Abstract

BACKGROUND: The Ivor-Lewis operation has been widely applied for treating thoracic esophageal cancer, but more acceptable results from three-field lymph node dissection have recently been reported. In this study the efficacy of the Ivor-Lewis operation was evaluated. MATERIAL AND METHOD: Among the 273 patients, who underwent operation for esophageal cancer between September 1994 and August 2004, we retrospectively studied 172 patients with esophageal squamous cell carcinoma and who had no other primary cancer and who underwent complete resection with an Ivor-Lewis operation. The postoperative complications, the short and long-term survival and the recurrence patterns were analyzed. RESULT: The postoperative staging was as follows: stage I in 40 cases, IIA in 48 cases, IIB in 18 cases, III in 55 cases, IVA in 5 cases and IVB in 6 cases. The operative mortality rate was 4% (7 of 172 pts). Postoperative complication occurred in 32 patients (18%) and tumor recurred in 55 patients (32%). The overall 5-year survival rate was 48%; it was 85.6% in stage I patients, 47.6% in IIA patients, 65% in IIB patients, 22.8% in III patients and 0% for those in IV (p<0.05). The 5-year survival rate according to the location of esophageal cancer was 26.5% for patients with tumor in the upper 1/3 of the esophagus and 52.4% for patients with tumor in the mid and lower 1/3 (p>0.05).
CONCLUSION
The Ivor-Lewis operation is an acceptable surgical procedure for thoracic esophageal squamous cell carcinoma. Yet it is necessary to consider other surgical procedures, and especially three-field lymph node dissection for treating upper 1/3 esophageal cancer.
