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 ...
CCNE1 and PLK1 Mediate Resistance to Palbociclib in HR+/HER2- Metastatic Breast Cancer.
(AMER ASSOC CANCER RESEARCH, 2023-04-14)
PURPOSE: In hormone receptor-positive (HR+)/HER2- metastatic breast cancer (MBC), it is imperative to identify patients who respond poorly to cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) and to discover therapeutic ...
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 ...
Advances in the treatment of advanced oestrogen-receptor-positive breast cancer.
(ELSEVIER SCIENCE INC, 2017-06-17)
Oestrogen-receptor-positive breast cancer is the most common subtype of breast cancer. Endocrine therapies that target the dependence of this subtype on the oestrogen receptor have substantial activity, yet the development ...
Predictors of prolonged benefit from palbociclib plus fulvestrant in women with endocrine-resistant hormone receptor-positive/human epidermal growth factor receptor 2-negative metastatic breast cancer in PALOMA-3.
(ELSEVIER SCI LTD, 2018-11-01)
BACKGROUND: The addition of palbociclib to fulvestrant improved clinical outcomes over placebo-fulvestrant in endocrine-pretreated metastatic breast cancer (MBC) patients in PALOMA-3. Here, we examined factors predictive ...
Assessing HER2 Amplification in Plasma cfDNA.
(HUMANA PRESS INC, 2018-05-02)
Digital PCR (dPCR) is a highly accurate method to determine DNA concentration. In dPCR, DNA is portioned into many discrete single entities, and these are analyzed individually for the presence or absence of a target ...
Overall Survival with Palbociclib and Fulvestrant in Advanced Breast Cancer.
(MASSACHUSETTS MEDICAL SOC, 2018-11-15)
BACKGROUND: The cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitor palbociclib, in combination with fulvestrant therapy, prolongs progression-free survival among patients with hormone-receptor-positive, human epidermal ...
Quality of life with talazoparib after platinum or multiple cytotoxic non-platinum regimens in patients with advanced breast cancer and germline BRCA1/2 mutations: patient-reported outcomes from the ABRAZO phase 2 trial.
(ELSEVIER SCI LTD, 2018-11-01)
BACKGROUND: Talazoparib (1 mg/day) exhibited promising efficacy and safety in patients with advanced breast cancer during ABRAZO (NCT02034916); this study evaluated patient-reported outcomes (PROs). PATIENTS AND METHODS: ...
Long-term Pooled Safety Analysis of Palbociclib in Combination With Endocrine Therapy for HR+/HER2- Advanced Breast Cancer.
(OXFORD UNIV PRESS INC, 2019-04-01)
BACKGROUND: Palbociclib administered with endocrine therapy was tolerable when the overall incidence of toxicities was assessed separately for three PALOMA studies. This study analyzed pooled, longer-term PALOMA safety ...
