摘　　要：目的:分析高频超声应用在乳腺癌内乳淋巴结转移患者诊断中的价值。方法:收集本院2021年5月-2023年5月这一时段内确诊医治的90例乳腺癌患者临床资料进行回顾性分析,以病理结果作为诊断内乳淋巴结的金标准,并将全体患者划分成两组,其中72例转移患者归为转移组,另18例未转移患者归为未转移组。两组患者均在术前接受了高频超声扫查,总结不同组别乳腺癌患者的内乳淋巴结声像图特征,并分析高频超声对内乳淋巴结的诊断效能。结果:内乳淋巴结声像图特征主要涵盖四种类型,即正常结构型、皮质增厚型、淋巴门结构不清型、结节状软组织增厚型。在内乳淋巴结长径、厚径、个数、结构类型方面,转移组和未转移组之间存在显著的差别,有统计学意义(P<0.05);而在长径/厚径比值、血供方面,转移组和未转移组之间不存在过大的差别,无统计学意义(P>0.05)。全部90例患者中,超声诊断出74例和病理诊断结果相符。超声诊断的灵敏度、特异度、准确度分别是88.89%(64/72)、55.56%(10/18)、82.22%(74/90)。结论:乳腺癌内乳淋巴结转移以皮质增厚和无淋巴门结构型最为多见,通常表现为多发,高频超声可以有效评估乳腺癌内乳淋巴结转移,具有较高的诊断效能。Objective:To analyze the value of high-frequency ultrasound in the diagnosis of breast cancer with internal mammary lymph node metastasis.Methods:Clinical data of 90 patients with breast cancer diagnosed and treated in our hospital from May 2021 to May 2023 were retrospectively analyzed,and all patients were divided into two groups according to the pathological results as the gold standard for the diagnosis of internal mammary lymph nodes.Among them,72 patients with metastasis were classified as the metastatic group and 18 patients without metastasis were classified as the non-metastatic group.Both groups of patients received high-frequency ultrasound scanning before surgery.The ultrasonographic characteristics of internal mammary lymph nodes in different groups of breast cancer patients were summarized,and the diagnostic efficacy of high-frequency ultrasound was analyzed.Results:(1)The ultrasonographic features of internal mammary lymph nodes mainly included four types,namely,normal structural type,cortical thickening type,unclear lymphatic portal structure type and nodular soft tissue thickening type.(2)There were significant differences in length diameter,thickness diameter,number and structural types between the metastatic and non-metastatic groups(P<0.05).There was no significant difference in the ratio of length-diameter to thick-diameter and blood supply between the metastatic group and the non-metastatic group(P>0.05).(3)Among all the 90 patients,74 cases of ultrasound diagnosis were consistent with pathological diagnosis.The sensitivity,specificity,and accuracy of ultrasonic diagnosis were 88.89%(64/72),55.56%(10/18)and 82.22%(74/90),respectively.Conclusion:Intrabreast cancer lymph node metastasis is most common with cortical thickening and no lymphatic portal structure,which are usually multiple.High-frequency ultrasound can effectively evaluate intra-breast cancer lymph node metastasis,and has a high diagnostic efficiency.
