Bài viết trình bày đánh giá giá trị chẩn đoán của các dấu hiệu nghi ngờ ác tính trên siêu âm vú. Phương pháp: 268 bệnh nhân (BN) có khối u vú với các dấu hiệu nghi ngờ ác tính phát hiện trên siêu âm độ tuổi từ 12 tuổi đến 75 tuổi, độ tuổi trung bình là 42,1. | ĐÁNH GIÁ GIÁ TRỊ CHẨN ĐOÁN CỦA CÁC NGHIÊN CỨU KHOA HỌC DẤU HIỆU NGHI NGỜ ÁC TÍNH TRÊN SCIENTIFIC RESEARCH SIÊU ÂM VÚ Diagnostic value of suspected malignancy signs on breast ultrasound Phạm Thị Phương Nguyễn Thu Hương Nguyễn Công Tiến Phạm Minh Thông SUMMARY Objective To evaluate the diagnostic value of suspected malignancy signs on breast ultrasound. Methods patients who have the solid mass in breasts underwent ultrasound examination they have at least one of eight signs of suspected malignancy on breast ultrasound and performed the ultrasound guided needle biopsy of these mass at Bach Mai Hospital from July 2019 to July 2020 were investigated. Results 268 patients have breast tumors with signs of suspected malignancy detected on ultrasound mean age 42 1 years range 12 to 75 . There were 97 breast cancer patients accounted for 36 2 including 84.5 of patients over 40 years old. Cancer lesions are mainly at the upper - outer quadrant position accounting for 58 8 . The sensitivity specificity PPV and the OR value in regression analysis of suspected malignancies signs respectively spiculation and or thick hyperechoic halo 67 01 97 07 92 87 67 44 irregular shape with angular margins 89 69 and 70 76 63 5 21 05 retrotumoral acoustic shadowing 18 56 and 98 83 90 19 25 hypoechoic echo pattern 96.91 and 7.02 37.15 orientation not parallel includes round solid nodules with round shape 57 73 and 84.21 67 47 7 29 duct changes - enlarged ducts within surrounding tissues 24 74 and 95.91 77 42 7 7 microlobulations 38 14 and 90.06 68 52 5 59 microcalcifications within or outside a mass 49 48 and 89 47 72 73 8 33 . Conclusion The signs of suspected malignancy on breast ultrasound have high diagnostic value in diagnosing breast cancer especially the signs of spiculation and or thick hyperechoic halo irregular shape with angular margins and retrotumoral acoustic shadowing. In which spiculation and or thick hyperechoic halo is the sign with the highest UTV diagnostic value .
