Abstract:
Objective To evaluate the efficacy and survival rate of neoadjuvant chemotherapy with docetaxe and pirarubicin in triple negative breast cancer (TNBC).Methods Total 51 breast cancer patients were divided into TNBC group (n =26,including 16 of stage Ⅱ and 10 of stage Ⅲ patients) and non-TNBC group (n =25,including 14 of stage Ⅱ and 11 of stage Ⅲ patients).All patients received a median of 4 treatment cycles with TAC regimen [docetaxe 75 mg/m2 on day 1,pirarubicin 40 mg/m2 on day 1 and cyclophosphamide (CTX) 500 mg/m2 on day 1 of each 21 day cycle].The efficacy of treatment and survival rate of two groups were evaluated.Results In TNBC group,9 out of 26 (34.62 ％) patients achieved clinical complete response (cCR),and 14 (53.85 ％) had partial response (cPR).Overall,88.46 ％ of TNBC patients had clinical response and 26.92 ％ (7/26) showed pathology complete response (pCR).In non-TNBC group,6 (24.00 ％) patients reached cCR and 8 (32.00 ％) showed cPR.The overall response rate was of 56.00 ％,and 4 (16.00 ％) patients achieved pCR.The overall 3-year survival rates in TNBC and non-TNBC groups were 73.08 ％ and 88.00 ％,respectively,indicating a poorer prognosis of TNBC.The 5-year survival rates of TNBC patients with and without pCR were 88.89 ％ and 47.06 ％,respectively.Conclusion TAC regimen improves the prognosis for locally advanced TNBC,indicating that the neoadjuvant chemotherapy is effective and safe for TNBC patients.
