Even though they are a key component of care, frequent transfusions are often associated with complications for patients. Due to the lack of durable response to treatment, many patients become transfusion-dependent during the course of their disease.3,21-24

Transfusion burden in patients with lower-risk MDS impacts survival7,*
Chart adapted from Sangerman MA, et al.7

Analysis of survival correlated with prospectively registered transfusion burden in 474 patients diagnosed with lower-risk MDS based on revised IPSS selection criteria at the Catalan Institute of Oncology of Barcelona between January 1992 and July 2018. Overall survival was measured in years since diagnosis. Longitudinal transfusion burden was calculated by dividing the cumulative total RBC units by the number of weeks between first transfusion and death. RBC transfusion burden was stratified according to 2018 IWG criteria, dividing patients into 3 categories: non-transfused (0-2 units/16 weeks), low transfusion burden (3-7 units/16 weeks), and high transfusion burden (>8 units/16 weeks).7
In a prospective, observational, single-center, European study of lower-risk MDS patients, high transfusion burden was found to predict low overall survival.7,*
Patients who achieve or maintain transfusion independence may live longer26,†
Mortality risk findings were based on a meta-analysis of 5 studies between January 2014 and May 2014, on the association between transfusion independence and OS in patients with MDS. Studies were included in the analysis if they had recruited adults aged >18 years with a confirmed diagnosis of MDS and had reported OS for transfusion-independent patients versus transfusion-dependent patients.26
