    Abstract:
    Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) and cisplatin are cytotoxic drugs active against non-small cell lung cancer (NSCLC) that possess additive cytotoxicity in animal tumors. Paclitaxel and cisplatin are active in patients with advanced NSCLC when given on a 3-weekly schedule. In an attempt to increase activity, we designed a phase II study with a biweekly schedule. Paclitaxel 110 mg/m2 was given by 3-hour intravenous infusion, followed by cisplatin 60 mg/m2 via intravenous infusion. Treatment was scheduled every 2 weeks. Of the 42 patients treated, 19 were men and 23 were women, with a median age of 54 years (range, 31 to 69 years). Four patients had stage IIIA NSCLC, 18 stage IIIB, and 20 stage IV. Median World Health Organization performance status was 1 (range, 0 to 2), and adenocarcinoma was the most common histology (52%). A median of nine cycles was administered (range, one to 24 cycles), with more than 360 cycles administered. Rates of frequency of World Health Organization grade 3 or 4 toxicities were as follows: neutropenia, 20%; thrombocytopenia, 2%; nausea/vomiting, 7% (despite prophylactic treatment with 5-HT3 receptor antagonists plus prednisolone); neurotoxicity, 2%; and nephrotoxicity, 2%. There were three septicemic episodes, no bleeding episodes, and no toxic deaths. Dose reduction was performed in 15 patients (36%), due to nephrotoxicity in 14 cases. Treatment delay was necessary in 23 patients (55%), most often due to neutropenia (nine cases). Forty patients are currently evaluable for response, with two complete and 15 partial responses (overall response rate, 43%; 95% confidence limits, 27% to 59%). Median response duration was 31 weeks (range, 9 to 85 weeks). The biweekly schedule of paclitaxel plus cisplatin has noteworthy activity in patients with NSCLC. A relatively large fraction of patients required either dose reduction and/or treatment delay, but World Health Organization grade 3 or 4 toxicity was rare, apart from the neutropenia that caused only a few septicemic episodes.
