研究目的: |
本研究为一项前瞻性、观察性研究。在常规临床诊疗流程基础上,系统性地收集直肠癌患者术前合成磁共振成像(Synthetic MRI)的定量参数、术后病理结果(包括微卫星不稳定状态及肠周肿瘤沉积)及随访数据。 主要目的:观察并分析合成磁共振成像的定量参数与直肠癌微卫星不稳定状态及肠周肿瘤沉积之间的关联性。 次要目的:评估合成磁共振成像在直肠癌术前评估中的图像质量。 |

Objectives of Study: |
This is a prospective, observational study. Based on the routine clinical diagnosis and treatment pathway, we will systematically collect preoperative synthetic magnetic resonance imaging (synthetic MRI) quantitative parameters, postoperative pathological results (including microsatellite instability status and peritumoral deposits), and follow-up data from rectal cancer patients. Primary Objective: To observe and analyze the association between quantitative parameters of synthetic MRI and both microsatellite instability status and peritumoral deposits in rectal cancer. Secondary Objective: To evaluate the image quality of synthetic MRI for preoperative assessment of rectal cancer. |

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: |
本研究的数据采集和管理由两部分组成:一是病例记录表(CRF),二是电子数据采集和管理系统(EDC)。 CRF用于系统记录研究对象的临床、影像及病理数据。所有数据由研究人员依据统一标准填写,并进行核对和整理。核对后的数据录入至EDC 系统进行集中管理。EDC 系统设置分级访问权限,确保数据录入、修改和查询过程可追溯。研究数据采用去标识化方式存储,仅限研究团队授权成员访问,用于科研分析,不涉及患者个人身份信息的公开或传播。研究过程中将定期进行数据质量控制和备份,确保数据的安全性、完整性和可靠性。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
The data collection and management in this study consist of two components: Case Report Forms (CRFs) and an Electronic Data Capture (EDC) system. CRFs are used to systematically record clinical, imaging, and pathological data of the study subjects. All data are collected by researchers according to standardized procedures and are verified and organized before entry. Verified data are then entered into the EDC system for centralized management. The EDC system implements role-based access controls to ensure that the processes of data entry, modification, and querying are traceable. Study data are stored in a de-identified format and are accessible only to authorized members of the research team for scientific analysis, without disclosure or dissemination of patients’ personal identity information. Regular data quality control and backup procedures are carried out throughout the study to ensure data security, integrity, and reliability. |
