A phase II study of weekly paclitaxel and carboplatin in previously untreated patients with advanced non-small-cell lung cancer.
OBJECTIVE
Both paclitaxel (P) and carboplatin (C) have a significant activity in non-small cell lung cancer (NSCLC). Weekly administration of P is active, is dose intense, and has a favorable toxicity profile. To evaluate the efficacy and toxicity of weekly P and C in advanced-stage NSCLC, we initiated this phase II study in patients with advanced NSCLC (III B with pleural effusion and stage IV).


METHODS
Eligible patients were treated with paclitaxel 100 mg/m2 intravenously (iv) over 1 h followed by carboplatin AUC 2 iv over 30 min. This treatment was administered weekly for 3 of every 4 wk until disease progression or intolerable toxicities.


RESULTS
Of the 30 patients enrolled in the study, one patient did not meet the eligibility criteria. Of the remaining 29 patients, 6 did not complete at least two cycles of treatment and hence were not assessable for response. The overall response rate was 43.5% (10/23) (all partial responses). An additional 43.5% had stable disease. The median time to progression was 162 d and the median duration of response was 169 d. Overall survival at 1 yr on intent-to-treat analyses was 44% and median survival was 10.8 mo. We observed the following grade 3/4 toxicities: hypersensitivity to paclitaxel (13%), hypersensitivity to carboplatin (3%), neutropenia (31%), thrombocytopenia (7%); 31% experienced grade 1 neuropathy and 17% experienced grade 2 neuropathy.


CONCLUSIONS
We conclude that weekly paclitaxel and carboplatin is active and very well tolerated in patients with advanced NSCLC.
