Combination of gemcitabine and cisplatin as first-line therapy in advanced non-small-cell lung cancer.

PURPOSE

The prognosis of patients with advanced non-small-cell lung cancer (NSCLC) is extremely poor. Many prospective randomized trials on patients with advanced NSCLC suggested systemic chemotherapy improves both the survival and quality of life. A phase II trial was conducted to evaluate the efficacy and safety profile of the combination chemotherapy of gemcitabine and cisplatin in advanced NSCLC.

MATERIALS AND METHODS

Forty-four patients with locally advanced or metastatic NSCLC were enrolled. The patients received a cisplatin, 75 mg/m(2), infusion over 30 minutes on days 1, followed by a gemcitabine, 1,250 mg/m(2), infusion over 30 minutes on days 1 and 8 every 3 weeks.

RESULTS

The median age of the patients was 64 years (range: 27 approximately 75). Forty-one patients were assessable for response and toxicity analyses. The overall response rate was 53.6%, but with no complete remissions. The median time to progression was 5.6 months (range: 1 approximately 15.4). The median survival was 14.2 months (95% confidence interval (CI), 13.8 approximately 22.5). A total of 179 cycles were administered, with a median of 4 cycles of chemotherapy, ranging from 2 to 9 cycles. The most common hematological toxicities were NCI grades 3/4 neutropenia (24%) and thrombocytopenia (7.8%). The most common non-hematological toxicity was fatigue (42.4%). There were no life-threatening toxicity or treatment related mortalities. The median duration of follow up was 9.4 months, ranging from 1.6 to 30.3 months.

CONCLUSION

In this trial, the combination of gemcitabine and cisplatin showed significant activity, with acceptable and manageable toxicities as a first-line regimen for patients with advanced NSCLC.
