From patient centered risk factors to comprehensive prognostic models: A suggested framework for outcome prediction in umbilical cord blood transplantation

Prospectively identifying patients who will gain maximal benefit from umbilical cord blood transplantation (UCBT) with minimal risk is a desirable unmet need. A complex network of parameters related to patient, disease, donor, and procedure all come into play. We review the prognostic role of patientrelated risk factors in adults undergoing UCBT. Furthermore, since comprehensive prognostic models are lacking in UCBT, we suggest a framework for integrating patients' features in the development of prediction models for UCBT outcomes. Such models could contribute to patient selection, optimization of the various modifiable features in the process of UCBT, analysis of retrospective data, and design of interventions.
