Filter by:Triple-negative breast cancer (TNBC) is biologically aggressive and has limited systemic treatment options, often compounded by treatment resistance. Cell state transitions, e.g. epithelial-to-mesenchymal transition (EMT) govern cancer cell behaviour. The investigators hypothesize that by inducing change in cell state change, TNBC cells that have manifested taxane-resistance will be more sensitized to subsequent chemotherapy.
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, including thymidine kinase1 activity, gene expression signatures and circulating tumor DNA.
Sonazoid as a new generation of ultrasound contrast agent.This study based on the features of Sonazoid specific angiography and high mechanical index,the role of Sonazoid in the differential diagnosis of breast benign and malignant tumors was explored.
Detection of multifocal, multicentric breast cancer in patients with breast cancer affects surgical decision. Histology-proven additional cancer foci have been reported to be detected in 21.0% to 63.0% of affected breasts in women thought to have localized cancer based on clinical assessment and mammography. Dynamic contrast-enhanced (DCE) MRI is often applied in the preoperative local staging of breast cancer due to its high sensitivity and identifies additional foci that would have otherwise remained undetected on clinical assessment and conventional imaging (mammography and ultrasonography). However, DCE MRI is limited in use due to its low specificity with high false positive rate, causing unnecessary and incorrect conversion to more extensive surgery. Diffusion-weighted MRI (DWI) is a fast, functional MRI technique that measures the movement of water molecules to create tissue contrast without the need for contrast injection. Breast malignancies exhibit hindered diffusion and appear hyperintense on DWI with low apparent diffusion coefficient (ADC) values compared to normal surrounding tissue or benign tumors. Multiple studies including one prospective multi-center trial showed that DWI can reduce unnecessary benign biopsies of suspicious mammographic or DCE MRI-detected lesions and DWI is now considered as an important part of multi-parametric breast MRI protocols. However, little is known about the role of DWI as an adjunct to DCE MRI in the local staging of women with breast cancer. The purpose of our study is to determine whether DWI improves the performance of preoperative DCE MRI in the evaluation of additional lesions in breast cancer patients.
The purpose of the study is to evaluate which is more effective resistance or aerobic exercises on cancer related fatigue and immunity in breast cancer patients undergoing adjuvant chemotherapy.
The purpose of the study is to evaluate the effectiveness of an online psychosocial self-help program for Chinese immigrant women with breast cancer, by comparing Chinese immigrant women who receive the online psychosocial program and those who do not receive the program. The investigators want to understand if this online psychosocial program is effective in helping Chinese immigrant women to feel more supported, understand that the distress is normal, engage in self-care activities, become aware of the community resources, feel more confident about returning to a normal life, and feel less distress overall as they return to life after treatment. This information will help us to better understand these Chinese immigrant women's needs and concerns and plan future growth of the program to meet their personal, cultural, and language needs.
The main objectives of this study are to describe patient characteristics, treatment patterns and clinical outcomes of patients receiving palbociclib in Swedish clinical practice.
polymorphisms of drug transporter genes may influence of Doxorubicin-Cyclophosphamide toxicity in breast cancer patients. the investigators want to evaluate the association between associations between genetic polymorphisms of ABCB1,SLC22A16 Genes and Toxicity of Doxorubicin and Cyclophosphamide Chemotherapy in Breast Cancer Patients treated by Doxorubicin-Cyclophosphamide regimen therapy
This is a monocentric cohort study, prospective and interventional with minimal risks and constraints for advanced breast cancer. The planned interventions are collection of biological samples at different times. The study will aim to do a descriptive analysis of omics profiles evolution (tumor, volatile organic components) over time, before and after disease progression under Palbociclib treatment with a clinical-biological database.
The aim of this study is to determinate if therapeutic exercise with blood flow restriction (BFR) during neoadjuvant chemotherapy potentialy neurotoxic could prevent the onset of chemotherapy induced peripheral neuropathy (CIPN) comparing to usual care.
