Early circulating tumor DNA dynamics and clonal selection with palbociclib and fulvestrant for breast cancer.
O'Leary, B; Hrebien, S; Morden, JP; Beaney, M; Fribbens, C; et al. (NATURE PORTFOLIO, 2018-03-01)CDK4/6 inhibition substantially improves progression-free survival (PFS) for women with advanced estrogen receptor-positive breast cancer, although there are no predictive biomarkers. Early changes in circulating tumor DNA ... -
Efficient Genotyping of KRAS Mutant Non-Small Cell Lung Cancer Using a Multiplexed Droplet Digital PCR Approach.
Pender, A; Garcia-Murillas, I; Rana, S; Cutts, RJ; Kelly, G; et al. (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 ... -
ESR1 Mutations and Overall Survival on Fulvestrant versus Exemestane in Advanced Hormone Receptor-Positive Breast Cancer: A Combined Analysis of the Phase III SoFEA and EFECT Trials.
Turner, NC; Swift, C; Kilburn, L; Fribbens, C; Beaney, M; et al. (AMER ASSOC CANCER RESEARCH, 2020-10-01)PURPOSE: ESR1 mutations are acquired frequently in hormone receptor-positive metastatic breast cancer after prior aromatase inhibitors. We assessed the clinical utility of baseline ESR1 circulating tumor DNA (ctDNA) analysis ... -
Genomic profile of advanced breast cancer in circulating tumour DNA.
Kingston, B; Cutts, RJ; Bye, H; Beaney, M; Walsh-Crestani, G; et al. (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 ... -
Molecular characterisation of aromatase inhibitor-resistant advanced breast cancer: the phenotypic effect of ESR1 mutations.
Lopez-Knowles, E; Pearson, A; Schuster, G; Gellert, P; Ribas, R; et al. (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 ... -
Mutation tracking in circulating tumor DNA predicts relapse in early breast cancer.
Garcia-Murillas, I; Schiavon, G; Weigelt, B; Ng, C; Hrebien, S; et al. (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 ... -
Plasma ESR1 Mutations and the Treatment of Estrogen Receptor-Positive Advanced Breast Cancer.
Fribbens, C; O'Leary, B; Kilburn, L; Hrebien, S; Garcia-Murillas, I; et al. (2016-09)Purpose ESR1 mutations are selected by prior aromatase inhibitor (AI) therapy in advanced breast cancer. We assessed the impact of ESR1 mutations on sensitivity to standard therapies in two phase III randomized trials that ... -
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.
Turner, NC; Swift, C; Jenkins, B; Kilburn, L; Coakley, M; et al. (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 ... -
Triplet Therapy with Palbociclib, Taselisib, and Fulvestrant in PIK3CA-Mutant Breast Cancer and Doublet Palbociclib and Taselisib in Pathway-Mutant Solid Cancers.
Pascual, J; Lim, JSJ; Macpherson, IR; Armstrong, AC; Ring, A; et al. (AMER ASSOC CANCER RESEARCH, 2021-01-01)Cyclin-dependent kinase 4/6 (CDK4/6) and PI3K inhibitors synergize in PIK3CA-mutant ER-positive HER2-negative breast cancer models. We conducted a phase Ib trial investigating the safety and efficacy of doublet CDK4/6 ...
