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) and neoadjuvant chemotherapy for non-small cell lung cancer.
In locally advanced non-small cell lung cancer with ipsilateral (N2) or contralateral (N3) mediastinal node involvement, the presence of micrometastases results in a poor outcome when patients are treated by surgery alone. The prognosis is also bad in inoperable locally advanced disease (T4) treated solely by radiotherapy. Compared with surgery or radiotherapy alone, the additional use of cisplatin-based induction chemotherapy has been shown to significantly increase the prospects of long-term survival in these patients. ⋯ Several ongoing phase I/II studies are investigating neoadjuvant regimens in which docetaxel is combined with agents such as cisplatin and carboplatin. In preliminary results from a study of docetaxel plus cisplatin, an objective response was seen in 70% of 20 evaluable patients. It is hoped that the use of docetaxel in single-agent or combination induction regimens will prove to prolong patient survival.

ReviewThe role of docetaxel (Taxotere) in neoadjuvant chemotherapy of breast cancer.
Neoadjuvant chemotherapy has become standard therapy in the management of breast cancer patients with locally advanced disease with inoperable tumors and inflammatory breast cancer. Patients with earlier stage breast cancer and operable tumors may also benefit from treatment with neoadjuvant chemotherapy. Docetaxel (Taxotere; Rhône-Poulenc Rorer, Collegeville, PA) is thought to be one of the most potent agents in the treatment of metastatic breast cancer and is therefore being investigated for its likely benefit in preoperative, neoadjuvant regimens. ⋯ Preliminary findings demonstrate high complete and partial response rates and a tolerable toxicity profile. These results are consistent with the view that incorporation of docetaxel in neoadjuvant chemotherapy regimens will contribute to improved patient outcome. Ongoing studies will provide important information regarding the most appropriate regimens and schedules of docetaxel to use in the preoperative, neoadjuvant setting.

ReviewWeekly administration of docetaxel (Taxotere): summary of clinical data.
Docetaxel (Taxotere; Rhône-Poulence Rorer, Antony, France) is a highly efficacious antineoplastic agent; however, its administration every 3 weeks produces substantial myelosuppression. Based on recent observations that the administration of paclitaxel on a weekly schedule minimizes myelosuppression, investigation of weekly docetaxel has been initiated. A recently completed phase I study of weekly docetaxel demonstrates markedly decreased myelosuppression with this schedule. ⋯ When used concurrently with radiation therapy, weekly scheduling allowed a maximization of docetaxel dosing, with the maximum tolerated dose being 20 mg/m2/wk. It is likely that this novel schedule of docetaxel will allow the drug to be used with decreased toxicity and will facilitate its incorporation into active combination regimens. Further investigation of this novel schedule of administration is warranted.

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.
