Aim: A comprehensive scientometric analysis produced in hematology and oncology on coronavirus disease-2019 (COVID-19) research is lacking. This study presents a detailed analysis of COVID-19 related hematology and oncology literature. Methods: The Web of Science (WoS) Core Collection was used for data collection. All published documents between 2020 and 2021 were included. The data exported from WoS enabled the extensive details of COVID-19 related literature in the hematology and oncology categories, including countries, institutions, authors, citations, and keywords. Scientometric interaction visualization of keywords and countries, and published journal co-authorships were created with free software. Worldwide participation of the countries in COVID-19 related hematology and oncology literature were shown by a graphic. Results: The search question displayed 4761 documents. The leading type of document was original articles (34.4%). The United States of America was the number one country, publishing 32.6% of all documents on COVID-19 related hematology and oncology research, followed by Italy, the United Kingdom, China, and France. Huazhong University of Science and Technology was the most contributing institution in the literature (2.8%), followed by Harvard Medical School and Memorial Sloan Kettering Cancer Center. The journal Blood has published the most documents about this field. The average citations per item was 7.2. The most used keywords over this period were “COVID-19,” “SARS-CoV-2,” “coronavirus,” and “cancer”. Conclusion: The results of the present study may assist health professionals interested in this field to better figure out the current trends in COVID-19 related hematology and oncology research worldwide, and it can provide them to reach a more accurate information in a shorter time.
