Mutation tracking in circulating tumor DNA predicts relapse in early breast cancer.
(AMER ASSOC ADVANCEMENT SCIENCE, 2015-08-26)
The identification of early-stage breast cancer patients at high risk of relapse would allow tailoring of adjuvant therapy approaches. We assessed whether analysis of circulating tumor DNA (ctDNA) in plasma can be used to ...
Efficient Genotyping of KRAS Mutant Non-Small Cell Lung Cancer Using a Multiplexed Droplet Digital PCR Approach.
(PUBLIC LIBRARY SCIENCE, 2015-09-28)
Droplet digital PCR (ddPCR) can be used to detect low frequency mutations in oncogene-driven lung cancer. The range of KRAS point mutations observed in NSCLC necessitates a multiplex approach to efficient mutation detection ...
Genomic profile of advanced breast cancer in circulating tumour DNA.
(NATURE PORTFOLIO, 2021-04-23)
The genomics of advanced breast cancer (ABC) has been described through tumour tissue biopsy sequencing, although these approaches are limited by geographical and temporal heterogeneity. Here we use plasma circulating ...
Inactivating NF1 Mutations Are Enriched in Advanced Breast Cancer and Contribute to Endocrine Therapy Resistance.
(AMER ASSOC CANCER RESEARCH, 2020-02-01)
PURPOSE: Advanced breast cancer (ABC) has not been subjected to the same degree of molecular scrutiny as early primary cancer. Breast cancer evolves with time and under the selective pressure of treatment, with the potential ...
Comparison of BEAMing and Droplet Digital PCR for Circulating Tumor DNA Analysis.
(AMER ASSOC CLINICAL CHEMISTRY, 2019-11-01)
BACKGROUND: Circulating tumor DNA (ctDNA) assays are increasingly used for clinical decision-making, but it is unknown how well different assays agree. We aimed to assess the agreement in ctDNA mutation calling between ...
Discovery of naturally occurring ESR1 mutations in breast cancer cell lines modelling endocrine resistance.
(NATURE PORTFOLIO, 2017-11-30)
Resistance to endocrine therapy remains a major clinical problem in breast cancer. Genetic studies highlight the potential role of estrogen receptor-α (ESR1) mutations, which show increased prevalence in the metastatic, ...
Molecular characterisation of aromatase inhibitor-resistant advanced breast cancer: the phenotypic effect of ESR1 mutations.
(SPRINGERNATURE, 2019-01-22)
BACKGROUND: Several thousand breast cancer patients develop resistance to aromatase inhibitors (AIs) each year in the UK. Rational treatment requires an improved molecular characterisation of resistant disease. MATERIALS ...
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 ...
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 ...
