Proliferative activity of myeloma cells determined by Ki-67 antibody: Biological and clinical significance
In this study we analyzed proliferative activity of myeloma cells and a possible correlation with selected clinical data, histological features and survival in 59 patients with newly diagnosed multiple myeloma (27 females and 32 males, mean age 62 years). Imunohistochemical method was applied using...
