Active clinical trials for "Breast Neoplasms"

RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer. It may also help doctors predict whether cancer will come back after treatment. PURPOSE: This research trial is studying genes that may predict local recurrence in samples from patients with breast cancer. treated on NSABP-B-28

Primary objective of the study is to evaluate the correlation between level of HER2-neu gene amplification evalued by dual-color Fluorescent in-situ hybridization (FISH) test and time to progression (TTP) in patients with HER2-positive advanced breast cancer treated with trastuzumab-containing regimens.

The NCIC CTG was conducting an international breast cancer prevention trial (MAP.3) examining the effects of a new therapy (exemestane) for breast cancer prevention in postmenopausal women at increased risk of developing this disease. Results showed that after a median follow up of 35 months, exemestane was superior to placebo in breast cancer prevention. Exemestane blocks estrogen production, which may be beneficial for preventing breast cancer, but may have negative effects on bone. As postmenopausal women are at risk for developing osteoporosis, determining whether exemestane causes bones to weaken is crucial for women considering it for long-term use. Dr. Cheung's team followed the bone health of 354 women in MAP.3 in detail over 2 years and found that volumetric bone mineral density (by high resolution peripheral quantitative computer tomography (HR-pQCT) at the radius and tibia as well as areal bone mineral density by dual energy x-ray absorptiometry (DXA) at the hip and spine decreased significantly with the use of exemestane. The long term effects of exemestane on bone will be examined up to 5 years of therapy and then 2 years post therapy to delineate the effects of exemestane on bone strength. This research will inform us on the safety of exemestane for breast cancer prevention.

To compare the overall QoL (Quality of Life) using Trial Outcome index (TOI) of FACT-B questionnaire for 3 years from baseline.

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

To determine the ability of the Cimmunology process to lead to in vitro antibody production, the ability of the ELISA assays to detect any of those antibodies, and to establish the relationship between the ELISA results and the clinical / pathological status of the patient. The statistical significance of the CAAb test results will be determined.

This study will examine the benefits of involving partner in a Screening, Brief Intervention and Referral to Treatment (SBIRT) program for tobacco and alcohol for women treated for breast cancer. Using a two-arm randomized trial (couple brief motivational intervention (CBMI) versus individual brief motivational intervention (IBMI) with repeated measures at 6 weeks, 3 and 6 months.

The primary purpose of our study is to evaluate whether gemcitabine as a single agent is superior to observation in improving progression-free survival (PFS) in patients with metastatic breast cancer (MBC) who achieved disease control with an initial six cycles of PG as their first-line treatment

The study purpose is to observe which neoadjuvant chemotherapy regimens is the better for invasive breast cancer. The neoadjuvant chemotherapy regimen is sustained anthracyclines plus taxanes or from anthracyclines plus taxanes to vinorelbine plus cisplatinum.

Human epidermalgrowth factor receptor-2(HER2) negative Luminal B subtype breast cancer patients are included. After 4 cycles of Capecitabine combined with Docetaxel(XT) protocol neoadjuvant chemotherapy ,those who reach partial response(PR) but not pathological complete response(pCR) are randomly divided into the group treated with XT protocol and the group with Capecitabine combined with Epirubicin and Cyclophosphamide(XEC) protocol ,then compare the disease free survival(DFS) and overall survival(OS) of two subgroup.
