Phase II study of gemcitabine plus docetaxel in advanced pancreatic cancer: a Hoosier Oncology Group study.

OBJECTIVE

To determine the response rate, duration of response and survival with weekly gemcitabine plus docetaxel in metastatic or unresectable pancreatic cancer.

METHODS

Forty patients were enrolled, and 38 patients were evaluable for survival and toxicity. Thirty-seven patients were evaluable for response. Nine patients (24%) had locally advanced disease and 29 (76%) had metastatic disease at the time of enrollment. Median Eastern Cooperative Oncology Group performance status was 1. Patients received gemcitabine 750 mg/m(2) i.v. and docetaxel 35 mg/m(2) i.v. weekly for 3 out of 4 weeks for a maximum of 6 cycles.

RESULTS

Patients received a median of 4 cycles (range 1-6) of chemotherapy. An objective response was obtained in 10 patients (27%) with a median duration of 17 weeks. Median survival was 7 months, and 1-year survival was 19.3%. Eight patients experienced at least one form of grade 4 toxicity and 27 patients experienced at least one type of grade 3 toxicity.

CONCLUSIONS

The combination of gemcitabine and docetaxel is a well-tolerated regimen with clinical efficacy. The ultimate role of this combination versus single-agent gemcitabine can only be determined by a randomized phase III trial.
