Distribution of BCL2, BCL6, CD10, CD5, HLA-DR, Ki67, and MUM1 scoring results when using the previously validated methods in the 347 r-CHOP patients. Numbers on the bar graph correspond to the percentage of patients in each category. The categories are numbered from 1-5. For BCL2 and MUM1: 1 = 0%-5%, 2 = 5%-25%, 3 = 26%-50%, 4 = 51%-75%, and 5 = 76%-100%. For BCL6: 1 = no staining, 2 = weak/variable weak staining, and 3 = strong/variable strong staining. For CD10 and HLA-DR: 1 = negative and 2 = positive. For CD5: 1 = no staining, 2 = 1%-75% staining, and 3 = 76%-100% staining. For Ki67: 1 = 0%-25% staining, 2 = 26%-50% staining, 3 = 51%-75% staining, and 4 = 76%-100% staining. The number of r-CHOP patients scored for BCL2, BCL6, CD10, CD5, HLA-DR, Ki67, and MUM1 are 326, 212, 327, 333, 329, 239, and 293, respectively.
