Surgery is still today the first choice treatment in the thyroid neoplasm. The authors examined 37 patients with thyroid cancer out of 389 thyroidal operation performed in the period 1982-85 at the Institute of Surgical Pathology II and Surgical Clinic of University of Bari. The pro-operation screening was scintigraphy, US study and needle biopsy. In 23 case, with positive cytology examination and/or clinical malignancy the performed operation was total extracapsular thyroidectomy. Other nine patients underwent lobectomy and in 2 cases the operation chosen was sub-total strumectomy completed by thyroidectomy after histologically proved malignancy. The laterocervical lymphadenectomy was done only in the case of nodes involvement. Operative mortality was 0 and post-operative stay was about 6 days. The extracapsular total thyroidectomy is the first choice operation for cancer. Nevertheless recently some Authors proposed less destructive operation in the small differentiated type cancers with good results.
