研究目的:

1.比较 vNOTES 与 LPS 手术路径下,早期宫颈癌术后辅助放疗的3 年≥2 级晚期胃肠道、泌尿系统毒性发生率及 95% CI,明确两种手术路径的毒性差异。 2.分析两种手术路径的手术康复指标(手术时间、术中出血量等)、放疗启动时间及放疗中断率、剂量调整率,评估手术路径对整体治疗流程的影响。 3.基于 RTOG/NRG 靶区勾画共识,评估两种手术路径对盆腔解剖结构、放疗靶区剂量分布(CTV-Pelvis D95、PTV 覆盖度)及正常器官受量(直肠 V40、膀胱 V40 等)的影响。 4.观察两种手术路径下术后放化疗的急性毒性发生率,及放疗后 1 年、3 年、5 年的生活质量评分,全面评估治疗的安全性与患者获益。 5.对比两种手术路径下患者的无病生存期(DFS)、总生存期(OS)、局部复发率及远处转移率,验证 vNOTES 路径的肿瘤学疗效非劣效性。  

Objectives of Study:

1. Compare the 3-year ≥ grade 2 late gastrointestinal and urinary system toxicity rates and 95% CI after adjuvant radiotherapy in early cervical cancer patients who underwent vNOTES versus LPS surgical pathways, to clarify the toxicity differences between the two surgical approaches. 2. Analyze surgical recovery indicators (operative time, intraoperative blood loss, etc.), radiotherapy initiation time, radiotherapy interruption rate, and dose adjustment rate for the two surgical pathways, to evaluate the impact of the surgical approach on the overall treatment process. 3. Based on the RTOG/NRG target delineation consensus, evaluate the impact of the two surgical pathways on pelvic anatomical structures, radiotherapy target dose distribution (CTV-Pelvis D95, PTV coverage), and normal organ doses (rectum V40, bladder V40, etc.). 4. Observe the incidence of acute toxicity during postoperative chemoradiotherapy in the two surgical pathways, and the quality of life scores at 1, 3, and 5 years after radiotherapy, to comprehensively assess treatment safety and patient benefit. 5. Compare disease-free survival (DFS), overall survival (OS), local recurrence rate, and distant metastasis rate between the two surgical pathways, to validate the non-inferiority of the oncological efficacy of the vNOTES approach.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

数据采集与管理包含两部分内容:一是采用病例记录表(CRF),对患者的基线资料、手术信息、放疗参数、不良事件、随访数据及生活质量评分等进行规范化记录;二是依托电子数据采集与管理系统(EDC)完成数据的电子化录入与集中管理。所有数据均由专人核对并双人录入,确保真实、完整。研究期间实行数据权限分级管理,并定期备份,保障数据安全与可追溯性。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data collection and management consists of two parts. First, case record forms (CRFs) are used to standardize the recording of patients' baseline data, surgical information, radiotherapy parameters, adverse events, follow-up data, quality of life scores and other related indicators. Second, an electronic data capture and management system (EDC) is employed for electronic data entry and centralized administration. All data are verified by dedicated personnel and entered by double entry to ensure authenticity and integrity. Hierarchical data access management is implemented during the study, with regular backups to guarantee data security and traceability.
