Taxanes, past, present, and future impact on non-small cell lung cancer.

Taxanes are novel microtubule-stabilizing agents and have shown efficacy in non-small cell lung cancer (NSCLC) since the 1990s. Paclitaxel and docetaxel have been used either as single agents or in combination with a platinum compound. The newer generation albumin-bound taxane, nab-paclitaxel, has also shown similar efficacy in advanced NSCLC, both as a single agent and in combination with a platinum compound. Nab-paclitaxel, being Cremophor EL free, appears to have a better toxicity profile than paclitaxel. Taxane/platinum combinations still remain the foundation of treatment for advanced or metastatic NSCLC. Docetaxel and paclitaxel as single agents have also shown efficacy in the second-line setting in advanced/metastatic NSCLC. Oral formulations of paclitaxel and docetaxel are of great interest, but have yet to receive regulatory approval in this disease. The phase I-II trials have shown that these formulations are feasible in the clinical setting.
