Immunophenotypes of 52 cases of diffuse large B-cell lymphoma. Diagram demonstrating the relative frequencies of germinal center (GC) and Hans et al²⁵ algorithm marker immunophenotypes in 52 cases of diffuse large B-cell lymphoma. The percentage of cases within the Hans-defined GC and non-GC (NGC) groups is given under each column. White indicates marker positivity while black indicates the marker was negative. KLHL6 was considered positive if at least 5% of the cells stained, as described in the Materials and Methods section, whereas cutoffs of 30% were used for the other antibodies, for consistency with the original Hans et al²⁵ model.
