研究目的: |
这项多中心回顾性研究旨在开发并验证一种基于病理组学的机器学习模型,用于预测结直肠癌 (CRC) 根治性切除术后的早期复发 (ER)。通过从常规苏木精和伊红 (H&E) 染色的全切片图像中提取定量特征并应用机器学习算法,我们力求提供一种准确且可重复的个体化 ER 风险评估工具,从而解决当前临床预测指标的局限性并支持 CRC 患者的术后监测和治疗决策。 |

|
Objectives of Study: |
The aim of this multicenter retrospective study was to develop and validate a pathomics-based machine learning model for predicting early recurrence (ER) after curative resection of colorectal cancer (CRC). By extracting quantitative features from routine hematoxylin and eosin (H&E)–stained whole-slide images and applying machine learning algorithms, we sought to provide an accurate and reproducible tool for individualized ER risk assessment, thereby addressing the limitations of current clinical predictors and supporting postoperative surveillance and treatment decision-making in CRC patients. |

Exclusion criteria: |
1. Other cancer history: Presence of an active case or treatment history of other types of cancer. 2. Incomplete data: Lack of complete treatment or follow-up data. 3. Poor sample quality: Pathological samples of poor quality due to improper fixation, handling, or prolonged storage, making them unsuitable for effective machine learning analysis. 4. Serious comorbidities: Presence of serious comorbidities that affect prognosis assessment, such as uncontrolled heart disease, liver failure, etc. 5. Age restriction: Patients under the age of 18. |
