221 patients were operated for cancer of the thyroid gland during the last 12 years. Adequate preoperative diagnosis including ultrasound examination, and fine needle aspiration biopsy made it possible to operate 88.7% of patients at earlier (I and II) stages of the disease. Long term results of radical surgical treatment have been studied in 197 (89.1%) patients followed up 5 to 16 years, 49.2% of patients being followed up for no less than 10 years. Majority of patients (95.9%) had differentiated forms of tumors, medullar cancer was detected in 4.1% of patients. Clinical and morphological analysis of differentiated thyroid cancer was carried out in 212 patients. Metastases to lymph nodes of the neck occur more frequently in younger patients, and extracapsular spread of the tumor was revealed in aged persons. Risk factors were male sex, old age, follicular cancer and growth of the tumor through the capsule of the gland. The minimal procedure in case of location of the differentiated tumor in a single lobe of thyroid is extrafascial hemithyreoidectomy with resection of the istmus. Prognosis in radically operated patients is relatively favourable, 5-year survival rate made up 97.5%. |
