چکیده
PURPOSE The risk factors for venous thromboembolism (VTE) in diffuse large B-cell lymphoma (DLBCL) are not clear although thrombosis can be associated with host status, tumor burden, and inflammatory activity. We assessed the effect of those factors on VTE in a cross-sectional study of patients enrolled in a prospective cohort study. MATERIALS AND METHODS We analyzed the occurrence of VTE in 322 patients with newly diagnosed DLBCL who received rituximab with cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) between 2008 and 2011. Serum levels of inflammatory cytokines were measured from serum samples archived at diagnosis. RESULTS With a median follow-up duration of 41.9 months, VTE was documented in 34 patients (10.6%). A comparison of baseline characteristics indicated the group with VTE had higher percentage of old age, stage III/IV and extranodal involvements than the group without VTE (p < 0.05). Thus, the International Prognostic Index was significantly associated with VTE, but the Khorana score was not. A univariate competing risk factor analysis for VTE revealed that increased levels of inflammatory cytokines such as interleukin (IL)-6 and IL-10 were also associated with VTE (p < 0.05) in addition to host and tumor burden. However, a multivariate analysis showed that two host factors including age (≥ 60 years) and poor performance were independent risk factors for VTE. CONCLUSION Among potential risk factors for VTE including tumor burden and inflammatory activity, age and performance status had a strong impact on the occurrence of VTE in patients with DLBCL who received R-CHOP.

Background: Chronic lymphocytic leukemia (CLL) can transform into fast growing lymphoma for diffuse large B-cell lymphoma (DLBCL) called Richter's syndrome (RS), which is commonly related to an existence of large B-cells with equal or larger size than macrophage nuclei or more than twice those of normal lymphocyte. We conducted a systematic review of the existing literature to assess the clinic...
