目的:评价超声引导下空心针穿刺活检技术(TCNB)在乳腺癌早期诊断和治疗中的应用价值。方法:对167例临床诊断高度怀疑为乳腺癌的患者行超声引导下空心针穿刺活检(TCNB)取部分组织进行组织学检查,结合术后病理学检查或术中快速冰冻病理学检查对比分析。结果:超声引导下空心针穿刺活检技术(TCNB)对乳腺癌的诊断敏感性94.63%,特异性100%,假阳性率0,假阴性率4.79%。结论:TCNB具有定位准确,创伤小,操作简便,可靠程度高的优点,对乳腺癌尤其是早期的诊断有较高的临床价值。
Objective: To evaluate the value of ultrasound-guided hollow needle aspiration biopsy (TCNB) in the early diagnosis and treatment of breast cancer. Methods: A total of 167 clinically diagnosed patients with breast cancer were screened by ultrasound - guided hollow needle aspiration biopsy (TCNB) for histological examination and postoperative pathological examination or rapid frozen pathological examination. Results: The diagnostic sensitivity of TCNB for diagnosis of breast cancer was 94.63%, specificity 100%, false positive rate 0 and false negative rate 4.79%. Conclusion: TCNB possesses the advantages of accurate positioning, small trauma, simple operation and high reliability. It has high clinical value for early diagnosis of breast cancer.
