Preliminary Study on the Metastatic Rate and Clinical Significance of the Anterior Leaf of Vesicouterine Ligament in Early Stage Cervical Cancer

June 14, 2023 updated by: Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University
The purpose of this study is to preliminarily explore the metastatic rate and clinical significance of the anterior leaf of vesicouterine ligament resection for early stage cervical cancer, so as to further improve the postoperative quality of life of patients and reduce the incidence of postoperative urinary complications.

Detailed Description

The patients with cervical cancer who underwent abdominal radical hysterectomy（type C）plus pelvic lymph node dissection by the same surgical team at the Department of Gynecological Oncology, Sun Yat-sen Memorial Hospital, Sun Yat-Sen University, were included. According to the resection range of the anterior leaf of vesicouterine ligament (VUL), patients were divided into type C resection group (near the bladder wall) and B type resection group (above the ureter). The anterior leaf of the VUL in the type C resection group was sent to pathological biopsy separately, and the metastasis rate was further clarified by the pathological "ultrastaging" method. By comparing the clinicopathological characteristics of patients with metastasis and non-metastasis, the potential risk factors of VUL metastasis were analyzed. The oncological outcomes of patients with different resection range of the anterior VUL were compared. At the same time, the Functional Assessment of Cancer Therapy-Cervical（FACT-Cx）cervical cancer patient quality of life score table was used to evaluate cervical cancer patients after surgery. The relevant factors that may affect the quality of life score are included in the multiple linear regression analysis to obtain independent risk factors that affect the quality of life of the patient after surgery.

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
Metastatic rate of the anterior leaf of vesicouterine ligament
Time Frame: 1 year (Postoperative pathological confirmation date)
The metastasis rate of anterior leaf of VUL (%) = (case number of positive metastatic lesion detected by H&E staining + case number of positive metastatic lesion diagnosed by "ultrastaging") / Total number of the patients with cervical cancer who underwent abdominal radical hysterectomy（type C）plus pelvic lymph node dissection by the samesurgical team ×100%
1 year (Postoperative pathological confirmation date)

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
