Therefore, the aim of this study is to investigate and compare the efficacy of filgrastim and lenograstim drug treatment in patients with neutropenia in a systematic review. Methods: This study is a systematic review study conducted in connection with the comparison of the effectiveness of filgrastim and lenograstim in neutropenic patients based on the search in Google scholar, PubMed, ScienceDirect, Irandoc, SID, Magiran databases in the time range of January 2000 to August 2023. This systematic review was based on the criteria of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, including systematic search of databases, organization of documents for review, selection of studies, information extraction and finally presentation of the final report. The keywords used for searching in this study were selected based on published primary studies and MESH, and after a detailed examination of the study questions, they were selected according to the PECO criteria. Results: 1099 articles were identified in the review of the investigated databases, and after removing duplicate articles, unrelated articles, as well as articles that did not have access to their full text or did not have the required information, eight studies were the final phase, and were checked. Out of the eight selected articles, three articles declared the effectiveness of lenograstim more than filgrastim. Two articles mentioned the greater effect of filgrastim and three articles published in recent years declared the effect of two drugs to be the same. Among these articles, the studies that considered the drug dosage to be the same in the investigated groups and the studies that had a larger statistical population in order to generalize to the society are more important. Conclusion: According to studies conducted in recent years, both filgrastim and lenograstim recombinant drugs have the same effectiveness in the treatment of neutropenia.
