To examine the availability of radiotherapy in small countries.
A small country was defined as a country with a population less than one million persons. The economic status of each country was defined using the World Bank Classification. The number of cancers in each country was obtained from GLOBOCAN 2012. The number of cancer cases with an indication or radiotherapy was calculated using the CCORE model.
There were 41 countries with a population of under 1 million; 15 were classified as High Income, 15 Upper Middle Income, 10 Lower Middle Income and one Low Income. 28 countries were islands. Populations ranged from 799 (Holy See) to 886450 (Fiji) and the total number of cancer cases occurring in small countries was 21,043 (range by country from 4 to 2476). Overall the total number of radiotherapy cases in small countries was 10982 (range by country from 2 to 1239). Radiotherapy was available in all HIC islands with 80 or more new cases of cancer in 2012 but was not available in any LMIC island. Fiji was the only LMIC island with a large radiotherapy caseload. Similar caseloads in non-island LMIC all had radiotherapy services. Most non-island HIC did not have radiotherapy services presumably because of the easy access to radiotherapy in neighbouring countries.
There are no radiotherapy services in any LMIC islands.
研究小国放疗服务的可及性。
小国定义为人口少于100万的国家。各国经济状况依据世界银行分类确定。各国癌症病例数取自2012年全球癌症负担数据（GLOBOCAN 2012）。使用CCORE模型计算有放疗指征的癌症病例数。
有41个人口不足100万的国家；其中15个为高收入国家，15个为中高收入国家，10个为中低收入国家，1个为低收入国家。28个国家为岛国。人口数从799人（梵蒂冈城国）到886450人（斐济）不等，小国发生的癌症病例总数为21,043例（各国范围从4例到2476例）。总体而言，小国放疗病例总数为10982例（各国范围从2例到1239例）。2012年所有高收入国家的岛国只要有80例或更多新发癌症病例就有放疗服务，但中低收入国家的岛国均无放疗服务。斐济是唯一放疗病例数较多的中低收入国家的岛国。非岛国的中低收入国家类似病例数的地区均有放疗服务。多数非岛国的高收入国家没有放疗服务，大概是因为邻国放疗服务可及性高。
所有中低收入国家的岛国均无放疗服务。
