Multicenter phase II trial of docetaxel and carboplatin in patients with stage IIIB and IV non-small-cell lung cancer.
OBJECTIVE
To evaluate the safety and efficacy of docetaxel and carboplatin as first-line therapy for patients with advanced non-small-cell lung cancer (NSCLC).


METHODS
In this multicenter, phase II trial, 33 patients with previously untreated stage IIIB (n = 8) or IV (n = 25) NSCLC received intravenous infusions of docetaxel 80 mg/m2 followed immediately by carboplatin dosed to AUC of 6 mg/ml/min (Calvert's formula) every three weeks. Patients also received dexamethasone 8 mg orally twice daily for three days beginning one day before each docetaxel treatment. Filgrastim was not allowed during the first cycle and was added only if a patient experienced febrile neutropenia or grade 4 neutropenia lasting > or = 7 days.


RESULTS
There were 1 complete and 11 partial responses for an objective response rate of 43% (95% CI: 24%-63%) in 28 evaluable patients and 36% (95% CI: 20%-55%) in the intent-to-treat population. The median duration of response was 5.5 months (range 3.0-12.5 months). The median survival was 13.9 months (range 1-35+ months); one-year survival was 52%. The most common toxicity was hematologic, which included grade 4 neutropenia (79% of patients and 7% percent of cycles) and febrile neutropenia (15% of patients); there were no episodes of grade 3 or 4 infection. The most common severe nonhematologic toxicities were asthenia (24%) and myalgia (12%); there were no grade 3 or 4 neurologic effects.


CONCLUSIONS
The combination of docetaxel and carboplatin has an acceptable toxicity profile and is active in the treatment of previously untreated patients with advanced NSCLC. This combination is being evaluated in a randomized phase III trial involving patients with advanced and metastatic NSCLC.
