METHODS: All mammogram reports with the word \"distortion\" were assessed between April 2020 and October 2022. There were 458 mammograms with the word \"distortion.\" After excluding mammograms with no distortion (n = 128), post-surgical distortion (n = 173), distortion with mass (n = 33), and unchanged distortion (n = 14), there were 111 patients with pure distortion. Correlation with histopathology was obtained where possible. All patients were followed for a minimum of 2 years.
RESULTS: Forty-two out of 111 patients (37.84%) with AD had a normal ultrasound (US) and were discharged. Fifty-five (49.5%) patients had sonographic correlation corresponding to the distortion, leading to US-guided biopsy. Thirteen (23.6%) had tomosynthesis-guided biopsy, and one had a skin biopsy. The PPV for malignancy was 42.34%. Malignancy diagnoses were higher with US-guided biopsies than tomosynthesis-guided biopsies, 78.1% and 30%, respectively.
CONCLUSIONS: With a total malignancy rate of 42.34%, DBT-detected AD has a high enough PPV for malignancy to justify selective tissue sampling if a sonographic correlate is present or with suspicious mammograms. The chances of malignancy are higher when a sonographic correlate corresponding to AD is present.
CONCLUSIONS: AD on DBT/synthesized mammograms views in symptomatic breast clinic patients justifies selective sampling.
方法:在2020年4月至2022年10月期间评估了所有带有“变形”字样的乳房X线照片报告。有458张乳房X线照片,上面写着“变形”。排除乳房X线照片后,没有变形(n=128),术后变形(n=173),质量失真(n=33),和不变的失真(n=14),有111例纯变形患者。在可能的情况下获得与组织病理学的相关性。所有患者随访至少两年。
结果:111例AD患者中有42例(37.84%)的超声(US)正常并出院。55例(49.5%)患者有与畸变相对应的超声相关性,导致美国引导活检。13例(23.6%)进行断层合成引导活检,还有一个做了皮肤活检.恶性肿瘤的阳性预测值(PPV)为42.34%。美国引导活检的恶性诊断高于断层合成引导活检。78.1%和30%,分别。
结论:总恶性率为42.34%,DBT检测到的建筑扭曲具有足够高的PPV,用于恶性肿瘤,如果存在超声相关性或可疑的乳房X线照片,则可以进行选择性组织采样。当存在对应于AD的超声相关性时,恶性肿瘤的机会更高。
结论:症状性乳腺门诊患者DBT/SM观点的结构失真证明了选择性采样的合理性。
