RESUMO
PURPOSE: Follicular thyroid carcinoma (FTC) is a relatively rare form of thyroid carcinoma that often presents at a more advanced stage of disease with a higher incidence of distant metastases because of its propensity for vascular invasion. However, FTC and papillary thyroid carcinoma (PTC) have similar prognoses when they are matched for age and stage. Therefore, this study was conducted to evaluate the useful prognostic factors and determine the optimal management of FTC. METHODS: This study was conducted on 216 patients with FTC who underwent thyroidectomy at our institutions between April 1986 and August 2006. The patients included 174 women and 42 men with a mean age of 41 (4~87) years, and patients underwent follow-up evaluation for a mean period of 114 (6~253) months. The potential risk factors for treatment outcome were calculated using multivariate analysis, and the prognostic accuracy of UICC/AJCC pTNM staging, AMES, AGES, MACIS, and Degroot classification for predicting survival were compared. RESULTS: During the follow-up period, 13 (6.0%) patients developed locoregional recurrences and 8 patients (3.7%) showed distant metastases. In addition, cause specific mortality was seen in 8 patients (3.7%). The overall survival and cause-specific survival (CSS) rates at 10 years were 95.4% and 89.3%, respectively, and these cases were accurately predicted by the AMES and pTNM staging systems. The Cox proportional hazards revealed that gender (P=0.015), angioinvasion (P=0.013), invasion to adjacent structure (P=0.003), widely invasive carcinoma (P=0.028), and distant metastases at the time of presentation (P<0.001) were independent prognostic factors for survival. CONCLUSION: The extent of surgery in cases of FTC should be individualized based on the clinicopathologic findings; Conservative surgery should be adequate for cases of minimally invasive FTC without angioinvasion, however total or near-total thyroidectomy should be conducted in cases of widely invasive and minimally invasive FTC with angioinvasion.

PURPOSE: Hurthle cell carcinoma (HCC) of the thyroid gland is a rare disease that represents 3% of all thyroid carcinomas. HCC has been known as a more aggressive disease than the usual differentiated thyroid carcinoma. However, the biologic behavior and optimal treatment have come under considerable debate in recent years. This study was performed to evaluate the clinicopathologic features and treatment outcome of HCC. METHODS: From April 1986 to August 2006, 18 patients with HCC and 216 patients with pure follicular carcinoma (PFC) underwent thyroidectomy at our institutions with a mean follow-up of 114 (range: 6~253) months. The clinicopathologic characteristics and treatment outcome of each group were compared, and the prognostic factors for disease-free survival were analyzed. RESULTS: There were 14 women and 4 men with a mean age of 50 (range: 26~76) years. Compared with PFC patients, all of clinicopathologic features of HCC patients were different (gender, age, tumor size, multifocality, angioinvaion, invasion to adjacent structures, the subclassification and initial distant metastasis), but the high incidence of bilaterality was similar to the PFC patients (P<0.0001). The cause- specific survival (CSS) rates at 10 years were 83.4% in the HCC patients and 89.3% in the PFC patients (P=0.702). Older age (greater than 45) (P=0.0125) and initial distant metastasis (P<0.0001) in the HCC patients, and an older age (P<0.0001), male gender (P=0.0039), angioinvasion (P= 0.0122), invasion to adjacent structures (P<0.0001), a widely invasive type (P=0.004) and initial distant metastasis (P<0.0001) in the PCC patients were independent prognostic factors for survival. CONCLUSION: After accounting for important biologic behaviors, patients with HCC had similar clinicopathologic characteristics and prognosis compared with that of the PFC patients. Therefore, HCC should be managed using the same treatment strategy as PFC.

Four cases of complete traumatic rupture of female urethra were reviewed. Herein the incidence, etiology and treatment modalities of complete rupture of female urethra are discussed to propose guidelines for the proper management of these unusual injuries. I recommend the following: Through the retropubic approach in children, a primary realignment with either surgery or an interlocking Foley catheterization should be performed as in the delayed retropubic urethroplasty when primary realignment was not accomplished. Transvaginal repair is considered choice approach for the urethro-vaginal laceration due to other than pelvic fracture in adults.
