Active clinical trials for "Breast Neoplasms"

This research trial studies heavy metal exposure in predicting peripheral neuropathy in patients with stage I-III breast cancer undergoing chemotherapy. Studying samples of blood and urine in the laboratory for heavy metal exposure from patients receiving chemotherapy may help doctors find out whether side effects from chemotherapy are related to heavy metal exposure.

This pilot clinical trial studies comprehensive gene sequencing in guiding treatment recommendations in patients with metastatic or recurrent solid tumors. Studying samples of blood and tissue from patients with cancer in the laboratory may improve the ability to plan treatment.

This study is to investigate sex hormones levels of Chinese patients with invasive breast cancer.The aim is to analyze biochemical monitoring results of premenopausal and postmenopausal patients to facilitate determination of menopausal status and propose clinical application.

This research study is a pilot study designed to evaluate magnetic resonance imaging-guided therapy (MRT) as a possible treatment for breast cancer. In this pilot study, the investigators are studying if it is possible to use intra-operative MRI to guide surgery. The therapy takes place in the Advanced Multimodality Image Guided Operating (AMIGO) suite at Brigham and Women's Hospital. The purpose of this study is to investigate if it is possible to perform the breast conserving surgery with the help of intra-operative magnetic resonance imaging in the advanced multimodality image guided operating suite. It is hoped that intra operative MRI may improve the surgeon's ability to know the exact margins of tumor. Currently, approximately 40% of women need to come back to the operating room and have the margins of the cancer re-excised.

This study will correlate the resection margin status of the breast cancer tumour (WLE specimen), cavity shavings (if any) and breast cavity, and the metastatic status of axillary lymph nodes as determined by EnLight, LightPath, and histopathology. This is a pilot study to assess feasibility before proceeding to a pivotal study to evaluate the use of these imaging systems in clinical practice.

The purpose of this survey is to examine the safety and efficacy of long-term use (96 weeks) of leuprorelin acetate SR (slow release) 11.25 milligram (mg) for injection (Leuplin SR 11.25 mg for Injection) in premenopausal breast cancer patients in daily medical practice, as well as to examine factors that can influence the safety and efficacy of treatment with leuprorelin acetate SR 11.25 mg for injection (Leuplin SR 11.25 mg for Injection).

The goal of this research study is to learn about how dexmedetomidine (a standard of care sedative) affects your immune system (your defenses against cancer) by measuring your white blood cell levels before and after surgery.

The purpose of this non-interventional study is to collect data on the efficacy and safety of Nab-Paclitaxel in the routine application.

The purpose: To investigate the diagnostic accuracy of 18F-FLT PET for the suspicious lesions on mammograms and ultrasound.

Breast cancer represents the most frequent form of neoplasia in women worldwide, being responsible of 1.6% of annual deaths. Therefore, it is a major public health issue and research in this field should be a priority. Taxanes, such as paclitaxel and docetaxel, are extremely powerful antineoplastic drugs, which alone or in association to anthracyclines, increase survival and lower the recurrence rate of cancer, but their use is limited by cardiotoxicity. Cardiotoxicity can appear early or late after therapy, and may vary from subclinical myocardial dysfunction to irreversible heart failure. Currently, cardiac dysfunction induced by taxanes is diagnosed through classical echocardiographic parameters. However, these cannot detect subtle, early changes of cardiac structure and function. Consequently, description of new parameters, which could detect cardiac dysfunction in an early stage, becomes essential for detecting the group of patients at risk for irreversible heart failure. The objectives of the investigators project, in patients with breast cancer treated with taxanes, are to investigate their mechanisms which lead to cardiac dysfunction, to describe new parameters for the early diagnosis of cardiotoxicity, and to define predictive models for cardiotoxicity. Meanwhile, project will publish the results in prestigious journals, leading to an increase of the visibility of Romanian research internationally.
