It has been suggested that mean platelet volume (MPV) is associated with the risk of venous thromboembolism (VTE) and increased mortality in patients with cancer. We evaluated the association of MPV with VTE and mortality in patients treated for diffuse large B-cell lymphoma (DLBCL). Retrospective analyses were performed on 184 adult patients (median age 59, 55% men), of whom 141 were newly diagnosed, and 43 had relapse/refractory DLBCL. During the observation period (median 499 days), 39 (21.2%) patients developed VTE. Thirty-nine patients died of various causes. In univariate analysis, only the MPV and the treatment line were associated with the occurrence of VTE. In multivariate analysis, MPV ≤10th percentile (odd ratio 1.81; 95% confidence interval 1.06-3.11, p = 0.03) and salvage therapy (odd ratio 2.46; 95% confidence interval 1.66-3.65, p < 0.001) remained significant factors for developing VTE. Other patient-related factors-age, gender, disease-related factors-stage, the International Prognostic Index score, DLBCL subclassification (the germinal centre type and the activated B-cell type), Ki-67 index and VTE risk assessment model failed to be prognostic for VTE. In a Kaplan-Meier analysis, patients with MPV >10th percentile had statistically significantly longer VTE-free survival than patients with lower MPV. In multivariable Cox regression analysis, MPV ≤10th percentile (hazard ratio 5.56, p < 0.001), male gender, age, Ki-67 index, high or high-intermediate International Prognostic Index and VTE development (hazard ratio 7.81, p = 0.029) all significantly correlated with the risk of mortality. The probability of survival was higher in patients with MPV >10th percentile. In conclusion, our results suggest that the pre-chemotherapy MPV value is a cheap and available parameter that may be a useful prognostic marker for a significant risk of VTE and inferior survival rates in patients with DLBCL.

We retrospectively analyzed long-term disease outcome of 350 elderly Hodgkin Lymphoma (eHL) patients treated with ABVD/ABVD-like regimen enrolled in the PLRG-R9 study between 2001 and 2013 in Poland. Complete remission was reported for 73% of early (ES) and 61% advanced stage (AS) patients. Nine (10%) ES and 56 (20%) AS patients have died. With the median follow-up of 36 (1-190) months, 3-year EFS and OS was 0.74 (95%CI: 0.63-0.85) and 0.90 (95%CI: 0.82-0.98) for ES; 0.51 (95%CI: 0.44-0.57), and 0.81 (95%CI: 0.75-0.86) for AS patients, respectively. For ES patients, Cox regression revealed ECOG <2 and age >70 as predictive for inferior OS and EFS. For AS patients, the most predictive for OS was the presence of cardiovascular disorders (CVD) (p = .00044), while for EFS four factors were significantly associated with a poor outcome: ECOG< 2, age >70 years, CVD and extranodal disease. In conclusion, CVD significantly impacts outcomes of ABVD-treated advanced eHL patients.

B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) is the most common form of leukemia affecting adults in Europe and North America. Large B-cell lymphoma known as Richter’s syndrome (RS) may develop approximately in 3–15 % patients. Furthermore, other hematological malignancies may also occur as RS variants, among them—Hodgkin lymphoma (HL). CLL/SLL transformation into HL is observed in about 0.5 % of patients, and till now, fewer than 100 cases have been reported in the medical literature. We present two cases of HL transformation of CLL/SLL and review the previously published literature.
