Thrombosis is a common complication in cancer patients, with a substantial impact on morbidity and mortality. Diffuse large B-cell lymphoma (DLBCL) and other aggressive lymphomas carry a high venous thromboembolism (VTE) risk. Extracellular vesicles (EVs) have gained attention in recent research as a new potential biomarker for VTE development. To determine the profile and association of EVs with VTE in patients with DLBCL, we conducted a prospective cohort study on 62 patients diagnosed with DLBCL. A total of 11 patients (17.7%) developed VTE. The concentrations of platelet-derived EVs (PEVs), E-selectin+ EVs, P-selectin+ EVs, tissue factor (TF)-positive/CD20+ EVs, TF−/CD19+ EVs, TF−/CD45+ EVs, and TF−/CD20+ EVs were significantly higher in DLBCL patients compared to healthy controls. In contrast, the concentration of TF− PEVs was significantly lower in DLBCL patients compared to healthy controls. No statistically significant differences were observed in the concentrations of the EV profiles among the DLBCL patients with and without VTE. Using Cox regression analysis, we found that none of the observed EV populations demonstrated an association with overall survival (OS). In conclusion, patients with DLBCL have elevated concentrations of distinct EV populations—in particular, PEVs, E-selectin EVs, P-selectin EVs, TF+/CD20+ EVs, and TF− DLBCL/B-cell EVs (CD19, CD20, CD45)—compared to healthy controls. DLBCL patients exhibit a specific EV profile, which is not significantly related to the risk of VTE and OS outcomes. Our data provide an intriguing insight into EV profiles in patients with DLBCL. Additional research is needed to elucidate these findings further.

The treatment of chronic lymphocytic leukemia (CLL) consists of the continuous use of Bruton tyrosine kinase inhibitors (BTKis) such as ibrutinib, acalabrutinib, zanubrutinib and pirtobrutinib, or Bcl-2 inhibitors, such as venetoclax. Overall survival (OS) and progression-free survival (PFS) of CLL patients are significantly improved with the use of these therapies. Adverse effects (AEs) that can occur during treatment and the presence of pre-existing comorbidities in patients can influence subsequent treatment outcomes and, consequently, OS and PFS. Managing these AEs, including cardiologic toxicity and infections (including fungal infections), as well as treating cardiovascular and other comorbidities, can be challenging due to potential drug interactions with the medications used for the management of AEs and comorbidities. Therefore, this review examined the key challenges associated with the concomitant use of novel CLL therapies and medications for managing comorbidities and AEs. This review aims to enhance and facilitate the management of patients with CLL.
