The independent association of mean platelet volume with overall survival in multiple myeloma

چکیده
We retrospectively analyzed the association between mean platelet volume (MPV) and prognosis in 62 newly diagnosed multiple myeloma (MM) patients. The associations between MPV and clinical characteristics were assessed. The log-rank test and the Cox proportional hazards model were used to evaluate the effect of MPV on survival. A MPV value of 8.50 fl was considered to be the optimal cut-off value for prognosis. MPV was associated with IgA isotype (P=0.012), serum creatinine concentration > 176.8 μmol/L (P=0.025) and IgH rearrangement (P=0.008). The log-rank test demonstrated that patients with low MPV experienced a shorter overall survival (OS) (P=0.0397). The multivariate analysis demonstrated that low MPV was an independent prognostic factor for OS [hazard ratio (HR)=2.44, P=0.026]. Therefore, we demonstrated that low MPV predicted an unfavorable prognosis in patients with MM.
