ABSTRACT
<p><b>OBJECTIVE</b>To analyze the subtypes of primary diffuse large B cell lymphoma of the central nervous system (CNS DLBCL) and to explore the relationship between the subtype classification and prognosis.</p><p><b>METHODS</b>Immunohistochemical staining was used to determine the expression of CD20, CD3, CD10, Bcl-6, Mum-1, CD5, Bcl-2, Ki-67, FOXP-1, GCET-1, BLIMP-1 and LMO-2 antigens on paraffin-embedded sections of 47 cases. Hans, Choi and Tally subtypes were classified, and univariate and multivariate analyses were used to elucidate the relationship between the subtypes and prognosis.</p><p><b>RESULTS</b>In the 47 cases, the expression of Bcl-2 in the tumor cells was 46.8%, CD10 4.3%, Bcl-6 70.2%, Mum-1 53.2%, GCET-1 36.2%, BLIMP-1 4.3%, FOXP-1 63.8% and LMO-2 19.2%. The positive rate of Ki-67 was 30% to 95%, with a median of 80%, of which 12 cases (25.5%) was > or = 90%. The Hans subtype classification showed 16 cases (34.0%) were of GCB type and 31 cases (66.0%) of non-GCB type. The Choi subtype classification showed 16 cases (34.0%) were of GCB type and 31 cases (66.0%) of ABC type. The Tally subtype classification showed 6 cases (12.8%) were of GCB type and 41 cases (87.2%) of non-GCB type.</p><p><b>CONCLUSIONS</b>The results of this study show that there is no significant correlation between the three subtypes and prognosis. The prognosis is correated with post-operative radiotherapy, chemotherapy and MTX therapy.</p>
