Serum Estradiol (E2) Levels in Breast Cancer Patients During Endocrine Therapy by High Performance Liquid Chromatography-tandem Mass Spectrometry (LC-MS /MS)
The investigators intend to conduct a prospective cohort study to detect E2 levels during endocrine therapy in Chinese breast cancer patients using LC-MS/MS methods, and to determine the proportion of patients with premenopausal E2 levels (OFR or E2 insufficiency) during AIs or FUL endocrine therapy. To further explore the correlation …
AXillary Surgery After NeoAdjuvant Treatment
The optimal surgical axillary staging technique in patients who convert from the clinically positive to clinically negative lymph node status under neoadjuvant therapy (cN+ → ycN0) remains to be clarified. Different strategies (axillary lymph node dissection, sentinel node biopsy, targeted axillary dissection) are currently used in different countries. A prospective …
Psychological Well-being in Patients With Breast Cancer
Psychoncological evaluation in patients diagnosed with breast cancer is often limited to psychological distress and does not include evaluation of individual resources. This assessment could contribute to implement adherence to treatment protocols and eventual post traumatic growth. This study shows a new model of psychoncological triage by screening the risk …
Identification of Breast Cancer in Breath Samples Using Trained Detection Dogs
The goal of this study is to find out whether a system that uses trained detection dogs and artificial intelligence (AI) can identify breast cancer from a person's breath. Women who are scheduled to have routine breast cancer screening, such as a mammogram, ultrasound, or a biopsy for a possible …
Regional Radiotherapy Omission in Low-Risk Node Positive Breast Cancer
The purpose of this study is to determine whether certain patients can safely omit regional lymph node radiotherapy. These women must have hormone-sensitive, Her2-negative tumors, have 1-3 positive axillary nodes and have RecurIndex low-risk.
Precision Retrospective Integrative Study for Metastatic Lymph Nodes in Breast Cancer
Accurate assessment of axillary lymph nodes in patients with breast cancer is essential for prognosis and treatment planning. Staging and surgical management have evolved from axillary lymph node dissection to sentinel lymph node biopsy to minimize morbidity. However, sentinel lymph node biopsy has non-negligible morbidity, and more than 70% of …
Registry of Adjuvant Hormone-blockade Breast Cancer Patients Evaluated for Bone Mineral Metabolism
Establishment of a registry by which to census all patients treated with adjuvant hormone blockade for previous breast cancer in order to evaluate in future studies the trend of bone mass and its relationship to laboratoristic indices inherent in calcium metabolism, and the prevalence and incidence of fractures.
The Association Between Plasma Metabolites and the Risk, Efficacy and Prognosis in Early Breast Cancer
This study investigates plasma metabolites to clarify the relationship between these metabolites and breast cancer, aiming to identify valuable biomarkers. Furthermore, by incorporating clinical information-such as cancer stage, type, treatment outcomes, and prognosis-into prospective studies, the research seeks to further examine the correlation between plasma metabolites, treatment efficacy, and prognosis.
Bergonie Institute Breast Cancer Database
A database of breast cancer patients was established at Institute Bergonié since the 90s , to assess patients' survival, assess practice, search for prognostic factors.
Breast Reconstruction and Radiotherapy
If the whole breast is removed because of breast cancer, several options for breast reconstruction are available. All these options have an increased complication risk if a patient has been or will be treated with radiotherapy. However, only a few high-quality studies addressed patient satisfaction and complication risks, both in …
