About this study
Official title: Gene Expression Signature and Immunohistochemical Markers Associated With Response to Neoadjuvant Chemotherapy in Locally Advanced Breast Cancer
The purpose of this study is to analyze gene expression signature and immunohistochemical markers associated with clinical and pathological response to neoadjuvant chemotherapy in locally advanced breast cancer.
Read the detailed description
Locally advanced breast cancer is a common condition in development countries. Neoadjuvant chemotherapy gives the opportunity to identify genetic signatures associated with objective clinical and pathological complete responses.
Patients will receive doxorubicin/cyclophosphamide with paclitaxel. Tumor samples collected before and after chemotherapy will be analyzed.
- Conditions
- Breast Cancer
- Being tested
- doxorubicin, cyclophosphamide, paclitaxel, Surgery
- Keywords
- neoadjuvant chemotherapy, advanced breast cancer, microarray, correlation analysis, oncoplastic surgery
- Medical subject headings
- Breast Neoplasms

Questions about this trial
What is this clinical trial studying?
An observational study of Breast Cancer, run by Barretos Cancer Hospital at 1 site in Brazil.
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 5 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 5 Aug 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 Brazil. 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?
Results are not available in the source record.
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?
Clinical objective and pathological responses to chemotherapy (time frame: 8 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00820690, which also lists 21 linked publications.
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 5 Aug 2015.
