Weekly gemcitabine and monthly cisplatin for advanced non-small cell lung carcinoma.
Most chemotherapy for non-small cell lung cancer (NSCLC) currently includes combination chemotherapy based on cisplatin. Gemcitabine is a nucleoside analog with demonstrated activity against NSCLC, yet it has low toxicity. This phase II study was designed to examine the efficacy of a combination chemotherapy regimen consisting of gemcitabine followed by cisplatin. The patient population comprised 53 patients with pathologically confirmed locally advanced or metastatic NSCLC. Gemcitabine 1,000 mg/m2 was administered on days 1, 8, and 15 and cisplatin 100 mg/m2 was given on day 15. Chemotherapy was administered every 28 days. Of the 50 patients evaluable for response, there were two complete responses (4%) and 24 partial responses (48%). The median duration of response was 8.5 months, median survival was 13 months, and the 1-year survival rate was 61%. The regimen was generally well tolerated. World Health Organization grade 3 leukopenia occurred in 28.8% of patients, while grade 3 and 4 neutropenia occurred in 38.8% and 19.2% of patients, respectively. Grade 3 and 4 thrombocytopenia was seen in 13.3% and 7.7% of patients, and grade 3 and 4 anemia occurred in 11.5% and 1.9% of patients, respectively. Alopecia and oral toxicity was mild, although most patients experienced mild nausea and vomiting. Relatively few patients required dose modifications for any of the three weekly doses of chemotherapy. We conclude that the combination of gemcitabine and cisplatin is an effective regimen for NSCLC, resulting in high response and survival rates. Additional prospective randomized studies with other cisplatin-based combination chemotherapy regimens are warranted.
