虚实“组合拳”!中、荷科学家合作创制,肝癌精准治疗造福患者

记者3日获悉,上海交通大学医学院附属仁济医院上海市肿瘤研究所(下称:上海市肿瘤研究所)与荷兰癌症研究所合作研究创新制定了肝癌治疗精准策略。科学家们利用肝癌细胞的自身特点,如相关基因突变,先将肝癌细胞诱导进入细胞衰老状态,再特异清除肝癌细胞,这样的治疗模式对人体正常生长细胞并无影响。这种组合拳式或分步式(“One-twopunch”)治疗,可避免患者接受化疗,因严重毒副作用而受苦的现状。上海市肿瘤研

记者3日获悉,上海交通大学医学院附属仁济医院上海市肿瘤研究所(下称:上海市肿瘤研究所)与荷兰癌症研究所合作研究创新制定了肝癌治疗精准策略。

科学家们利用肝癌细胞的自身特点,如相关基因突变,先将肝癌细胞诱导进入细胞衰老状态,再特异清除肝癌细胞,这样的治疗模式对人体正常生长细胞并无影响。这种组合拳式或分步式(“One-twopunch”)治疗,可避免患者接受化疗,因严重毒副作用而受苦的现状。

上海市肿瘤研究所研究员覃文新告诉记者,肝癌精准治疗策略有望为包括肝癌在内的肿瘤精准治疗提供新思路。3日,Nature《自然》在线发表了这项合作研究成果。

中国是肝癌“重灾区”,在全球每年新增肝癌病例中,中国新增与死亡病例占比不小。据介绍,肝癌是一种多基因参与、多因素介导、病理机制复杂的恶性肿瘤。当下,对于早期肝癌,手术切除和肝移植仍是最为有效的治疗手段。但由于肝癌早期诊治困难,病情进展快、预后较差,大部分患者在确诊时已失去了手术机会。据覃文新介绍,针对细胞增殖特点研发的抗肿瘤化疗药物,“杀敌一千,自损八百”,在杀死癌细胞的同时也杀死人体内增殖更新的正常细胞,毒副作用严重,仅能非常有限地延长肿瘤患者的生存期。

随着基因组测序技术的高速发展和广泛应用,人们对肝癌基因组特性有了较为深入的了解,研究表明,肝癌的主要突变类型并不能直接作为有效的药物靶点。因此,作为中晚期肝癌患者标准疗法的非特异性的多靶点药物,临床疗效十分有限。

在中国与荷兰科学家创新制定的肝癌精准策略中,第一招是“虚招”,医生们可以利用肿瘤细胞存在的特异突变,将其诱导到某种特定状态,如细胞衰老状态,使肿瘤细胞露出“破绽”。接下来组合拳的第二招为“实招”,医生们可精准地将衰老的肿瘤细胞清除掉。
