Active clinical trials for "Breast Neoplasms"

RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur and identify biomarkers related to cancer. PURPOSE: This research study is looking at blood glycan biomarkers in women with stage IV breast cancer.

HSP90 inhibition is a potentially new targeted drug modality in the treatment of HER2 positive, trastuzumab refractory breast cancer. Little is known about the pharmacodynamics of HSP90 inhibitors in vivo, but non-invasive PET/CT imaging in a xenograft mouse model could visualize and quantify HER2 reduction after AUY922 treatment by 89Zr-trastuzumab PET imaging. Two doses of 50 mg/kg AUY922 resulted in a decrease in HER2 expression of approximately 50%, quantified 6 days after the last administration of AUY922. Visualizing HER2 expression in breast cancer patients before and early following HSP90 inhibition by means of 89Zr-trastuzumab PET, is likely to provide insight in the early in vivo effect of HSP90 inhibition and could potentially support patient tailored therapy.

RATIONALE: Diagnostic procedures, such as laser spectroscopy, may help find and diagnose breast cancer. PURPOSE: This phase I trial is studying laser spectroscopy to see how well it works in diagnosing breast cancer in women with breast lesions.

This study will examine the relationship of a protein called pAKT to survival of breast cancer patients with one or more positive axillary lymph nodes. Akt plays a role in cell survival, tumor formation, and the development of drug resistance. The study will use tumor tissue obtained from 2,000 patients enrolled in a National Surgical Adjuvant Breast and Bowel Project study that is evaluating whether adding the drug paclitaxel (Taxol (Registered Trademark)) to a treatment regimen of doxorubicin (Adriamycin (Registered Trademark)) and cyclophosphamide (Cytoxan (Registered Trademark)) improves disease-free survival and overall survival in patients with node-positive breast cancer. The current study will measure levels of pAkt in the tissues and correlate the results with clinical outcome to see if pAkt levels are associated with improved patient survival. ...

This observational study will characterize retrospectively patients with HER2-positive metastatic or locally advanced breast cancer who had received treatment with Herceptin (trastuzumab) in 1st line and who were without progression for at least three years. Patients will be followed prospectively for one year.

The purpose of this study is to learn about the effects of stress on hormones, the relationship between these hormones and cancer progression.

RATIONALE: Studying how older women make treatment decisions and how these decisions affect the outcome of treatment may help doctors plan more effective treatments and improve patient quality of life. PURPOSE: This clinical trial is studying how a patient's treatment preferences and decisions about chemotherapy affect the outcome of treatment in older women with newly diagnosed breast cancer.

The efficacy of peer counseling for weight loss maintenance is being tested in obese and overweight African American breast cancer survivors.

This is a prospective observational cohort study designed to describe effectiveness and safety (treatment outcomes and clinically significant cardiac adverse events, respectively) in patients with HER2-positive metastatic breast cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: This clinical trial is studying the effect of chemotherapy on heart function in treating women who have breast cancer with negative axillary lymph nodes and who are undergoing treatment on the SWOG-8897 clinical trial.
