资料,引起全场与会专家的关注。

从他们目前的研究数据来看,利用PD-1+CD8+ T和iNKT细胞疗法治疗晚期肺癌有望控制病灶的发展,且安全性良好,在已经治疗3个疗程以上的6例IV期肺癌患者中,有4例患者得到控制,2例肿瘤缩小,说明该方法值得进一步深入研究。另外,将这种细胞免疫治疗和其他疗法的结合将来也有望进一步提高患者的疗效。

徐建青教授专访内容:

过去十余年,肿瘤免疫治疗是一个非常热门的领域,肿瘤免疫治疗的不同阶段进展将免疫治疗一步一步地推向热门的高潮,主要表现在:其一、几项标志性的技术在临床中得到应用并获得有效性数据,其中最具标志性的是PD-1抗体在临床上应用获得近30%左右的有效率,2012年5-6月份新英格兰杂志上发表数据之后免疫治疗领域热度大增;其二、2013年SCIENCE杂志在总结2012年科学领域的十大突破的时候把肿瘤免疫治疗列为第一位,使免疫治疗领域热上加热;其三,在血液肿瘤领域,CAR-T技术治疗的有效率非常卓越,进一步加热了免疫治疗领域。

但是,CAR-T技术治疗在实体瘤领域还是遇到了一些技术上的瓶颈,免疫治疗在实体瘤领域的进一步推进困难重重。在我们团队考虑的计划中,实体肿瘤的免疫治疗可以分两步走:第一步,利用自体的具有抗肿瘤作用的免疫细胞进行免疫治疗,比如PD-1+CD8+ T与iNKT细胞联合进行肿瘤的免疫治疗。过去三年多已在临床进行了测试,其中针对肺癌领域的免疫治疗应用的研究例数相对较多,其它肿瘤还包括胰头癌、胃癌、食管癌、胸腺癌以及肾癌等也进行了尝试应用,总体来说该技术治疗的整体有效性比较乐观;此外,该技术可以通过和其它技术进一步结合来提升免疫治疗疗效。例如和放疗联合、PD-1抗体和溶瘤病毒联合等。第二步,研发更有效的、针对实体瘤的CAR-T技术。我们团队也在CAR-T领域开展了一些新技术的研发,未来有望进一步提升针对晚期肺癌的治疗疗效。本次大会我们将过去三年多时间利用PD-1+CD8+ T与iNKT细胞联合免疫治疗在肺癌领域应用的成果数据进行了报告。

大会设立了中国专场,主要有几方面的体会:第一、会场人满为患,规模空前盛大;第二,中国专场国内学者总体的报告水平都比较高、领域也比较广泛,无论是实体瘤的免疫治疗、实体瘤治疗疗效预测的靶标以及液体活检等领域相关报告都体现了国内肿瘤领域尤其是肺癌领域学者的治疗水平。例如,今天中国专场上国内专家对PD-1抗体、PD-L1抗体的临床研究情况进行了总结,包含了国内公司自主研发技术在临床上的应用成果,使参会学者获益匪浅,体现了目前中国在创新医学方面的成就,令人印象深刻。
