Abstract
Primary breast lymphoma (PBL) is a rare disease accounting for 0.4–0.5 % of all breast malignancies. Accumulating evidence indicates that the diagnosis, prognostic factors, and optimal management of PBL are difficult. The present study aims to investigate the clinicopathological features and optimal treatment of PBL and to evaluate the institutional experience in this patient population. A total of 30 patients with PBL from January 2002 to December 2012 treated in He’nan Province Tumor Hospital were selected. The patients’ clinical and pathological characteristics, treatment and response data, patterns of recurrence, and outcomes were retrospectively analyzed, and the relevant literatures were reviewed. All the cases were female, and the median age was 45. Diffuse large B cell lymphoma was the most common histological subtype seen in 23 of 30 patients. With a median follow-up time 32 months, median OS was 42 months (95 % CI 25–58 months), with 5-year OS rates 48 % (95 % CI 36–59 %). The median PFS was 14 months (95 % CI 6–30 months), with 5-year PFS rates 32 % (95 % CI 20–45 %). The prognostic factors that retained statistical significance for OS were IPI (P < 0.001), age (P = 0.04), and stage (P < 0.001). For PFS, significant prognostic factors were IPI (P = 0.01), radiotherapy given (P = 0.02) and stage (P = 0.02). PBL appears to have a worse prognosis. The present treatment method for PBL is a comprehensive way of diagnostic surgery together with radiotherapy and chemotherapy.
