Long-term Results of Papillary Thyroid Cancer Treatment and Comparative Analisis of Various Treatment Strategies

There are discriminating approaches towards differentiated thyroid carcinomas due to their different prognoses according to the European, American and Japanese thyroid recommendations. Materials and Methods. We have analyzed data on 331 patients with papillary thyroid cancer, operated on during the period of 1966-2000 years. Mean observation period was 18.8 years, the maximum period of observation was 57 years.Results. Survival rate analysis after surgical treatment showed favourable prognosis for thyroid cancer patients, adjusted for that there was no ultrasonography and FNAB during those years, and patients had generally more progressive tumours. One of the most important factors for the prognosis of a patient is the size of a tumour at the moment of operation and presence of distant metastases. Long-term results of surgical treatment are practically independent of its extent (thyroidectomy or thyroid resection, prophylactic lymphodissection). Mortality and recurrence rates in patients who were not submitted to radioactive iodine treatment do not differ considerably from literature data.
