This paper aims to analyze the multifactorial factors of lateral lymph node metastasis in middle and low rectal cancer, in order to provide more comprehensive and accurate prognosis evaluation guidance.Firstly, we will collect the medical history, clinical data and imaging examination data of middle and low rectal cancer patients, and combine with surgical and postoperative pathological reports to statistically analyze the relationship between relevant factors and lateral lymph node metastasis. Secondly, we will use multiple logistic regression and decision tree analysis to establish the prediction model, further study the impact of each factor on the prediction of lateral lymph node metastasis, and improve the accuracy and reliability of prediction.The expected purpose of this study is to provide clinicians with more comprehensive and scientific evaluation basis through multifactorial analysis of lateral lymph node 精品文档---下载后可任意编辑metastasis in middle and low rectal cancer, promote early detection, early intervention and prevention of lateral lymph node metastasis in middle and low rectal cancer, and improve the quality of life of patients.【Keywords】Middle and low rectal cancer; Lateral lymph node metastasis; Multifactorial analysis; Prediction model
