Activity of docetaxel in platinum-treated non-small-cell lung cancer: results of a phase II multicenter trial.
OBJECTIVE
Although several new chemotherapeutic agents are promising as primary therapy in non-small-cell lung cancer (NSCLC), few have demonstrated activity in platinum-refractory disease. Based on encouraging results reported in two single-institution studies of docetaxel in this setting, we performed a multicenter phase II trial evaluating this novel taxane in previously treated NSCLC patients prospectively categorized by platinum response status.


METHODS
Eighty patients with NSCLC previously treated with platinum-based chemotherapy received docetaxel at a dose of 100 mg/m(2) intravenously over 1 hour, repeated every 21 days, accompanied by dexamethasone 8 mg orally twice daily for 5 days. Forty-seven patients (59%) were defined as platinum-refractory based on response status to prior therapy.


RESULTS
The median number of cycles delivered per patient was four (range, one to 21 cycles). Partial response was observed in 13 (16%) of 80 of patients, with similar response rates in platinum-sensitive and platinum-refractory patients. The median survival time was 7 months, and the 1-year survival rate was 25%. Docetaxel was relatively well tolerated in this previously treated population. Grade IV neutropenia was common in patients (77%) but typically of brief duration. Febrile neutropenia was observed in 11 patients (14%), with no fatal infections. Severe fluid retention was rare (4% of patients).


CONCLUSIONS
This multicenter phase II trial confirms antitumor activity and encouraging survival with docetaxel therapy in platinum-treated and platinum-refractory NSCLC. To validate these results, a phase III trial randomizing platinum-treated patients to docetaxel or best supportive care is underway.
