Data concerning megavoltage equipment and use of megavoltage external beams in cancer management during 1987 in Denmark, Finland, Iceland, Norway, and Sweden were collected from all 37 centres serving a population of 23 million in these countries. Population per Linear Accelerator Equivalent (LAE) unit ranged from 0.30 million/LAE unit (Denmark) to 0.19 million/LAE unit (Sweden). The number of field treatments were 227,548 (Denmark), 259,917 (Finland), 10,426 (Iceland), 147,960 (Norway) and 490,126 (Sweden). The number of field treatments per million population per year ranged from 35,229 (Norway) to 58,438 (Sweden). The number of field treatments per LAE unit/year ranged from 13,192 (Denmark) to 9,546 (Norway). The fraction of cancer patients receiving megavoltage radiotherapy in 1987 out of all newly diagnosed cancer patients during 1987 was 24% in Denmark, 37% in Iceland, 25% in Norway, and 34% in Finland and Sweden. We conclude that Denmark and Norway probably did not provide adequate levels of radiotherapy for their cancer patients during 1987.
收集了丹麦、芬兰、冰岛、挪威和瑞典1987年期间有关兆伏级设备以及在癌症治疗中使用兆伏级外照射束的数据，这些数据来自为这些国家2300万人口服务的所有37个中心。每线性加速器等效（LAE）单位的人口数从0.30百万/LAE单位（丹麦）到0.19百万/LAE单位（瑞典）不等。野照射治疗次数分别为227,548次（丹麦）、259,917次（芬兰）、10,426次（冰岛）、147,960次（挪威）和490,126次（瑞典）。每年每百万人口的野照射治疗次数从35,229次（挪威）到58,438次（瑞典）不等。每年每个LAE单位的野照射治疗次数从13,192次（丹麦）到9,546次（挪威）不等。1987年接受兆伏级放射治疗的癌症患者在1987年所有新诊断癌症患者中所占的比例，在丹麦为24%，在冰岛为37%，在挪威为25%，在芬兰和瑞典为34%。我们得出结论，在1987年期间，丹麦和挪威可能没有为其癌症患者提供足够的放射治疗水平。
