Ultrasonic manifestations of breast encapsulated papillary carcinoma:Comparison with breast invasive breast carcinoma of non-special type
Objective To observe ultrasonic manifestations of breast encapsulated papillary carcinoma(EPC)in comparison with breast invasive breast carcinoma of no special type(IBC-NST).Methods A total of 14 cases with pathologically confirmed EPC(EPC group)were retrospectively collected,and 28 cases of IBC-NST(IBC-NST group)with matched age,sex and time period were enrolled at the ratio of 1:2.The ultrasonic findings were compared between groups,and the ultrasound-related independent predictors for EPC were screened using multivariate logistic regression analysis.The coincidence rate of biopsy pathology to postoperative pathology,as well as the axillary lymph node metastasis rate indicated by postoperative pathology were compared between groups.Results There were significant differences of lesions'transverse diameter,longitudinal diameter,internal echo,posterior echo and axillary lymph nodes enlargement or not between groups(all P＜0.05).Mixed internal echo was an independent risk factor,while posterior attenuation was an independent protective factor for EPC(both P＜0.05).Both the coincidence rate of biopsy pathology to postoperative pathology and axillary lymph node metastasis rate showed by postoperative pathology in EPC group were lower than those in IBC-NST group(both P＜0.05).Conclusion Compared with IBC-NST,EPC ultrasound often showed relatively larger lesions,mixed internal echo(cystic-solid),enhanced or not changed posterior echo and fewer axillary lymph node metastases.
