Modeling Therapy Resistance in BRCA1/2-Mutant Cancers.
(AMER ASSOC CANCER RESEARCH, 2017-09-01)
Although PARP inhibitors target BRCA1- or BRCA2-mutant tumor cells, drug resistance is a problem. PARP inhibitor resistance is sometimes associated with the presence of secondary or "revertant" mutations in BRCA1 or BRCA2 ...
Reproducibility of Digital PCR Assays for Circulating Tumor DNA Analysis in Advanced Breast Cancer.
(PUBLIC LIBRARY SCIENCE, 2016-10-19)
Circulating tumor DNA (ctDNA) analysis has the potential to allow non-invasive analysis of tumor mutations in advanced cancer. In this study we assessed the reproducibility of digital PCR (dPCR) assays of circulating tumor ...
Assessing HER2 Amplification in Plasma cfDNA.
(HUMANA PRESS INC, 2018-05-02)
Digital PCR (dPCR) is a highly accurate method to determine DNA concentration. In dPCR, DNA is portioned into many discrete single entities, and these are analyzed individually for the presence or absence of a target ...
Circulating tumour DNA is a potential biomarker for disease progression and response to targeted therapy in advanced thyroid cancer.
(ELSEVIER SCI LTD, 2018-11-01)
BACKGROUND: Conventional biomarkers in thyroid cancer are not disease specific and fluctuate in advanced disease, making interpretation difficult. Circulating tumour DNA (ctDNA) has been shown to be a useful biomarker in ...
The Spatiotemporal Evolution of Lymph Node Spread in Early Breast Cancer.
(SPRINGER, 2018-02-01)
Purpose: The most significant prognostic factor in early breast cancer is lymph node involvement. This stage between localized and systemic disease is key to understanding breast cancer progression; however, our knowledge ...
The Genetic Landscape and Clonal Evolution of Breast Cancer Resistance to Palbociclib plus Fulvestrant in the PALOMA-3 Trial.
(AMER ASSOC CANCER RESEARCH, 2018-11-01)
CDK4/6 inhibition with endocrine therapy is now a standard of care for advanced estrogen receptor-positive breast cancer. Mechanisms of CDK4/6 inhibitor resistance have been described preclinically, with limited evidence ...
Baseline Mutations and ctDNA Dynamics as Prognostic and Predictive Factors in ER-Positive/HER2-Negative Metastatic Breast Cancer Patients.
(AMER ASSOC CANCER RESEARCH, 2023-10-13)
PURPOSE: Prognostic and predictive biomarkers to cyclin-dependent kinases 4 and 6 inhibitors are lacking. Circulating tumor DNA (ctDNA) can be used to profile these patients and dynamic changes in ctDNA could be an early ...
Comparison of Circulating Tumor DNA Assays for Molecular Residual Disease Detection in Early-Stage Triple-Negative Breast Cancer.
(AMER ASSOC CANCER RESEARCH, 2024-02-16)
PURPOSE: Detection of circulating tumor DNA (ctDNA) in patients who have completed treatment for early-stage breast cancer is associated with a high risk of relapse, yet the optimal assay for ctDNA detection is unknown. ...
Results of the c-TRAK TN trial: a clinical trial utilising ctDNA mutation tracking to detect molecular residual disease and trigger intervention in patients with moderate- and high-risk early-stage triple-negative breast cancer.
(ELSEVIER, 2022-11-21)
BACKGROUND: Post-treatment detection of circulating tumour DNA (ctDNA) in early-stage triple-negative breast cancer (TNBC) patients predicts high risk of relapse. c-TRAK TN assessed the utility of prospective ctDNA ...
