Essential approaches to the regional metastasizing rubric in TNM system were analyzed. Basing on summary of the results of 466 operations, performed for the thyroid gland cancer including intervention on cervical lymph nodes, the subgroup N alteration in international classification TNM was proposed, permitting to reflect individual clinical situation full to the brim and to achieve significant practical gain in further management of patient. The grading proposed corresponds to general principle, according to which every subsequent rubric must determine more severe affection without combining several types of affection in individual patient.

Results of reoperation for the thyroid gland cancer (THGC) were analyzed in 189 patients for 1981-2001 yrs period. Majority of patients were primarily operated in other hospitals of Ukraine. Thorough characteristic of the cancer forms, terms of reoperation performance, results of histological investigation of the tumor are adduced. Large frequency (41.2%) of the operation performance for THGC recurrences in term up to one years after performance of primary intervention trusts the necessity of operative intervention performance on thyroid gland (THG) in specialized centre by experienced surgeons. Absence of malignant growth in the THG stump while performance of definitive thyroidectomy in 60% of observations is not the cause to reject of doing it because the conduction of radioiodine therapy is possible after complete excision of the THG tissue. Examination and ultrasonographic investigation of the THG region and of cervical lymphatic nodes after performance of operation for THGC is recommended to conduct no less than once in 6 months.

In 1981-1998 years 552 children and juveniles were operated on for benign tumors of thyroid gland (TG). The enhancement of the revelation frequency of solitary and polynodous goiter and lowering of follicular adenoma and cystadenoma was noted. The tactics of children and juvenile patients with benign TG tumors was proposed, which included an early morphological verification of diagnosis, the puncture biopsy performance as well as intraoperative express-histological investigation. While solitary node in TG existence and preoperatively established its benign essence, extrafascial hemithyroidectomy, using original method, is the operative of choice.

Classification of operations on thyroid gland depending on the tissue volume preserved and basing on the analysis of surgical treatment of more than 2000 patients was presented. Substantiation and characteristics of its headings permits to take into account the intervention volume, what is peculiarly important during the automatized processing of large masses of information.
