Evaluation of Prognostic Factors: From Breast Cancer to Bone Metastases
Bone metastases represent a frequent complication of some solid tumours, particularly prostate, breast and lung carcinomas. Bone metastases can cause pain and give rise to the so-called "Skeletal-related Events" (SRE) such as pathological fractures and nerve compression. Despite advances in cancer treatment in general, treatment options for bone metastases remain …
Study of Screening Brain MRIs in Stage IV Breast Cancer
The study is a single arm, nonrandomized phase II prospective study, with the goal of investigating the role of screening brain MRIs in neurologically asymptomatic patients with metastatic breast cancer.
Drug Sensitivity of Hydrothorax and Ascite Organoids from Breast Cancer
Malignant hydrothorax and ascitic fluid in advanced breast cancer often arise from metastasis to the lungs, pleura, or liver. Patients with this condition experience rapid disease progression and multidrug resistance, facing limited treatment options. Clinical guidelines offer various therapies based on molecular subtypes; however, their effectiveness can be hindered by …
Hypofractionated Radiotherapy With Concomitant Tumor Bed Boost for Breast Cancer
Hypofractionated breast radiotherapy with concomitant tumor bed boost for early breast cancer or ductal breast carcinoma in situ after partial mastectomy
Body Image and Physical Activity of Women with Breast Cancer
The goal of this self-initiated questionnaire-based follow-up clinical trial is to map the body image and physical activity of Hungarian women treated for breast cancer. The main questions it aims to answer are: How body image changes during different treatments among women treated for breast cancer? How is physical activity …
To Identify Primary Resistance to CDK4/6 Inhibitors in Breast Cancer
This is a multi-center biomarkers study aiming to prospectively collect biological samples from patients with ER+ and HER2-negative metastatic breast cancer, who are candidate to first-line treatment with an aromatase inhibitor and a CDK4/6 inhibitor as per standard clinical practice. Blood and tissue samples will be collected for biomarker analysis, …
A Composite Assay for HER2-positive Early-stage Breast Cancer Management
The goal of this observational study is to assess the prognostic value of a genomic classifier (S18) and its refined version (S*) in women with early-stage HER2-positive breast cancer. The study aims to determine whether these tools can predict event-free (EFS) and disease-free survival (DFS) in patients treated with neoadjuvant …
GzmB-PET/CT to Evaluate Neoadjuvant Therapy Efficacy in Breast Cancer
To explore the efficacy of 68Ga-GZMB PET/CT in assessing the response to neoadjuvant therapy for breast cancer, and to investigate the optimal SUVmax threshold of 68Ga-GZMB PET/CT for predicting pathological complete response (pCR), aiming to provide a new and effective means for accurately and non-invasively evaluating the efficacy of neoadjuvant …
Application of CfDNA Methylation Detection in Auxiliary Diagnosis of Breast Cancer
The purpose of this study is to construct an auxiliary diagnostic model for breast cancer by methylation markers. The study will collect blood and tissue samples from participants with breast cancer and benign disease for whole-genome methylation sequencing. It will screen methylation markers and develop a methylation auxiliary diagnosis model …
21-gene in Elder Breast Cancer Patients With Lymph Node Metastasis
This study is a single-center, bidirectional cohort study. It aims to include 35 elderly (≥65 years old) Luminal A type breast cancer patients with axillary lymph node metastasis after surgery as the research subjects. After signing the informed consent, the patients who meet the inclusion criteria will have their various …
