BCL6 and neoplasm: According to the Hans’ algorithm, patients were divided into two types: the germinal center B-cell (GCB) type (n = 40, CD10 + or CD10-BCL6 + MUM1-) and non-GCB type (n = 8, CD10-BCL6- or CD10-BCL6 + MUM1+), by semi-quantitatively scoring the fraction of tumor cells stained using a 30% threshold [16].
