Cuando el carcinoma de tiroides no es indolente: carcinoma de alto grado derivado del epitelio folicular / When Thyroid Carcinoma is not Indolent: High-Grade Carcinoma Derived From The Follicular Epithelium

Los carcinomas de tiroides derivados de células foliculares de alto grado (HGFDTC) son tumores poco frecuentes con un pronóstico intermedio entre carcinomas tiroideos bien diferenciados y anaplásicos. La clasificación de la OMS más reciente identifica dos tipos distintos de HGFDTC: 1) carcinoma de tiroides mal diferenciado (arquitectura sólida, trabecular o insular, falta de características nucleares de núcleos nucleares papilares y contorneados, necrosis mitosis (≥3/2mm2), y 2 ) Diferenciar carcinoma de tiroides de alto grado (recuento mitótico alto (≥5/mm2) y/o necrosis). Estos tumores son frecuentemente refractarios de radioyodo, tienen una alta propensión a metástasis distantes y una mala supervivencia general a largo plazo. Desde un punto de vista molecular, HGFDTC comparten mutaciones del controlador es decir, BRAF) y, con menos frecuencia, las fusiones genéticas (es decir, NTRK, RET) con arcinomas de tiroides diferenciados. A medida que ocurre la desdiferenciación, se adquieren alteraciones secundarias (como el promotor TERT y TP53). En esta revisión, nuestro objetivo es describir las características clínicas, moleculares y patológicas de HGFDTC, así como su gestión e investigación futura

High-grade follicular cell derived thyroid carcinomas (HGFDTC) are infrequent tumors with a prognosis intermediate between well differentiated and anaplastic thyroid carcinomas. The most recent WHO classification identifies two distinct types of HGFDTC: 1) Poorly differentiated thyroid carcinoma (solid, trabecular or insular architecture, lack of nuclear features of papillary nuclear and either convoluted nuclei, necrosis or mitosis (≥3/2mm2), and 2) differentiated high-grade thyroid carcinoma (high mitotic count (≥5/mm2) and/or necrosis). These tumors are frequently radioiodine refractory, have a high propensity for distant metastases, and poor long term overall survival. From a molecular standpoint, HGFDTC share driver mutations (ie BRAF) and, less frequently, gene fusions (ie NTRK, RET) with differentiated thyroid carcinomas. As dedifferentiation occurs, secondary alterations (such as TERT promoter, and TP53) are acquired. In this review, we aim to describe the clinical, molecular and pathological characteristics of HGFDTC, as well as their management and future research

Clinical Effect Observation of Apatinib Combined with 131I for Radioiodine-Refractory Differentiated Thyroid Cancer and Prognostic Significance Analysis of Macrophage Inflammatory Protein-1alpha After Treatment: A Cell Regulation Study / Observación del Efecto Clínico de Apatinib Combinado con 131I para el Cáncer de Tiroides Diferenciado Resistente al Yodo Radiactivo y Análisis de Importancia Pronóstica de la Proteína Inflamatoria 1alfa de Macrófagos Después del Tratamiento: Un Estudio de Regulación Celular

SUMMARY: The objective of this study was to observe the clinical efficacy of apatinib (AP) combined with 131I in the treatment of radioiodine-refractory differentiated thyroid cancer (RAIR-DTC) and the prognostic significance of MIP-1α after treatment, and to provide reference and guidance for future treatment and disease assessment of RAIR-DTC. One hundred and six patients with RAIR- DTC admitted to our hospital from January 2019 to October 2020 were selected for the study. All the patients were treated with TC surgery with 131I at our hospital, and 58 of them were subsequently transferred to AP treatment, which was considered as the research group; the other 48 patients were transferred to thyroid stimulating hormone (TSH) suppression treatment, which was considered as the control group. The clinical efficacy of the research group was better than that of the control group (P 0.05). After treatment, Tg, TL, maximum diameter of C/B lymph nodes, number of lymph nodes and number of calcified spots were lower in the research group than in the control group (P < 0.05). ROC analysis revealed that the predictive sensitivity of MIP-1α for prognosis of 3-year RAIR-DTC death in the research group of patients was 84.63 % and the specificity was 72.16 %. AP combined with 131I is effective in the treatment of RAIR-DTC and is worth using in the clinical practice. In addition, elevated levels of MIP-1α predicted a poor prognosis for patients with RAIR-DTC.

El objetivo de este estudio fue observar la eficacia clínica de apatinib (AP) combinado con 131I en el tratamiento del cáncer de tiroides diferenciado refractario al yodo radiactivo (RAIR-DTC) y la importancia pronóstica de MIP-1α después del tratamiento, y proporcionar referencia y orientación para futuros tratamientos y enfermedades. Evaluación de RAIR- DTC. Se seleccionaron para el estudio 106 pacientes con RAIR- DTC ingresados en nuestro hospital desde enero de 2019 hasta octubre de 2020. Todos los pacientes fueron tratados con cirugía CT con 131I, y 58 de ellos fueron trasladados posteriormente a tratamiento AP, los que fueron considerados como grupo de investigación; los otros 48 pacientes fueron transferidos a tratamiento de supresión de la hormona estimulante de la tiroides (TSH), que se consideró como grupo de control. La eficacia clínica del grupo de investigación fue mejor que la del grupo de control (P 0,05). Después del tratamiento, Tg, TL, diámetro máximo de los linfonodos C/B, número linfonodos y número de manchas calcificadas fueron menores en el grupo de investigación que en el grupo de control (P <0,05). El análisis ROC reveló que la sensibilidad predictiva de MIP-1α para el pronóstico de muerte por RAIR-DTC a 3 años en el grupo de pacientes de investigación fue del 84,63 % y la especificidad fue del 72,16 %. AP combinado con 131I es eficaz en el tratamiento del RAIR-DTC y vale la pena utilizarlo en la práctica clínica. Además, los niveles elevados de MIP-1α predijeron un mal pronóstico para los pacientes con RAIR- DTC.

Tiroidectomía total en enfermedad de graves basedow y tiroiditis. Complicaciones postoperatorias y relación con neoplasia tiroidea / Total thyroidectomy in graves basedow disease and thyroiditis. Postoperative complications and relationship with thyroid neoplasia

n. Los centros de alto volumen tienden a realizar tiroidectomías totales, tanto en patologías malignas y benignas. En este trabajo se analizan las complicaciones y la relación de las enfermedades estudiadas con la patología oncológica. Materiales y métodos. Se realizó una revisión de los pacientes intervenidos quirúrgicamente de Tiroidectomía Total (TT) por enfermedad de graves y tiroiditis. Se excluyeron las resecciones tiroideas parciales, subtotales, aquellas que requirieron linfadenectomía cervical y las realizadas por otras afecciones de la glándula entre enero 2010 y enero 2020 en el Servicio de Cirugía General N° 1, Hospital Nacional de Clínicas. Resultados. La histología fue del 64% para enfermedad de Graves, 28% Tiroiditis de Hashimoto y 8% Tiroiditis Linfocitaria (TL). El 100% de las TL presentaron Carcinoma Papilar de Tiroides (CPT) como resultado final de la anatomía patológica. El 25% del examen diferido de la pieza quirúrgica informó (CPT) en EG. Discusión. La complicación posoperatoria que rigió nuestra serie fue el Hipoparatiroidismo, manifestación que se presentó de manera transitoria en el 50% de la población estudiada, perdurando por más de seis meses en solo un caso (6%). Autores como Delbridge y cols. realizan el trasplante sistemático de al menos una paratiroides. La asociación de la neoplasia tiroidea fue elevada en nuestra serie, con una incidencia del 37%. Por lo que la Tiroidectomía debe ser total. Conclusión. La mayoría de los centros de cirugía endocrina del mundo, han difundido ampliamente el uso de la TT, por ser un procedimiento seguro en manos de cirujanos experimentados

n. High volume centers tend to perform total thyroidectomies, both in malignant and benign pathologies. This work analyzes complications and the relationship of diseases studied with oncological pathology. Materials and methods. A review of the patients surgically intervened with total thyroidectomy (TT) due to serious disease and thyroiditis was performed. Partial thyroid resections were excluded, subtotals, those that required cervical lymphadenectomy and those performed by other conditions of the gland between January 2010 and January 2020 in the General Surgery Service No. 1, National Hospital of Clinics. Results. Histology was 64% for serious disease, 28% hashimoto and 8% lymphocyte thyroiditis (TL). 100% of the FTAs presented papillary thyroid carcinoma (CPT) as a final result of the pathological anatomy. 25% of the deferred examination of the surgical piece reported (CPT) in EG. Discussion. The postoperative complication that governed our series was hypoparathyroidism, a demonstration that was presented temporarily in 50% of the population studied, enduring for more than six months in just one case (6%). Authors such as Delbridge et al. They perform the systematic transplant of at least one parathyroid. The Association of Thyroid Neoplasia was high in our series, with an incidence of 37%. So, the thyroidectomy must be total. Conclusion. Most of the world's endocrine surgery centers have widely disseminated the use of TT, for being a safe procedure in the hands of experienced surgeons

An executive summary of the Philippine Interim Clinical Practice Guidelines for the Diagnosis and Management of Well Differentiated Thyroid Cancer 2021

Objectives@#Thyroid cancer is the most common endocrine cancer in the Philippines affecting primarily women in the reproductive age group. Considering the burden of thyroid cancer in the country, the Department of Health (DOH) called for the development of a national clinical practice guideline that would address patient needs, and aid physicians in clinical decision-making while considering therapeutic cost and availability in the local setting. The 2021 guidelines are aimed at providing optimal care to Filipino patients by assisting clinicians in the evaluation of thyroid nodules and management of well differentiated thyroid cancer.@*Methods@#A steering committee convened to formulate clinical questions pertaining to the screening and evaluation of thyroid nodules, surgical and post operative management of thyroid cancer, and palliative care for unresectable disease. A technical working group reviewed existing clinical guidelines, retrieved through a systematic literature search, synthesized clinical evidence, and drafted recommendations based on the ADAPTE process of clinical practice guideline development. The consensus panel reviewed evidence summaries and voted on recommendations for the final statements of the clinical practice guidelines.@*Results@#The guidelines consist of clinical questions and recommendations grouped into six key areas of management of well differentiated thyroid cancer: screening, diagnosis, surgical treatment, post operative management, surveillance, and palliative care.@*Conclusion@#The 2021 guidelines for well differentiated cancer could direct physicians in clinical decision making, and create better outcomes for Filipino patients afflicted with the disease. However, patient management should still be governed by sound clinical judgement and open physician-patient communication.

Analysis of the incidence and mortality of thyroid cancer in Shandong Province from 2012 to 2022 based on the age-period-cohort model / 中华预防医学杂志

Objective: To analyze the trend of incidence and mortality of thyroid cancer and estimate its age-period-cohort effect in Shandong Province from 2012 to 2022. Methods: The Joinpoint regression was used to analyze the trend of incidence and mortality of thyroid cancer and calculate the average annual percentage change (AAPC) based on the data on thyroid cancer from 2012 to 2022. The age-period-cohort model was used to analyze the age-effect, time-effect and cohort-effect of thyroid cancer risk in the population aged over 20 years. Results: From 2012 to 2022, the incidence of thyroid cancer in Shandong province showed a significant upward trend, with an AAPC of 21.68% (95%CI: 19.14%-24.27%, P<0.001). The incidence of females was higher than that of males, and the incidence of urban areas was higher than that of rural areas. The trend of thyroid cancer mortality was relatively stable with an AAPC of -3.04% (95%CI:-8.81%-3.09%, P=0.323). The age effect of incidence increased with age before 60 years old and decreased with age after 60 years old. The incidence peaked in the age group of 55-59. The period effect increased with time. The cohort effect showed that the cohort born before 1957 had a downward trend over time, while the cohort born after 1957 had an upward trend. Conclusion: The incidence of thyroid cancer in Shandong shows a rising trend from 2012 to 2022. Age is an important factor affecting the risk of thyroid cancer. The mortality of thyroid cancer remains stable.

Clinical manifestations of I-131 induced salivary gland dysfunction in patients with thyroid carcinoma

Aim: To carry out a retrospective analysis of the frequency and severity of clinical signs of radioiodine (131I)-induced damage to the salivary glands in the early and long-term post-radiation periods, and identify risk factors for their occurrence in patients with differentiated thyroid carcinomas. Methods: A total of 330 patients underwent thyroidectomy with dissection of lymphatic nodes. One month after surgery, all the patients received radioiodine therapy. The dose and number of courses varied depending on the stage and morphological type of the tumor. In the late post-radiation period, the patients were surveyed with the use of a standard questionnaire, which allowed retrospective assessment of the nature and severity of symptoms of radiationinduced damage, as well as the time of their onset/subsidence. Results: Radiation-induced sialoadenitis of the salivary glands was observed in 51.2% of patients treated with 131I. The main symptoms included pain and discomfort in the salivary glands (51.2% of patients), swelling (48.8%), transient or permanent dry mouth (38%), and distortion of taste (38%). There were statistically significant correlations between the presence and severity of the main clinical symptoms of salivary gland irradiation. A significant relationship (r = 0.91, p < 0.001) was found between swelling of the salivary glands and the feeling of pain or discomfort, which was indicative of inflammation and retention of saliva. Conclusion: The main factors influencing the formation of chronic radiation-induced sialoadenitis and the severity of the inflammatory process included the tumor stage, the total dose of radiopharmaceuticals, and the duration following radioiodine therapy

Adaptation and validation of the Spanish version of the thyroid-cancer-specific Thyca-QoL scale: A cross-sectional study / Adaptación y validación de la versión en español de la escala thyroid-cancer-specific Thyca-QoL: Estudio de corte transversal

Introduction. Thyca-QoL is a specific instrument to assess QoL in thyroid cancer patients, but it is not validated in Spanish language. The aim was to assess the psychometric properties of the Thyca-QoL. Methods. This is a prospective cross-sectional study. The Thyca-QoL was translated and adapted to Spanish language. A psychometric validation using an exploratory principal axis factor analysis and confirmatory analysis, concurrent validation compared with EORTC QLQ-C30 and a test-retest reliability assessment was done. Results. A total of 296 patients were included. Exploratory factor analysis showed a seven-factor solution with good diagnostic tests results. Cronbach ́s alpha for the global scale was 0.86. The comparison between the Thyca-QoL and the EORTC QLQ-C30 demonstrated a high correlation (rho= 0.75) and coefficient for test-retest was 0.87. Discussion. The validation process followed all the methodological steps necessary to guarantee the performance of the instrument. The measurements of the internal validity, reliability, and reproducibility reached similar results as the original validation. The factor analysis showed a solution with seven factors that resembles the original results. Reproducibility was high for voice, sympathetic, sex, and chilliness domains and moderate for the others; the instrument had the ability to discriminate between clinical conditions. Conclusion. The spanish version of the thyroid-cancer-specific Thyca-QoL is a reliable and objective instrument to be used in clinical practice and for research objectives in Spanish speaking patients

Factores de riesgo asociados a la malignidad de nódulos tiroideos en mujeres adultas: Estudio observacional de centro único / Risk factors associated with malignancy of thyroid nodules in adult womens: A single-center observational study

Introducción: Aunque la mayoría de los nódulos tiroideos son benignos, asintomáticos y estables en la historia clínica de una paciente mujer; en los estudios ecográficos, citológicos e histopatológicos se ha podido obtener la caracterización subclínica de lesiones sugestivas de malignidad. El actual estudio tuvo por objetivo evaluar los factores de riesgo asociados a la malignidad de nódulos tiroideos en pacientes adultas. Metodología: Se realizó un estudio descriptivo, transversal, retrospectivo correlacional de enfoque mixto en el servicio de endocrinología del Hospital Teodoro Maldonado Carbo entre Enero y Junio del 2019. El universo estuvo compuesto por todos los casos con diagnóstico de nódulo tiroideo. Se utilizó el sistema de Bethesda para los reportes. Resultados: Fueron 132 casos de pacientes con nódulos tiroideos, edad entre 45 a 64 años (57,6%). En estado pre menopáusico (52%), con 1 gestación (12%), glucosa >100 mg/dL (34%), IMC entre 25.0 y 29.9 kg/m2 (49%) y con antecedente patológico familiar de cáncer de tiroides (35%). 30 casos con valores de TSH >4.00 uUI/mL (23%). El sistema de Bethesda, 22 casos (17%) categoria IV, 17 casos (13%) categoria V y 11 casos (8%) categoría VI. Conclusiones: La lesión citológica tiroidea más frecuente que se encontró fue la neoplasia benigna. No obstante, la lesión maligna junto con la lesión folicular indeterminada presentaron una prevalencia del 8%. Se encontró una asociación significativa entre los nódulos de citología maligna con los niveles de TSH elevados y con el antecedente patológico familiar de cáncer de tiroides.

Introduction: Although most thyroid nodules are benign, asymptomatic, and stable in the clinical history of a female patient, in ultrasound, cytological, and histopathological studies, it has been possible to obtain the subclinical characterization of lesions suggestive of malignancy. The current study aimed to evaluate the risk factors associated with the malignancy of thyroid nodules in adult patients. Methodology: A descriptive, cross-sectional, retrospective, correlational study with a mixed approach was carried out in the endocrinology service of the Teodoro Maldonado Carbo Hospital between January and June 2019. The study population consisted of all patients diagnosed with thyroid nodules. The Bethesda system was used for reporting. Results: There were 132 patients with thyroid nodules aged between 45 and 64 (57.6%). In a premenopausal state (52%), there was one pregnancy (12%), glucose >100 mg/dL (34%), BMI between 25.0 and 29.9 kg/m2 (49%) and a family history of thyroid cancer (35%). Thirty patients had TSH values >4.00 µUI/mL (23%). In the Bethesda system, 22 cases (17%) were Category IV, 17 cases (13%) were Category V, and 11 cases (8%) were Category VI. Conclusions: The most frequent thyroid cytological lesion found was a benign neoplasm. However, malignant lesions and indeterminate follicular lesions presented a prevalence of 8%. A significant association was found between malignant cytology nodules with elevated TSH levels and a family history of thyroid cancer.

Cuidados paliativos prolongados, a propósito de un caso / Prolonged paliative care: case report

Actualmente, las recomendaciones sobre cuidados paliativos sugieren que éstos se inicien lo más tempranamente posible, con el objetivo de mejorar la calidad de vida del paciente y su familia, con un enfoque biopsicosocial. A pesar de ello, aún persiste en gran parte del personal de salud la idea de que los cuidados paliativos son estrictamente cuidados de fin de vida, por lo que se asocia inconscientemente un paciente en una fase final de su enfermedad. Algunos estudios sugieren que, a pesar de las recomendaciones, la práctica habitual aún mantiene esta costumbre. Adicionalmente, no existe una duración establecida para definir cuánto deberían durar estos cuidados. A continuación, el reporte de un caso de cáncer de tiroides papilar, neoplasia conocida por su curso relativamente benigno, para tratarse de un cáncer, de lenta progresión. Este fue diagnosticado de forma tardía, con metástasis pulmonar e insuficiencia respiratoria como primer motivo de consulta, hace 8 años. Esto contrasta enormemente con la duración promedio de cuidados paliativos alrededor del mundo, que se estima es de 19 días. El reporte de este caso pretende contrastar estas realidades y mostrar un ejemplo de cuidados paliativos prolongados, los beneficios y también posibles consecuencias que éstos han tenido en la vida del paciente.

Currently, recommendations about palliative care suggest that they should be started as early in the course of the disease as possible, with the goal of improving quality of life for patients and their families, with a biopsychosocial approach. Despite this, there's still a pervasive idea among healthcare givers that palliative care is given exclusively at the end of life, thus there's a subconscious association with a patient in the final stages of their disease. Studies suggest that despite recommendations, actual practice maintains this custom. Additionally, there's no definitive duration for palliative care. The following is a case report of papillary thyroid cancer, a disease known for a relatively benign course compared to other forms of cancer, and slow progression. This disease was diagnosed in an advanced stage, with pulmonary metastasis and respiratory failure, 8 years ago. This is in stark contrast with the average duration of palliative care around the world, which is estimated to be 19 days. This report intends to highlight this difference and show an example of prolonged palliative care, the benefits and potential consequences that these may have had on the patient's life.

Beyond the Recommendations of the Clinical Guidelines for Medullary Thyroid Cancer - A Case Report / Más allá de las recomendaciones de las guías clínicas de cáncer medular de tiroides - a propósito de un caso

Medullary thyroid cancer (MTC) is a rare disease from parafollicular C cells. Calcitonin has been suggested as a screening; its levels are proportional to the tumor size and predictive of metastatic disease. We present a case where an early action was taken with lower cut-off points. Male patient, 49 years old. Thyroid ultrasound (US) with a suspicious nodule. Fine Needle Aspiration Biopsy (FNAB) suggests MTC, with pre-operative serum calcitonin (CTN) of 591 pg/mL. Total thyroidectomy with central and bilateral dissection was performed. Biopsy: MTC in left nodule of 26 mm without lymph nodes (LN) metastases. Follow-up with undetectable CTN for six years. After that, CT was 4.7 pg/mL, and carcinoembryonic antigen (CEA) was 1.2 ng/mL. Neck US showed bilateral LN. FNAB of LN does not show recurrence. A progressive rise of markers with doubling time of CTN and CEA was 16 and 51.3 months, respectively. CTN raised until 112 pg/mL. Given the lack of cervical compromise, a neck and lung CT, liver MRI, and bone scintigraphy were ordered despite CTN levels < 150 pg/mL. MRI showed hypervascular hepatic lesions, contrasted with gadoxetic acid. PET Ga68-DOTATATE showed lesions with overexpression of somatostatin receptors in the liver. Surgery was done, and a biopsy confirmed metastases. Conclusions: The clinical guidelines may allow the management of cases; however, they should be used considering each case context. In our patient, if the guidelines had been strictly followed, it would not have been possible to detect liver metastases to achieve a surgical resection with curative intent.

Paciente masculino, 49 años. Ecografía tiroidea con nódulo sospechoso. Biopsia por aspiración con aguja fina (PAAF) sugiere cáncer medular de tiroides (CMT), calcitonina sérica preoperatoria (CTN) de 591 pg/mL. Se realizó tiroidectomía total con disección central y bilateral. Biopsia: CMT en nódulo tiroideo izquierdo de 2,6 cm sin metástasis en 29 ganglios linfáticos (GL). En el seguimiento, CTN sérica indetectable durante 6 años. Posteriormente CTN sérica de 4,7 pg/mL y antígeno carcinoembrionario (CEA) de 1,2 ng/mL. Ecografía cervical de control mostró GL subcentimétricos bilaterales en grupo IV. PAAF de GL sin evidencia de malignidad, con niveles de CTN indetectables en la muestra. El doblaje de CTN y CEA fue 16 y 51,3 meses respectivamente. Dado ausencia de compromiso cervical, se solicitó TC de cuello y tórax, RM hepática y gammagrafía ósea, a pesar de no presentar niveles de CTN > 150 pg/mL. La RM mostró 3 lesiones hepáticas hipervasculares; se complementa con un PET Ga-DOTATATE que mostró 2 lesiones focales con sobreexposición de receptores de somatostatina en el parénquima hepático, con SUVmáx de 6,8 y 7,3. Se realiza cirugía extirpando 5 lesiones; la biopsia confirmó metástasis de CMT. Conclusiones: Las guías clínicas pueden dar orientaciones generales y permitir el manejo de casos basados en la evidencia; sin embargo, siempre deben usarse considerando el contexto de cada caso en particular. Si se hubieran seguido estrictamente las pautas, no habría sido posible detectar las metástasis hepáticas dentro de la ventana de oportunidad para lograr una resección quirúrgica con intención curativa.

Experiencia en cirugía de tiroides en el Hospital Oncológico Conrado Benítez de Santiago de Cuba / Thyroid Surgery Experience at Hospital Oncológico Conrado Benítez of Santiago de Cuba

Introducción: Los nódulos de tiroides son un problema clínico común. La tiroidectomía es una de las técnicas más realizadas en los servicios de cabeza y cuello y constituye un tratamiento con intención curativa en el cáncer de tiroides y afecciones benignas como el bocio nodular y el adenoma. Objetivo: Describir la experiencia en cirugía de tiroides del servicio de cabeza y cuello en el Hospital Oncológico Conrado Benítez. Métodos: Se realizó un estudio descriptivo, longitudinal y prospectivo de los pacientes que recibieron algún tratamiento quirúrgico por enfermedad tiroidea en el período comprendido entre el 1 de septiembre de 2017 y el 31 de agosto de 2022. Resultados: El 87 por ciento de los pacientes eran mujeres, con una edad media de 47,1 años. A todos se les realizó ecografía y biopsia por aspiración con aguja fina con una estrecha concordancia con el diagnóstico definitivo. Predominó el carcinoma papilar (39,5 por ciento), la tiroidectomía total como técnica más empleada (86,5 por ciento) y el 94,6 por ciento de los pacientes no tuvo complicaciones. La lesión recurrencial solo estuvo presente en el 1,1 por ciento de los casos. Conclusiones: La experiencia en tiroidectomía en el Hospital Oncológico Conrado Benítez es buena, con una concordancia entre medios diagnósticos y biopsia definitiva, tiempo quirúrgico adecuado y pocas complicaciones(AU)

Introduction: Thyroid nodules are a common clinical problem. Thyroidectomy is one of the most performed techniques in head and neck surgery services, as well a treatment with curative intent for thyroid cancer and benign conditions such as nodular goiter and adenoma. Objective: To describe the experience in thyroid surgery at the head and neck surgery service from Hospital Oncológico Conrado Benítez. Methods: A descriptive, longitudinal and prospective study was carried out with patients who received any surgical treatment for thyroid disease in the period from September 1, 2017 to August 31, 2022. Results: 87 percent of patients were female, with a mean age of 47.1 years. All of them underwent ultrasonography and fine-needle aspiration biopsy, presenting a close concordance with their definitive diagnosis. Papillary carcinoma predominated (39.5 percent), total thyroidectomy was the most commonly used technique (86.5 percent) and 94.6 percent of patients had no complications. Any recurrent lesion was present in only 1.1 percent of cases. Conclusions: The thyroidectomy experience at Hospital Oncológico Conrado Benítez is good, based on the concordance between diagnostic means and definitive biopsy, as well as adequate surgical time and few complications(AU)

Oncocitoma quístico papilar de carúncula lagrimal / Papillary Cystic Oncocytoma of Lacrimal Caruncle

La carúncula lagrimal forma parte de los anexos oculares y es asiento ocasional de neoplasias, las cuales en su mayoría son benignas. Dentro de estos tumores se encuentran los oncocitomas, los cuales están constituidos por células oncocíticas (oxifílicas) y poseen una baja incidencia con menos del 3 por ciento de los tumores y bajos reportes de casos en la literatura. A pesar de que existen varios estudios en Cuba de tumores de anexos oculares no hay evidencia actualizada de casos con oncocitoma. Por ello se considera necesaria la presentación de este caso. Se trata de paciente blanca, femenina de 83 años de edad con antecedentes de hipertensión arterial, compensada bajo tratamiento y de carcinoma basocelular, operada hace siete años. Acudió por presentar aumento de volumen indoloro en el ángulo interno del ojo izquierdo. Al examen físico oftalmológico se observó lesión de 1 cm, gris-rosácea, bien delimitada. Se procedió a su exéresis con sospecha clínica de carcinoma basocelular y se envió espécimen para estudio anatomopatológico, el cual concluyó como oncocitoma quístico papilar (cistoadenoma papilar eosinofílico) de carúncula(AU)

The lacrimal caruncle is part of the ocular adnexa and is the occasional seat of neoplasms, most of which are benign. Among these tumors are oncocytomas, which are constituted by oncocytic (oxyphilic) cells and have a low incidence with less than 3 percent of tumors and low case reports in the literature. Although there are several studies in Cuba of ocular adnexal tumors, there is no updated evidence of cases with oncocytoma. Therefore, it is considered necessary to present this case. The patient is a white, 83-year-old female with a history of arterial hypertension, compensated under treatment and basal cell carcinoma, operated seven years ago. She presented with painless enlargement of the inner corner of the left eye. Ophthalmologic physical examination revealed a 1 cm lesion, grayish-pinkish, well demarcated. The lesion was excised with clinical suspicion of basal cell carcinoma and the specimen was sent for anatomopathologic study, which concluded as papillary cystic oncocytoma (eosinophilic papillary cystoadenoma) of the caruncle(AU)

Riesgo de recurrencia dinámico en pacientes con microcarcinoma de tiroides con y sin ablación con Yodo-131 / Dynamic risk of recurrence in patients with thyroid microcarcinoma with and without iodine-131 ablation

Introducción: El cáncer diferenciado de tiroides ha incrementado su incidencia en las últimas 3 décadas debido al sobrediagnóstico de tumores pequeños o microcarcinomas, las nuevas tendencias en su manejo hacen de la cirugía y la terapia con iodo radioactivo el tratamiento de elección para casos seleccionados. El manejo actual de microcarcinoma de tiroides se basa en el riesgo de recurrencia inicial y su seguimiento en el tiempo con el riesgo de recurrencia dinámico. Objetivo: El presente trabajo se enfocó en analizar el riesgo de recurrencia dinámico en pacientes con microcarcinoma de tiroides que recibieron o no terapia ablativa con Iodo 131 posterior a tratamiento quirúrgico en el Hospital Teodoro Maldonado Carbo durante los años 2016 ­ 2018. Métodos: Se realizó un estudio ambispectivo, no experimental, descriptivo, analítico, transversal y correlacional. Se analizaron 51 pacientes atendidos en la unidad técnica de endocrinología. Resultados: De un total de 51 casos de microcarcinoma, el 60% fue tratado con terapia ablativa, la respuesta inicial fue excelente en el 53.3% de pacientes ablacionados y en el 66.7% de los casos no ablacionados. El riesgo de recurrencia inicial fue significativamente más bajo en el grupo no tratado mediante ablación (100%), mientras que en el tratado con ablación fue bajo, intermedio y alto en 16 (53.3%), 7 (23.3) y 7 (23.3), respectivamente. Conclusiones: Existe un riesgo bajo de recurrencia dinámico, independientemente de la indicación de terapia ablativa con I131, la estratificación del riesgo de recurrencia constituye una herramienta útil para seleccionar aquellos pacientes que deben recibir iodo radioactivo.

Introduction: Differentiated thyroid cancer has increased its incidence in the last 3 decades due to overdiagnosis of small tumors or microcarcinomas; new trends in its management make surgery and radioactive iodine therapy the treatment of choice for selected cases. The current management of thyroid microcarcinoma is based on the initial risk of recurrence and its follow-up over time with the dynamic risk of recurrence. Objective: The present work focused on analyzing the risk of dynamic recurrence in patients with thyroid microcarcinoma who received or did not receive ablative therapy with Iodine 131 after surgical treatment at the Teodoro Maldonado Carbo Hospital during the years 2016 - 2018. Methods: An ambispective, non-experimental, descriptive, analytical, cross-sectional, and correlational study was carried out. Fifty-one patients treated at the endocrinology technical unit were analyzed. Results: Of 51 cases of microcarcinoma, 60% were treated with ablative therapy, and the initial response was excellent in 53.3% of ablated patients and 66.7% of non-ablated cases. The initial recurrence risk was significantly lower in the group not treated by ablation (100%). In contrast, in the group treated with ablation, it was low, intermediate, and high in 16 (53.3%), 7 (23.3), and 7 (23.3), respectively. Conclusions: There is a low risk of dynamic recurrence, regardless of the indication for ablative therapy with I131; a recurrence risk stratification is a helpful tool for selecting those patients who should receive radioactive iodine.

Clinicopathological analysis of superior mediastinal lymph node metastases in medullary thyroid carcinoma / 中华肿瘤杂志

Objective: To investigate the clinicopathological characteristics of superior mediastinal lymph node metastases (sMLNM) in medullary thyroid carcinoma (MTC). Methods: This retrospective analysis enrolled the patients who were treated for sMLNM of MTC in our hospital from May 2012 to January 2021. All patients were suspected of sMLNM due to preoperative imaging. According to the pathological results, the patients were divided into two groups named sMLNM group and the negative superior-mediastinal-lymph-node group. We collected and analyzed the clinical features, pathological features, pre- and post-operative calcitonin (Ctn), and carcinoembryonic antigen (CEA) levels of the two groups. Logistic regression analysis was used to analyze risk factors, and receiver operation characteristic (ROC) curves were drawn to determine the optimal cut-off values of preoperative Ctn and preoperative CEA for predicting sMLNM. Results: Among the 94 patients, 69 cases were in the sMLNM group and 25 cases were in the non-SMLNM group. Preoperative Ctn level (P=0.003), preoperative CEA level (P=0.010), distant metastasis (P=0.022), extracapsular lymph node invasion (P=0.013), the number of central lymph node metastases (P=0.002) were related to sMLNM, but the multivariate analysis did not find any independent risk factors. The optimal threshold for predicting sMLNM by pre-operative Ctn is 1500 pg/ml and AUC is 0.759 (95% CI: 0.646, 0.872). The sensitivity, specificity, positive predictive value, and negative predictive value of diagnosis are 61.2%, 77.3%, 89.1%, 39.5%, respectively. In patients who underwent mediastinal lymph node dissection through transsternal approach, the metastatic possibility of different levels from high to low were level 2R (82.3%, 28/34), level 2L (58.8%, 20/34), level 4R (58.8%, 20/34), level 3 (23.5%, 8/34), level 4L (11.8%, 4/34). Postoperative complications occurred in 41 cases (43.6%), and there was no perioperative death in all cases. 14.8% (12/81) of the patients achieved biochemical complete response (Ctn≤12 pg/ml) one month after surgery, 5 of these patients were in sMLNM group. Conclusions: For patients who have highly suspicious sMLNM through imaging, combining with preoperative Ctn diagnosis can improve the accuracy of diagnosis, especially for patients with preoperative Ctn over 1 500 pg/ml. The superior mediastinal lymph node dissection for the primary sternotomy should include at least the superior mediastinal levels 2-4 to avoid residual lesions. The strategy of surgery needs to be cautiously performed. Although the probability of biochemical cure in sMLNM cases is low, nearly 40% of patients can still benefit from the operation at the biochemical level.

A retrospective comparative study between robotic thyroidectomy through transoral vestibular approach and bilateral breast-axillary approach / 中华外科杂志

Objective: To compare the surgical outcome of robotic thyroidectomy through transoral approach and the bilateral breast-axillary approach. Methods: Retrospective analysis was made on the clinical data of patients who performed transoral robotic thyroidectomy (TORT group) or bilateral breast-axillary approach (BABA group) in the Department of Thyroid and Breast Surgery, the 960th Hospital of People's Liberation Army from July 2020 to May 2022. Both groups received lobectomy with lymph node dissection of the central region. A total of 100 cases were included in the study, including 48 cases in the TORT group and 52 cases in the BABA group. The propensity score matching method was used for 1∶1 matching of patients between the 2 groups, with a match tolerance of 0.03. There were 31 patients in each group successfully matched. In the TORT group, there were 5 males and 26 females, aged (33.2±7.9) years (range: 21 to 53 years). While there were 4 males and 27 females in the BABA group, aged (34.6±9.2) years (range: 19 to 58 years). The t test, Mann-Whitney U test, χ2 test or Fisher exact test were used to compare the clinical efficacy between the two groups. Results: All the patients successfully completed robotic thyroid surgery without conversion to open surgery. Compared with BABA group, the TORT group had longer operation time ((211.3±57.2) minutes vs. (126.2±37.8) minutes, t=6.915, P<0.01), shorter drainage tube retention time ((5.4±1.0) days vs. (6.4±1.2) days, t=-3.544, P=0.001), shorter total hospital stay ((6.6±1.2) days vs. (7.4±1.3) days, t=-2.353, P=0.022), and higher cosmetic score (9.46±0.25 vs. 9.27±0.26, t=2.925, P=0.005). There was no significant difference between the two groups in the number of lymph nodes dissection, metastasis in the central compartment, and the incidence of postoperative complications (all P>0.05). Conclusions: Compared with the bilateral breast-axillary approach, the transoral vestibular approach of robotic thyroidectomy is also safe and effective. It shows similar surgical results to the bilateral breast-axillary approach in strictly selected patients, but the postoperative recovery speed is much faster, and the hospital stay is shorter. Transoral robotic thyroidectomy is a more recommended surgical method for patients with high aesthetic demand.

Clinical characteristics and prognosis of anaplastic thyroid carcinoma: a 20-year single-center retrospective study / 中华耳鼻咽喉头颈外科杂志

Objectives: To investigate the clinical characteristics and prognoses of patients with anaplastic thyroid carcinoma(ATC), and to explore the value of multi-modality treatment in improving overall survival(OS) of ATC patients. Methods: Medical records including clinicopathological data of patients diagnosed with ATC at Cancer Hospital, Chinese Academy of Medical Sciences between 2001 and 2020 were retrospectively analyzed. The cohort were divided into surgery-only and multi-modality subgroups, and the latter included patients treated with surgery plus radiotherapy and/or medical therapy(including chemotherapy, target therapy and immunotherapy). Univariate survival analysis was conducted through Kaplan-Meier method, and multivariate survival analysis was performed using Cox proportional hazard model. Results: A total of 47 patients were included in the study, including 24 males and 23 females, with a median age of 63 years. After a median follow-up duration of 3.37 months, 42 patients died due to tumor recurrence or progression. The median OS of the cohort was 4.33 months. Univariate survival analysis demonstrated that symptoms of recurrent laryngeal nerve(RLN) involvement, distant metastasis, leukocyte elevation, and treatment modality were significantly associated with OS (P values all<0.05). Multivariate analysis showed that symptoms of RLN involvement(HR=2.49, 95%CI: 1.16-5.32, P=0.019), distant metastasis(HR=2.33, 95%CI: 1.06-5.16, P=0.036), and leukocyte elevation(HR=2.50, 95%CI: 1.16-5.40, P=0.020) were all independent risk factors for OS, while multi-modality therapy significantly prolonged OS compared with surgery alone(HR=0.22, 95%CI: 0.10-0.47, P<0.001). Conclusions: Among ATC patients, absence of symptoms of RLN invasion, normal leukocyte level and absence of distant metastasis at initial diagnosis are all independent protective factors for OS and multi-modality treatment can help to improve the prognosis.

Contrast-enhanced ultrasonography with intra-glandular contrast injection can improve the diagnostic accuracy of central compartment lymph node metastasis of thyroid cancer / 南方医科大学学报

OBJECTIVE@#To investigate the value of lymphatic contrast-enhanced ultrasound (LCEUS) with intra-glandular injection of contrast agent for diagnosis of central compartment lymph node metastasis of thyroid cancer.@*METHODS@#From November, 2020 to May, 2022, the patients suspected of having thyroid cancer and scheduled for biopsy at our center received both conventional ultrasound and LCEUS examinations of the central compartment lymph nodes before surgery. All the patients underwent surgical dissection of the lymph nodes. The perfusion features in LCEUS were classified as homogeneous enhancement, heterogeneous enhancement, regular/irregular ring, and non-enhancement. With pathological results as the gold standard, we compared the diagnostic ability of conventional ultrasound and LCEUS for identifying metastasis in the central compartment lymph nodes.@*RESULTS@#Forty-nine patients with 60 lymph nodes were included in the final analysis. Pathological examination reported metastasis in 34 of the lymph nodes, and 26 were benign lymph nodes. With ultrasound findings of heterogeneous enhancement, irregular ring and non-enhancement as the criteria for malignant lesions, LCEUS had a diagnostic sensitivity, specificity and accuracy of 97.06%, 92.31% and 95% for diagnosing metastatic lymph nodes, respectively, demonstrating its better performance than conventional ultrasound (P < 0.001). Receiver-operating characteristic curve analysis showed that LCEUS had a significantly greater area under the curve than conventional ultrasound for diagnosing metastatic lymph nodes (94.7% [0.856-0.988] vs 78.2% [0.656-0.878], P=0.003).@*CONCLUSION@#LCEUS can enhance the display and improve the diagnostic accuracy of the central compartment lymph nodes to provide important clinical evidence for making clinical decisions on treatment of thyroid cancer.
