Active clinical trials for "Breast Neoplasms"

breast cancer occurred 19,219cases in 2015 and is the second most common cancer among female cancers in the country. despite there's been a disease understanding and treatment developing through study, the prevalence and mortality of breast cancer have increased steadily over the last 15 years. In the last 20 years, through random clinical studies of breast cancer, radiation therapy is well-established standard therapy as postoperative supplement of invasive breast cancer and intraepithelial carcinoma but, the need for further study with new questions about radiation therapy has been raised through these studies. according to the prospective study outcome, the radiation treatment of the regional lymph node in breast cancer patients with lymph node positive increases the free-disease survival rate, radiation therapy for regional lymph node is being actively treated than in the past. on the contrary, the results of another study are being reported that treating regional lymph node may increase the risk of arm edema, radiation pneumonia and heart toxicity. In the recently, due to advancement in radiation therapy technique, the implement of new radiation therapy such as IMRT that reducing radiation dose to normal tissues of the axillary, lungs, heart and others has been actively attempted. additional research is needed on dose-fractionation schedule, regional lymph node treatment, post-treatment toxicity of radiation therapy in breast cancer. this study establishes a prospective cohort at breast cancer patients with radiation treatment and analyze the local and regional lymph node control, recurrence, toxicity, radiation planning, clinical data, discover the factors that predict local control, regional control, overall survival, recurrence-free survival, toxicity for treatment, so we intend to construct basic data that establishes a radiation treatment strategy based on comprehensive outcomes and predictors.

The primary aim of this study is to determine if the addition of an individual polygenic risk score (PRS) in addition to the 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.

Sentinel lymph node biopsy (SLNB) has become the standard procedure for staging of patients with clinically node-negative breast cancer. Breast-conserving surgery (BCS) has also been a standard treatment for patients with early breast cancer. However, approximately 10% of patients with BCS develop ipsilateral breast tumor recurrence (IBTR), and mastectomy or resection of the recurrent tumor is generally performed. There are no specific guidelines available regarding staging and treatment of the regional lymph nodes. However, the reported risk of axillary lymph node metastasis among patients with local recurrence after breast surgery and a previous negative sentinel node biopsy of 26 % is too high to be ignored. Moreover, evaluation of the regional lymph node basins might be helpful to decide on the indication for adjuvant radiotherapy and systemic treatment. For these reasons it seems sensible to perform a regional lymph node staging procedure in patients with locally recurrent breast cancer. In general practice, this would mean that patients with recurrent breast cancer and a previous negative sentinel node biopsy would receive an axillary lymph node dissection (ALND) and that patients with a previous ALND would receive no additional axillary staging. Lymphatic drainage after previous breast surgery and/or radiotherapy would be altered and it remains questionable whether SLNB at the time of surgery for IBTR (second SLNB) is technically feasible and ALND can safely be omitted. In this study, investigators propose for all patients the realization of SLNB procedure and systematically ALND whatever the results of SLNB analysis, only on patients previously treated with breast conservative surgery. The aim of this study is to evaluate on a homogeneous prospective multicentric cohort of patients the feasibility and the accuracy of a second SLNB procedure for IBTR.

An open-label, single center study with 99mTc-DARPinG3 SPECT/CT and biopsies of primary tumour and metastatic lymph nodes in breast cancer patients, where the primary endpoint of the study is to find out the correlation between the HER2 expression measured by 99mTc-DARPinG3 SPECT/CT and standard histopathology from relevant tumor and lymph node biopsies.

Sometimes, breast ultrasound and mammographic can't be diagnose suspsious lesions ( no substratum). So a MRI-guided breast biopsy is perfomed and disclosed ultimately benign lesions. The aim of this retrospective study is to establish a predictive MRI score of occult breast lesions by mammography and ultrasound.

To assess the role of different combinations of (oncoplastic) surgery and radiotherapy techniques as risk factors for moderate to severe fibrosis and for moderate to poor cosmetic outcome.

In first-line metastatic breast cancer, the bevacizumab-taxane to progression or toxicity, is currently the standard treatment. In patients expressing hormone receptors, it was shown that hormone therapy administered in maintenance after induction chemotherapy, could have a benefit regarding the progression-free survival. The investigators make the hypothesis that there would be interest to discontinue treatment with taxane after 4 months, and to begin hormone therapy while continuing maintenance bevacizumab. Exemestane was chosen because it has been shown potentially active in patients who progressed after letrozole, anastrozole or tamoxifen.

Evaluate the survival without metastasis in patients treated by Trastuzumab in association with other chemotherapies for a breast cancer expressing HER2-NEU.

Many breast cancer patients (BCP) will gain weight during chemotherapy and about 10% of them are able to find back to their initial weight after all treatments are finished. Other studies have shown that overweight at diagnosis was associated to a twice higher risk of relapse while a weight gain during treatments increased by 30% to 50% the risk of relapse. In western countries, 75% of BCP have insufficient physical activity. Dietary and activity programs seem to be able to significantly reduce the mortality risk after breast cancer. The investigators performed a prospective randomized trial consisting in dietary counseling, physical training and physiotherapy in hydrothermal centers. Intervention were delivered in small group session lasting 12 days. SPA cares were offered to patients. Patients in the control group also received dietary counseling given by a dietetician inside anticancer hospital, and were asked to perform more physical activities. Main endpoints of the trial addressed quality of life (SF36) one year after inclusion, weight reduction, anxiety/depression (HAD), sleep quality and long term compliance to instructions. An economic study was associated to the protocol, for volunteers only.

The purpose of this study is to identify new treatment regimens with better response rates and to find out if the combination of cisplatin and sorafenib followed by paclitaxel and sorafenib can shrink the size of your breast tumor and allow you to preserve your breast. Sorafenib is a newer drug that targets blood vessel formation and may help the chemotherapy work better. Additionally, by receiving chemotherapy before surgery, we will be able to determine if your cancer is responsive to chemotherapy.
