Celecoxib: a novel treatment for lung cancer.
Lung cancer is by far the leading cause of cancer-related deaths. Overall survival is poor and has not improved substantially over the last 50 years. Therefore, it is clear that novel and more effective treatments are needed to improve the outcome of therapy. Recent attention has been drawn to the role of cyclooxygenase (COX)-2 in the pathogenesis of cancer, and it has been considered as an attractive target for therapeutic and chemopreventive strategies in lung cancer patients. Celecoxib (Celebrex), Pfizer), a selective COX-2 inhibitor and potent anti-inflammatory agent, has been approved for the treatment of osteoarthritis and rheumatoid arthritis. This orally administered agent is generally well tolerated and has almost no gastrointestinal or renal toxicity. Phase II clinical trials suggest that COX-2 inhibition by celecoxib would enhance response to cytotoxic chemotherapy or radiation therapy through interference with cellular proliferation and tumor angiogenic processes, promotion of apoptosis and immune surveillance, or other possible mechanisms. Celecoxib has shown promising antitumor efficacy in lung cancer and a large variety of solid tumors that rely on COX-2-related mechanisms for growth and survival. This article reviews the profile of celecoxib and evidence supporting its role in the therapy of lung cancer.
