New options in the treatment of non-small cell lung cancer

The options for treating non-small cell lung cancer (NSCLC) were expanded by the introduction of the taxanes. As a single agent, docetaxel produced response rates ranging from 15 to 22% in evaluable patients in the second-line setting, with median duration of responses ranging from 5.6 to 7.5 months. To confirm the results observed in the phase II studies, a phase III trial was conducted. Three-hundred and seventy-three patients with advanced NSCLC who had failed prior platinum-based chemotherapy were randomized to receive docetaxel 100 mg/m2, docetaxel 75 mg/m2 or a reference arm consisting of vinorelbine or ifosfamide. Efficacy, safety and quality of life (using the Lung Cancer Symptom Scale) were assessed. Data from this study are forthcoming and may confirm the benefits provided by the inclusion of docetaxel in the second-line treatment of NSCLC. Docetaxel is also an active single agent in the first-line setting, with response rates ranging from 24 to 38% in evaluable patients, with a median survival of 6–13 months. Based on the single-agent activity, it was logical to evaluate the efficacy of docetaxel in combination with other active agents. As such, docetaxel has been studied in with numerous other agents such as vinorelbine, gemcitabine, platinums, etc. Notably cisplatin and carboplatin has shown promising rates of response and response duration in phase II trials. These combinations have now entered randomized phase III study.
