Perceptions of Canadian Radiation Oncologists, Medical Physicists, and Radiation Trainees about the Feasibility and Need of Boron Neutron Capture Therapy (BNCT) in Canada: A National Survey
CANCERS(2023)
摘要
Simple Summary Technological advancements in accelerator-based neutron sources have allowed for a more accessible and feasible study of Boron Neutron Capture Therapy (BNCT). Accelerator-based BNCT centers are being developed world-wide, and recent research is showing the potential in treating cancers. There are ongoing efforts to initiate Canadian contributions to BNCT research and the development of a Canadian center. We surveyed radiation oncologists and medical physicists in Canada to study their perception, understanding, and support for BNCT. The results of this survey guide Canadian contributions by identifying knowledge gaps and collaborative opportunities that support the success of this innovative cancer treatment in Canada. Background: Boron Neutron Capture Therapy (BNCT) is an emerging radiotherapy. There are ongoing efforts to develop a Canadian accelerator-based BNCT center. However, it remains unclear how Canadian radiation oncologists (RO), medical physicists (MP), and their trainees perceive BNCT and its impact on radiation oncology as a discipline. Methods: A survey was created to explore the knowledge of BNCT, its clinical role, and the support for Canadian research. It was distributed through the Canadian Association of Radiation Oncology (CARO) and the Canadian Organization of Medical Physicists (COMP). Results: We received 118 valid responses from all 10 provinces, from 70 RO (59.3%) and 48 MP (40.7%), including 9 residents. Most knew of BNCT and its indications (60.2%). Although many were unaware of the reasons behind early failures (44.1%), common reasons were a lack of clinical trials and an inaccessibility of neutron sources (42.4%) as well as reactor unsuitability (34.7%). Additionally, 90.6% showed definite (66.9%) or possible (23.7%) support for Canadian BNCT research, while 89% indicated a definite (56.8%) or possible (32.2%) willingness for BNCT referrals. Conclusions: Most ROs and MPs supported Canadian BNCT research and would refer patients. However, limited awareness and a lack of experiences remain a challenge. Educational sessions are needed to realize this innovative cancer treatment in Canada.
