| Outline of Final Research Achievements |
The key to determining the guideline for the continuation of monitoring of prostate cancer surveillance patients or the transition to curative treatment is the progression of prostate cancer lesions diagnosed by needle biopsy at the time of decision on surveillance therapy. We have developed an imaging artifact-less maker that can recognize the three-dimensional position inside the prostate. A non-clinical experiment of the developed marker was conducted for the purpose of clinical application of this marker to humans. Specifically, we conducted animal experiments using phantoms and dogs, and conducted image comparison tests with the market metal marker using multiparametric MRI and transrectal ultrasonic tomography, demonstrating the superiority of the development marker. For the purpose of clinical use (manufacturing) in surveillance therapy, PMDA provided face-to-face advice and established the outline of non-clinical studies required in the future.
