Abstract

Objective: Sentinel lymph node (SLN) mapping for endometrial (EC) and cervical cancers (CC) is a current technique that could provide benefits over traditional lymphadenectomy. Near-infrared (NIR) fluorescence imaging is a promising technique to perform this procedure. We conducted a systematic review of the evidence regarding the technique and the effectiveness of indocyanine green (ICG) during SLN biopsy, using robotic and laparoscopic assisted surgery and laparotomy.

Materials and methods: We conducted a computer literature search for published English language studies in humans using PubMed since January 2010 up to May 2015. The initial search came up with 17 articles, of which 10 articles used ICG as tracer in SLN biopsy in EC and CC.

Results: 422 patients were included in 10 studies, ranging from 1 to 227 patients. The main surgical approach used in ICG SLN biopsy was robotic-assisted surgery in 368 patients. Laparotomy was performed in 39 patients and laparoscopy in 15. The detection rate in SLN mapping using ICG ranged from 78% to 100% for cervical injection and from 33% to 100% for hysteroscopic injection. Sensitivity and negative predictive value (NPV) vary from 50% to 100% and 88% to 100%, respectively. The most common site of injection was the cervix (two quadrants); this technique is correlated with a high detection rate (ranging from 78% to 95%). The cervical submucosal and stromal injections were the most frequent sites used. No complications related to ICG administration were described.

Conclusions: NIR fluorescence imaging using ICG is performed in robotic-assisted surgery in laparoscopy and in laparotomy, being a feasible, safe, time-efficient and seemingly reliable method for lymphatic mapping in early stage of CC and EC. Although it has promising results in SLN mapping, randomized studies, with larger patient samples, are needed.
