Active clinical trials for "Breast Neoplasms"

This study is to Assess hypercalciuria between J1 of the cure and 1 J1 6 of the cure of adjuvant chemotherapy in patients receiving conventional adjuvant chemotherapy of breast cancer.

The purpose of this pilot is to provide credible performance estimate information in order to conduct subsequent reader studies.

Docetaxel plus carboplatin and trastuzumab has been a standard treatment for patients with human epidermal growth factor receptor-2（HER-2）positive. The investigators witnessed a higher pathological complete remission(pCR) rate but no obvious increase in cardiac toxicity when used the anthracycline instead of carboplatin. The investigators expect to carry out a large sample size clinical research to optimize the existing therapeutic regimen

The primary aim of this study is to determine if the addition of an individual polygenic risk score (PRS), in addition to the standard National Cancer Institute's Breast Cancer Risk Assessment Tool (BCRAT) or Tyrer-Cuzick (IBIS) score, will aid women at risk of breast cancer in making a decision to take (or not take) medications to prevent breast cancer

This study will examine whether lymphedema after breast cancer surgery can be reduced. In a randomised controlled design the aim is to investigate whether an early intervention with progressive resistance training and close monitoring of arm swelling can reduce the incidence of lymphedema after breast cancer surgery.

The sensitivity and specificity of uPAR PET/CT for preoperative detection of lymph node metastases in breast cancer.

The purpose of this study is to evaluate the role of technologist-performed whole breast ultrasound for detecting breast cancer in the screening population of women with dense breasts.

Breast cancer is a major public health problem. In France, it is the leading cause of cancer death in women. According to the National Cancer Institute (INCA), approximately 49,000 new cases were diagnosed in 2012 in France. It is an heterogeneous disease, comprising a plurality of entities whose clinical behavior, biological and prognosis differ. Amongst these entities, the breast cancer triple negative (TN) is defined by the absence of expression of estrogen receptor and progesterone and the absence of overexpression of HER2 oncoprotein. It represents about 15% of breast cancers and occurs more frequently in young women. This is a very proliferative tumor phenotype with metastatic potential. Because of its genomic heterogeneity and lack of recurrent identified molecular target, no targeted therapy has today shown benefit in terms of survival compared to conventional cytotoxic chemotherapy, which partly explains the very poor prognosis of this tumor phenotype. The positron emission tomography (PET) with 18Fluoro-deoxy-glucose (FDG) is a molecular imaging test that can identify from the first or second neoadjuvant chemotherapy treatment non-responder patients to treatment with low probability of pathologic complete response (pCR) after neoadjuvant chemotherapy. For this two FDG-PET examinations should be performed; a) a pretreatment PET b) a control PET after one or two treatments. The objective of this pilot, single-center, prospective study is a preliminary identification of recurrent genomic alterations among triple-negative tumors with early chemoresistance, identified by PET in the first cycle of neoadjuvant therapy.

The purpose of this study is to determine if a 3-dimensional mammogram (DBT) may provide additional information to evaluate the extent of disease and additional findings that would aid in staging a new breast cancer patient. This would impact surgical planning and improve patient outcomes.

This clinical trial will enroll up to 130 adult women with a confirmed diagnosis of clinical stage 1 or 2 breast cancer who are undergoing breast cancer surgery with lumpectomy or mastectomy and planned axillary sentinel node biopsy procedure. Participants will undergo lymphatic mapping with technetium Tc-99m (99mTc) sulfur colloid in accordance with routine clinical practice. Injections of 99mTc sulfur colloid will take place the afternoon prior to planned next morning surgery or on the morning of surgery. Participants will undergo lymphoscintigraphy in accordance with standard clinical practice. Immediately prior to operation, after the induction of anesthesia in the operating room, up to 1cc of 0.5% indocyanine green (ICG) solution will be injected subdermally close to the tumor or into the subareolar region after disinfection of the breast skin. ICG movement will be facilitated by manual massage and monitored with fluorescence imaging. ICG fluorescence will be elicited and detected by Photodynamic Eye (PDE) camera. The lymphatic drainage, made evident by the fluorescent dye, will be monitored in real time on a monitor. The fluorescence will be followed towards the armpit region (axilla) and time for the fluorescence to reach the axilla will be recorded. Following standard practice, an incision will be made in the armpit region. Fluorescent lymph nodes (ICG positive) will be localized and removed and analyzed by a pathologist. Node removal will continue until no residual fluorescence is visible in the axilla. Removed nodes will be tested for radioactivity using a standard gamma-detecting probe and the counts per minute will be recorded. Finally, the armpit region will be inspected with the gamma probe to determine if there are any residual radioactive nodes. Residual sentinel nodes (the first node to receive lymph from a tumor) will be removed. For the purposes of this study, the sentinel status of a node will be defined as being flagged as sentinel by either one or both of the ICG or 99mTc methods. The goal of the project is to confirm that axillary lymphatic mapping with ICG leads to similar nodes being labeled as sentinel as lymphatic mapping with 99mTc-labeled radiotracer.
