Resumen

El carcinoma de células pequeñas (CCP) prostático es un tumor infrecuente (menos del 1% de todas las neoplasias prostáticas) y por lo tanto son escasos los artículos que describen los aspectos diagnósticos y terapéuticos más importantes de estos tumores (menos de 200 casos publicados en la literatura). Los CCP prostáticos son un grupo heterogéneo de tumores, algunos con diferenciación neuroendocrina, y tienen un alto potencial maligno siendo habitual hallar metástasis viscerales en el momento del diagnóstico. El tratamiento con quimioterapia ha obtenido en algunos casos una remisión completa transitoria, pero el pronóstico es muy sombrío, con una supervivencia media entre los 5 y los 17,5 meses desde el momento del diagnóstico.

Presentamos dos nuevos casos de CCP prostático en estadio avanzado con mala respuesta al tratamiento y hacemos una revisión de la literatura.

Abstract

Pure small cell carcinoma of the prostate is rare (less than 1% of all prostatic neoplasm). As a result there are few reports in the literature that describe the salient features and appropiate management of this cancer (less than 200 cases reported). Small cell carcinomas of the prostate are a heterogeneous group of tumors, a number of them have neuroendocrine differentiation and are highly agressive, commonly with visceral metastases at time of diagnosis. Complete temporary remission has been reported with chemotherapy but this tumor has a poor prognosis. The median overall survival from the time of diagnosis is between 5-17.5 months.

We report 2 new cases of small cell carcinoma of the prostate and a review of the literature.

Key words:
Small cell carcinoma
Prostate
