The purpose of this study was to determine the response rate of the gemcitabine/epirubicin/paclitaxel combination (GET) and its feasibility as induction chemotherapy before high-dose consolidation treatment in patients with metastatic breast cancer. Patients received gemcitabine 1,000 mg/m2 on days I and 4, epirubicin 90 mg/m2 on day 1, and paclitaxel 175 mg/m2 on day I every 3 weeks for up to eight courses. After six courses of GET, responding patients or those with stable disease entered a high-dose chemotherapy program. All 36 enrolled patients were evaluated for toxicity and response. The GET combination was well tolerated, with myelosuppression the being most common toxicity; grade 4 neutropenia was reported in 56% of patients. The overall response rate was 89% (95% confidence interval, 73.4% to 96.9%), with a 28% complete response rate. The high-dose chemotherapy program resulted in a response rate of 92% and a complete response rate of 44%. As a result of the promising activity demonstrated in this phase II study with GET and following high-dose chemotherapy, three related studies are planned: an in vitro study evaluating the possible synergism of paclitaxel and gemcitabine, a phase III study comparing GET with epirubicin/paclitaxel in metastatic breast cancer, and a phase II trial evaluating GET in patients with operable breast cancer.
