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.

배경: 흉부 식도암에서 Ivor-Lewis수술이 널리 이용되어 왔으나 최근 3구역 절제술로 보다 좋은 성적들이 보고되고 있다. 식도 편평세포암 환자에서 Ivor-Lewis수술의 유용성을 알아보고자 한다. 대상 및 방법: 1994년 9월부터 2004년 8월까지 식도암으로 절제술을 받은 273명의 환자 중 편평세포암으로 다른 원발성 암이 없고 Ivor-Lewis수술로 완전절제가 가능하였던 172명을 대상으로 술 후 합병증, 조기 및 장기성적, 재발양상을 후향적인 방법으로 분석하였다. 결과: 술 후 병기는 I기 40명(23%), IIA기 48명(27%), IIB기 18명 (10%), III기 55명(33%), IVA 5명(3%), IVB 6명(4%)이었다. 수술과 관련된 사망은 172명의 환자 중 7명(4%)에서 발생하였으며 술 후 합병증은 32명(18%)에서 발생하였고 55명(32%)에서 재발하였다. 전체 환자의 5년 생존율은 48%였는데, 병기별 5년 생존율은 I기 85.6%, IIA기 47.6%, IIB기 65%, III기 22.8%, IV기 0%였다. 종양의 위치에 따른 5년 생존율은 상흉부가 26.5%로 중흉부와 하흉부 52.4%에 비해 낮았으나 통계적 유의성은 없었다. 결론: 이상의 결과로 식도 편평세포암 환자에서 Ivor-Lewis수술의 적용은 비교적 만족할 만한 결과를 얻었으며, 상흉부 식도암인 경우에는 통계적 유의성은 없었으나 중 하 흉부식도암에 비해 낮은 5년 생존율을 보여 3구역 림프절절제술로의 전환도 고려해야 할 것으로 생각된다.
