研究目的:

本研究旨在验证超声造影降级诊断策略的合理性,通过应用超声造影降级标准对常规超声诊断为BI-RADS 3及4类的乳腺肿块和非肿块病变进行再评估,判断其是否可以降级或升级,以减少良性病变患者不必要的穿刺活检。同时,基于研究数据构建T1期乳腺癌及导管原位癌的超声影像学诊断预测模型,为乳腺病变的精准诊断提供科学依据,优化临床诊断流程,提高诊断效率和准确性。  

Objectives of Study:

This study aims to validate the rationality of the downgrade diagnostic strategy using contrast-enhanced ultrasound (CEUS). By applying CEUS downgrade criteria to breast masses and non-mass lesions initially categorized as BI-RADS 3 and 4 on conventional ultrasound, the study seeks to reassess whether these lesions can be downgraded or upgraded, thereby reducing unnecessary biopsies in patients with benign lesions. Furthermore, based on the research data, a predictive model for the sonographic diagnosis of stage T1 breast cancer and ductal carcinoma in situ (DCIS) will be developed, providing scientific evidence for the precise diagnosis of breast lesions, optimizing the clinical diagnostic workflow, and improving diagnostic efficiency and accuracy.

药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.常规超声诊断为BI-RADS 4类,乳腺肿块最大径线<=2cm,或乳腺非肿块病变最大径线<=5cm (ACR BI-RADS指南); 2.患者在术前或穿刺前接受超声造影检查,无超声造影禁忌证,且所有患者在超声造影检查前均提供书面知情同意; 3.患者在超声和超声造影检查前未行穿刺活检或新辅助治疗; 4.患者在超声造影检查后一个月内具备穿刺活检或手术切除的病理结果; 5.对于超声造影降级为BI-RADS 3类的患者,若无穿刺活检或手术切除病理结果证实,则以DCE-MRI上BI-RADS 3类作为确诊依据,或以1年后病变在超声等影像学检查中大小无变化作为良性病变的入组依据。

Inclusion criteria

1. The conventional ultrasound diagnosis is BI-RADS category 4, with the maximum diameter of the breast mass <=2cm, or the maximum diameter of the non-mass lesion of the breast <=5cm (ACR BI-RADS guidelines); 2. Patients underwent contrast-enhanced ultrasound examination before the operation or puncture, with no contraindications to contrast-enhanced ultrasound, and all patients provided written informed consent before contrast-enhanced ultrasound examination. 3. The patient did not undergo puncture biopsy or neoadjuvant therapy before ultrasound and contrast-enhanced ultrasound examinations. 4. The patient has pathological results of puncture biopsy or surgical resection within one month after contrast-enhanced ultrasound examination. 5. For patients with contrast-enhanced ultrasound downgraded to BI-RADS class 3, if there is no pathological result of puncture biopsy or surgical resection to confirm it, BI-RADS class 3 on DCE-MRI shall be used as the basis for diagnosis, or the inclusion of benign lesions shall be based on the fact that the size of the lesion does not change in imaging examinations such as ultrasound one year later.

排除标准:

1.超声检查前已进行穿刺活检或新辅助化疗的患者; 2.未规范化采集超声图像的病例; 3.降级为BI-RADS 3类的患者在无病理或MRI检查确诊的情况下失访; 4.恶性诊断分级的患者无最终手术或穿刺结果; 5.存在超声造影检查禁忌,或不愿意签署超声造影检查知情同意书的患者; 6.超声上病变不可见的患者; 7.超声造影检查结果不确定的患者; 8.病理结果不确定的患者。

Exclusion criteria:

1.Patients who have undergone puncture biopsy or neoadjuvant chemotherapy before ultrasound examination; 2. Cases where ultrasound images were not collected in a standardized manner; 3. Patients downgraded to BI-RADS category 3 were lost to follow-up without a confirmed pathological or MRI examination. 4. Patients with malignant diagnosis grades have no final surgical or puncture results; 5. Patients who have contraindications to contrast-enhanced ultrasound examination or are unwilling to sign the informed consent form for contrast-enhanced ultrasound examination; 6. Patients whose lesions are not visible on ultrasound; 7. Patients with uncertain contrast-enhanced ultrasound examination results; 8. Patients with uncertain pathological results.
