PURPOSE:

This study evaluates the activity and toxicity of the paclitaxel/carboplatin (PC) doublet versus vinorelbine/carboplatin (VC) doublet as second-line treatment in patients who have advanced non-small-cell lung cancer (NSCLC).

PATIENTS AND TREATMENT:

Patients pretreated with front-line docetaxel and gemcitabine were randomized to receive either PC (n = 75), which consisted of paclitaxel at a dose of 140 mg/m(2) and carboplatin area under the curve (AUC3), or VC (n = 78), which consisted of vinorelbine at a dose of 45 mg/m(2) orally and carboplatin AUC3; both drugs were administered on days 1 and 15.

RESULTS:

The overall response rate was 18.6% (95% confidence interval, 9.85%-27.49%; one complete and 13 partial responses) in the PC arm and 7.7% (95% confidence interval, 1.78%-13.61%; one complete and five partial responses) in the VC arm (P = .056). Median time to tumor progression was 3.5 months (range, 0.3 – 23.73 months) and 3.07 months (range, 0.37-18.5) in the PC and VC arm, respectively (P = .287). Median overall survival was 7.83 months (range, 0.3-45.03 months) and 7.60 months (range, 0.5-30.27 months) for PC and VC arms, respectively (P value = .633). Chemotherapy was well-tolerated and grade III/IV toxicities were relatively infrequent. No toxic deaths were observed.

CONCLUSIONS:

Platinum-based doublets with either paclitaxel or vinorelbine in patients with advanced/metastatic NSCLC pretreated with front-line docetaxel/gemcitabine show comparable efficacy when used in the second-line setting.
