Active clinical trials for "Breast Neoplasms"

This randomized, open-label, crossover study will evaluate participants' preference and healthcare professional (HCP) satisfaction with SC versus IV Herceptin administration in HER2-positive early breast cancer. Participants will be randomized to receive either SC Herceptin or IV Herceptin every 3 weeks for Cycles 1 to 4, followed by crossover to the other treatment administration for Cycles 5 to 8. For up to 10 additional cycles (for a total of 18 cycles), participants will receive IV or SC Herceptin every 3 weeks.

Background: - Some bacteria found in the large and small intestines help keep people healthy and aid digestion. They may also affect a person s risk of developing cancer. Researchers want to study the relationship between intestinal bacteria and breast cancer risk factors. They can do this by looking at stool and urine samples from postmenopausal women. Objectives: - To study intestinal bacteria and its relationship to urine-based markers of breast cancer risk in women. Eligibility: - Women between 55 and 69 years of age with a recent mammogram that showed no signs of cancer. Design: Participants will be screened with a medical history and basic health questionnaire. At home, participants will complete questionnaires about cancer risk factors and food consumption. Participants will also collect urine and stool samples. They will send the samples to the designated labs for study. No treatment will be provided as part of this protocol.

High sensitivity to targeted agents has been observed in patients whose tumor cells present a genetic/genomic deregulation of the target (Kit mutation, ERBB2 amplification, EGFR mutations) together with addiction to the given target. More recently, activation of "alternative pathways" (Kras mutation, PI3K mutations) have been reported as a common resistance mechanism to single agent tyrosine kinase inhibitors (trastuzumab, cetuximab). From these data has emerged the hypothesis that identification of the deregulated pathway through new molecular tools could allow to propose a more tailored targeted regimen. Based on these concepts, numbers of phase I/II trials enrich their populations in patients presenting specific molecular alterations. High throughput technologies (array CGH, sequencing, gene expression array) identify deregulated genes. In addition, these technologies determine whether such genomic alterations are single (expected efficacy of single agent) or multiple (rationale for combination). In a pilot study that included 135 patients, we recently performed a combination of array CGH and hot spot mutation array in order to drive patients into phase I/II clinical trials. This study led to the conclusions that high throughput technologies i. are feasible (80%) and robust, ii. identify "targetable" genomic alterations in around 40% of samples. In the present study, the investigators will perform high throughput technologies to drive 400 metastatic breast cancer patients into specific phase I/II trials.

This observational study, conducted by the Kenya Society for Hematology and Oncology, will develop a Breast Cancer and Care Registry (BRECC) for Kenya. Data on demographic, clinical and pathological characteristics, treatment and clinical outcome will be collected from newly diagnosed breast cancer patients. Breast cancer patients will be recruited into this registry cohort and followed up for a period of not less than five years.

The goal of this research is to further develop novel optical assay systems for intra operative assessment of tumor margins in partial mastectomy or mastectomy specimens.

RATIONALE: Dietary fats, fruits, vegetables, and fiber may affect the risk of breast cancer recurrence. PURPOSE: Randomized clinical trial to determine the effectiveness of a diet rich in vegetables, fruit, and fiber and low in fat in women who have been treated for stage I, stage II, or stage III breast cancer.

Current guidelines recommend endocrine treatment with aromatase inhibitors (AIs) in post-menopausal women with hormone receptor-positive breast cancer. Musculoskeletal symptoms are commonly reported with AI treatment,however, we do not have consistent methods to measure these symptoms prospectively. This gap in our knowledge inhibits the ability to test and develop treatments for AI-associated musculoskeletal symptoms. This pilot study will evaluate functional tests and standardized instruments for their ability to prospectively assess musculoskeletal symptoms in women being treated with AIs for breast cancer.

CYPTAM-BRUT 2 is a prospective, multicentric study including postmenopausal women receiving tamoxifen for metastatic, locally advanced (stage IIIB/C) or in the neoadjuvant setting for measurable estrogen-receptor positive breast cancers. The primary endpoint is the difference in efficacy of tamoxifen, defined as the objective response rate using RECIST criteria, between women with a normal versus low Tamoxifen Activity Score (TAS) after 3-6 months of tamoxifen use. The TAS score is based on the presence of genetic variations and drug interactions. Secondary endpoints are time to progression, clinical benefit, serum metabolite concentrations, endometrial changes and menopausal symptoms. Patients using tamoxifen in the neoadjuvant setting needs being operated between 4-6 months following the start of tamoxifen.

CYPTAM-BRUT 3 is a prospective, multicentric study in Belgium within the CYPTAM study of the Leiden University Medical Center (NTR1509) including postmenopausal women receiving tamoxifen for estrogen-receptor positive breast cancer in the adjuvant setting. The primary endpoint is the difference in uterine changes between women with a normal versus low TAS after 3 months of tamoxifen use. Secondary endpoints are serum metabolite concentrations, serum follicle-stimulating hormone level, serum sex hormone-binding globulin level and menopausal symptoms. These patients are registered in the Leiden protocol with time to breast cancer event as primary endpoint.

This is a single cohort observational safety study. All patients will be treated and monitored according to the local clinical practice. No additional procedures/patient visits in comparison with the usual clinical practice are planned for the study. Data will be collected from centre's medical records for up to 5 years or death.
