Background/Aims: Follicular thyroid carcinoma (FTC) and Hurthle cell carcinoma(HCC) of the thyroid are relatively uncommon thyroid malignancies in iodine-sufficient areas. In this study we evaluated the clinical behavior, prognosticfactors and treatment outcomes of FTC and HCC in Korea. Methods: This multicenter study included 483 patients with FTC and 80 patientswith HCC who underwent an initial surgery between 1995 and 2006 in one of thefour tertiary referral hospitals in Korea. We evaluated clinicopathological factorsassociated with distant metastases and recurrence during a median of 6 years offollow-up. Results: HCC patients were significantly older (49 years vs. 43 years; p < 0.001) andhad more lymphovascular invasions (22% vs. 14%; p = 0.03) compared with FTCpatients. Distant metastases were confirmed in 40 patients (8%) in the FTC groupand in two patients (3%) in the HCC group (p = 0.07). Distant metastases weresignificantly associated with older age, widely invasive cancer and extrathyroidalinvasion. Only 14 patients (3%) had recurrent disease and there was no significantdifference between FTC and HCC groups (p = 0.38). Recurrence was associatedwith larger tumor size and cervical lymph node metastasis. Conclusions: HCC patients were older and had more lymphovascular invasionsthan FTC patients. However, FTC and HCC patients had similar initial clinicopathologicalfeatures. Older age, wide invasiveness and extrathyroidal invasionwere independent risk factors for predicting distant metastases in FTC and HCCpatients.

Introduction: Diabetes mellitus, as a major health problem for the elderly has been shown to alter the properties of the bone and impair bone healing around a titanium implant in both humans and animals. The aim of this study was to examine the effect of adipose-derived stem cells on the healing process around a titanium implant in streptozotocin-induced diabetic rats. Materials and Methods: Thirteen rats were divided into two groups: adipose-derived stem cells injected group and a control group. A titanium screw implant (diameter: 2.0 mm, length: 3.5 mm) was placed into both tibia of 13 rats: 13 right tibia as the control group and 13 left tibia as the experimental group. The rats were sacrificed at different intervals (1, 2, and 4 weeks) after implantation for histopathology observations and immunohistochemistric analysis. Results: The histopathological findings revealed earlier new formed bone in the experimental group than the control group. In particular, at 1 week after implantation, the experimental group showed more newly formed bone and collagen around the implant than the control group. In immunohistochemistric analysis, osteoprotegerin (OPG) expression in the experimental group increased early compared to that of the control group until 2 weeks after implantation. However, after 2 weeks, OPG expression in the experimental group was similar to OPG expression in the control group. The receptor activator of nuclear factor κB ligand (RANKL) expression in the experimental group increased early compared to that of the control group, and then decreased at 2 weeks. After 2 weeks, the level of RANKL expression was similar in both groups. Conclusion: These results suggest that adipose-derived stem cells in implantation can promote bone healing around titanium, particularly in diabetes mellitus induced animals.
