- Purpose To assess the effect of erythropoietin (EPO) plus granulocyte-colony stimulating factor (G-CSF) treatment on survival and leukemic transformation in myelodysplastic syndrome (MDS).Patients and Methods We compared the long-term outcome of patients with MDS treated with EPO plus G-CSF (n = 121) with untreated patients (n = 237) with MDS using multivariate Cox regression with delayed entry, for the first time adjusting for all major prognostic variables (WHO classification, karyotype, cytopenias, level of transfusion-need, age, and sex).Results The erythroid response rate to EPO plus G-CSF was 39%, and the median response duration 23 months (range, 3 to 116+). In the multivariate analysis, treatment was associated with improved overall survival (hazard ratio, 0.61; 95% CI, 0.44 to 0.83; P = .002). Interestingly, this positive association was primarily observed in patients requiring fewer than 2 units of RBCs per month. Treatment was not linked to the rate of acute myeloid leukemia in any defined subgroup, including patients with an increase of marrow blasts or an unfavorable karyotype.Conclusion The inherent risk of leukemic evolution in MDS makes the current investigation highly relevant, in light of the recent reports of potential negative effects of EPO treatment on outcome in patients with cancer. We conclude that treatment of anemia in MDS with EPO plus G-CSF may have a positive impact on outcome in patients with no or low transfusion need, while not affecting the risk of leukemic transformation.

- The Swedish national guidelines for treatment of acute myeloid leukemia (AML) recommend analysis of measurable residual disease (MRD) by multiparameter flow cytometry (MFC) in bone marrow in the routine clinical setting. The Swedish AML registry contains such MRD data in AML patients diagnosed 2011–2019. Of 327 patients with AML (non-APL) with MRD-results reported in complete remission after two courses of intensive chemotherapy 229 were MRD-negative (70%), as defined by <0.1% cells with leukemia-associated immunophenotype in the bone marrow. MRD-results were reported to clinicians in real time. Multivariate statistical analysis adjusted for known established risk factors did not indicate an association between MFC-MRD and overall survival (HR: 1.00 [95% CI 0.61, 1.63]) with a median follow-up of 2.7 years. Knowledge of the importance of MRD status by clinicians and individualized decisions could have ameliorated the effects of MRD as an independent prognostic factor of overall survival. © 2021 The Author(s).
