| Objective : To investigate the different characteristics of the coronal plane of Automated Breast Volume Scanner(ABVS)combined with pathological classification,grading and prognosis in the diagnosis of breast cancer.Materials and Methods:A total of 269 patients with 300 lesions,all of whom were female(26-86 years old),were selected from our hospital from January 2016 to April2017 with breast cancer resection and preoperative ABVS breast cancer.The mean age was(52.77 ± 8.54)years old and the size of the lesion was(5-50)mm,with an average of(21.0 ± 10.2)mm.Due to probe size limitations,lesions> 50 mm in diameter were not included in the study.All lesions were surgically clear pathological diagnosis.ABVS is a Siemens Acuson S2000 ABVS ultrasonic diagnostic instrument manufactured by Siemens,equipped with high-frequency volume high-frequency probe14L5 BV,a frequency of 5-14 MHZ.First of all,in order to fully expose the examination site,the patient supine position,hands on the move,according to the size of each patient's breast to adjust the probe preset parameters.Second,in order to make the scan range more comprehensive,in the image acquisition,you should scan in addition to the medial median and lateral position.Finally,the obtained images were transmitted to the ABVS image processing system for three-dimensional reconstruction to obtain sagittal and coronal images,and each image was analyzed on-machine.Analysis of the lesion ABVS coronal surface in the pathological type,pathological stage and prognostic indicators of diagnostic value.The three-dimensional echocardiographic features of the corpuscles: "pooled sign" for the first group,"burr / angulation" for the second group,"border is unclear" for the third group.The diagnostic accuracy and pathological type,pathological grade,tumor size and lymph node metastasis of benign and malignant tumors were recorded and studied.Results:1.Among the three groups,there were 85 lesions in the first group,144 lesions in the second group and 71 lesions in the third group;The numbers and percentage of malignant lesions in the three groups were 83(97.6%),109(75.7%),40(56.3%).The accuracy rate of diagnosis of malignant tumors in group 3 is group 1> group 2> group3.The difference was statistically significant(p <0.01).2.The number and percentage of pathological findings in malignant lesions as invasive carcinomas were 75(90.4%),89(81.7%),21(52.5%)in the three groups;The number and percentage of non-invasive cancer were 8(9.6%),20(18.3%),19(47.5%).In the diagnosis of invasive cancer accuracy: group 1> group 2> group 3.After statistical analysis,the diagnostic accuracy of the difference between the three groups was statistically significant(p<0.01).3.In the pathological staging of invasive carcinoma,the pathological grade of 75 lesions in group 1 was in grads II and III,with the numbers and percentages being 45(60%)and 30(40%),respectively;Among the 89 lesions in group 2,the number of lesions and the percentage of 86 lesions were 52(58.4%)and 34(38.2%)in grads II and III;In group 3,21 lesions of 19 pathological grading in the II and III,the number and percentage were detected in 12(57.1%)and7(33.3%).The detection rates of grade II and III in the pathological grading of invasive carcinoma were as follows: group 1>group 2> group 3;the differences were statistically significant(p <0.05).4.In lymph node metastasis,the number and percentage of lymph node metastasis in83 malignant lesions of Group 1 were 45(54.2%).The number and proportion of lymph node metastasis in 109 malignant lesions in group 2 were 39(35.8%).In group 3,the number and percentage of lymph node metastases in 40 malignant lesions were 10 (25%).It is easy to see that in the lymph node metastasis status,the detection rate group 1> group 2> group 3.After statistical analysis,the difference between the three groups was statistically significant(p <0.01).5.In 232 cases of breast cancer,there were 114 lesions with diameter d?20 and 118 lesions with diameter?20?50.The number of small and medium breast cancer in the three groups were 48(57.8%),35(42.2 %;53(48.6%),56(51.4%);13(32.5%),27(67.5%).The number of lesions and the percentage of lesions in the three groups were48(57.8%),35(42.2 %;53(48.6%),56(51.4%);13(32.5%),27(67.5%).In the diagnosis of small breast cance,the percentage of the three is groups 1> group 2>group 3;According to statistical analysis,the difference between the three groups was statistically significant(p <0.05).Conclusions:1.In the diagnostic accuracy of breast cancer,ABVS coronal plane unique characteristic "convergence" was significantly higher than the "burr or angulation" signs and "borderless" signs.2.The "pooled sign" has unique advantages in the diagnostic accuracy of invasive cancers and is also superior to the "burr or angulation" sign and the "ill-defined" signs.3."Collection sign" outperformed the "burr or angulation" sign and the "ill-defined" signs in pathological grading and lymph node metastases.4.The diameter of breast cancer less than 20 mm more likely to "pool sign." 5.ABVS coronal characteristic performance "pooled" on the prognosis of breast cancer have important reference value. |
