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.

ReviewEmerging role of docetaxel (Taxotere) in the adjuvant therapy of breast cancer.
The need for improved adjuvant chemotherapy programs for breast cancer patients is emphasized by the 1998 overview analysis of adjuvant trials, which demonstrates that although there has been substantial incremental advances in adjuvant therapy, relapse and death are prevented in less than half of women with micrometastatic disease. Because both docetaxel (Taxotere; Rhône-Pouleuc Rorer, Collegeville, PA) and paclitaxel have substantial non-cross-resistance with anthracyclines and therefore activity in anthracycline-resistant breast cancer, defining their roles in the adjuvant therapy of breast cancer is an area of great interest and active clinical investigation. ⋯ Ongoing or soon-to-open adjuvant trials are evaluating the impact of docetaxel added to conventional adjuvant anthracyclines regimens, substituted for anthracyclines, used in combination with anthracyclines, and in direct comparison to paclitaxel. The results of these ongoing adjuvant trials will define the role of docetaxel in adjuvant chemotherapy programs for the management of patients with breast cancer and are eagerly awaited.

ReviewDoxorubicin/taxane combinations: cardiac toxicity and pharmacokinetics.
Doxorubicin and the taxanes, paclitaxel and docetaxel (Taxotere; Rhône-Poulenc Rorer, Collegeville, PA), are among the most active cytotoxic agents for the treatment of metastatic breast cancer. Given their activity, relative non-cross-resistance, partially non-overlapping toxicities, and differing mechanisms of action, there is a clear rationale for combining these agents for both advanced and early stage disease. Phase I and II trials have been reported for both doxorubicin/paclitaxel and doxorubicin/docetaxel. ⋯ This is likely explained by a pharmacokinetic interference of doxorubicin elimination by paclitaxel, an effect that is highly dependent on the interval between administration of the drugs and the duration of the paclitaxel drug infusion. Such an interaction has not been observed with doxorubicin/docetaxel, providing an explanation for the lack of enhanced cardiotoxicity with docetaxel-containing combination. Phase III trials comparing doxorubicin/taxane combinations with standard regimens have been completed and are in progress, and should help define whether the use of these drugs in combination offers any advantage over their use in a sequential fashion in both early and advanced disease.
