Second-Generation HSP90 Inhibitor Onalespib Blocks mRNA Splicing of Androgen Receptor Variant 7 in Prostate Cancer Cells.
(AMER ASSOC CANCER RESEARCH, 2016-05-01)
Resistance to available hormone therapies in prostate cancer has been associated with alternative splicing of androgen receptor (AR) and specifically, the expression of truncated and constitutively active AR variant 7 ...
Decline in Circulating Tumor Cell Count and Treatment Outcome in Advanced Prostate Cancer.
(ELSEVIER SCIENCE BV, 2016-12-01)
BACKGROUND: Treatment response biomarkers are urgently needed for castration-resistant prostate cancer (CRPC). Baseline and post-treatment circulating tumor cell (CTC) counts of ≥5 cells/7.5ml are associated with poor CRPC ...
DNA-Repair Defects and Olaparib in Metastatic Prostate Cancer.
(MASSACHUSETTS MEDICAL SOC, 2015-10-29)
BACKGROUND: Prostate cancer is a heterogeneous disease, but current treatments are not based on molecular stratification. We hypothesized that metastatic, castration-resistant prostate cancers with DNA-repair defects would ...
Clinical Utility of Circulating Tumour Cell Androgen Receptor Splice Variant-7 Status in Metastatic Castration-resistant Prostate Cancer.
(ELSEVIER, 2019-11-01)
BACKGROUND: Detection of androgen receptor splice variant-7 (AR-V7) mRNA in circulating tumour cells (CTCs) is associated with worse outcome in metastatic castration-resistant prostate cancer (mCRPC). However, studies ...
Immunogenomic analyses associate immunological alterations with mismatch repair defects in prostate cancer.
(AMER SOC CLINICAL INVESTIGATION INC, 2018-10-01)
BACKGROUND: Understanding the integrated immunogenomic landscape of advanced prostate cancer (APC) could impact stratified treatment selection. METHODS: Defective mismatch repair (dMMR) status was determined by either loss ...
SPOP-Mutated/CHD1-Deleted Lethal Prostate Cancer and Abiraterone Sensitivity.
(AMER ASSOC CANCER RESEARCH, 2018-11-15)
Purpose: CHD1 deletions and SPOP mutations frequently cooccur in prostate cancer with lower frequencies reported in castration-resistant prostate cancer (CRPC). We monitored CHD1 expression during disease progression and ...
Circulating tumour cell increase as a biomarker of disease progression in metastatic castration-resistant prostate cancer patients with low baseline CTC counts.
(ELSEVIER, 2018-07-01)
BACKGROUND: The development of treatment response and surrogate biomarkers for advanced prostate cancer care is an unmet clinical need. Patients with baseline circulating tumour cell (BLCTCs) counts <5/7.5 mL represent a ...
Single-Cell Analyses of Prostate Cancer Liquid Biopsies Acquired by Apheresis.
(AMER ASSOC CANCER RESEARCH, 2018-11-15)
Purpose: Circulating tumor cells (CTCs) have clinical relevance, but their study has been limited by their low frequency.Experimental Design: We evaluated liquid biopsies by apheresis to increase CTC yield from patients ...
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, ...
Circulating Cell-Free DNA to Guide Prostate Cancer Treatment with PARP Inhibition.
(AMER ASSOC CANCER RESEARCH, 2017-09-01)
Biomarkers for more precise patient care are needed in metastatic prostate cancer. We have reported a phase II trial (TOPARP-A) of the PARP inhibitor olaparib in metastatic prostate cancer, demonstrating antitumor activity ...
