In mainland France, breast cancer is the most common cancer in women, with an estimated incidence of over 58,000 new cases. Even if breast cancer is a cancer with a good prognosis, it is responsible for more than 12,000 deaths per year (first cause of death by cancer in women in France). Breast cancer is a multifactorial disease, which results from the interaction between environmental, lifestyle, hormonal and genetic risk factors. In Reunion, more than 400 cases of breast cancer are diagnosed annually. As in mainland France, it is by far the most common cancer in Reunionese women, and its incidence continues to increase significantly since the age-standardized incidence rate increased by 28% between 2007 and 2017 to establish at 64.2/100,000 AP. Two studies carried out in patients carrying mutations in the breast-ovary predisposition genes in Reunion, showed that more than 50% of patients carrying BRCA mutation have a mutation specific to the Reunion population on the BRCA2 gene. These two studies, which confirm the genetic specificities of Reunion already described in other pathologies (Mucoviscidosis or Friedreich's Ataxia), suggest that this mutation could have a significant frequency in patients with breast cancer. Thus, evaluating the prevalence of this mutation in patients with breast cancer in Réunion would make it possible to adapt the indications for access to the oncogenetics consultation and the associated preventive measures
This study aims to use a combination of abbreviated protocol and artificial intelligence to automatically identify lesions and make diagnosis without decreasing the diagnostic accuracy of breast cancer, thus enhancing the comfort of patient examination, accelerating the flow of examination and reducing the load of clinical work.
In the Netherlands approximately one out of seven women will develop breast cancer during her life. Most of these breast cancers are early stage, 40% of the women have stage 1. Stage 1 breast cancer means that the cancer is small (size <2cm) and only in the breast tissue or it might be found in lymph nodes close to the breast. The standard treatment for stage 1 breast cancer is breast conserving surgery (BCS), sentinel lymph node procedure (SLNP) and additional radiotherapy. This standard treatment protocol results in a10 years survival rate of 95% for stage 1 disease. However, nowadays there is a discussion whether these early stage breast cancer could be treated less invasively. To reduce the invasiveness of breast cancer treatment, without compromising breast cancer specific survival, minimally invasive ablation procedure of the breast tumor can be an option for small breast lesions. Patients with a tumor size<2 cm will undergo ultra guided microwave ablation (MWA) with local anesthesia. After a small incision 2-3 millimeters, an MWA electrode is placed at the end of the tumor with ultrasound guidance. The microwaves in MWA create heat around the needle and destroy the cancer cells. There are several advantages of ablation procedures: it is a minimal invasive technique, with a small or absent cutaneous scar and thereby potentially improving patient quality of life. Furthermore, ablative treatment can be done under local anesthesia and/or conscious sedation instead of general anesthesia and in daycare setting, which can reduce treatment cost. A post procedural MRI (after ablation) can determine whether the ablation procedure of the tumor volume is complete. The purpose of this study is to assess whether minimally invasive microwave ablation (MWA) followed by postprocedural MRI scan can be an alternative treatment for breast surgery in early stage breast cancer. Is the quality of life, the cosmetic outcome, fear of breast cancer recurrence, and costs in patient treated with MWA comparable or better compared to patients treated with breast surgery?
Objective The "Bexa Breast Exam," or "BBE," for the purposes of this study is defined as the use of a Bexa device in conjunction with a portable, focused ultrasound examination ("spot ultrasound") to identify and further evaluate abnormal breast masses including cancer. Commercially, this combination of Bexa plus focused ultrasound is called "Bexa Plus." This study compares the use of the Bexa Breast Exam (BBE/Bexa Plus) as a breast cancer early detection examination with the current standard of care digital breast tomosynthesis. The specific objectives are: 1. To measure the sensitivity and specificity of BBE as compared to digital breast tomosynthesis. 2. Measure the proportion of women receiving a Bexa Breast Exam that require additional imaging studies. Hypothesis The purpose of this study is to demonstrate that Bexa Breast Examination's sensitivity and specificity in identifying abnormal breast masses are equal to or superior than the standard accepted mammography with tomosynthesis.
Breast cancer is the most frequent cancer in women worldwide. Its incidence is increasing but mortality has decreased in a considerable way due to the combined effect of early detection and improvement in treatment . Irisin is encoded by the FNDC5 gene, whose expression is controlled by the peroxi- some proliferator activated receptor gamma coactivator 1 alpha (PGC-1α). PGC-1α is a transcriptional co-activator which does not bind directly to DNA. Studies indicated that the estrogen-related receptor alpha (ERRα) could be a factor that plays a role in PGC-1α binding to DNA. ERRα is encoded by the ESRRA gene and is an orphan nuclear receptor, which has two domains. One of them allows the interaction with DNA, and the second one with a ligand. The ERRα structure is similar to that of the estrogen receptor alpha (ERα), but this receptor does not bind to natural estrogens. ERRα interacts with a canonical sequence of the estrogen response elements (ERRE). ERRα and ERα could compete with each other to bind to similar DNA elements. Together, ERRα binds to DNA, in complex with PGC-1α, to regulate the activity of genes such as FNDC5 . CA15-3, a high molecular weight glycoprotein (300-450 kDa), is produced by the epithelial ducts and acinic breast cells and is then secreted in milk normally. It has been widely used for the prediction of bone metastases in patients with breast cancer .
This is a multicenter, open-label, randomized controlled, prospective clinical study to evaluate the efficacy and safety of Huaier Granules in patients with advanced breast cancer without visceral metastasis.
The purpose of this study is to determine if pharmacokinetics of docetaxel is modified by the body composition (assessed by the BMI but also by CT-scan) in patients treated by docetaxel as adjuvant treatment of a localized breast cancer
Breast cancer is the number one cancer in women worldwide, with 58,500 new cases in metropolitan France in 2018. The announcement of the cancer, the treatment methods and their side effects can generate unpleasant emotions, such as fear, for example, and the resources for coping with them differ according to the patient. Coming to the hospital as an outpatient for chemotherapy is in itself a source of anxiety. The use of music in the treatment process is a therapy that can help patients to reduce the intensity of their unpleasant emotions. Active music therapy involves the patient playing an instrument, including voice and body movement in rhythm, without requiring any musical skills. The presence of a qualified music therapy professional is essential, particularly in the reception of the emotions that may be generated during the sessions. These sessions can be collective or individual. In breast cancer, music therapy has been shown to be effective in reducing pain, anxiety, depressive symptoms and length of hospitalisation in patients undergoing mastectomy.
Health inequities are defined as systemic differences in the health status of different population groups. It is well established that there are many sources of health inequity in oncology including differences in mortality, cancer screening uptake, time to diagnosis and disparities in access to treatment and care. Routine cancer screening and effective surveillance and follow up are some of the most effective ways to reduce the burden of cancer across an individual's lifetime and at the population level. While there is a lack of screening tests for many cancers, breast cancer, the second highest leading cause of cancer death in women, has a plethora of validated screening and risk reduction approaches which can yield earlier detection and effective ways of treating and following women at risk and with breast cancer and improve outcomes. However, there is uneven adoption and inconsistent use of these technologies and care practices. The RISC Registry is an observational study that seeks to understand the application of risk-informed screening and care approaches and pursue the hypothesis that these screening approaches accompanied by population appropriate methods of clinician and patient engagement may increase understanding and compliance with screening, surveillance and follow up recommendations by empowering people to make healthier choices, and support addressing disparities in screening and patient care. The primary focus is cancer screening with a focus on Precision Screening. (Precision Screening attempts to separate those who will benefit from screening from those that may not, through use of information on disease risk.) The study will start by focusing on women and breast cancer risk.
