Proliferative rate of neoplastic B cells in individual B-CLPD patients in comparison with their normal counterparts. The range of S + G2/M-phase cells for the corresponding normal B-cell counterpart is shown as a gray box, and the dotted line corresponds to normal median values. *P < .05 for B-CLL versus normal mature bone marrow (BM) CD45^hiCD19⁺ B cells and CD20⁺CD23⁺ peripheral blood (PB) B lymphocytes; **P = .01 for MCL LN samples versus CD38^loCD20⁺ reactive LN B lymphocytes; ***P < .001 for FL versus CD38⁺CD20^hi reactive LN B lymphocytes; and ****P < .05 for LPL/WM versus normal BM and lymph node (LN) plasma cells. B-CLL indicates B-cell chronic lymphocytic leukemia; HCL, hairy cell leukemia; MCL, mantle-cell lymphoma; SMZL, splenic marginal zone B-cell lymphoma; MALT, mucosa-associated lymphoid tissue lymphoma; FL, follicular lymphoma; DLBCL, diffuse large B-cell lymphoma; BL, Burkitt lymphoma; and LPL/WM, lymphoplasmacytic lymphoma/Waldenström macroglobulinemia.
