Weekly short infusion of taxotere at a 4 week cycle in Chinese patients with advanced NSCLC who have failed or relapsed after the frontline platinum-based non-taxane chemotherapy--a Phase II trial.
BACKGROUND
This Phase II study was conducted to evaluate the efficacy and toxicity of weekly docetaxel at a 4 week cycle in second-line therapy for patients with advanced non-small cell lung cancer (NSCLC) who failed to respond or relapsed after the frontline platinum-based, non-taxane regimen.


METHODS
Patients with histologically confirmed and progressive NSCLC after one platinum-based, non-taxane regimen were eligible for this study. Performance status of 0-2 and adequate organ function were required. Patients were treated with docetaxel 40 mg/m(2)/week for three consecutive weeks then following 1 week of rest. Cycles were repeated every 4 weeks for a maximum total of six cycles. Docetaxel was administered intravenously for 30 min with dexamethasone premedication.


RESULTS
Fifty-three patients were eligible for this study. Hematologic toxicity was very mild and with the major toxicity of anemia. Non-hematologic toxicities were modest, Grades 3-4 mucositis, diarrhea and peripheral neuropathy occurred in 6-13% of patients and caused dose modifications. Fatigue (48%) was common but not severe with only 6% of Grades 3-4 toxicity. The overall response rate (ORR) was 13% [95% confidence interval (CI), 3.9-23%]. The median survival time (MST) for all patients was 25.0 weeks (95% CI, 12.7-37.3), and the 1 year survival was 31% (95% CI, 17-58%). For patients with PS 0-1, MST was 29.7 weeks and 1 year survival was 36%.


CONCLUSIONS
Weekly docetaxel appeared to be well tolerated as second-line therapy for patients with NSCLC. The efficacy for this regimen was comparable with the standard 3 week schedule but hematologic toxicity was markedly reduced. A schedule of three consecutive weeks, with a 1 week break, may diminish the frequency of fatigue and diarrhea when compared with a schedule of six consecutive weeks.
