Lymphoma of the breast in Hong Kong Chinese.

Abstract

Fourteen cases of non-Hodgkin's lymphoma presenting as breast mass from 1974 to 1996 were reviewed. The median age of presentation was 51 years. Three patients had bilateral disease and five had disseminated disease. A predominance of B cell disease of diffuse large cell histology was noted. Painless lumps were the most common presenting features and most patients were treated with excisional biopsy followed by combination chemotherapy. Radiotherapy was added to local bulky disease. Six patients, however, underwent mastectomy. The overall CR rate was 74 per cent, lasting a median of 32 months. At a median follow-up of 60 months five patients were still alive, one with relapsed disease. Salvage treatments for relapsed patients were uniformly poor. Compared to reported western series, our patients had more high grade disease, more T cell disease and more CNS relapses. Improvements in treatment may involve the use of fine needle aspiration of breast lesion prior to surgery, primary CNS prophylaxis in high grade disseminated disease and high dose chemotherapy with marrow/stem cell rescue in relapsed cases.
