Active clinical trials for "Breast Neoplasms"

The goal of this study is to evaluate the Salah Azaïz Cancer Institute male breast cancer patients population over a period of 14 years. Goal of the retrospective part: to gather clinicopathologic data and follow-up outcomes of male breast cancer patients diagnosed and/or treated at Salah Azaïz Cancer Institute from 2004 to 2013. Goal of the prospective part: to create a registry of male patients with breast cancer for a period of 48 months (from 2014 to 2017).

Gene expression, the transfer of the genetic code into cellular proteins is one of the most fundamental processes in living cells. This process is orchestrated by protein-based molecular machines, called RNA polymerases that read the DNA sequence to generate messenger RNA (mRNA), which is translated by the cellular machinery to make proteins. Our cells have evolved elaborate regulation mechanisms to control these molecular machines and a breakdown in this regulation leads to diseases such as cancer. Recently, molecules called myosins have been discovered in the genetic storage compartment of the cell (the nucleus) where they interact with RNA polymerases to regulate protein production. This is interesting because myosins are usually found outside the nucleus transporting cellular cargo or generating muscle contraction. In breast cancer cells, myosin is abundant and interacts with the oestrogen receptor. The majority of breast cancer in the UK is oestrogen receptor positive and activation of this receptor is an important factor controlling the growth of cancer cells. Oestrogen receptor activation appears to be dependent upon myosin and this research project will investigate how myosins are targeted to specific genes and how they are themselves regulated. This will greatly enhance our understanding of the role of nuclear myosins in oestrogen receptor positive breast cancer and may identify a novel therapeutic target for future drug development.

Utilization of circulating-tumor-cell (CTC) and cell free DNA (cfDNA) as novel and noninvasive tests for diagnosis confirmation, therapy selection, and cancer surveillance is a rapidly growing area of interest. In the wake of FDA approval of a liquid biopsy test, it is important for clinicians to acknowledge the obvious clinical utility of liquid biopsy for cancer management throughout the course of the disease.

Study Purpose: A multicenter prospective study to evaluate the outcome of second breast cancer surveillance with abbreviated breast MR (AB-MR) or ultrasound (US) in addition to annual mammography in women with BRCA1/2 mutation testing Study Scheme: AB-MR, US, and digital mammography will be performed on the same day and interpreted independently at baseline and then after 1 year. After completion of study, patients are followed-up for at least 1 year.

Through this prospective clinical trial,the investigators will focus on the relationship between circulating tumor biomarkers (i.e. circulating tumor cells, circulating tumor DNA and other biomarkers) and the status of primary tumor to discuss its application for assessing prognosis and individualized therapeutic direction. Moreover, the relationship between the circulating tumor cell subpopulations based on epithelial-mesenchymal transition and molecular pathological classification of breast cancer will be determined, which may enable the determination of the value of its application in therapeutic decision making.

Our study aims to evaluate the possibility of clinical application of CTDNA detection in samples or peripheral blood of breast cancer patients, so as to act as the new techniques or indicators of early diagnosis, therapy efficiency, or postoperative surveillance of breast cancer.

This study is a multi-center BCCA study that evaluates the impact of the Oncotype DX® assay on the decision making of the treating physician and the patient. The Oncotype DX® assay is a commercially available diagnostic test that aids in a physician's treatment recommendation to a breast cancer patient. The study also has a pharmacoeconomic component.

The investigators have developed an early detection solution for lung and breast cancer. A system which can distinguish between different medical odors based on biosensors. Our product is user-friendly noninvasive, nonradioactive and nontoxic to the patients. The technology enables a high level of sensitivity and provides users with a quick lab response and a simple yes or no answer. The aim of this study is to contribute and detect the patient at the earliest possible stage, in a noninvasive, nonradioactive and nontoxic way. Exhaled breath and urine samples are a promising approach towards future possible lung and breast cancer screening method.

The aim of this study are to to evaluate the knowledge and understanding on tamoxifen theraphy for breast cancer patients and examine the decision conflict scale and satisfaction with decision scale while making decision to take tamoxifen.

Three-dimensional functional Metabolic Imaging (3D MIRA) is a new infrared imaging technology using the Real Imager 4(RI4) developed by Real Imaging. This technology generates 3D metabolic maps and based on sophisticated machine learning technology, provides objective risk assessment for the presence of malignant tumor. The procedure is non-invasive, comfortable and does not involve ionizing radiation. Moreover, Real Imaging's 3D Functional MIRA is unaffected by breast density and is therefore ideal for evaluating patients with mammographically dense breasts. The purpose of this clinical study is to assess the ability of this novel technology to detect clinically occult breast cancer in a cohort of women that are at high risk for breast cancer. We hypothesize that the combination of screening mammography and metabolic screening (3D MIRA) will result in significantly higher breast cancer detection rates.
