解决全球儿童癌症的负担:找到希望之光

每年,全世界约有40万名儿童患有癌症,但其中只有一半患儿能被诊断出来。

国际原子能机构的“希望之光”倡议旨在通过改善放射治疗、医学成像和核医学的可获得性来促进全民癌症护理,这些服务在癌症的检测和治疗过程中扮演着至关重要的角色。该倡议得到了多个机构的支持,其中包括中国国家原子能机构(CAEA)。(图片来源:S. Vichare/国际原子能机构) 

每年,全世界约有40万名儿童患有癌症,但其中只有一半患儿能被诊断出来。他们中大多数人生活在中低等收入国家,最多也只有30%可以被治愈。营养不良、误诊、无法获得治疗以及缺乏专业卫生人员等因素加剧了儿童需要遭受这种不必要的痛苦。

国际原子能机构副总干事兼核科学和应用部部长纳贾特·穆赫塔尔在国际原子能机构第六十七届大会期间一场关于“抗击儿童癌症:找到希望之光”的边会上开幕致辞:“原子能机构正在努力纠正这一现实,为这些儿童提供应有的照顾。”她表示:“原子能机构在整个护理过程中利用科学专门知识、带着善意、提供相应机会加强其成员国的能力,为成员国及成员国的儿童提供对抗癌症的机会。”

Sidney Chahonyo的故事生动地展现了原子能机构所作出的努力对于全球像他一样的患者到底意味着什么。Chahonyo十九岁时,正当他即将进入大学,便开始出现头痛和流鼻血的症状。随其症状的频率和强度不断增加,再加上开始出现听力损失,迫使他寻求医疗护理。然而,令人沮丧是,经过六个月走访并问诊于多家医院诊所,他却屡遭误诊,最终才被确诊为患有鼻咽癌。这是一种影响连接鼻子后部和口腔后部组织的癌症。确诊后,他随即接受了治疗。如今,作为三十七岁的癌症幸存者,他担任“癌症儿童的希望”组织的执行董事,该组织是一个非营利组织,致力于为肯尼亚受儿童癌症影响的家庭提供支持、资源和希望。Chahonyo表示:“我希望世界各地的每个孩子都能有机会和我一样战胜癌症。”

在高收入国家,几乎所有患者都能接受放射治疗。在中等收入国家,不到60%的患者能够获得治疗。而在低收入国家,只有十分之一的人能够有机会获得这种可以挽救生命的治疗。原子能机构“希望之光:全民癌症护理”的倡议旨在通过相应支持帮助世界各地建立和扩大放射治疗服务来改善这一现况。

此次边会活动重点介绍了放射医学技术和营养在治疗儿童癌症方面的作用。原子能机构专家以髓母细胞瘤(儿童最常见的恶性脑肿瘤)为案例研究,详细描述了患者接受的护理情况。专家强调称,影像学、治疗、质量保证和营养支持方面的最新进展不仅可以提高生存率,还可以减少儿童经历的副作用。

原子能机构及其合作伙伴一直在努力为所有儿童提供公平的癌症护理机会。其中三个合作伙伴 — 世界卫生组织儿童癌症全球倡议、儿科放射肿瘤学会和欧洲安全儿科影像工作组 — 的代表们强调了确保可持续且高质量护理的重要性。

尽管全球在改善儿童癌症护理方面取得了进展,但仍需解决诸多挑战,包括缩小各国在资金、设备、基础设施、教育、培训和人力资源等方面的差距。

尽管这些挑战看起来十分艰巨,但我们有明确的前进方向和具体的步骤措施。

原子能机构人体健康司司长May Abdel Wahab在闭幕词中强调:“通过持续合作、科学专门知识、全球意愿和承诺,我们能够应对这些挑战并满足世界各地癌症儿童的需求。” 她表示:“我们一定要兑现承诺,并且我们永远不能忘记获得护理是一项道德要求和人类权利。”

In high-income countries nearly all patients have access to radiotherapy. In middle-income countries fewer than 60 percent do. In low-income countries, only one in ten people has access to this life-saving treatment. The IAEA’s flagship cancer initiative Rays of Hope: Cancer Care for All sets out to improve that by supporting the establishment and expansion of radiotherapy services around the world.

The side event spotlighted the role of radiation medicine techniques and nutrition in managing childhood cancers. Focusing on medulloblastoma – the most common malignant brain tumour in children – as a case study, IAEA experts described the care that patients receive. They underscored that recent advances in imaging, treatment, quality assurance and nutritional support have not only improved survival but also reduced the side effects that children experience. 

Child by child, the IAEA and its collaborators have been making strides toward equitable cancer care for all. Representatives of three of those collaborators – the WHO Global Initiative for Childhood Cancer, the Paediatric Radiation Oncology Society and the EuroSafe Imaging Working Group on paediatric imaging – underlined the importance of ensuring that care is both continuous and of a high quality.  

Yet, despite global progress, there are a number of challenges that still need to be addressed to close the gap between countries in terms of funding, equipment, infrastructure, education, training and human resources, to name but a few. 

As immense and as daunting as these challenges may seem, there is a clear way forward and concrete steps that can be taken. 

“With continued collaboration, scientific expertise, global will and commitment, we can tackle these challenges and meet the needs of children with cancer around the world," May Abdel-Wahab, Director of the IAEA’s Division of Human Health, underscored in her closing remarks. “We cannot fail to deliver," she said, “and we must never forget that access to care is a moral imperative and human right.”
