The purpose of this study was to compare the lymphoscintigraphic drainage patterns of a hybrid sentinel node tracer consisting of the fluorescent dye indocyanine green (ICG) and (99m)Tc-nanocolloid with the drainage pattern of (99m)Tc-nanocolloid alone, the current standard tracer in many European countries. ⋯ The lymphatic drainage pattern of ICG-(99m)Tc-nanocolloid is identical to that of (99m)Tc-nanocolloid. This observation, together with the added value of intraoperative fluorescence guidance, warrants wider evaluation of hybrid ICG-(99m)Tc-nanocolloid as a tracer for sentinel node procedures.
