Criteria

Inclusion Criteria

  • Patients with histologically documented breast cancer.
  • Patients with hormone receptor (ER and/or PgR) status of positive or unknown
  • Patients who have been amenorrheic for the preceding 12 months or more.
  • Patients who are 20 years or older and younger than 75 years.
  • Patients with a history of postoperative adjuvant therapy or a history of endocrine therapy with tamoxifen for the treatment of progression or recurrence of the lesion. The endocrine therapy, however, should not exceed one regimen.
  • Patients with progressing lesions.
  • Patients with sufficient organ function to evaluate the safety
  • Patients whose performance status (PS) is classified in 0~2.
  • Patients who have no residual effects from previous treatments

Exclusion Criteria

  • Patients with other concurrent or previous malignant disease (excluding uterine carcinoma in-situ).
  • Patients with hypercalcemia and uncontrollable cardiac disease (including a history of serious cardiac disease)
