Numerous trials have shown that the pharmacokinetic interferences of epirubicin (Ellence)/paclitaxel (Taxol) combinations produce less pharmacodynamic effect than doxorubicin/paclitaxel regimens. Paclitaxel is more easily combined when infused over 3 (as compared to 24) hours; the administration of optimal doses of both agents is important. Based on these findings, a phase II study was performed to evaluate the feasibility and activity of the combination of gemcitabine (Gemzar), epirubicin, and paclitaxel as first-line therapy in advanced breast cancer. Patients received gemcitabine at 1,000 mg/m2 on days 1 and 4, plus epirubicin at 90 mg/m2 on day 1, plus paclitaxel at 175 mg/m2/d on day 1 every 21 days. After six courses, patients less than 60 years old and in complete or partial remission or stable disease were treated with high-dose chemotherapy as consolidation treatment. The overall response rate was 92%, with 31% complete responses; 25 patients received high-dose chemotherapy, achieving a final overall response rate of 97%, with 47% complete responses. At a median follow-up of 25 months, median progression-free survival is 21 months. Grade 4 neutropenia was observed in 64% of patients. Other hematologic toxicities were mild. Mild to moderate peripheral neuropathy was experienced by 39% of patients; grade 2 or 3 mucositis occurred in 25% and 17% of patients, respectively. Based on these results, a multicenter trial has been started in seven Italian centers to confirm the feasibility of this regimen.
