Filter by:This phase II trial studies the side effects of talazoparib when given before standard therapy in treating patients with breast cancer that has spread to nearby healthy tissue and has a mutation in a breast cancer, early onset (BRCA) gene. Talazoparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth, and may be especially effective in patients with BRCA mutations. It is not yet known whether adding talazoparib before standard treatment is safe in treating patients with BRCA mutated breast cancer.
Background/Main objective: Radiofrequency ablation (RFA) is a minimally invasive procedure widespread accepted in the treatment of different tumors, especially in the liver but its benefit is not yet well-known in breast cancer. Our main objective is to evaluate the usefulness of RFA in < 2cm malignant breast tumors to reduce the proportion of positive margins. Methodology: The investigator propose a single-center, single-blind, phase I and II randomized controlled trial. Phase I:Security of the cool-tip cluster electrode assessing the potential adverse effects in three stages: initial,intermediate and final. Phase II: Randomized clinical trial, 2 parallel groups with 37 patients in each one. Experimental group: percutaneous RFA previous to conventional lumpectomy. Control group: conventional surgery with lumpectomy. The number of positive margins in both groups, and the need of extending margin resection will be assessed intraoperatively. Inclusion criteria: women >40 years, infiltrating ductal breast carcinoma by biopsy. The tumor must be unique, visible by ultrasound, smaller than 2cm and located > 1 cm from the chest wall and the skin. Patients will be followed up for a period of two years to assess cosmetic result, short -term and long -term complications and recurrences. Expected results: The "cool-tip" (cluster) ablation method reduces by at least 30% the risk of intraoperative extensions for positive margins during lumpectomy compared to conventional surgery in breast tumors with a diameter < 2 cm. Therefore this procedure may reduce the risk of second surgeries and the removed volume of tissue.Consequently the final cosmetic result should be improved.
Adjuvant radiotherapy after lumpectomy allows a local long-term control of the order 85 to 95% with a survival rate equivalent to that of the totally mastectomy. The diminution of the local recurrence rate after irradiation post- lumpectomy is also associated to a best global survival than only the surgery. The adjuvant radiotherapy after partially or totally mastectomy for the progressive tumors is a therapeutic standard (Early Breast Cancer Trialists' Collaborative Group 2011). The aim of our trial of routine care is to record our practices under this breast adjuvant radiotherapy.
The need to understand LABC is especially compelling in populations and countries with limited resources, where breast cancer incidence is relatively low, but mortality is comparably high. In these settings access to appropriate cancer care is characteristically limited or often plainly nonexistent. In contrast to economically developed nations, where on average fewer than 20% of women present with breast cancer at advanced stages, LABC and metastatic disease are the most common stages at presentation in 50% or more women in Latin America, Asia and Africa.
The sentinel node has a fundamental role in the management of early breast cancer. Currently, the double detection of blue and radioisotope is recommended. A radioactive material requires the presence of a nuclear medicine department and the approval of health authorities. In many centers, this technique is not available. The use of blue is easier to implement technique. However, allergic reactions and prolonged breast tattoo led many teams to stop the practice. So in common practice, many center use a single method. However, with a single detection, the risk of false negatives and the identification failure rate increased to a significant extent and the number of sentinel lymph node detected and removed is not enough. Under these conditions, find another method of detection seems crucial. According to the literature, the fluorescence method (ICG) is a technique that seems safe and reliable. The investigators therefore propose a prospective, randomized study to investigate the interest of fluorescence associated with the isotopic method.
The purpose of this study is to determine whether it is feasible to give a combination of Metformin and omega-3 fatty acids for one year to women with a history of early stage breast cancer. We will also evaluate whether the metformin and omega-3 fatty acids combination causes changes in breast tissue, blood, and mammograms.
The purpose of this study was to determine whether treatment with tamoxifen or a non-steroidal aromatase inhibitors (NSAI) + goserelin + LEE011 prolonged progression-free survival (PFS) compared to treatment with tamoxifen or a NSAI + goserelin + placebo in premenopausal women with hormone receptor positive (HR+), human epidermal growth factor receptor 2 negative (HER2-) advanced breast cancer.
The purpose of this study is to test whether a radiotherapy regimen of 8 GY x 3 days over 5 days (every other day) is as safe (well-tolerated) and effective as 6 Gy x 5 over five consecutive days
This clinical trial assesses whether a newly designed algorithm which looks at the genomic signature of each patient's tumor to predict their sensitivity to standard of care treatment verses being placed on a personally designed treatment trial can improve the responses in patients with newly diagnosed triple-negative breast cancer (TNBC). Testing the primary tumor biopsy for certain proteins and monitoring the lymphocyte infiltration into the tumors may help doctors determine the sub-type of TNBC, and direct treatments that may work well. It is not yet known whether assigning treatment based on the patient's tumor classification will improve how well the tumor responds.
Breast cancer surgery is associated with presurgical psychological distress and clinically significant side effects including postsurgical pain, nausea and fatigue. A few studies have examined how to intervene to assist women undergoing breast cancer surgery. For example presurgical hypnosis has been proven to decrease side effects and even intraoperative anesthesia use. Besides the more psychologically based interventions there are a few studies suggesting positive effects of acupuncture on pain, anxiety and nausea in surgery patients.This study aims to investigate whether a presurgical relaxation training, acupuncture treatment or a combination of both therapies is able to reduce presurgical psychological distress an postsurgical side effects in breast cancer patients in comparison to usual care.
