title: A comparison of transhiatal and transthoracic resections on the prognosis in patients with squamous cell carcinoma of the esophagus.
abstract: OBJECTIVE
  The aim of this study was to investigate the long-term prognosis for squamous cell carcinoma of the esophagus treated either by the transhiatal (TH) or by the transthoracic (TT) operative approach.
  
  
  METHODS
  Two hundred and twenty-nine patients (median age: 56 (29-84) years) with squamous cell carcinoma of the esophagus underwent esophageal resection between September 1985 and April 2004. In 70 patients, the transhiatal approach and in 159, the transthoracic approach was applied. An extended mediastinal lymph-node dissection was only carried out in the course of the transthoracic technique.
  
  
  RESULTS
  Demographic data and tumor stages were comparable in both groups. A significantly better long-term survival was observed in patients with transthoracic approach for those who had undergone curative procedures (R0) (24 versus 13 months), as well as for those either without (pN0) (38 versus 14 months) or with lymph-node involvement (pN1), and for those with > or =16 (=median) dissected thoracic lymph nodes (25 versus 12 months) (p<0.05*). Patients with regional lymph-node involvement (pN1) were seen to have a significant prognostic advantage in cases with more than 16 (=median), rather than less than 16 mediastinal lymph nodes resected (p=0.045*).
  
  
  CONCLUSIONS
  The prognosis in patients with squamous cell carcinoma of the esophagus is influenced by the number of dissected mediastinal lymph nodes. Patients with regional lymph-node involvement appear to benefit from an extended lymphadenectomy, in spite of the higher rate of complications and mortality associated with this procedure.
