[Ivor Lewis esophagectomy with two-field lymph node dissection for squamous cell carcinoma of the lower thoracic esophagus].
OBJECTIVE
Esophagectomy with local regional lymph node dissection is the main treatment for lower thoracic esophageal carcinoma. This study was to assess the clinical outcomes of Ivor Lewis esophagectomy with two-field lymph node dissection for squamous cell carcinoma of the lower thoracic esophagus.


METHODS
Clinical data of 73 patients with squamous cell carcinoma of the lower thoracic esophagus, who underwent Ivor Lewis esophagectomy with two-field lymph node dissection from Jan. 1998 to Dec. 2001, were analyzed retrospectively. Kaplan-Meier method was used for survival analysis.


RESULTS
The morbidity of postoperative complications was 15.1% with a 2.7% mortality rate. The lymph node metastasis rate was 71.2%; the metastasis rate of the upper mediastinal nodes was 17.8%. Of the 73 patients, 5 were at stage I, 35 at stage II, 32 at stage III, and 2 at stage IV. The overall 5-year survival rate was 23.3%. The 5-year survival rate was 38.1% for N0 patients and 17.3% for N1 patients (P<0.01), and was 31.2% for stage IIa patients, 27.8% for stage IIb patients, and 12.5% for stage III patients (P<0.01).


CONCLUSIONS
Ivor Lewis esophagectomy with two-field lymph node dissection for squamous cell carcinoma of the lower thoracic esophagus is a safe operation, and may increase the chances of complete resection.
