Lymphocytes are present in normal breast. A lymphocytic mastopathy characterized by a lymphocytic infiltrate within the breast epithelium has been described, but its relevance as a precursor lesion of mucosa-associated lymphoid tissue (MALT)-type lymphoma of the breast is uncertain. Lymphomas of the breast are uncommon, and a broad variety of histologic types have been reported. ⋯ Burkitt's or Burkitt-like lymphoma can bilaterally involve the breast of a young pregnant or lactating woman and typically behaves aggressively. Primary breast lymphomas behave similarly to lymphomas of similar histologic types and stages presenting at other sites. Treatment of primary breast lymphomas does not include surgery, but is typically based on local radiotherapy, often combined with systemic chemotherapy.

ReviewDocetaxel (Taxotere) in combination with platinum-based regimens in non-small cell lung cancer: results and future developments.
The combination of docetaxel (Taxotere; Rhône-Poulenc Rorer, Antony, France) with cisplatin is feasible, has manageable toxicity, and is active in stage IIIB/IV non-small cell lung cancer. The four phase II trials completed to date show response rates ranging from 32% to 48% and median survival durations of 8 to 13 months. ⋯ Overall, this combination is also well tolerated. However, it will be necessary to use both docetaxel/platinum regimens at earlier stages in the disease if a significant impact is to be made on survival.

Clinical TrialDocetaxel (Taxotere) in combination with vinorelbine in non-small cell lung cancer.
Following encouraging preclinical evidence suggesting anticancer synergy when docetaxel (Taxotere; Rhône-Poulenc Rorer, Antony, France) and vinorelbine are administered together, a clinical trial was designed to determine the maximum tolerated dose of the combination when given with granulocyte colony-stimulating factor support to 27 patients with advanced non-small cell lung cancer. Doses were escalated in stages to a maximum of 45 mg/m2 vinorelbine and 60 mg/m2 docetaxel, both administered on day 1 of a 2-week cycle. Hematologic toxicity was mild, with febrile neutropenia complicating only four of the 209 cycles delivered. ⋯ Major response was seen in 37% of patients. The median survival was 9 months and 1-year survival was approximately 35%. The combination of 45 mg/m2 vinorelbine and 60 mg/m2 docetaxel has now moved into a phase II trial.

ReviewPhase III randomized trials of docetaxel in patients with metastatic breast cancer.
In a randomized phase III trial in which docetaxel was compared with doxorubicin in metastatic breast cancer patients who had failed prior alkylating chemotherapy, docetaxel proved more active, achieving responses at a significantly higher rate (complete + partial responses, 48% v 33%). The risk to benefit ratio favors docetaxel. The higher response rate was achieved without the risk of potentially fatal cardiac toxicity evident in patients who received doxorubicin and with a lower risk of infection and febrile neutropenia. ⋯ Those assigned to docetaxel lived significantly longer (median survival, 11.4 v 8.7 months), experienced a longer time before disease progression (19 weeks v 11 weeks), and achieved a higher overall response rate (30% v 11.6%). The toxicity profile of both regimens was manageable. These phase III studies confirmed the activity observed with docetaxel in the phase II trials and support the view point that docetaxel is one of the most active agents available for the treatment of breast cancer.

ReviewPhase I-II studies of docetaxel as a single agent in the treatment of metastatic breast cancer.
Docetaxel (Taxotere, Rhône-Poulenc Rorer, Antony, France) is highly effective in the first-line treatment of metastatic breast cancer, achieving an objective response rate of 61% (95% confidence interval, 52% to 69%). This rate of response is seen in patients with poor prognostic factors such as liver metastases and multiple organ involvement. ⋯ Phase II data suggest that docetaxel is the most active agent yet available in the treatment of advanced breast cancer; this conclusion is now supported by the results of randomized phase III trials. These data justify the further investigation of docetaxel alone and in combination chemotherapy.
