Clinical characteristics and prognostic factors of elderly multiple myeloma / 中国基层医药

ABSTRACT

Objective To investigate the clinical characteristics of elderly patients with multiple myeloma and their prognostic factors.Methods 100 multiple myeloma patients with age≥ 60 years and 100 multiple myeloma patients with age <60 years who admitted in our hospital from December 2007 to December 2015 were collected as research subjects.100 patients with age ≥60 years were divided into elderly multiple myeloma group,100 cases with aged <60 years were divided into non -elderly multiple myeloma group.The clinical data and laboratory results of two groups were compared,the prognosis factors in elderly patients with multiple myeloma were analyzed.Results The incidence rate of ISS stage Ⅰ -Ⅱ in elderly multiple myeloma group (45.0%)was lower than non -elderly multiple myeloma group (60.0%),the incidence rate of stage Ⅲ was higher than non -elderly multiple myeloma group (χ2 =4.511,P <0.05).The infection incidence of elderly multiple myeloma group(30.0%)was higher than non -elderly multiple myeloma group(15.0%)(χ2 =10.452,P <0.05 ).The hemoglobin,serum albumin contents of elderly multiple myeloma group [(83.7 ±19.8)g/L,(27.89 ±6.87)g/L]were less than non -elderly multiple myeloma group[(92.1 ±22.5)g/L,(33.15 ±7.69)g/L](t =4.297,4.426,all P <0.05).The calcium content,the propor-tion of bone marrow plasma cells,serum creatinine and blood β-microspheres protein levels of elderly multiple mye-loma group [(2.51 ±0.41)mmol/L,(39.43 ±18.64)%,(182.24 ±125.47)μmol/L,(9.02 ±6.24)mg/L]were higher than non -elderly multiple myeloma group [(2.36 ±0.48)mmol/L,(37.45 ±19.86)%,(143.25 ± 116.43)μmol/L,(5.87 ±3.41)mg/L](t =5.945,4.196,4.375,4.264,all P <0.05).The median survival time of elderly multiple myeloma patients were significantly correlated with the patients'age,the proportion of plasma cells in bone marrow,blood β2 -microglobulin,albumin,and ISS staging (χ2 =4.125,3.254,8.542,5.748,9.244,all P <0.05).Conclusion The condition of elderly myeloma patients is more serious,age,proportion of plasma cells in bone marrow,blood β2 -microglobulin,albumin and ISS stage affect myeloma patients prognosis.
