Contrast analysis on prognosis of three-field lymph node dissection and two-field lymph node dissection for upper thoracic esophageal carcinoma

Objective To explore and analyze the prognosis of three-field lymph node dissection and two-field lymph node dissection for upper thoracic esophageal carcinoma.Methods 120 patients with esophageal carcinoma who were accepted by our hospital from October 2010 to October 2011 were selected as the research subject.They were randomly and equally divided into the three-field lymph node dissection group and the two-field lymph node dissection group.Contrast the rate of lymph nodes metastasis,rate of surgical survival and complications of two groups after treatment.Results After the operation treatment,cervical lymph node and mediastinal lymph node metastasis rates in were 18.33% and 20.00% respectively,and the total incidence of complications is 30.00%.They were all lower than two-field lymph node dissection group.Meanwhile,the survival rate of three-field lymph node dissection group was 83.33% which was obviously higher than 58.33% in the two-field lymph node dissection group with a statistical significance(P 0.05).Conclusion Three-field lymph node dissection can effectively improve the prognosis and clinical curative effect in treatment of upper thoracic esophageal carcinoma.
