Rituximab should be the treatment of choice, at least in older patients with SMZL who have comorbid diseases. Am J Clin Pathol. Nonimmunoglobulin gene hypermutation in germinal esplenivo B cells.

A longer follow-up and the study of a larger group of patients are warranted to confirm our findings. Two out three patients, who received pentostatin as first line therapy, ttained a complete response CR. Cutaneous margina of follicular lymphomas.

Because of the indolent course of the disease, monotherapy with rituximab has previously been proposed. Ssplenico the complete responders seven patients had also a molecular remission.

Es una enfermedad relativamente agresiva con pobre respuesta a la quimioterapia convencional. After the fourth cycle of rituximab, she had achieved complete remission.


A clinicopathological study of 13 cases. The classification must be reproducible and clinically relevant, and sufficiently flexible to permit the incorporation of new data. This case demonstrates that rituximab monotherapy might also be a valid therapeutic approach in marginal zone lymphoma and autoimmune hemolytic anemia after failure of first-line treatment.

Using these 3 variables, we grouped patients into 3 prognostic categories: No existen datos que justifiquen reconocer esta variante como una enfermedad diferente. A clinical comparison of nodal and mucosa-associated lymphoid tissue types. Here, we reported on two cases of patients who underwent splenectomy and then presented disease progression after the procedure, but who showed an impressive response to rituximab monotherapy as a rescue treatment.

All patients were assessable: One out of the three partial responders have a persistent response. N Engl J Med.
