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.

Cancer Prostate Other: Fluorescence assessment

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Assessment of a New Fluorescence Imaging Technique Using Biopsies From Prostate Resection

Primary Outcome Measures:

Secondary Outcome Measures:

Estimated Enrollment: 12
Anticipated Study Start Date: May 2017
Estimated Study Completion Date: May 2018
Estimated Primary Completion Date: March 2018 (Final data collection date for primary outcome measure)
Experimental: fluorescence assessment

Medical device: Use of the FEMTO-ST institute medical device to detect prostatic and non prostatic tissue.

Other: Fluorescence assessment

All subjects of the study are going to have a radical prostatectomy. The FEMTO-ST medical device is used on 3 fresh biopsies (2 healthy and 1 malignant) which will be preleved from the resected prostate in order to determine the prostatic or non-prostatic nature of tissue.

For this protocol, 12 patients will be included.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample

Patient with indication for radical prostatectomy

Inclusion Criteria:

Exclusion Criteria:

  • patient with contraindication to radical prostatectomy
  • patient with remedial prostatectomy
  • patient with normal preoperative MRI or with absence of tumoral area
  • patient with history of hormonal therapy
  • person deprived of freedom by judicial or administrative decision
  • person under legal protection
  • person hospitalized for psychiatric care.
