Sentinel Lymph Node Biopsy Is Feasible in Cervical Cancer Laparoscopic Surgery: A Single-Center Retrospective Cohort Study

Table 2

Sentinel lymph node detection rates according to different tracer methods.

Tracer	N	Overall detection rate (n, %)	χ^2	value	Bilateral detection rate (n, %)	χ^2	value
ICG	93	82, 88.2	2.702	0.262	61, 65.6	8.537	0.014
CNPs	92	77, 83.7			50, 54.3
ICG + CNPs	85	78, 91.8			64, 75.3

The 93 cases of ICG included 85 with combined tracers and 8 with ICG alone. The 92 cases of CNPs included 85 with combined tracers and 7 with CNPs alone. ICG detected at least one SLN in 82 patients including 75 with combined tracers and 7 with ICG alone. ICG detected bilateral SLNs in 61 patients including 55 with combined tracers and 6 with ICG alone. CNPs detected at least one SLN in 77 patients including 70 with combined tracers and 7 with CNPs alone. CNPs detected bilateral SLNs in 50 patients including 46 with combined tracers and 4 with CNPs alone. CNPs versus ICG + CNPs, . SLN, sentinel lymph node; ICG, indocyanine green; CNPs, carbon nanoparticles.
