Purpose

Breast cancer is the most common form of cancer among women. For patients candidated for adjuvant chemotherapy and endocrine therapy the optimal timing for their has not been clearly defined yet.

Detailed Description

      Breast cancer is the most common form of cancer among women in North America, Europe and
      Latin America. Because nearly 80% of breast cancers are endocrine-responsive tumors, the
      majority of patients candidates for adjuvant chemotherapy (CT) are also candidates for
      endocrine therapy (ET). The optimal timing (i.e. concomitant vs sequential administration)
      for the integration of these two treatments has not been clearly defined yet.

      In patients with hormone receptor positive early stage breast cancer who are candidates to
      adjuvant chemotherapy and endocrine therapy, the optimal timing for the integration of these
      two treatment modalities has not been clearly defined yet.

Eligibility Criteria

        Inclusion Criteria:

          -  Women with histological diagnosis of invasive breast cancer completely removed by
             surgery, any T, any N.

          -  Postmenopausal status defined by at least one of the following conditions:

               1. Aged ≥ 60

               2. Aged 45-59 and satisfying one or more of the following criteria:

                    -  amenorrhea for ≥12 months and intact uterus;

                    -  amenorrhea for <12 months and follicle-stimulating hormone (FSH) within the
                       postmenopausal range, including:

                         -  pts with hysterectomy

                         -  pts who have received hormone replacement therapy (HRT)

                         -  pts with chemotherapy-induced amenorrhea

               3. bilateral oophorectomy at any age >18 years.

          -  Primary tumor positive for Estrogen Receptors (ER) and/or Progesteron receptors (PgR)
             (≥1% tumor cells positive by immunohistochemistry or ≥ 10 fmol/mg cytosol protein by
             ligand binding assay).

          -  Patients who are prescribed 5 years of endocrine therapy with an aromatase inhibitors
             (AI)

          -  Indication for adjuvant chemotherapy- Patients with HER-2 positive tumors are eligible
             provided that they are prescribed trastuzumab according to registered schedule.

          -  Signed informed consent.

        Exclusion Criteria:

          -  HRT currently assumed or during the month before randomization

          -  Recurrent or metastatic disease

          -  HER-2 positive tumors if treatment with trastuzumab is considered not
             appropriate/feasible

          -  Concurrent illness that contraindicate adjuvant endocrine treatment and/or
             chemotherapy

          -  Patients who have received Tamoxifen as part of any breast cancer prevention trial

          -  Previous history of invasive breast cancer or other invasive malignancy within the
             previous 10 years, other than squamous or basal cell carcinoma of the skin or
             carcinoma in situ of the cervix, adequately cone biopsied

          -  Concomitant severe disease which would place the patient at unusual risk

          -  Concurrent treatment with experimental drugs

          -  Patients treated with systemic investigational drugs within the past 30 days
      
Maximum Eligible Age:N/A

Healthy Volunteers:No

Primary Outcome Measures

Measure:Disease- free Survival (DFS)
Time Frame:up to 15 years
Safety Issue:
Description:the primary outcome indicator will be the so called DFS, defined as time elapsing between the date of randomization and the date of one of the following events, whichever occurs first, assessed up to 15 years: Local Recurrence of disease Regional recurrence of disease Distant recurrence of disease Contralateral invasive or intraductal breast cancer Second primary malignancy other than breast Death for any cause

Secondary Outcome Measures

Measure:Overall Survival (OS)
Time Frame:time between the date of randomization up to the date of death for any cause, assessed up to 15 years.
Safety Issue:
Description:
Measure:Translational Study: genomic analysis
Time Frame:up to 15 years
Safety Issue:
Description:Expression of genes associated with ER and Ki67 expression will be analyzed by Real Time polymerase chain reaction (PCR) on RNA extracted from formalin-fixed paraffin embedded (FFPE) sections of tumors classified as intermediate risk by clinical and pathological variables (stage I-II, G2, hormone receptors positive) and will be correlated with disease free survival.
Measure:Translational Study: epigenetic analysis
Time Frame:up to 15 years
Safety Issue:
Description:miRNA expression analysis by real time PCR and DNA methylation analysis by pyrosequencing will be assessed on FFPE sections of tumors classified as intermediate risk by clinical and pathological variables (stage I-II, G2, hormone receptors positive)
Measure:Translational Study: proteomic analysis
Time Frame:up to 15 years
Safety Issue:
Description:The different proteomic profiles identified in FFPE sections of hormone receptors positive G2 tumors will be correlated with DFS
