Modified Tumor-free Techniques Operation to Cervical Cancer

Official title

A Multicenter, Non-inferiority Trial to Compare the Effectiveness and Safety of Laparoscopic Radical Hysterectomy Incorporating Modified Tumor-free Techniques Versus Abdominal Radical Hysterectomy in Patients With Stage IB2 Cervical Cancer

Overview

The goal of this clinical trial is to learn if laparoscopic radical hysterectomy incorporating modified tumor-free techniques (LRH-MTF) works to treat FIGO stage IB2 cervical cancer as good as abdominal radical hysterectomy (ARH). It will also learn about the safety of LRH-MTF. The main questions it aims to answer are: Does LRH-MTF achieve a non-inferior disease-free survival rate at 4.5 years post - operation compared to ARH? What complications do patients have during and after the operation when receiving LRH-MTF? Researchers will compare LRH-MTF to ARH to see if LRH-MTF works no worse than ARH in treating FIGO stage IB2 cervical cancer. Participants will: 1. Undergo either LRH-MTF or ARH as assigned by randomization. 2. Visit the hospital for follow-up according to the study schedule for various examinations including blood tests, imaging studies, and assessment of complications. 3. Complete quality-of-life questionnaires such as EORTC QLQ-C30, QLQ-CX24, FSFI, and FSDS-R at baseline (pre-operation) and specific time points during the follow - up period (post-operation 6 months, 1 year, 2 years, 3 years, 4.5 years).

Detailed description

A progress report will be conducted within 4 weeks after all participants have completed their 6-month postoperative visit (the 5th visit). The report will be performed by an independent third-party statistical team, which will provide a comprehensive analysis of the safety data, baseline characteristic, and perioperative indicators.

The study will perform one final analysis.

Interventions

• Procedure Laparoscopic radical hysterectomy incorporating modified tumor-free techniques
  Thoroughly examine the pelvic and abdominal cavities. Coagulation of the fallopian tubes are recommanded at the beginning of the surgery. The use of uterine manipulator is prohibited. An "8"-suture at the uterine fundus is recommended. Insert a trocar 3 cm above the pubic symphysis and suspend the uterus by pulling with a needle holder. Alternative methods are also acceptable. Perform pelvic lymphadenectomy. Conduct radical hysterectomy according to the Q-M classification type C. Before incising
• Procedure Abdominal radical hysterectomy
  At the onset of surgery, comprehensively explore the pelvic and abdominal cavities. If intraperitoneal metastases are identified, radical hysterectomy should be aborted. Perform pelvic lymphadenectomy. After lymph node resection, remove the lymph nodes from the surgical field promptly. Sentinel lymph node mapping and biopsy are not performed in this study. Perform radical hysterectomy according to type C of the Q-M classification. It can be accompanied by or without bilateral salpingo - oophorec

Eligibility criteria

• Inclusion Criteria:

1.10 Laboratory test indicators of vital organs meet the standards

• Exclusion Criteria:

2.1 Special pathological types (gastric - type adenocarcinoma, neuroendocrine carcinoma, clear cell carcinoma, carcinosarcoma, etc.).

2.2 Imaging examinations suggest pelvic or para - aortic lymph node metastasis (MRI or CT shows a short - axis diameter of ≥1.5 cm, or SUV ≥2.5), or histopathology indicates lymph node metastasis.

2.3 History of pelvic and abdominal radiotherapy. 2.4 History of neoadjuvant chemotherapy. 2.5 Uterus larger than that at 10 weeks of pregnancy. 2.6 Contraindications for surgery and anesthesia (such as severe medical comorbidities).

2.7 Patients who cannot tolerate the Trendelenburg position. 2.8 Patients who cannot cooperate with treatment and follow - up. 2.9 Pregnant patients. 2.10 History of other malignancies, except for those who have been cancer - free for more than 3 years with no current evidence of tumor recurrence.

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
