This survey is performed to learn about the structure of radiotherapy in México.
Radiation oncology practice is increasing because of the higher incidence of cancer. There is no published data about radiotherapy in México.
A questionnaire was sent to the 83 registered centers in the database of the Mexican regulatory agency. One out of the 32 states has no radiotherapy. 27 centers from 14 states provided their answers.
829 patients are treated annually with any radiotherapy modality in each center. Two centers have one cobalt machine, 7 have a cobalt and a linac and 10 have more than one linac. Five centers use 2D planning systems, 22 use 3D; 9, conventional simulators; 22, CT based simulation, and 1 center has no simulation. Most of the centers verify beams with films, electronic portal image devices and cone beam CTs are also used. Intensity modulated and image guided radiotherapy are performed in 5 states. Breast, prostate, cervix, lung, rectum and head and neck cancer are the six most common locations. There are 45 public and 38 private centers, 2 dedicated to children. Two gamma knife units, 5 Novalis systems, 1 tomotherapy and 2 cyberknife machines are working. All centers have at least one radiation oncologist, one physicist and one radiotherapist.
Definitive conclusions cannot be drawn from this limited feedback due to a low participation of centers. This survey about radiotherapy in Mexico shows the heterogeneity of equipment as well as medical and technical staff in the whole country.
开展本次调查以了解墨西哥放射治疗的结构。
由于癌症发病率上升,放射肿瘤学实践正在增加。墨西哥尚无关于放射治疗的已发表数据。
向墨西哥监管机构数据库中的83个注册中心发送了一份调查问卷。32个州中有1个州没有放射治疗。来自14个州的27个中心提供了答复。
每个中心每年用任何放射治疗方式治疗829名患者。2个中心有1台钴机,7个中心有1台钴机和1台直线加速器,10个中心有不止1台直线加速器。5个中心使用二维计划系统,22个使用三维系统;9个使用传统模拟机,22个使用基于CT的模拟,1个中心没有模拟设备。大多数中心用胶片验证射束,也使用电子射野影像装置和锥形束CT。5个州开展调强放疗和影像引导放疗。乳腺癌、前列腺癌、宫颈癌、肺癌、直肠癌以及头颈癌是六个最常见的部位。有45个公立中心和38个私立中心,2个专门治疗儿童。有2台伽马刀装置、5套诺力刀系统、1台断层放射治疗机和2台射波刀在运行。所有中心至少有一名放射肿瘤学家、一名物理学家和一名放射治疗师。
由于中心参与度低,无法从这一有限反馈中得出明确结论。这项关于墨西哥放射治疗的调查显示了全国设备以及医护和技术人员的异质性。
