The main hypothesis of this study is that laparoscopic radical hysterectomy incorporating modified tumor-free techniques (LRH-MTF) is non-inferior to abdominal radical hysterectomy (ARH) in terms of disease-free survival at 4.5 years post-operation. A non-inferiority margin of 7% is set based on previous studies. This means that as long as the difference in the 4.5-year disease-free survival rate between LRH-MTF and ARH is within this non-inferiority margin, LRH-MTF will be considered non-inferior to ARH. If LRH-MTF meets this criterion, it can potentially offer the advantages of minimally invasive surgery, such as reduced surgical trauma, shorter hospital stay, and faster recovery, while maintaining comparable oncological outcomes.'}, 'enrollmentInfo': {'type': 'ESTIMATED', 'count': 524}}, 'statusModule': {'overallStatus': 'RECRUITING', 'startDateStruct': {'date': '2025-02-20', 'type': 'ACTUAL'}, 'expandedAccessInfo': {'hasExpandedAccess': False}, 'statusVerifiedDate': '2025-02', 'completionDateStruct': {'date': '2032-07', 'type': 'ESTIMATED'}, 'lastUpdateSubmitDate': '2025-04-23', 'studyFirstSubmitDate': '2025-02-11', 'studyFirstSubmitQcDate': '2025-02-15', 'lastUpdatePostDateStruct': {'date': '2025-04-27', 'type': 'ACTUAL'}, 'studyFirstPostDateStruct': {'date': '2025-02-20', 'type': 'ACTUAL'}, 'primaryCompletionDateStruct': {'date': '2032-07', 'type': 'ESTIMATED'}}, 'outcomesModule': {'primaryOutcomes': [{'measure': '4.5-year Disease-free Survival', 'timeFrame': 'From enrollment to the 4.5 years after the end of treatment', 'description': 'The time from randomization until the first recurrence or death from any cause within 4.5 years after surgery.
