Active clinical trials for "Breast Neoplasms"

The purpose of this study is to determine how well changes can be determined in malignant masses from ultrasound scans.

Glutamine, a non essential branched chain amino acid, is most important non toxic nitrogen carrier in body. It participates in variety of physiological functions. It is a major fuel source of enterocytes and is a substrate for gluconeogenesis in kidney, lymphocytes, and monocytes. It is also a nutrient in muscle protein metabolism in response to infection, inflammation and muscle trauma. The significance of glutamine to metabolic homeostasis becomes evident during periods of stress, when it becomes a conditionally essential amino acid. Role of glutamine as protective agent in hepato-biliary dysfunction, in maintaining mucosal integrity of the Gastrointestinal tract following its administration in patient with major bowel surgery as a supplement and part of TPN in critically ill patients and in patients of septicemia, is well established. However the role of glutamine supplementation in reducing or preventing chemotherapeutic agents induced toxicity in cancer patients is controversial.

This study will evaluate the activity of single agent trastuzumab or lapatinib in patients not previously treated for HER-2 positive (FISH positive) metastatic breast cancer. A companion biological study will assess factors correlated with sensitivity or resistance to either one of the compounds

The purpose of this study is to determine whether raloxifene compared with placebo lowers the risk of coronary events and reduces the risk of invasive breast cancer in postmenopausal women at risk for major coronary events.

The overall goal of this study is to determine how FDG-PET can be incorporated into the assessment of the axilla in the staging and treatment of women with early stage breast cancer. A multicentre, prospective, diagnostic accuracy study will be conducted evaluating the ability of positronic emission tomography using fluorodeoxyglucose (FDG-PET) to detect the presence or absence of axillary lymph node metastases in newly diagnosed breast cancer patients with no clinical evidence of spread of disease beyond the breast.

The primary goal of this study is to compare, within a clinical screening setting, the performance of stereoscopic digital mammography with standard (non-stereo) digital mammography in the detection of abnormalities in the breast, including early breast cancer.

We aim to compare the sensitivity of mammography to the sensitivity of Molecular Breast Imaging (a new gamma-camera based breast imaging technology) in women with dense breast tissue who are at increased risk for breast cancer.

The purpose of this study is to determine the sensitivity of Molecular Breast Imaging (MBI) relative to MRI of the breast in patients undergoing MRI for a clinical concern, or abnormal diagnostic mammogram and/or ultrasound study.

Tomotherapy is a new radiation therapy system that uses an integrated CT scanner during delivery of radiation treatment to improve the accuracy of the treatment. Furthermore the irradiation is delivered helicoidally allowing highly conformal shaping of dose distribution. However the magnitude of the clinical advantage of using the system in breast cancer is unknown. The purpose of the present study is to investigate whether or not the Tomotherapy can substantially reduce pulmonary and cardiac toxicities, as compared with conventional radiotherapy.

The purpose of this study is to determine whether family physician 'routine follow-up care' of women with breast cancer in remission is an acceptable alternative to the existing system of specialist follow-up. Primary outcome measure are event rates of oncological catastrophes and quality of life.
