Filter by:Breast radiation treatment is planned from a Computed Tomography (CT) scan. This study is designed to investigate a method to reduce the time between the planning of radiation treatment and its actual start by automating the intensity-modulated radiation therapy (IMRT) planning process. The investigators plan to examine data from another scan called Cone Beam Computed Tomography (CBCT). A CBCT scan provides similar information to a conventional CT scan, however the images for CBCT are acquired at the treatment unit (linear accelerator used for treatment). Using these x-ray pictures of patients, the study team consisting of a radiation oncologist, a medical physicist and a radiation therapist will create a custom treatment plan unique to each patient. By doing this, the investigators hope to reduce the amount of time spent waiting for treatment and the number of hospital visits for patients in the future.
Background: - Research suggests that breast cancers may arise from a population of stem cells in the normal mammary gland that produce clones of cancer cells. - Researchers are now trying to determine what events may initiate the formation of cancer cells. Objectives: - To look for and describe breast stem cells from normal breast tissue from women who do not have breast cancer. - To compare the breast stem cells between women at increased risk for breast cancer and women at average risk for breast cancer. - To show a relationship between the number and type of breast stem cells with the density (appearance) of the mammogram (breast x-ray). - To make cell cultures (grow cells under controlled conditions) from the breast stem cells. Eligibility: -Women 18 years of age and older who are at average or increased risk for breast cancer. Design: Participants complete a health history questionnaire, family history questionnaire and risk assessment questionnaire. - Participants have a mammogram and breast biopsy (surgical removal of a sample of breast tissue). - Women who can become pregnant have a urine pregnancy test....
25 patients, treated by brachytherapy in a phase II study "Mammosite" (from 2003 to 2005), will be asked to attend a clinical exam in order to evaluate the late cutaneous toxicity due to brachytherapy. During this consultation, a blood sample will be taken for analysis ( rate of CD8 T-Lymphocyte Apoptosis)
This study is being done to test the safety and effectiveness of two drugs, Anastrozole and Fulvestrant, used as combined therapy in the neo-adjuvant setting for hormone receptor positive invasive breast cancer.
The purpose of this study is to determine whether neo-adjuvant weekly paclitaxel with carboplatin is better than paclitaxel alone in efficiency and safety in early breast cancer, and to explore whether ultrasound and magnetic resonance imaging can predict the efficiency of neo-adjuvant chemotherapy.
This is a Phase II non-randomized, open, uncontrolled and bi-centric study of hormonal induction by exemestane (Aromasin) + tamoxifen to evaluate the effectiveness of exemestane (Aromasin) with tamoxifen on the rate of clinical response menopausal in patients with tumors of locally advanced breast. Hormone therapy will be administered at a dose of 25mg/day for exemestane and 20 mg / day for 4 months for tamoxifen.
RATIONALE: Studying the genes expressed in samples of tumor tissue from patients with cancer may help doctors identify biomarkers related to cancer. PURPOSE: This research study is looking at tumor tissue samples from patients who have undergone surgery for breast cancer.
RATIONALE: Green tea extract contains ingredients (catechins) that may lower the risk of breast cancer. PURPOSE: This phase II trial is studying how well green tea extract works in preventing breast cancer compared to a placebo in postmenopausal women with high breast density. The investigators have hypothesized that green tea consumption reduces breast cancer risk, and this effect is seen primarily in women who have the low-activity COMT genotype. The investigators will test this by evaluating the effects of green tea extract on breast cancer biomarkers including mammographic density, plasma insulin-like growth factor 1 (IGF-1), IGF binding protein 3 (IGFBP-3), estrone, estradiol, androstenedione, sex hormone binding globulin (SHBG), urinary estrogen metabolites and plasma F2-isoprostanes.
Though brain metastases are a risk in all patients with breast cancer, those with HER-2 overexpression are at significantly greater risk. One series estimated a 30% incidence of brain metastases in this population, while another study found an incidence of approximately 40%. Traditional systemic therapies do not cross the blood brain barrier to any significant degree or at all, but radiation treatment can be effective in the treatment of intracranial metastases.
About 1/3 of newly diagnosed breast cancer patients are mothers of children who still live at home. They face additional challenges and stress, their children are also affected by the mother's illness. The oncological rehabilitation programme "getting better together" focuses on these special family needs. This waiting-control-group study examines the effectiveness of the intervention by accompanying the patients and their children over the course of a year and assessing their quality of life and psychological health.
