title: Primary breast lymphoma: 30 years of experience with diagnosis and treatment at a single medical center.
abstract: In our retrospective study covering the past 30 years at a tertiary cancer care institution, we review 30 patients with primary breast lymphoma (stage I or II) and analyze the different treatment modalities. All 30 patients had unilateral disease, and the median age was 67.5 years. Two patients refused treatment and, hence, were excluded from our study. Of the 28 remaining patients, 11 (39%) were treated with a single treatment modality, and 17 (61%) underwent different combinations of surgery, radiation therapy, and chemotherapy. Seventeen patients underwent a surgical resection as the primary modality or as part of a multimodality therapy. Seven patients (25%) experienced a local or distal recurrence of the disease. Of these 7 patients, 6 underwent surgery as the primary treatment or as part of a combined treatment modality, and 1 underwent radiation therapy only. Eighteen patients (64%) died during the follow-up period ranging from 6 to 230 months, but only 5 of these 18 patients (28% [18% of all patients]) died of disease-specific causes. Of the 2 patients who were only treated with chemotherapy, 1 had primary breast lymphoma that never went into remission. In our study, surgery as the primary modality therapy or as part of a multimodality therapy for primary breast lymphoma is associated with a higher rate of treatment failure, whereas a combination of chemotherapy and local radiation therapy provides the best results. However, because our sample size is small, for such a rare neoplasm, definitive treatment recommendations are difficult to determine.
