BACKGROUND/AIM: There are few studies on artificial intelligence-based prediction models for colon cancer built using clinicopathological factors. Here, we aimed to perform a preliminary evaluation of a novel artificial intelligence-based prediction model for surgical site infection (SSI) in patients with stage II-III colon cancer.
The medical records of 730 patients who underwent radical surgery for stage II-III colon cancer between 2000 and 2018 at our institute were retrospectively analyzed. Kaplan-Meier curves were used to examine the association between SSI and oncological outcomes (recurrence-free survival time). Next, we used the machine learning software Prediction One to predict SSI. Receiver-operating characteristic curve analysis was used to evaluate the accuracy of the artificial intelligence model.
The prognosis in terms of recurrence-free survival time was poor in patients with SSI (p=0.005, 95% confidence interval=4892.061-5525.251). The area under the curve of the artificial intelligence model in predicting SSI was 0.731.
As SSI is an important prognostic factor associated with oncological outcomes, the prediction of SSI occurrence is important. Based on our preliminary evaluation, the artificial intelligence model for predicting SSI in patients with stage II-III colon cancer was as accurate as the previously reported model derived through conventional statistical analysis.
背景/目的:利用临床病理因素构建基于人工智能的结肠癌预测模型的研究较少。在此,我们旨在对一种基于人工智能的II-III期结肠癌患者手术部位感染(SSI)预测模型进行初步评估。
回顾性分析了2000年至2018年在我院接受II-III期结肠癌根治手术的730例患者的病历。采用Kaplan-Meier曲线检验SSI与肿瘤学结局(无复发生存时间)之间的关联。接下来,我们使用机器学习软件Prediction One预测SSI。采用受试者工作特征曲线分析评估人工智能模型的准确性。
SSI患者的无复发生存时间预后较差(p=0.005,95%置信区间=4892.061-5525.251)。人工智能模型预测SSI的曲线下面积为0.731。
由于SSI是与肿瘤学结局相关的重要预后因素,预测SSI的发生很重要。基于我们的初步评估,用于预测II-III期结肠癌患者SSI的人工智能模型与先前通过传统统计分析得出的模型准确性相当。
