Research Of Ultrasound-guided Core Needle Biopsy In The Diagnosis Of Breast Lesions

Objective:In clinical practice,clinical manifestations,imaging and pathological results together influence the decision making of treatment for breast lesions.At present,breast cancer has become the largest new malignant tumor in the world.Early detection and early treatment of breast lesions greatly affect the quality of life and prognosis of patients.Ultrasound-guided hollow needle biopsy is a common method of sampling.Due to the differences in the methods of obtaining lesions,the energy efficiency of imaging evaluation and the level of pathological diagnosis,the results of puncture pathology and surgical pathology are still different,which affects the subsequent treatment.This study aims to through a large sample of tubular needle biopsy pathological paraffin pathology group compared with surgery,to discuss the clinical US CNB in different BI-RADS classification of the diagnostic value of breast lesions as well as the possible factors that influence the accuracy of insufficient found in the work and explore countermeasures available now,thinking and decision making reference for further diagnosis and treatment.Methods:Choose between January 2019 and June 2020 in Shanxi Medical University NO.1Hospital of ultrasound mammary gland lesions BI-RADS classification for 3 ～ 5,and in Shanxi Medical University NO.1 Hospital of ultrasound guided biopsy after surgical treatment of case data,statistical different ultrasonic diagnosis of benign breast lesions and malignant breast lesions constitute ratio and the accuracy of the consistency of benign pathological results and malignant pathological results,and may cause pathology underestimate factors of Ci-square test,analysis of the risk factors of undervalued.Results:All between January 2019 and June 2020 in Shanxi Medical University NO.1Hospital of ultrasound mammary gland lesions BI-RADS classification for 3 ～ 5,and in Shanxi Medical University NO.1 Hospital of ultrasound guided biopsy after surgical treatment of cases,BI-RADS classification for 3～4 a,4 b,4 c～5 accuracy were 98.89%,97.06% and 95.95%,respectively for malignant lesions pathologic undervalued rate was21.43%(3/14),5.71%(2/35),4.35%(3/69).For breast lesions < 10 mm in diameter,the consistency of puncture biopsy and surgical paraffin pathology is quite consistent,and the diagnosis results are reliable.In the diagnosis of intraductal papilloma,age <40years old and mass diameter ≥15mm are risk factors for possible pathological underestimation;In atypical hyperplasia,irregular morphology and multiple spotty calcifications are risk factors for pathological underestimation.In ductal carcinoma in situ,the presence of microcalcification in the lesion and the hard texture of the mass shown on elastography are risk factors for pathological undervaluation.Conclusion:1.Ultrasound-guided puncture biopsy has small trauma,simple operation and high accuracy in pathological diagnosis.It has high accuracy in lesions with different BI RADS grades and diameter < 10 mm,and is highly consistent with the pathological results of surgical resection,which is an accurate,safe and effective method for diagnosis of breast lesions.2.The undervaluation rate of US CNB in intraductal papilloma,atypical hyperplasia,lobular carcinoma in situ and ductal carcinoma in situ is relatively high,and further surgical biopsy is needed to confirm the diagnosis when the pathological findings are above.
