Antiemetic prophylaxis in hematologic malignancies patients receiving conditioning protocols for hematopoietic stem cell transplantation: A study protocol for a system- atic review

Objective: Chemotherapy-induced nausea and vomiting continue to pose a significant challenge for patients un-dergoing hematopoietic stem cell transplantation. This study aims to synthesize available evidence on antiemetic prophylaxis regimens in patients with hematologic malignancies undergoing hematopoietic stem cell transplantation, in order to identify the best standard of care. Methods: A systematic review will be conducted using MEDLINE via PubMed, EMBASE, ClinicalTrials.gov., and Cochrane databases. Studies written in English, French, Italian or Spanish will be considered. After screening the literature according to the inclusion and exclusion criteria, two independent reviewers will extract data and assess the risk of bias in eligible articles. This protocol has been prepared according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) guidelines. This protocol is registered in the Prospective Register of Ongoing Systematic Reviews (PROSPERO) CRD42023406380. Discussion: Chemotherapy-induced nausea and vomiting is a debilitating side effect that presents a significant challenge for patients with hematologic malignancies. Despite the publication of various guidelines, none of them includes specific recommendations for each chemotherapy regimen. Therefore, analyzing the primary an-tiemetic prophylaxis regimens in patients with hematologic malignancies undergoing hematopoietic stem cell transplantation would be valuable in enhancing patients' quality of life.
