Audit of Targeted Sentinel Node Biopsy (TSNB) in Patients With Limited Nodal Disease Undergoing Primary Surgery
Axillary ultrasound scan (AUS) is routinely employed in the UK for preoperative axillary staging and can diagnose approximately 50 - 80% of node positive patients when combined with percutaneous needle biopsy techniques (either core-biopsy or fine-needle aspiration cytology). It is recognised that nodal burden is generally higher in clinically node …
The Effect of Neoadjuvant Chemotherapy on Physical Functions
The aim of this observational study was to investigate the effect of neoadjuvant chemotherapy on physical functioning in individuals with breast cancer. The main question that the study aims to answer is how the physical functions of individuals are after neoadjuvant chemotherapy. Demographic information of the participants will be recorded …
Real-World Study on CDK4/6 Inhibitors Combined With Endocrine Therapy and Subsequent Treatment in HR+/HER2- MBC.
Exploring the Efficacy and Safety of Different Systemic Treatment Regimens after CDK4/6i Progression in the Real World has significant implications. This study is an observational, real-world study. It plans to include over 300 eligible HR+/HER2- metastatic breast cancer patients who are currently receiving or planning to receive endocrine therapy regimens …
RADIomics to Predict HER2 Status And T-DXd Efficacy in Metastatic Breast Cancer: the RADIOSPHER2 Study
RADIOSPHER2 study is a monocentric, retrospective, observational study aiming at identifying a radiomics signature able to predict HER2 expression (0 vs low vs overexpression) and trastuzumab deruxtecan efficacy in metastatic breast cancer patients. The study also encompasses translational analyses and inter-modal correlations in order to provide novel insights about HER2 …
Prospective Observational Study on Outcome of High-precision Hypo-fractionated Radiotherapy in Metastatic Breast Cancer (PRECISE-M)
This study is a prospective observational study on outcomes of high precision hypo-fractionated radiotherapy in breast cancer with distant metastasis.
Postoperative Re-irradiaTion With and Without HYPERthermia: Toxicity, Quality of Life and Survival in Patients With Locoregional Recurrent Breast Cancer
In the Netherlands, breast cancer patients with locoregional recurrence (LRR) and high-risk factors are treated with postoperative re-irradiation with or without hyperthermia. Retrospective studies showed that 3-year locoregional control after postoperative re-irradiation with hyperthermia was 68-83%, and severe toxicity in up to 40% of LRR patients. Unfortunately, no prospective (randomized) …
Molecular Residual Disease Assessment in a Diverse Population of Patients With Early-stage Breast Cancer
The purpose of this study is to determine how circulating tumor DNA (ctDNA), a sign of minimal residual disease (MRD), is detectable after surgery in patients with early HR+/HER2- breast cancer that has spread to 1-3 lymph nodes. Researchers aim to understand if ctDNA detection can identify patients at higher …
Investigating Paclitaxel Toxicity in Breast Cancer: the Roles of Physical Activity and Body Composition.
This study looks into how a common breast cancer treatment, paclitaxel, can sometimes cause severe side effects that make it hard for patients to continue treatment. These side effects can significantly affect a patient's quality of life and even impact their recovery and overall health costs. What's interesting about this …
Long Term Followup of Patients Enrolled in MC1137, BEAUTY Study
This study gathers information and samples for further analysis as part of the BEAUTY study. The purpose of the BEAUTY study was to better understand the reasons why or why not breast cancers respond to standard chemotherapy. Collecting samples of blood and tissue and health and treatment information from patients …
Whole Exome Sequencing in Finding Causative Variants in Germline DNA Samples From Patients With Congestive Heart Failure Receiving Therapy for Breast Cancer
This research trial studies whole exome sequencing in finding causative variants in germline deoxyribonucleic acid (DNA) samples from patients with congestive heart failure receiving therapy for breast cancer. Studying samples of germline DNA in the laboratory from patients with congestive heart failure receiving therapy for breast cancer may help doctors …
