Neoadjuvant Treatment Response in Negative Nodes Is an Important Prognosticator After Esophagectomy

Treatment-response lymph nodes detected from esophagectomy specimens in patients having undergone neoadjuvant chemotherapy or combined chemoradiation for EAC provide valuable prognostic information, particularly in patients with limited nodal disease. The current practice of considering lymph nodes lacking viable cancer cells, but with evidence of tumor necrosis, as pathologically negative likely results in understaging. Future efforts at revising the staging system for EAC should consider incorporating treatment-response lymph nodes in the analysis.
