Three-dimensional printing in radiation oncology: A systematic review of the literature.

ABSTRACT: PURPOSE/OBJECTIVES:Three-dimensional (3D) printing is recognized as an effective clinical and educational tool in procedurally intensive specialties. However, it has a nascent role in radiation oncology. The goal of this investigation is to clarify the extent to which 3D printing applications are currently being used in radiation oncology through a systematic review of the literature. MATERIALS/METHODS:A search protocol was defined according to preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Included articles were evaluated using parameters of interest including: year and country of publication, experimental design, sample size for clinical studies, radiation oncology topic, reported outcomes, and implementation barriers or safety concerns. RESULTS:One hundred and three publications from 2012 to 2019 met inclusion criteria. The most commonly described 3D printing applications included quality assurance phantoms (26%), brachytherapy applicators (20%), bolus (17%), preclinical animal irradiation (10%), compensators (7%), and immobilization devices (5%). Most studies were preclinical feasibility studies (63%), with few clinical investigations such as case reports or series (13%) or cohort studies (11%). The most common applications evaluated within clinical settings included brachytherapy applicators (44%) and bolus (28%). Sample sizes for clinical investigations were small (median 10, range 1-42). A minority of articles described basic or translational research (11%) and workflow or cost evaluation studies (3%). The number of articles increased over time (P < 0.0001). While outcomes were heterogeneous, most studies reported successful implementation of accurate and cost-effective 3D printing methods. CONCLUSIONS:Three-dimensional printing is rapidly growing in radiation oncology and has been implemented effectively in a diverse array of applications. Although the number of 3D printing publications has steadily risen, the majority of current reports are preclinical in nature and the few clinical studies that do exist report on small sample sizes. Further dissemination of ongoing investigations describing the clinical application of developed 3D printing technologies in larger cohorts is warranted.

Project description:PurposeAlthough mentorship is described extensively in academic medical literature, there are few descriptions of mentorship specific to radiation oncology. The goal of the current study was to investigate the state of mentorship in radiation oncology through a scoping review of the literature.Methods and materialsA search protocol was defined according to Preferred Reporting Items for Systematic Reviews and Meta Analyses extension for scoping reviews (PRISMA-ScR) guidelines. Predefined search terms and medical subject headings were used to search PubMed for English language articles published after January 1, 1990, on mentorship in radiation oncology. Additionally, in-press articles from major radiation oncology and medical education journals were searched. Three reviewers determined article eligibility. Included articles were classified based on predefined evaluation criteria.ResultsFourteen publications from 2008 to 2019 met inclusion criteria. The most commonly described form of mentorship was the dyad (64.3%), followed by team (14.3%) and peer (7.1%); 2 articles did not specify mentorship type (14.3%). The most commonly mentored participants were residents (35.7%), followed by medical students (35.7%) and attendings (21.4%); 1 study included participants of all levels (7.1%). Thirteen studies (92.9%) identified an experimental study design, most of which were cross-sectional (42.9%), followed by cohort studies (28.6%) and before/after (21.4%). Median sample size, reported in 12 of 13 experimental studies, was 132 (coefficient of variation, 1.06). Although outcomes varied widely, the majority described successful implementation of mentorship initiatives with high levels of participant satisfaction.ConclusionsAlthough few initiatives are currently reported, the present study suggests that these initiatives are successful in promoting career development and increasing professional satisfaction. The interventions overwhelmingly described mentorship dyads; other forms of mentorship are either less common or understudied. Limitations included interventions not being evaluated in a controlled setting, and many were assessed using surveys with low response rates. This review highlights rich opportunities for future scholarship to develop, evaluate, and disseminate radiation oncology mentorship initiatives.
