Vinorelbine versus paclitaxel for patients with advanced non-small cell lung cancer (NSCLC) and a performance status of 2

The purpose of this study was to compare two single agents paclitaxel (intravenous) versus vinorelbine (oral) in non-small cell lung cancer (NSCLC) patients with performance status (PS):2.

The patients were randomized to receive either oral vinorelbine 60 mg/m(2) on days 1, 8, 15 every 4 weeks for 4 cycles (group A) or paclitaxel 90 mg/m(2) intravenously for 1 h on days 1, 8, 15 every 4 weeks for a total of 4 cycles (group B).

Among the 74 eligible patients (36 in arm A and 38 in arm B) in arm A, two (6%) had a partial response (95% CI, 0.7-18.7) and 5 (14%) had stable disease (95% CI, 4.7-29.5). In arm B, five (13%) had a partial response (95% CI, 4.4-28.1) and 7 (18%) had stable disease (95% CI, 7.7-34.3). No significant difference was found in terms of clinical benefit between the two groups after two cycles of treatment except for appetite in favour of paclitaxel (p=0.01). Median survival was 3.1 months (95% CI, 2.2-4.0) for arm A and 5.1 months (95% CI, 2.7-7.6) for arm B (p=0.95). Toxicity was mild and only alopecia was more profound in the patients of arm B (p=0.008).

No significant difference was found in clinical benefit between PS:2 NSCLC patients treated with either vinorelbine or paclitaxel.
