摘　　要：BACKGROUND Extramedullary multiple myeloma(MM)(EMM)is a rare and aggressive subentity of MM that can be present at diagnosis or develop anytime during the disease course.There is a paucity of data on the clinical characteristics and overall epidemiology of EMM.Furthermore,there is a scarcity of data on how the interaction of age and gender influences the survival of EMM.AIM To evaluate the clinical characteristics of patients with EMM over the past 2 decades and to identify epidemiologic characteristics that may impact overall prognosis.METHODS A total of 858 patients diagnosed with EMM,between 2000 and 2017,were ultimately enrolled in our study by retrieving the Surveillance,Epidemiology,and End Results database.We analyzed demographics,clinical characteristics,and overall mortality(OM)as well as cancer-specific mortality(CSM)of EMM.Variables with a P value<0.1 in the univariate Cox regression were incorporated into the multivariate Cox model to determine the independent prognostic factors,with a hazard ratio(HR)of greater than 1 representing adverse prognostic factors.RESULTS From a sample of 858 EMM,the male gender(63.25%),age range 60-79 years(51.05%),and non-Hispanic whites(66.78%)were the most represented.Central Nervous System and the vertebral column was the most affected site(33.10%).Crude analysis revealed higher OM in the age group 80+[HR=6.951,95%confidence interval(95%CI):3.299-14.647,P=0],Non-Hispanic Black population(HR=1.339,95%CI:1.02-1.759,P=0.036),Bones not otherwise specified(NOS)(HR=1.74,95%CI:1.043-2.902,P=0.034),and widowed individuals(HR=2.107,95%CI:1.511-2.938,P=0).Skin involvement(HR=0.241,95%CI:0.06-0.974,P=0.046)and a yearly income of$75000+(HR=0.259,95%CI:0.125-0.538,P=0)had the lowest OM in the crude analysis.Crude analysis revealed higher CSM in the age group 80+,Non-Hispanic Black,Bones NOS,and widowed.Multivariate cox proportional hazard regression analyses only revealed higher OM in the age group 80+(HR=9.792,95%CI:4.403-21.774,P=0)and widowed individuals(HR=1.609,95%CI:1.101-2.3
