Disclaimer: This web tool is intended for research purposes only. This calculator is based on results from a CIBMTR analysis of HLA-haploidentical transplantation with PTCy for acute leukemia and myelodysplastic syndrome. It remains the responsibility of each medical professional to decide on the appropriate medical advice, diagnosis, and treatment for patients.


This tool predicts the probability of disease-free survival from attributes of a HSCT donor-recipient pair based on the research findings of HLA Informs Risk Predictions after Haploidentical Stem Cell Transplantation with Post-transplantation Cyclophosphamide (Fuchs E, McCurdy S, et al., 2021). This retrospective study of 1434 patients uses a Cox proportional hazards model to better understand the effects of HLA locus-specific risks following haploidentical transplantation using PTCy.
