The primary aim of this study is to investigate and test whether the use of combined indocyanine green (ICG) lymphography and ultra high frequency ultrasonography can correctly identify lymphatic vessels and venoles in close proximity to each other, for identification prior to lymphovenous anastomosis (LVA) surgery.
Chemotherapy uses anti-cancer drugs to destroy cancer cells and is a common treatment for many cancers. Taxanes are the most widely used chemotherapy drugs given to breast cancer patients. However, taxanes also have toxic side effects. One of the most severe side effects is damage to nerves in the peripheral nervous system; a neurological disorder known as peripheral neuropathy. Common symptoms of peripheral neuropathy are pain, numbness, and tingling in the hands and feet, which can lead to chemotherapy being prematurely discontinued. Unfortunately, treatment options to manage peripheral neuropathy are limited. Exercise has recently been proposed to reduce symptoms, but consistently exercising during chemotherapy is challenging for patients because of treatment-related side effects and fatigue. A more feasible approach may be to exercise on the day before each infusion. This research includes two linked studies that aim to evaluate whether measuring peripheral nerve function at various timepoints throughout chemotherapy and performing aerobic exercise 24 hours before each infusion is feasible and acceptable to patients. In study 1, the investigators will recruit early stage breast cancer patients, who are scheduled to receive taxanes, from medical oncology outpatient clinics. The investigators will ask consenting participants to make 4 or 5 separate visits to the Hospital at various timepoints throughout chemotherapy, depending on the type of chemotherapy they are prescribed. Each study visit will involve completing some questionnaires as well as tests of peripheral nerve function and functional ability. In phase 2, a new cohort of breast cancer patients undergoing the same chemotherapy regimens will be randomly allocated to an exercise group or a control group. The exercise group will be invited to perform a supervised bout of aerobic exercise (30 min of moderate-intensity on a cycle ergometer) one day before they receive chemotherapy. The findings will lay the foundations for future large-scale research.
Breast cancer is a major cause of survival for women worldwide. Neoadjuvant therapy as an important treatment for locally advanced breast cancer has had many positive effects for breast cancer patients. As drug therapy for breast cancer continues to evolve, the percentage of pathologic complete responses continues to increase. However, at present, pCR can only be judged by pathological testing of surgically resected specimens, and the question of whether pCR can be accurately judged preoperatively has become an urgent issue.Therefore, this project plans to establish and validate a model for determining pCR after NAT in breast cancer based on clinical information, imaging and pathological information of breast cancer patients in multiple centers using artificial intelligence technology in accordance with international guidelines and domestic expert consensus on breast cancer NAT, in order to solve the problem of surgical decision making for patients after NAT, by combining experts from breast medicine, surgery, pathology and imaging departments in several tertiary care hospitals across China. The model will be validated to solve the problem of surgical decision making for post-NAT patients.
I this qualitative study, Investigators will conduct semi-structured interviews with clinicians that are involved in the care of patients with breast cancer to evaluate the acceptability, appropriateness, and feasibility/usability of a metastatic breast cancer-specific prognostic tool. These interviews will be conducted by the UNC CHAI Core and will continue until thematic saturation (estimated 10 participants). The investigators will code the qualitative data using emerging themes, guided by a well-established implementation science theory, the Consolidated Framework for Implementation Research (CFIR). The information gained from these studies will inform an implementation approach to increase the usability and acceptability of a novel prognostic tool to assist oncologists in the prognosis of patients with metastatic breast cancer.
This study is a multicenter, randomized, phase 3 clinical trial in patients with breast cancer, randomizing radiotherapy group (postmastectomy radiation therapy (PMRT)/whole breast irradiation plus regional radiotherapy (WBI+regional RT) versus and no PMRT/WBI alone group. This is a non-inferiority study aiming that there is no significant difference in the 7-year disease-free survival rate between the two groups.
This is a multicenter, randomized, double-blind, placebo-controlled Phase III clinical study evaluating the efficacy and safety of FCN-437c in combination with letrozole or anastrozole ± Goserelin versus placebo combined with letrozole or anastrozole ± Goserelin in women with first-line advanced breast cancer in HR+ and HER2-.
This is a multicenter, randomized, double-blind, placebo-controlled Phase iii clinical study evaluating the efficacy and safety of FCN- 437c in combination with fluvestrant ± goseraline versus placebo in combination with fluvestrant ± goseraline in women with HR+ and HER2- advanced breast cancer.
To evaluate the efficacy and safety of chidamide in combination with camrelizumab and carboplatin or capecitabine in the second and third line treatment of relapsed/metastatic triple-negative breast cancer
The purpose of this study is to learn more about the challenges with breast cancer diagnosis in Tanzania and the support available to improve this process.
The standard treatment for breast cancer when cancer cells were found near or within the margins of the tissue that is removed during breast surgery, is radiation of the entire chest wall. This may be considered overtreatment since the only reason for doing so is that cancer cells were near or in the margins of the breast tissue that was removed. In this study, the amount of radiation treatment will be limited to the area where the remaining cancer cells were found after surgery. The purpose of this study is to find out if partial chest wall radiation therapy is as good as whole chest wall radiation therapy in reducing the risk of breast cancer cancer coming back.
