Abstract: Background: During the detection ofneck recurrence in patients with Papillary Thyroid Carcinoma (PTC), sometimes it is difficult to distinguish metastatic from inflammatory neck lymph nodes. The measurement of serum thyroglobulin (sTg) under thyroid hormone suppression therapy the presence of serum thyroglobulin antibodies (sAbTg), the diagnostic whole body sean and cytology can give false negative results. Measurement of thyroglobulin in the washout fluid from fine-needle aspiration biopsy (FNAB) of suspicious neck lymph nodes could improve the diagnostic aecuracy Aim: To evaluate the usefulness of detecting Tg in lymph nodes (LTg) suspicious by ultrasonography (US) and compare it to cytology. Patients and Methods: Between the years 2004 and 2007 we prospectively studied 30 patients with PTC and cervical US findings of suspicious recurrence. LTg was assayed in US guided FNAB used for cytology. Results: Sixteen out of 30 patients underwent surgery using as selective criteria an LTg higher than sTg or a positive cytology. Surgery confirmed the presence of metástasis in all 15 patients with positive LTg (8 with positive cytology) and in 1 patient with negative LTg and positive cytology (a case with undifferentiated thyroid cancer). The sensitivity was 93.7% for LTg and 56.2% for cytology. We identified byLTg 3 of 6 patients with undetectable sTg and positive sAbTg. Conclusions: The presence of LTg showed a higher sensitivity than cytology for the detection of cervical lymph node metástasis. This method is useful even in the presence ofsAbTg.

Abstract: Introducción: El manejo de los ganglios cervicales es fundamental en el tratamiento y pronóstico de los pacientes con carcinoma escamoso de laringe. Existe consenso en realizar vaciamiento ganglionar cervical en ausencia de adenopatías clínicas (NO) cuando el riesgo de adenopatías metastásicas ocultas supera el 20%. El carcinoma laríngeo transglótico (CTG) se caracteriza por presentar una incidencia de metástasis cervicales ocultas de 30% a 40%. Objetivo: Evaluar los hallazgos histopatológicos en los ganglios cervicales de los pacientes portadores de CTG, analizando la incidencia de metástasis ocultas y su asociación con factores de riesgo. Material y métodos: Estudio retrospectivo mediante la revisión de las fichas clínicas de pacientes portadores de CTG, sin tratamiento previo, manejados quirúrgicamente en el Hospital San Juan de Dios entre los a os 1994 y 2002. Resultados: Se evaluaron 20 pacientes, 4 (20%) se presentaron con adenopatías clínicas, realizándose en 2 casos vaciamiento radical y en los 2 restantes disección funcional. Los pacientes NO fueron 16 y se les efectuó un vaciamiento funcional bilateral. Se detectaron metástasis ocultas en 12,5% de los pacientes NO. Conclusión: Los carcinomas de ubicación transglótica NO no se beneficiarían de un vaciamiento ganglionar cervical Introduction: The handling of the cervical ganglion is basic in the treatment and prognosis of patients with scaly carcinoma of the larynx. There is consensus on doing ganglionic cervical drainage in the absence of clinical adenopathies (NO) when the risk of hidden metastasic adenopathies is over 20%. Laryngeal transglotic carcinoma (LTC) is characterized for presenting an incidence of hidden cervical metastasis of 30 to 40%. Objective: To evaluate histopathological findings in the LTC patients' cervical ganglions, analyzing the incidence of hidden metastasis and their association with risk factors. Material and methods: Retrospective study through revision of the clinical files ofLTC carrier patients, without previous treatment, surgically treated at the San Juan de Dios Hospital between years 1994 and 2002. Results: 20 patients were evaluated, 4 (20%) presented clinical adenopathies, undergoing in 2 cases radical drainage and in the other 2, functional dissection. The NO patients were 16 and a bilateral functional drainage was made. Hidden metastasis were detected in 12,5% on the NO patients. Conclusion: Carcinomas of NO transglotic location did not benefit from a cervical ganglionic drainage

Abstract: El carcinoma escamoso es la principal neoplasia maligna de cabeza y cuello en los adultos. Esta neoplasia se origina en la mucosa del tracto aerodigestivo superior. Se discute su extensión en superficie y las metástasis a ganglios linfáticos cervicales. El compromiso ganglionar es el principal factor pronóstico independiente del carcinoma escamoso de cabeza y cuello, pues la presencia de adenopatías metastásicas reduce la sobrevida casi en 50%. La siguiente revisión se centra en tres temas relacionados con las metástasis ganglionares en carcinoma escamoso de cabeza y cuello (CECC): la clasificación de niveles ganglionares y de la disección ganglionar cervical, la técnica del ganglio centinela en el CECC y las técnicas de biología molecular para el diagnóstico del compromiso tumoral ganglionar Squamous cell carcinoma is the main head and neck malignant cancer in adults. This cancer originates from the upper aero digestive tract mucosa. Its surface extension and cervical lymph node metastases are discussed. Lymph node involvement is the main independent prognostic factor in head and neck squamous cell carcinoma, given that the presence of metastatic nodes reduce survival by approximately 50%. The present review focus on three topics related to lymph nodes metastasis of head and neck squamous cell carcinomas (CECC): Classification of lymph node levels and cervical node dissection, the sentinel lymph node technique in CECC, and the use of molecular biology techniques for diagnosing lymph node involvement
