研究设计:

队列研究 

Study design:

Cohort study 

研究目的:

1.主要目的:开发并验证一个结合了手术切缘组织“胶原组学”特征与临床病理资料的多因素预测模型,用于预测接受新辅助放化疗的直肠癌患者术后发生重度LARS的风险。 2.次要目的:定量描述并比较重度LARS组与非重度LARS组患者手术切缘组织中胶原纤维的微观结构特征差异  

Objectives of Study:

1. Primary Objective: To develop and validate a multivariate predictive model combining surgical margin tissue collagen signature with clinicopathological data to predict the risk of major low anterior resection syndrome (LARS) in rectal cancer patients receiving neoadjuvant chemoradiotherapy. 2. Secondary Objective: To quantitatively describe and compare the differences in the microstructural characteristics of collagen fibers in surgical margin tissues between patients with major LARS and those without.

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:

数据来自医院电子病历系统,纳入符合标准的连续患者。对预先设计的病例资料表格收集人口学、肿瘤学与治疗相关变量;随访数据(LARS问卷)通过电话随访。所有数据在本地去标识化后录入本地数据库。数据仅限授权研究成员访问。

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

Data were obtained from the hospital's electronic medical record system , including consecutive patients who met the criteria. Demographic, oncological, and treatment-related variables were collected from a pre-designed case data form; follow-up data (LARS questionnaire) were obtained via telephone. All data were de-identified locally before being entered into a local database. Data is accessible only to authorized research members.
