11039 Background: Gynecologic cancers are one of the leading causes of death globally with a disproportionate burden of disease found in low to middle income countries (LMIC). Brachytherapy is often a necessary component in treatment management as it can deliver a high dose of radiation to the tumor while employing a steep dose fall off that spares the adjacent organs at risk. With 3D image guided brachytherapy (3D-IGBT), treatment planning utilizes volumetric images with the target volume and organs at risk contoured, reducing toxicity and improving outcomes when compared to 2D planar imaging. Despite this advantage, only a limited number of LMIC centers perform 3D-IGBT. Transitioning to 3D-IGBT requires considerable planning, resources, and training. The development of a multidisciplinary, computer-based training program to facilitate the transition to 3D-IGBT was identified as a priority of multiple Radiation Oncology departments in Nigeria. The aim of this preliminary needs assessment was to identify the necessary resources and anticipated barriers to development of a pilot training curriculum for the transition to 3D-IGBT. Methods: An anonymous, 16-question online survey was distributed to clinicians, physicists, radiation therapists, and staff within a Radiation Oncology department of a teaching hospital in Lagos, Nigeria. Results: In January 2023, 53 respondents completed the survey. Of the respondents, 36.5% were female and 63.5% were male. The average age was 37.5 (SD = 7.8). Clinical experience ranged from < 5 years (52.6%), 6-10 years (9.4%), to > 10 years (30.2%). Respondents included radiation therapists (28.8%), clinicians (27%), nurses (23.1%), and physicists (15.4%). Multiple barriers to implementation of 3D-IGBT were identified including lack of training (79.2%) or experience (58.5%), lack of financial investment (50.9%), and anticipated repair/replacement of equipment (41.5%). A majority of respondents identified staff training/education (66%) as critical to delivering 3D-IGBT. When asked about the curriculum components needed, most respondents believed that it should include plan review (96.2%), contour review (94.3%), and peer review of clinical cases (92.5%). Conclusions: Various areas of potential need were identified through this preliminary needs assessment, most notably, staff training. These findings suggest that there is an unmet need to further develop and implement a structured didactic and skills-based curriculum to transition from 2D to 3D-IGBT at these institutions. Identified focus areas including contour, peer, and plan review will help guide the refinement of this curriculum. These findings are an important first step in delivery of safe and efficacious 3D-IGBT in an LMIC.
