摘要

目的：应用二分类Logistic回归模型分析浅表淋巴结良恶性的超声鉴别诊断。方法：对171例经穿刺病理及随访证实良恶性的浅表淋巴结声像图进行分析，通过二分类Logistic回归模型筛选良恶性鉴别诊断的超声检查指标，并检验这些指标是否有统计学意义。结果：经前进法逐步回归的多变量二分类Logistic回归分析，筛选引入方程的超声检查指标包括：有无淋巴门结构、长短径比值的赋值、是否有透声区、血流是否丰富、血流类型以及协变量年龄和性别，所有这些指标均为良恶性淋巴结比较χ2检验有显著统计学差异的指标。同时显示，血流信号类型变化，淋巴结为恶性可能性也有变化。结论：二分类Logistic回归多元分析模型能够很好地描述和分析良恶性淋巴结的超声鉴别诊断的过程, 并能筛选出有意义的鉴别诊断指标。

Abstract

Objective: To apply the binary Logistic regression model to analyze the ultrasonogrphic differential diagnosis of benign and malignant superficial lymph nodes. Methods: The ultrasonography of superficial lymph nodes of 171 patients proved by pathology and follow-up were analyzed, and we selected the indexes of differential diagnosis through the model of binary Logistic regression analysis to see if these were statistical significance. Results: All indexes of ultrasonography were analyzed by the multivariable binary Logistic regression model through the forward stepwise. Some of those indexes were selected out and induced in the equation, which included: having the normal lymph hilum or not, the recode by the ratio of longitudinal over short diameter, having the area of acoustic transmission or not, the signal of the blood flow rich or scarce, the signal types of the blood flow, and the covariates of age and sex． Moreover, all those indexes were included of the indexes which had significant statistical differences using χ2 test. Meanwhile, the results shown that the malignant probability of a lymph node would change with altering of the signal types of blood flow. Conclusion: The multivariate analysis model of binary Logistic regression can describe and analyze the process of differential diagnosis of malignant and benign lymph nodes by ultrasonography, and can select out the valuable indexes of differential diagnosis.
