About this study

The investigators want to develop a gene expression profile the for prediction the chemotherapeutic response of patients with metastatic breast cancer.

Read the 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Chemotherapy response

    Response to chemotherapy is assessed using Response Evaluation Criteria in Solid Tumor Group (RECIST) guidelines

    Measured: four-months

Secondary outcomes (3)
  1. Time to disease progression

    Time to disease progression is measured from the date therapy is initiated to the date of documented disease progression.

    Measured: six months

  2. Overall survival

    Overall survival is measured from the date therapy is initiated to the date of death or final follow-up.

    Measured: one year

  3. clinical benefit response

    clinical benefit response include CR,PR,SD

    Measured: six months to one year

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Neoplasms and Neoplasm Metastasis, run by Peking University Cancer Hospital & Institute at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 23 Jul 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Chemotherapy response (time frame: four-months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jul 2015.
