Active clinical trials for "Breast Neoplasms"

The main objective of the study is to assess the feasibility of a coached physical activity program in the form of an accompanied and adapted water polo program by evaluating the interest aroused in patients for this proposal. treatments (number of participants and sessions performed).

The prescription of neoadjuvant chemotherapy becomes a standard in women with HER2-positive or triple-negative breast cancer and allows a complete histological response (pCR) which represents a prognostic factor for survival. . The problem for patients who are not pCR is that they are currently receiving non-personalized adjuvant systemic treatment. The identification of biomarkers present in the residual disease would be a criterion to guide the choice of post-neoadjuvant adjuvant systemic treatment, in order to personalize it. At the present time, there is no published study describing extensively the immune micro-environment (ME) in breast cancer, whether before or after chemotherapy, nor its modification induced by chemotherapy. The team therefore propose to study in a retrospective and monocentric series, the modifications of the immune ME induced by a "standard" neo-adjuvant chemotherapy in patients with triple-negative CS, whether they are in complete histological response or not (n = twice 50). The main objective of this project is to describe the changes in the immune ME of triple-negative breast cancers induced by neoadjuvant chemotherapy for all patients (in pCR or not): Quantification of TILs and subtypes of TILs (CD4 and CD8) Expression of the three immune checkpoints that are PDL1, TIM3 and LAG3 Describe the organization of the immune system (immunostaining on the same slide of the PDL1, TIM3 and LAG3 immune checkpoints)

This is a single arm, compassionate use study with 30 patients for leronlimab (PRO 140) combined with a treatment of physician's choice (TPC) in patients with CCR5+ mTNBC.

Breast cancer is the most common cancer of women. Surgery for early breast cancer includes axillary lymph nodes staging. Axillary surgery may lead to intractable complications like permanent arm swelling. Axillary sentinel lymph node biopsy (SLNB) has been introduced to minimize the incidence of these complications. Several methods are routinely used for identification of the sentinel node during operation. Some of these methods necessitate facilities that are not universally available; specially in countries with limited resources. In its simplest form, SLNB using the methylene blue dye technique has an identification rate of 88-94%. If the sentinel node can not be identified, full axillary dissection may be required and the risk of arm swelling is increased. The objective of this study is to maximize the identification rate of the sentinel node thus avoiding the need for extensive axillary surgery. The investigators assumed that preoperative tattooing of the suspicious lymph node during ultrasonographical imaging may help the surgeon in localizing the sentinel lymph node. In this study, the sonographer will perform preoperative tattooing of the suspicious node. The surgeon will perform SLNB by the methylene blue dye. The sensitivity of ultrasonographical tattooing relative to SLNB will be calculated. The study will determine if the tattooing technique may localize additional nodes that are missed by the methylene blue.

The purpose of this study is to determine the clinical performance of AI-based Thermalytix with the current standard-of-care diagnostic modalities in women.

Breast cancer (BC) is the most common cancer diagnosis among women and the incidence is increasing. Prognosis and treatment are dependent on the expression of estrogen receptors (ER) in the tumor. ER status is determined by immunohistochemistry (IHC) on biopsy tissue. The ER expression can change over time and be heterogeneous. The IHC score on ER expression is subjective and can lead to intra and inter observer variability. A new computer image analysis software that can give the exact percentage of colored tumor cells on sectional tumor cuts has been developed. It is also possible to quantify the ER expression non invasive by using the tracer 16α-18F-flour-17β-estradiol (FES) and in vivo positron emission tomography (PET) scans. FES-PET/CT has a high background activity in the liver which complicates the visualization of liver metastases. Theoretically, a new whole body parametric scan method makes it possible to distinguish background activity from uptake in liver metastases. Malignant tumors often have an increased perfusion, and previous studies have found that tumors with low metabolism relative to blood flow have the longest disease free survival (DFS). To the best of our knowledge, no previous studies have examined the correlation between ER expression and blood flow.

Breast cancer is the most common cancer in women worldwide, especially in developed countries. In developing countries, including South Korea, the incidence and mortality rate of breast cancer is rapidly increasing. One of the most important characteristics of breast cancer in South Korea, as well as in other Asian countries, is the younger onset of disease compared to Western. Medical treatment of breast cancer is evolving rapidly, incorporating immune checkpoint blockades and molecularly targeted agents. However, data and knowledge are still limited in terms of molecular characteristics of Asian breast cancer, compared to that of Western countries, and this remains a major hurdle for drug development in Asian breast cancer patients. The primary objective of this study is to elucidate the genetic characteristic of young (<50 years of age) Korean patients with metastatic breast cancer using FoundationOne CDx.

The purpose of this study is to identify the combined impact on bone loss as well as the incidence of bone fractures in women with estrogen receptor (ER)-positive, early breast cancer treated with an aromatase inhibitor (AI) either as first line therapy or as maintenance therapy after initial treatment with chemotherapy, in real life clinical settings in Greece.

Cancer Survivor Registry: The Breast Cancer M.A. P. (Mind Affects the Physical M.A.P.) Project to identify and help us understand the emotional and social needs of breast cancer survivors.

The purpose of this study is to study if a patients follows an exercise program specifically designed for them during the time of their treatment after surgery. Their ability to follow the program and its influence on their weight maintenance and early post-operative lymphedema rates will also be studied. Lymphedema is a condition in which excess fluid collects in tissue and causes swelling of the arm(s).
