Objective:
To evaluate whether a citation advantage exists for open access (OA) publications in gynecologic oncology.
Method:
A cross-sectional study of research and review articles published in the International Journal of Gynecological Cancer (IJGC) and in Gynecologic Oncology during 1980-2022. Bibliometric measures were compared between OA publications and non-OA publications. The role of authors in low/middle-income countries was assessed. We analyzed article characteristics associated with a high citations per year (CPY) score.
Results:
Overall, 18 515 articles were included, of which 2398 (13.0%) articles were published OA. The rate of OA has increased since 2007. During 2018-2022, the average proportion of articles published OA was 34.0% (range 28.5%-41.4%). OA articles had higher CPY (median (IQR), 3.0 (1.5-5.3) vs 1.3 (0.6-2.7), p<0.001). There was a strong positive correlation between OA proportion and impact factor; IJGC - r(23)=0.90, p<0.001, Gynecologic Oncology - r(23)=0.89, p<0.001. Articles by authors from low/middle-income countries were less common among OA articles than among non-OA articles (5.5% vs 10.7%, p<0.001). Articles by authors from low/middle-income countries were less common in the high CPY group than for articles without a high CPY score (8.0% vs 10.2%, p=0.003). The following article characteristics were found to be independently associated with a high CPY: publication after 2007, (adjusted odds ratio (aOR)=4.9, 95% CI 4.3 to 5.7), research funding reported (aOR=1.6, 95% CI 1.4 to 1.8), and being published OA (aOR=1.5, 95% CI 1.3-1.7). Articles written by authors in Central/South America or Asia had lower odds of having high CPY (Central/South America, aOR=0.5, 95% CI 0.3 to 0.8; Asia, aOR=0.6, 95% CI 0.5 to 0.7).
Conclusion:
OA articles have a higher CPY, with a strong positive correlation between OA proportion and impact factor. OA publishing has increased since 2007, but articles written by authors in low/middle-income countries are under-represented among OA publications.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
