Reduced genomic tumor heterogeneity after neoadjuvant chemotherapy is related to favorable outcome in patients with esophageal adenocarcinoma.
(2016-07)
Neoadjuvant chemo(radio)therapy followed by surgery is the standard of care for patients with locally advanced resectable esophageal adenocarcinoma (EAC). There is increasing evidence that drug resistance might be related ...
Characterization of the genomic features and expressed fusion genes in micropapillary carcinomas of the breast.
(WILEY, 2014-04-01)
Micropapillary carcinoma (MPC) is a rare histological special type of breast cancer, characterized by an aggressive clinical behaviour and a pattern of copy number aberrations (CNAs) distinct from that of grade- and oestrogen ...
Meta-analysis of tumor- and T cell-intrinsic mechanisms of sensitization to checkpoint inhibition.
(CELL PRESS, 2021-02-04)
Checkpoint inhibitors (CPIs) augment adaptive immunity. Systematic pan-tumor analyses may reveal the relative importance of tumor-cell-intrinsic and microenvironmental features underpinning CPI sensitization. Here, we ...
A streamlined workflow for single-cells genome-wide copy-number profiling by low-pass sequencing of LM-PCR whole-genome amplification products.
(PUBLIC LIBRARY SCIENCE, 2018-03-01)
Chromosomal instability and associated chromosomal aberrations are hallmarks of cancer and play a critical role in disease progression and development of resistance to drugs. Single-cell genome analysis has gained interest ...
Ultra-Sensitive Mutation Detection and Genome-Wide DNA Copy Number Reconstruction by Error-Corrected Circulating Tumor DNA Sequencing.
(OXFORD UNIV PRESS INC, 2018-08-27)
BACKGROUND: Circulating free DNA sequencing (cfDNA-Seq) can portray cancer genome landscapes, but highly sensitive and specific technologies are necessary to accurately detect mutations with often low variant frequencies. ...
PIM1 kinase regulates cell death, tumor growth and chemotherapy response in triple-negative breast cancer.
(NATURE PUBLISHING GROUP, 2016-11-01)
Triple-negative breast cancers (TNBCs) have poor prognosis and lack targeted therapies. Here we identified increased copy number and expression of the PIM1 proto-oncogene in genomic data sets of patients with TNBC. TNBC ...
RB1 Heterogeneity in Advanced Metastatic Castration-Resistant Prostate Cancer.
(AMER ASSOC CANCER RESEARCH, 2019-01-15)
PURPOSE: Metastatic castration-resistant prostate cancer (mCRPC) is a lethal but clinically heterogeneous disease, with patients having variable benefit from endocrine and cytotoxic treatments. Intrapatient genomic ...
FFPE breast tumour blocks provide reliable sources of both germline and malignant DNA for investigation of genetic determinants of individual tumour responses to treatment.
(SPRINGER, 2018-08-01)
BACKGROUND: Bio-banked formalin-fixed paraffin-embedded (FFPE) tissues provide an excellent opportunity for translational genomic research. Historically matched blood has not always been collected as a source of germline ...
Gene Copy Number Estimation from Targeted Next-Generation Sequencing of Prostate Cancer Biopsies: Analytic Validation and Clinical Qualification.
(AMER ASSOC CANCER RESEARCH, 2017-10-15)
Purpose: Precise detection of copy number aberrations (CNA) from tumor biopsies is critically important to the treatment of metastatic prostate cancer. The use of targeted panel next-generation sequencing (NGS) is inexpensive, ...
Selection of metastasis competent subclones in the tumour interior.
(NATURE PORTFOLIO, 2021-05-17)
The genetic evolutionary features of solid tumour growth are becoming increasingly well described, but the spatial and physical nature of subclonal growth remains unclear. Here, we utilize 102 macroscopic whole-tumour ...
