The management of cervical lymph node metastases in well-differentiated carcinoma of the thyroid has been highly controversial. In the Department of Surgery (II), Kanazawa University Hospital, the surgical management of cervical lymph node metastases in curable well-differentiated carcinoma of the thyroid has been changed from a conservative approach to an aggressive one since 1973. In order to determine whether an aggressive approach for cervical lymph node metastases is adequate, a retrospective multivariate analysis was carried out of 218 cases of well-differentiated thyroid cancer. The patients have been followed up from 5 to 30 years. Multivariate analysis was conducted following Cox's model. As for the results, the aggressive management of cervical lymph node metastases appeared to have an impact on survival. Furthermore, age and sex were confirmed to be important prognostic factors and a partial lobectomy was confirmed to be inadequate as a type of thyroidectomy.
