Abstract: Objective To explore the value of pure wave linear array probe in the diagnosis of early breast cancer and the localization of tumor margin before breast conserving resection. Methods 200 patients with suspected early breast cancer were selected and divided into observation group （n=100） and control group （n=100）, the observation group was given pure wave linear array probe, and the control group was given ordinary linear array probe,The diagnosis, ultrasonic features and related surgical indexes of breast conserving resectionl of the two groups were observed. Results The diagnostic accuracy of early breast cancer in the observation group was 80.00%, which was significantly higher than that in the control group （P<0.05）. The ultrasonic features of breast cancer in the observation group： unclear boundary, microcalcification and the proportion of blood flow grade Ⅱ ~ Ⅲ were 62.50%, 70.00% and 73.75% respectively, which were significantly higher than those in the control group （P<0.05）; In the observation group, the proportion of cutting edge >2 cm and the rate of positive cutting edge requiring secondary dilatation were 12.50% and 8.33% respectively, which were significantly lower than those in the control group （P<0.05）. In the observation group, the preoperative prediction of tumor size and tissue resection area and postoperative anastomosis ratio were 61.76% higher than those in the control group. Conclusion The pure wave linear array probe has higher coincidence rate and sensitivity in the diagnosis of early breast cancer, and has higher diagnostic efficacy. The pure wave linear array probe has higher evaluation value for the location of surgical margin and the size and resection range of mass after mastectomy, and has higher clinical reference value.

摘要： 目的 探讨纯净波线阵探头在早期乳腺癌诊断和保乳切除术前肿块切缘定位的应用价值。方法 拟选取疑似早期乳腺癌患者 200例,随机分为观察组（n=100）和对照组（n=100）,观察组给予纯净波线阵探头检查,对照组给予普通线阵探头检查,观察两组诊断情况、超声特征及行保乳切除手术病例的相关手术指标。结果 观察组诊断早期乳腺癌的准确性为 80.00%,明显高于对照组（P<0.05）,灵敏性为73.75%,高于对照组。观察组乳腺癌超声特征：边界不清、微钙化、血流分级Ⅱ~Ⅲ比例分别为62.50%、70.00%和73.75%,明显高于对照组（P<0.05）;观察组中行保乳切除术切缘>2 cm比例及切缘阳性并需二次扩切术率分别为12.50%和8.33%,明显低于对照组（P<0.05）;观察组术前预测肿块大小及组织切除范围与术后吻合比例为61.76%,高于对照组。结论 纯净波线阵探头对早期乳腺癌诊断符合率及灵敏性较高,具备较高的诊断效能,纯净波线阵探头对保乳切除术后中手术切缘定位及肿块大小及切除范围评估价值更高,具备更高的临床参考应用价值。
