The aim of the study was to systematize and summarize the current available data on ruxolitinib use in patients with myelofibrosis (MF) prior to allogeneic hematopoietic stem cell transplantation (allo-HSCT) to improve its results. The review includes data from foreign and domestic articles found in the PubMed and elibrary.ru databases describing the results of the use of ruxolitinib in patients with MF prior to allo-HSCT, including clinical cases, original scientific studies and reviews. It is reported that ruxolitinib therapy is safe, reduces mortality in the early post-transplantation period, reduces the incidence of acute and chronic graft-versus-host disease, and decreases the frequency of relapses. Clinical improvement with ruxolitinib therapy prior to allo-HSCT can be considered a prognostically favorable factor.
