早期乳腺癌超声造影辅助下细针穿刺细胞学活检及标记前哨淋巴结的应用效果

Application effect of fine needle aspiration cytology and sentinel lymph nodes stain assisted by contrast-enhanced ultrasound in early breast cancer

目的探讨早期乳腺癌超声造影辅助下细针穿刺细胞学活检及标记前哨淋巴结的应用效果。方法回顾性分析首都医科大学附属北京友谊医院收治的1例早期乳腺癌患者的病例资料,采用吲哚菁绿作示踪剂的前哨淋巴结活检手术前,在超声造影辅助下进行前哨淋巴结的细针穿刺细胞学活检,并使用蓝色染料标记针吸的淋巴结。观察并比较术前穿刺和术中前哨淋巴结活检的腋窝评估效果。结果超声造影下显示了3枚前哨淋巴结,细针穿刺细胞学活检未见转移。吲哚菁绿示踪下前哨淋巴结活检出7枚淋巴结,均未见转移。术前超声造影下标记的前哨淋巴结能够在手术中识别并完全切除。结论早期乳腺癌超声造影辅助下细针穿刺细胞学活检及标记前哨淋巴结技术有可能替代传统的前哨淋巴结活检,有必要开展进一步的研究来论证此项技术。

Objective To explore the application effect of fine needle aspiration cytology and sentinel lymph nodes stain assisted by contrast-enhanced ultrasound in early breast cancer.Methods A patient with early breast cancer enrolled in Beijing Friendship Hospital,Capital Medical University received fine needle aspiration cytology assisted by contrast-enhanced ultrasonography and the sentinel lymph nodes were stained with blue dye before a standard sentinel lymph nodes biopsy traced with indocyanine green.The axillary status accessed by these two methods were compared.Results Three sentinel lymph nodes were found and aspirated assisted by contrast-enhanced ultrasonography.Seven sentinel lymph nodes were obtained in sentinel lymph nodes biopsy surgery.All of these sentinel lymph nodes were negative.The stained sentinel lymph nodes could be recognized and dissected in open lymph nodes biopsy surgery.Conclusions Fine needle aspiration cytology assisted by contrast-enhanced ultrasonography could be a substitute for open sentinel lymph nodes biopsy.More related researches should be carry out to further compare these two methods.
