Filter by:The study is designed to confirm the current indication (below) of the CellSearch® Circulating Tumor Cell Kit in metastatic breast cancer (MBC) patients for use of the kit in China. The CellSearch® Circulating Tumor Cell Kit is intended for the enumeration of circulating tumor cells (CTC) of epithelial origin (CD45-, EpCAM+, and cytokeratins 8, 18+, and/or 19+) in whole blood. The presence of CTC in the peripheral blood, as detected by the CellSearch® Circulating Tumor Cell Kit, is associated with decreased progression free survival and decreased overall survival in patients treated for metastatic breast cancer. This test is to be used as an aid in the monitoring of patients with metastatic breast cancer. Serial testing for CTC should be used in conjunction with other clinical methods for monitoring metastatic breast cancer. Evaluation of CTC at any time during the course of disease allows assessment of patient prognosis and is predictive of progression free survival and overall survival.
The investigators hypothesize that Guaraná, a native plant from the Amazon, might improve chemotherapy-induced fatigue in breast cancer patients undergoing treatment. In order to assess this, the investigators randomized patients to either guaraná extract or to placebo, switching the assigned treatment mid-term through the cycles of Chemotherapy.
The aim of this study is to evaluate the success rate, insertion time and complication depending on the use of neuromuscular blocking agent when inserting the laryngeal mask airway (LMA).
The purpose of the study is to determine the efficacy and relapse rate of low dose, short duration treatment with tamoxifen in benign breast disease amenable to hormonal therapy with respect to etiology and estrogen receptor status and to realize its side-effects and cost of therapy. To do a comparative analysis of the results with evening primrose oil which is one of the first line management in benign breast disease.
RATIONALE: Collecting and storing samples of blood and tumor tissue from patients with cancer to test in the laboratory may help the study of cancer in the future. PURPOSE: This clinical trial is studying blood and tumor tissue samples in women with invasive breast cancer, ductal carcinoma in situ, lobular carcinoma in situ, or benign breast disease.
Prolactin is known to play an important role in breast development and differentiation. Thus proliferative breast diseases are good models to unravel PRl / PRLR function in proliferative processes. The aim of this project is to identify and to characterize new mutants of the prolactin receptor gene within cohorts of benign or malign breast diseases with low or high occurrence frequency in human populations
The purpose of this study is to compare conventional breast imaging and diagnostic work-up (2 dimensional imaging) to digital breast tomosynthesis (3 dimensional imaging) in the appearance of non-calcified breast masses. It is thought that non-calcified breast masses will be better visualized with the new 3D technology.
The purpose of this study is to determine the safety of three doses of topically applied danazol compared to placebo in subjects with pain associated with fibrocystic breast disease and to determine the appropriate clinical dose for future studies.
This is a study looking at advanced imaging such as PET/CT and MRI to see if they can provide a more accurate assessment of the patient with dense breasts or difficult to interpret mammograms. In addition, the ability to determine whether one or the other is more accurate or whether both together would be appropriate in this clinical situation, may be able to be measured. The MRI studies are very sensitive for detection of breast histopathology but less specific in differentiating between small low grade malignancies are more benign pathologies. Multifocal pathology can be challenging in determining site(s) for biopsy. PET scanning is specific in the measurement of metabolic glucose activity of various histopathologies and is accurate in differentiating aggressive from benign pathology in multifocal breast disease. A further drawback of PET is the lack of ability to observe lesions less than 3-4mm in diameter. In select cases the combination of MR and PET/CT is able to come to a more conclusive diagnosis - specifically with bilateral or multifocal breast disease.
The aim of our study is to investigate the potential role of the CYP2D6*4 polymorphism in breast cancer and furthermore to assess the role of oxidative stress, antioxidant capacity and ferretin in pathogenesis of breast cancer in different CYP2D6*4 genotypes
