Doxorubicin and Cyclophosphamide (AC) Followed by Weekly Docetaxel as Neoadjuvant Treatment of Breast Cancer Patients

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00129376
Recruitment Status : Completed
First Posted : August 11, 2005

Spanish Breast Cancer Research Group

Brief Summary:

Treatment consists of 4 AC cycles followed by 2 weekly docetaxel cycles (12 infusions).

The pathological complete response rate obtained in previous studies is around 12%. The expected pathological complete response rate in this study is 25%. With an alpha error of 0.05 and a beta error of 0.2, and following Simon´s 2 phase test, 19 patients are needed initially. With 2 pathological complete responses, patient recruitment will continue until approximately 61 patients are recruited. Twelve pathological complete responses are needed to confirm the study hypothesis.

Arm Intervention/treatment
Experimental: Doxorubicin+cyclophosphamide - Docetaxel
Patients received doxorubicin (60 mg/m2) and cyclophosphamide (600 mg/m2), both in a short intravenous infusion, every three weeks for four cycles. Later, docetaxel (36 mg/m2) was administered an intravenous infusion, weekly for six weeks followed by a 2-week resting period (8-week cycle).
Drug: docetaxel
Other Names:
  • doxorubicin
  • cyclophosphamide

Primary Outcome Measures :
  1. Pathological complete response [ Time Frame: up to 24 weeks ]
    Defined by the Miller & Payne criteria

Secondary Outcome Measures :
  1. Clinical response rate [ Time Frame: up to 24 weeks ]
    The clinical response is measured according to the RECIST criteria.

  2. Toxicity [ Time Frame: up to 12 weeks ]
    Is measured according to the scale of the NCI version 2.0

  3. Disease-free survival [ Time Frame: From date of randomization until the date of first documented progression (if it is applicable), assessed up to 72 months ]
    Interval from the date of registration in the study to the date of local, regional or metastatic recurrence or the date on which the second primary cancer manifests or death occurs for any reason, depending on the circumstance that occurs first .

  4. Overall survival [ Time Frame: From date of randomization until the date of death from any cause, assessed up to 72 months ]
    Interval from the date of registration in the study to the date in which the death occurs for any reason.

  5. Molecular markers and correlation with response [ Time Frame: through study completion, an average of 2 years ]
    The predictive response markers will be determined by the usual techniques

Ages Eligible for Study:   18 Years to 70 Years   (Adult, Senior)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Written informed consent.
  • Patients with breast cancer stages II and IIIA, with histological diagnoses as per true-cut or open biopsy.
  • Negative extension study, including bilateral mammography, thoracic x-ray, computed tomography (CT)-scan or abdominal echography and bone scintigraphy.
  • Analysis of hormone receptor status in primary tumour. It is highly recommended to obtain a tumour tissue sample before start of treatment, and after definitive surgery. These samples will be analysed centrally by GEICAM.
  • Age >= 18 and <= 70 years old.
  • Performance status as per Karnofsky index >= 80.
  • Minimum life expectancy of 6 months.
  • Electrocardiogram (EKG) 12 weeks before registration to the study. If abnormalities are suspected, cardiac function must be assessed by left ventricular ejection fraction (LVEF).
  • Haematology: neutrophils >= 2.0 x10^9/l; platelets >= 100 x10^9/l; hemoglobin >=10 g/dl.
  • Hepatic function: total bilirubin <= 1 x upper normal limit (UNL); SGOT and SGPT <= 2.5 x UNL; alkaline phosphatase <= 5 x UNL.
  • Renal function: creatinine <= 1.5 x UNL; creatinine clearance >= 60 ml/min.
  • Patients able to comply with study requirements.
  • Negative pregnancy test.
  • Adequate contraceptive method during the study and up to 3 months after definitive surgery.

Exclusion Criteria:

  • Previous systemic therapy for breast cancer treatment.
  • Previous treatments with anthracyclines or taxanes for any malignancy.
  • Previous radiotherapy for breast cancer.
  • Bilateral invasive breast cancer.
  • Pregnant or lactating women.
  • Previous motor or sensorial neurotoxicity grade >=2.
  • Other serious pathologies: congestive heart failure or angina pectoris; history of myocardial infarction in the previous year; uncontrolled hypertension (HT) or high risk arrhythmias.
  • History of neurological or psychiatric impairment, precluding patients from providing free informed consent.
  • Active infection.
  • Active peptic ulcer; unstable diabetes mellitus.
  • History of previous or current malignancies other than breast cancer, except for basal skin carcinoma, cervical in situ carcinoma, other tumour diagnosed and treated more than 10 years before, ductal carcinoma in situ (DCIS) or lobular carcinoma in situ (LCIS).
  • Chronic treatment with corticoids unless the treatment started > 6 months before registration to the study, and low doses are administered.
  • Substitutive hormonal therapy. This treatment must be interrupted before inclusion in the study.
  • Concomitant treatment with other investigational products or administration in the 30 previous days.
  • Males.
