Lack of reliability of nanotechnology in the of free plasma DNA in samples of patients with prostate cancer

---

Abstract
Background:Several studies seek biological markers that give diagnostic and degree of tumor development. The aim of this study was to validate the determination of plasma DNA using nanotechnology (Nanovue™-NV) in samples of 80 patients with prostate cancer.
Methods:Blood samples of 80 patients of the Urology Ambulatory of Faculdade de Medicina do ABC with prostate cancer confirmed by anatomical-pathology criteria were analyzed. DNA extraction was performed using a GFX TM kit (Amersham Pharmacia Biotech, Inc, USA) following the adapted protocol. Plasma was subjected to centrifugation.
Results:There was a big difference between the first and the second value obtained by NanoVue Only two samples had no differences between duplicates. Maximum difference between duplicates was 38μg/mL. Average variation between 51 samples was 10.29μg/mL, although 21 samples had differences above this average. No correlation was observed between pDNA obtained by traditional spectrophotometry and by nanotechnology.
Conclusion:Determination of plasma DNA by nanotechnology was not reproducible.
Keywords:Nanotechnology, DNA, Neoplams, Prostate
