摘　　要：目的探讨磁共振多序列成像检查对指导三阴性乳腺癌(TNBC)新辅助化疗后保乳手术开展的价值。方法选取2018年6月—2023年6月收治的98例TNBC患者(均接受新辅助化疗),通过随机数字表法分为对照组和观察组,每组各49例。对照组采取超声体表定位法标记肿瘤范围,观察组根据磁共振多序列成像检查结果勾画肿瘤边界,对两组患者均进行保乳手术,比较不同影像技术对开展保乳手术的应用价值。结果观察组术前评估肿瘤最大径、肿瘤/乳房体积比均小于对照组(P<0.01,P<0.05),与实际手术切除肿瘤体积吻合率、切缘阴性率高于对照组(均P<0.05);观察组手术时间、并发症发生率与对照组比较无差异(P>0.05)。结论磁共振多序列成像检查对指导TNBC新辅助化疗后开展保乳手术具有重要价值,能精准提供切除范围,且并发症发生率较低,值得推广。Objective To investigate the value of magnetic resonance multisequence imaging in guiding breast conserving surgery after neoadjuvant chemotherapy for triple negative breast cancer(TNBC).Methods A total of 98 patients with TNBC admitted to Sanming Second Hospital in Fujian Province from June 2018 to June 2023(all receiving neoadjuvant chemotherapy)were selected and randomly divided into a control group and an observation group by random number method.Among them,49 patients underwent ultrasound body surface localization and were included in the control group,and the other 49 patients underwent magnetic resonance multisequence imaging and were included in the observation group.Both groups underwent breast conserving surgery to compare the application value of different imaging techniques for the surgery.Results The preoperative estimated maximum diameter of the tumor and the tumor/breast volume in the observation group were smaller than those in the control group(P<0.01,P<0.05),and the coincidence rate with the actual surgical resection of the tumor volume and the negative margin rate in the observation group were higher than those in the control group(P<0.05).There was no difference in surgical time and incidence of complications between the observation group and the control group(P>0.05).Conclusion Magnetic resonance multisequence imaging has an important value in guiding breast conserving surgery in TNBC patients after neoadjuvant chemotherapy,providing an accurate resection range,and having a low incidence of complications,which is worth promoting.
