[Differentiated thyroid carcinoma. Diagnosis and therapeutic aspects]

The significant increase in incidence of thyroid cancer in the last decade, augmented the interest in reevaluation of treatment and diagnosis methods. Those aspects let us into making this retrospective study regarding the differentiated thyroid carcinoma. The clinical material consist in 70 C.T. patients, of which 54 (77.14%) C.T.D. patients, ages between 17-80 year old, sex ratio W/M 3.5/1.9. Preoperatively malignancy diagnosis was made by FNAC in 38.88%, intraoperatively by extemporaneous pathological exam 42.59%, postoperatively by paraffin exam 18.51%. Papillary CTD 30 (55.55%), follicular 20 (41.25%), Hürthle cells carcinoma 4 (7.2%). From the therapeutical point of view, the elective procedure of thyroidectomy was dictated by the histological type, staging and specific prognostic factors. There was 41 (75.9%) patients with total thyroidectomy (T.T), with a specific morbidity of 7 (12.96%) and 5-years survival rate of 88.88%. Preoperatively diagnosis of C.T was suspected through clinic, ultrasonography and scintigraphy arguments and confirmed by FNAC. The non conclusive cases were diagnosed intraoperatively by extemporaneous exam or postoperatively by paraffin exam. In most cases total thyroidectomy remains the essential surgical procedure. Also clinical, imaging and biological postoperative monitoring as well as suppress and substitution hormonotherapy are mandatory.
