Objetivo: revisar e informar la experiencia adquirida con el manejo de tumores de células germinales del mediastino, en el Hospital Calderón Guardia. Metodología: previa autorización del Comité de Ética del Hospital, se realizó un análisis descriptivo de la información acumulada en la base de datos del Servicio de Cirugía de Tórax y los expedientes clínicos de 29 pacientes con tumores de células germinales del mediastino, operados entre 1986 y 2012. Resultados: se encontró mayor frecuencia en hombres jóvenes con una relación por género de 13.5:1, y edad promedio de 26 años. La localización correspondió en 28 casos al mediastino antero superior y 1 al medio. La presentación en 27 casos fue una radiografía de tórax con ensanchamiento del mediastino, uno con derrame pleural y uno con derrame pleural y mediastino ensanchado. Los síntomas más frecuentes fueron: disnea, dolor retroesternal, fiebre, tos, pérdida de peso, síndrome de vena cava superior, hemoptisis y ginecomastia en un varón con coriocarcinoma. La muestra para diagnóstico se obtuvo por mediastinotomía en 14 casos, toracotomía en 8, videotoracoscopia en 4, esternotomía en 1, mediastinoscopia en 1 y broncoscopia en 1. Conclusión: los tumores germinales del mediastino son infrecuentes; la extirpación quirúrgica es el tratamiento de elección para los técnicamente resecables y se acompaña de curación de los benignos. En los malignos, la aparente resección completa no es garantía de curación, por lo que debe considerarse la quimioterapia adyuvante, que demostró ser de gran utilidad, por cuanto varios tumores parcialmente resecados se curaron con quimioterapia, y algunos con aparente resección completa recidivaron. los tumores germinales del mediastino son infrecuentes; la extirpación quirúrgica es el tratamiento de elección para los técnicamente resecables y se acompaña de curación de los benignos.

Background: To review and inform about the experience acquired with management of germ cell tumors of the mediastinum at the Calderón Guardia Hospital. Methods: Twenty-nine patients with mediastinal germ cell tumors were operated between 1986 and 2012 in the Thoracic Surgery Department. General information was obtained from the department´s database and these patients’ clinical files were reviewed with authorization from the Hospital’s Ethics Committee. Results: Subjects were predominantly young males with a gender ratio of 13.5:1 and a mean age of 26. Masses were located in the anterior mediastinum in 28 cases and in the middle mediastinum in 1 case. Twenty-seven cases were suspected due tomediastinal widening on chest x-ray examination, 1 to pleural effusion and 1 to pleural effusion and mediastinal widening. The most frequently found symptoms were dyspnea, retrosternal chest pain, fever, cough, weight loss, superior vena cava syndrome, hemoptysis and gynecomastia in one male with coriocarcinoma. Tissue for diagnosis was obtained in 14 cases by mediastinotomy, in 8 by thoracotomy, in 4 by video assisted thoracoscopy, in 1 by sternotomy, in 1 by mediastinoscopy and in 1 by bronchoscopy. Conclusion: Germ cell tumors of the mediastinum are infrequent, with higher prevalence in young males. Complete surgical excision remains the treatment of choice for resectable tumors, which are usually of more benign histology. Cure is not guaranteed by apparent total resection of malignant germ cell tumors, therefore primary or adjuvant chemotherapy should always be considered given that it was curative for some partially resected tumors and others with apparent total resection recidivated.

¹la teoría señala que algunas de estas células pueden quedar en el mediastino y dar origen a tumores de células germinales. Otra teoría se refiere a que se trata de células metastásicas de tumores originados en las gónadas, sin embargo, es raro encontrar la asociación de tumores germinales del mediastino y en las gónadas.²

La estirpe histológica se relaciona muchas veces con el tratamiento. Los teratomas, en la mayoría de casos, son usualmente quirúrgicos en un primer tiempo, mientras que el resto de tumores, aunque tienden a presentarse con un patrón invasivo, tienen buen pronóstico con el uso de quimioterapia.⁷En algunos casos es necesaria la resección quirúrgica de restos tumorales, siendo de buen pronóstico el hallar un tumor necrosado.⁸^,9^{Cuadro 1}

Metodos

¹⁰El Servicio de Cirugía de Tórax del HCG, es un centro de alta referencia, y en un periodo de 26 años se operó solo a 29 pacientes, a razón de 1,1 por año. Algunos tumores se diagnosticaron y trataron de manera exclusiva con los marcadores tumorales, por lo que la frecuencia es mayor a la de los operados.¹¹En un estudio de Navarro y colaboradores, en hospitales metropolitanos de Costa Rica en 1996, el tumor de células germinales resultó ser el más frecuente de los tumores del mediastino.¹²

¹³La detección se hace al observar un ensanchamiento anormal del mediastino y la TAC ofrece información valiosa en cuanto a las características particulares de la tumoración, sobre todo para planificar la vía para tomar la biopsia o el abordaje quirúrgico.¹⁴

¹so the theory is that some of these cells may be left in the mediastinum and they give rise to germ cell tumors. Another theory says that they are metastatic tumor cells that originated in the gonads, however, it is rare to find the association of mediastinal germ cell tumors with gonadal tumors.²

⁷In some cases, surgical resection of the residual tumor is necessary, being of a good prognosis the finding of necrotizing tissue.^8,9

The presentation, in 27 cases, was with widened of the mediastinum at the chest X-rat, one with a pleural effusion and one with pleural effusion and widened of the mediastinum. Only in 24 cases adequate clinical information was found about symptoms in the clinical record; 4 patients were asymptomatic, 20 were symptomatic and the most common symptoms were: 16 cases with dyspnea, 12 cases with retrosternal pain or discomfort, 11 cases had fever, 9 cases had cough, 8 cases had weight loss, 8 cases had superior vena cava syndrome, 1 case had hemoptysis and 1 case had male gynecomastia in a patient with choriocarcinoma.

Table 1, where the highest frequency was mixed tumors, then followed by teratomas and seminomas, and it is less frequent to find coriocacinomas and yolk sac tumors.

¹⁰The Thoracic Surgery Department of HCG, is a reference center, and in a period of 26 years only 29 patients were operated with a rate of 1.1 case per year. Some tumors were diagnosed and treated using exclusively serological markers, so the frequency is higher than the one reported.¹¹In a study by Navarro et al, in metropolitan hospitals in Costa Rica in 1996, germ cell tumor was the most frequent mediastinal tumor.¹²

¹³Diagnosis is performed when looking at an abnormal widening of the mediastinum and CT scan provides valuable information regarding the particular characteristics of the tumor, especially to plan the route to take a biopsy or to perform a surgical approach.¹⁴
