研究目的: |
本研究旨在针对接受胃肠道内镜检查并发现可疑黏膜病变的成人患者(目标人群),以组织病理学诊断为金标准,系统评估整合临床特征、内镜表现、增强CT及MRI多模态影像参数所构建的综合诊断模型在鉴别炎症性病变与肿瘤性病变中的准确性。具体而言,本研究拟回答以下临床科学问题:(1)该多模态综合模型能否显著提高对胃肠道炎症性与肿瘤性病变的鉴别诊断效能(以AUC、敏感性、特异性为主要指标)?(2)相较于单一模态(如仅临床判断、仅内镜或仅影像学评估),多源信息融合是否具有统计学和临床意义上的优势?通过回答上述问题,为优化胃肠道病变的精准分诊与个体化诊疗提供循证依据。 |

Objectives of Study: |
This study aims to systematically evaluate the accuracy of a comprehensive diagnostic model, constructed by integrating clinical characteristics, endoscopic findings, and multimodal imaging parameters including enhanced CT and MRI, in distinguishing between inflammatory and neoplastic lesions in adult patients (target population) who have undergone gastrointestinal endoscopy and have suspicious mucosal lesions identified. The histopathological diagnosis serves as the gold standard. Specifically, this study intends to answer the following clinical scientific questions: (1) Can this multimodal comprehensive model significantly improve the diagnostic efficacy in distinguishing between gastrointestinal inflammatory and neoplastic lesions (using AUC, sensitivity, and specificity as the main indicators)? (2) Compared to single modality (such as clinical judgment alone, endoscopy alone, or imaging assessment alone), does multi-source information fusion have statistical and clinical advantages? By answering these questions, we aim to provide evidence-based support for optimizing the precise diagnosis and individualized treatment of gastrointestinal lesions. |

Inclusion criteria |
1. Aged >= 18 years old, with no gender restrictions; 2. Underwent gastrointestinal endoscopy (including gastroscopy, colonoscopy, or small intestinal endoscopy) at our hospital, and at least one suspicious mucosal lesion was found during the examination (defined as abnormal mucosal manifestations such as erosion, ulceration, protrusion, indentation, abnormal color, or vascular texture disorder under endoscopy); 3. Complete abdominal and/or pelvic enhanced CT and/or MRI examinations within 4 weeks before and 4 weeks after endoscopy, with imaging coverage of the anatomical region where the lesion is located; 4. Obtain tissue specimens from suspicious lesion sites (via biopsy, EMR, ESD, or surgery) and obtain a definitive histopathological diagnosis, ultimately categorized into one of the following two types: (1) Inflammatory lesions: such as chronic gastritis, inflammatory bowel disease (IBD), infectious or eosinophilic gastroenteritis, etc., with pathological manifestations of chronic mucosal inflammation, inflammatory cell infiltration, crypt structural changes, and no epithelial dysplasia; (2) Neoplastic lesions: including low-grade/high-grade dysplasia (LGD/HGD), adenoma, early-stage cancer (stage T1 and below) or advanced cancer, diagnosed according to the "WHO Classification of Digestive System Tumors (5th Edition)"; 5. Clinical data (including symptom duration, laboratory indicators such as C-reactive protein), endoscopic images, CT/MRI raw images, and pathological reports are complete and traceable; 6. Meet the requirements of informed consent: Prospective patients enrolled must sign a written informed consent form; data from retrospective cases have been approved by the ethics committee for exemption from individual informed consent and comply with relevant national regulations. |
||||||||||||||||||||||
|
排除标准: |
符合以下任一情形者不予纳入: 1.病理诊断不明确或存在争议,且经多学科会诊(MDT)仍无法达成一致分类; 2.合并活动性消化道大出血(24小时内需输血或内镜干预)、穿孔、完全性肠梗阻等急性胃肠道并发症,可能干扰目标病变评估; 3.CT或MRI图像质量差,存在严重运动伪影、金属伪影、扫描范围不足或对比剂注射失败,导致关键影像特征无法判读; 4.内镜图像缺失,或临床资料严重不全(如症状病程、既往治疗史、C反应蛋白等关键变量缺失),影响分析; 5.妊娠或哺乳期女性(因涉及CT辐射暴露及碘/钆对比剂使用,存在潜在风险)。 |
||||||||||||||||||||||
|
Exclusion criteria: |
Those who meet any of the following conditions shall not be included: 1. The pathological diagnosis is unclear or controversial, and consensus cannot be reached on classification even after multidisciplinary team (MDT) consultation; 2. The presence of acute gastrointestinal complications such as active gastrointestinal bleeding (requiring blood transfusion or endoscopic intervention within 24 hours), perforation, and complete intestinal obstruction may interfere with the assessment of the target lesion; 3. Poor quality of CT or MRI images, with severe motion artifacts, metal artifacts, insufficient scanning range, or failed contrast agent injection, resulting in unreadable key imaging features; 4. The absence of endoscopic images, or severe incompleteness of clinical data (such as missing key variables like symptom duration, previous treatment history, C-reactive protein levels, etc.), impacts the analysis; 5. Pregnant or lactating women (due to potential risks associated with CT radiation exposure and the use of iodine/gadolinium contrast agents). |

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: |
前瞻性研究利用病例记录表采集数据。 回顾性研究的数据均来源于参与医院的影像归档与通信系统(PACS) 和电子病历系统(EMR)。 研究团队使用标准化数据提取表格(基于电子表格,如Microsoft Excel) 从上述系统中提取符合研究方案的匿名化数据。提取后的数据将汇集并存储在由主要研究单位(复旦大学附属中山医院)管理的、加密的专用科研服务器中,进行后续的清洗、整理和分析。 本研究未使用商业化的电子数据采集系统。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Prospective studies utilize case record forms to collect data. The data for the retrospective study were sourced from the Picture Archiving and Communication System (PACS) and the Electronic Medical Record (EMR) systems of the participating hospitals. The research team utilizes standardized data extraction forms (based on electronic spreadsheets, such as Microsoft Excel) to extract anonymized data from the aforementioned systems that meet the research protocol. The extracted data will be compiled and stored on an encrypted, dedicated research server managed by the primary research institution (Zhongshan Hospital, Fudan University) for subsequent cleaning, organization, and analysis. This study did not utilize a commercial electronic data capture system. |
