Brief summary: It is a phase III trial to explore the efficacy and safety of vinorelbine plus capecitabine (NX) and docetaxel plus capecitabine (TX) as first line treatment followed by capecitabine alone till Progressive Disease(PD). We plan to enroll 200 pts for limited budget and the non-inferior trend of the two curves is anticipated.

Detailed description: We designed the randomized non-inferiority study. Main Inclusion\& exclusion Criteria include: 1) Histologically or cytologically confirmed breast cancer with unresectable locally advanced and/or metastatic disease; 2) Untreated patients with unresectable locally advanced and/or metastatic disease; 3) with at least 1 lesion measurable by radiological method(RECIST criteria); 4) Karnofsky Performance Status(KPS)≥70; 5) normal Adequate hepatic, renal, and bone marrow function; 6) Life expectancy of at least 12 weeks; 7) No previous chemotherapy for metastatic breast cancer. Primary endpoint is Progression free survival(PFS), second endpoint are safety profiles (National Cancer Institute-Common Toxicity Criteria 3.0, NCI-CTC 3.0), overall survival and response rate. During Primary study treatment, Arm A: Capecitabine: 1,000 mg/m2 per ora(PO) twice daily (day 1-14), Vinorelbine 25 mg/m2 intravenous(IV) over 3 hours on day 1 and 8, every 3 weeks, 21 days as one cycle and 6-8 cycles are required; Arm B: Capecitabine: 1,000 mg/m2 PO twice daily (day 1-14), Docetaxel 75 mg/m2 IV over 3 hours on day 1, every 3 weeks, 21 days as one cycle and 6-8 cycles are required. Patients who are responding (complete or partial), or whose disease is stable followed by Capecitabine: 1,000 mg/m2 PO twice daily (day 1-14) 21 days as one cycle until progression or unacceptable toxicity

Eligibility criteria: Inclusion Criteria:

* Written and signed informed consent prior to beginning specific protocol procedures.
* Pathologically confirmed breast cancer and documented metastatic or locally advanced disease.

Measurable disease (RECIST criteria) - with at least 1 lesion measurable by radiological method

* KPS\>=70
* Adjuvant and/or Neoadjuvant chemotherapy, including an anthracycline was permitted
* Hormone therapy for early-stage or metastatic breast cancer was permitted if hormonal receptor positive.
* Treatment with Herceptin for early-stage or metastatic breast cancer is permitted if HER2 positive
* Patients had to have concluded prior radiation therapy at least 14 days before enrollment.
* Laboratory requirements:

  * Hematology Absolute neutrophil count\>=1,500 /μl; Platelets\>=100,000 /μl; Hemoglobin\>=10 g/dl
  * Liver function Total bilirubin\<=2 times ULN ASAT (SGOT) and ALAT (SGPT)\<=2.5 times UNL without liver metastasis or \<=5.0 times if liver metastasis Glucose\<=200 mg/dL
  * Renal function Serum creatinine\<=140 mol/l
* Life expectancy of at least 12 weeks
* Patients must be accessible for treatment and follow-up.
* Patients should have recovered from the acute reversible effects of prior treatment. This generally means at least 3 weeks should have elapsed since prior chemotherapy, adjuvant or Neoadjuvant treatment. and at least 4 weeks since prior (radical) radiotherapy or major surgery

Exclusion Criteria:

* Women who are pregnant or breast feeding
* History of brain and/or leptomeningeal metastases
* Previous chemotherapy for metastatic breast cancer
* Past or current history of malignant neoplasm other than breast carcinoma, except for curatively treated non melanoma skin cancer, in situ carcinoma of the cervix or other cancer curatively treated and with no evidence of disease for at least 5 years
* Pre-existing neuropathy grade 1 according to the NCIC-CTC 3.0
* Psychiatric disorders or other conditions which would prevent pt. compliance
* Other serious illness or medical condition:

  * Congestive heart failure, or unstable angina pectoris, previous history of myocardial infarction within 6 month prior to study entry, uncontrolled hypertension as determined by the Investigator or high risk uncontrolled, arrhythmia.
  * History of significant neurological or psychiatric disorders including psychotic disorders, dementia of seizures that would prohibit the understanding and giving of informed consent.
  * Active uncontrolled infection.
  * Unstable peptic ulcer, unstable diabetes mellitus or other contraindication for the use of Corticosteroids.
* Inability to take and/or absorb oral medicine
* Prior treatment with an docetaxel and/or capecitabine and/or vinorbine
* Concurrent treatment with other experimental drugs, or participation in another clinical trial with any investigational drug within 30 days prior to study entry
