SUMMARY OBJECTIVES: To analyze the experience in the surgical treatment of the thyroid carcinoma. METHODS: We evaluated 85 patients with carcinoma of thyroids treated in the Service of General Surgery Nº 1 of the University Hospital Miguel Perez Carreño, between 1970 and 2003. They were analyzed: the clinic, diagnosis, treatment, complications and follow up. The information was processed with the BMDP statistical package. The results are expressed in: frequency allocation, descriptive statistics. Comparisons of groups were by the Chi-square test, and Student t- test was used to value differences between averages. The survival curves were compared by the Mantel-Cox test. RESULTS: The histological diagnoses were papillary 64.70 %, follicular 17.64 %, medullar 10.58 %, undifferentiated 7.05 %. In 76 patients a palpable neck mass was the only clinical presentation of disease. The mean age was 48 years. Patients with papillary carcinoma were younger than those with follicular (P= 0.03). The female predominance being even more pronounced among patients less than 50 years old (3.6/1) compared with (2.3/1) among patients above 50. Thyroid Gammagrama revealed 74 % of none captivate nodes. Ultrasound test demonstrated a solitary node in 96 % of the cases. A total thyroidectomy was performed in 82 % of the patients, hemithyroidectomy or subtotal thyroidectomy in 12 %, the rest received palliative treatment. The recurrence rate was 6 %. CONCLUSIONS: It is necessary randomized and prospective studies to improve the knowledge on the evolution and treatment of the carcinoma of the thyroid.
