Background:
The incidence of palpables thyroid nodules in general population is 5% and the prevalence of non -palpable nodules is higher (35-60%) in the endemic goiter area. In the last years the new guidelines and new classification related to thyroid nodule have changed the indication to treat it.
Material And Method:
We analyzed the patients treated from January 2013 to June 2016 for Thyr 3 and Thyr 4 thyroid nodule sec. Bethesda system. We have divided in I and II period related to the 2.2014 and 2015 ATA guidelines and we have evaluated the indication to treat, the type of surgical procedure, the incidence of thyroid carcinoma and the adverse events.
Results:
We selected from 909 cases, 252 cases surgically treated with preoperative diagnosis of Thyr 3(80 cases) and Thyr 4(172 cases); carcinoma was found in 21/80 (26.2%) and in 62/172 (26.05%). The period was divided from January 2013 to December 2014 and from January 2015 to june 2016 (first and second period). In II period we found carcinoma in 8/40 Thyr3 and in 26/88 Thyr 4. The incidence of lobectomy in II period was higher than I period (p < 0.0001) sec.guidelines indications. No difference in adverse events. The number of cancer is lower in patients treated with lobectomy than those who underwent total thyroidectomy (12,5%vs 21,8% in Thyr 3; 15,3% vs 32% in Thyr 4).
Conclusions:
The indications to treat related to Thyr 3 and Thyr4 are changed in the two periods. The number of cancer is lower in patients treated with lobectomy. The new guidelines have changed the surgical approach to thyroid nodule.
