Analysis of ESR1 mutation in circulating tumor DNA demonstrates evolution during therapy for metastatic breast cancer.
Schiavon, G; Hrebien, S; Garcia-Murillas, I; Cutts, RJ; Pearson, A; et al. (AMER ASSOC ADVANCEMENT SCIENCE, 2015-11-11)Acquired ESR1 mutations are a major mechanism of resistance to aromatase inhibitors (AIs). We developed ultra high-sensitivity multiplex digital polymerase chain reaction assays for ESR1 mutations in circulating tumor DNA ... -
ATR Inhibition Potentiates the Radiation-induced Inflammatory Tumor Microenvironment.
Dillon, MT; Bergerhoff, KF; Pedersen, M; Whittock, H; Crespo-Rodriguez, E; et al. (AMER ASSOC CANCER RESEARCH, 2019-06-01)PURPOSE: ATR inhibitors (ATRi) are in early phase clinical trials and have been shown to sensitize to chemotherapy and radiotherapy preclinically. Limited data have been published about the effect of these drugs on the ... -
ESR1 F404 Mutations and Acquired Resistance to Fulvestrant in ESR1-Mutant Breast Cancer.
Kingston, B; Pearson, A; Herrera-Abreu, MT; Sim, L-X; Cutts, RJ; et al. (AMER ASSOC CANCER RESEARCH, 2024-02-08)UNLABELLED: Fulvestrant is used to treat patients with hormone receptor-positive advanced breast cancer, but acquired resistance is poorly understood. PlasmaMATCH Cohort A (NCT03182634) investigated the activity of fulvestrant ... -
Exceptional Response to AKT Inhibition in Patients With Breast Cancer and Germline PTEN Mutations.
Kingston, B; Bailleux, C; Delaloge, S; Schiavon, G; Scott, V; et al. (American Society of Clinical Oncology (ASCO), 2019-01-01) -
FFPE breast tumour blocks provide reliable sources of both germline and malignant DNA for investigation of genetic determinants of individual tumour responses to treatment.
Wilkins, A; Chauhan, R; Rust, A; Pearson, A; Daley, F; et al. (SPRINGER, 2018-08-01)BACKGROUND: Bio-banked formalin-fixed paraffin-embedded (FFPE) tissues provide an excellent opportunity for translational genomic research. Historically matched blood has not always been collected as a source of germline ... -
High-Level Clonal FGFR Amplification and Response to FGFR Inhibition in a Translational Clinical Trial.
Pearson, A; Smyth, E; Babina, IS; Herrera-Abreu, MT; Tarazona, N; et al. (AMER ASSOC CANCER RESEARCH, 2016-08-01)UNLABELLED: FGFR1 and FGFR2 are amplified in many tumor types, yet what determines response to FGFR inhibition in amplified cancers is unknown. In a translational clinical trial, we show that gastric cancers with high-level ... -
Homologous recombination DNA repair deficiency and PARP inhibition activity in primary triple negative breast cancer.
Chopra, N; Tovey, H; Pearson, A; Cutts, R; Toms, C; et al. (NATURE PORTFOLIO, 2020-05-29)Triple negative breast cancer (TNBC) encompasses molecularly different subgroups, with a subgroup harboring evidence of defective homologous recombination (HR) DNA repair. Here, within a phase 2 window clinical trial, RIO ... -
Inactivating NF1 Mutations Are Enriched in Advanced Breast Cancer and Contribute to Endocrine Therapy Resistance.
Pearson, A; Proszek, P; Pascual, J; Fribbens, C; Shamsher, MK; et al. (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 ... -
Lucitanib for the treatment of HR+ HER2- metastatic breast cancer (MBC) patients (pts): Results from the multicohort phase II FINESSE trial.
Hui, R; Pearson, A; Cortes Castan, J; Campbell, C; Poirot, C; et al. (Elsevier BV, 2019-12-05) -
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 ... -
Olaparib and Ceralasertib (AZD6738) in Patients with Triple-Negative Advanced Breast Cancer: Results from Cohort E of the plasmaMATCH Trial (CRUK/15/010).
Ring, A; Kilburn, LS; Pearson, A; Moretti, L; Afshari-Mehr, A; et al. (AMER ASSOC CANCER RESEARCH, 2023-12-01)PURPOSE: Approximately 10% to 15% of triple-negative breast cancers (TNBC) have deleterious mutations in BRCA1 and BRCA2 and may benefit from PARP inhibitor treatment. PARP inhibitors may also increase exogenous replication ... -
Single-Cell Dynamics Determines Response to CDK4/6 Inhibition in Triple-Negative Breast Cancer.
Asghar, US; Barr, AR; Cutts, R; Beaney, M; Babina, I; et al. (AMER ASSOC CANCER RESEARCH, 2017-09-15)Purpose: Triple-negative breast cancer (TNBC) is a heterogeneous subgroup of breast cancer that is associated with a poor prognosis. We evaluated the activity of CDK4/6 inhibitors across the TNBC subtypes and investigated ... -
