A retrospective study was done to evaluate the institutional experience in this patient population.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS.<\/jats:title><jats:p>In all, 37 patients with lymphoma involving the breast at initial diagnosis and managed at Stanford University from 1981\u20132005 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.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS.<\/jats:title><jats:p>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<jats:sub>E<\/jats:sub> or II<jats:sub>E<\/jats:sub>. Four (11%) patients presented with bilateral breast involvement, with only 1 patient presenting with CNS disease. DLBCL patients received doxorubicin\u2010based 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\u2010year progression\u2010free survival (PFS) was 61%, with a median follow\u2010up of 3.8 years (range, 5 months to 19 years) and the 5\u2010year overall survival (OS) was estimated at 82%. Patients with indolent lymphoma had an estimated 5\u2010year PFS of 76% and an OS of 92%.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS.<\/jats:title><jats:p>DLBCL of the breast was successfully treated with doxorubicin\u2010based 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.
