Table 2 Comparison of sentinel lymph node biopsy results between the two groups

From: Preliminary study of contrast-enhanced ultrasound in combination with blue dye vs. indocyanine green fluorescence, in combination with blue dye for sentinel lymph node biopsy in breast cancer

  CEUS + blue dye (n = 127) ICG + blue dye (n = 316) P
Identification rate of SLNs, n (%) 125/127 (98.4) 310/316 (98.1) 0.814
Number of SLNs identified per patient, mean ± SD 3.06 ± 1.33 3.12 ± 1.31 0.659
SLN metastasis, n (%) 13/127 (10.2) 36/316 (11.4) 0.726
Time consumption of SLN localization in the OR (min) 11.01 ± 3.56 12.10 ± 3.21 0.105
