Primary breast diffuse large B-cell lymphoma in the rituximab era: Therapeutic strategies and patterns of failure.

ABSTRACT: Primary breast diffuse large B-cell lymphoma (PB-DLBCL) is a rare subtype of DLBCL with limited data on patterns of failure. This multicenter study aimed to define the optimum treatment strategy and patterns of failure for PB-DLBCL patients. We retrospectively reviewed data on 108 PB-DLBCL patients from 21 Chinese medical centers. Only patients with localized disease (involvement of breast and localized lymph nodes) were included. After a median follow-up of 3.2 years, 32% of patients developed progression or relapse. A continuous pattern of relapse was observed, characterized by frequent late relapses in the contralateral breast and central nervous system (CNS). Although rituximab significantly reduced the overall cumulative risk of progression or relapse (5-year cumulative risk 57% vs 24
