Sentinel Node Biopsy by Indocyanine Green Retention Fluorescence Detection for Inguinal Lymph Node Staging of Anal Cancer: Preliminary Experience

Background There is some evidence that sentinel lymph node (SLN) biopsy guided by dye injection and/or radioisotopes can improve staging of inguinal lymph nodes (LNs) in anal cancer. This study was performed to investigate the feasibility of fluorescence detection of SLN and lymphatic mapping in anal cancer.
