乳腺癌患者的超声特征及其影响因素

Ultrasonic characteristics of breast cancer patients and their influencing factors

目的探讨乳腺癌患者的超声特征及其影响因素。方法选取75例乳腺癌患者和125例乳腺良性疾病患者,分别作为观察组和对照组。比较两组患者的超声特征,比较不同临床特征乳腺癌患者的超声特征,采用Logistic回归模型分析乳腺癌患者超声特征的影响因素。结果观察组中肿块形状不规则、后方回声弱、血流分级≥Ⅱ级、阻力指数﹥0.08的患者比例均明显高于对照组,差异均有统计学意义(P﹤0.01)。中低分化、有淋巴结转移、Ⅲ~Ⅳ期乳腺癌患者肿块形状不规则、后方回声弱、血流分级≥Ⅱ级、阻力指数﹥0.08的比例分别高于高分化、无淋巴结转移、Ⅰ~Ⅱ期患者,差异均有统计学意义(P﹤0.05)。多因素回归分析结果显示,分化程度是乳腺癌患者肿块形状不规则、后方回声弱、血流分级≥Ⅱ级以及阻力指数﹥0.08的独立影响因素(P﹤0.05)。结论超声检查对乳腺癌具有一定的诊断作用,且不同临床特征的乳腺癌患者的超声特征不同。

Objective To explore the ultrasonic characteristics of breast cancer patients and their influencing factors.Method A total of 75 patients with breast cancer and 125 patients with benign breast diseases were selected and divided into observation group and control group.The ultrasonic characteristics in two groups and in breast cancer patients with different clinical characteristics were compared.And the factors influencing the ultrasonic characteristics in breast cancer patients were analyzed by Logistic regression model.Result The proportion of tumor irregular shape,weak rear echo,blood flow≥grade II,and resistance index>0.08 in the observation group were higher than those in the control group(P<0.01).The proportion of tumor irregular shape,weak rear echo,blood flow≥grade II,and resistance index>0.08 in breast cancer patients with moderate or poor differentiation,lymph node metastasis,and TNM stage III-IV were higher than those with high differentiation,no lymph node metastasis,and TNM stage I-II(P<0.05).Multifactor regression analysis showed that the differentiation degree was the independent influencing factor for tumor irregular shape,weak rear echo,blood flow≥grade II,and resistance index>0.08 in breast cancer patients(P<0.05).Conclusion Ultrasonic examination has a certain diagnostic effect in breast cancer patients,and the characteristics of ultrasonography are different in breast cancer patients with different clinical characteristics.
