摘要

目的:探讨决策树（Decision tree）模型从乳腺癌病例信息中自动提取诊断规则

用于乳腺癌腋窝高位淋巴结判别分类诊断研究的计算机辅助诊断系统。方法:利用重庆医科大学1998～2002年普外科223例手术证实的乳腺癌患者11项指标

采用C5算法、CR算法、QUEST算法及（Chi-square automatic interaction detector

CHAID）算法4种决策树算法

建立了乳腺癌腋窝高位淋巴结判别分类模型。结果:建立的CHAID判别分类模型的准确率为83.79%

CHAID模型所获知识的可靠程度以及对测试集合的准确率明显优于Logistic模型。结论:CHAID模型可从病例自动提取诊断规则

具有较广泛的实用价值

可应用于乳腺癌腋窝高位淋巴结判别分类的诊断。

Abstract

Objective:Todiscuss the application of Decision Tree model and fit classification model of maxillary Ⅲ lymph nodes of breast cancer

which can abstract diagnostic knowledge used for computer-based diagnosis system.Methods:Four classification models of Decision Tree with the arithmetic of C5

QUEST and CHAID were applied for classifying maxillary Ⅲ lymph nodes in 223 cases of breast cancers

confirmed by with 11 diagnostic indexes in the first affiliated hospital of chongqing medical university from 1993 to 2003.Results:CHAID classification model was better than other three models

according to the reliability of diagnostic knowledge and the accuracy of the test samples

the accuracy being 83.79%.Conclusion:The diagnostic knowledge of CHAID classification model automatically from the cases can be used to classify maxillary Ⅲ lymph nodes of breast cancer and other diseases.It is worth of widely practical use.
