This paper presents a bibliometric study on blood cancers, considering publications distributed from 2012 to 2021. The study focuses on the literature available in the MEDLINE database, concealed within PubMed. A total of 32,750 documents on ‘Blood cancers’ were identified in the MEDLINE data covered by PubMed, with the highest number of 4,429 documents distributed in 2020. The document types were categorised, revealing that 39.11% were journal articles, 26.32% were Research Support, Non-U.S. Gov’t and 19.72% were Reviews. In Zone-1, 61 journals scattered 4,384 documents, accounting for one-third of the overall output. Zone-2 comprised 424 journals scattering 4,805 documents, and Zone-3 included 1,906 journals scattering 3,620 documents as journal articles. This study identified a total of 485 significant journals within the field of blood cancers. The analysis revealed that 60.98% of documents had more than five authors, while only 0.29% had no authors. The average degree of collaboration reached 0.96. A period-wise examination of the degree of collaboration showed an increasing trend from 2012 (0.94) to 2020 (0.97). The study suggests a high level of collaborative research in the field of blood cancers. [ABSTRACT FROM AUTHOR]
