About A Case: Primary Breast Lymphoma (Diffuse Large B cell Lymphoma)

Primary breast lymphoma is a rare neoplasia, with little clinical and imaging specificity. These are essentially type B lymphomas, of which the most common is diffuse lymphoma with large B cells. It is an entity that presents a prognostic impact from the outset by their localization but also by the risk of neurological relapse. The treatment of primary breast lymphoma depends on lymphomatous localizations and of course the histological type. There remain some questions to be raised regarding the place of radiotherapy in the treatment of certain localized histological forms, as well as the interest of systematic neuromeningeal prophylaxis in this breast localization. We report a case of primary breast lymphoma in a 50-year-old patient with no particular history.

Advances in Diagnosis and Treatment of Primary Breast Lymphoma -Review

Primary breast lymphoma(PBL) is a rare and unique type of lymphoma. Female patients are the majority, but its pathogenesis is not clear, and the estrogen may be related with the pathoganesis. Women who have breast implants have more chance to be suffered. The painless breast masses are the most common clinical manifestations, which is similar to breast cancer. Surgical resection of the mass and core needle biopsy are helpful for the diagnosis. The most common pathological type of PBL is diffuse large B cell type, with non GCB type, and it is prone to extranodal relapse in which central nervous system relapse is common which has poor prognosis. Therapy combined with surgery, chemotherapy and radiotherapy are requied, but rituximab added failed to improve its survival. Small molecular targeted drugs may be beneficial to PBL. In this article, the pathogenesis, clinical characte ristics, diagnosis and treatment of PBL are briefly summarized.

Rituximab and dose dense chemotherapy in primary breast lymphoma

Treatment of primary breast lymphoma (PBL) remains unsatisfactory. We assess a clinical study to evaluate efficacy and toxicity of a dose dense regimen (CEOP-14) and rituximab in 32 previously untreated female patients with PBL in early stage. There was no difference in complete response rate (87%), event free-survival (75%) and overall survival (63%) compared with historical patients.

Primary breast lymphoma: A pooled analysis of prognostic factors and survival in 93 cases

BACKGROUNDPrimary breast lymphoma is a rare disease. The small number of patients and the paucity of data make large-series studies difficult. We conducted a pooled analysis to evaluate the treatment outcome and prognostic factors in patients with primary breast lymphoma.METHODSIn a search of PUBMED and MEDLINE we found 7 observational studies with 93 patients that were eligible for inclusion. Treatments included single therapy or combined surgery, chemotherapy and radiotherapy. We analyzed the correlation between treatment protocols, tumor relapse and survival. Histopathology and cancer stage were analyzed to evaluate their significance in treatment outcome.RESULTSAll 93 patients were female, with a mean age of 57 years. The histopathology of 63 patients (68%) was diffuse large cell lymphoma. According to Ann Arbor classification, 57% were stage I, 23% were stage II, 4% were stage III, and 16% were stage IV. Thirteen percent received surgery alone, 27% received chemotherapy alone, 7% received radiotherapy alone, 10% received surgery and chemotherapy, 10% received surgery and radiotherapy, 22% received chemotherapy and radiotherapy, and 11% received surgery combined with chemotherapy and radiotherapy. With a median follow-up duration of 34 months (mean, 53 months), 48% had relapse of disease, 50% had no relapse, while 2% had disease progression. The mean time to first tumor relapse after treatment was 20 months. The 3-year and 5-year overall survival rates were 70% and 56%, respectively. Radiotherapy was a significant prognostic factor predicting tumor relapse (P=0.044). Tumor stage was a significant prognostic factor affecting overall survival, disease-free survival and disease-specific survival (P=0.0231, 0.0015, 0.0124, respectively).CONCLUSIONWith a 3-year overall survival rate of 70%, the high relapse rate of 48% is a cause for concern. Patients who received chemotherapy and radiotherapy had better survival outcome and a lower relapse rate. We suggest that chemotherapy and radiotherapy be the initial treatment for patients with primary breast lymphoma.
