Study of Laparoscopic Radical Hysterectomy Based on Space Anatomy in Patients With IB3 and IIA2 Cervical Cancer

January 3, 2025 updated by: International Peace Maternity and Child Health Hospital

Comparison Between Laparoscopic Radical Hysterectomy Based on Space Anatomy and Abdominal Radical Hysterectomy for Stage IB3 and IIA2 Cervical Cancer: a Multicenter Retrospective Cohort Study

Radical hysterectomy is an effect treatment for FIGO IB3 and IIA2 cervical cancer patients who refuse to receive radical concurrent chemoradiotherapy. However, due to the large tumor size, both patients and surgeons encountered the risk of substantial bleeding, urinary tract damage, and unsatisfactory resection during surgery. Therefore, the exploration of effective and safe surgical treatments is crucial in enhancing the quality of life and prognosis for patients. Laparoscopic radical hysterectomy (LRH) offers the advantages of reduced bleeding and accelerated recovery, thereby minimizing patient discomfort and enhancing their quality of life. However, the prognosis of patients who received LRH or traditional abdominal radical hysterectomy (ARH) remains controversial. We proposed a modified LRH skill based on new space anatomy concept. In our previous single-center study, the result demonstrates that LRH based on space anatomy leads to less intraoperative blood loss and decreased ureteral injury rate compared with traditional skill. The benefits of this new method for patient survival remain uncertain. In this multicenter retrospective study, we aim to assess clinical prognosis and safety of this new LRH compared with traditional abdominal radical hysterectomy (ARH) in FIGO IB3 and IIA2 cervical cancer.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Contacts and Locations

This section provides the contact details for those conducting the study, and information on where this study is being conducted.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
LRH group
In this group, patients received a modified laparoscopic radical hysterectomy(LRH) based on space antomy.
Procedure: Laparoscopic radical hysterectomy based on space anatomy
This is a modified laparoscopic radical hysterectomy based on space anatomy. By identifying the vesicouterine ligament and four associated special spaces, the ureter can be completely liberated from the external aspect of the uterus. This skill not only reduces rate of surgical complications but also facilitates optimal tumor resection.
ARH group
In this group, patients received a traditional abdominal radical hysterectomy(ARH). ARH group is defined as a control group.
Procedure: Abdominal radical hysterectomy
This producre is a classic and traditional radical hysterectomy.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Overall survival
Time Frame: 5 years
The time from end of surgery to death from any cause.
5 years
Progression-free survival
Time Frame: 5 years
The time from end of surgery to either the first documented disease progression or death from any cause.
5 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Surgery complication rate
Time Frame: Intraoperative or within 2 weeks after surgery
Including the rates of ureter or bladder injury, colon injury, deep vein thrombosis event and infection.
Intraoperative or within 2 weeks after surgery
Intraoperative blood loss
Time Frame: Intraoperative blood loss
Intraoperative blood loss
