title: Wide-spread distribution of sentinel lymph nodes in esophageal cancer.
abstract: Sentinel lymph nodes are the first draining nodes that contain tumor cells. Identification of sentinel nodes may help to determine the suitable extent of lymphadenectoy. To assess the location of sentinel lymph nodes, a series of 41 patients with single and two metastatic lymph nodes who underwent esophagectomy and 3-field lymphadenectomy between 1991 and 1999 were investigated retrospectively. Only 29 (47.5%) of 61 metastatic nodes showed correspondence between the tumor site and the regional metastatic lymph nodes by routine histologic examination. In the patients with tumors in the upper and middle thoracic esophagus, metastatic lymph nodes were distributed in the cervix, mediastinum and abdomen. Although sentinel nodes were limited to the regional and adjusting compartments in 82%, nodes were found beyond the adjusting compartments in 18%. The sentinel nodes were broadly distributed depending on the location of the tumor in esophageal cancer.
