    Abstract:
    From March 1993 to May 1994, 32 chemotherapy-naive patients with advanced non-small cell lung cancer entered a phase I/II study to determine the maximum tolerated dose and the activity of the paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ)/cisplatin combination. The 21 men and 11 women had a median age of 59 years (range, 25 to 72 years) and a median performance status of 1 (range, 0 to 2). Histologic types were adenocarcinoma (13 cases), squamous cell carcinoma (10), and large cell carcinoma (nine). Nine patients had stage IIIB disease and 23 had stage IV disease. The first four dose levels of paclitaxel were 135, 175, 200, and 225 mg/m2 given with a fixed cisplatin dose of 100 mg/m2; at level 5, paclitaxel 225 mg/m2 was again given, and the cisplatin dose was increased to 120 mg/m2. Cycles were given every 3 weeks. Paclitaxel was administered as a 3-hour infusion followed by cisplatin, with standard premedication and hyperhydration. The maximum tolerated dose for the first cycle was not reached. Grades 3 and 4 neutropenia occurred in 24% and 16% of cycles (two cases with fever), respectively. Grades 2 and 3 peripheral axonal neurotoxicity occurred in two and 16 patients, respectively; the neurotoxicity appeared to be dose dependent and cumulative after a median total paclitaxel dose of 1,300 mg/m2. Of the 29 patients evaluable for efficacy, 11 (38%) had a partial response; efficacy was superior at paclitaxel doses of at least 200 mg/m2, with eight (47%) of 17 evaluable patients responding at these levels. In conclusion, at these doses of paclitaxel and cisplatin, the dose-limiting neurologic toxicity is dose dependent and cumulative after a total paclitaxel dose of approximately 1,300 mg/m2. This combination is highly active, with a total objective response rate of 38% and an objective response rate of 47% at paclitaxel doses of 200 mg/m2 or higher. Further evaluation is warranted.
