Abstract

Triple-negative breast cancers comprise about 20 % of breast cancers. They have poor prognosis and have no standard therapy. The aim of this study was to evaluate pathologic complete response (pCR), progression-free survival (PFS), and overall survival (OS) in patients with TNBC treated with neoadjuvant platinum-based chemotherapy. This is a retrospective study of one hundred and forty-four women with TNBC treated with neoadjuvant platinum-containing chemotherapy for locally advanced breast cancer at the University of Miami between January 1, 1999, and January 1, 2011. The medical record was reviewed to obtain data on clinical characteristics, including ethnicity, race, age, clinical stage, treatment regimen, and vital status. This study was approved by the University of Miami IRB. All patients had locally advanced breast cancer with at least one of the following features at presentation: T3, T4, N2, and N3. The mean tumor size by palpation was 9.4 cm. The clinical T-stage at presentation was 1.4 % T1, 8.3 % T2, 52.8 % T3, and 37.5 % T4 (19.4 % T4d). The nodal status by physical exam at presentation was 23 % N0, 37.5 % N1, 34 % N2, and 5.5 % N3. pCR in breast and axilla was seen in 31 %. PFS and OS were 55 and 59 %, respectively, at 7 years. Cisplatin offered a survival advantage over carboplatin in both PFS (P = 0.007) and OS (P = 0.018). Node positivity was the most important predictor of survival. Cisplatin/docetaxel neoadjuvant therapy was well tolerated and an effective therapy in locally advanced TNB.
