NCT07256977

Brief Summary

This study is a multicenter, open-label, non-inferiority, randomized controlled, investigator-initiated clinical trial comparing the efficacy and safety of open radical hysterectomy versus minimally invasive radical hysterectomy using an endoscopic stapler as surgical treatments for early cervical cancer.
