Active clinical trials for "Breast Neoplasms"

The overall goal of this study is to determine how FDG-PET, breast MRI and breast ultrasound can be incorporated into the assessment of treatment responses in women with LABC undergoing neoadjuvant chemotherapy. A prospective cohort study will be conducted evaluating the ability of FDG-PET, breast MRI and breast ultrasound to detect the presence of residual tumour in patients with LABC who have completed treatment with neoadjuvant chemotherapy prior to mastectomy.

Goals of this registry: 1.1 To collect and store very limited demographic information (age, birthdate, race and ethnicity), limited cancer risk and breast and ovarian disease history, as well as limited family history of breast and ovarian cancer on patients who are at risk of breast or ovarian cancer or who have had a diagnosis of either cancer, 1.2 To make available summary information (in an anonymous form) regarding the subjects in this registry to Consortium members, and other investigators, who can use these data to plan research projects and evaluate the feasibility of such projects, 1.3 To make available summary information (number of new patients seen in the clinic, number of mutations, number of preventive surgeries, average age of patients seen) to the Lynne Cohen Foundation for Ovarian Cancer Research, in order to document the numbers of subjects who utilize their supported clinics.

In patients with breast cancer who undergo neoadjuvant chemotherapy or neoadjuvant hormone therapy molecular breast imaging (MBI) is an accurate test for assessing response rate to neoadjuvant therapy.

This study is being done to test the ability of an investigational mammography camera to find small tumors in patients' breasts.

The risk of deep venous thrombosis after radical breast surgery is known. The objective of this study is to explore hypercoagulability after radical breast cancer surgery by studying several factors for haemostasis before, during and after surgery. Ultrasound Doppler examination is realised between 24 and 72 hours post-operatively. Hypercoagulability is defined by a significant increasing level of thrombin-antithrombin, D-dimer and the endogen thrombin potential.

To screen women who are high risk for breast cancer with breast MRI, mammogram and random periareolar fine needle aspiration.

To investigate whether digital breast tomosynthesis (DBT) benefits survival improvement.

Breast cancer is the most common type of cancer in women and the second most common cause of death after lung cancer. In epidemiological studies, its prevalence is 22-26%, and the mortality risk due to breast cancer is around 18%. It is known that the immune system has an important role in tumor development or tumor destruction. Recent studies have shown that tumor cells acquire escape mechanisms to escape host immunity in the tumor microenvironment. Studies have reported that immune checkpoints are elevated in many types of cancer and have a poor prognosis. Up or down regulation of immune checkpoints is observed to protect breast cancer cells from the anti-tumor responses of the immune system. There are also immune checkpoints found in plasma in soluble form, and the number of studies evaluating soluble immune checkpoints in cancers is very limited in the literature. Measurement of soluble immune control points is easier than those expressed on the surface, and many markers can be evaluated at the same time. There are very few studies in the literature evaluating soluble immune checkpoints in breast cancer. The aim of this study is to investigate the role of soluble immune checkpoints in predicting the response to neoadjuvant therapy in locally advanced breast cancers.

The study is composed of three paper self-questionnaires to be filled in by the patients included at distance (> 6 months) from their diagnosis of metastatic breast cancer, in order to limit the impact of the announcement on the filling out the questionnaires. After verification of the eligibility criteria, the medical oncologist will present the study to patients coming to the ICL for a follow-up consultation as part of their regular care. The patients will meet with a clinical research nurse so that she can explain the again and answer any questions they may have. She will also give the patients the questionnaires questionnaires and will give a presentation of the questions asked. After this meeting, the patients will be given sufficient time to reflect on, which may extend until their next visit to the ICL, in order to express, if they wish, their opposition to participating in the study. If she agrees to participate, the patient can then complete the questionnaires as well as the complementary questionnaire and place them in a closed envelope to be given to the clinical research nurse. The completion of the questionnaires will be completely anonymous. The data of those who object to the use of their data will be deleted from the database. After the completion of the questionnaires, and in order to allow a benefit for the patient, a semi-directive interview in the form of a teleconsultation with a psycho-oncologist and sexologist will be offered. The interviews are not mandatory. The time to fill in the self-questionnaires is estimated at 30 minutes and the semi-directive interview can last up to one hour. Finally, at the end of the study, as part of her subsequent care, each patient participating in the study will have the possibility to renew a teleconsultation with the psycho-oncologist and sexologist if she feels the need. As the subject of the study may generate personal questions and lead to a request for psychological and/or sexological care.

This study aimed to determine whether sentinel lymph node biopsy (SLNB) could be a reliable option for evaluating nodal status in patients who had responded well to neoadjuvant systemic therapy (NAST), even if they had initially presented with a high nodal burden. The study investigated the outcomes of SLNB followed by axillary lymph node dissection (ALND) in this patient population, taking into account the response to NAST and the breast cancer subtype.
