|
Objectives of Study: |
To validate the diagnostic performance of an intelligent prediction system for tumor relative position based on CT imaging in detecting occult lymph node metastasis (OLNM); to evaluate through a multicenter double-blind human-machine collaborative study the substantial improvement in diagnostic accuracy that AI provides to physicians at various levels; and to quantify the net reclassification improvement (NRI) and clinical net benefit of this system in surgical extent decision-making. |

Inclusion criteria |
1. Age 18-90 years. 2. Preoperative clinical staging of cT1a-T2aN0M0 according to the 8th edition of the Union for International Cancer Control (UICC) TNM staging system. 3. High-resolution computed tomography (HRCT) of the chest with thin-slice acquisition (slice thickness ≤2.5mm) performed within 1 month prior to surgery, either non-contrast or contrast-enhanced, without significant respiratory motion artifacts, with complete and available DICOM data. 4. CT imaging demonstrates target lesions as solid nodules or part-solid nodules with predominant solid component (>25%), without radiological evidence of hilar or mediastinal lymph nodes with short-axis diameter >10mm or fusion. 5. Underwent anatomical lobectomy or segmentectomy with concurrent systematic lymph node dissection (e.g., right side: stations 2R, 4R, 7, 9, 11; left side: stations 5, 6, 7, 9, 11) or standardized lymph node sampling (at least 3 stations, including station 7). 6. Postoperative paraffin pathology confirmed as primary invasive lung adenocarcinoma. |

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: |
本研究的数据采集与管理遵循多中心临床研究的严格规范,确保全流程的标准化与可追溯性。数据采集通过标准化电子病例报告表(eCRF)进行,由各中心研究助理回顾性提取患者的临床病理特征(如年龄、性别、CEA水平)、影像学特征(肿瘤大小、位置、毛刺征等)及术后病理结果(淋巴结转移站数、个数),原始CT影像数据统一采集为512×512矩阵的DICOM格式;所有数据经双人独立录入“临床研究数据管理系统”(如REDCap或Medidata Rave),通过预设的逻辑校验规则进行实时质控,对缺失值与异常值进行标记与复核;影像组学特征提取前进行直方图标准化预处理,建立中心级数据隔离与权限控制机制,确保数据的完整性、准确性与安全性。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data collection and management in this study strictly adhered to the rigorous standards of multi-center clinical research, ensuring standardization and traceability throughout the entire process. Data were collected via standardized electronic Case Report Forms (eCRF), with research assistants at each center retrospectively extracting clinical and pathological characteristics (e.g., age, sex, CEA levels), imaging features (e.g., tumor size, location, spiculation), and postoperative pathological results (e.g., number and stations of lymph node metastases). Raw CT imaging data were uniformly acquired in DICOM format with a 512×512 matrix. All data were independently entered by two personnel into a Clinical Research Data Management System (such as REDCap or Medidata Rave). Real-time quality control was performed using predefined logical validation rules to flag and verify missing or abnormal values. Prior to radiomics feature extraction, histogram standardization preprocessing was applied. Furthermore, a center-level data isolation and access control mechanism was established to ensure data integrity, accuracy, and security. |
