Trial Identification

Brief Title: Focal Prostate Imaging With CLE and OCT

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

Study ID: NCT03253458

Conditions

Prostate Cancer

Study Description

Brief Summary: 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. Intervention: Transperineal CLE or OCT measurements will be performed directly prior to the TTMB or RALP.
