Abstract:
Objective To investigate the learning curve of contrast-enhanced ultrasonography ( CEUS) in sentinel lymph node( SLN ) of breast cancer and provide a theoretical basis for leaners to learn SLN CEUS . Methods The multi-center study of SLN CEUS in breast cancer" was planned by Sichuan Cancer Hospital . According to the uniform inclusion and exclusion criteria , 511 patients with complete clinical data and follow-up results from 9 hospitals in Multi-center were included in this study . According to the inspection time ,the patients were divided into 3 groups named as group A ( 170 patients) ,group B ( 170 patients) and group C ( 171 patients ) ,respectively . The basic clinical data ,ultrasound imaging data , intraoperative and postoperative pathological findings of all patients were recorded . With the accumulation of cases examined ,analysis was performed to find the learning curve of the SLN CEUS examination time , SLN CEUS detection rate ,SLN CEUS surface marking accuracy rate and SLN CEUS diagnosis rate ,the learning curve was analyzed . Results ① There was no statistical significant difference in patients ages , tumors sizes ,tumors locations ,SLNs numbers and LCs numbers among the three groups( all P > 0 .05) . ②As the number of cases examined increases ,the examination time was reduced gradually ,but SLN detection rate ,surface marking accuracy and SLN diagnostic coincidence rate were increased gradually( F = 151 .75 , 1 .96 ,7 .49 ,5 .50 ; P = 0 .000 ,0 .143 ,0 .001 ,0 .005 ) . Conclusions The skill of the doctor is improved gradually when learning SLN CEUS . With the number of the cases increase ,the operating time of SLN CEUS is shorted ,and the SLN detection rate ,surface marking accuracy and SLN diagnostic coincidence rate of SLN-CEUS are gradually increased . It has an important clinical significance for beginners to learn the SLN CEUS technology .
