Docetaxel is a semisynthetic taxane, a class of anticancer agents that bind to beta tubulin, thereby stabilising microtubules and inducing cell-cycle arrest and apoptosis. Docetaxel was first approved for the treatment of anthracycline-refractory metastatic breast cancer in the mid-1990s. Since then, several randomised trials have reported improved time-to-progression, overall survival, or both in metastatic breast cancer treated with single-agent docetaxel or docetaxel-based combination regimens. Data from two adjuvant trials have shown a survival benefit with the addition of docetaxel to standard anthracycline-based regimens in patients with high-risk early breast cancer. In four randomised studies, docetaxel improved survival in locally advanced or metastatic non-small-cell lung cancer. Moreover, two trials have shown that docetaxel combined with estramustine or corticosteroids improves survival in metastatic androgen-independent prostate cancer. Here, we review major randomised phase III trials with docetaxel in the treatment of solid malignant disease.

The epothilones are a new class of non-taxane tubulin polymerization agents obtained by natural fermentation of the myxobacteria Sorangium cellulosum. The cytotoxic activities of the epothilones, like those of the taxanes, have been linked to stabilization of microtubules, but they also have important differences. Among the epothilone family, ixabepilone (BMS247550) is a semisynthetic derivative of the natural product epothilone B. Ixabepilone was evaluated in vivo in a panel of human and rodent tumour models, the majority of which were chosen because of their known, well-characterized resistance to paclitaxel, and seems able to overcome the over-expression of multidrug resistance and to be unaffected by mutations in the beta tubulin gene. The interest of ixabepilone was clinically confirmed in clinical studies of phase II which demonstrated a strong activity at the patients with metastatic breast cancer resistant to taxanes and in patients suffering of other types of chemoresistant tumors.
