Application of indocyanine green in sentinel lymph node biopsy for breast cancer / 局解手术学杂志

ABSTRACT

Objective To explore the application value of indocyanine green (ICG)in sentinel lymph node biopsy(SLNB)for breast cancer.Methods A total of 160 patients with breast cancer in our hospital from January 2013 to December 2015 were analyzed,who were randomly divided into methylene blue group(n =65)and methylene blue plus ICG group(n =95).The success rate of detection,accuracy and false negative rate between two groups were compared.Results The success rate of detection and accuracy in methylene blue plus ICG group was significantly higher than thoase in methylene blue group,with statistically significant difference(P <0.05).The false negative rate of methylene blue plus ICG group was significantly lower than that of methylene blue group,with statistically significant difference (P <0.05).The number of sentinel lymph node in methylene blue plus ICG group was (2.9 ±0.9)/case which was more than (1.9 ± 0.5)/case in methylene blue group ,with statistically significant difference(P <0.05).The length of opertion of methylene blue plus ICG group was obviously shorter than that of methylene blue group.Conclusion Indocyanine green used in the sentinel lymph node detection for breast cancer can provide a reliable basis and reduce the false negative rate,who improves the level of diagnosis of breast cancer.
