Interventional Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT07600216). This is a study registration, not published results. Lead sponsor: Shanghai East Hospital. Recruitment status: NOT_YET_RECRUITING. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 570 participants (ESTIMATED). Conditions: Prostate Biopsy. Interventions: PROCEDURE: Robotic-Assisted Fusion Biopsy; PROCEDURE: Expert Cognitive Fusion Biopsy. Primary outcome measures: Detection Rate of Clinically Significant Prostate Cancer (csPCa) by Targeted Biopsy , Up to 30 days post-procedure (at the time of final pathology report). Brief summary: The trial aims to find out if using a robotic system to help perform prostate biopsies is better than having a highly experienced doctor perform the biopsy by hand in men with a high Body Mass Index (BMI). While MRI-guided prostate biopsies are highly effective, carrying them out in men with obesity can be physically challenging for doctors. Extra pelvic tissue increases the depth the biopsy needle must travel and makes it difficult to manually hold the ultrasound probe perfectly steady. This physical difficulty might cause doctors to miss some aggressive prostate cancers. This study tests whether a robotic arm-which completely locks the biopsy needle on target and eliminates human hand tremors-can improve cancer detection. The study will enroll up to 570 men with high BMI who have suspicious areas on their prostate MRI. Participants will be randomly assigned to receive either a robotic-assisted biopsy or a standard manual biopsy performed by an expert urologist. To ensure the results are completely unbiased, participants will not know which method is being used on them. They will be placed behind a surgical drape and wear noise-canceling headphones playing music during the procedure to block out the sounds of the robotic motors. The main goal is to see if the robotic method safely and significantly increases the detection rate of clinically significant prostate cancer in this specific group of patients.
