Active clinical trials for "Breast Neoplasms"

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.

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.

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.

The investigators aim to evaluate the possibility of clinical application of CTC 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.

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.

Breast cancer is a frequent pathology and the speed of initial diagnosis makes it possible to improve the course of care and to reduce the anxiety of the patients. For a complete assessment, several biopsies may be necessary, including lymph node biopsies. Once the histological sample has been taken, a preparation is necessary (time consuming technician) then a reading by a pathologist requiring at least 48-72h. Cytology allows immediate diagnosis, but it requires the presence of a pathologist in the collection room. Finally, some biopsies can be non-contributory (if there is not enough tissue removed) and require new samples. A tool allowing immediate control of the tissue and an initial diagnosis without mobilizing the pathologist (who will make the result complete with immunohistochemistry) would make it possible to anticipate the next course of care and facilitate treatment. The BIOPSY SCANNER LLTECH © technology would allow images on fresh unprepared tissue to obtain images allowing immediate diagnosis by a non-pathologist, the same tissue could then be technical for a complete analysis by the pathologist. The investigators propose a study evaluating the diagnostic capacities by non pathologists from images obtained by the BIOPSY SCANNER LLTECH © technology on breast and lymph node biopsies. Based on this study, an atlas on breast lesions could be created to allow a broader evaluation of this technology in daily practice in diagnostic of breast pathology.

Neoadjuvant systemic therapy (NST) is increasingly recommended for patients with early breast cancer, and the rate of patients with pathological complete remission (pCR) is increasing due to the use of modern chemotherapy regimens and targeted therapies, especially in patients with human epidermal growth factor receptor 2 positive (HER2+) breast cancer and triple negative breast cancer (TNBC). It is therefore important to mark a lesion (with e.g. clip) before the start of NST in order to safely identify and localize a clip and (former) tumor bed after completion of NST. Reliable sonographic detection of the clip would be preferred to mammography-guided detection and marking. In addition to avoiding radiation exposure by mammography and reducing time, personnel and financial expenditure, ultrasound-guided wire marking of the clip is less painful for the patient than stereotactic wire marking. The present prospective registry study aims to evaluate how often the intramammary Tumark® Vision clip can be detected by ultrasound after completion of NST in patients with TNBC and HER2+ breast cancer and thus, in the case of pCR, how often the elaborate clipping with mammographic (stereotactic) guidance can be avoided.

Clinical trials are essential to translate new therapy concepts or rather any intervention into the medical routine. Beside the well designed trial protocol, the success of clinical trials depends on patient recruitment and participation. This study aims to get a current picture of the patients' knowledge and perception of clinical trial participation in Breast cancer female patients in Egypt, as an example to Low/Middle income countries.

This study aim to determine kinetic of post treatment recovery/variation of a panel of innate and adaptative immune system cells and molecules. The results should allow to determine the optimal post treatment immunomonitoring timing and panel to be used for future studies.

The purpose of this study is to test an innovative MRI breast cancer screening method in women with mammographically dense breasts as well as other women with moderately increased cancer risk. MRI, combined with other methods of risk assessment, has potential to significantly improve sensitivity to cancer in dense breasts and detect cancer in all cases at a much earlier stage, with far fewer interval cancers than mammography. Previous tests of MRI sensitivity show that this screening could significantly increase the likelihood of detecting invasive cancers resulting in decreased mortality from breast cancer. Suspicious lesions will be defined by the clinical interpretation of the breast MRI images performed by the attending breast radiologists. Based on the radiologist determination that the MRI findings are suspicious (these findings include masses, non-mass enhancement and foci), suspicious lesions will be assigned a Bi-Rads code specifying whether additional work up or biopsy is necessary. These are Bi-Rads codes 0, 4 and 5. False positive diagnosis should be minimized as all attending physicians reading breast MRI at this institution are fellowship trained in breast imaging.
