To determine the optimal injection path for blue dye and radiocolloid for sentinel lymph node (SLN) biopsy in early breast cancer.
A prospective randomized multicentric study was initiated to compare the peritumoral (PT) injection site to the periareolar (PA) site in 449 patients.
The detection rate of axillary SLN by lymphoscintigraphy was significantly higher (P = .03) in the PA group (85.2%) than in the PT group (73.2%). Intraoperative detection rate by blue dye and/or gamma probe was similar (99.11%) in both groups. The rate of SLN detection was somewhat higher in the PA group than in the PT group: 95.6% versus 93.8% with blue dye (P = .24) and 98.2% versus 96.0% by probe (P = .16), respectively. The number of SLNs detected by lymphoscintigraphy and by probe was significantly higher in the PA group than in the PT group, 1.5 versus 1.2 (P = .001) and 1.9 versus 1.7 (P = .02). The blue and hot concordance was 95.6% in the PA group and 91.5% in the PT group (P = .08). The mean ex vivo count of the SLN was significantly higher in the PA group than in the PT group (P < .0001).
This study strongly validates the PA injection technique given the high detection rate (99.1%) of SLN and the high concordance (95.6%) between blue dye and the radiotracer, as well as higher significant ex and in vivo counts, improving SLN probe detection.
确定早期乳腺癌前哨淋巴结(SLN)活检中蓝色染料和放射性胶体的最佳注射路径。
开展一项前瞻性随机多中心研究,比较449例患者瘤周(PT)注射部位与乳晕周围(PA)注射部位。
PA组(85.2%)腋窝SLN的淋巴闪烁显像检测率显著高于PT组(73.2%)(P = 0.03)。两组术中蓝色染料和/或γ探测器的检测率相似(99.11%)。PA组SLN的检测率略高于PT组:蓝色染料检测率分别为95.6%和93.8%(P = 0.24),探测器检测率分别为98.2%和96.0%(P = 0.16)。PA组蓝色与热点一致性为95.6%,PT组为91.5%(P = 0.08)。PA组SLN的平均体外计数显著高于PT组(P < 0.0001)。
鉴于SLN的高检测率(99.1%)、蓝色染料与放射性示踪剂之间的高一致性(95.6%)以及体内外计数更高,本研究有力地验证了PA注射技术,改善了SLN探测器检测。
