A phase II study of weekly paclitaxel as second-line chemotherapy for advanced gastric Cancer (CCOG0302 study).
BACKGROUND
Although paclitaxel was given triweekly in phase II trials prior to its approval for gastric cancer in Japan, it is currently more often delivered by a weekly schedule in the second-line setting.


METHODS
A phase II trial with response rate as the primary end-point was conducted. Patients with metastatic or unresectable gastric adenocarcinoma who had measurable lesions and had disease progression with the front-line chemotherapy were treated by weekly administration of paclitaxel at a dose of 80 mg/m2.


RESULTS
Forty-five patients were accrued and 44 were assessable for response. Partial responses were observed in 7 patients (16%). Stable disease was documented in further 14 patients (48%). Median progression-free survival of all patients enrolled was 2.6 months and median overall survival was 7.8 months. Toxicity was mild and manageable, the most frequent > or = grade 3 toxicity being neutropenia occurring in 16% of the patients.


CONCLUSIONS
With modest response rate, favorable toxicity profile, and progression-free or overall survival similar to those of more intense combination regimens, weekly paclitaxel remains a rational therapeutic option for gastric cancer refractory to the first-line chemotherapy.
