ABSTRACT
Objective:To explore clinical application value of color Doppler ultrasound (CDU) assigned to diagnose triple-negative breast cancer (TNBC) and axillary lymph node metastasis (ALNM).Methods:A retrospectively analyzed of proved of clinical data on the 863 patients breast cancer in women by CDU inspection,operation and pathology.According results will be divided into TNBC group and non negative breast cancer (NTNBC) group via clinical pathological and immunohistochemical detection.Using multi-factor unconditioned Logistic regression analysis the CDU supposed the diagnosis and the correlation of TNBC.Results:The coincidence rate of CDU and pathological diagnosis was 90.96％ (785/863),78 cases (9.04％) remove breast masses,105 patients TNBC group and NTNBC group 680 patients.The mass circular or elliptic (48.57％ vsl0.70 ％),the tumor maximum diameter 5.0 cm (21.90％ vs 15.30 ％),micro calcifications (87.62％ vs 74.12 ％),state clearly (56.19％ vs 41.47 ％),no burr edge character (74.29％ vs 41.62 ％),peripheral hyperechoic halo ring (74.29％ vs46.76 ％),rear echo attenuation (72.38％ vs 46.76 ％),no ALNM (61.90％ vs 37.35％) comparing the two groups exists significant difference (P＜ 0.05),while the mass number,and vertical and horizontal diameter ratio,degree of echo,echo distribution and blood flow classification comparing the two groups were no significant difference (P＞ 0.05).The CDU fu points ＞ 10 divided into NTNBC and pathological coincidence rate 93.93％ (680/724),8 ～ 10 points TNBC suspected diagnosis coincidence rate 11.51％ (16/139),＜ 8 points TNBC tendency diagnosis coincidence rate 64.03％ (89/139),TNBC total diagnostic coincidence rate was 75.54％ (105/139).In CDU diagnosed 785 cases of breast cancer,the ALN enlargement in 319 cases (40.64％),with TNBC group was 61.90％ (65/105),NTNBC group was 37.35％ (254/680).Logistic regression analysis results:tumor assumes the circular or elliptic,edge without burr,peripheral hyperechoic halo ring,rear echo attenuation and ALNM with TNBC has certain correlation (P＜0.05).Conclusion:The seemingly benign breast diseases and axillary lymph node enlargement,the CDU,supposed less than 8 points,age 50 or less or not at the same time,menopause or having a history of breast cancer susceptibility to family,important reference index,clinical value has high of CDU diagnostic of TNBC and ALNM.
