The paper was based on the study of 20-patients whose prostate cancer had been diagnosed as recurring the pelvic region up to 3-times. Using prostate-specific membrane (PMSA)-targeted radio guidance, which has previously found to be beneficial during open procedures, the team used a miniaturized, minimally-invasive drop-in gamma probe robotically. An injectable radioactive tracer was used in conjunction with the gamma probe. The Authors state that “This procedure holds promise for improving the intraoperative identification and removal of prostate cancer lesions.”
