Extraperitoneal SINgle-port rObotic-assisted Radical Prostatectomy (RARP) Versus Transperitoneal Multi-port RARP in the Treatment Of Prostate Cancer (SINO-TOP)

This study is comparing two surgical approaches for robotic-assisted radical prostatectomy — the complete surgical removal of the prostate — in men with early-stage prostate cancer. One approach goes through the space outside the abdominal cavity using a single port, and the other goes through the abdominal cavity using multiple ports. Researchers want to compare recovery, complications, and sexual function outcomes. **You may be eligible if...** - You are a man between 18 and 75 years old - You have been diagnosed with early-stage (organ-confined) prostate cancer - Your PSA level is below 20 ng/mL and your Gleason score is less than 8 - You had a biopsy within the past 6 months confirming the diagnosis - You had normal sexual function before your diagnosis and wish to preserve it - You can read and complete questionnaires in Chinese **You may NOT be eligible if...** - Your cancer is high-risk or has spread outside the prostate - You have had prior prostate or abdominal surgery or pelvic radiation - Your general health status is poor (ECOG greater than 1) - You have another active cancer Talk to your doctor to see if this trial is right for you.
