| Popis: | To assess the efficacy and safety of primary systemic treatment with doxorubicin and paclitaxel in patients with early breast cancer. Forty patients with newly diagnosed, histologically confirmed breast cancer (T2, N0–1, M0) received primary chemotherapy with doxorubicin (60 mg/m2) and paclitaxel (200 mg/m2) in 3-week intervals for up to four courses. A total of 151 cycles were administered. The clinical response rate as assessed by sonographic measurement was 70%, and complete remissions of the primary tumor occurred in two patients. Eight patients (20%) had histologically confirmed complete responses. Predominant toxicity was myelosuppression with grade 3/4 neutropenia in 70% of patients. Non-hematological toxicity was generally moderate. Grade 4 non-hematological toxicities were not observed and grade 3 toxicity was reported with alopecia (98%) and stomatitis (10%). The combination of doxorubicin and paclitaxel is safe and highly active in patients with early breast cancer. The evaluated schedule is suitable for phase III studies. |
