Primary Outcome Measures:
  • Chemotherapy response [ Time Frame: four-months ] [ Designated as safety issue: Yes ]
    Response to chemotherapy is assessed using Response Evaluation Criteria in Solid Tumor Group (RECIST) guidelines


Secondary Outcome Measures:
  • Time to disease progression [ Time Frame: six months ] [ Designated as safety issue: Yes ]
    Time to disease progression is measured from the date therapy is initiated to the date of documented disease progression.

  • Overall survival [ Time Frame: one year ] [ Designated as safety issue: Yes ]
    Overall survival is measured from the date therapy is initiated to the date of death or final follow-up.

  • clinical benefit response [ Time Frame: six months to one year ] [ Designated as safety issue: Yes ]
    clinical benefit response include CR,PR,SD


Biospecimen Retention:   Samples Without DNA

the tissue will be obtained by core niddle biopsy.

Estimated Study Completion Date: July 2013
Estimated Primary Completion Date: July 2012 (Final data collection date for primary outcome measure)
Detailed Description:
  1. Metastatic breast cancer tissue is obtained from core needle biopsies pretreatment and is flash frozen and stored at -70℃ until processing.
  2. After patients received docetaxel combination thiotepa for two cycles, response is assessed using Response Evaluation Criteria in Solid Tumor Group (RECIST) guidelines. Degree of response is used to divide the cancers into two groups—sensitive and resistant tumours.
  3. The gene expression in metastatic breast cancer tissue sample is detected by microarray to screen gene markers that are differently expressed between groups
  4. Statistical analysis is performed using unsupervised hierarchical cluster.
