Active clinical trials for "Breast Diseases"

This is a randomized, double-blind multicenter Phase III study for evaluating the efficacy and safety of neoadjuvant pyrotinib and trastuzumab plus docetaxel and Carboplatin versus placebo and trastuzumab plus docetaxel and Carboplatin given as neoadjuvant treatment in HER2 positive early stage or locally advanced breast cancer.

The purpose of this study is to evaluate the efficacy and safety of Xiaoru Sanjie capsule in the treatment of cyclomastopathy.

Breast reconstruction is a common procedure with over 86,000 breast reconstruction procedures performed in the United States in 2009. This is a 1.5-fold increase since 2007. Of these breast reconstructions, 65% use a tissue expander/implant technique. Although satisfactory results can be achieved with a single-stage technique, a two-stage approach is considered more reliable, allowing for precise positioning of the inframammary fold and an opportune time to perform a capsulotomy to increase the breast skin flap by releasing the soft tissue. The placement of the tissue expander and implant under the chest muscles is thought to minimize the incidence of capsular contracture, expander exposure, and in addition, produce acceptable aesthetic results. However, discomfort is often associated with this submuscular placement of a tissue expander or implant, specifically during the expansion phase. Patients undergoing immediate reconstruction using submuscular implants have been shown to have higher analgesic requirements and to have higher pain scores post-operatively, compared to non-reconstructed patients. An uncomfortable reconstruction can lead to under-filling of the expander, a longer expansion process, abandonment of reconstruction, and a compromised quality of life. The use of Botulinum Toxin A (Botox) injections into the chest muscles at the time of surgery may help ease the discomfort that is often associated with this procedure. The investigators propose a prospective double-blind randomized placebo-controlled trial of patients undergoing tissue expander/implant reconstruction. The information gathered from this analysis will provide a greater understanding of the effects of Botox in the setting of two-stage tissue expander/implant breast reconstruction, with the goal to improve patient satisfaction and quality of life.

History of clinical breast pain for at least the last six months. At least six days of moderate or severe breast pain per cycle. Fibrosis, cysts, nodules involving at least 25% of the surface of one breast. Euthyroid with no prior history of thyroid disease. Six months of daily therapy with molecular iodine. Placebo controlled vs active (1:1).

It is a phase III trial to explore the efficacy and safety of metronomic chemotherapy with Capecitabine versus intermittent Capecitabine as maintenance therapy following first-line Capecitabine plus Docetaxel chemotherapy in treatment of HER2-negative metastatic breast cancer(mBC).

The study will determine the sensitivity, specificity, negative predictive value and positive predictive value of the OSNA Breast Cancer System for patients receiving Sentinel Lymph Node biopsies after receiving neoadjuvant hormonal/chemotherapy as compared to permanent section Hematoxylin and Eosin (H&E) and Immuno-histochemistry (IHC) staining.

This study will look at effects the combination of palbociclib and dose-dense neoadjuvant chemotherapy may have on triple negative breast cancer tumours which have not yet been treated.

In this study, participants, who are scheduled to have a breast biopsy, will have several extra spot mammogram images taken of the suspicious area. These images will be acquired with varying levels of compression. The images will then be analyzed to determine whether the type of lesion (malignant or benign) can be determined from the image data alone. The biopsy results will be used as a gold standard to determine the true malignancy status

Some women with breast cancer have their whole breast removed as part of their treatment (mastectomy). Of these women, around 31% have more surgery to create a new breast.There are two main ways to create a new breast(i)using tissue from elsewhere on the body ("autologous" reconstruction )or (ii)using a silicone implant. In recent years, it has been reported that by using a material called an "acellular dermal matrix" (ADM) the results of breast reconstruction surgery using an implant can be improved. ADMs are materials which originally come from animal or human skin. They act like a sling, supporting the lower part of an implant beneath the skin. Although ADMs have been approved for used in breast reconstruction and are safe, there is very little high quality evidence to back up their reported benefits, and some studies have suggested their use may in fact increase complications. The main purpose of this study is to find out what the actual risks and benefits of using an ADM in breast reconstruction surgery are. The investigators will follow the progress of women who have an implant based reconstruction to observe if participants develop problems; what those problems are and how participants feel about the results of their surgery. The investigators also follow the progress of women who undergo autologous reconstruction or alternative reconstructive techniques using an implant for the same reasons.

The purpose of this study is to demonstrate that BVN G-1000 can precisely and consistently measure the position of female breast lesions regardless of patient rotation and probe angle during ultrasound examination.
