Abstract

BACKGROUND:

Primary lymphoma of the breast has been reported to have a high local and central nervous system recurrence (CNS) rate, suggesting the need for consolidation radiotherapy and CNS prophylaxis. A retrospective study was done to evaluate the institutional experience in this patient population.

METHODS:

In all, 37 patients with lymphoma involving the breast at initial diagnosis and managed at Stanford University from 1981-2005 were included. Diagnostic tissue biopsies were obtained either from the breast mass or an involved lymph node. Treatment and response data, patterns of recurrence, and outcomes were reviewed.

RESULTS:

Diffuse large B cell lymphoma (DLBCL) was the most common histologic subtype seen in 18 of 37 (49%) patients. Follicular and marginal zone subtypes were seen in 38%. Most patients presented with an incidental breast mass in stage I(E) or II(E). Four (11%) patients presented with bilateral breast involvement, with only 1 patient presenting with CNS disease. DLBCL patients received doxorubicin-based chemotherapy, with 70% receiving involved field radiotherapy and a single patient receiving intrathecal therapy. No recurrences occurred in the involved breast and a single parenchymal CNS recurrence was recorded. Among the DLBCL patients, the 5-year progression-free survival (PFS) was 61%, with a median follow-up of 3.8 years (range, 5 months to 19 years) and the 5-year overall survival (OS) was estimated at 82%. Patients with indolent lymphoma had an estimated 5-year PFS of 76% and an OS of 92%.

CONCLUSIONS:

DLBCL of the breast was successfully treated with doxorubicin-based chemotherapy alone or with involved field radiotherapy in an estimated 61% of patients at 5 years. A single CNS recurrence was observed in our series of patients, most of whom presented with limited disease.
