In this regard, the aim of this study is to establish and validate a machine learning\u2013based predictive model for survival after allogeneic HCT in patients with hematologic malignancies.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n Data from 1470 patients with hematologic malignancies who underwent allogeneic HCT between December 1993 and June 2020 at Asan Medical Center, Seoul, South Korea, were retrospectively analyzed. Using the gradient boosting machine algorithm, we evaluated a model predicting the 5-year posttransplantation survival through 10-fold cross-validation.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n The prediction model showed good performance with a mean area under the receiver operating characteristic curve of 0.788 (SD 0.03). Furthermore, we developed a risk score predicting probabilities of posttransplantation survival in 294 randomly selected patients, and an agreement between the estimated predicted and observed risks of overall death, nonrelapse mortality, and relapse incidence was observed according to the risk score. Additionally, the calculated score demonstrated the possibility of predicting survival according to the different transplantation-related factors, with the visualization of the importance of each variable.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n We developed a machine learning\u2013based model for predicting long-term survival after allogeneic HCT in patients with hematologic malignancies. Our model provides a method for making decisions regarding patient and donor candidates or selecting transplantation-related resources, such as conditioning regimens.<\/jats:p>\n
