Non-small-cell lung cancer (NSCLC) represents 85% of lung cancer. The most frequent sites of distant metastasis are the liver, adrenal glands, bones and brain. Gastrointestinal metastases are uncommon and rectal metastases are extremely rare. Here we report a case of squamous cell carcinoma of the lung with rectal metastases.
Observation and follow-up with PSA and rectal exam appears to be a good option for T1a clinical stage, given the good prognosis. Our results show that patients with T1a clinical stage and good prognostic factors could be at a similar risk of suffering from a new prostate cancer as the normal population, although prospective studies are required to validate these results. T1b cases require active treatment and closer monitoring.
RESUMEN
CARCINOMA TRANSICIONAL PRIMARIO PURO DE PRÓSTATA. REVISIÓN DE NUESTRA SERIEEl carcinoma transicional primario de próstata es un tumor raro que ocupa alrededor del 1% de los tumores de próstata.Presentamos seis casos diagnosticados en nuestro hospital hasta finales del año 2002. En todos ellos se descartó el origen vesical de la neoplasia.Nuestro objetivo es estudiar los datos de progresión y supervivencia en los carcinomas primarios puros (sin componente de adenocarcinoma) tratados en nuestro centro en los últimos años.En nuestra experiencia se trata de una neoplasia de pronóstico ominoso con una mediana de supervivencia de 4,6 meses. Con tendencia precoz a metastatizar a distancia. Por tanto, sugerimos la realización de cirugía radical prostática (sin cistectomía) en aquellos casos en los cuales no se evidencia enfermedad en la vejiga.PALABRAS CLAVE: Carcinoma transicional. Próstata. Pronóstico.
ABSTRACTPURE PRIMARY PROSTATE TRANSITIONAL CELL CARCINOMA. A REVIEW OF OUR SERIE Primary prostate transitional cell carcinoma is a very uncommon tumor, that represents about 1% of all prostate tumours. In our institution, only six patients have been diagnosed with pure transitional cell prostate carcinoma until 2002. Bladder origin of the neplasic was ruled out in all cases.We report a study about the progression and survival of prostate transitional cell carcinoma. These prostatic tumours carry a poor prognostic (median survival is 4.6 months) with a strong tendency to metastatic spread. Therefore, we suggest a radical prostatectomy (without cystectomy) when it rules out bladder origin tumour. O OR RI IG GI IN NA AL L E l carcinoma primario puro de próstata es una neoplasia muy poco frecuente, con un comportamiento biológico diferente al carcinoma acinar, con gran capacidad de metastatizar precozmente a distancia y por tanto con muy mal pronóstico 1 . Respecto al tratamiento son pocas las directrices terapéuticas disponibles en la literatura, motivo que nos lleva a la revisión de nuestra serie y a un planteamiento terapéutico.
