Proliferative responses of peripheral blood mononuclear cells to phytohemagglutinin during chemotherapy and after PBPC infusions as described in “Materials and methods.”

Net proliferative responses as measured in cpm are expressed as a ratio compared with net proliferative response of PBMCs from a simultaneously studied healthy donor. Pre-rx n = 13, Cy6 n = 15, 1 month n = 9, 3 months n = 9, 6 months n = 3, 9 months n = 4, 12 months n = 4, and 24 months n = 2.
