WBC Count and WBC to Hb Ratio Could Predict Short-Term Recurrence Rate in Multiple Myeloma Patients Underwent Autologous Stem Cell Transplantation

Multiple myeloma (MM) is a hematologic malignancy with a variable clinical course. We investigated the prognostic role of routine laboratory factors including CBC indices and serum vitamin D levels to predict MM recurrence after receiving an autologous stem cell transplant (ASCT). 29 patients were enrolled. Before ASCT, demographic data and CBC, serum Cr, and Vit D levels were obtained. Patients underwent bone marrow aspiration (BMA) and biopsy (BMB) before ASCT and pretransplant plasma cell counts were also evaluated. Patients were followed for 6 months and BMA and biopsy were done in the 3rd and 6th month of the follow-up to detect recurrence. Overall, 9 patients were reported to have recurrence. The patient's WBC count mean was 13.3±11.6. WBC count was lower in patients with overall recurrence (P=0.005). Patients were divided into 2 groups according to WBC count (
