Summary:

      Primary objective :

        -  To compare disease-free survival after treatment with docetaxel in combination with
           doxorubicin and cyclophosphamide to doxorubicin and cyclophosphamide followed by
           docetaxel in operable adjuvant breast cancer HER2neu negative patients with positive
           axillary lymph nodes.

      Secondary objectives :

        -  To compare toxicity and quality of life between the 2 above-mentioned arms.

        -  To evaluate pathologic and molecular markers for predicting efficacy.
    

Eligibility criteria:

        Inclusion Criteria :

          -  Histologically proven breast cancer. Interval between definitive surgery that includes
             axillary lymph node dissection and registration is less than or equal to 60 days. A
             central pathology review may be performed post randomization for confirmation of
             diagnosis and molecular studies.

          -  Definitive surgical treatment must be either mastectomy, or breast conserving surgery
             with axillary lymph node dissection for operable breast cancer (T1-3, Clinical N0-1,
             M0). Margins of resected specimen from definitive surgery must be histologically free
             of invasive adenocarcinoma and Ductal Carcinoma In Situ (DCIS). Lobular carcinoma
             in-situ does not count as a positive margin.

          -  Histologic examination of the tumor: Invasive adenocarcinoma with at least one
             axillary lymph node (pN1) showing evidence of tumor among a minimum of six resected
             lymph nodes.

          -  Tumor must show negative HER2 neu proto-oncogene overexpression by FISH (Fluorescence
             In Situ Hybridization). Confirmation of non overexpression will be centrally assessed
             by authorized BCIRG (Breast Cancer International Research Group) laboratories prior to
             randomization.

          -  Estrogen and/or progesterone receptor analysis performed on the primary tumor prior to
             randomization. Results must be known at the time of randomization.(Note: Patients
             whose tumor is estrogen receptor negative with progesterone receptor status unknown or
             undetermined, must have the progesterone receptor assayed in order to determine
             hormonal receptor status. Patients whose tumor is progesterone receptor negative with
             estrogen receptor status unknown or undetermined, must have the estrogen receptor
             assayed in order to determine hormonal receptor status).

          -  Karnofsky Performance status index > 80%.

          -  Normal cardiac function must be confirmed by LVEF (Lef Ventricular Ejection Fraction)
             i.e. MUGA (Multi Gated Acquisition) scan or echocardiography and ECG within 3 months
             prior to registration. LVEF result must be above or equal to the lower limit of normal
             for the institution. The ECG results must be within normal limits or show no
             significant abnormalities.
