Non-Hodgkin lymphoma of the breast is an uncommon form of lymphoma occurring either primary disease (PBL) or part of systemic involvement. We report the clinical outcome of 4 consecutive cases with CD20+ diffuse large B-cell lymphoma (DLBCL) of the breast, in the attempt to further clarify the management of this disease. The median age was 53 years (39-61), stages were IIE (n=2), IIIE (n=1), and IV (n=1); IPI scores were 0 (n=2), 2 (n=2). Two cases were PBL, and 2 were secondary involvement of the breast. Two stage HE patients received MACOP-B, radiation therapy was given to one of them and both achieved CR. The stage HIE patient treated with MACOP-B plus Rituximab was in PR at the beginning of the Rituximab and achieved CR at the end of the treatment. The 61-year-old stage IV patient and bilateral involvement received P-VNBEC as first line treatment, achieving PR; she was then treated with 4 cycles of MACOP-B plus Rituximab obtaining CR. After a median follow-up of 40 months (31-50) all patients are alive and in CR. No CNS prophylaxis was given and no incidence of CNS relapse was observed. In our experience DLBCL of the breast shows chemosensitivity to MA-COP-B regimen but the intensification with Rituximab seems to be effective especially in the advanced stages. Further and comparative studies are required to confirm the validity of our results.
