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 ...
Abiraterone shows alternate activity in models of endocrine resistant and sensitive disease.
(SPRINGERNATURE, 2018-08-01)
BACKGROUND: Resistance to endocrine therapy remains a major clinical problem in the treatment of oestrogen-receptor positive (ER+) breast cancer. Studies show androgen-receptor (AR) remains present in 80-90% of metastatic ...
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 ...
Low-cost Kinect Version 2 imaging system for breath hold monitoring and gating: Proof of concept study for breast cancer VMAT radiotherapy.
(WILEY, 2018-05-01)
Voluntary inspiration breath hold (VIBH) for left breast cancer patients has been shown to be a safe and effective method of reducing radiation dose to the heart. Currently, VIBH protocol compliance is monitored visually. ...
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 ...
Early ctDNA dynamics as a surrogate for progression-free survival in advanced breast cancer in the BEECH trial.
(ELSEVIER, 2019-06-01)
BACKGROUND: Dynamic changes in circulating tumour DNA (ctDNA) levels may predict long-term outcome. We utilised samples from a phase I/II randomised trial (BEECH) to assess ctDNA dynamics as a surrogate for progression-free ...
Tracking evolution of aromatase inhibitor resistance with circulating tumour DNA analysis in metastatic breast cancer.
(ELSEVIER, 2017-10-04)
BACKGROUND: Selection of resistance mutations may play a major role in the development of endocrine resistance. ESR1 mutations are rare in primary breast cancer but have high prevalence in patients treated with aromatase ...
A RAD51 assay feasible in routine tumor samples calls PARP inhibitor response beyond BRCA mutation.
(WILEY, 2018-12-01)
Poly(ADP-ribose) polymerase (PARP) inhibitors (PARPi) are effective in cancers with defective homologous recombination DNA repair (HRR), including BRCA1/2-related cancers. A test to identify additional HRR-deficient tumors ...
