The NPC patients with IgD + cells shows the better survival. (A) IgD + cells IHC staining images. (B) IgD- cells IHC staining images. (C) IgD + patients with NPC has the higher CD20 + density than the IgD- patients. (D) Distant metastasis-free survival in NPC patients with IgD positive or IgD negative. (E) Overall survival in NPC patients with IgD positive or IgD negative
