[Management and prognostic factors for 119 patients with follicular thyroid carcinoma].

OBJECTIVE

To explore the optimal management and analyze the prognostic factors for follicular thyroid carcinoma.

METHODS

The clinicopathological data of 119 patients with well-differentiated follicular thyroid carcinoma treated in our hospital from 1970 to 2008 were retrospectively reviewed. The overall survival (OS) rate was estimated by Kaplan-Meier method. Log rank and Cox regression analyses were used to identify the prognostic factors.

RESULTS

The 5- and 10-year OS rates were 81.1% and 66.7%, respectively. The 3- , 5- and 10-year cumulative distant metastasis rates were 27.4%, 29.6% and 35.9%, respectively. The age of ≥ 45 years old was one of the most important factors affecting survival rate (P < 0.05) and an independent factor for distant matastasis.

CONCLUSIONS

Follicular thyroid carcinoma has some special features such as diffuse growth and vascular tumors thrombosis and with a relatively poor prognosis. The key measure to improve local control and prognosis is radical resection. Some aggressive management such as total thyroidectomy combined with (13)1I therapy and regular follow-up should be performed to improve the survival rate and to control postoperative distant metastasis for patients ≥ 45 years old.
