Focal Prostate Imaging With CLE and OCT (FPI)

January 17, 2019 updated by: Dr. T.M. de Reijke, Academisch Medisch Centrum - Universiteit van Amsterdam (AMC-UvA)

In-vivo Focal Prostate Imaging With Confocal Laser Endomicroscopy and Optical Coherence Tomography

The current limitations in prostate cancer diagnostics lead to over- and undertreatment for a significant fraction of patients. Confocal Laser Endomicroscopy (CLE) and Optical Coherence Tomography (OCT) are focal imaging modalities with potential for in-vivo prostate imaging. The investigators anticipate that integrating focal imaging with MRI/TRUS fusion will further improve prostate cancer detection and provides a real-time histopathological threedimensional representation of the tumor lesions.

This is an investigator-initiated, prospective in-vivo safety and feasibility study with transperineal template mapping biopsies (TTMB) and two focal imaging methods, CLE and OCT, in prostate tissue.

Detailed Description

Study design:

This is an investigator-initiated, prospective in-vivo safety and feasibility study with two procedures.

Procedure 1 (AMC):

Patients that are indicated for transperineal template mapping biopsies (TTMB) are included for procedure 1 and will receive transperineal CLE or OCT measurements prior to TTMB. Procedure 1 is to test the technical feasibility and safety of in-vivo focal imaging with CLE and OCT. Only if transperineal CLE or OCT measurements are possible, the investigators proceed with procedure 2.

For procedure 1: 4 patients that are scheduled for TTMB; 2 patients for CLE and 2 patients for OCT.

Procedure 2 (VUmc):

Patients scheduled for a robot-assisted laparoscopic prostatectomy (RALP) will be included in procedure 2 and receive transperineal CLE or OCT measurements prior to their surgery. Results will be correlated with histology by correlating biopsies during the TTMB procedure or with RALP the measurement trajectory will be marked. After the RALP, the prostate will be cut exactly through the measurement trajectory for whole mount coupes. In high-risk of high-intermediate-risk patients receiving an extended pelvic lymph node dissection with the RALP, ex-vivo CLE measurements will be performed.

For procedure 2: 10 patients that are scheduled for RALP; 5 patients for CLE and 5 patients for OCT. Intervention: Transperineal CLE or OCT measurements will be performed directly prior to the TTMB or RALP. The CLE and OCT probes are inserted by a needle with the same diameter as a biopsy gun. In the case of RALP, measurement trajectories will be marked for histopathology correlation.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
