Assessment of a New Fluorescence Imaging Technique Using Biopsies From Prostate Resection

Terminated

• Conditions: Cancer Prostate

• Registration Number: NCT03157856
• Lead Sponsor: University Hospital, Grenoble

Brief Summary

In this study, we aim to evaluate the feasibility of anti-PSMA labelling to detect post-operative prostatic tissues by two ex vivo fluorescence techniques. We will evaluate the feasibility and detection of anti-PSMA labelling by:

1. / the FEMTO-ST institute medical device,

2. / the confocal microscope that will be used to measure fluorescence spectra of biological samples.

Detailed Description

For this protocol, 12 patients will be included.

Primary Outcome Measures

Name	Time	Method
Comparison of the fluorescence obtained using the FEMTO-ST device and the confocal microscope of anti-PSMA marked fresh prostate biopsies, for prostatic and non-prostatic tissue, as identified by anatomo-pathology (gold standard).	14 months	Fluorescence measurements obtained using the FEMTO-ST medical device and the confocal microscope.

Secondary Outcome Measures

Name	Time	Method
Comparison of the fluorescence obtained using the FEMTO-ST device and the confocal microscope of anti-PSMA marked fresh prostate biopsies, for cancerous and non-cancerous tissue, as identified by anatomo-pathology (gold standard).	14 months	Fluorescence measurements obtained using the FEMTO-ST medical device and the confocal microscope.
