To determine the current use of brachytherapy, characteristics of the brachytherapy workforce, and barriers to development and maintenance of brachytherapy programs across Canada.
A survey was designed to inquire about the use of brachytherapy and was sent to all Canadian radiation oncologists.
Of the 116 respondents, we identified 80 radiation oncologists from 33 of 41 responding centers who currently or in the past have practiced brachytherapy. Responses were received from 30% overall and 80% of provinces. Approximately 58% of the respondents treat in one site with brachytherapy, whereas 12% treat in three or more sites. Gynecologic (GYN) and genitourinary are the most commonly treated sites (49% of respondents). For all sites, there was a large range in the number of patients treated with brachytherapy by each radiation oncologist per year (i.e., cervix: 1-50). Approximately 49% of the respondents have discontinued practicing brachytherapy for a certain site, most commonly head and neck (28%), GYN (25%), and bronchus (24%). The most common reasons include reassignment or lack of a local program. The most common reasons why brachytherapy is not used for sites other than GYN and prostate include lack of infrastructure and insufficient training of radiation oncologists rather than insufficient patient numbers or lack of evidence for a benefit of brachytherapy.
Within its limitations, our study suggests a mismatch between demand and availability of brachytherapy programs across Canada. In light of finite resources, a rational approach to investment in brachytherapy is needed and this must be based on a formal audit of brachytherapy demand and use.
确定加拿大近距离放射治疗的当前使用情况、近距离放射治疗从业人员的特点以及全国范围内近距离放射治疗项目发展和维持的障碍。
设计了一项关于近距离放射治疗使用情况的调查,并发送给了所有加拿大放射肿瘤学家。
在116名受访者中,我们从41个回复中心中的33个中心识别出80名目前或过去从事过近距离放射治疗的放射肿瘤学家。总体回复率为30%,各省的回复率为80%。约58%的受访者在一个地点进行近距离放射治疗,而12%的受访者在三个或更多地点进行治疗。妇科(GYN)和泌尿生殖系统是最常治疗的部位(49%的受访者)。对于所有部位,每位放射肿瘤学家每年进行近距离放射治疗的患者数量差异很大(例如,子宫颈:1 - 50例)。约49%的受访者已停止在某个部位进行近距离放射治疗,最常见的是头颈部(28%)、妇科(25%)和支气管(24%)。最常见的原因包括工作调动或当地项目缺失。除妇科和前列腺外,近距离放射治疗未用于其他部位的最常见原因包括基础设施不足和放射肿瘤学家培训不足,而非患者数量不足或缺乏近距离放射治疗有益的证据。
在其局限性范围内,我们的研究表明加拿大各地近距离放射治疗项目的需求与可及性之间存在不匹配。鉴于资源有限,需要一种合理的近距离放射治疗投资方法,这必须基于对近距离放射治疗需求和使用情况的正式审核。
