ABSTRACT
OBJECTIVE@#To explore the prognostic factors of patients with multiple myeloma (MM) based on nutritional status.@*METHODS@#The Controlling Nutritional Status (CONUT) score and clinical parameters at diagnosis of 203 newly diagnosed MM patients hospitalized in the department of hematology, Wuxi People's Hospital from January 1, 2007 to June 30, 2019 were analyzed retrospectively. The best cut-off value was determined by ROC curve, and the patients were divided into high CONUT group (>6.5 points) and low CONUT group (≤6.5 points); through COX regression multivariate analysis of overall survival (OS) time, CONUT, ISS stage, LDH and treatment response were selected for multiparameter prognostic stratification.@*RESULTS@#The OS of MM patients in high CONUT group was shorter. The low-risk group (≤2 points) of the multiparameter risk stratification had longer OS time and progression-free survival (PFS) time compared with the high-risk group (>2 points), and it was also effective for different age or karyotype subgroups, new drug groups containing bortezomib and transplant-ineligible subgroup.@*CONCLUSION@#The risk stratification of MM patients based on CONUT, ISS stage, LDH and treatment response is worthy of clinical application.

At present, multiple myeloma (MM) still can not be cured, so it is particularly important to study the prognostic factors of MM. Recently, based on the characteristics of tumor or host, the complete disease staging systems, such as Mayor mSMART and frailty scoring system have been updated. Other independent prognostic factors, such as minimal residual disease, circulating tumor DNA, red blood cell distribution width, lymphocyte ratio and thymidine kinase 1 are of great value in evaluating the prognosis of MM from different perspectives. The comprehensive study about these prognostic factors is helpful to identify patients with high-risk MM to guide treatment and hopefully improves the quality of life of patients. In this review, the latest research progress of prognostic factors for MM is summarized briefly.
