Stage IV Breast Implant-associated Anaplastic Large-cell Lymphoma with Complete Pathologic Response to Neoadjuvant Chemotherapy.

Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is a rare lymphoma that has been associated with textured breast implants. Most cases present as a delayed (>1 year) seroma, which can be aspirated for diagnosis. Fewer patients present with masses or skin signs. Surgical resection is the cornerstone of treatment for this form of lymphoma. For advanced disease, treatment is multidisciplinary and incorporates adjuvant chemotherapy, radiation therapy, and potentially, the immunotherapeutic agent brentuximab vedotin, an anti-CD30 antibody-drug conjugate. However, relapse rates are high among patients with peripheral ALCL. We present the case of a 39-year-old woman who developed BIA-ALCL 13 years after augmentation with silicone, textured implants and had a complete pathologic response to neoadjuvant cyclophosphamide, doxorubicin (hydroxydaunomycin), vincristine (Oncovin), etoposide, prednisolone (CHOEP) at time of bilateral removal of implants and capsules. CHOEP is a long-standing regimen for treatment of peripheral ALCL and is a suggested regimen for treatment of BIA-ALCL. This case report is the first to demonstrate the use of neoadjuvant chemotherapy in the treatment of BIA-ALCL and suggests a role for its use in advanced disease.
