A Prospective, Open and Unicentric Phase II Clinical Trial of Docetaxel Combined With Oxaliplatin for Triple Negative Local Advanced Breast Cancer Patients (TNLABC)
Eligibilty Female adults(>18 years old) were eligible if they had histologically or
cytologically confirmed stage IIIb or IIIc TNLABC that had not been treated with any
systemic treatment. Patients also had Eastern Cooperative Oncology Group(ECOG) Performance
status of 0 or 1, absolute neutrophil count (ANC)>1500/mm3,hemoglobin >8.0g/dL, and platelet
count >100,000/mm3,creatinine<2.5 times the upper limit of normal(ULN)), transaminases<2.5
times ULN or alkaline phosphatase<4 times ULN if transaminases was normal, and total
bilirubin <2.5 times ULN. Exclusion criteria were active infection, pregnancy, other primary
malignancy (except in situ carcinoma of cervix or adequately treated nonmelanomatous
carcinoma of the skin), any documented distant metastasis and uncontrolled systemic
diseases.
This study protocol was approved by institutional ethic review boards and conducted
according to guidelines for good clinical practice and the Helsinki Declaration.All patients
provided written informed consent.
Study design and treatment plan This was a prospective, open and unicentric phase II
clinical study. All chemotherpy was administered intravenously on an outpatient basis. The
patients received dexamethasone 7.5mg orally twice a day for 3 days before the day of
chemotherapy. On day 1, docetaxel 75mg/m2 was infused over 60 minutes as well as oxaliplatin
130mg/m2 was infused over 120 minutes on day 2. Thirty minutes before chemotherapy,
premedication consisted of a 5-hydroxytryptamine3(HT3) receptor antagonist. Furthermore,
Vitamin C 2g and Vitamin B2 200mg were followed immediately after the chemotherapy.
Treatment was administered every 21 days for a maximum of four cycles or until disease
progression or unacceptable toxicity.The prophylactic use of a colony-stimulating factor
(CFS) was not permitted in the first cycle.
An initial diagnosis of unilateral primary breast cancer without distant metastases, at
least 7 months of follow-up information for disease recurrence and death and triple receptor
negative for estrogen receptor (ER), progesterone receptor (PR), Her2 were included as
pre-treatment evaluation. Moreover tumor size, number of involved axillary lymph nodes
(ALN), clinical stage and biomarkers such as Cathepsin-D, P53, nm23, PS2 and PCNA, were
recorded as available information for further analysis. In the procedure of neoadjuvant
chemotherapy, weekly or biweekly complete blood cell counts, physical examination,
electrocardiogram (EKG), liver and rental function tests should be repeated. Tumor size was
assessed by magnetic resonance imaging (MRI) every two cycles or when the clinical signs
suggested disease progression as well as before the chemotherapy. Tumor response was
determined by response evaluation criteria in solid tumors (RECIST). Complete and partial
response (CR and PR) should be confirmed on two assessments performed at least four weeks
apart.
