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 ...
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 ...
Modeling Therapy Resistance in BRCA1/2-Mutant Cancers.
(AMER ASSOC CANCER RESEARCH, 2017-09-01)
Although PARP inhibitors target BRCA1- or BRCA2-mutant tumor cells, drug resistance is a problem. PARP inhibitor resistance is sometimes associated with the presence of secondary or "revertant" mutations in BRCA1 or BRCA2 ...
Reproducibility of Digital PCR Assays for Circulating Tumor DNA Analysis in Advanced Breast Cancer.
(PUBLIC LIBRARY SCIENCE, 2016-10-19)
Circulating tumor DNA (ctDNA) analysis has the potential to allow non-invasive analysis of tumor mutations in advanced cancer. In this study we assessed the reproducibility of digital PCR (dPCR) assays of circulating tumor ...
Diverse BRCA1 and BRCA2 Reversion Mutations in Circulating Cell-Free DNA of Therapy-Resistant Breast or Ovarian Cancer.
(AMER ASSOC CANCER RESEARCH, 2017-11-01)
Purpose: Resistance to platinum-based chemotherapy or PARP inhibition in germline BRCA1 or BRCA2 mutation carriers may occur through somatic reversion mutations or intragenic deletions that restore BRCA1 or BRCA2 function. ...
Gatekeeper Mutations and Intratumoral Heterogeneity in FGFR2-Translocated Cholangiocarcinoma.
(AMER ASSOC CANCER RESEARCH, 2017-03-01)
<b/>FGFR2 genetic translocations are frequent in cholangiocarcinoma, yet despite initial sensitivity to FGFR inhibitors in clinic, patients quickly become resistant to targeted therapies. The work published by Goyal and ...
Targeting PIK3CA-mutant advanced breast cancer in the clinical setting.
(ELSEVIER SCIENCE INC, 2017-07-01)
The Genetic Landscape and Clonal Evolution of Breast Cancer Resistance to Palbociclib plus Fulvestrant in the PALOMA-3 Trial.
(AMER ASSOC CANCER RESEARCH, 2018-11-01)
CDK4/6 inhibition with endocrine therapy is now a standard of care for advanced estrogen receptor-positive breast cancer. Mechanisms of CDK4/6 inhibitor resistance have been described preclinically, with limited evidence ...
ESMO recommendations on the use of circulating tumour DNA assays for patients with cancer: a report from the ESMO Precision Medicine Working Group.
(ELSEVIER, 2022-08-01)
Circulating tumour DNA (ctDNA) assays conducted on plasma are rapidly developing a strong evidence base for use in patients with cancer. The European Society for Medical Oncology convened an expert working group to review ...
