Filter by:This study will look at effects the combination of palbociclib and letrozole may have on estrogen receptor (ER)-positive/human epidermal growth factor receptor 2 (HER2)-negative breast cancer tumors which have not yet been treated. Letrozole is a type of endocrine therapy called an aromatase inhibitor (AI) and is standard treatment for post-menopausal women with ER-positive/HER2-negative breast cancer.
Breast cancer is the most common cancer and the second leading cause of cancer related death in American women. Regular screening, early diagnosis, and timely treatment initiation have been shown to reduce breast cancer morbidity and mortality. However, disparities continue to exist across the breast cancer continuum for underserved women, particularly minority women. The reduction of disparities in breast cancer outcomes is a major goal of Healthy People 2020 and the National Cancer Institute. However, the preventable burden of late stage breast cancer will continue until the investigators close the gap between what is known about prevention and what is implemented in the community. Although many sources of information exist about theory and [theory-] and evidence-based interventions (EBIs) to promote mammography screening, their adoption and use in the community has been limited and haphazard at best.
Radiation therapy may kill any tumor cells remaining after surgery. This randomized phase III trial is studying the effect of an extra dose of radiation therapy (Boost dose) after breast conserving surgery and 50 Gy adjuvant external beam radiotherapy to see how well it works compared to no further therapy in treating women with early breast cancer that has been surgically removed.
Many patients with ER-positive or PR-positive breast cancer are treated with endocrine therapy. Although most ER/PR-positive tumors initially respond to hormonal therapy, patients often experience disease progression. Everolimus, in combination with exemestane, has shown activity in endocrine-resistant disease. This study will evaluate the efficacy of Everolimus+ anti-estrogen therapy in patients with ER-positive metastatic breast cancer who have progressed after receiving anti-estrogen therapy.
To compare the kinetics and efficacy of two functionally different diagnostic agents, Lymphoseek (CD206 receptor targeted) and 99mTc-Sulfur Colloid (SC) (Sulfur Colloid non-specific mapping agent) in intraoperative lymphatic mapping (ILM) and Sentinel Lymph Node Biopsy (SLNB).
Some breast cancer cells make a protein called Human Epidermal Growth factor receptor 2 (HER2). Patients with HER2 positive (HER2+) breast cancer receive medicine that attacks HER2, which helps these patients live longer. Some HER2 negative (HER2-) breast cancer patients also benefit from medicines that attack HER2, but we do not know why or which patients will benefit. This study uses a new imaging method, HER2-targeted PET/CT, to identify patients that may benefit from medicines that attack HER2. This is experimental.
The purpose of this study is to confirm the findings of an early study and expand our knowledge of treating Malignant Carcinoma in the Breast Tissue Using an ATP (Adenosine-5'-Triphosphate) Inhibitor.
This non-interventional prospective study will assess the safety of Herceptin SC (subcutaneous administration) as used in routine clinical practice. Patients with HER2-positive early breast cancer, naive and non-naive of HER2+ treatment who are to be treated in the neoadjuvant and adjuvant setting and scheduled to initiate a treatment with Herceptin SC in routine clinical practice use are eligible to participate. The total study duration is anticipated to be 38 months.
This study is designed as a phase 1 dose escalation study followed by a randomised phase II study. The study will be performed in three different centres: Addenbrooke & Cambridge university (Cambridge, UK), Netherlands Cancer Institute Amsterdam), and Vall d'Hebron Hospital (Barcelona, Spain). Three to six patients will be followed for one completed cycle of therapy (28 days) and subsequent enrolment of new cohorts will be based on the safety assessment in that first cycle and the documentation of dose limiting toxicities. To determine the safety and efficacy of tamoxifen in combination with the isoform selective Pi3K inhibitor GDC-0032 compared with tamoxifen alone.
The role among metabolic syndrome and breast cancer risk is not well understood and must be further explored. The objective of this study is to evaluate the association between metabolic syndrome and breast cancer in Southern Brazil. In this case-control study, breast cancer patients and controls without malignant disease, matched for age (±5 years) and menopausal status, were interviewed and asked to make a glucose, HDL-cholesterol and triglycerides test. Waist circumference and blood pressure were measured using standardized procedures. Metabolic Syndrome was considered by NCEP ATP III (2001) and IDF (2006) definitions. Cases and controls were compared in relation to the presence of diagnosed MetS (yes/no), number of metabolic abnormalities identified (1 to 5) for each definition, and according to each metabolic abnormality cutoff point.
