Meta AnalysisDocetaxel (Taxotere): an effective agent in the management of second-line breast cancer.
Despite improvements in detection and management, metastatic breast cancer remains a leading cause of death among women in industrialized countries. Chemotherapy is the initial treatment of choice for patients with a negative estrogen receptor status, as well as for those with a positive estrogen receptor status who have failed to respond to endocrine treatment. Patients who fail on first-line chemotherapy become candidates for second-line salvage chemotherapy; the outlook for these patients is poor, and new active agents continue to be sought. ⋯ Docetaxel also was found to be highly effective in patients with a poor prognosis, having metastases in three or more organs (53%), and/or visceral sites of disease (47%). Furthermore, the overall response rate for docetaxel in the intent-to-treat population (42.5%) is superior to the response rate of either doxorubicin as second-line therapy (29.3%) or paclitaxel (Taxol; Bristol-Myers Squibb Oncology, Princeton, NJ) when used as first- or second-line therapy (29%) in metastatic disease. In conclusion, docetaxel appears to be a very effective therapeutic option for women with second-line metastatic breast cancer.

Meta Analysis Clinical TrialDocetaxel (Taxotere) in combination: a step forward.
Docetaxel (Taxotere; Rhône-Poulenc Rorer, Antony, France) is a hemisynthetic derivative from European yew that inhibits tubulin depolymerization and enhances the formation of microtubule bundle aggregates, causing cell death. Activity against a variety of tumor types has been reported. Single-agent chemotherapy is rarely curative; hence, combination regimens are the logical next step in the attempt to improve tumor reduction and prolong survival. ⋯ The docetaxel/vinorelbine combination produced responses at all dose levels as front-line therapy for metastatic breast cancer; dose-limiting toxicity was experienced by two patients, but only when the vinorelbine dose was raised to 22.5 mg/m2. In phase II studies in non-small cell lung cancer, preliminary results have shown the docetaxel/cisplatin combination to have a promising level of activity and an acceptable toxicity profile. Future trials will continue to evaluate the role of docetaxel in combination and in sequential regimens, most particularly in metastatic breast cancer and non-small cell lung cancer.
