摘要
目的·研究不同浓度的吲哚菁绿(ICG)在前哨淋巴结活检(SLNB)中皮下淋巴管及淋巴结的显影情况,寻找最佳浓度以提高SLNB的成功率。方法·选择2015年1月—2017年5月临床腋窝淋巴结阴性的原发性乳腺癌患者339例,采用ICG和亚甲蓝双示踪法行SLNB。浓度为1.25 mg/mL的ICG原液,稀释至不同浓度,注射体积1 mL;亚甲蓝注射1 mL(10 mg/mL)。记录注射不同浓度的ICG后,皮下淋巴管、淋巴结的显影情况及SLNB成功率。结果·ICG浓度对淋巴管及淋巴结显影率和最终活检成功率有影响(P=0.001)。在肿瘤位于乳房非外上象限(穿刺活检或手术切除活检)及肿瘤位于外上象限未行切除活检(穿刺活检)组中,达到80%的皮下淋巴管显影率的ICG浓度为0.723 mg/mL(95%CI为0.595~0.915 mg/mL)。该浓度范围在这组患者中皮下淋巴结显影率为28%~53%,SLNB成功率为88%~92%;在肿瘤位于外上象限且已切除组中,皮下淋巴管和淋巴结显影率分别为50%~69%和20%~42%,SLNB成功率为76%~81%。2组的皮下淋巴管显影率差异有统计学意义(P=0.014),淋巴结显影及SLNB成功率差异无统计学意义(P=0.628,P=0.232)。结论·ICG荧光法+亚甲蓝染色法的双示踪法行SLNB简单易行且活检成功率高,ICG最佳浓度为0.723 mg/mL,可提高淋巴管及淋巴结的显影率。
Objective·To study the imaging of subcutaneous lymph-vessels and lymph-nodes in sentinel lymph node biopsy （SLNB） with different concentrations of indocyanine green （ICG）, and to find the best concentration to improve the success rate of SLNB. Methods·A total of 339 primary breast cancer patients with clinical negative axillary lymph node were enrolled in the study. Double tracer method [ICG and methylene blue （10 mg/mL）] was used for sentinel lymph node biopsy. 1.25 mg/mL ICG was diluted to difference concentration. The injection volume was 1 mL for ICG and 1 mL for methylene blue. The imaging of subcutaneous lymph-vessels and lymph-nodes and the success rate of SLNB were recorded after injection of different concentrations of ICG. Results·The concentration of ICG had significant effect on lymph-vessels and lymph-nodes imaging rate and SLNB success rate （P=0.001）. In the group that breast tumors not located in the external upper quadrant （needle biopsy or excisional biopsy） and tumor located in the external upper quadrant without excisional biopsy （needle biopsy）, concentration of ICG reached 80% subcutaneous lymph-vessels imaging rate is 0.723 mg/mL （95% CI 0.595-0.915 mg/mL）. In this group, in this concentration range, the imaging rate of subcutaneous lymph node was 28%-53%, and the success rate of SLNB was 88%-92%. In the group that breast tumors located in the external upper quadrant and had been resected, the imaging rate of subcutaneous lymph-vessels and lymph-nodes was 50%-69% and 20%-42%, respectively, and the success rate of SLNB was 76%-81%. The difference of subcutaneous lymph-vessels imaging rate between two groups was statistically significant （P=0.014）, but the difference of lymph-nodes imaging rate and SLNB success rate had no significance （P=0.628, P=0.232）. Conclusion·Using double tracer （ICG and methylene blue） in SLNB is simple and feasible. The best concentration of ICG is 0.723 mg/mL, which can improve the imaging rate of lymph nodes and lymph node
