癌症不仅是人们的一个主要健康问题,而且也是一个对国家福祉和政府卫生预算造成严重后果的日益严峻的发展挑战。据世界卫生组织国际癌症研究机构估计,2010年癌症的年度经济费用总额估计为1.16万亿美元。随着每年有更多的人患癌症,这一数字预计将继续增加:2018年,全球癌症病例数量超过1800万,死亡数量为960万。到2030年,这些年度数字预计将上升到2400万例,死亡数量达到1300万。

许多低收入和中等收入国家无法提供足够的癌症诊断和治疗服务,必须将患者送往国外接受护理,因而费用高昂,可能给患者及其家庭带来负担。建立包括放射治疗设施和核医学部门在内的国家癌症护理服务是一项复杂的任务,需要仔细规划,以建立高度专业化的基础设施、设备和培训,并调动资金。

原子能机构长期以来一直在支持各国利用核技术促进健康。在癌症领域,它一直在转让技术,并建设人员和机构利用辐射技术进行癌症诊断和治疗的能力。原子能机构通过其技术合作计划,自2011年以来对2000多名医疗卫生专业人员进行了培训,并提供了超过1.72亿欧元,以协助各国发展国家癌症护理服务。仅在2019年,它就为全球超过125个癌症相关项目提供了支持。

原子能机构副总干事兼技术合作司司长杨大助说:“我们的目标是与我们的成员国,特别是低收入和中等收入国家的成员国合作,建设和加强它们在癌症防治方面的能力,以便更多的患者能够安全有效地得到治疗。”

原子能机构在这一领域的支持包括在这一进程的所有阶段建设人力资源的专门培训和专家建议,以及建立业务设施并能够提供服务所需的工具、材料和设备。

这种支持的影响可以在斯里兰卡等国家看到。斯里兰卡40多年来一直与原子能机构合作发展该国的癌症护理服务。例如,在过去八年中,这种合作促进了核医学成像能力的提高,使训练有素的专家能够在斯里兰卡提供诊断服务。

在斯里兰卡中部,已在康提市建立了一个设备齐全的核医学部门,以补充该国南部城市加勒的一个类似设施。在北部贾夫纳附近也正在建立一个新的设施。2019年10月,斯里兰卡预计将接待一次原子能机构“治疗癌症行动计划”综合评定工作组评审访问,专家将在此访问中评定该国的进

展并协助制定其未来癌症防治发展计划。

规划、供资、协作

许多国家与原子能机构合作,以便在癌症防治优先事项的规划、资金筹集和开展合作方面获得帮助。原子能机构协助组织和促进与捐助者、开发银行和金融机构的讨论。

例如,在尼加拉瓜,与卫生部密切合作,并在日本双边资助的支持下,该国的第一台直线加速器(一种先进放射治疗机器)于2019年5月在国家放射治疗中心落成。原子能机构支持对新系统的工作人员进行专家培训,以确保从现有临床实践有效过渡到最新的3D放射治疗,从而实现更安

全、更优质的治疗。这是该国癌症治疗服务的一个重要里程碑,将允许执行高度专业化的放射治疗技术。

同样,蒙古的放射治疗服务也得到了改善,两台直线加速器于2019年6月投入使用。用于确保患者接受正确放射剂量的质量保证系统得到了升级,还引入了用于放射治疗服务的新技术和放射安全系统。此外,捐助者在2016年为一个最先进的癌症诊断和治疗系统提供了支助,通过原子能机构援助进行的培训帮助向该国引入了高精度3D放射疗法和其他现代技术。

随着各国为新设施的开放做准备,原子能机构与领先的国际医疗机构合作,提供专家培训和进修,以帮助确保癌症护理服务具有足够数量的训练有素的工作人员,例如肿瘤学家、放射学家和医学物理师。

培训专业人员

乍得首都恩贾梅纳利摩日大学医院母婴医院的肿瘤学家Fatima Haggar说,建立一支训练有素、随时可以操作新设施的国家熟练医疗专业人员队伍,需要在时间上精心安排,往往提前数年启动。“我们的新中心将在大约三年后开业,我们需要一段时间才能使所有工作人员都具备资格。”

乍得最近制定了一份规划和资助文件,以建立其第一个放射治疗设施,作为其2017-2021年国家癌症防治计划的一部分。原子能机构正在通过与政府分担长期和短期进修费用并提供咨询意见和专家评定,协助该国对工作人员进行必要的培训。

鉴于癌症治疗设施的规模和复杂性,只有在各国政府的密切参与和广泛利益攸关方的合作下,才能取得进展。各国政府需要将癌症确定为国家卫生优先事项,以确保在国家卫生计划、卫生预算、基础设施发展、筹资和能力建设等各个层面采取行动,解决国家癌症负担。

例如,对塞拉利昂这样的国家来说,政府最高层对癌症挑战的认识意味着,该国完全有能力在国家防治癌症方面取得进展。

“我们的总统认识到癌症正在给国家造成巨大的负担,”塞拉利昂健康和卫生部的放射学家和联络人Frank Kosia说。“他的旗舰项目希望到2023年能够公开获得放射治疗。”原子能机构正在与塞拉利昂政府合作实现这一目标,为在拉卡医院建立放射治疗和核医学设施提供支持,该医院将扩大以满足这些服务。

Planning, funding, collaboration

Many countries work with the IAEA to get help in planning, raising funds and developing collaborations for cancer control priorities. The IAEA assists in organizing and facilitating discussions with donors, development banks and financial institutions.

In Nicaragua, for example, in close collaboration with the Ministry of Health and with the support of bilateral funding from Japan, the country’s first linear accelerator, or linac, an advanced radiotherapy machine, was inaugurated in May 2019 at the National Radiotherapy Centre. The IAEA supported specialist training of staff for the new system to ensure an effective transition from the existing clinical practice to the latest 3D radiotherapy, allowing for safer and better-quality treatment. This is an important milestone for the country’s cancer treatment services and will allow highly specialized radiotherapy techniques to be performed.

Similarly, radiotherapy services in Mongolia have been improved, and two linacs became operational in June 2019. Quality assurance systems for ensuring that patients receive the correct radiation doses were upgraded, and new technologies and a radiation safety system for radiotherapy services were also introduced. In addition, donors provided support in 2016 for a state-of-the-art cancer diagnosis and treatment system, and training through IAEA assistance helped to introduce highly accurate 3D radiation therapy and other modern technologies to the country.

As countries prepare for their new facilities to open, the IAEA, in partnership with leading international medical institutions, provides specialist training and fellowships that help ensure cancer care services have a sufficient number of well-trained staff, such as oncologists, radiologists and medical physicists.

Training professionals

Building a national cohort of skilled medical professionals, trained and ready to operate new facilities, requires carefully timed support, often initiated years in advance, said Fatima Haggar, Medical Oncologist at the Mother and Child Hospital (Hôpital de la mère et de l’enfant) in N’Djamena. “Our new centre will open in around three years, and it will take time for all the staff we need to become qualified.”

Chad has recently developed a planning and funding document to establish its first radiotherapy facility as part of its National Cancer Control Plan 2017–2021. The IAEA is assisting the country with the required training of staff by sharing the cost of long- and short-term fellowships with the Government and providing advice and expert assessments.

Given the scale and complexity of cancer treatment facilities, progress can only be made with the close involvement of national governments and the cooperation of a broad range of stakeholders. Governments need to identify cancer as a national health priority to ensure that actions to address the national cancer burden are taken at every level — in national health plans, health budgeting, infrastructure development, fundraising and capacity building.

For a country like Sierra Leone, for example, recognition of the challenge of cancer at the very highest level of government means that the country is well positioned to make progress in the national fight against cancer.

“Our President recognizes that cancer is creating a huge burden for the country,” said Frank Kosia, radiologist and focal point for the Ministry of Health and Sanitation in Sierra Leone. “His flagship project looks to make radiotherapy publicly available by 2023.” The IAEA is working with the Government of Sierra Leone to make this goal a reality, providing support for the establishment of radiotherapy and nuclear medicine facilities at Lakka Hospital, which will be expanded to accommodate these services.
