Key Points The neuronal marker UCH-L1 is induced in, and specifically augments the oncogene-induced transformation of, GCB cells. High levels of UCHL1 identify patients with GC DLBCL with an increased risk for poor outcomes.

Diffuse large B-cell lymphoma (DLBCL) can be molecularly subtyped as either germinal center B-cell (GCB) or non-GCB. The role of rituximab(R) in these two groups remains unclear. We studied 204 patients with de novo DLBCL (107 treated with first-line CHOP; 97 treated with first-line R-CHOP), patients being stratified into GCB and non-GCB on the basis of BCL-6, CD10, and MUM1 protein expression. The relationships between clinical characteristics, survival data, and immunophenotype (IHC) were studied. The 5-year overall survival (OS) in the CHOP and R-CHOP groups was 50.4% and 66.6% (P=0.031), respectively. GCB patients had a better 5-year OS than non-GCB patients whether treated with CHOP or not (65.0% versus 40.9%;P=0.011). In contrast, there is no difference in the 5-year OS for the GCB and non-GCB with R-CHOP (76.5% versus 61.3%;P=0.141). In non-GCB subtype, additional rituximab improved survival better than CHOP (61.3% versus 40.9%;P=0.0303). These results indicated that addition of rituximab to standard chemotherapy eliminates the prognostic value of IHC-defined GCB and non-GCB phenotypes in DLBCL by improving the prognostic value of non-GCB subtype of DLBCL.

Diffuse large B-cell lymphoma (DLBCL) is the most common form of Non-Hodgkin Lymphoma (NHL) in adults. Affecting nearly 7 out of every 100,000 people in the United States annually, this hematogenous neoplasm is known for its aggressiveness and rapid development. Being the most common NHL, it has been divided into several subgroups based on pathogenesis and treatment methods. In particular, subtypes such as germinal center, activated B-cell-like, and primary mediastinal diffuse large B-cell lymphomas  have been divided by their uniqueness of pathology at the cellular level. Knowing the numerous cytokines, inflammatory markers, and other microcellular processes that these lymphomas disrupt can help target an effective therapeutic at the disease.

The aim of this study is to explore the expression of osteopontin (OPN) and its relationship with prognostic factors and survival in diffuse large B cell lymphoma (DLBCL). A tissue microarray was performed for immunohistochemical evaluation. Contingency tables were analyzed for trends; chi-square test was used to determine differences between groups. Univariate and multivariate Cox proportional hazards-regression analyses were performed to evaluate the impact of prognostic factors on survival. Expression of OPN was observed in 28%. It was different in non-germinal center DLBCL (P=0.04). The mean overall survival (OS) was lower in patients with positive OPN expression (19.762; CI 95% 14.269-25.255) it was not significant (P=0.123). It is not possible to establish a clear relationship between the expression by immunohistochemistry of osteopontin and a poor prognosis but it would be important to complement the analysis with other techniques as PCR or NGS that allow us to assess the influence of the isoforms and post-translational modifications of OPN on the biological behavior of DLBCL. Our findings indicate that OPN expression could be associated with a more aggressive variant of lymphoma: non-germinal center DLBCL.
