Deutsche Studiengruppe Multiples Myelom (Dsmm) Evaluation Of The Risk Of Relapse And Survival Using A Conditional Survival Approach In 815 Mm Patients With Extensive, Complete And Repeated And Long-Term Follow-Up

Introduction: CS describes probabilities of surviving t additional years (ys) given patients (pts) survived s ys, and generates information, how prognosis evolves over time. We have previously adopted this approach in MM pts with complete follow-up, which is mandatory for CS calculations (Hieke et al., Clin Cancer Res 2015). The results were refined here by accumulating time-dependent MM- and pt-specific information, including cytogenetics and response to treatment over time, again with extensive, complete and repeated long-term follow-up.
