入选标准

  • Patients with locally advanced/metastatic breast cancer who have progressed on the non-steroidal aromatase inhibitors (Arimidex™ or letrozole [Femara™]):
  • 1. Female postmenopausal patients defined as:
  • 1.1. Aged 60 years or over
  • 1.2. Aged 45 to 59 with intact uterus and amenorrhoeic for at least 12 months
  • 1.3. Any age having had a bilateral oophorectomy
  • 2. Histologically or cytologically confirmed adenocarcinoma of the breast
  • 3. Patients with original ER positive and/or progesterone (PgR) positive breast cancer which has relapsed or progressed during endocrine therapy with a single-agent non-steroidal aromatase inhibitor (NSAI) given either:
  • 3.1. As adjuvant treatment where the patient received at least 12 months therapy, or
  • 3.2. As first-line therapy for metastatic disease. Patients treated with an NSAI as first-line therapy must have had either an objective response (complete response [CR]/partial response [PR]), or stabilisation of disease for at least six months.
  • 4. Measurable/evaluable sites of metastatic disease (response evaluation criteria in solid tumours [RECIST])
  • 5. World Health Organisation (WHO) performance status zero, one or two
  • 6. Prior therapy permissible:
  • 6.1. Tamoxifen given in the adjuvant or neo-adjuvant setting only
  • 6.2. Prior chemotherapy in the adjuvant or neo-adjuvant setting
  • 6.3. Prior chemotherapy as first-line treatment for metastatic breast cancer followed by NSAI alone for at least six months
  • 6.4. Patients with bone-only metastases are eligible provided they have evaluable site of bone metastases that can be followed by skeletal survey or magnetic resonance imaging (MRI)/computed tomography (CT) scanning
  • 6.5. Patients already established on bisphosphonate therapy for at least six months are eligible for the trial and may continue on bisphosphonates
  • 7. Written informed consent and available for prolonged follow-up
  • 8. Adequate haematological function defined by haemoglobin more than or equal to 10 g/dl, neutrophil count more than or equal to 1.5 x 10^9/l and platelets more than or equal to 100 x 10^9/l
  • 9. Adequate hepatic function defined by aspartate aminotransferase (AST) and alanine aminotransferase (ALT) less than or equal to 2.5 x upper limit of normal. Alkaline phosphatase less than or equal to 5 x upper limit of normal, unless bone metastases in the absence of liver disease. Renal function adequate defined by creatinine less than 175 mmol/l.
  • 10. Life expectancy of more than three months and suitable for further endocrine therapy

排除标准

  • 1. Patients whose primary breast cancer was classified as:
  • 1.1. ER negative and PgR natural killer (NK)
  • 1.2. ER negative/PgR negative
  • 1.3. ER NK
  • 2. Rapidly progressive visceral disease (i.e., lymphangitis carcinomatosa, diffuse hepatic involvement)
  • 3. Bone-only metastases where lesions are not evaluable (i.e., patients with the same scan but no lytic disease on skeletal survey or MRI/CT)
  • 4. Patients with malignancies (other than breast cancer) within the last five years, except for adequately treated in situ carcinoma of the cervix or basal cell/squamous cell carcinoma of the skin
  • 5. Systemic corticosteroids for more than 15 days within the last four weeks
  • 6. Investigational drugs given within the previous four weeks
  • 7. Patients with thrombocytopaenia (platelets less than 100 x 10^9/l ) or on anti-coagulant therapy (contra-indicated due to risk of bleeding with intramuscular injection of Faslodex™)
