[PMID: 36933402 PMCID: PMC10245278 DOI: 10.1016/j.ygyno.2023.03.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Revised: 02/26/2023] [Accepted: 03/01/2023] [Indexed: 03/18/2023]
Abstract
STUDY OBJECTIVE There is scant research identifying thematic trends within medical research. This work may provide insight into how a given field values certain topics. We assessed the feasibility of using a machine learning approach to determine the most common research themes published in Gynecologic Oncology over a thirty-year period and to subsequently evaluate how interest in these topics changed over time. METHODS We retrieved the abstracts of all original research published in Gynecologic Oncology from 1990 to 2020 using PubMed. Abstract text was processed through a natural language processing algorithm and clustered into topical themes using latent Dirichlet allocation (LDA) prior to manual labeling. Topics were investigated for temporal trends. RESULTS We retrieved 12,586 original research articles, of which 11,217 were evaluable for subsequent analysis. Twenty-three research topics were selected at the completion of topic modeling. The topics of basic science genetics, epidemiologic methods, and chemotherapy experienced the greatest increase over the time period, while postoperative outcomes, reproductive age cancer management, and cervical dysplasia experienced the greatest decline. Interest in basic science research remained relatively constant. Topics were additionally reviewed for words indicative of either surgical or medical therapy. Both surgical and medical topics saw increasing interest, with surgical topics experiencing a greater increase and representing a higher proportion of published topics. CONCLUSIONS Topic modeling, a type of unsupervised machine learning, was successfully used to identify trends in research themes. The application of this technique provided insight into how the field of gynecologic oncology values the components of its scope of practice and therefore how it may choose to allocate grant funding, disseminate research, and participate in the public discourse.

Abstract
PURPOSE The aim of this study is to identify the leaders in research on prostate brachytherapy through a bibliometric analysis of the top 100 most cited publications in the field. METHODS AND MATERIALS A broad search was performed with the term "prostate brachytherapy" using the Web of Science database to generate wide-ranging results that were reviewed by reading the abstracts and, if necessary, the articles to select the top 100 most cited publications. RESULTS The median of the total citation count was 187 (range 132-1464). The median citation per year index (citations/year since publication) was 13.5 (range 6.3-379.0). In all publications, the first author was also the corresponding author. The top publishing countries of the first author included the United States (n = 78), Canada (n = 6), the UK (n = 5), and Germany (n = 4). The journal with the most publications was the International Journal of Radiation Oncology Biology Physics (n = 38). There were 27 more publications on low-dose-rate (LDR) than on high-dose-rate (HDR) (43 vs 16) among the top 100. HDR publications had only one first author that had three articles in comparison to LDR publications, which had four first authors, each with three articles on LDR. The United States was the leading country in 43.8% of HDR publications (n = 7) and 88.4% of LDR publications (n = 38). CONCLUSIONS Our bibliometric analysis of the top 100 most cited publications clearly demonstrates the North American dominance in the publications of prostate brachytherapy, especially in LDR. However, European first authors were more frequent in HDR publications.

Abstract
PURPOSE This study aimed to integrate and update the dose-effect relationship between volumetric dose and local control for cervical cancer brachytherapy. METHODS AND MATERIALS We identified studies that reported high-risk clinical target volume (HR-CTV) D90 and local control probability by searching PubMed, Web of Science, and the Cochrane Library databases through Oct 27, 2019. The regression analyses were performed using a probit model between HR-CTV D90, D100, intermediate-risk clinical target volume (IR-CTV) D90, and dose to Point A vs. local control probability. Subgroup analyses were performed according to stratification: time of local control, income level of the country or region, stage of cancer, pathology, mean volume of HR-CTV, dose rate, image modality, concurrent chemoradiotherapy proportion, interstitial proportion, and mean overall treatment time. RESULTS Thirty-three studies encompassing 2893 patients were included. The probit model showed a significant relationship between the HR-CTV D90 value and the local control probability, p < 0.0001. The D90 corresponding to a probability of 90% local control was 83.7 GyEQD2,10 (80.6-87.8 GyEQD2,10). Of the 33 studies included in our analysis, eight studies, including 1172 patients, reported the IR-CTV D90 value, ranging from 59.1 GyEQD2,10 to 72.3 GyEQD2,10. The probit model also showed a significant relationship between the IR-CTV D90 value and the local control probability, p = 0.0464. The 60 GyEQD2,10 for IR-CTV D90 corresponded to an 86.1% local control probability (82.0%-89.8%). CONCLUSIONS A significant dependence of local control on HR-CTV D90 and IR-CTV D90 was found. A tumor control probability of >90% can be expected at doses >84 GyEQD2,10 and 69 GyEQD2,10, respectively, based on an updated meta-regression analysis.
