A phase II study of carboplatin plus gemcitabine in advanced non-small-cell lung cancer (NSCLC): a hoosier oncology group study.
The purpose of this study was to evaluate the toxicity and determine the response rate, duration of remission, and survival using gemcitabine plus carboplatin in non-small cell lung cancer (NSCLC). This was a phase II study of gemcitabine and carboplatin in chemotherapy-naive patients with advanced NSCLC and Karnofsky Performance Status of at least 80. Gemcitabine was administered intravenously at 1,000 mg/m2 weekly for 3 weeks followed by 1 week rest. Carboplatin was administered immediately after gemcitabine at an area under the curve (AUC) of 5 given intravenously on day 1 of an every-4-week cycle. Seven patients were entered in the study and five were evaluable for toxicity. The median age of patients was 68 years (range, 52-72). The protocol was prematurely terminated because of severe and unexpected hematologic toxicity. Grade 3-4 thrombocytopenia was observed in four of the first five patients. These toxicities were all observed with the first course of chemotherapy. There were no objective responses seen. Median survival time was 130 days. Carboplatin plus gemcitabine was a logical combination. However, because of the severe thrombocytopenia associated with this regimen, we do not recommend this two-drug combination in the dose and schedule used in this study.
