Abstract

Purpose: The purpose of this bibliometric study was to point out the emergence and development of immunotherapy in cancer treatment and shifting tendencies on this field in the last years. We aimed to create an ease of access for the researchers of this dynamic field.

Methods: Cancer immunotherapy as a search term was queried into Thomson Reuter's Web of Science database of 2019 to list all the articles about this term. The top 100 cited articles were analyzed by topic, journal, author, year, institution, level of evidence, adjusted citation index and also the correlations between citation, adjusted citation index, impact factor and length of time since publication.
