RESUMO
<p><b>OBJECTIVE</b>To analyze clinical features, therapeutic effects and prognostic factors of patients with mantle cell lymphoma (MCL).</p><p><b>METHODS</b>Clinical data of 37 MCL patients hospitalized in our hospital from January 2000 to March 2010 were retrospectively analyzed.</p><p><b>RESULTS</b>The median age was 62, with a male predominance. 97.30% of the patients were in Ann Arbor stage III ∼ IV, 54.05% with B symptoms, 64.86% with bone marrow involvement, 29.73% with splenomegaly, 24.32% with lymphocytosis and 51.35% with elevated LDH. Ki-67 was detected in 22 cases, and patients with Ki-67 ≤ 40% accounted for 68.18%. Of 37 cases, the overall response rate (ORR) of rituximab combined with chemotherapy was 92.31%, being higher than those of CHOP (46.15%) and CHOP + IFN (42.86%) regimens. There were statistical differences in the 3-year progression-free survival (PFS) and overall survival (OS) between rituximab + chemotherapy and CHOP or CHOP + interferon regimens (P < 0.05, respectively). Splenomegaly, elevated WBC, lymphocytosis and Ki-67 > 40% were identified as adverse prognostic factors.</p><p><b>CONCLUSION</b>Most patients with MCL were older adults, with a male predominance and usually had bone marrow involvement and poor prognosis. Rituximab combined with chemotherapy could improve ORR and OS of MCL.</p>
