Prostate Cancer and the PSA Biosensor
The PSA Biosensor will help differentiate "organ-confined" from "extra-capsular" Prostate Cancer
Transrectal Ultrasound will be used to guide the PSA Biosensor to the region just outside of the prostate gland.

The PSA biosensor has been developed to give the Urologist an extra diagnostic tool to measure PSA accurately in tissue fluids associated with prostate cancer. The measurements can help optimise staging in the disease.
If the prostate cancer has spread outside of the prostate gland then PSA in tissue fluid surrounding the prostate and in local lymph nodes is present in higher concentrations. If the prostate cancer is restricted to the gland itself, then there will be no elevated PSA in the surrounding area.
Using the InvivoSense PSA Biosensor the Urologist has the ability to take highly accurate and sensitive readings of PSA from tissue fluid samples during surgery or from a biopsy sample related to prostate cancer. The measurements are produced in real time within minutes.
The readings taken by the PSA Biosensor are specific for PSA, providing the Urologist with greater confidence in staging the prostate cancer, essential when considering the next steps for treatment.
