Objective: To evaluate the effectiveness and tolerability of neoadjuvant chemotherapy with weekly paclitaxel in combination with weekly carboplatin area under curve 2 followed by anthracycline chemotherapy. Patients and methods: This is a retrospective review of electronic medical records of patients (N = 32) with stage 1c–III triple-negative breast cancer. Patients received neoadjuvant chemotherapy with paclitaxel 80 mg/m2 once per week for 12 weeks in combination with carboplatin area under curve 2 once per week for 12 weeks (wP + wCb), followed by a standard anthracycline regimen including either doxorubicin 60 mg/m2 and cyclophosphamide 600 mg/m2 every 2 or 3 weeks, or epirubicin 90 mg/m2 and cyclophosphamide 600 mg/m2 every 3 weeks for four cycles with myeloid growth factor support. Results: Most patients (91%) received all 12 cycles of wP + wCb, and 88% received all four planned cycles of anthracycline chemotherapy. Of the patients, 84% completed all planned therapies. The complete pathologic response rate was 60%. In terms of hematologic toxicity, 96% of the patients experienced grade ≥3 leucopenia, 40% grade ≥3 anemia, and 15% grade ≥3 thrombocytopenia, and neutropenic fever was seen in 22% of the patients. Conclusion: The combination of neoadjuvant chemotherapy with wP + wCb before anthracycline chemotherapy can be tolerated by patients with triple-negative breast cancer. Complete pathologic response rates were comparable with those historically seen. Careful selection of patients is fundamental as this regimen is associated with a high incidence of hematologic toxicity. Keywords: Triple negative breast cancer, Neoadjuvant chemotherapy
