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.

纳入标准:

1、经病理学检查确诊为结直肠腺癌患者。 2、接受根治性手术切除。 3、年龄在18岁以上。 4、完成术后随访并具备临床病理特征数据。

Inclusion criteria

1. Patients diagnosed with colorectal cancer by pathological examination. 2. Undergoing radical surgical resection. 3. Aged 18 years or older. 4. Completed postoperative follow-up and had clinical and pathological data.

排除标准:

1.存在其他类型癌症的活跃病例或治疗历史。 2.缺乏完整的治疗或随访数据。 3.病理样本因固定、处理不当或保存时间过长导致质量不佳,无法进行有效的机器学习分析。 4.有影响预后评估的严重合并症,如未控制的心脏病、肝功能衰竭等。 5.未满18岁的患者。

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.
