Abstract
BACKGROUND: Many articles have been published on pituitary adenomas. Bibliometric analyses are helpful for determining the most impactful studies within a field. OBJECTIVE: To identify the top 100 most-cited articles on pituitary adenomas using the bibliometric analysis method. METHODS: We searched the Thomson Reuters Web of Science on March 31, 2018. Articles were listed in descending order by the total citation (TC) number, and the most-cited articles on pituitary adenomas were identified and analyzed. RESULTS: The most-cited articles were published between 1970 and 2014, with 1999 as the most prolific year. Growth hormone-secreting pituitary adenoma was the most commonly studied tumor subtype (43%), and in clinical studies, treatment options and follow-up were the most important research focuses (62%). The average number of TCs was 326, and the average number of annual citations (ACs) was 17. More review articles were published in the last decade, and the average number of ACs was higher for this decade than for previous decades. Twenty-one articles were recognized as citation Ccassics, with a TC number >400. Twenty-five journals published the top 100 works; Journal of Clinical Endocrinology and Metabolism published the most articles (25%). The most articles (43%) were published in the United States. S. Melmed wrote the greatest number of publications (14%). Departments of medicine (32%) and endocrinology (32%) contributed to the largest number of articles. CONCLUSIONS: This study identified the research focuses and trends regarding pituitary adenoma and provides key references for investigators in guiding future pituitary adenoma research.
