研究目的: |
主要目的:本研究拟建立一套直肠癌影像-病理结节一一对应方法,以病理诊断为金标准,前瞻性验证MRI诊断肿瘤沉积物(TDs)的准确性。 次要目的: 1. 分析TDs的MRI的影像特征,进而构建基于影像学特征的 TDs 诊断标准。 2. 明确影像学及病理诊断的TDs对局部复发、无病生存期和总体生存期的影响。 3. 评估病理学家之间以及放射科医生之间的观察者间一致性。 4. 基于病理金标准分析、验证MRI图像中鉴别 TDs 与 EMVI、淋巴结转移的方法。 |

|
Objectives of Study: |
Main Objective: This study aims to establish a one-to-one correspondence method between rectal cancer imaging and pathological nodules, using pathological diagnosis as the gold standard, and prospectively verify the accuracy of MRI in diagnosing tumor deposits (TDs). Secondary Objectives: 1. Analyze the MRI imaging features of TDs and construct a diagnostic standard for TDs based on imaging features. 2. Clarify the impact of imaging and pathological diagnosis of TDs on local recurrence, disease-free survival, and overall survival. 3. Evaluate the interobserver agreement between pathologists and radiologists. 4. Analyze and validate methods for distinguishing TDs from extramural vascular invasion (EMVI) and lymph node metastasis in MRI images based on the pathological gold standard. |

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: |
患者详细信息,包括人口统计学和临床特征,如确诊年龄、性别、肿瘤位置(高、中、低位直肠)以及术前癌胚抗原和 CA19-9 水平通过医院病历系统检索并收集。数据将通过使用医院系统内分配的唯一患者识别号进行匿名化。放射学和病理结果以及治疗数据也将被记录下来。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Patient details, including demographic and clinical characteristics such as age at diagnosis, gender, tumor location (High, middle and low rectum), as well as preoperative carcinoembryonic antigen and CA19-9 levels, were retrieved and collected through the hospital's medical record system. The data will be anonymized by using the unique patient identification number (ID) assigned within the hospital system. Radiological and pathological results as well as treatment data will also be recorded. |
