CORRELATION ANALYSIS BETWEEN AXILLARY LYMPH NODE METASTASIS DIAGNOSED BY ULTRASOUNDOF BOTH BREASTSAND MASS INDEXES OF BREAST CANCER PATIENTS

The purpose was to explore correlation between axillary lymph node metastasis diagnosed with ultrasound of both breasts and mass indexes of breast cancer patients. Methods. 160 breast cancer patients treated in our hospital(2017.1-2019.1) were chosen. Axillary lymph node contrast-enhanced ultrasonography (CEUS) was used to detect lymph node metastasis,and pathological examination was performed to confirm the metastasis.Breast ultrasound was applied to find breast masses in breast cancer patients.Analysis was conducted on the the correlation between axillary lymph node metastasis and mass ultrasound signs in breast cancer patients. Results. (1) Among 160 breast cancer patients, 90 had axillary lymph node metastasis, accounting for 56.25%, and 70 had normal axillary lymph nodes, accounting for 43.75%. The overall accuracy of axillary lymph nodeCEUS examination was 97.14%, which was not significantly different fromthat of pathological examination (P>0.05). (2) The detection rate of mass ultrasound signs was obviously higher compared with normal axillary lymph nodes, including unclear boundary, hyperechoic halo, combination with microcalcification, abundant blood flow signals and mass diameter (≥2cm). The maximum mass diameter of patients with axillary lymph node metastasis was also higher compared with normalnodes. But the resistance index was lower compared with normal nodes, with significant differences (P<0.05). (3) Cox multivariate analysis found that hyperechoic halo, microcalcification, blood flow signals, maximum mass diameter, resistance index and boundary were independent factors affecting axillary lymph node metastasis. Conclusion. Axillary lymph node metastasis diagnosed by ultrasound of both breasts is correlated with the mass indexes of breast cancer patients, and the correlation offers a reference for prediction and diagnosis of axillary lymph node metastasis, which is worthy of further study.
