Abstract
Introduction: Extramedullary involvement in multiple myeloma represents aggressive disease, with clinical stratification of primary extramedullary disease (EMD) remaining a challenge. In this study, we aimed to develop a credible nomogram utilizing routine laboratory variables to predict individual survival for primary EMD patients.
Methods: We retrospectively analyzed a cohort of 60 primary EMD patients, from January 2006 to December 2022. Independent risk factors were identified and subsequently incorporated to generate a nomogram using the Cox proportional hazard regression model. Then, we classified patients into two risk groups based on the nomogram model risk score and compared their survival time using the Kaplan-Meier method.
Results: After a median follow-up of 25.4 months, the median progression-free survival (PFS) of primary EMD patients was 29.4 months. Three independent prognostic factors, namely Ki67, endothelial activation stress index (EASIX), and monocyte count, were identified and subsequently incorporated to generate a nomogram using the Cox proportional hazard regression model. Nomogram performance was assessed using various metrics. Then, we classified patients into two risk groups based on the nomogram model risk score, and the Kaplan-Meier curve showed that the median PFS was significantly longer in the low-risk group compared to the high-risk group (37.1 months versus 2.6 months, p < 0.001).
Conclusion: A predictive nomogram was developed and validated to evaluate the outcome of primary EMD patients.
期刊介绍:
''Acta Haematologica'' is a well-established and internationally recognized clinically-oriented journal featuring balanced, wide-ranging coverage of current hematology research. A wealth of information on such problems as anemia, leukemia, lymphoma, multiple myeloma, hereditary disorders, blood coagulation, growth factors, hematopoiesis and differentiation is contained in first-rate basic and clinical papers some of which are accompanied by editorial comments by eminent experts. These are supplemented by short state-of-the-art communications, reviews and correspondence as well as occasional special issues devoted to ‘hot topics’ in hematology. These will keep the practicing hematologist well informed of the new developments in the field.
