RESUMO
Rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) is the most commonly used regimen for the upfront treatment of diffuse large B-cell lymphoma (DLBCL). However, it is associated with cardiotoxicity, especially in older patients. Substituting doxorubicin with non-PEGylated liposomal doxorubicin (R-COMP) may reduce the risk of cardiac events, but its efficacy has never been demonstrated in prospective trials. We describe the characteristics and outcome of patients with DLBCL aged ≥65 years prospectively enrolled in the Elderly Project by the Fondazione Italiana Linfomi and treated with full doses of R-CHOP or R-COMP per local practice. Starting from 1163 patients, 383 (55%) were treated with R-CHOP and 308 (45%) with R-COMP. Patients treated with R-COMP were older (median age, 76 vs 71 years), less frequently fit at simplified geriatric assessment (61% vs 88%; P < .001), and had a more frequent baseline cardiac disorders (grade >1, 32% vs 8%; P < .001). Three-year progression-free survival (PFS) was similar between R-CHOP and R-COMP (70% and 64%); 3-year overall survival was 77%, and 71% respectively. R-CHOP was associated with better PFS vs R-COMP only in the Elderly Prognostic Index (EPI) low-risk group. The two groups had similar rates of treatment interruptions due to toxicities or of cardiac events (P = 1.00). We suggest R-COMP is a potentially curative treatment for older patients with intermediate- or high-risk EPI, even in the presence of a baseline cardiopathy. R-CHOP is confirmed as the standard therapy for low risk patients.

Programmed death 1 (PD-1) blocking antibodies now represent a major advance in the treatment of patients with classical Hodgkin lymphoma (cHL) who relapse after autologous stem cell transplantation (ASCT) and pre- and/or post-ASCT brentuximab vedotin or after at least three lines of therapy. However, uncertainties still remain on the optimal use of these agents in refractory Hodgkin disease. A panel of experts was convened to produce a consensus document aimed at providing practice recommendations for the optimal use of PD-1 blocking antibodies in cHL, especially on pretreatment selection and evaluation of cHL patients' response and treatment length, management of PD-1 blockade therapy-treated patients, evaluation and management of toxicity. Our hope is that these recommendations might help hematologists to improve optimal management of patients with pretreated cHL.
