A phase II study of epirubicin, cisplatin and capecitabine as neoadjuvant chemotherapy in locally advanced or inflammatory breast cancer

• Aim: To assess the efficacy and safety of epirubicin, capecitabine and cisplatin (EXC) combination therapy in locally advanced breast cancer (LABC) and investigate the predictive value of selected biomarkers. Methods: Newly diagnosed LABC patients received four 3-weekly cycles of neoadjuvant EXC (epirubicin 60 mg/m2 day 1; capecitabine 1000 mg/m2 bid, days 1-14; cisplatin 60 mg/m2day 1) and two cycles of post-operative EXC. Results: Eight (17%) of 48 patients had inflammatory breast cancer. Overall response rate was 74% (95% CI: 59-86%), including complete responses in 13% (95% CI: 5-26%). Nine (22%; 95% CI: 11-38%) of 41 patients undergoing surgery achieved pathologic complete response (pCR), giving a pCR rate of 19% (95% CI: 9-33%) in the intent-to-treat population. Haematological toxicity was manageable. The most problematic toxicities were chemotherapy-induced nausea/vomiting and hypercoagulative disorders. None of the biomarkers investigated, including HER2, predicted response. Conclusion: EXC showed high efficacy in LABC, with high clinical response and pCR rate. Nausea and vomiting were unexpectedly frequent, and more aggressive prophylaxis and management of these side effects is recommended in future studies of this combination.
