Studies of three fields lymphadenectomy for patients with thoracic segments squamous cell carcinoma of esophagus / 肿瘤研究与临床

ABSTRACT

Objective To investigate the difference of complication incidence, death rate, quantity of lymphadeneetomy, lymphatic metastasis rate and long-term survival rate in thoracic squamons cell carcinoma of esophagus between three fields lymphadenectomy (3-FL) and traditional method. Methods Homoehronous 96 esophageal cancer patients were fractionated in two groups, 46 patients for 3-FL, the other 50 patients for traditional method. Results The average quantity of lymphadenectomy was 39.28 pieces per patient in 3-FL, and was significantly higher than 13.30 pieces per patient in traditional method (P <0.01). The rate of metastatic lymphatic nodes was 73.91%(34/46) in 3-FL patients, significantly higher than38.00%(19/50) in traditional method patients. For incidence of postoperative complications, recurrent laryngeal nerve damage and respiratory complication in 3-FL patients was significantly higher than patients in traditional method (P <0.05). The chest fluid obviously inereasod in 3-FL patients than in traditional method patients. There was significant contrast in 3-year survival rate between 3-FL patients and traditional method patients. Conclusion The there fields lymphadenectomy expand scope of lymphdenectomy effectually, accurate the staging of thoracic esophageal carcinoma. At the same time, a lot of evidence was found in raising survival rate for 3-FL. Disadvantage of 3-FL was severe surgical trauma, high incidence of complication, and a long recovery time after operation.
