PURPOSE: To estimate the efficacy of third-generation (3G) chemotherapy agents (paclitaxel, docetaxel, gemcitabine, vinorelbine, and irinotecan) on response and survival in stage IIIB/IV non-small cell lung cancer (NSCLC). METHODS: A meta-analysis was performed using trials identified through MEDLINE. Results on tumor response and survival were collected from randomized trials comparing 3G monotherapy versus best supportive care (BSC), 3G monotherapy versus second-generation (2G) platinum-based regimens, and 3G platinum-based regimens versus 2G platinum-based regimens. RESULTS: Of the 2480 citations screened, 20 randomized controlled trials fulfilled the inclusion and exclusion criteria, and 19 trials were used in the analyses. The data from two, three-arm trials were used in two different comparisons. Five trials (n = 1029 patients) compared 3G monotherapy with BSC. The summary risk difference (RD) for 1-year survival favored 3G agents by 7% (95% confidence interval [CI]: 2%, 12%). Four trials (n = 871 patients) compared treatment with 3G monotherapy versus 2G platinum-based regimens. The response RD was -6% (95% CI: -11%, 0%), and the 1-year survival rate RD was 3% (95% CI: -3%, 10%), suggesting that despite a slightly higher response rate for 2G platinum-based regimens relative to 3G monotherapy, there is equivalency in survival. Twelve trials (n = 3995) compared 3G versus 2G platinum-based regimens. The RD for response was 12% (95% CI: 10%, 15%). A RD for 1-year was not calculated, because of heterogeneity among the trials. A subset analysis of 3G versus 2G platinum-based doublets revealed a 1-year survival-rate RD of 6% (95% CI: 2%, 10%), favoring 3G platinum-based regimens without evidence of heterogeneity. CONCLUSIONS: 3G agents have been a significant advance in the treatment of NSCLC.
