title: Preoperative chemoradiotherapy for esophageal cancer: factors associated with clinical response and postoperative complications.
abstract: BACKGROUND
  The factors associated with the clinical results of preoperative chemoradiotherapy (CRT) for esophageal cancer and its effect on postoperative complications are still unclear.
  
  
  METHODS
  The 686 patients with esophageal cancer were classified into 376 who received preoperative CRT (group I) and 310 who received surgery alone (group II).
  
  
  RESULTS
  A multivariate analysis for group I patients revealed pathologically complete response to be a favorable prognostic factor. Preoperative use of cisplatin was significantly associated with pathological effect and patients' prognosis. Both pulmonary complications and anastomotic leakage more frequently developed in group I (16.0 and 27.9%) than in group II (10.0%, p<0.05 and 16.5%, p<0.01, respectively). A multivariate analysis revealed preoperative CRT to be an independent factor of postoperative complications.
  
  
  CONCLUSIONS
  Although preoperative CRT for esophageal cancer may be associated with postoperative complications, a pathologically complete response, which is associated with a cisplatin-based regimen, is critical for improving patient prognosis.
