超声引导下穿刺活检对早期乳腺癌的诊断价值

Analysis of Diagnostic Value of Ultrasound-guided Core Needle Biopsy for Early Breast Cancer

目的探讨超声引导下穿刺活检对早期乳腺癌诊断的价值。方法以128例可疑乳腺癌患者为研究对象,以术后病理确诊为金标准,分析评价超声引导下穿刺活检对早期乳腺癌的诊断结果,并与单独超声诊断结果进行比较。结果 128例可疑乳腺癌患者中,70例经术后病理确诊为早期乳腺癌患者,超声诊断为早期乳腺癌的患者有63例,超声引导下穿刺活检诊断为早期乳腺癌的患者有66例;超声引导下穿刺活检对早期乳腺癌的诊断灵敏度、特异度和准确度均高于超声诊断(P<0.05);超声引导下穿刺活检对早期乳腺癌病理分型的诊断符合率高于超声诊断(P<0.05)。超声引导穿刺活检对于病灶直径≤1 cm和1 cm<直径≤2 cm的检出率差异不具统计学意义(P>0.05),但1 cm<直径≤2 cm的检出率略高于直径≤1 cm;超声引导穿刺活检对于病灶不规则形和规则形的检出率差异不具统计学意义(P>0.05),但不规则形略高于规则形。结论超声引导下穿刺活检比单独超声检查对早期乳腺癌的诊断更具优势,能准确、尽早地了解可疑病变性质,值得临床推广。

Objective To analyze the diagnostic value of ultrasound-guided core needle biopsy for early breast cancer. Methods Suspected breast cancer patients （ 128 cases） were selected as research objects. The postoperative pathological diagnosis was as the gold standard, and the diagnosis results of early breast cancer with ultrasound-guided core needle biopsy was evaluated and compared with the results of single ultrasound. Results In 128 patients with suspected breast cancer,70 cases of were diagnosed to be early breast cancer with the postoperative pathological diagnosis ,63 cases were diagnosed to be early breast cancer with ultrasound, and 66 cases were diagnosed to be early breast cancer with ultrasound-guided core needle biopsy; The diagnostic sensitivity, specificity and accuracy of ultrasound-guided core needle biopsy for early breast cancer were higher than those of uhrasound （P 〈 0.05 ） ;The diagnostic coincidence rate of ultrasound-guided core needle biopsy for early breast cancer pathological classification was higher than that of ultrasound （P 〈 0.05） ;The detection rate difference of ultrasound-guided core needle biopsy between lesions diameter ≤1 cm and 1 cm 〈 lesions diameter≤2 cm was not statistically significant （P 〉 0.05 ） ,but the detection rate of 1 cm 〈 lesions diameter≤2 cm was slightly higher than that of lesions diameter≤1 cm; The detection rate difference of ultrasound-guided core needle biopsy between irregular shape lesions and regular shape lesions was not statistically significant （P 〉 0.05）, but the detection rate of irregular shape lesions was slightly higher than that of regular shape lesions. Conclusion Ultrasound-guided core needle biopsy has more advantage in the diagnosis of early breast cancer than single ultrasound, and it is worthy of clinical promotion to understand the nature of suspicious lesions accurately and early.
