ABSTRACT

Introducción: En las últimas décadas la incidencia del cáncer tiroideo en el curso de la enfermedad nodular se ha incrementado debido a las novedosas técnicas de diagnóstico; sin embargo, la tasa de mortalidad se ha mantenido muy baja. Objetivo: Evaluar las características clínicas, epidemiológicas y quirúrgicas de pacientes con afecciones nodulares tiroideas. Métodos: Se realizó un estudio descriptivo observacional de cohorte prospectivo, longitudinal con los pacientes operados de afecciones tiroideas durante el período comprendido entre enero del 2008 y diciembre del 2018. El universo y la muestra quedaron constituidos por 467 pacientes que cumplieron con los criterios de inclusión. Resultados: Predominaron el sexo femenino (89,5 por ciento) y el grupo etario de 45-60 años (29,5 por ciento). Asociaron comorbilidades 338 pacientes y algún factor de riesgo de malignidad (6,2 por ciento). Un total de 174 pacientes manifestaron síntomas y 264 mostraron algún signo. Predominaron los reportes ecográficos (TI-RADS) y citológicos (Bethesda) tipo II (54,3 por ciento) y (55,5 por ciento), respectivamente. La hemitiroidectomía fue el procedimiento más realizado (59,9 por ciento) y la disfonía la complicación más encontrada (1,9 por ciento). Conclusiones: El diagnóstico oportuno del cáncer tiroideo en el curso de una enfermedad nodular contribuye a individualizar todas las decisiones terapéuticas atendiendo a las características de cada paciente y sus circunstancias(AU)


Introduction: In recent decades, the incidence rates of thyroid cancer in the course of nodular disease has increased due to novel diagnostic techniques; however, the mortality rate has remained very low. Objective: To evaluate the clinical, epidemiological and surgical characteristics of patients with nodular thyroid disease. Methods: A descriptive, observational, of prospective cohort, longitudinal and observational study was conducted with patients operated on for thyroid disorders during the period from January 2008 to December 2018. The study universe and sample consisted of 467 patients who met the inclusion criteria. Results: The female sex (89.5 percent) and the age group 45-60 years (29.5 percent) predominated. Comorbidities were present in 338 patients, as well as some risk factor for malignancy in 6.2 percent. A total of 174 patients manifested symptoms and 264 showed some sign. There was a predominance of echography (TI-RADS) and cytology (Bethesda) type II reports, accounting for 54.3 percent and 55.5 percent, respectively. Hemithyroidectomy was the most performed procedure (59.9 percent), while dysphonia was the most encountered complication (1.9 percent). Conclusions: Timely diagnosis of thyroid cancer in the course of nodular disease contributes to individualizing all therapeutic decisions considering the characteristics of each patient and their circumstances(AU)

ABSTRACT

Objective: To analyze the morbidity and mortality trends of thyroid cancer in China from 1990 to 2019, explore the causes of the trends, and predict morbidity and mortality in the future. Methods: The morbidity and mortality data of thyroid cancer in China from 1990 to 2019 were collected from the 2019 Global Burden of Disease database. The Joinpoint regression model was used to describe the change trends. Based on the morbidity and mortality data from 2012 to 2019, a grey model GM (1,1) was constructed to predict the trends in the next ten years. The model was tested by the posterior error method and residual test method. Results: In all populations, men and women, the AAPC values of the crude morbidity rates were 4.15% (95%CI: 3.86%-4.44%, P<0.001), 5.98% (95%CI: 5.65%-6.31%, P<0.001) and 3.23% (95%CI: 2.94%-3.53%, P<0.001) respectively, the AAPC values of age-standardized morbidity rates were 2.47% (95%CI: 2.12%-2.83%, P<0.001), 3.98% (95%CI: 3.68%-4.29%, P<0.001), 1.65% (95%CI: 1.38%-1.93%, P<0.001), the AAPC values of crude mortality rates were 2.09% (95%CI: 1.92%-2.25%, P<0.001), 3.68% (95%CI: 3.45%-3.90%, P<0.001), 0.60% (95%CI: 0.50%-0.71%, P<0.001). The age-standardized mortality rates in men showed a fluctuating trend of first decrease (1990-1994), then increase (1994-2012), and then decrease (2012-2019) (AAPC=1.35%, 95%CI: 1.16%-1.53%, P<0.001). The age-standardized mortality rate in women continuously decreased (AAPC=-1.70%, 95%CI: -1.82%- -1.58%, P<0.001). The GM (1,1) models can be used for medium and long-term predictions. The results of the residual test show that the average relative error values of all models are less than 10.00%, the prediction accuracy values are more than 80.00%, and the prediction effects are good. The results of the posterior error method show that all the prediction results are good except the qualified prediction of the age-standardized morbidity rate in men. In 2029, the crude morbidity rates would increase to 3.57/100 000, 2.78/100 000, and 4.40/100 000, respectively, and the age-standardized incidence rates would increase to 2.38/100 000, 1.89/100 000, and 2.88/100 000, respectively, the crude mortality rates would increase to 0.57/100 000, 0.62/100 000 and 0.53/100 000, and the age-standardized mortality rates would decrease to 0.33/100 000, 0.42/100 000 and 0.27/100 000 in all population, men and women in China. Conclusions: The overall, gender- specific age-standardized mortality rates showed downward trends in the last decade or so, and the prediction results showed that it might further decline. However, the crude morbidity rates, age-standardized and crude mortality rates have been on the rise, and the population aging is becoming increasingly serious in China, which requires close attention and targeted prevention and control measures.

ABSTRACT

RESUMEN Introducción: la citología con aguja fina se mantiene como el estudio fundamental ante un nódulo tiroideo, pero el diagnóstico de neoplasia folicular es aún su punto débil para definirlo. Se mantiene como conducta su extirpación quirúrgica para alcanzarlo. Objetivo: determinar la correlación citopatológica en las neoplasias foliculares del tiroides. Materiales y métodos: se realizó un estudio prospectivo y descriptivo que incluyó a 80 pacientes operados con diagnóstico citológico de neoplasia folicular del tiroides, en el Hospital "Comandante Faustino Pérez" de la ciudad de Matanzas, de marzo del 2012 a febrero del 2016. Se evaluaron las variables: edad, sexo, tamaño, localización, número de nódulos y diagnóstico histológico definitivo. Resultados: predominaron las lesiones benignas con 56 para el 70 % dentro de ellas, los bocios multinodulares con 33,75 % y los adenomas foliculares con el 31,25 %. Los tumores malignos ocuparon el 30 %. El carcinoma papilar, variedad folicular con 12 para el 15 %, seguido del carcinoma papilar clásico con 10 para el 12,50 %. Conclusiones: el porcentaje de malignidad de este estudio fue del 30 % con predominio del carcinoma papilar variedad folicular y el carcinoma papilar clásico. Entre las lesiones benignas predominaron los bocios multinodulares y los adenomas foliculares (AU).


ABSTRACT Introduction: fine needle cytology is still the main study against a thyroidal nodule, but the follicular neoplasia diagnosis is still its weak point to define it. The surgical removal keeps being used to reach it. Objective: to determine the cytopathological correlation in follicular thyroid neoplasia. Materials and methods: a prospective, descriptive study was carried out including 80 patient with diagnosis of follicular thyroid neoplasia in the Hospital "Comandante Faustino Pérez" of Matanzas, who underwent a surgery from March 2012 to February 2016. The assessed variables were age, sex, size, location, quantity of nodes and final histological diagnosis. Results: benign lesions predominated, with 56 for 70 %; among them, multinodular goiters with 33.75 % and follicular adenomas with 31.25 %. Malignant tumors were 30 %: papillary carcinoma, follicular variety with 12 for 15 %, followed by the classical papillary carcinoma with 10 for 12.50 % Conclusions: the malignity percent of this study was 30 % with the predominance of the papillary carcinoma, follicular variant and the classic papillary carcinoma. Multinodular goiters and follicular adenomas predominated among the benign lesions (AU).

ABSTRACT

El cáncer de tiroides es la neoplasia maligna más frecuente del sistema endocrino, siendo el más frecuente el cáncer bien diferenciado (papilar y folicular). El propósito de este trabajo es recoger nuestra experiencia clínica en el manejo y resultados del cáncer diferenciado de tiroides. Material y métodos: Estudio retrospectivo de 50 casos de pacientes con tumores malignos tiroideos, intervenidos de tiroidectomía total por nuestro servicio durante el periodo de 2015 a 2018. Se han recogido variables clínico-epidemiológicas que han sido procesadas con el programa SPSS versión 25. Se realiza estudio descriptivo y de asociación entre las diferentes variables según el tipo anatomo-patológico de tumor. Se analiza la probabilidad de recidiva del cáncer de tiroides y se utiliza el modelo de Cox para ajustar los efectos sobre la recidiva de diferentes variables en un modelo predictivo. Resultados: El 84% eran carcinoma papilar y 16% eran carcinoma folicular. Al finalizar el periodo de seguimiento (72 meses), el 14% presentaba recidiva, y habían fallecido el 8%. El carcinoma folicular fue el que mostró menor supervivencia. El tiempo medio sin recaída, fue de 129 meses. Las variables que influían en la supervivencia fueron: existencia de complicaciones en el postoperatorio, valor de tiroglobulina y antitiroglobulina y TIRADS. Conclusión: Coincidimos con el resto de autores en los aspectos epidemiológicos y clínicos. El carcinoma papilar es el más frecuente y tiene mejor pronóstico. Entre los factores que influyen en la supervivencia destacan el sexo y el tipo anatomo-patológico. Otros factores a considerar son: la existencia de complicaciones en el postoperatorio, la categoría TIRADS previa al tratamiento, y los valores de tiroglobulina y antitiroglobulina en los controles postoperatorios. (AU)


Thyroid cancer is the most frequent malignant neoplasm of the endocrine system, with well-differentiated cancer (papillary and follicular) being the most frequent. The purpose of this work is to collect our clinical experience in the management and results of well-differentiated thyroid cancer. Material and methods: Retrospective study of 50 cases of patients with malignant thyroid tumors, who underwent total thyroidectomy by our service during the period from 2015 to 2018. Clinical-epidemiological variables were collected and processed using the SPSS version 25 program. We have conducted a descriptive and association study between different variables according to anatomo-pathological tumor type. The probability of recurrence of thyroid cancer is analyzed and Cox model is used to adjust the effects on recurrence of different variables in a predictive model. Results: 84% were papillary carcinoma, and 16% were follicular carcinoma. At the end of the follow-up period (72 months), 14% had recurrence, and 8% had died. Follicular carcinoma showed the lowest survival. The mean time without relapse was 129 months. The variables that influenced survival were existence of postoperative complications, thyroglobulin and antithyroglobulin value, and TIRADS. Conclusion: We agree with the rest of the authors in the epidemiological and clinical aspects. Papillary carcinoma is the most frequent and has a better prognosis. Among the factors that influence survival, sex and anatomo-pathological type stand out. Other factors to consider are the existence of complications in the postoperative period, TIRADS category prior to treatment, and thyroglobulin and antithyroglobulin values in postoperative controls.

ABSTRACT

INTRODUCTION@#The impact of noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) on the risk of malignancy (ROM) in fine-needle aspiration cytology (FNAC) per The Bethesda System for Reporting Thyroid Cytopathology has not been well reported in Singapore.@*METHODS@#We retrospectively identified 821 thyroid nodules with preoperative FNAC from 788 patients out of 1,279 consecutive thyroidectomies performed between January 2010 and August 2016 in a tertiary general hospital in Singapore. Possible cases of NIFTP were reviewed for reclassification and the impact of NIFTP on ROM was analysed.@*RESULTS@#The incidence of NIFTP was 1.2% (10 out of 821). If NIFTP is considered benign, ROM in Bethesda I through VI were 8.6%, 3.5%, 26.3%, 20.0%, 87.7%, 97.0% versus 8.6%, 4.2%, 28.1%, 26.7%, 89.2% and 100% if NIFTP is considered malignant. Eight patients with NIFTP had follow-up of 15 to 110 months. One had possible rib metastasis as evidenced by I131 uptake but remained free of structural or biochemical disease during a follow-up period of 110 months. None had lymph node metastasis at presentation, nor locoregional or distant recurrence.@*CONCLUSION@#Classifying NIFTP as benign decreased ROM in Bethesda II through VI, but the benignity of NIFTP requires more prospective studies to ascertain. The impact of NIFTP on ROM in our institution also appears to be lower than that reported in the Western studies.

ABSTRACT

ABSTRACT Objective: The objective of the study was to develop an association between clinicopathologic and sonographic features of patients with papillary thyroid microcarcinoma and the prevalence of lymph node metastasis. Subjects and methods: Clinicopathologic and sonographic features of 415 patients of papillary thyroid microcarcinoma with (n = 102) or without (n = 313) lymph node metastasis were retrospectively reviewed. The thickness of the lymph node ≥ 6 mm with intra-lymph nodal occupying lesions considered lymph node metastasis. Also, it was considered metastasis if lymph node perfusion or blood flow defect was found with any thickness size. Univariate following multivariate analysis was performed for the prediction of sonographic features and clinicopathologic factors for the prevalence of lymph node metastasis. Results: Male gender ( p = 0.041), age < 45 years ( p = 0.042), preoperative calcitonin > 65 pg/ mL ( p = 0.039), nodule size > 5 mm in diameter ( p = 0.038), bilaterality ( p = 0.038), tumor capsular invasion ( p = 0.048), cystic change ( p = 0.047), and hyper vascularity ( p = 0.049) of thyroid nodules were associated with lymph node metastasis. Also, thyroid nodules 5 mm and more in diameter may have high aggressiveness. Conclusion: These data helped the surgeon for individualized treatment in thyroid carcinoma and avoid unnecessary prophylactic surgery of the lymph node.

ABSTRACT Introduction: Thyroid cancer represents 1% of the total of all kinds of cancer. Its incidence seems to increase 4% every year, and at the present time it is the eighth more frequent cancer in women. Objective: to determine the clinical epidemiological behaviour of the patients who underwent thyroid cancer surgery. Materials and methods: a retrospective, observational and descriptive study was carried out in all the patients who were admitted in the service of General Surgery of the University Hospital "Comandante Faustino Pérez Hernández" with thyroid cancer, in the period from January 1993 to December 2018. A data collector model was used with the variables of interest for the study and the data were presented by charts of frequency, numbers and percent. Results: thyroid cancer was more frequent in the age group of 31 to 50 years; the female sex prevailed; the most frequent variety was the histological papillary one, and the right lobe was the most affected. Conclusions: thyroid cancer is more frequent in relatively young, female patients; the clinical form of solitary nodule with normal thyroid function and papillary carcinoma the most frequent variety (AU).

ABSTRACT

RESUMEN Con el objetivo de describir los casos de cáncer de tiroides en Manizales, Colombia, se realizó un estudio que describe las características de los pacientes y de los tumores según el tamaño, la lateralidad, la focalización, el compromiso ganglionar, la invasión contigua, la metástatisis y la estadificación TNM. Se analizaron 672 casos, el 84,8% de ellos fueron mujeres entre 40 y 64 años. El 34,1% de los casos fueron diagnosticados en estadios tempranos y el 15% de los tumores tuvieron un tamaño <20 mm. El compromiso ganglionar y de tejidos adyacentes estuvo presente en el 33% y el 3% de los casos, respectivamente. Se registró un 1% de metástasis a distancia. El carcinoma papilar se presentó en el 82% de los casos. El cáncer de tiroides en Manizales es más frecuente en mujeres adultas; el estadio temprano y el tamaño tumoral sugieren mejora en la detección temprana.


ABSTRACT A study was conducted to describe the cases of thyroid cancer in Manizales, Colombia. This study describes the characteristics of patients; and tumors according to size, laterality, focalization, nodal involvement, contiguous invasion, metastasis and TNM staging. A total of 672 cases were analyzed, 84.8% of which were women between 40 and 64 years of age. From the population, 34.1% were cases diagnosed in early stages and 15% of the tumors were >20 mm in size. Nodal and adjacent tissue involvement was present in 33% and 3% of the cases, respectively. Distant metastasis was documented in 1% of the cases. Papillary carcinoma was present in 82% of cases. Thyroid cancer in Manizales is more frequent in adult women. Tumor size and being at the early stages are factors that suggest improvement in early detection.

ABSTRACT

Background: In Chile, Thyroid cancer (TC) is included in a list of diseases that have a guaranteed access to treatment, endorsed by the Ministry of Health. The care burden of the disease will depend on its incidence. Aim: To estimate the incidence of TC in Chilean patients with access to thyroid surgery and describe its histopathological characteristics. Material and methods: Analysis of the registry of all thyroidectomies performed at a private oncological clinic in Metropolitan Santiago, between 2016 and 2018. Incidence was estimated the number of persons affiliated to an insurance system managed by the same clinic, separated by age and gender. Results: TC adjusted incidence varied from 60.8 cases per 100,000 persons/year in 2016 to 48.7 cases per 100,000 persons/year in 2018. The proportion of microtumors was 34% when the diameter of all foci was considered. Papillary and follicular carcinomas were the pathological diagnoses in 96 and 2% of cases respectively. Twenty-one percent of tumors had extra-thyroidal invasion. Conclusions: The TC incidence herein reported is higher than the figure of 7.9 cases per 100,000 persons/year reported by us in 2014. This difference could be due to a true increase in the incidence of TC, following worldwide trends or to differences in the methods used in both studies.

ABSTRACT

RESUMEN Introducción: El fenómeno de las neoplasias primarias múltiples se ha descrito en cabeza y cuello, de forma metacrónica y sincrónica. Caso clínico: Hombre de 54 años, piel negra y procedencia rural con carcinoma escamoso de laringe T3N1M0, etapa III, que en disección de cuello se encontró incidentalmente metástasis ganglionar de carcinoma papilar de tiroides, sin evidencia clínica de lesión tiroidea. Luego se realizó ecografía y gammagrafía de la glándula cuyos resultados no mostraron alteración alguna. Conclusiones: El carcinoma de tiroides es hallado incidentalmente en el espécimen resecado después de cirugía por cáncer de cabeza y cuello en 0,3 - 1,9 por ciento de los pacientes. Por este motivo debe evaluarse bien la glándula tiroides previa cirugía de cabeza y cuello(AU)


ABSTRACT Introduction: The phenomenon of multiple primary neoplasms has been described in the head and neck in a synchronous and metachronous way. Clinical case: A 54 years old man, black skin and rural origin with a T3N1M0 larynx squamous cell carcinoma, stage III that in a neck dissection was incidentally found a node metastasis of papillary thyroid carcinoma, without clinical evidence of thyroid lesion. This was followed by ultrasound and nuclear scan of the gland, whose results did not show any alteration. Conclusions: The thyroid carcinoma is found incidentally in the resected specimen after surgery by head and neck cancer in 0.3 - 1.9 percent of patients. The thyroid gland must be well assessed after head and neck surgery(AU)

ABSTRACT

Objetivo: Descrever o perfil clínico-epidemiológico de casos hospitalares de câncer primário de tireoide no Brasil. Métodos: Estudo descritivo dos casos informados pelos registros hospitalares de câncer que tiveram primeira consulta para tratamento no período 2000-2016 e cujo acompanhamento foi realizado pela instituição do registro informante. Resultados: Dos 52.912 casos, 83,4% eram femininos e 96,9% eram carcinomas diferenciados. Apresentaram menor tempo mediano para diagnóstico os casos anaplásicos (11 dias) e os residentes da região Sul do país (5 dias). O tratamento foi iniciado em até 60 dias em 88,8% dos casos que chegaram à instituição do registro sem diagnóstico e em 34,9% dos que chegaram com diagnóstico. Conclusão: Os achados são consistentes com a epidemiologia do câncer de tireoide, com predominância do sexo feminino e do carcinoma diferenciado. A análise do tempo para início do tratamento sugere dificuldades de acesso para aqueles que chegaram às instituições dos registros com diagnóstico.


Objetivo: Describir el perfil clínico y epidemiológico de los casos de cáncer de tiroides en Brasil. Métodos: Estudio descriptivo de casos reportados por los registros hospitalarios de cáncer que tuvieron su primera consulta de tratamiento en el período 2000-2016 y el monitoreo fue realizado por la institución del registro. Resultados: De los 52.912 casos, 83,4% eran mujeres y 96,9% era de carcinomas diferenciados. El tiempo promedio hasta el diagnóstico fue menor en los anaplásicos (11 días) y en la región Sur (5 días). El tratamiento se inició dentro de los 60 días en 88.8% de los casos que llegaron a la institución de registro sin diagnóstico y en 34.9% de los que llegaron con diagnóstico. Conclusión: Los resultados son consistentes con la epidemiología del cáncer de tiroides, con predominio del sexo femenino y carcinomas diferenciados. El análisis del tiempo de tratamiento sugiere dificultades de acceso para casos que llegaron con diagnóstico.


Objective: To describe the clinical and epidemiological profile of primary thyroid cancer hospital cases in Brazil. Methods: This is a descriptive study of cases held on hospital cancer records who had their first consultation for treatment in the period 2000-2016 and who were monitored by the hospitals providing those records. Results: Of the 52,912 cases, 83.4% were female and 96.9% were differentiated carcinoma cases. The median time to diagnosis was shorter for anaplastic cases (11 days) and for those living in Brazil's Southern region (5 days). Treatment was initiated within 60 days in 88.8% of cases that arrived at the hospitals without diagnosis and in 34.9% of those who arrived with diagnosis. Conclusion: The findings are consistent with thyroid cancer epidemiology, with a predominance of female cases and differentiated carcinomas. Analysis of time-to-treatment suggests access difficulties for those who already had diagnosis when they arrived at the hospitals.

ABSTRACT

Introducción: El gen FOXE1 (Forkhead box E1) codifica para un factor de transcripción involucrado en la morfogénesis tiroidea. El cáncer papilar de tiroides (CPT) se ha asociado con polimorfismos (SNP) de FOXE1 rs1867277 y rs965513 en población asiática y europea. Nuestro objetivo fue investigar la frecuencia y asociación de SNP rs1867277 y rs965513 con CPT y el riesgo de recurrencia de CPT en sujetos chilenos. Métodos: Se reclutaron sujetos con y sin CPT, se describieron sus características epidemiológicas y la forma de presentación clínica (AJCC VIII y MINSAL 2013). Se aisló ADN de leucocitos periféricos y evaluó ambos SNP mediante PCR-HRM y secuencia. Se compararon las frecuencias alélicas y genotípicas entre casos CPT y controles, y entre pacientes CPT de distintos riesgos de recurrencia. Se compararon frecuencia y se estimó el riesgo con test de Fisher y cálculo de odds-ratio (OR). Resultados: De los 184 sujetos, 156 (85%) eran mujeres, edad 39,3±12,3 años; 90 con CPT y 94 sin CPT 26 (28,9%) pacientes eran de riesgo muy bajo, 45 (50%) bajo, 16 (17,8%) intermedio y 3 (3,3%) alto según MINSAL 2013. En relación a la frecuencia de alelo menor (MAF) calculada en sujetos control y CPT, fue 31,7% y 24,5% (SNP rs965513), y 36,7% y 30,1% 8 (rs1867277), respectivamente (p NS). Tampoco fueron diferentes las MAF calculados y comparados entre pacientes con CPT de riesgo bajo e intermedio/alto. Sin embargo, la combinación de los genotipos rs1867277GG y rs965513AA se asoció a mayor riesgo de CPT. Conclusiones: En pacientes chilenos, se describe una frecuencia MAF de los SNP rs1867277 y rs965513 cercana a un 30%, las cuales no se asocian a CPT ni riesgo de recurrencia, sin embargo, sujetos con una combinación genotípica particular podrían tener mayor riesgo de CPT.


FOXE1 gene (Forkhead E1 box) codes for a transcription factor involved in thyroid morphogenesis. Papillary thyroid cancer (PTC) has been associated with FOXE1 polymorphisms (SNPs) rs1867277 and rs965513 in Asian and European population. Our aim was to investigate the frequency and the association of SNPs rs1867277 and rs965513 with PTC and the risk of recurrence of PTC in Chilean subjects. Methods: We recruited subjects with and without PTC. In those with PTC, their epidemiological characteristics and clinical features presentation are described according to AJCC VIII and MINSAL 2013 scales. Peripheral leukocyte DNA was isolated and both SNPs were evaluated using PCR-HRM and sequencing. Allelic and genotypic frequencies were compared between PTC cases and controls, and between PTC patients with different recurrence risks. Results: Of the 184 subjects, 156 (85%) were women, age 39.3 ± 12.3 years; 94 (51%) without PTC and 90 with PTC (49%): 26 (28.9%) patients had very low, 45 (50%) low, 16 (17.8%) intermediate and 3 (3.3%) high risk of recurence according to MINSAL 2013. Regarding the minor allele frequency (MAF) calculated on control and PTC subjects, was 31.7% and 24.5% (SNP rs965513), and 36.7% and 30.1% (rs1867277), respectively (p NS). In patients with PTC, MAFs were not different between patients with low and intermediate/high risk PTC. However, the combination of rs1867277GG and rs965513AA genotypes were associated with an increased risk of PTC. Conclusions: In Chilean patients, the MAF frequency of SNPs rs1867277 and rs965513 is near 30%, and they are are not associated with PTC or its risk of recurrence. However, subjects with a particular genotypic combination may have an increased risk of PTC.

ABSTRACT

Introducción: El diagnóstico y tratamiento de pacientes con nódulo de tiroides son un desafío clínico, instrumental, imagenológico y patológico, y a pesar de que no representan un problema de salud en Cuba, afecta a un grupo importante de la población, fundamentalmente en edad laboral. Objetivo: Determinar las características clínicas, patológicas y epidemiológicas de pacientes con carcinoma bien diferenciado de tiroides. Métodos: Se realizó un estudio descriptivo y transversal de 30 pacientes con cáncer bien diferenciado de tiroides, operados en el Hospital Oncológico Conrado Benítez García de Santiago de Cuba, desde enero de 2014 hasta julio de 2017 y que recibieron tratamiento oncoespecífico, para lo cual se revisaron las historias clínicas y los informes de biopsia de cada uno. Resultados: En la serie predominaron las mujeres de 40-49 años de edad, los afectados de piel mestiza y negra, el aumento de volumen de la glándula, los nódulos hipoecogénicos, el tumor papilar, además de la infiltración capsular y la permeabilización vascular entre los factores pronósticos histológicos más comunes. Conclusiones: Existen elementos clínicos, epidemiológicos e imagenológicos para diagnosticar un presunto carcinoma bien diferenciado de tiroides.


Introduction: The diagnosis and treatment of patients with thyroid node are a clinical, instrumental, imagenological and pathological challenge, and although they does not represent a health problem in Cuba, they affect an important populational group, fundamentally in working periods. Objective: To determine the clinical, pathological and epidemiological characteristics of patients with well differentiated carcinoma of thyroid. Method: A descriptive and cross-sectional study of 30 patients with well differentiated cancer of thyroid, operated in Conrado Benítez García Oncological Hospital belonging to Santiago de Cuba was carried out from January, 2014 to July, 2017 and who received onchospecific treatment , for which the medical records and the biopsy reports were reviewed from each patient. Results: In the series the 40-49 year-old women , those patients affected of mestizo and black skin, the increase of the gland volume, the hypoechogenic nodules and the papillary tumor prevailed, besides the capsular infiltration and the vascular permeabilization among the most common histological prognosis factors. Conclusions: Clinical, epidemiological and imagenological elements exist to diagnose a presumed well differentiated carcinoma of thyroid.

ABSTRACT

ABSTRACT Objectives: We aimed to investigate the prevalence of the BRAF (V600E) mutation in consecutive cases of papillary thyroid carcinoma (PTC) in patients diagnosed and treated at the Hospital Sao Rafael (Salvador, BA, Brazil) and evaluate its association with clinical and pathological characteristics of PTC. Subjects and methods: We retrospectively enrolled in the study a total of 43 consecutive PTC patients who underwent total thyroidectomy. We performed DNA extraction from formalin-fixed paraffin-embedded (FFPE) tumour tissue samples. Polymerase chain reaction (PCR) and direct sequencing were used to determine BRAF (V600E) mutation status. Univariate and multivariate logistic regression analyses were employed to identify independent associations. Results: The prevalence of BRAF (V600E) mutation was 65.1% (28/43). A high frequency of older patients (p value: 0.004) was observed among the BRAF-mutated PTC group and, in contrast, a low frequency of concurrent Hashimoto's thyroiditis (HT) (p value: 0.011) was noted. Multivariate analysis confirmed that older age (OR: 1.15; 95% CI: 1.00 - 1.33; p value: 0.047) and HT (OR: 0.05; 95% CI: 0.006-0.40; p value: 0.005) were independent factors associated with BRAF (V600E) mutation. Conclusion: We found a high prevalence of BRAF (V600E) mutation in PTC cases. Older age and no concurrent HT were independently associated with BRAF (V600E) mutation.

ABSTRACT

OBJETIVO Describir la tendencia de la prevalencia y mortalidad de cáncer de tiroides registrada en el Ministerio de Salud de Perú. MÉTODOS Se realizó un estudio descriptivo de tendencias con datos secundarios, obtenidos de una fuente de información pública de Perú. Se evaluó el registro de codificación CIE 10: C73.0, por grupo de edad, año y región. Se calcularon las tasas estandarizadas de la prevalencia (periodo 2005 a 2016) y mortalidad (periodo 2005 a 2015) por regiones y año de estudio. RESULTADOS Durante el periodo 2005-2016 se registraron 19 513 casos de cáncer de tiroides. El grupo etario con mayor frecuencia fue de 30 a 59 años (57,7%). La prevalencia incrementó de 4,7 a 15,2 casos por 100 000 habitantes en el periodo 2005-2016 y la región de la costa fue la que presentó mayor ascenso. Asimismo, se registraron 1596 muertes por cáncer de tiroides (periodo 2005 a 2015) con mayor frecuencia en mayores de 60 años (75,5%). La tasa estandarizada de mortalidad por 100 000 habitantes aumentó de 0,67 en 2005 a 0,72 en 2015, siendo la región de la sierra la de mayor incremento. CONCLUSIONES La prevalencia por cáncer de tiroides aumentó y la mortalidad se mantuvo constante en el periodo estudiado. Estos resultados animan a explorar factores sociales y de la población que hayan podido influir en ello; además de mejorar los registros poblacionales de esta y otras neoplasias en Perú.
