The data on 106 patients with thyroid cancer recurrence are reported. The recurrences occurred in the zone of surgery in 76.4%, beyond this zone--in 23.6%. During a 3-year period the recurrence occurred in 41.5%, from 3 to 10 years - in 44.4%, after 10 years and longer - in 14.1%. One of the main causes of the recurrence is an inadequate extent of primarily performed surgery. The recurrent tumor was detected by palpation, regional metastases were detected in 47.1%, distant--in 22.6%. A lower differentiation of the recurrent tumor was noted. The combination treatment was employed in 64% of patients. The principal surgical procedures were as follows: total thyroidectomy and subtotal thyroidectomy.
