Current status and hotspots evolution in myeloproliferative neoplasm: a bibliometric analysis from 2001 to 2022.

OBJECTIVE: In the last 20 years, the field of myeloproliferative neoplasm (MPN) has changed dramatically. This study aims to provide new ideas for the scientific research of MPN by systematically combing the literature.

MATERIALS AND METHODS: CiteSpace and VOSviewer were used to carry out a bibliometric analysis of MPN papers to visualize the development process, research hotspots, and cutting-edge trends in clinical practice, mechanisms, and management strategies related to MPN.

RESULTS: 1,099 authors from 736 institutions in 113 countries/regions published 11,922 papers in 1,807 academic journals. The United States and Italy were in the leading positions in this research field. Mayo Clinic is the institution with the largest number of publications. Only a few countries and institutions have shown active cooperation. Ayalew Tefferi and Ruben A. Mesa are outstanding contributors to the field. Blood and Leukemia are considered influential journals based on publications and citations. In this field, the research of MPN mainly focuses on the occurrence and progress mechanism of MPN, the clinical significance of non-driving gene mutation, optimization of primary and secondary thromboprophylaxis, clinical research of long-acting interferon and JAK2 inhibitors, and exploration of better therapies for myelofibrosis (primary and secondary) and post-MPN acute myeloid leukemia (AML).

CONCLUSIONS: The research is in a stage of rapid development. The collaboration between different institutions or countries (regions) still has room to grow. The hotspot analysis shows that the research of MPN mainly focuses on gene mutation, thrombosis, new drug applications, disease progression, etc.
