我国首台完全自主知识产权重离子治癌系统进入临床试验

2018-05-26 19:01:06   新华网

新华社兰州5月26日电(记者梁军)记者26日从甘肃省武威重离子治疗中心获悉,我国首台拥有自主知识产权的重离子治癌系统正式进入临床试验阶段,这标志着我国重离子治疗系统在注册上市和产业化发展道路上迈出关键一步。

据介绍,北京市医疗器械检验所承担、甘肃省医疗器械检验所配合历时两年,对武威重离子治疗系统进行注册检验,完成了电磁兼容、安规、电器安全等1300个组件检验。今年4月注册检验全部完成,武威重离子治癌系统达到技术标准规定,可以进入临床试验。

记者了解到,甘肃省肿瘤医院、武威肿瘤医院已遴选了病例,将牵头开展头颈、胸、腹、盆腔、四肢肿瘤的临床验证治疗。为确保临床试验的科学性和安全性,甘肃省成立了由36名国内知名专家组成的武威重离子治癌系统临床试验专家委员会,加强临床试验专家指导。

中国科学院近代物理研究所所长肖国青说,该所从1993年开始重离子治癌技术基础研究,历经20多年的技术积累和科研攻关,掌握了回旋注入器、同步环加速器、治疗床等相关硬件技术,自主研发了治疗计划、治疗控制等软件,在甘肃省武威市和兰州市建造了两台具有完全自主知识产权的重离子治疗系统,使我国成为全世界组织生产重离子治癌系统的两个国家之一。

肖国青说,重离子治疗肿瘤是目前各国研究的高精尖技术热点,也是公认先进有效的治疗肿瘤方法。对于患者来说,与传统放射治疗肿瘤的电子、X等常规射线相比,重离子束具有对健康组织辐射损伤轻、疗程短、控制率高等特点。

同时,重离子治癌系统的注册上市和产业化,将催生出批量的加速器、核探测设备的加工制造市场需求,拉动相关装备制造业的技术进步和产业繁荣,形成数千亿元的重离子治疗产业集群。

我国是世界上第四个开展重离子肿瘤治疗临床试验研究的国家。从上世纪70年代以来,先后有美国、德国、日本和中国开始利用重离子束治疗肿瘤的试验研究。
