Salvage esophagectomy after definitive chemotherapy and radiotherapy for advanced esophageal cancer

Background: Although local recurrence of advanced esophageal cancer is frequent after definitive chemoradiotherapy (CRT), the clinical benefit of salvage esophagectomy has not been elucidated. Methods: We reviewed 27 patients with squamous-cell cancer who underwent esophagectomy after definitive CRT (greater than or equal to50 Gy) (salvage group) and 28 patients who underwent planned esophagectomy after neoadjuvant CRT (30 to 45 Gy) (neoadjuvant group). Results: The preoperative albumin level and vital capacity were significantly lower in the salvage group than in the neoadjuvant group. Two patients (7.4%) from the salvage group who underwent extended esophagectomy with three-field lymphadenectomy died of postoperative complications, but no deaths occurred after less-invasive surgery. There was no difference of overall postoperative survival between the salvage and neoadjuvant groups. Conclusions: The outcome of salvage esophagectomy after definitive CRT was similar to that of planned esophagectomy after neoadjuvant CRT. Less-invasive procedures might be better for salvage esophagectomy because of the high operative risk. (C) 2004 Excerpta Medica, Inc. All rights reserved.
