Global Research Productivity of Post-Transplant Lymphoproliferative Disorder: A Bibliometric Study

Abstract

Introduction: Post-transplant lymphoproliferative diseases (PTLD) are a heterogeneous collection of neoplasms that occur after solid organ transplants (SOT). In the past 20 years, there has been a rise in PTLD research. This study aims to investigate the global research output and interest regarding PTLD using a bibliometric approach.

Method: On November 28, 2022, the Web of Science Core Collection documents on PTLD published between 2000 and 2022 were collected and analyzed using bibliometric techniques. The VOSviewer application was utilized to visualize the annual number of publications, authors, organizations, countries, published journals, citations, and most occurring keywords.

Results: A total of 2,814 documents were retrieved, and a screening process included 1809 documents. The total number of citations was 45239, and the average number per item was 25. Most articles (n = 747) and citations (n = 25,740) were produced in the United States. Based on citations, most of the top 10 institutions that contributed were in the United States of America. The University of Pittsburgh topped the list with 2,700 citations and 64 articles. The vast majority of articles were published in Pediatric Transplantation (n = 147), Transplantation (n = 124), and the American Journal of Transplantation (n = 98). Transplantation has received the most citations, 6499, followed by the American Journal of Transplantation with 5958 citations and Blood with 4107 citations.

Conclusion: With ongoing debates over optimal classification, EBV involvement, and treatment, this topic has received significant interest from researchers in recent years. Our results can be used as a guide for future research in the field and as a framework for a more in- depth look at the scientific progress of PTLD.
