Abstract
BACKGROUND: A large proportion of follicular thyroid carcinoma (FTC) patients in developing countries present with overt skeletal metastases (SM). These patients often require surgical interventions for prevention of morbidity, palliation of symptoms, and facilitation of radioiodine therapy (RAIT). Scarce literature is available about the long-term outcome of such patients. The aim of this study was to evaluate the long-term outcome of FTC patients undergoing surgical intervention for SM. METHODS: We retrospectively reviewed the data of FTC patients with SM (January 1990-December 2011). Out of 91 patients with SM, 32 had surgical interventions for SM. All had total thyroidectomy performed. RESULTS: The mean age of the patients was 48.5 years (M:F = 1:2). Majority (93.7%) had synchronous metastases and 22% had multiple SM. The surgical interventions for SM included: laminectomy (50%), resection of skull metastases (18.8%), resection of manubrium sterni (18.8%), partial clavicle excision (9.4%), and hemimandibulectomy (3.1%). The main intents were palliation (50%) and facilitation of RAIT (37.5%). 84% patients received RAIT. Median follow-up was 52 months (mean = 50 ± 37). Five- (56 vs 63%) and 10-year (28 vs 23%) overall survival (OS) did not differ significantly (p = 0.968) from those not having interventions for SM. On univariate analysis tumor invasion (p = 0.006) and synchronous presentation of SM (p = 0.043) were significant risk factors for OS, whereas on multivariate analysis tumor invasion (p = 0.006) was significant. CONCLUSIONS: Surgical interventions directed at SM in FTC patients with overt multiple SM might not result in improve OS. However, considering reasonable long-term survival, interventions should be considered for desired palliation and preservation of body function.
