AN ASSESSMENT OF EXTENDED LYMPHADENECTOMY INCLUDING CERVICAL NODE DISSECTION FOR CANCER OF THE THORACIC ESOPHAGUS

An extended lymphadenectomy including cervical node dissection is one of the most difficult operations, therefore its merits and demerits should be assessed in order to evaluate whether it has the significance of extended radical operation or not.
Extended lymphadenectomies including cervical node dissection became to be the standard procedures of lymphadenectomy for cases with cancer of the thoracic esophagus from 1986, and were carried out in 42 cases. Survival rates, disease free survival rates, sites of recurrences and incidences of postoperative complications were compared with the of cases with conventional lymphadenectomy excluding cervical node dissection. Concerning over all survival rates, no significant differences were observed between extended and conventional groups. However only in cases of stage 0 I II, significant difference in survival rates were observed between two groups. Therefore based on our experience, the merit of extended lymphadenectomy was observed only in stage 0 I II cases which had no lymph node metastasis. Concerning the incidence of postoperative complicatins, no significant differences were observed between two groups, therefore the significance of proceeding extended lymphadenectomy was confirmed.
