title: Gemcitabine for the treatment of non-small-cell lung cancer.
abstract: Platinum-based chemotherapy regimens have been the mainstay of treatment for non-small-cell lung cancer because they improve survival. Although there is no standard platinum-based regimen, combination regimens with newer agents (e.g., gemcitabine [Gemzar], paclitaxel [Taxol], and vinorelbine [Navelbine]) are superior to platinum alone or in combination with older agents (e.g., etoposide). Four phase III clinical studies demonstrate the favorable activity and toxicity profile of gemcitabine in combination with cisplatin (Platinol) for the treatment of patients with stage IIIB or IV non-small-cell lung cancer. These studies show overall response rates of approximately 30% to 60% with gemcitabine regimens versus overall response rates of 11% with cisplatin alone, 22% with cisplatin plus etoposide, 25% with cisplatin plus vinorelbine, and 40% with cisplatin plus mitomycin and ifosfamide (Ifex). Median survival time with gemcitabine regimens ranged from 8.1 to 9.8 months. Thrombocytopenia and anemia are the principal toxicities with gemcitabine regimens. Because of the favorable results with gemcitabine regimens, this drug is being evaluated in combination with carboplatin (Paraplatin) in newly diagnosed patients with stage IIIB or IV disease and good performance status, or as single-agent therapy in patients with poor performance status.
