Phase II trial of gemcitabine and weekly cisplatin for advanced non-small cell lung cancer.

Single-agent gemcitabine, when given in doses of > or = 1,250 mg/m2 weekly x 3 with a 1-week break, induces responses in approximately 20% of untreated patients with non-small cell lung cancer. This phase II study was undertaken to determine the efficacy of weekly administration of gemcitabine 1,500 mg/m2 combined with cisplatin 30 mg/m2 x 3 with a rest period of 1 week. Patients younger than 75 years were eligible if they had stage III/IV non-small cell lung cancer, a life expectancy > or = 12 weeks, hemoglobin > or = 10 g/dL, absolute granulocyte count > or = 10(9)/L, platelets > or = 100 x 10(9)/L, hepatic enzymes no more than three times the upper limit of normal, and serum creatinine < or = 130 micromol/L. There were 22 men and 18 women, with a median age of 60 years; 35 had a performance status of 0 or 1. Pathology included adenocarcinoma in 22 patients, squamous cell carcinoma in nine, large cell carcinoma in seven, and mixed non-small cell lung cancer in two. Six patients had stage III and 34 had stage IV tumors. Of the 39 patients eligible for response evaluation, partial remission was seen in 10, for an overall response rate of 26% (95% confidence interval, 12% to 41%). The median duration of response was 19 weeks (range, 7 to 32+ weeks). Grade 3/4 anemia was seen in 11 patients, and 21 patients required red blood cell transfusions. Grade 3/4 neutropenia occurred in 22 patients and grade 3/4 thrombocytopenia in 21 patients. One patient experienced febrile neutropenia Hematologic toxicity, particularly thrombocytopenia, was cumulative over time. Nonhematologic toxicity was modest, but one patient stopped therapy because of a grade 2 skin rash and one stopped because of a grade 4 pulmonary toxicity, both of which were thought to be related to gemcitabine. The modest activity of weekly gemcitabine and weekly cisplatin seen in this trial does not suggest in vivo synergy for these two agents as administered using this schedule and these doses.[1]
