【摘要】:目的: 通過(guò)回顧性分析443例BI-RADS3級(jí)乳腺病灶超聲影像學(xué)特征,探討超聲對(duì)BI-RADS3級(jí)乳腺病灶的診斷價(jià)值及影響因素。 材料與方法: (1)首先根據(jù)超聲乳腺影像報(bào)告和數(shù)據(jù)系統(tǒng)(BI-RADS-US)標(biāo)準(zhǔn)對(duì)超聲初步診斷為乳腺良性病灶(BI-RADS3級(jí)),且有明確病理結(jié)果的患者共443例,進(jìn)行回顧性分析。以病理學(xué)結(jié)果為金標(biāo)準(zhǔn),獲得BI-RADS3級(jí)乳腺病灶的陰性預(yù)測(cè)值(NPV),以及BI-RADS分級(jí)標(biāo)準(zhǔn)中良性病灶描述詞(良性征象)的NPV。(2)采用Kim等推薦的新分級(jí)標(biāo)準(zhǔn),由兩位醫(yī)師對(duì)443例BI-RADS3級(jí)乳腺病灶的超聲圖像重新判讀,獲得重新分級(jí)的結(jié)果。(3)探討B(tài)I-RADS分級(jí)及重新分級(jí)的影響因素(超聲醫(yī)師年資、患者年齡、病灶大小、病灶數(shù)目及病灶體表觸診情況)。統(tǒng)計(jì)學(xué)分析用SPSS13.0軟件進(jìn)行處理。 結(jié)果: (1)超聲BI-RADS3級(jí)的診斷效能:443枚BI-RADS3級(jí)乳腺病灶中,,432枚為良性,11枚為惡性。惡性病例包括:浸潤(rùn)性導(dǎo)管癌7枚、導(dǎo)管內(nèi)癌2枚、脂肪肉瘤1枚,中-重度不典型增生1枚。以病理結(jié)果為金標(biāo)準(zhǔn),超聲BI-RADS3乳腺病灶的NPV為97.5%。乳腺良性病灶描述詞NPV:橢圓形97.8%(405/414),圓形93.1%(27/29),平行方位97.5%(432/443),邊界清楚98.6%(358/363),邊緣窄而銳利98.1%(418/426)。 (2)根據(jù)新分級(jí)標(biāo)準(zhǔn)重新分級(jí)結(jié)果:155枚(155/443)乳腺病灶被調(diào)升至BI-RADS4級(jí),其中惡性病灶為10枚,檢出率為90.9%(10/11),良性病灶為145枚,根據(jù)BI-RADS4級(jí)的推薦處理意見(jiàn)(穿刺活檢),推算活檢假陽(yáng)性率為33.6%(145/432)。 (3)BI-RADS分級(jí)的影響因素:乳腺病灶體表觸診情況是影響B(tài)I-RADS分級(jí)的主要因素(P=0.036),惡性乳腺病灶更易被觸及。而醫(yī)師年資、患者年齡、乳腺病灶數(shù)目及大小對(duì)BI-RADS分級(jí)無(wú)明顯影響(P均>0.05)。 (4)重新分級(jí)的影響因素:患者年齡及乳腺病灶是否多發(fā)是影響重新分級(jí)的主要因素(2=51.931,P<0.001;2=9.295,P=0.002),年齡≥40歲、乳腺病灶多發(fā)的病例更可能被調(diào)升至BI-RADS4級(jí)。而醫(yī)師年資、病灶大小及病灶體表觸診情況對(duì)其重新分級(jí)無(wú)明顯影響(2=0.768,2=0.656,2=0.348,P均>0.05)。 結(jié)論: 超聲對(duì)乳腺良性病灶的篩選有很高的NPV。重新分級(jí)可以大幅度提高惡性病灶的檢出率,但將導(dǎo)致較高的穿刺假陽(yáng)性率。病灶能否觸及是影響B(tài)I-RADS分級(jí)的主要因素;颊吣挲g及乳腺病灶是否多發(fā)是影響重新分級(jí)的主要因素。
[Abstract]:Purpose :
The diagnostic value and influencing factors of ultrasound on BI - RADS3 grade breast lesions were investigated by retrospective analysis of 443 BI - RADS3 grade breast lesions .
Materials and Methods :
( 1 ) The primary diagnosis of breast benign lesions ( BI - RADS3 grade ) was first diagnosed according to the ultrasound breast image report and data system ( BI - RADS - US ) standard . Statistical analysis was performed with SPSS 13.0 software .
Results :
( 1 ) The diagnostic efficacy of ultrasound BI - RADS3 grade : 432 of 443 BI - RADS3 grade breast lesions were benign and 11 were malignant . The malignant cases included 7 lesions in invasive ductal carcinoma , 2 in ductal carcinoma , 1 in fat sarcoma , and 95.1 % ( 27 / 29 ) in circular shape and 97.5 % ( 432 / 443 ) in parallel orientation . The border was clear 98 . 6 % ( 358 / 363 ) , with a narrow margin of 98.1 % ( 418 / 426 ) .
( 2 ) According to the new grading standard re - grading results : 155 ( 155 / 443 ) breast lesions were adjusted to BI - RADS4 grade , of which the malignant lesions were 10 , the detection rate was 90.9 % ( 10 / 11 ) , the benign lesions were 145 , according to the recommended treatment opinion of BI - RADS4 ( puncture biopsy ) , the false positive rate of biopsy was 33.3 % ( 145 / 432 ) .
( 3 ) The influence factors of BI - RADS classification : the contact status of breast lesions was the main factor affecting the grading of BI - RADS ( P = 0.036 ) , and malignant breast lesions were more easily accessible , while the number and size of breast lesions were not significantly affected by physician ' s seniority , age of the patient , number and size of breast lesions ( P > 0.05 ) .
( 4 ) influencing factors of re - grading : the age of the patient and whether the lesions of breast lesions were the main factors influencing the re - grading ( 2 = 51.931 , P < 0.001 ) ;
2 = 9.295 , P = 0.002 ) , more likely to be raised to BI - RADS4 level in patients with 鈮
