ABSTRACT The refined disease risk index (DRI) is a powerful prognostic model based solely on the disease type and stage for predicting survival outcomes of various hematological malignancies


after allogeneic transplant. Here, we analyzed our series of 690 patients transplanted over the past 15 years, and showed that besides overall survival (OS), the refined DRI is also able to


segregate event-free survival and relapse mortality in our cohort of largely Southeast Asian patients with a long and complete follow-up. Stratification by refined DRI remains statistically


significant even when broken down by specific diseases each with a smaller number of patients, as well as for a small subset of patients younger than 18 years old, providing a robust model


for prognostication. Multivariable analysis shows that refined DRI, age, year of transplant and donor type are independent risk factors for OS. We further demonstrated here that


prognostication for a given patient with a specific disease can be made more discriminating by integrating independent risk factors such as age and donor type with the refined DRI. The


future development of prognostic system incorporating the refined DRI with patient- and transplant-related risk factors will provide a more precise estimate of transplant outcome. Access
