Phase II study of docetaxel and celecoxib, a cyclooxygenase-2 inhibitor, in elderly or poor performance status (PS2) patients with advanced non-small cell lung cancer.

Introduction: The utility of two-drug chemotherapy regimens in elderly or performance status (PS 2) patients with advanced non-small cell lung cancer (NSCLC) remains to be established. Preclinical studies suggested that celecoxib, a Cyclooxygenase-2 inhibitor, has antitumor activity in NSCLC and can enhance the activity of chemotherapy drugs. We conducted a phase II study to evaluate the efficacy of the combination of weekly docetaxel and celecoxib in advanced NSCLC patients, who were either elderly (> or =70 years) or PS2.
