About this study
Official title: A PHASE II STUDY OF THE CLINICAL AND BIOLOGIC EFFECTS OF DOCETAXEL (TAXOTERE) IN PATIENTS WITH LOCALLY ADVANCED BREAST CANCER
The purposes of this study are to better understand how Taxotere causes tumors to become smaller and to find out how effective Taxotere is in treating the type of breast cancer that you have.
Read the detailed description
Systemic chemotherapy for operable breast cancer significantly decreases the risk of relapse and death. However, it is not possible to identify those patients at the outset who are likely to respond to adjuvant treatment and which type of treatment should be used. Adjuvant treatment given before surgery (neoadjuvant therapy) has a number of theoretical advantages in breast cancer, including a reduction in the requirement for mastectomy. Access to the primary tumor during early treatment allows for in vivo testing for change in molecular markers by repeat biopsies that may occur with successful treatment. Established prognostic factors like tumor size and nodal involvement are important indicators for breast cancer relapse and survival but have not been shown to be predictive of sensitivity to treatment. Estrogen receptor (ER) and progesterone receptor (PgR) expression predict for response to tamoxifen and endocrine treatment. However, predictive markers for chemotherapy are not established. Overexpression of c-erbB-2 has been associated with decreased response to CMF chemotherapy (cyclophosphamide, methotrexate, and 5-fluorouracil) in most studies. Accumulation of aberrant protein expressed by the mutated tumor suppressor gene p53 product may be associated with relative resistance to cytotoxic therapy. Tissue growth kinetics are determined by the balance between programmed cell death (apoptosis) and cell proliferation, and any alteration between the two may be regarded as a key element for the uncontrolled growth of malignant tumors. In vitro experiments suggest that many anti-cancer agents achieve their effect by inducing apoptosis. Mechanisms that suppress this process may, therefore, be important in the development of intrinsic and acquired chemotherapy resistance. A clinical study has reported an increase in labeled apoptotic leukemic cells during treatment. In breast cancer biopsy specimens, chemotherapy was found to induce apoptosis within the first 24 hours of treatment.
Measurement of biological molecular markers before and after exposure may, therefore, allow for early prediction of the likelihood of response to systemic therapy. Preoperative chemotherapy has been shown to result in changes in biomarkers, and these changes, when correlated with tumor response, may be early predictors of clinical outcome.
New treatment strategies are needed to improve the clinical outcome in breast cancer patients at high risk of recurrence. Even with the best present combination chemotherapy, radiotherapy, and surgery, disease recurrence and death is at least 60% in this population. Thus, new strategies are needed to improve survival. Recent advances that may improve clinical outcome include the use of taxoids (paclitaxel and docetaxel), a new class of cytotoxic agents, with reported higher response rates than standard anthracycline-based chemotherapy.

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.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
efficacy of neoadjuvantTaxotere in patients with locally advanced breast cancer. Histological complete response rate. 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 17 Nov 2011.
