Three-dimensional Study on the Structural Destruction of Pelvic Anatomy in Cervical Cancer

May 15, 2017 updated by: Nanfang Hospital of Southern Medical University

Three-dimensional Study on the Structural Destruction of Pelvic Organs and Pelvic Floor After Radical Hysterectomy in Cervical Cancer

Cervical cancer is one of the most prevalent malignancies in female .To the younger patients, radical hysterectomy which is a standard operation during the earlier and middle therapy stage as well as more effective technique like radiotherapy and chemotherapy give them a longer life expectancy. However, the operation destroys patients' normal pelvic anatomy, nutrient supplements and internal secretion so that postoperative pelvic floor functional dysfunction has a destructive effect for their life. There are tremendous studies on clinical symptoms while few on anatomical changes and the relationship between pelvic floor symptoms and the dysfunction. Two-dimensional Magnetic Resonance Imaging(MRI), transperineal ultrasonography， Urodynamic examination and anorectal manometry are frequently used in the fine-structure varies and pelvic floor function. Now three-dimensional MRI has more advantages in fine change of Pelvic anatomical and space position，as well as clearly showing the relationships between the change and space with the pelvic floor function. Based on an eight-year-study on three-dimensional MRI, we can analyze the postoperational anatomical changes and the relationship between the changes and the dysfunction by combined anatomic parameters which are measured on static-dynamic three- dimensional model with clinical symptoms, transperineal ultrasonography,urodynamic examination and anorectal manometry. We expect our study could provide scientific basis for on protective and repaired measures of pelvic floor.

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

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.

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.
radical hysterectomy group

Using dynamic MRI and 3D reconstruction to assess the effect of RH on pelvic floor muscles and pelvic organs (location and mobility of bladder neck and urethral).

Inclusion Criteria： ①Patients diagnosed as FIGO stage IA2、IB1、IIA1 cervical cancer ; ②Patients diagnosed as FIGO stage IB2、IIA2 cervical cancer, eligible for RH after neoadjuvant chemotherapy; ③Patients diagnosed as FIGO stage IIA endometrial carcinoma; ④Patients didn't have pelvic organ prolapse and urinary incontinence; ⑤Ability to hold Valsalva for dynamic MRI; ⑥Patients aged 20-70 years; ⑦Patients undergone RH surgery; ⑧Informed consent was signed.

Exclusion Criteria：

①With MRI or urodynamic examination contraindication; ②Previously undergone POP or SUI surgery; ③BMI>30 ④With serious postoperative complications.
Procedure: radical hysterectomy
A standard radical hysterectomy with lymphadenectomy was performed. Static and dynamic MRI were performed. A suggested urodynamic examination was done according to the ICS. A 3D reconstruction technique was used to construct the 3D model of the pelvis, pelvic floor muscle, pelvic organ such as bladder and urethral.

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.

september 3,2017 to september 1,2019

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
Time Frame
Bladder，uterus and rectum space coordinates.

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
