Plasma ESR1 Mutations and the Treatment of Estrogen Receptor-Positive Advanced Breast Cancer.
(2016-09)
Purpose ESR1 mutations are selected by prior aromatase inhibitor (AI) therapy in advanced breast cancer. We assessed the impact of ESR1 mutations on sensitivity to standard therapies in two phase III randomized trials that ...
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.
(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 ...
Mutation tracking in circulating tumor DNA predicts relapse in early breast cancer.
(AMER ASSOC ADVANCEMENT SCIENCE, 2015-08-26)
The identification of early-stage breast cancer patients at high risk of relapse would allow tailoring of adjuvant therapy approaches. We assessed whether analysis of circulating tumor DNA (ctDNA) in plasma can be used to ...
Efficient Genotyping of KRAS Mutant Non-Small Cell Lung Cancer Using a Multiplexed Droplet Digital PCR Approach.
(PUBLIC LIBRARY SCIENCE, 2015-09-28)
Droplet digital PCR (ddPCR) can be used to detect low frequency mutations in oncogene-driven lung cancer. The range of KRAS point mutations observed in NSCLC necessitates a multiplex approach to efficient mutation detection ...
Analysis of ESR1 mutation in circulating tumor DNA demonstrates evolution during therapy for metastatic breast cancer.
(AMER ASSOC ADVANCEMENT SCIENCE, 2015-11-11)
Acquired ESR1 mutations are a major mechanism of resistance to aromatase inhibitors (AIs). We developed ultra high-sensitivity multiplex digital polymerase chain reaction assays for ESR1 mutations in circulating tumor DNA ...
Triplet Therapy with Palbociclib, Taselisib, and Fulvestrant in PIK3CA-Mutant Breast Cancer and Doublet Palbociclib and Taselisib in Pathway-Mutant Solid Cancers.
(AMER ASSOC CANCER RESEARCH, 2021-01-01)
Cyclin-dependent kinase 4/6 (CDK4/6) and PI3K inhibitors synergize in PIK3CA-mutant ER-positive HER2-negative breast cancer models. We conducted a phase Ib trial investigating the safety and efficacy of doublet CDK4/6 ...
Genomic profile of advanced breast cancer in circulating tumour DNA.
(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 ...
Molecular Residual Disease and Adjuvant Trial Design in Solid Tumors.
(AMER ASSOC CANCER RESEARCH, 2019-10)
Advances in diagnosis and treatment have resulted in a high rate of survival for many patients with early-stage cancers. However, identifying who is at ongoing risk of relapse remains of high priority to direct subsequent ...
PIK3CA mutation enrichment and quantitation from blood and tissue.
(NATURE PORTFOLIO, 2020-10-13)
PIK3CA is one of the two most frequently mutated genes in breast cancers, occurring in 30-40% of cases. Four frequent 'hotspot' PIK3CA mutations (E542K, E545K, H1047R and H1047L) account for 80-90% of all PIK3CA mutations ...
