Abstract
Objective:To study the relationship between ultrasonic features of invasive breast cancer and axillary lymph node metastasis(ALNM).Methods:113 patients with invasive breast cancer who were admitted to Xi'an Gaoxin hospital from July 2020 to July 2022 were selected to carry out the experiment.The occurrence of ALNM was divided into ALNM group(n=48 cases)and non-ALnm group(n=65 cases).All patients were examined by ultrasound.Clinical data(including age,menopause,tumor diameter,clinical stage,and degree of differentiation)and ultrasonic characteristics(including shape,burr sign,posterior echo,microcalcification,blood flow grade,ax-illary lymph node diameter ratio,and axillary lymph node cortical thickness)were compared between the two groups.Multivariate Logistic regression analysis was used to determine the influencing factors of ALNM in breast invasive carcinoma.Results:The proportion of patients with tumor diameter ≥3cm and low differentiation in AL-NM group was 33.33％and 41.67％,which were higher than 16.92％and 18.46％in non-ALNM group(all P＜0.05).The percentages of people with burr sign and blood flow grade 2 to 3 in ALNM group were 52.08％and 72.92％,respectively,which were higher than 27.69％and 36.92％in the non-ALNM group,and the ratio of axial and transverse diameter of axillary lymph nodes and cortical thickness were(0.59±0.12)and(5.10±1.05)mm,respectively.It was higher than(0.48±0.10)and(2.88±0.56)mm in the non-ALnm group(P＜0.05).Multivariate Logistic regression analysis confirmed that tumor diameter ≥3cm,low differentiation,burr sign,blood flow grade 2-3,axillary lymph node ratio,cortical thickness were all risk factors for ALNM of breast inva-sive carcinoma(OR=1.842,1.730,2.401,2.085,1.571,1.400;all P＜0.05).Conclusion:Tumor diameter,degree of differentiation,burr sign,blood flow grade,axillary lymph node ratio,axillary lymph node cortical thick-ness play a certain role in the diagnosis of ALNM in breast invasive carcinoma.关键词
