Central nervous system (CNS) relapse has not been extensively studied in mantle cell lymphoma (MCL). We retrospectively analyzed the risk factors and pattern of CNS relapse in consecutive patients with MCL. We identified 142 cases of MCL treated from 1980 to 2011. Median age at diagnosis was 68 years; 82% of patients had advanced stage; extranodal disease was reported in 89% of cases and high serum lactate dehydrogenase (LDH) in 40%. Fourteen patients (10%) did not receive treatment at diagnosis. Chemotherapy was administered to 125 patients (88%), in 21 cases (15%) including drugs penetrating into the CNS or given intrathecally; 49 patients (35%) had rituximab. Ten patients had front-line autologous transplant. After a median follow-up of 7.9 years, CNS relapse occurred in 11 cases (7.8%) at a median of 13.8 months. Actuarial risk of CNS relapse was higher in patients with elevated LDH (p = 0.002), higher International Prognostic Index (IPI) score (p = 0.018) and blastoid histology (p < 0.0001). Blastoid histology retained significance at multivariate analysis. Median survival after CNS relapse was 6.3 months. No front-line treatment reduced the risk of CNS relapse. Our analysis confirms the poor outcome of MCL after CNS relapse and may allow the identification of patients needing prophylaxis of CNS relapse.
Little information is available on the very elderly patients with diffuse large B-cell lymphoma (DLBCL). We performed a retrospective analysis of 281 patients >80 years old with newly diagnosed DLBCL treated in 4 referral institutions in Switzerland and Northern Italy. Primary end points were overall survival, progression-free survival, and cause-specific survival. Systemic chemotherapy was given to 239 patients, and 119 of them received rituximab in their initial treatment. At a median follow-up of 5.5 years, 5-year progression-free survival was 26% (95% confidence interval [CI], 20-32%), 5-year overall survival was 31% (95% CI, 25-37%), and 5-year cause-specific survival was 48% (95% CI, 41-55%) for the entire cohort. Rituximab and/or anthracyclines as part of initial treatment were associated with improved outcome. Cause-specific survival in patients receiving both agents approximated 60% at 5 years. At multivariate analysis, rituximab use maintained a significant prognostic impact after controlling for age, performance status, stage, haemoglobin, and lactate dehydrogenase levels. The International Prognostic Index as well as the more recently proposed revised-International Prognostic Index and National Comprehensive Cancer Center Network-International Prognostic Index could discriminate patients with significantly different outcomes. Albeit very elderly and potentially frail, there may be a potential for cure in fit DLBCL patients ≥80 years old. Accurate selection of patients able to tolerate proper immunochemotherapy is crucial.
Doxorubicin is the most effective single agent in the treatment of non-Hodgkin's lymphoma (NHL). Its use is limited because of the cardiac toxicity primarily in elderly patients (pts) and in pts with history of cardiac disease. Liposomal doxorubicin has been proven to reduce cardiotoxicity. The aim of this retrospective study was the use of nonpeghylated liposomal doxorubicin (NPLD) in term of efficacy, response rate and incidence of cardiac events. We retrospectively collected the experience of 33 Hematological Italian Centers in using NPLD. Nine hundred and forty-six consecu-How to cite this article: Rigacci L, Annibali O, Kovalchuk S, et al.
