FIGURE 1.

Association between pre‐Ld cytokine levels and best response after Ld therapy. Patients were classified as good responders (complete response [CR] + very good partial response [VGPR] + partial response [PR]) or poor responders (minimal response [MR] + stable disease [SD] + progressive disease [PD]). The horizontal red bars represented the median values of the levels of each group. (A, B) The expression levels of IL‐18 and M‐CSF were significantly higher in poor responders to Ld therapy. (C) The concentration of PDGF‐BB was significantly lower in poor responders.
