Treatment and prognosis of leptomeningeal disease secondary to metastatic breast cancer: A single-centre experience.
(CHURCHILL LIVINGSTONE, 2017-12-01)
PURPOSE: Leptomeningeal disease (LMD) is an uncommon complication of advanced breast cancer. The prognosis is poor, and although radiotherapy (RT), systemic and intra-thecal (IT) chemotherapy are accepted treatment modalities, ...
Circulating tumour DNA analysis to direct therapy in advanced breast cancer (plasmaMATCH): a multicentre, multicohort, phase 2a, platform trial.
(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 ...
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 ...
Evaluation of Cancer-Based Criteria for Use in Mainstream BRCA1 and BRCA2 Genetic Testing in Patients With Breast Cancer.
(AMER MEDICAL ASSOC, 2019-05-03)
IMPORTANCE: Increasing BRCA1 and BRCA2 (collectively termed herein as BRCA) gene testing is required to improve cancer management and prevent BRCA-related cancers. OBJECTIVE: To evaluate mainstream genetic testing using ...
Homologous recombination DNA repair deficiency and PARP inhibition activity in primary triple negative breast cancer.
(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 ...
High p16 expression and heterozygous RB1 loss are biomarkers for CDK4/6 inhibitor resistance in ER+ breast cancer.
(NATURE PORTFOLIO, 2022-09-07)
CDK4/6 inhibitors combined with endocrine therapy have demonstrated higher antitumor activity than endocrine therapy alone for the treatment of advanced estrogen receptor-positive breast cancer. Some of these tumors are ...
Early circulating tumor DNA dynamics and clonal selection with palbociclib and fulvestrant for breast cancer.
(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 ...
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 ...
