BACKGROUND: Gemcitabine and docetaxel have been claimed to be active single agents in advanced pancreatic cancer. We determined the maximum tolerable dose of docetaxel combined with a weekly fixed dose of gemcitabine and assessed the activity of this combination in advanced pancreatic cancer.
PATIENTS AND METHODS: Phase I. Patients were treated with gemcitabine on days 1 and 8, every three weeks, at a fixed dose of 1,000 mg/m2; docetaxel was given at escalating doses starting from 70 mg/m2 on day 8. Phase II. In accord with the optimal two-stage phase II study design, 18 patients were treated with gemcitabine (1000 mg/m2) and the maximum tolerable dose of docetaxel (70 mg/m2).
RESULTS: Phase I. Dose-limiting toxicities occurred at the second dose level of docetaxel (80 mg/m2), with all three patients developing grades 3 or 4 neutropenia. Consequently, the dose tested in the phase II study was 70 mg/m2. Phase II. In the 18 patients enrolled in the study, we registered only one partial response. The time to progression was 3 months,and the median treatment survival was 5.4 months. Grade 3-4 toxicities consisted of neutropenia (three episodes) and thrombocytopenia (two episodes). Furthermore, 10 patients complained of grade 3 fatigue.
CONCLUSIONS: The addition of docetaxel to gemcitabine does not appear to be useful in advanced pancreatic cancer, since gemcitabine alone achieves similar results.
