Abstract
Objective: The aim of this study was to investigate whether Central lymph node (CLN) size as measured by an ultrasound can significantly predict CLN metastasis of papillary thyroid carcinoma (PTC). Materials and methods: This retrospective chart review of patients diagnosed with PTC who underwent ultrasound and central neck dissection (CND). We excluded patients who received previous thyroid surgery or radiation. We analyzed the correlation between CLN size and characteristics by ultrasound and histopathologic findings among positive CLN patients. Results: Of the 48 patients who underwent preoperative ultrasound and CND, 34 patients had positive CLN identified by ultrasound. The positive predictive value, negative predictive value, sensitivity, specificity, and accuracy of ultrasound in this diagnostic setting was 88.0%, 21.0%, 73.2%, 42.9%, and 68.7%, respectively. The risk of CLN metastasis of PTC was 67.7% and 85.7% for lymph node size 3.1 to 4 mm and 4.1 to 5 mm, respectively. The risk increased to 100% when the lymph node size was >5 mm. Positive preoperative ultrasound of lateral neck lymph node was found to be a significant risk factor for CLN metastasis (P = .003). Conclusion: Ultrasound was found to be an effective preoperative evaluation in patients with PTC to determine the likelihood of CLN metastasis and whether CND is indicated, especially in the ultrasound-positive central lymph node. A high risk of metastasis was found in CLN size >3 mm by ultrasound, and the risk dramatically increased in CLN size >5 mm. We also found positive lateral neck node from preoperative ultrasound to be a significant risk factor for CLN metastasis.

Park J, Kang IK, Bae JS, Kim JS, Kim K. Clinical Significance of the Lymph Node Ratio of the Second Operation to Predict Re-Recurrence in Thyroid Carcinoma. Cancers (Basel) 2023; 15:cancers15030624. [PMID: 36765580 PMCID: PMC9913116 DOI: 10.3390/cancers15030624] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 01/11/2023] [Accepted: 01/17/2023] [Indexed: 01/20/2023] Open
Abstract
The purpose of this study was to establish the risk factors for re-recurrences and disease-specific mortality (DSM) in recurrent thyroid cancer. Patients with recurrent thyroid cancer who underwent initial thyroid surgery from January 2000 to December 2019 at Seoul St. Mary's Hospital (Seoul, Korea) were assessed. Clinicopathological characteristics and long-term oncologic outcomes were compared between patients with one recurrence (n = 202) and patients with re-recurrences (n = 44). Logistic regression and cox-regression analyses were conducted to determine the risk factors for re-recurrences and DSM, respectively. Receiver-operating characteristic curve analysis was performed to determine the cutoff value for lymph node ratio (LNR) as a predictor of re-recurrences. DSM was significantly higher in the re-recurrence group compared with the single-recurrence group (6.8% vs. 0.5%, p = 0.019). Surgical treatment at the first recurrence significantly lowered the risk of re-recurrences. Age (≥55), male sex, and LNR (≥0.15) were independent significant risk factors for re-recurrences in patients who underwent surgery at the first recurrence. Surgical resection is the optimal treatment for initial thyroid cancer recurrence. LNR at re-operation is more effective in predicting re-recurrence than the absolute number of metastatic LNs.

Abstract
PURPOSE In this study, we aimed to investigate the age-related risk of second breast cancer (SBC) and second gynecological malignant neoplasms (SGMNs) in female differentiated thyroid cancer (DTC) survivors by utilizing the Surveillance, Epidemiology, and End Results (SEER) database. METHODS A total number of 55,622 female DTC patients were identified between 1975 and 2016, including 2168 patients who developed SBC and SGMNs. The Fine and Gray model was used to calculate the cumulative incidence and sub-distribution hazards ratios (SHR). Poisson regression analysis was employed to calculate the relative risk (RR) and standardized incidence ratio (SIR). Kaplan-Meier survival and log-rank test analyses were also performed. RESULTS The overall 40-year cumulative incidence of SBC and SGMNs was 18.9%. Their incidence in the adolescent and young adults (AYA) group increased slowly in the first 30 years, but then was rapidly elevated in the last decade. It increased gradually in the middle-aged adults group and in the first 25 years in the older adults group, but it scarcely increased thereafter. Both the middle-aged adults (adjusted SHR, 2.09; RR, 1.76) and the older adults (adjusted SHR, 1.32; RR, 1.58) groups had higher risks of developing combined SBC and SGMNs than the AYA group. The risks increased mainly in the early latency period. The three groups also had higher SIRs than the US general population. Besides, the best survival after SBC and SGMNs was observed in the AYA group. CONCLUSIONS Age was an independent risk factor for SBC and SGMNs incidences among female DTC survivors.

Abstract
PURPOSE To compare the epidemiological, clinical, and pathological features of follicular (FVPTC) and classical (CVPTC) variants of papillary thyroid cancer and to correlate their outcomes according to different features. METHODS Retrospective analysis of FVPTC and CVPTC patients selected at the moment of surgical treatment from 1999 to 2004, with a median follow-up of 15 years. RESULTS Several significant differences were found between FVPTC and CVPTC such as the mean age at diagnosis, the presence of tumor capsule, the presence of thyroid capsule invasion, the presence of perithyroid soft tissue invasion, the lymph node metastases, the multifocality and bilaterality. At the end of follow-up only 9% (77/879) patients were not cured. However, a statistically significant lower percentage of persistent disease was found in the FVPTC than in the CVPTC group (3% vs. 14.5%, respectively, p < 0.0001). In multivariate analysis, the absence of the tumor capsule (OR = 6.75) or its invasion (OR = 7.89), the tumor size ≥4 cm (OR = 4.29), the variant CVPTC (OR = 3.35), and the presence of lymph node metastases (OR = 3.16) were all independent risk factors for the persistence of the disease. CONCLUSIONS Despite an overall excellent prognosis of both variants, a higher percentage of CVPTC than FVPTC patients had a persistent disease. The absence of tumor capsule or its invasion, the tumor size ≥4 cm and the presence of lymph node metastases are other prognostic factors for the persistence of the disease. In contrast, the presence of an intact tumor capsule is the only good prognostic factor for their outcome.

Abstract
BACKGROUND Differentiated thyroid cancers often require radioiodine treatment followed by posttreatment scan. We aimed in this study to assess the utility of the posttreatment radioiodine scan in this population. METHODS An analysis of patients who received radioiodine treatment at Rambam Campus, during 2006-2013. Scans showing remnant normal thyroid tissue were considered as normal. Positive uptake was defined as uptake in the lateral neck or distant sites. RESULTS A total of 455 patients were analyzed, 68% had T1-T2 and 28% had positive lymph nodes. Positive uptake in the lateral neck was recorded in 52 (11.4%) and in distant sites in 41 (9%) patients. Tracheal invasion, esophageal invasion, nerve invasion, and N1b classification were associated with a positive scan (P < .05). A positive radioactive iodine scan was not related to poor prognosis. CONCLUSIONS Posttreatment scans are positive in only 20% of patients. Locally invasive tumor and positive nodes are associated with positive scans.

Abstract
The incidence of thyroid cancer in females is significantly higher than that in males; however, females are more likely to have more favorable outcomes. We aimed to determine the characteristics of differentiated thyroid carcinoma (DTC) subtypes in males and females, and to compare their clinical behavior and survival. A total of 68,337 cases were recruited from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) Program. The disease-specific survival (DSS) of follicular variant papillary thyroid carcinoma (FVPTC) and follicular thyroid carcinoma (FTC) were similar to that of classical variant papillary thyroid carcinoma (CPTC) in male patients (FVPTC vs. CPTC, adjusted hazard ratio (aHR) = 0.947, P = 0.776; FTC vs. CPTC, aHR = 1.512, P = 0.104). In premenopausal female (< 55 years old), FVPTC had better DSS than CPTC (aHR = 0.321, P = 0.038) while FTC had worse DSS than CPTC (aHR = 3.272, P = 0.013); in postmenopausal female, FTC had poorer prognosis than CPTC (aHR = 2.145, P = 0.002), no statistical difference was found between CPTC and FVPTC (aHR = 0.724, P = 0.087). For patients younger than 55 years, women had significantly better DSS compared with men with CPTC (aHR = 0.376, P < 0.001) and FVPTC (aHR = 0.102, P < 0.001). However, no difference was observed in patients older than 55 years. Interestingly, outcomes of FTC were not affected by gender in patients of all ages. These results suggested that different clinical behaviors and outcomes of DTC subtypes should be considered in patients with different genders.

Abstract
BACKGROUND The incidence of thyroid cancer in black Americans is significantly lower than that in white Americans, and the impact of race on the prognosis of thyroid cancer remains controversial. The purpose of this study was to determine the risk factors for survival in black and white patients and to compare the survival of differentiated thyroid carcinoma subtypes between these two races. We further investigated the association of lymph node and distant metastases with races. METHODS This is a retrospective analysis using data from the National Cancer Institute's Surveillance, Epidemiology, and End Results Program. A total of 70,346 cases were included in our study. Patients' demographics and cancer- and treatment-related characteristics were compared between the black and white Americans using chi-square and Fisher's exact tests. For multivariate analysis, Cox proportional hazards regression were used to assess the association between potential risk factors and the survival in black and white patients. RESULT Black Americans had a worse overall survival than white Americans (HR = 1.127, P = 0.002). While disease-specific survival (DSS) was comparable, the risk factors for DSS were different between white and black Americans. Black Americans had less lymph node metastasis of classical variant papillary thyroid carcinoma (CPTC, OR = 0.476, P < 0.001) and follicular variant papillary thyroid carcinoma (FVPTC, OR = 0.522, P < 0.001), but not follicular thyroid carcinoma (FTC). However, black Americans with FVPTC, but not CPTC or FTC, had a higher potential of distant metastasis (OR = 1.715, P = 0.026). Furthermore, only white patients with tumor > 2 cm and lymph node metastasis benefited from radioactive iodine. CONCLUSIONS The risk factors for DSS were significantly different in white and black patients. The impact of race should be considered in treatment strategy for thyroid cancer.

Abstract
Follicular variant papillary thyroid cancer (FVPTC) is the second most common subtype after conventional PTC. We compared ultrasonographic (US) features of FVPTC to those of conventional PTC according to tumor size. We reviewed US findings, pathologic reports, and medical charts of 249 PTC patients with surgically proven disease (83 FVPTCs, 166 conventional PTCs) at our institution from January 2007 to December 2012. FVPTCs were divided into PTC-like and follicular neoplasm (FN)-like based on sonographic characteristics. PTC-like features were defined as having at least one malignant feature (taller-than-wide shape, infiltrative margin, marked hypoechogenicity, and micro-calcifications), whereas FN-like cancers showed oval solid features without malignant features. FVPTCs showed a higher rate of FN-like features than conventional PTCs. Of 166 conventional PTCs, 13 (7.8%) had FN-like features and 153 (92.2%) had PTC-like features, whereas of the 83 FVPTCs, 31 (37.3%) had FN-like features and 52 (62.7%) had PTC-like features. Macro-FVPTCs showed a higher rate of FN-like features than micro-FVPTCs (P < 0.001). Of 21 macro-FVPTCs, 18 (85.7%) had FN-like features and 3 (14.3%) had PTC-like features, whereas of the 62 micro-FVPTCs, 13 (21%) had FN-like features and 49 (79%) had PTC-like features. There were no differences in multifocality, extrathyroidal invasion, and lymph node metastasis between PTC-like FVPTCs and FN-like FVPTCs. FVPTCs showed fewer sonographic malignant features than conventional PTCs. In particular, FVPTCs larger than 1 cm had a more frequent benign sonographic appearance. Therefore, if fine-needle aspiration result is suspicious for PTC in a nodule larger than 1 cm with no suspicious US features, the possibility of FVPTC might be considered.

Abstract
CONTEXT Thyroid carcinoma is the most common malignant tumor of endocrine organs, yet it only accounts for approximately 1% of all cancers in the United States with more than 35,000 new cases diagnosed each year and more than 450,000 people living with this disease. While most tumors can be diagnosed without much difficulty, a few tumor types, especially tumors with follicular pattern, sometimes pose a diagnostic challenge. OBJECTIVE To discuss morphologic, immunohistochemical, and molecular features of thyroid tumors. We also explore the clinicopathologic features of papillary microcarcinoma and medullary microcarcinoma and how the latter is related and differentiated from C-cell hyperplasia. Finally with the ever-growing list of organ systems involved in immunoglobulin (Ig) G4-related diseases, we discuss the still not completely explored IgG-4-related thyroid disease. DATA SOURCES Data were obtained from review of the pertinent peer-reviewed literature and institutional experience. CONCLUSIONS Histomorphologic evaluation still remains the gold standard for diagnosis in most cases of thyroid diseases. The application of ancillary studies such as immunohistochemistry and molecular diagnosis, including next-generation sequencing, is becoming more common.

Abstract
Differentiated thyroid carcinoma (DTC) comprises over 90% of thyroid tumors and includes papillary and follicular carcinomas. Patients with DTC have an excellent prognosis, with a 10-year survival rate of over 90%. However, the risk of recurrent tumor ranges between 5% and 30% within 10 years of the initial diagnosis. Cervical lymph node disease accounts for the majority of recurrences and in most cases is detected during follow-up by ultrasound or elevated levels of serum thyroglobulin. Recurrent disease is accompanied by increased morbidity. The mainstay of treatment of nodal recurrence is surgical management. We provide an overview of the literature addressing surgical management of recurrent or persistent lymph node disease in patients with DTC.

Abstract
PURPOSE To compare the histopathological features and the outcomes of the follicular variant and classical variant of papillary thyroid carcinoma. MATERIAL AND THE METHODS Demographic data, histopathological features (tumor size, thyroid capsule invasion, extrathyroidal extension, vascular invasion and multicentricity), lymph node metastasis, local recurrence, distant metastasis and mortality during the follow-up of 258 C-PTC and 153 FVPTC patients who underwent total thyroidectomy were compared. The dynamic risk assessment system was used to refine postoperative risk estimates based on the assessment of response to initial treatment. RESULTS The demographic data showed no significant difference between the two groups. The mean tumor size showed no significant difference between the two groups. The rate of thyroid capsule invasion, extrathyroidal extension, and lymph node metastasis was significantly higher in C-PTC than in FVPTC group, whereas multicentricity and bilobar involvement were significantly higher in FVPTC group than in C-PTC group. Central lymph node metastasis was significantly more frequent in patients with C-PTC than in those with FVPTC (p < 0.0001). Local recurrence was found in 22 (5.3 %) patients overall and was significantly more common in C-PTC group than in FVPTC group. In patients ≥45 years, the local recurrence rate was significantly higher in patients with CPTC than in those with FVPTC. The local recurrence rate in patients <45 years was not significantly different between the two groups of patients. The multicentricity rate was significantly higher in the FVPTC group for both age groups. Dynamic risk assessment showed that the rate of intermediate- and high-risk groups showed no significant difference between C-PTC and FVPTC patients but the rate of low risk patients was higher in FVPTC group than in C-PTC group (p = 0.04). The recurrence rate in low-risk group was found higher in C-PTC compared to FVPTC patients (4.7 vs. 0.7 %, p = 0.04, respectively). The recurrence rate showed no significant difference in both intermediate- and high-risk groups in C-PTC and FVPTC patients. During the follow-up, the rate of distant metastasis and disease-specific mortality was not significantly different between the two groups (p = 0.25). CONCLUSION FVPTC is a common subtype of PTC and has a higher rate of multicentricity with bilobar involvement. Although aggressive histopathologic features, such as thyroid capsule invasion, extrathyroidal extension, and lymph node metastasis, are significantly more frequent in CPTC than in FVPTC, the long-term outcome is similar in both subtypes after appropriate initial surgery and postoperative RAI ablation treatment.

Abstract
Thyroid cancer is the most common endocrine neoplasm; however, it only accounts for less than 1% of all human malignances. Thyroid cancers are divided into well differentiated and non-well differentiated cancers, according to their histology and behavior. The surgical management options of well-differentiated thyroid cancer include total or near-total thyroidectomy, subtotal thyroidectomy and lobectomy plus isthmusectomy. The extent of surgery for thyroid cancer continues to be an area of controversy. Complications associated with thyroid surgery are directly proportional to the extent of thyroidectomy and inversely proportional to the experience of the operating surgeon. They occur less frequently with good surgical technique and better understanding of surgical anatomy, and include wound healing and infections (seroma, hematoma and wound infection), nerve injury, hypoparathyroidism, hypothyroidism, postoperative hemorrhage and respiratory obstruction.

Abstract
BACKGROUND Follicular variant of papillary thyroid carcinoma (FV-PTC) has been increasingly diagnosed in recent years. However, little is known about its clinical behavior. The purpose of this study was to determine the disease characteristics of FV-PTC, and to compare it with classical papillary thyroid carcinoma (C-PTC) and follicular thyroid carcinoma (FTC). METHODS All cases of C-PTC, FV-PTC, and FTC larger than 1 cm in the Surveillance, Epidemiology and End Results (SEER) Cancer Database from 1988 to 2007 were identified. Tumor behavior and patient survival were compared among these three groups. Different risk factors for disease-specific mortality in each group were evaluated by multivariate analysis. RESULTS More than 36,000 surgical cases were identified, including 21,796 C-PTCs, 10,740 FV-PTCs, and 3958 FTCs. Extrathyroidal extension and lymph-node metastases were more common in FV-PTC than in FTC, but significantly less common than in C-PTC (p<0.0001). Distant metastasis rates were present in 2% of patients with FV-PTC, in 1% with C-PTC, and in 4% with FTC (p<0.0001). The 10-year disease-specific survival for patients with FV-PTC was 98%, similar to C-PTC (97%) but better than FTC (94%, p<0.0001). Being over the age of 45 years remained a strong risk factor for disease-specific mortality in both FV-PTC and C-PTC, while the presence of extrathyroidal extension and distant metastases were stronger predictors of disease-specific mortality in FV-PTC than in C-PTC. CONCLUSIONS FV-PTC is a common variant of PTC. Its clinical behavior is unique and represents an intermediate entity with clinical features that are between C-PTC and FTC. Interestingly, despite the variations in clinical behavior, the long-term outcome of these patients remains excellent and similar to C-PTC.

Abstract
Many human tumors show significant changes in their signal transduction pathways and, thus, the way the cells interact with their environment. Often caused by chromosomal rearrangements, including gene amplifications, translocations or deletions, the altered levels of gene expression may provide a tumor-specific signature that can be exploited for diagnostic or therapeutic purposes. We investigated the utility of multiplexed fluorescence in situ hybridization (FISH) using non-isotopically labeled cDNA probes detected by Spectral Imaging as a sensitive and rapid procedure to measure tumor-specific gene expression signatures. We used a commercially available system to acquire and analyze multicolor FISH images. Initial investigations used panels of fluorescent calibration standards to evaluate the system. These experiments were followed by hybridization of five-to-six differently labeled cDNA probes, which target the transcripts of tyrosine kinase genes known to be differently expressed in normal cells and tumors of the breast or thyroid gland. The relatively simple, yet efficient, molecular cytogenetic method presented here may find many applications in characterization of solid tumors or disseminated tumor cells. Addressing tumor heterogeneity by means of multi-parameter single cell analyses is expected to enable a wide range of investigations in the areas of tumor stem cells, tumor clonality and disease progression.

Abstract
Papillary thyroid carcinoma is the most common form of differentiated thyroid carcinoma. It is generally confined to the neck with or without spread to regional lymph nodes. Metastatic thyroid carcinomas are uncommon and mainly include lung and bone. Metastases involving oral and maxillofacial region are extremely rare. We described a case of malar metastasis revealing a follicular variant of papillary thyroid carcinoma, presenting with pain and swelling of the left cheek in a 67-years-old female patient with an unspecified histological left lobo-isthmectomy medical history. To our knowledge, this is the first recorded instance of a malar metastasis from a follicular variant of papillary thyroid carcinoma.

Abstract
Altered signal transduction can be considered a hallmark of many solid tumors. In thyroid cancers the receptor tyrosine kinase (rtk) genes NTRK1 (Online Mendelian Inheritance in Man = OMIM *191315, also known as 'TRKA'), RET ('Rearranged during Transfection protooncogene', OMIM *164761) and MET (OMIM *164860) have been reported as activated, rearranged or overexpressed. In many cases, a combination of cytogenetic and molecular techniques allows elucidation of cellular changes that initiate tumor development and progression. While the mechanisms leading to overexpression of the rtk MET gene remain largely unknown, a variety of chromosomal rearrangements of the RET or NTKR1 gene could be demonstrated in thyroid cancer. Abnormal expressions in these tumors seem to follow a similar pattern: the rearrangement translocates the 3'- end of the rtk gene including the entire catalytic domain to an expressed gene leading to a chimeric RNA and protein with kinase activity. Our research was prompted by an increasing number of reports describing translocations involving ret and previously unknown translocation partners.We developed a high resolution technique based on fluorescence in situ hybridization (FISH) to allow rapid screening for cytogenetic rearrangements which complements conventional chromosome banding analysis. Our technique applies simultaneous hybridization of numerous probes labeled with different reporter molecules which are distributed along the target chromosome allowing the detection of cytogenetic changes at near megabasepair (Mbp) resolution. Here, we report our results using a probe set specific for human chromosome 10, which is altered in a significant portion of human thyroid cancers (TC's). While rendering accurate information about the cytogenetic location of rearranged elements, our multi-locus, multi-color analysis was developed primarily to overcome limitations of whole chromosome painting (WCP) and chromosome banding techniques for fine mapping of breakpoints in papillary thyroid cancer (PTC).

Abstract
OBJECTIVE The objective of the study was to determine the outcome of surgical resection of metastatic papillary thyroid cancer (PTC) in cervical lymph nodes after failure of initial surgery and I(131) therapy. DESIGN This was a retrospective clinical study. SETTING The study was conducted at a university-based tertiary cancer hospital. PATIENTS A cohort of 95 consecutive patients with recurrent/persistent PTC in the neck underwent initial reoperation during 1999-2005. All had previous thyroidectomy (+/-nodal dissection) and I(131) therapy. Twenty-five patients with antithyroglobulin (Tg) antibodies were subsequently excluded. MAIN OUTCOME MEASURES Biochemical complete remission (BCR) was stringently defined as undetectable TSH-stimulated serum Tg. RESULTS A total of 107 lymphadenectomies were undertaken in these 70 patients through January 2010. BCR was initially achieved in 12 patients (17%). Of the 58 patients with detectable postoperative Tg, 28 had a second reoperation and BCR was achieved in five (18%), seven had a third reoperation, and none achieved BCR. No patient achieving BCR had a subsequent recurrence after a mean follow-up of 60 months (range 4-116 months). In addition, two more patients achieved BCR during long-term follow-up without further intervention. In total, 19 patients (27%) achieved BCR and 32 patients (46%) achieved a TSH-stimulated Tg less than 2.0 ng/ml. Patients who did not achieve BCR had significant reduction in Tg after the first (P < 0.001) and second (P = 0.008) operations. No patient developed detectable distant metastases or died from PTC. CONCLUSIONS Surgical resection of persistent PTC in cervical lymph nodes achieves BCR, when most stringently defined, in 27% of patients, sometimes requiring several surgeries. No biochemical or clinical recurrences occurred during follow-up. In patients who do not achieve BCR, Tg levels were significantly reduced. The long-term durability and impact of this intervention will require further investigation.

Abstract
Our understanding of the molecular pathophysiology of differentiated thyroid cancer (DTC) has developed considerably over the last 10 years. Aberrant signaling through B-Raf and Akt has been implicated in the tumorigenesis of DTC. Moreover, these highly vascular tumors have proven to be sensitive to the inhibition of vascular endothelial growth factor receptor (VEGFR-2). It is likely that the multikinase inhibitors, sorafenib, sunitinib, axitinib, and motesanib, whose targets include VEGFR-2, exert their effects primarily through inhibition of endothelial cells. However, as VEGFR-2 is expressed on DTC cells, these compounds may have direct antitumor action. This review will discuss the key signaling pathways involved in thyroid cancer and their implications for targeted therapy.

Abstract
Structural chromosome aberrations are known hallmarks of many solid tumors. In the papillary form of thyroid cancer (PTC), for example, activation of the receptor tyrosine kinase (RTK) genes, RET and neurotrophic tyrosine kinase receptor type I (NTRK1) by intra- and interchromosomal rearrangements has been suggested as a cause of the disease. However, many phenotypically similar tumors do not carry an activated RET or NTRK-1 gene or express abnormal ret or NTRK-1 transcripts. Thus, we hypothesize that other cellular RTK-type genes are aberrantly expressed in these tumors. Using fluorescence in situ hybridization-based methods, we are studying karyotype changes in a relatively rare subgroup of PTCs, i.e., tumors that arose in children following the 1986 nuclear accident in Chernobyl, Ukraine. Here, we report our technical developments and progress in deciphering complex chromosome aberrations in case S48TK, an aggressively growing PTC cell line, which shows an unusual high number of unbalanced translocations.

Abstract
Doxorubicin and camptothecin are two cytotoxic chemotherapeutic agents triggering apoptosis in various cancer cells, including thyroid carcinoma cells. Recent studies revealed a critical role of ceramide in chemotherapy and suggested that anti-cancer drugs may kill tumor cells through sphingomyelinase activation. However, in comparison to sphingomyelin hydrolysis, the relative involvement of de novo ceramide synthesis remained poorly explored and highly controversial. Here, we evidenced that both doxorubicin and camptothecin triggered ceramide accumulation in thyroid carcinoma cells. We demonstrated that ceramide increase occurred via the de novo pathway without neither acidic nor neutral sphingomyelinase contribution. Interestingly, de novo ceramide generation was responsible for the drug-induced malignant cell apoptosis through a caspase-3-dependent pathway and a decrease of thrombospondin amount. Furthermore, blocking ceramide metabolism by inhibiting glucosylceramide synthase strengthened the camptothecin and doxorubicin-dependent effects. Altogether, we evidenced that de novo ceramide synthesis mediates the anti-tumor properties of doxorubicin and camptothecin in thyroid carcinoma and suggested that glucosylation of ceramide may contribute to the drug-resistance phenotype in thyroid malignancies.

Abstract
Thyroid microcarcinoma are well-differentiated tumors less than 1 cm in diameter. A retrospective analysis was performed on patients operated of benign thyroid disease at the Center for endocrine surgery, Institute of endocrinology, Clical Center of Serbia in Belgrade, from January 1st to December 31st 2004, in order to establish the incidence of microcarcinoma. Indications for surgery were euthyroid multinodular goiter in 201 patients, thyroiditis in 31, thyroid adenoma in 178, Graves disease in 89 and Plummers disease in 79 patients. The results of this study, demonstrate that in 13.4% of the patients operated for goiter, 6.4% operated for thyroiditis, 5.6% for thyroid adenomas, 9.0% for Graves disease and 7.0% of the patients operated for Plumers disease, the presence of a microcarcinoma was noticed in the definitive histopathologic examination. The results obtained are in line with the current knowledge of high incidence of thyroid microcarcinoma.

Abstract
BACKGROUND The extent of surgery for papillary thyroid cancers (PTC) remains controversial. Consensus guidelines have recommended total thyroidectomy for PTC > or =1 cm; however, no study has supported this recommendation based on a survival advantage. The objective of this study was to examine whether the extent of surgery affects outcomes for PTC and to determine whether a size threshold could be identified above which total thyroidectomy is associated with improved outcomes. METHODS From the National Cancer Data Base (1985-1998), 52,173 patients underwent surgery for PTC. Survival was estimated by the Kaplan-Meier method and compared using log-rank tests. Cox Proportional Hazards modeling stratified by tumor size was used to assess the impact of surgical extent on outcomes and to identify a tumor size threshold above which total thyroidectomy is associated with an improvement in recurrence and long-term survival rates. RESULTS Of the 52,173 patients, 43,227 (82.9%) underwent total thyroidectomy, and 8946 (17.1%) underwent lobectomy. For PTC <1 cm extent of surgery did not impact recurrence or survival (P = 0.24, P = 0.83). For tumors > or =1 cm, lobectomy resulted in higher risk of recurrence and death (P = 0.04, P = 0.009). To minimize the influence of larger tumors, 1 to 2 cm lesions were examined separately: lobectomy again resulted in a higher risk of recurrence and death (P = 0.04, P = 0.04). CONCLUSIONS The results of this study demonstrate that total thyroidectomy results in lower recurrence rates and improved survival for PTC > or =1.0 cm compared with lobectomy. This is the first study to demonstrate that total thyroidectomy for PTC > or =1.0 cm improves outcomes.

Abstract
INTRODUCTION Recently, more aggressive variants of so-called well-differentiated thyroid carcinomas have been identified such as the tall cell variant, columnar cell variant, diffuse sclerosing variant, insular carcinoma, and Hürthle cell (oncocytic, oxyphilic) carcinomas. METHODS An evidence-based review was performed to identify the optimal treatment recommendations for these thyroid cancers of intermediate differentiation. CONCLUSIONS Although some variation exists within the group, aggressive surgical and medical management are recommended for these neoplasias. Any such recommendations should, however, be viewed in the light of the fact that the current literature mainly consists of case reports, case series, and limited reviews. The clinical presentation, pathophysiology, diagnosis, and surgical and medical management for these thyroid cancers with intermediate differentiation are discussed.

Abstract
Histone deacetylase (HDAC) inhibitors have been shown to reverse repression of some genes, including retinoic acid (RA) receptor beta2. In this work, we studied the effects of RA alone or combined with the HDAC inhibitor sodium butyrate (NaB) in a poorly differentiated thyroid carcinoma cell line (FTC-133) cultured in vitro or transplanted into nude mice. In vitro, the action of the xenobiotics on cell differentiation was evaluated by the measurement of alkaline phosphatase (ALP) activity. In vivo, FTC cells were injected in nude mice divided into four groups: controls, RA (1 mg/kg), NaB (50 mg/kg) in two daily injections or both RA plus NaB. Body weight, tumoral volume (TV), doubling time of the tumor, specific growth delay and inhibition of tumoral growth at day 35 were determined in each group. In vitro, RA increased the NaB-induced increase in ALP activity. In vivo, body weight and TV decreased with RA or NaB. Specific growth delay significantly increased with RA (72.5%; P < 0.001) and with NaB (31.3%; 0.02 <P <0.01). Inhibition of tumoral growth significantly fell to 50.3% (0.02 < P < 0.01) and 42.9% (0.05 < P < 0.02) with RA and NaB, respectively. The combination of RA with NaB induced no significant change in the different parameters observed in mice treated with RA alone. In conclusion, a synergistic effect between RA and NaB was observed in vitro on cell differentiation. The addition of NaB to RA induces no change in growth inhibition observed with RA alone in nude xenografts.

Abstract
Bone is the second most frequent site of metastasis resulting from thyroid cancer. Many studies have investigated clinical features and prognostic factors of distant metastases stemming from thyroid cancer in Western countries. The purpose of this study was to review clinical characteristics of Korean patients with bone metastasis originating from thyroid cancer. Between January 1985 and August 2004, 28 patients with thyroid cancer were diagnosed with bone metastases at the Yonsei Severance Hospital in Seoul, Korea. Their clinical characteristics were analyzed retrospectively. Incidence of bone metastasis from follicular thyroid cancer was 6.8% (9 of 132 patients), and 0.4% (13 of 3,154 patients) from papillary thyroid cancer, with an odds ratio of 17.67 (95% confidence interval; 7.41-42). Twelve patients had no symptoms of bone metastasis. Overall mean number of metastasis sites was 2.6 +/- 1.9, and 12 patients had a solitary bone metastasis. Survival rates between the synchronous and metachronous metastasis groups were not significantly different, and the number of metastasis sites did not affect survival. However, the survival of patients that underwent curative treatment was longer than those with palliation (P = 0.0317). In Korea, the overall incidence of bone metastasis resulting from thyroid cancer was less than our expectation. Many patients were asymptomatic, and had a tendency of undergoing less aggressive or palliative treatment, even though the long-term survival of distant metastasis resulting from thyroid cancer with active treatment is relatively good. Further studies of the prognostic factors and effectiveness of various treatments of these patients are needed to enhance survival.

Abstract
Follicular neoplasms of the thyroid are usually diagnosed following fine-needle aspiration (FNA) biopsy of a dominant thyroid nodule. An FNA diagnosis of a follicular neoplasm represents a heterogeneous group of lesions including benign follicular hyperplasia, follicular adenomas, follicular carcinomas, and the follicular variant of papillary carcinoma. Hürthle cell neoplasms are also often included in this group. Because the criteria for malignancy in both follicular and Hürthle cell neoplasms requires vascular or capsular invasion seen on permanent histology, the majority of these patients undergo surgical resection. Intraoperative frozen section analysis of follicular neoplasms rarely renders informative information. Approximately 20% of these lesions prove to be malignant and for lesions greater than 1.0 cm in size, the majority of surgeons and endocrinologists recommend a total thyroidectomy. Postoperative treatment generally includes therapeutic doses of 131I for follicular carcinomas.

Abstract
OBJECTIVE This study evaluates the incidence and risk factors of complications in patients submitted to thyroidectomy for differentiated thyroid carcinoma in a cancer hospital with residency training. STUDY DESIGN A retrospective chart and complications review of 316 consecutive patients who underwent thyroidectomy for differentiated thyroid carcinoma. RESULTS Of the 316 patients, the main postoperative complications were transient hypocalcemia in 87 (27.5%), permanent hypocalcemia in 16 (5.1%), transient vocal cord palsy in 4 (1.2%), and permanent vocal cord palsy in 2 (0.6%). Neck dissection and paratracheal lymph node dissection when associated with total thyroidectomy were significantly related to transitory and permanent hypocalcemia. CONCLUSION Thyroid surgery can be performed safely in a hospital with medical residency training program under direct supervision of an experienced surgeon with acceptable morbidity. Hypocalcemia is the most significant complication. Neck and paratracheal lymph node dissections were the most significant predictors of hypocalcemia in patients submitted to total thyroidectomy.

Abstract
Sentinel lymph node (SLN) was defined as the first lymph node that the tumor would drain to, within that tumors regional lymphatic basin. In 1998, Kelemen and coworkers have published the first results on SLN lymphonodectomy in thyroid carcinomas. Different methods have been used in a goal of lymphatic mapping (application of vital blue dye and/or radiocolloid). In a period from 2001 to 2003 we have performed SLN biopsy in 64 patients with thyroid tumors. There were 12 cases of thyroid carcinoma. SLN identification rate was 73.44%. We found no false positive or negative results on definitive histopathology. The impact of lymph node metastases in differentiated thyroid carcinoma is still controversial. The management of cervical lymph nodes varies from berry picking to modified radical neck dissection. There is a significant disproportion in percentage of pre and intraoperatively enlarged lymph nodes (27-45%) and histologically confirmed lymph node metastases (80-90%) in papillary thyroid carcinoma. In the current literature the average rate of SLN identification is 91% (66-100%) and when identified, the SLN accurately predicts the disease status of the neck in most patients (80-100%). The SLN biopsy for thyroid carcinoma is good and feasible technique for estimating the cervical lymph node status.

Abstract
UNLABELLED The Aim of the paper was to give a review of an early diagnosis, therapy, follow-up and survival rate of patients with thyroid malignancy (TM). The paper presented the algorithm of early diagnosis: clinical, scintigraphic and ultrasonographic examination together with fine needle biopsy, cytologic analysis of the smear and biopsy ex tempore of the clear and suspected thyroid node to malignancy. Therapy of all TM forms was mainly surgical: postsurgical treatment was dependent on the type of malignancy: radioiodine 131-I, radiologic treatment, chemotherapy and radioimmunotherapy, (the latest one being in the phase of a clinical research). Follow-up was in accordance with the protocol and it was necessary because it contributes to the survival rate. In the presentation of survival rate for differentiated and medullar carcinomas we gave our results and literature data, while for the other malignancies only data from literature were presented. CONCLUSION Only an early diagnosis of the nodular goiter together with an up-to-date treatment can cure TM patients in a high percentage and prevent development of a terminal stage of the disease which is extremely severe in all forms of this malignancy.

Abstract
The authors believe that total or near total thyroidectomy followed by 131I ablation and thyroid hormone suppression therapy are there commended extent of surgery and treatment of choice in differentiated thyroid cancer. This is based on retrospective data showing that total thyroidectomy plus 131I and thyroid stimulating hormone (TSH) suppression reduces disease recurrence and mortality, removes all intrathyroidal cancer, and facilitates the use of 131I scans and thyroglobulin measurements to monitor for recurrence. Recent decision analyses supporting this recommendation are summarized in this article. The recommendation comes with the caveat that total thyroidectomy must be performed safely with a low complication rate. With the institution of this appropriate treatment regimen, the prognosis for the majority of our patients with differentiated thyroid cancer is excellent.

Abstract
OBJECTIVES/HYPOTHESIS The outcome in differentiated thyroid cancer generally depends on the stage of the disease at the time of presentation; prognostic factors such as age, grade, size, extension, or distant metastasis; and risk groups (eg, low or high risk). The author has reviewed a large number of patients with differentiated thyroid cancer to analyze their hypothesis and to confirm that various risk groups have a major implication in relation to extent of the treatment and outcome. Differentiated thyroid cancers make up 90% of all thyroid tumors. The prognostic factors are well defined, such as age, size of the tumor, extrathyroidal extension, presence of distant metastasis, histological appearance, and grade of the tumor. The author has previously divided the risk groups into low-, intermediate-, and high-risk categories based on prognostic factors. The study describes the author's treatment approach related to the extent of thyroidectomy and adjuvant therapy based on various risk groups and the long-term survival. STUDY DESIGN Retrospective. METHODS In a retrospective review of 1038 patients with differentiated thyroid carcinoma, various prognostic factors were studied by univariate and multivariate analysis. The significant prognostic factors were studied in detail and, based on these prognostic factors, the patients were divided into low-, intermediate- and high-risk groups. The survival curves were plotted by Kaplan-Meier method. RESULTS The long-term survivals in low-, intermediate- and high-risk groups were 99%, 87%, and 57% respectively. Based on these risk groups, a decision tree was made regarding extent of thyroidectomy and adjuvant treatment. In the high-risk group and selected patients in the intermediate-risk group, aggressive surgery including removal of all gross disease and extrathyroidal extension with postoperative radioactive iodine ablation is recommended. In the low-risk group and selected patients in the intermediate-risk group, lobectomy appears to be satisfactory with excellent long-term outcome. The surgical treatment offers the best long-term results in low-risk patients, and the role of adjuvant treatment in this group is questionable. CONCLUSION The decisions in the management of well-differentiated thyroid cancer should be based on various prognostic factors and risk groups. The long-term survival in the low-risk group is excellent, and consideration should be given to conservative surgical resection depending on the extent of the disease. In the high-risk group and selected patients in the intermediate-risk group, total thyroidectomy with radioactive ablation is warranted. A consideration may be given to external-beam radiation therapy in selected high-risk patients. It is apparent, based on the author's clinical experience and critical retrospective analysis, that the author's hypothesis that risk groups are extremely important in the long-term outcome of patients with differentiated thyroid cancer is correct. Based on various risk groups, the author currently is able to guide the treatment policies for thyroid cancer.

Abstract
BACKGROUND The follicular variant of papillary thyroid carcinoma (FVPTC) is a common subtype of papillary thyroid carcinoma. Few studies have compared the clinical behavior and treatment outcome of patients with FVPTC with the outcome of patients with pure papillary carcinoma (PTC). A retrospective study was performed to identify the influence of FVPTC compared with PTC on therapeutic variables, prognostic variables, and survival. METHODS A clinicopathologic analysis of 243 patients with papillary carcinoma was performed. One hundred forty-three tumors were PTC, and 100 tumors were FVPTC. The following variables were evaluated: age at diagnosis, tumor size, stage of tumor, treatment, capsular invasion, and survival. RESULTS The median follow-up was 11.5 years. The median age was 43 years in the PTC group and 44 years in the FVPTC group. The median tumor size, disease stage, and type of initial surgery and iodine 131 ablation were similar. More patients had capsular invasion by the tumor and less metastases to cervical lymph nodes in the FVPTC group. The actuarial survival of patients age < 40 years was higher compared with the survival of patients age > 50 years in both groups. The 21-year overall actuarial survival was 82% in patients with PTC and 86% in patients with FVPTC (P value not significant). CONCLUSIONS The pathologic and clinical behaviors of PTC and FVPTC were comparable. Prognostic factors, treatment, and survival also were similar. Patients in both groups must be treated identically.

Abstract
OBJECTIVES When a diagnosis of thyroid cancer is returned following unilateral lobectomy, removal of the contralateral lobe is frequently necessary. Morbidity for completion thyroidectomy includes a reported 2% to 5% risk of recurrent laryngeal nerve (RLN) injury and an 8% to 15% incidence of hypoparathyroidism. In this study, to determine morbidity following completion thyroidectomy, we reviewed our results of reoperative surgery among patients with thyroid cancer. STUDY DESIGN Retrospective chart review. METHODS Between 1997 and 2000, 36 consecutive patients, 32 females and 4 males, with a mean age of 43.6 years (range, 19-59 y), underwent completion thyroidectomy. Preoperative fine-needle aspiration revealed follicular derived neoplasm in 32 patients (88.9%), indeterminate in 3 patients (8.3%), and Hürthle cell neoplasm in 1 patient (2.8%). The interval between the first and second operation was a mean of 43.3 days (range, 2-103 d). RESULTS At the primary surgery, 29 patients (80.6%) had a follicular variant of papillary carcinoma, 6 (16.7%) had follicular carcinoma, and 1 (2.8%) had Hürthle cell carcinoma. Of these, 14 had multifocal disease. In the completion lobe, 20 patients (55.6%) had evidence of thyroid carcinoma. There was a 0% incidence of RLN injury, and the mean pre- and post-completion thyroidectomy serum calcium was 8.9 mg/dL and 8.6 mg/dL, respectively. There was one postoperative hematoma, requiring re-exploration. Five patients (13.9%) had a transient postoperative serum calcium (Ca) <8.0 mg/dL, with one being symptomatic. None required vitamin D or prolonged calcium supplementation. CONCLUSIONS When completion thyroidectomy is necessary for the treatment of thyroid malignancy, the procedure can be performed safely with low morbidity and is effective for diagnosing and removing occult disease in the remaining thyroid.

Abstract
BACKGROUND AND PURPOSE In 1998, we developed a technique for video-assisted thyroidectomy (VAT) which we proposed using also in patients with small low-risk papillary thyroid carcinomas (PTC). In some cases, enlarged lymph nodes are incidentally found at surgery for PTC. These nodes should be removed because of the risk of metastases. In this paper, we report on the patients in whom we removed enlarged central neck lymph nodes during VAT for PTC and discuss the feasibility and safety of video-assisted central neck lymph node dissection (VALD). PATIENTS AND METHODS The procedure is performed by a totally gasless video-assisted technique through a single 1.5-to 2.0-cm skin incision above the sternal notch. Dissection is performed under endoscopic vision using a technique very similar to that of conventional surgery. Only enlarged lymph nodes were removed and sent for frozen section examination (FS). No other dissection was performed in case of negative FS. Five patients underwent VALD during VAT for PTC. RESULTS The mean number of lymph nodes removed was 2.4. No metastases were found at FS or final histology examination. Postoperative complications included two transient postoperative hypocalcemias. No evidence of residual or recurrent disease was observed at postoperative follow-up. The cosmetic result was excellent. CONCLUSION Our experience demonstrates that removal of central compartment lymph nodes is feasible and safe. Perhaps also complete central neck lymph node dissection can be performed. Some doubts persist about the oncologic validity of this approach. For definitive conclusions, larger series and comparative studies are necessary.

Abstract
Primary malignant mediastinal seminomas (PMMS) are rare tumors accounting for 1-6% of all mediastinal tumors. PMMS mostly affect young men, arising from primordial germ cells that abnormally migrate from the ectoderm of the yolk sac to the gonadal region. They are clinically and biologically distinct from primary testicular tumors and seem to have a worse prognosis. Due to the rarity of the disease, the choice of treatment is a matter of debate. Literature data do not show any association between this kind of tumor and malignant Schwannoma or thyroid carcinoma. In this report we describe the case of a patient affected by PMMS and 12 yr later by a malignant brachial plexus Schwannoma and papillary thyroid carcinoma (PTC). Since both mediastinal seminoma and Schwannoma were treated with surgery followed by local radiotherapy, we were not able to ascertain if either PTC or Schwannoma had been induced by radiotherapy or represented a casual neoplastic association.

Abstract
BACKGROUND Retinoic acid (RA) has antiproliferative as well as redifferentiating effects in thyroid cancers. Similar effects have been seen with phenylacetate (PA) therapy. These observations prompted us to evaluate the potential antiproliferative effects of the combination of RA and PA in follicular thyroid cancer. METHODS Three follicular cell lines were treated in vitro with varying concentrations of all-trans RA or PA alone or in combination. Growth was measured by dimethyl-thiazol-diphenyltetrazolium bromide assays. RESULTS RA (1-2.5 micromol/L) and PA (1-10 mmol/L) alone inhibited cell growth in a time- and dose-dependent manner, with maximum effect at 5 days. The combination of RA and PA had synergistic antiproliferative effects. In the FTC-133 cell line, RA alone (2.5 micromol/L) inhibited growth 16% and PA alone (10 mmol/L) inhibited growth 35% versus controls, whereas the combination of the 2 inhibited growth by 60% at 5 days (P < .005). Similar results were seen with FTC-236 and FTC-238 cell lines. CONCLUSIONS Our results support that RA and PA have antiproliferative effects in follicular thyroid cancer and are synergistic. The combination of RA and PA may be beneficial in the treatment of advanced thyroid cancers for which conventional therapy fails or as an adjuvant to radioactive iodine therapy in aggressive tumors.

Abstract
Patients with Hürthle cell carcinoma (HCC) of the thyroid often have aggressive tumors and generally have a worse prognosis than those with papillary or follicular thyroid carcinomas. A total thyroidectomy with ipsilateral central neck lymphadenectomy and a modified radical neck dissection, if central or lateral nodes are positive, are indicated for HCC. The completeness of this procedure should be assessed by radioiodine scan 3 to 4 months after surgery. Any thyroid remnant should be ablated with radiolabeled iodine 131 to eliminate all tissue at risk and to facilitate the use of serum thyroglobulin in surveillance for tumor recurrence. Fewer than 10% of these cancers take up radioiodine. Recurrent disease is treated surgically with good palliation and appreciable prolongation of life. Local excision and neck dissection for recurrent neck disease or pulmonary wedge resection for lung metastasis has been shown to be effective. All patients with HCC should be given thyroid hormone because most of these tumors have thyrotropin receptors. External beam radiation may be considered for patients with unresectable disease, but this is considered palliative.
