简要总结
The aim of this study is divided in 4 different steps:
- the first step has two different purpose: assess the impact of the storage medium of fresh prostatic chips on fluorescence signal and adjust the entire chain (immunolabelling,counter-stain and imaging),
- the second step is the adaptation of immunolabelling protocol on histopathology slides, using fresh prostatic tissue,
- the third step is to validate the use of:
- the medical device created by the FEMTO-ST institute use for the detection of fluorescence signal on fresh tissue,
- the Light-CT scanner use for tissue structural observation.
- the four step is to check the preservation of morphological structure of tissue under the effect of laser excitation from the medical device.

研究组 & 干预措施
Fluorescence assesment
All patients undergo a transurethral resection.
There are four different steps in the study:
- the first step: fresh prostatic tissue of 30 subjects will be use to asses the fluorescence signal and the entire chain,
- the second step: fresh prostatic tissue of 10 subjects will be used to asses the immunolabelling protocol,
- the third step: fresh prostatic tissue of 20 subjects will be used to asses the use of the FEMTO-ST institute medical device,
- the four step: the fresh prostatic tissue from the 10 subjects of the second step will be evaluated to verify the preservation of morphological structure with the use of the Light-CT scanner.
干预措施: Trans-urethral resection (Procedure)
