Lymph nodes metastases in differentiated thyroid cancer--prognostic value and surgical results with 430 patients for 30 years period (1980-2010).

: In this we review 430 differentiated thyroid cancer patients underwent surgery for 30 years period since 1980 to December 2009. The stage of disease was T1-3.Na-b.Mo(TNM). Papillary thyroid cancer patients were 77.2% and folicular thyroid cancer--22.8%. The regional lymph nodes metastases distribution were analyzed according to the age, sex, of the patients and tumor histology. Preoperatively,clinically involved were neck nodes in 35 patients 8.3%--26 patients with PTC and in 9 patients with FTC. Surgical procedures for low-risk group of patients were variable from lobectomy and istmusectomy to near total thyroidectomy and modified radical lymph node dissections of the neck and patients in high risk group underwent total thyroidectomy and radiojodine therapy. The level of regional recurrences was 1.7 folds higher in patients treated by total thyroidectomy and radiotherapy J131.
