Brief Summary:

This is a prospective, open-label, randomized phase III study. Patients will be stratified as per investigational site, previous adjuvant chemotherapy (anthracyclines versus anthracyclines plus taxanes), and number of affected axillary lymph nodes (0, 1-3, >= 4). Node negative patients must present a tumour size > 2 cm to be eligible. At least 6 lymph nodes must be analysed to confirm the number of affected nodes. Patients will be randomised to receive: 8 courses of capecitabine 1000 mg/m2 by mouth, twice a day (p.o. bid) for 14 days, followed by a 7 day rest versus observation.

Tissue samples must be analysed by a central laboratory, to confirm estrogen receptor (ER), progesterone receptor (PgR), human epidermal growth factor receptor-2 (HER2), cytokeratins CK 5/6 and epidermal growth factor receptor (EGFR) status.

The following data were obtained from the database of the "El Alamo" project. One thousand six hundred and twenty-seven (1,627) in total were considered during the years 1990 to 1997. The population is formed of patients with operable breast cancer, with surgery, positive nodes, and negative hormone receptors, or negative nodes, negative hormone receptors and T2-3 tumors.

For these patient groups, estimated 5-year disease-free survival is 64.72%. Assuming an exponential distribution, the aim is to detect an increase of 64.72% to 73.7% in 5 years Disease Free survival rate corresponds to a Hazard Ratio of 0.701 and a risk reduction of about 30%, with a power of 80% using a two-tailed log-rank test at 0.05 and whereas 4 years of recruitment period and 3 years of follow-up period. We would need 255 events, 834 patients without considering any dropouts.

Considering a drop-out rate of 5% post-randomization, the final sample size will be 876 patients, 438 per treatment arm.

The sample size calculation was performed by the program package EAST version 5.2.

Primary Outcome Measures :
  1. Disease free survival [ Time Frame: At the end of Cycle 8 (each cycle is 28 days) ]

Secondary Outcome Measures :
  1. Overall survival [ Time Frame: 5 years ]

Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Written informed consent.
  • Histological diagnoses of operable invasive adenocarcinoma of the breast (T1-T3). Tumours must be HER2 negative. Time window between end of adjuvant chemotherapy and study randomization must be less than 8 weeks. In patients receiving adjuvant radiotherapy, time window allowed between last session and randomisation is 4 weeks.
  • Surgery must consist of mastectomy or conservative surgery with axillary lymph node dissection. Margins free of disease and ductal carcinoma in-situ (DCIS) are required. Lobular carcinoma is not considered a positive margin.
  • Node negative patients with tumour size > 2 cm.
  • Positive axillary lymph nodes defined as at least 1 out of 6 nodes with presence of disease. If sentinel node technique is used, sentinel node can be the only node affected. Patients belonging to the following classifications are eligible: pN1a, pN2a, pN3a.
  • Status of hormone receptors in primary tumour. Negative results must be available before the end of adjuvant chemotherapy.
  • Patients must not present evidence of metastatic disease.
  • Negative status of HER2 in primary tumour, known before randomization.
  • Adjuvant chemotherapy consisting of a minimum of 6 courses with anthracyclines and/or taxanes.
  • Age >= 18 and <= 70 years old.
  • Performance status (Karnofsky index) >= 80.
  • Laboratory results (within 14 days prior to randomization):
  • Hematology:

    • neutrophils >= 1.5 x 10e9/l;
    • platelets >= 100x 10e9/l;
    • hemoglobin >= 10 mg/dl
  • Hepatic function:

    • total bilirubin <= 1 UNL;
    • SGOT and SGPT <= 2.5 UNL;
    • alkaline phosphatase <= 2.5 UNL.
    • If values of SGOT and SGPT > 1.5 UNL are associated to alkaline phosphatase > 2.5 UNL, patient is not eligible.
