儿童恶性肿瘤的质子治疗研究进展

儿童恶性肿瘤是全球儿童的主要死因。放疗是儿童恶性肿瘤的重要治疗手段,但引起的急慢性不良反应往往影响患儿生存期和生存质量。质子治疗作为一种前沿放疗技术,能保证精确的靶区剂量,同时降低邻近组织和器官受量。已有较多的研究显示恶性肿瘤患儿对质子线的耐受较好,质子治疗能保证较好的肿瘤控制效果,同时在生存质量、智商保护、降低第二肿瘤风险等方面可能优于以X线为代表的传统放疗技术。本文旨在综述质子放疗技术应用于儿童恶性肿瘤临床治疗研究进展。

Research advances in proton therapy for pediatric cancer

Pediatric cancer is one of the leading causes of death in children around the world.Although radiotherapy is an important means of treatment for pediatric cancer,it causes acute or chronic adverse events that may affect patients' survival time and quality of life.As a novel and advanced radiation technique,proton therapy allows for precise dose delivery in target volume,significantly reducing the irradiation to surrounding tissues and organs.Studies have shown that proton therapy is well tolerated in the treatment of pediatric cancer,and it achieves good tumor control;proton therapy is superior to traditional radiotherapy in improving quality of life,protecting intelligence,and reducing the risk of secondary cancer.This article reviews the research advances in the application of proton therapy in the treatment of pediatric cancer.
