Abiraterone in patients with recurrent epithelial ovarian cancer: principal results of the phase II Cancer of the Ovary Abiraterone (CORAL) trial (CRUK - A16037).
Banerjee, S; Tovey, H; Bowen, R; Folkerd, E; Kilburn, L; et al. (SAGE PUBLICATIONS LTD, 2020-12-01)BACKGROUND: Recurrent epithelial ovarian cancer (EOC) remains difficult to treat, with an urgent need for more therapy options. Androgens bind to the androgen receptor (AR), commonly expressed in EOC. CYP17 inhibitor ... -
Carboplatin in BRCA1/2-mutated and triple-negative breast cancer BRCAness subgroups: the TNT Trial.
Tutt, A; Tovey, H; Cheang, MCU; Kernaghan, S; Kilburn, L; et al. (NATURE PUBLISHING GROUP, 2018-04-30)Germline mutations in BRCA1/2 predispose individuals to breast cancer (termed germline-mutated BRCA1/2 breast cancer, gBRCA-BC) by impairing homologous recombination (HR) and causing genomic instability. HR also repairs ... -
Circulating tumour DNA analysis to direct therapy in advanced breast cancer (plasmaMATCH): a multicentre, multicohort, phase 2a, platform trial.
Turner, NC; Kingston, B; Kilburn, LS; Kernaghan, S; Wardley, AM; et al. (ELSEVIER SCIENCE INC, 2020-10-01)BACKGROUND: Circulating tumour DNA (ctDNA) testing might provide a current assessment of the genomic profile of advanced cancer, without the need to repeat tumour biopsy. We aimed to assess the accuracy of ctDNA testing ... -
Comparison of Circulating Tumor DNA Assays for Molecular Residual Disease Detection in Early-Stage Triple-Negative Breast Cancer.
Coakley, M; Villacampa, G; Sritharan, P; Swift, C; Dunne, K; et al. (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. ... -
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 ... -
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 ... -
HER2-enriched subtype and novel molecular subgroups drive aromatase inhibitor resistance and an increased risk of relapse in early ER+/HER2+ breast cancer.
Bergamino, MA; López-Knowles, E; Morani, G; Tovey, H; Kilburn, L; et al. (ELSEVIER, 2022-08-16)BACKGROUND: Oestrogen receptor positive/ human epidermal growth factor receptor positive (ER+/HER2+) breast cancers (BCs) are less responsive to endocrine therapy than ER+/HER2- tumours. Mechanisms underpinning the ... -
Increasing the dose intensity of chemotherapy by more frequent administration or sequential scheduling: a patient-level meta-analysis of 37 298 women with early breast cancer in 26 randomised trials.
Early Breast Cancer Trialists' Collaborative Group (EBCTCG), (ELSEVIER SCIENCE INC, 2019-04-06)BACKGROUND: Increasing the dose intensity of cytotoxic therapy by shortening the intervals between cycles, or by giving individual drugs sequentially at full dose rather than in lower-dose concurrent treatment schedules, ... -
Long-term outcome and prognostic value of Ki67 after perioperative endocrine therapy in postmenopausal women with hormone-sensitive early breast cancer (POETIC): an open-label, multicentre, parallel-group, randomised, phase 3 trial.
Smith, I; Robertson, J; Kilburn, L; Wilcox, M; Evans, A; et al. (ELSEVIER SCIENCE INC, 2020-11-01)BACKGROUND: Preoperative and perioperative aromatase inhibitor (POAI) therapy has the potential to improve outcomes in women with operable oestrogen receptor-positive primary breast cancer. It has also been suggested that ... -
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 ... -
Operational complexity versus design efficiency: challenges of implementing a phase IIa multiple parallel cohort targeted treatment platform trial in advanced breast cancer.
Snowdon, C; Kernaghan, S; Moretti, L; Turner, NC; Ring, A; et al. (BMC, 2022-05-07)BACKGROUND: Platform trial designs are used increasingly in cancer clinical research and are considered an efficient model for evaluating multiple compounds within a single disease or disease subtype. However, these trial ... -
