UNLABELLED: The Anthracyclines/Taxanes combination is often used in adjuvant and advanced breast cancer. PURPOSE: To evaluate the toxicity and pathological response of sequential epidoxorubicin/paclitaxel combination as primary chemotherapy for T > 3 cm and T4 breast cancer patients. PATIENTS AND METHODS: Forty-eight patients with T2 > 3 cm, T3 and T4 breast tumours were treated with Epidoxorubicin (90 mg/m2, i.v.) on day one and paclitaxel (200 mg/m2 over 3 hours) on day 2 every 21 days for four courses. After the fourth cycle the patients underwent modified radical mastectomy or quadrantectomy plus axillary lymph node dissection followed by six courses of intravenous CMF regimen (days 1 and 8, every 4 weeks). Radiotherapy was given to patients undergoing conservative surgery or with T4 cancers. Tamoxifen was administered in ER or PgR positive patients. RESULTS: Out of the 48 patients enrolled into this trial, 43 were evaluable for toxicity and pathological response. Primary chemotherapy with epidoxorubicin and paclitaxel was well tolerated: no heart toxicity was observed during primary chemotherapy and follow-up. Primary toxicity consisted of myalgia, grade 1 neuropathy and grade 3 alopecia. Disappearance of invasive tumours in the breast with node negative was observed in 11.6% of patients: pathological partial response was shown in 56% of patients. On the whole major pathological response was achieved in 67% of our series: in the remaining 33% we found a stable disease or a size reduction less than 50%. No progressive disease was observed. Conservative surgery was performed in 64.5% of T2 and T3 tumours. CONCLUSION: These preliminary data showed that the epidoxorubicin/paclitaxel combination was safe and effective as primary chemotherapy for patients with T > 3 cm and T4 breast cancer patients.
