ABSTRACT

Se presenta el caso de un paciente masculino de 73 años de edad operado por adenocarcinoma del antro gástrico. Se practicó gastrectomía subtotal distal más linfadenectomía D2. Durante el examen anatomopatológico de la pieza quirúrgica se encontró otro tumor pequeño en el espesor de la pared del antro cubierto por mucosa normal, separado del adenocarcinoma. El análisis histológico confirmó otra neoplasia incidental sincrónica, un tumor del estroma gastrointestinal de tipo fusiforme, positivo para el marcador tumoral CD117. El objetivo del trabajo es presentar esta asociación tumoral sincrónica, revisar sus características y las teorías etiopatogénicas actuales de esta condición sincrónica según la literatura especializada(AU)


A case is presented of a 73-year-old male patient who was operated for a gastric adenocarcinoma of the antrum. A distal subtotal gastrectomy plus D2 lymphadenectomy were practiced. During the anatomic and pathologic examination of the surgical piece, a second tiny tumor was found in the wall of the antrum and that was covered with a normal mucosa separated from the adenocarcinoma. The histologic examination confirmed another synchronous incidental neoplasm, a spindle-cell gastrointestinal stromal tumor, positive for the tumor marker CD117. This paper is aimed at presenting synchronous tumor entity, to review its characteristics and the current etiologic and pathogenic theories of this synchronic condition according to the specialized literature(AU)

ABSTRACT

El tratamiento del cáncer vesical de células transicionales con invasión muscular sigue siendo difícil, debido a los múltiples patrones de comportamiento biológico que muestra esta enfermedad. Existe controversia en cuanto a la aplicación de tratamiento sistémico en cáncer invasor vesical y el tiempo ideal de indicación de la quimioterapia perioperatoria. Se presenta una visión general de la terapia sistémica en cáncer invasor vesical.


Defining adequate therapy in every patient with invasive transitional cell carcinoma remains difficult, because multiple biologic behavior patterns can be found in this disease. There is controversy regarding the use of systemic treatment in invasive bladder carcinoma and the momentum for chemotherapy deployment. We present an overview of current trends for systemic treatment in bladder carcinoma.
