Introduction and objectives: Radioiodine is the principal treatment for differentiated thyroid carcinomas. The aim of this study is to present our experience in the management of these tumours.
Material and method: We present a retrospective study of 55 patients operated for differentiated thyroid carcinoma in our hospital between 2007 and 2011.
Results: The mean age at time of diagnosis was 49 years, and females predominated (78% of cases). Seventy eight percent of the patients were in the initial stages (stages i and ii). The definitive histopathological diagnosis was papillary carcinoma in 84% and follicular carcinoma in the remaining 16%. All of the patients, with the exception of 2 (4%), underwent total thyroidectomy, with lymphadenectomy in 58% of cases. Nine percent of the patients had permanent hypoparathyroidism and although 18% suffered transitory unilateral paralysis, 40% of these female patients had completely recovered after 6 months. Eighty-nine percent of the patients were given radioiodine postoperatively. There was a recurrence rate of 40% most of which was at cervical level (29% of the patients). Survival at 5 years was 87%, 95% of the papillary subtype, falling to 56% of the follicular subtype (P=.001).
Discussion/conclusions: The prognosis for differentiated thyroid carcinomas is excellent after appropriate surgical treatment, thorough preoperative assessment,and strict postoperative follow-up due to the significant recurrence rates.
