An Overview of Oncology Researches in Iran: A Scientometric Approach (1974 - February 2019)

With the growing rate of tumors, cancer has become one of the most important health concerns in Iran. The urgency with which Iranian researchers and health professionals address this challenge leads to a load of scientific materials. To reveal gaps in produced knowledge and suggest future research directions, applying well-validated scientometric tools, we assessed the trends of Iranian published scientific articles and citations in the field of oncology. The inclusion criteria consisted of all oncology-related articles that were data-based, and peer-reviewed; with at least an abstract published in English; and authored by at least one researcher affiliated with Iranian institutions. Amongst 5063525 oncology research records indexed in at least one of PubMed, Scopus, or Web of Science Core Collection (WoS) from the start to February 2019, Iranian researches accounted for about 24867 (0.49%). Published articles on all cancers by Iranian researchers had a sharp continuously ascending trend, with the same pattern for citations received. Some important topics such as complementary and alternative medicine (CAM) therapies have been missing and some such as diagnostic and pharmaceutical innovations have been less investigated. The most collaborative country was the United States, while no close collaboration was observed with China that was introduced as the most productive country in the field of oncology over the past decades. Despite the progressive trend in most oncology fields, some significant practical topics are still missing. Systematic reviews of produced theoretical innovations and translating them to functional knowledge can be of importance to fulfill the mentioned gaps.
