The goal of this pilot study was to compare three tracers for the detection of sentinel nodes in patients with lung cancer. Forty-eight patients with clinical N0 non-small cell lung cancer were enrolled. Indocyanine green (n=16) or isosulfan blue (n=18) was injected around the tumor intraoperatively, or technetium tin colloid was injected preoperatively under CT guidance (n=14). Sentinel nodes were detected in 6.3% of patients injected with indocyanine green, 50.0% of patients injected with isosulfan blue, and 64.3% of patients injected with technetium tin colloid. The detection rate achieved with indocyanine green was significantly lower than with the other two tracers. A false-negative sentinel node was seen in 1 patient using isosulfan blue. Both isosulfan blue and technetium tin colloid seem to be suitable for intraoperative sentinel node mapping in patients with lung cancer.
