Cardiac abnormalities can occur in patients treated with doxorubicin for lymphoma in the absence of CHF, even in patients who received moderate anthracycline doses. Male sex, older age, higher dose of doxorubicin, radiotherapy, and being overweight were risk factors for the development of cardiomyopathy.

Summary:Rituximab, an anti-CD20 monoclonal antibody, is increasingly used in the treatment of B-cell non-Hodgkin's lymphoma. Late-onset neutropenia in relation to rituximab has been recently described. In this report, we present six cases occurring after stem cell transplantation and discuss the potential impact of this complication.

BackgroundExtranodal nasal-type NK/T-cell lymphoma is a rare and severe disease. Considering the rarity of this lymphoma in Europe, we conducted a multicentric retrospective study on nasal-type NK/T cell lymphoma to determine the optimal induction strategy and identify prognostic factors.MethodsThirty-six adult patients with nasal-type NK/T-cell lymphoma were recruited and assessed. In total, 80 % of patients were classified as having upper aerodigestive tract NK/T-cell lymphoma (UNKTL) and 20 % extra-upper aerodigestive tract NK/T-cell lymphoma (EUNKTL).ResultsFor advanced-stage disease, chemotherapy alone (CT) was the primary treatment (84 % vs. 10 % for combined CT + radiation therapy (RT), respectively), while for early-stage disease, 50 % of patients received the combination of CT + RT and 50 % CT alone. Five-year overall survival (OS) and progression-free survival (PFS) rates were 39 % and 33 %. Complete remission (CR) rates were significantly higher when using CT + RT (90 %) versus CT alone (33 %) (p < 0.0001). For early-stage disease, CR rates were 37 % for CT alone versus 100 % for CT + RT. Quality of response was significantly associated with survival, with 5-year OS being 80 % for CR patients versus 0 % for progressive disease patients (p < 0.01).ConclusionEarly RT concomitantly or sequentially with CT led to improved patient outcomes, with quality of initial response being the most important prognosticator for 5-year OS.

Alemtuzumab, the monoclonal anti-CD52 antibody, has clinical activity in B-cell and T-cell malignancies at the dose of 30 mg three times weekly for 9-12 weeks. This standard regimen induced responses usually shorter than 6 months. To prolong time to progression, we initialized a phase II study with an identical initial scheme until partial response, followed by a maintenance therapy lasting at least 4 months. Eleven heavily pretreated patients (8 with B-chronic lymhocytic leukemia (B-CLL) and 3 with small lymphoctyic lymphoma (SLL)) have been treated with this maintenance regimen (MR patients) and were retrospectively compared to 5 patients (3 B-CLL and 2 SLL) treated with the standard regimen (SR patients). Patients characteristics before treatment were identical in both groups. Objective response was reached by 9 (82%) MR patients and 3 (60%) SR patients (p NS). After the treatment, 8 (73%) MR patients and all SR patients progressed with a median time at 12.2 months and 3 months respectively. Survival time from alemtuzumab was significatively different (P < 0.005). None of the patients died in the MR group with a median follow-up at 16 months. In the SR group, the median survival from alemtuzumab was 5.9 months. We did not observe any differences in terms of hematological toxicites and infections between the two groups. In conclusion, maintenance alemtuzumab therapy seems to increase the time to progression and the survival, without adding hematological toxicities and infectious complications. More patients are needed to confirm this observation.
