Mantle cell lymphomas: characteristics, natural history and prognostic factors of 45 cases.
We reviewed 77 cases considered as lymphocytic lymphomas of intermediate differentiation or diffuse centrocytic lymphomas. Forty-five cases were diagnosed as mantle cell lymphoma (MCL). The architectural pattern was diffuse in 95%, 8 cases presented large blastoid cells and CD5 positivity was observed in 28/34 cases. Of 20 cases studied, 8 presented a t(11;14)(q13;q32). Patient characteristics were: median age 59 years, B symptoms in 38%, 87% stages III-IV, bone marrow involvement in 67% with peripheral leukemic cells in 24%. Forty-four patients were treated with chemotherapy and 7 received radiotherapy. The complete response (CR) rate was 58%. Of the 26 CR, 19 relapsed at a median of 15 months. Disease-free survival was 42% and overall survival was 73% at 3 years. In a univariate analysis, overall survival was related to liver and bone marrow involvement, the presence of peripheral lymphomatous cells and achieving a complete response.
