Active clinical trials for "Breast Neoplasms"

This is a prospective, open-label, within-patient clinical trial to determine the accuracy of Indocyanine green (ICG) guided sentinel lymph node biopsy (SLNB) compared to the standard dual-tracer SLNB in breast cancer patients who have had chemotherapy as a first treatment using a non-inferiority design. Patients with operable breast cancer treated with chemotherapy and eligible for SLNB will be included in the study. During surgery, ICG will be injected and used to identify fluorescent sentinel nodes using a hand-held imaging camera; radiotracer and blue dye will also be used as per standard protocols. Intraoperative and clinicopathologic outcomes such as complications, characteristics of nodes, false negative rates and feasibility will be assessed. Patients will be asked to complete standardized patient reported outcome questionnaires (Breast-Q, FACT-B+4, VAS) to define the patient experience with this novel technique.

The goal of this clinical trial is to compare the therapeutic effects of chemotherapy followed by surgery and surgery followed by chemotherapy in patients with locally advanced breast cancer（LABC). Patients with LABC will be randomly divided into two groups, each receiving chemotherapy followed by surgery or surgery followed by chemotherapy. The main comparison was between the disease-free survival (DFS) of two groups of patients, with the secondary study endpoint being overall survival (OS); Five year survival; Local recurrence or distant metastasis rate.

Breast cancer is the leading cause of mortality in women worldwide. Latin-American women are diagnosed at younger ages, in advanced stages, and with aggressive molecular subtypes. Lifestyle seems related to these aggressive conditions and worse outcomes. The present study seeks to evaluate the effect of a hybrid multidisciplinary intervention for implementing a healthy lifestyle to modify the personal and internal exposome of young women with breast cancer. This randomized controlled experimental study with two groups: Group 1: Hybrid multidisciplinary lifestyle education intervention. Group 2: Individualized hybrid multidisciplinary lifestyle interventions. The multidisciplinary lifestyle intervention program includes oncology, nutrition, physiotherapy, and psychology interventions.

Compare the efficacy and safety of Dalpiciclib combined with aromatase inhibitors versus chemotherapy as a neoadjuvant therapy in Luminal B/HER2-negative breast cancer, and explore the predictive biomarkers of the response to the two neoadjuvant therapies.

A study to learn about a new medicine called ARV-471 (PF-07850327) in people who have advanced metastatic breast cancer.

Radiotherapy after breast conserving therapy plays an important role in early stage breast cancer patients. It not only results in a reduction in local and regional recurrence but also decrease the death rate effectively. For adjuvant radiotherapy, supine positioning is the most common approach and has multiple advantages. Due to deformability and softness of the breast, during simulation and treatment in supine position, the breast stretches over the chest wall, especially in patients with large and pendulous glands. Thus the organs at risk (OARs) received dose increased. The radiotherapeutic toxicity are unavoidable. Some present studies show that the prone positioning of patients can improve dose homogeneity and reduce the dose distribution in OARs in patients with large and pendulous glands. Chinese women have relatively small breasts, the advantages of those have not been established. Therefore, investigators compared the parameters between supine and prone positions for whole breast irradiation after conserving surgery.

Women aged 70 years or older, newly diagnosed for locally advanced unilateral breast cancer, with a histological diagnosis of invasive mammary carcinoma, positive hormone receptors, HER2 status Negative, not immediately operable (stage of disease, comorbidities or refusal of surgery) with tumor in place, with indication of treatment with hormone therapy and hypofractionated radiotherapy, not eligible for neoadjuvant chemotherapy and without major comorbidity contraindicating the proposed treatment regimen.

To learn if sacituzumab govitecan and pembrolizumab, when given before surgery, can help to control early-stage triple negative breast cancer that has not responded well to other treatments.

This study is planned to include 80 patients with HRD positive HER2-negative advanced breast cancer to receive fluzoparib alone or fluzoparib combined with camrelizumab to observe and evaluate the efficacy and safety of fluzoparib combined with or without camrelizumab in the treatment of HRD positive HER2-negative advanced breast cancer.

Olaparib, a PARP inhibitor, is proven as an effective therapy for germline BRCA1/2-mutated breast cancer; however, the therapeutic efficacy for somatic mutation in BRCA1/2 or genes of homologous recombination DNA repair is unclear. Maintenance of Oalaprib can delay the disease progression in patients with BRCA1/2 mutated advanced ovarian cancer after treatment with platinum based chemotherapy. The investigators design a phase 2 study to evaluate the efficacy of maintenance of Olaparib in patients with metastatic breast cancer. The investigators enroll patients with metastatic ER(+)Her2(-) or triple-negative breast cancer. Patients who are chemotherapy-naïve or prior 1-line chemotherapy are eligible for screening. All eligible patients will receive 4 cycles of platinum based chemotherapy. Gene test will be performed on their breast tumor. If patients have mutation of HR genes and at least stable disease after platinum based chemotherapy, they will be randomized to treatment arm (Olaparib maintenance) or control arm (continuation of chemotherapy). The primary end-point is progression-free survival, and the secondary end-point is to assess the response rate, overall survival and quality of life.
