Objective <p>Fumarate hydratase (FH) is a key enzyme in the Krebs cycle and cellular energy metabolism, playing a crucial role in tumorigenesis. It is considered a prognostic, diagnostic, and therapeutic target for many types of cancer. Therefore, FH is a popular scientific subject in cancer research. The current study aimed to identify cancer research in the WoS database and examine studies conducted on FH molecules using bibliometric indicators.</p> Methods <p>The keywords “fumarate hydratase” OR fumarase” AND “cancer OR tumor OR neoplasm” were used to search the WoS database. This search was performed using abstracts, titles, and keywords. The "Article" and “Review” options were used to access the data of papers published between 2002 and March 2024.</p> Results <p>A total of 840 publications (616 articles and 224 reviews) were published by the end of March 2024. Research output on FH and cancer has significantly increased recently, with the highest number of publications in 2020 (n = 69, 8.214%). The most commonly used language was English (n = 823, 97.976%), and the USA led in productivity, contributing 306 studies (36.429%). The University of Helsinki is the most productive affiliation with 138 published articles. The researcher who conducted most studies (n = 58, 6.904%) was also the most-cited author, with 1562 citations. In the current bibliometric study, “hereditary leiomyomatosis”, "mutations", and "renal-cell cancer" were frequently included in publications.</p> Conclusion <p>This bibliometric study provides a quantitative overview of FH research in oncology and presents the most recent FH status in cancer research.</p>
