Active clinical trials for "Breast Neoplasms"

Diet has been found to influence hormone production and metabolism which in turn could affect the incidence of hormone related cancers. Consumption of soy-containing foods, known to be rich in phytoestrogens, is thought to be one of the chemoprotective factors against breast cancer in Asian populations. Phytoestrogens have a wide range of metabolic effects and may have a role in effecting breast cancer risk. Although there is mounting evidence of the positive influence of phytoestrogens on breast cancer risk, very little research has been carried out in humans as to the effects of phytoestrogens on breast cancer recurrence and survival. The DietCompLyf study aims to explore this effect by carrying out an observational study in 3,000 breast cancer women in the UK. The effects of diet, lifestyle practices and use of complementary treatments will also be investigated. Participants are recruited 9-15 months post-diagnosis and followed up for 5 years. Questionnaires as well as blood and urine samples are collected annually.

Radiation induced accelerated atherosclerosis is a well known entity that occurs in different regions, according to the therapy delivered.It is usually begins to be clinically evident several years after the radiation incident, as there is sufficient functional reserve to these vessels.Our proposal is aimed to better characterize this side effect. For that purpose, we have chosen to study women who received radiation to the breast, in which part of the carotid in the irradiated side was in the high energy radiation field. We will use Intima Media Thickening ultrasound to study the pattern of atherosclerosis plaque formation in radiated carotid arteries as compared to non-irradiated carotid arteries in women who are receiving radiation therapy for breast cancer.

The purpose of this study is to investigate the relationship between the side effects(especially arthralgia and arthritis) which appear in the patients who are prescribed aromatase inhibitor(AI) and the CYP19 genetic polymorphisms.

RATIONALE: Studying the genes expressed in samples of 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 blood samples from high-risk postmenopausal women who received treatment on breast cancer prevention clinical trials NSABP-P-1 or NSABP-P-2.

RATIONALE: Studying samples of tumor tissue 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 tissue samples from patients with breast cancer.

RATIONALE: Studying samples of tissue 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 trial studies biomarkers as a predictor of response to trastuzumab in samples from patients with breast cancer previously treated in the NSABP-B-31 trial.

Breast cancer triples negatives (TN; 15 % of the cases) are characterized by a high histoprognostic grade, a strong proliferation, a strong metastatic power, and a worse prognosis than the other forms of breast cancer. It is however a heterogenous group for histological and molecular level, but also for evolution. Most of the TN is part of the basal breast cancer subcategory. Until now, the medical treatment is based on chemotherapy. Breast cancers by constitutional mutation of BRCA1 / BRCA2 (5 % of breast cancers) are mostly of basal type and their prognostic seems better that what could be expected from high grade tumours and without hormonal receptors. They would be much more frequent in the TN group. However, at this day, no prospective study was led to estimate this incidence, or to study the intervention of other genes of predisposition, as well to analyse the links between this phenotype and their consequences at the germinal or somatic level, in terms of associated molecular changes and prognosis. The purpose of this study is, on a prospective study, to lead a joined analysis at the germinal level, in search of mutations of the main genes of breast cancer predisposition (BRCA1/2, PALB2, PTEN, PALB2), and at the tumour level (tissue micro-array and transcriptome), by correlating these results to the main clinical parameters. The 5 years relapse-free survival will also be estimated.

PRIMARY STUDY OBJECTIVES: To evaluate dosimetric outcomes in tumor bed boost irradiation in patients undergoing breast conservative surgery using three different surgical techniques SECONDARY OBJECTIVES- Evaluation of cosmesis in patients prior to radiotherapy, at the time of completion of radiotherapy and 6 months post completion of radiotherapy STUDY DESIGN: Three arm, Prospective Observational Trial TREATMENT REGIMEN: Group A- Patients who underwent open cavity Breast Conservative surgery(BCS) Group B- Patients who underwent closed cavity BCS Group C- Patients who underwent oncoplasty All patients will first receive external beam Radiotherapy to the whole breast to a dose of 40 Grays /15#/3 weeks. The patients will then be planned for boost radiation to the tumor bed to a dose of 12.5 Grays/5#. RECRUITMENT TARGET: 20 Patients The sample size has not been calculated as this is a pilot study. Twenty patients will be accrued for the purpose of this study PRIMARY ENDPOINT Dosimetric Measurement Seroma cavity volume (ccs). PTV volume (ccs). Ratio between the PTV volumes to the whole breast volume Radiation Conformity Index (RCI) Dose Homogeneity Index (DHI) Ratio of dose received by 95% of PTV volume to the dose received by 5% of PTV volume Dose received by several normal structures; normal ipsilateral breast tissue, contralateral breast, ipsilateral lung, contralateral lung, and heart Cosmesis Measurement prior to starting radiotherapy, at the time of conclusion of radiotherapy 6 months post completion of radiotherapy

This 2-year trial is intended to be used to study breast cancer patients through forward-looking generation design through collaboration between Chinese and Western medical teams. The whole study consists of 2 stages, stage I comprises a cross-sectional study-baseline and stage II is a cohort for outcome evaluation and follow-up study across a 3-year period. To provide an empirical basis for combined TCM treatment in the Breast Cancer Research Team and to publish that as a reference for future TCM and Western medicine in integrative cancer treatment.

This is a pilot study to examine PVSRIPO bioactivity in tumor tissue after intratumoral administration of PVSRIPO in women with invasive breast cancer.
