2019 FEB 18 (NewsRx) -- By a News Reporter-Staff News Editor at Cancer Daily -- Current study results on Oncology - Prostate Cancer have been published. According to news reporting from Ann Arbor, Michigan, by NewsRx journalists, research stated, “Rates of progression and treatment response in advanced prostate cancer are highly variable, necessitating non-invasive methods to assess the molecular characteristics of these tumors in real time. The unique potential of circulating tumor cells (CTCs) to serve as a clinically useful liquid biomarker is due to their ability to inform via both enumeration and RNA expression.”

Financial supporters for this research include National Institutes of Health, U.S. Department of Defense, Prostate Cancer Foundation, A. Alfred Taubman Medical Research Institute, National Science Foundation.

The news correspondents obtained a quote from the research from the University of Michigan, “A microfluidic graphene oxide-based device (GO Chip) is used to isolate CTCs and CTC clusters from the whole blood of 41 men with metastatic castration-resistant prostate cancer. Additionally, the expression of 96 genes of interest is determined by RT-qPCR. Multivariate analyses are conducted to determine the genes most closely associated with overall survival, PSA progression, and radioclinical progression.”

According to the news reporters, the research concluded: “A preliminary signature, comprising high expression of stemness genes and low expression of epithelial and mesenchymal genes, potentially implicates an undifferentiated CTC phenotype as a marker of poor prognosis in this setting.”
