Active clinical trials for "Breast Neoplasms"

In 50 breast cancer patients, heavily pretreated with anti-hormonal therapy, the investigators will evaluate the use of 16-alpha[18-fluoro]-17beta-estradiol positron emission tomography (FES-PET)as predictive biomarker for response to estrogen therapy.

The purpose of this study is to study if a patients follows an exercise program specifically designed for them during the time of their treatment after surgery. Their ability to follow the program and its influence on their weight maintenance and early post-operative lymphedema rates will also be studied. Lymphedema is a condition in which excess fluid collects in tissue and causes swelling of the arm(s).

This study, conducted by the NCI and the George Washington University Medical Center (GWUMC), will examine breast tissue from patients with inflammatory breast cancer (IBC) for tumor markers and factors associated with angiogenesis. Angiogenesis is the formation of new blood vessels that is essential for tumor growth and spread. IBC is an extremely rare, aggressive form of breast cancer that disproportionately affects young women. The risk factors for IBC, its cause, and how it develops are unknown, but the disease appears to involve a high degree of angiogenesis. Tissue specimens for this study will be obtained from GWUMC's Inflammatory Breast Cancer Registry and Biospecimen Repository. The registry was established to develop a national registry of patients with IBC that includes standardized clinical, epidemiological, and pathological information, along with disease recurrence and survival data. For this study, tissue specimens from the repository will be tested for biological markers and angiogenesis parameters to help in the classification of the tumors. Biological markers (such as estrogen receptor, progesterone receptor, the p53 gene, and others) and angiogenesis parameters (such as various proteins involved in vessel formation) will be examined to determine their prevalence in tissue specimens and their relationship to patient survival. When possible, the findings will be compared with non-IBC tissue samples.

Aim of the study is to assess the impact on response to Herceptin-based therapy in patients with advanced breast cancer. Tumor specimens from primary breast cancer will be analized for several biological factors potentially involved in Herceptin sensitivity. Tests that will be performed include: FISH analyses of EGFR, HER-2, HER-3, C-MYC, PTEN, MET, IGFR-1. Immunofluorecence of P95HER2. Mutation analyses of EGFR, HER-2, MET, C-MYC, PTEN, KRAS, PIK3CA, IGFR-1. Immunohistochemistry of the same biomarkers.

This is an open label, non-interventional quality of life analysis for Arimidex treated postmenopausal patients in early breast cancer by investigator's questionnaire

The goal of this epidemiologic research study is to find out if various risk factors and certain markers (substances that help identify the presence of cancer) that help predict increased occurrence and prognosis (outcome of disease) of breast cancer differ among Mexican, Mexican-American, and African-American women.

The purpose of this study is to identify the combined impact on bone loss as well as the incidence of bone fractures in women with estrogen receptor (ER)-positive, early breast cancer treated with an aromatase inhibitor (AI) either as first line therapy or as maintenance therapy after initial treatment with chemotherapy, in real life clinical settings in Greece.

Cancer Survivor Registry: The Breast Cancer M.A. P. (Mind Affects the Physical M.A.P.) Project to identify and help us understand the emotional and social needs of breast cancer survivors.

This is a retrospective medical record abstraction study. It is a review and evaluation of up to 300 metastatic breast cancer patients treated with Abraxane or other taxanes such as paclitaxel and docetaxel to determine the overall cost of care for Abraxane compared to other taxanes in the first-line metastatic cancer setting and the cost of care for Abraxane compared to other taxanes when broken down by individual components of cost. In addition, the investigators will review the following patient outcomes: response rate, duration of therapy, toxicity, and survival.

The primary objective of this study is to acquire digital mammography images produced by the Xpress Digital Mammography System in order to develop Computer Aided Detection software and systems.
