The authors evaluated the efficacy of extended radical (three-field) lymphadenectomy for esophageal cancer compared with less radical (two-field) lymphadenectomy.Study Subjects and Analytic Methods
The mortality and morbidity rates, postoperative courses, and survival rates were compared between 63 patients who underwent three-field lymph node dissection and 65 who underwent two-field lymph node dissection at Kurume University Hospital from 1986 to 1991. Long-term quality of life after surgery was compared between 37 patients who underwent three-field dissection and 35 who underwent two-field dissection from 1980 to 1991.Results
Three-field dissection resulted in better survival for patients with positive lymph node metastasis from a carcinoma in the upper thoracic or midthoracic esophagus compared with two-field dissection. The mortality rates, postoperative courses and quality of life were the same for both procedures.Conclusions
Three-field dissection is preferred for upper thoracic or midthoracic esophageal cancer because of improved survival, acceptable mortality and morbidity rates, and good postoperative course and quality of life.
