ABSTRACT

Objetivo: Avaliar o perfil epidemiológico de pacientes com diagnóstico de carcinoma diferenciado de tireoide. Métodos: Estudo analítico descritivo, realizado por meio da análise e da coleta de dados de 34 prontuários de pacientes em seguimento em um ambulatório de endocrinologia de um hospital público em São Paulo. Foram incluídos todos os pacientes em acompanhamento no ambulatório com diagnóstico de tumores diferenciados; foram excluídos os menores de 18 anos e/ou com diagnóstico de outras neoplasias de tireoide (que não tumores diferenciados). Resultados: A idade dos pacientes variou de 25 a 84 anos ao diagnóstico, com média de 51 anos, tendo sido representados por 32 mulheres (94,11%) e 2 homens (5,88%). A maioria dos tumores (41,17%) possuía tamanho entre 1 e 2cm. A maior parte dos pacientes tinha baixo risco de recorrência, e todos foram tratados cirurgicamente. Conclusão: O tumor diferenciado mais frequente é o subtipo papilífero. Sua prevalência se dá em mulheres, com média de idade ao diagnóstico de 51 anos. (AU)


Objective: To evaluate the epidemiological profile of patients with differentiated thyroid carcinoma. Methods: Th is i s a d escriptive, analytical study performed through the analysis and collection of data from 34 medical records of patients being followed in an endocrinology clinic of a public hospital in the city of São Paulo. All patients being followed at the outpatients' department with a diagnosis of differentiated thyroid carcinoma were included, and those under 18 and/or with diagnosis of other cancer of the thyroid (other than differentiated tumors) were excluded. Results: the patients' ages ranged from 25 to 84 years at diagnosis, an average of 51 years represented by 32 women (94.11%) and 2 men (5.88%). Most tumors (41.17 %) were between 1 and 2cm. Most patients showed low risk of recurrence, and all were surgically treated. Conclusion: The most frequent differentiated tumor was the papillary one. Its prevalence was on women, with an average age at diagnosis of 51 years. There were only two patients with recurrent disease, and one with metastasis to the lung that died. (AU)

ABSTRACT

ABSTRACT Objective: Recent data indicates an increasing incidence of thyroid cancer not accompanied by a proportional increase in mortality, suggesting overdiagnosis, which may represent a big public health problem, particularly where resources are scarce. This article aims to describe and evaluate the procedures related to investigation of thyroid nodules and treatment and follow-up of thyroid cancer and the costs for the Brazilian public health system between 2008 and 2015. Materials and methods: Data on procedures related to investigation of thyroid nodules and treatment/follow-up of thyroid cancer between 2008 and 2015 in Brazil were collected from the Department of Informatics of the Brazilian Unified Health System (Datasus) website. Results: A statistically significant increase in the use of procedures related to thyroid nodules investigation and thyroid cancer treatment and follow-up was observed in Brazil, though a reduction was noted for procedures related to the treatment of more aggressive thyroid cancer, such as total thyroidectomy with neck dissection and higher radioiodine activities such as 200 and 250 milicuries (mCi). The procedures related to thyroid nodules investigation costs increased by 91% for thyroid ultrasound (p = 0.0003) and 128% in thyroid nodule biopsy (p < 0.001). Costs related to treatment and follow-up related-procedures increased by 120%. Conclusion: The increase in the incidence of thyroid cancer in Brazil is directly associated with an increased use of diagnostic tools for thyroid nodules, which leads to an upsurge in thyroid cancer treatment and followup-related procedures. These data suggest that substantial resources are being used for diagnosis, treatment and follow-up of a potentially indolent condition.

ABSTRACT

ABSTRACT Objective Incidental thyroid cancers (ITCs) are often microcarcinomas; among them, the most frequent histotype is the papillary one. The purpose of this study was to evaluate the rate of papillary thyroid cancer (PTC) in patients thyroidectomized for benign multinodular goiter. Subject and methods We retrospectively evaluated the histological incidence of PTC in 207 consecutive patients who, in a 1-year period, underwent thyroidectomy for benign multinodular goiter. All patients came from an iodine-deficient area (Orleans, France) with three nuclear power stations located in the neighboring areas of the county town. Results Overall, 25 thyroids (12.1%) harbored 37 PTC, of which 31 were microcarcinomas. In these 25 PTC patients, mean age was 55 ± 10 years (range 30-75), female:male ratio 20:5 (4:1). In 10 patients (40% of 25 and 4.8% of 207), PTCs were bilateral, and in 7 (2 with microPTCs) the thyroid capsule was infiltrated. These 7 patients underwent central and lateral cervical lymph node dissections, which revealed lymph node metastases in one and two cases, respectively. Radioiodine treatment was performed in 7 cases. Neither mortality nor transient and permanent nerve injuries were observed. Four (16%) transient hypocalcaemias occurred as early complications. At last follow-up visit (mean length of follow-up 17.2 ± 3.4 months), all patients were doing well and free of any clinical local recurrence or distant metastases. Conclusion With a 12% risk that multinodular goiter harbors preoperatively unsuspected PTCs, which can have already infiltrated the capsule and that can be accompanied by PTC foci contralaterally, an adequate surgical approach has to be considered.

Resultados: Se realizaron 271 tiroidectomías totales. La indicación más frecuente fue por tamaño (51%). Los diagnósticos más frecuentes fueron carcinomas papilares (46%) e hiperplasia folicularcoloidea (37%). Se presentaron lesiones transitorias del nervio laríngeo recurrente en 2,9%, y lesiones persistentes en 2,5%. Hipocalcemia transitoria se presentó en el 25% de los pacientes. Discusión: Nuestra serie presenta resultados concordantes con la literatura, presenta una baja tasa de complicaciones, las cuales se observan principalmente en pacientes con vaciamiento cervical y/o en que se observaron 2 o menos paratiroides. Conclusiones: La tiroidectomía total es una técnica quirúrgica segura y nuestra experiencia presenta resultados concordantes a los publicados en la literatura internacional.


Introduction: Thyroidectomy is one of the most common surgeries performed in head and neck. There are few reports of experience in thyroidectomy in otolaryngology services in Chile. Aim: To analyze the clinical experience with total thyroidectomy performed in the service of ENT and Head and Neck Surgery of our hospital. Material and method: Retrospective descriptive study. Review of medical records of patients undergoing total thyroidectomy (TT) between 2010 and 2014 in our service records. Results: A total of 271 thyroidectomy were performed. The most frequent indication was size (51%). The most frequent diagnoses were papillary carcinomas (46%) and follicular colloid hyperplasia (37%). We found 2.5% of transient recurrent laryngeal nerve injury and 2.9% had persistent lesions. Transient hypocalcemia occurred in 25% of patients. Discussion: Our series shows good agreement with literature, it has a low rate of complications, which are mainly seen in patients with neck dissection and/or observed 2 or less parathyroid during surgery. Conclusions: Total thyroidectomy is a safe surgical technique, and our experience shows consistent results to those reported in international literature.

ABSTRACT

ABSTRACT INTRODUCTION: An ongoing discussion is found in medical literature about the reasons for changes in thyroid carcinoma incidence patterns over the last decades. OBJECTIVE: To analyze the clinical and pathological characteristics of thyroid carcinoma cases over a decade. METHODS: Cross-sectional study over an historical cohort. Medical records of 628 thyroid cancer cases in a single center were reviewed. 597 patients were included. Microcarcinoma cases were selected for a qualitative analysis phase, in which medical records were reviewed for better understanding of thyroid nodule and thyroid cancer diagnosis process. RESULTS: An increase in the proportion of cases with thyroid cancer diagnosis was observed throughout the decade; new cases were predominantly tumors of less than 2 cm, with histopathological signs of low aggressiveness. There was an increase in proportion of cases with malignant cytological results among microcarcinomas. CONCLUSION: There is a trend for increase in thyroidectomies due to cancer in this institution, with proportional increment of cases with histopathological characteristics indicative of early disease. Among microcarcinomas, there is an increasing group represented by cancer cases that were not incidentally diagnosed, related to an enhancement in preoperative diagnostic methods.


RESUMO Introdução: Persiste uma discussão na literatura sobre as razões para as mudanças no padrão de incidência do carcinoma de tireoide nas últimas décadas. Objetivo: Analisar as características clinicopatológicas dos casos de carcinoma de tireoide ao longo de uma década. Método: Estudo transversal sobre uma coorte histórica. Os registros médicos de 628 casos de câncer de tireoide de um único centro foram revisados. Foram incluídos 597 pacientes. Os casos de microcarcinoma foram selecionados para uma fase de análise qualitativa, na qual os registros médicos foram revisados para melhor entendimento do processo de diagnóstico do nódulo e do câncer. Resultados: Observamos um aumento na proporção de casos com diagnóstico de câncer de tireoide ao longo da década; os novos casos foram predominantemente de tumores < 2 cm, com sinais histopatológicos de baixa agressividade. Houve aumento na proporção de casos com resultado citológico maligno entre os microcarcinomas. Conclusão: Há uma tendência de crescimento nas tireoidectomias por câncer na nossa instituição, com incremento proporcional de casos com características histopatológicas indicativas de doença precoce. Entre os microcarcinomas, há um grupo em ascensão representado por casos com diagnóstico não-ocasional de câncer, relacionados à melhora dos métodos diagnósticos pré-operatórios.

ABSTRACT

Objective This study aimed to evaluate the results of thyroid surgeries with hospitalization periods shorter than 18 hours performed in a surgical endocrinology service, correlating these results with type of procedure, the definitive diagnosis and complications associated with the procedure.Subjects and methods The procedures performed, complications associated, hospitalization period, and relationships among these variables were assessed in consecutive patients subjected to different types of thyroid surgeries from January 1997 to March 2014 by the same group of surgeons. Data were analyzed by frequency, and the associations between the hospitalization period and other variables were analyzed using the Pearson chi-square test and Fisher’s exact test, using a multiple comparisons test with Bonferroni correction.Results Among the 3,411 surgeries performed, 799 of them were malignant neoplasia, 2,505 were benign tumors and 107 were Graves’ disease. The following procedures were performed: total thyroidectomy (1597 patients); total thyroidectomy with neck exploration (369 patients); lobectomy plus isthmectomy (1084 patients); total thyroidectomy complementation (145 patients); total thyroidectomy with neck dissection (84 patients); modified radical total thyroidectomy (13 patients); nodulectomy (11 patients); unresectable (9 patients); central neck dissection (48 patients); lateral neck dissection (38 patients); and others (13 patients). The following surgical complications, characteristic of the procedure: hemorrhage in 41 (1.2%) patients, hypoparathyroidism in 10 (0.3%) patients and recurrent laryngeal nerve (RLN) injury in 23 (0.7%) patients. Hospitalization shorter than 18 hours was observed in 97% of patients.Conclusion Thyroid surgery can be safely performed in virtually all patients on an overnight basis in specialized services.

ABSTRACT

Recientemente hemos reportado el déficit de selenio ambiental, y el estatus alterado de selenio medido como actividad de Glutatión Peroxidasa en población beneficiaria del Servicio de Salud de Osorno. Estos déficits se asocian a alteraciones funcionales y estructurales del tiroides que se correlacionan con la aparición de enfermedades tiroídeas benignas y cáncer tiroídeo. El objetivo de este trabajo es mostrar la tasa de tiroidectomías por cáncer y por enfermedades benignas que se presentan en las comunas que habitan la población beneficiaria del Servicio de Salud Osorno y llamar la atención sobre su posible asociación con el estatus alterado de selenio y la menor actividad de Glutatión Peroxidasa descrita previamente.


We have recently reported the lack of environmental selenium and the altered selenium status measured as deficient glutathione peroxidase (GPx) activity in the population affiliated to the Osorno Health Service. These deficits are associated to functional and structural abnormalities of the thyroid gland that correlates with the appearance of benign thyroid pathologies and thyroid cancer. The aim of this investigation is to show the rate of thyroidectomy associated with malign and benign disease in the communities associated to the Osorno Health Service and warn about their possible link with the poor amount of selenium in the environment and the altered function of the GPx enzyme, previously described.

ABSTRACT

Background: In childhood, thyroid cancer is uncommon and has a different biological behaviour than in adults. Aim: To analyze the surgical experience in thyroid cancer in children. Material and Methods: Review of medical records of patients aged 15 years or less with a thyroid cancer, operated in a Regional hospital between 1980 and 2007. Results: Six females and 2 males, aged 9 to 15 years, were operated in the study period. Five had a family history of thyroid diseases. Four had involvement of cervical lymph nodes at the moment of operation but none had systemic dissemination. All were euthyroid. A total thyroidectomy was performed in four patients. Cervical lymph node dissection was also performed in four patients. No immediate complications were recorded. One patient had a local relapse. Five patients were also treated with radioiodine. At the end of the follow up ranging from 108 to 320 months, all patients are asymptomatic. The pathological study disclosed a papillary carcinoma in seven and medullary carcinoma in one patient. Conclusions: Thyroid cancer in childhood has low mortality rates and surgical treatment is safe and effective.


El cáncer de tiroides en edad pediátrica es extremadamente infrecuente y tiene un comportamiento biológico diferente al adulto. El objetivo de este estudio es analizar la experiencia quirúrgica local en los últimos 27 años. Estudio de serie de casos describiendo las características anatomoclínicas, quirúrgicas, resultados del tratamiento y condición actual de los pacientes analizados mediante estadística descriptiva, realizando curva de sobrevida con método de Kaplan-Meier. Se intervinieron quirúrgicamente 8 pacientes por cáncer tiroideo, 6 del sexo femenino y 2 del masculino, con edad promedio de 13 años (9 a 15 años). Cinco tenían antecedentes familiares de patología tiroidea. Cuatro presentaron al momento del diagnóstico linfoadenopatías metastáticas cervicales, ninguno evidenció diseminación sistémica. Todos presentaban estado eutiroideo. El diagnóstico histopatológico concluyó carcinoma papilar en 7 casos y medular en 1. Se realizó tiroidectomía total en 4 pacientes. En 4 se practicó linfadenectomía cervical. No hubo complicaciones postoperatorias inmediatas. En 5 se complementó con radioyodoterapia. Una paciente desarrolló recidiva regional. Al término del estudio 7 llevan vida normal. Una paciente con carcinoma medular esporádico falleció siete años después de la cirugía, a causa de metástasis pulmonares y hepáticas. El seguimiento promedio de los cánceres papilares fue de 165 meses (108 a 320 meses). El cáncer de tiroides en edad pediátrica se asocia a una supervivencia prolongada, incluso en etapas avanzadas. La extensión de cirugía en los carcinomas papilares debe considerar factores pronósticos como tamaño y extensión del tumor primario, presencia o ausencia de metástasis y ciertamente, experiencia y buen juicio del equipo quirúrgico.

ABSTRACT

Introducción: En tiroidectomia total se están evaluando métodos de hemostasia distintos a la ligadura habitual. Objetivo: Presentar nuestra experiencia inicial en la tiroidectomia total sin ligaduras, al utilizar el método de sellado de vasos a través de Ligasure Precise®. Material y método: Se consignaron en forma prospectiva, los datos de 129 pacientes: Datos personales, fecha de operación, antecedentes mórbidos, síntomas, función tiroidea, examen físico, ecografía, punción con aguja fina, tipo de operación, cirujano, tiempo operatorio, estadía postoperatoria, débito de drenajes, biopsia intraoperatoria y definitiva, complicaciones. Se utilizó un p < 0.05 como significativo para los cálculos estadísticos. Resultados: Se realizaron 129 tiroidectomías entre Enero y Agosto del 2005. Se operaron 65 pacientes deforma tradicional y 64 con Ligasure. No hubo mortalidad operatoria. Edad promedio 42,7 y 46,9 para cada grupo (p >0.05). Biopsia definitiva informó carcinoma en 34 y 32 por ciento respectivamente. Hospitalización promedio de 2,63 días y 2,26 días (p 0.02). El débito de drenajes fue 78 ce para el grupo Ligasure y 63,2 ce para el grupo tradicional. Tiempo operatorio promedio de 94 minutos (grupo tradicional) y 92 minutos (Ligasure) (p= 0.6). Las complicaciones fueron hematoma (1 caso por grupo), Lesión de recurrente laríngeo (1 caso en el grupo de ligadura tradicional) e hipocalcemia transitoria (6 casos en el grupo Ligasure y 1 caso en el grupo control). Conclusión: La tiroidectomia con Ligasure Precise es un método cómodo para el cirujano y tan seguro como la tiroidectomia con ligaduras. Su aplicación, indicación y reales beneficios deben ser evaluados en el futuro con mayor número de casos.


Background: Traditionally, hemostasis during thyroidectomy is done using clamp ligation of vessels. There is a new hemostasis method based on thermal coagulation and pressure that be used in this type of surgery. Aim: To report the experience with Ligasure Precise® thermal hemostasis system. Material and methods: Prospective evaluation of patients subjected to thyroidectomy with or without the use of Ligasure®. The choice of patients for each type of hemostasis was not randomized. Operative time, surgical complications and postoperative evolution were assessed. Results: During the study period, 64 patients aged 43 + 15 years were operated using Ligasure® and 65, aged 47 + 12, were operated using traditional hemostasis. Among patients with and without use of Ligasure®, operative time was 92 and 94 minutes respectively (p=NS), wound drainage volume was 78 and 63 ml respectively (p=NS) and hospital stay was 2.6 and 2.3 days respectively (p = 0.02). One patient in each group had a hematoma, one patient operated with Ligasure® had a lesion of the recurrent laryngeal nerve. Six patients operated using Ligasure® and one operated without it, had transient hypocalcaemia. Conclusions: Ligasure® hemostasis system is safe in thyroidectomy.

ABSTRACT

Postsurgical hypothyroidism and its incidence has not been fully investigated. In this study, the incidence of hypothyroidism and its possible risk factors at Shariati Hospital was assessed. One hundred and two patients with benign thyroid diseases, who had undergone thyroidectomy, were investigated with regards to thyroid function profile during period of one year after the operation every three months with post-operative sample as the baseline. Hypothyroidism was developed in 36 patients [35.2%] on average 5 +/- 3.2 months after surgery. Factors such as increased age, operation type, histopathologic type, underlying disease, lymphocytic infiltration and use of levothyroxine before surgery were associated with the increased incidence of hypothyroidism. It seems that use of indicators such as Graves' disease and lymphocytic infiltration in pathologic specimens should be helpful in projecting the potential occurrence of hypothyroidism in patients undergoing thyroidectomy

ABSTRACT

Minimal access surgery in the thyroid compartment has evolved considerably over the past 10 years and now takes many forms. This study examined the feasibility and reliability of minimally invasive thyroid surgery in the management of small benign thyroid lesions. Sixty eight patients with small thyroid nodules admitted in Oncology Center, Mansoura University, Egypt, were enrolled in this prospective randomized trial. Patients were allotted in one of these procedures, minimally invasive video assisted thyroidectomy [MIVAT], or minimally invasive open thyroidectomy using the Sofferman technique of strap muscle transection. Exclusion criteria were nodules greater than 4 cm, presence of thyroiditis, and thyroid gland volume greater than 20 ml Preoperative diagnosis, operative time, blood loss, postoperative pain, complications and cosmetic outcome were all evaluated. MIVAT group included 35 patients and the Sofferman group included 33 patients. The main preoperative pathology was benign follicular lesion [70.5%] and the main postoperative final pathology was follicular adenoma [54.4]. Both groups were comparable regarding age, sex and extent of thyroid surgery. Operative time was significantly longer in MIVAT group [115.4 +/- 33.5 min] compared to the Sofferman group [65.6 +/- 23.7 min]. Postoperative course was significantly less painful in MIVAT group [P< 0.05]. Although patients in MIVAT group had smaller incisions [P <0.05], the cosmetic outcome in both groups was comparable. No long term complication was encountered in both groups. Two distinct approaches of minimally invasive thyroidectomy are now available and can be performed safely in selected patients. Despite some MIVAT advantages of less postoperative pain and slightly better cosmesis, minimally invasive open thyroidectomy offers an advantage of less operative time with comparable cosmetic results

ABSTRACT

Entre enero de 1978 y diciembre de 1996 se tratáron portadores de cáncer diferenciado de tiroides, 98 del tipo papilar y 4 del folicular. El grupo incluyó 86 mujeres y 16 hombres, con promedio de edad de 46,3 años (margen 9 a 80 años). De acuerdo a la clasificación de Meissner y Warren, 2 pacientes se estadificaron en estadio 0 (1,9 por ciento), 45 (44,1 por ciento) en estadio I;31 (30 por ciento) en estadio II; 17 (16,7 por ciento) en estadio IIIa; 1 (1,0 por ciento) en estadio IIIb y 6 (5,9 por ciento) en estadio IV. De los 102 pacientes, 100 fueron sometidos a tratamiento quirúrgico considerando el estadio de la enfermedad, tamaño del tumor primario y tipo histológico del carcinoma, priviligiando la cirugía conservadora en los cánceres papilares intracapsulares y la tiroidectomía total en los papilares extracapsulares y en los foliculares. Las complicaciones postoperatorias inmediata fueron 3 hematomas cervicales, 3 lesiones de nervio recurrente, 2 hipoparatiroidismo y otras menores, la mayoría de ellas secundarias a tiroidectomía total o casi total. No hubo mortalidad perioperatoria. La serie tiene un promedio de seguimiento de 74,1 meses. La sobrevida global es de 83,9 por ciento a 5 años y de 81,8 por ciento a 10 años, porcentaje que se mantiene hasta 20 años. En el estadio I la sobrevida es de 97,7 por ciento a 20 años

ABSTRACT

El cáncer de tiroides en la niñez es muy inusual, razón por la cual sus características clínicas son poco conocidas y su tratamiento suscita controversias. Presentamos 6 niños con cáncer de tiroides, 5 del tipo palpitar y 1 del tipo medular esporádico; 4 del sexo femenino y 2 del masculino, con edad promedio de 13 años (margen 9 a 15 años). Todos fueron tratados quirúrgicamente y la extensión de la cirugía varió según el tipo histológico y el estadio de la enfermedad. No hubo complicaciones postoperatorias inmediatas. Una paciente con cáncer papilar evolucionó con recidiva regional ipsilateral en 2 oportunidades y la niña con cáncer medular falleció por diseminación a los 84 meses de realizada la cirugía. El seguimiento promedio de los cánceres papilares es de 119 meses (margen 62 a 175 meses). Al cierre de esta revisión los 5 niños vivos se encuentran sin evidencias de enfermedad

ABSTRACT

Las alteraciones de la voz luego de la tiroidectomía son causadas por la lesión del Nervio Recurrente o Laríngeo Superior. Estos cambios en la voz también pueden ser originados por la modificación temporaria de los músculos pretiroideos. Objetivo: describir por qué luego de la tiroidectomía, aparecen cambios en la voz en pacientes con buena movilidad de las cuerdas vocales en controles pre y postoperatorios. Lugar de aplicación: Servicio de Cirugía Oncológica. Diseño: estudio prospectivo no randomizado. Población: 25 pacientes a los que se les realizó tiroidectomía total. Método: 25 pacientes fueron estudiados entre marzo de 1997 y junio de 1998. La edad promedio fue de 43 años, 22 fueron mujeres y 11 fumadores. Nueve casos fueron bocios multinodular, 9 adenomas bilaterales y 7 carcinomas diferenciados. Todos los pacientes fueron sometidos a tiroidectomías totales según técnica, con identificación y preservación del nervio recurrente y laríngeo superior. Durante la cirugía, los músculos pretiroideos no fueron cortados. Se realizó una fibrolaringoscopía en el pre y postoperatorio para controlar la movilidad de las cuerdas vocales. El análisis acústico de la voz reveló que la intensidad de la voz (Shimmer) creció entre los 2 y 4 meses, y se normalizó a los 6 meses. El tono fundamental de la voz (Fo) disminuyó entre los 2 y 4 meses, pero no se normalizó a los 6 meses. Conclusiones: los cambios de la voz luego de la tiroidectomía total ocurren. Los valores del Shimmer se normalizaron a los 6 meses no así los del Fo. Esto es importanete para el conocimiento de los pacientes en el preoperatorio

ABSTRACT

Con el objeto de evaluar las principales complicaciones tras la tiroidectomía total se realizó un estudio prospectivo histórico sobre 256 pacientes operados en nuestro servicio entre los años 1985 y 1997. La mayoría de ellos fueron intervenidos por enfermedades tiroideas benignas. Encontramos hipocalcemia permanente en el 1,5 por ciento de los casos y parálisis recurrenciales unilaterales definitivas en el 0,9 por ciento. Nuestro índice de mortalidad fue del 0,4 por ciento. Otras complicaciones evaluadas incluyeron: serohematoma, hemorragia postoperatoria, infección de la herida y embolismo pulmonar

ABSTRACT

Antecedentes: Las complicaciones postoperatorias son una de las objeciones más importantes a la tiroidectomía total en el carcinoma diferenciado de tiroides. Objetivo: Determinar el porcentaje y tipo de complicaciones postoperatorias de la tiroidectomía total en carcinoma diferenciado de tiroides, y relacionarlo con la bilateralidad y otras variables clínico-quirúrgicas. Lugar de aplicación: Servicio de Cirugía Oncológica de Cabeza y Cuello. Diseño: Observacional retrospectivo. Población: 136 pacientes consecutivos con tiroidectomía total, con o sin vaciamiento de cuello, por carcinoma diferenciado de tiroides. Método: Revisión de historias clínicas; el análisis estadístico se realizó con las pruebas de la T de Student y del chi cuadrado; seguimiento mínimo: 6 meses. Resultados: Se encontró carcinoma bilateral en 31 casos (28,8 por ciento); en 46 pacientes (33,8 por ciento) se registraron complicaciones: 42 hipocalcemias (31 transitorias y 11 definitivas), 4 hematomas y 2 neuropatías. Hubo hipocalcemia en 15 de 31 tumores bilaterales y en 27 de 105 unilaterales (p = 0,0011). No hubieron más complicaciones luego de las operaciones en dos tiempos (p = 0,1624). Conclusiones: La hipocalcemia es la complicación más frecuente de la tiroidectomía total, y se relaciona con enfermedad bilateral y vaciamiento asociado

ABSTRACT

Se presentan dos casos de cáncer intermedio de tiroides (CIT) operados en nuestro Servicio. Ambas pacientes presentaban un bocio y fueron intervenidas sin diagnóstico previo de esta patología. Se considera al CIT como un subtipo de cáncer medular con la capacidad de producir tanto tiroglobulina como calcitonina. Se analizan los casos y se revisa la literatura

ABSTRACT

El presente trabajo refiere la experiencia de 112 casos de cáncer tiroideo estudiados, tratados y evaluados en el Servicio de Cirugía de Cabeza y Cuello del Hospital Nacional Guillermo Almenara Irigoyen, durante un período de 20 años, desde 1965 hasta 1985. En este estudio se analizan las diferentes variedades del cáncer de la tiroides, demostrando la alta incidencia del cáncer bien diferenciado tiroideo, llegando a más del 80 por ciento. Con menor frecuencia se presentó el cáncer indiferenciado o anaplásico, y más raramente aún el cáncer medular. En la etapa inicial de la enfermedad, Estadío I, se presenta poco más del 21 por ciento. En el Estadío II se presentó el 37.5 por ciento de los casos; igual frecuencia en el Estadío III. En etapa diseminada de la enfermedad, Estadío IV se presentó el 3.57 por ciento. El tratamiento principalmente realizado fue la cirugía, desde la lobectomía total ampliada al itsmo, hasta una tiroidectomía sub-total y total. Para las metástasis cervicales se realizaron las disecciones radiales del cuello, de tipo estandar y con la cobaltoterapia, así mismo a las neoplasias que infiltraban la tráquea y los músculos pre-tiroideos. Es importante señalar que en el cáncer tiroideo en Estadío I bien diferenciado tanto papilar como folicular, la curación y sobrevida a 5, 10, 15 y más años, llegó al 100 por ciento, solamente con el tratamiento quirúrgico.
