Abstract:
Objective:To explore the clinical and pathological features of EBV-positive diffuse large B cell lymphoma (EBV +DLBCL) and to analyze the prognostic significance of CD30 expression in this entity. Methods:A retrospective analysis was conducted from 34 cases of EBV +DLBCL and 198 cases of EBV -DLBCL diagnosed and treated at the First Affiliated Hospital of Nanjing Medical University, from January 2017 to June 2023. Based on CD30 expression, 34 patients with EBV +DLBCL were categorized into CD30-positive and CD30-negative groups. Fisher exact test and Kaplan-Meier survival curves were employed to analyze the relationship between CD30 expression and clinicopathological parameters as well as its prognostic implications. Chi-square tests were used to compare the clinicopathological features between EBV +DLBCL and EBV -DLBCL. Results:There were 19 males and 15 females with a median age of 69.5 (15-83) years in the EBV +DLBCL group. Compared with EBV -DLBCL, EBV +DLBCL was more likely to present with clinical features such as B symptoms ( χ2=23.818, P<0.001), Ann Arbor stage Ⅲ-Ⅳ ( χ2=8.540, P=0.003), ECOG (Eastern Cooperative Oncology Group Performance Status) score 2-4 ( χ2=6.722, P=0.010), IPI score 3-5 ( χ2=9.953, P=0.002), and involvement of more than one extranodal site ( χ2=6.825, P=0.009). Additionally, EBV +DLBCL exhibited higher frequencies of elevated LDH ( χ2=4.307, P=0.038), CRP ( χ2=5.596, P=0.018), and β2-MG ( χ2=7.008, P=0.008) levels. Histopathologically, EBV +DLBCL was more commonly of the non-GCB subtype ( χ2=12.421, P<0.001), with higher frequencies of CD30-positive ( χ2=62.706, P<0.001),CD10-negative ( χ2=8.687, P=0.003),bcl-6-negative ( χ2=11.123, P<0.001), and bcl-2-negative ( χ2=22.779, P=0.003) expression. Using 20% as the positive threshold for CD30, the CD30-positive group had a higher proliferation index ( P=0.045). No significant differences were observed in overall survival between the two groups. Conclusions:EBV +DLBCL is more prevalent in the elderly and often exhibits aggressive clinical features. The expression of CD30 is not associated with the overall prognosis of EBV +DLBCL.
