CD5+ diffuse large B-cell lymphoma has heterogeneous clinical features and poor prognosis: a single-center retrospective study in China.

ABSTRACT:

Objective

De novo CD5-positive (CD5+) diffuse large B-cell lymphoma (DLBCL) has different clinical characteristics compared with CD5-negative (CD5-) DLBCL. However, few studies have been reported in Chinese cohorts. We investigated the clinical features and prognosis of patients with CD5+ DLBCL and summarized the related literature.

Methods

Data from 245 patients with newly diagnosed DLBCL were retrospectively assessed.

Results

Thirty-one and 214 patients were diagnosed with CD5+ DLBCL or CD5- DLBCL, respectively. In the CD5+ DLBCL group, there were significantly higher proportions of patients with older age (≥60 years), International Prognostic Index (IPI) ≥3, Eastern Cooperative Oncology Group (ECOG) scores ≥ 2, bone marrow involvement, positive B-cell lymphoma 2 expression, and positive MYC expression. Survival analysis showed that CD5+ DLBCL had a markedly poorer 2-year progression-free survival than CD5- DLBCL (18.2% vs. 56.2%). Univariate analysis indicated that age ≥60 years, ECOG score ≥ 2, IPI ≥ 3, B symptoms, and no rituximab-based treatment were poor predictive factors for overall survival (OS). Multivariate analysis revealed that B symptoms and no rituximab-based treatment, but not positive CD5 expression, were independent factors for OS.

Conclusions

Patients with CD5+ DLBCL had heterogeneous clinical characteristics and poor survival. The development of more targeted and effective therapies is needed.

Project description:BackgroundWhile the epidemiologic association between hepatitis B virus (HBV) infection and diffuse large B-cell lymphoma (DLBCL) is established, little is known about the pathological characteristics and outcome of DLBCL arising in patients with HBV infection.MethodsWe retrospectively studied a cohort of 420 patients with DLBCL for the incidence of HBV infection, and the clinicopathologic features and prognostic factors in HBsAg-positive DLBCL patients in China, a hepatitis B endemic area.ResultsIn our study, 127 (30.2%) patients were HBsAg-positive. HBsAg-positive DLBCL displayed a younger median onset age (50 vs. 54 years, P = 0.002), more frequent involvement of the spleen (19.7% vs. 6.1%, P < 0.001), less frequent involvement of the small and large intestine (2.3% vs. 11.2%, P = 0.003), more advanced disease (stage III/IV: 56.7% vs. 45.1%, P = 0.028), and lower expression rate of MYC (49.1% vs. 66.7%, P = 0.026). The median follow-up time was 61.9 months. Univariate analysis showed that there was no significant difference in overall survival (OS) between HBsAg-negative and -positive DLBCL (P = 0.577). In the HBsAg-positive DLBCL subgroup, age older than 60 years, advanced disease, elevated lactate dehydrogenase (LDH), spleen involvement, B symptoms (fever, night sweats, weight loss), and double expressers of MYC and BCL2 had a significantly worse outcome, and patients treated with R-CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone) had a better prognosis. Multivariate analysis further confirmed that spleen involvement and rituximab use were independent prognostic factors in HBsAg-positive DLBCL patients.ConclusionsOur study indicates that HBsAg-positive DLBCL has unique clinicopathological features and independent prognostic factors. Moreover, under antiviral prophylaxis, the survival of DLBCL patients with HBV infections was comparable to that of HBV-negative patients, and the use of rituximab significantly improved OS in HBsAg-positive DLBCL patients.
