[Preliminary data of the Spanish contribution to the European Randomized Study on Screening of Prostate Cancer (ERSPC)]. / Datos preliminares de la contribución española al estudio randomizado europeo de screening del cancer de próstata (ERSPC).

OBJECTIVES: Data from the participation of our department in the ERSPC study in terms of detection and PSA diagnostic yield, staging, therapeutic management and mortality in the context of a multicentric randomized screening study for prostate cancer. METHODS: Patients were recruited between February 1996 and June 1999, randomized in screening and control arms, with several rounds for screening patients with four-year intervals, with PSA analysis and sextant prostate biopsy (t PSA > 4 ng/ml before May 1998, tPSA > 2.99 ng/ml after May 1998). These tests were not done in the control group. All deaths were studied (date and cause) RESULTS: A total of 4278 patients were included, 24 16 in the screening arm (56.4%) and 1862 in the control arm (43.5%), with an age between 45 and 70 years (mean age 57.8 years, 95 CI 57.6-58.0). Median follow-up was 8.77 years. 142 prostate cancers were found, 113 in the screening arm (accumulated detection rate 4.7%) and 29 in the control arm (1.6%). Detection rates were 1.7%, 2.2% and 0% in the first, second and third round respectively. Organ confined cancers (T1 and T2) were 102 in the screening arm (90.3%) and 24 in the control arm (82.8%), p = 0.254 . Metastatic disease was found in six patients (4.2% out of 142), 3 in the screening arm ( 2.7%) and three in the control arm (10.3%), p = 0.187. Radical prostatectomy was the most frequently performed treatment: 47 cases in the screening arm (41.6%), 10 in the control arm (34.5%). 151 patients have died, 82 in the screening arm and 69 in the control arm. Only 3 of this deaths were secondary to prostate cancer, all of them in the screening arm (p = 0.308). CONCLUSIONS: We observed a non significant tendency to lower clinical stages in patients undergoing screening. Radical surgery was the treatment of choice in patients with prostate cancer. Even with the current follow-up in the series (close to 9 years), no differences have been observed in terms of prostate cancer mortality between both study arms.

OBJETIVO: Datos de la participación de nuestro Centro en el ERSPC en términos de detección y rendimiento diagnóstico del PSA, estadiaje, manejo terapéutico y mortalidad, en el contexto de un estudio multicéntrico randomizado de screening del cáncer de próstata (CaP). MÉTODOS: Se reclutaron pacientes entre febrero de 1996 y junio de 1999, randomizando en brazos screening y control, realizado varias rondas a los pacientes del brazo screening con intervalo de 4 años, con determinación de PSA y biopsia prostática sextante (PSAt >4ng/mL hasta mayo de 1998, posteriormente PSAt >2.99ng/mL), sin realizar dichos tests en los varones del grupo control. Se investigaron los fallecimientos (fecha de defunción y causa de la misma). RESULTADOS: Se incluyeron un total de 4.278 pacientes, 2.416 del brazo screening (56,4%) y 1.862 del brazo control (43,5%), con edad entre 45 a 70 años y media de 57,8 años (IC95 57,6-58,0). La mediana del tiempo de seguimiento fue de 8,77 años. Se encontraron 142 cánceres, 113 del brazo screening (tasa de detección acumulada 4,7%) y 29 del brazo control (1,6%). Las tasas de detección fueron de 1,7%, 2,2% y 0% en la primera, segunda y tercera ronda respectivamente. Los cánceres órgano confinados (T1 y T2) fueron 102 en el brazo screening (90,3%) y 24 en el control (82,8%), p=0,254. Se detectaron 6 pacientes con enfermedad metastásica (4,2% de 142), 3 del brazo screening (2,7%) y 3 del control (10,3%), p=0,187. El tratamiento más realizado fue la prostatectomía radical: 47 del brazo screening (41,6%) y 10 del control (34,5%). Se han producido 151 fallecimientos, 82 en el brazo screening y 69 en el control, de estos sólo 3 fallecimientos por CaP, todos del brazo screening (p=0,308). CONCLUSIONES: Se observa tendencia no significativa hacia estadíos clínicos más precoces en los pacientes sometidos a screening. El tratamiento de elección en los pacientes con CaP fue la cirugía radical. Aún con el seguimiento actual de esta serie (cercano a los 9 años), no se han observado en nuestro Centro diferencias en cuanto a la mortalidad por CaP entre los dos brazos del estudio

[Renal carcinoma metastatic to the peritoneum. Case report]. / Carcinoma renal metastásico a peritoneo. A propósito de un caso.

OBJECTIVE: We describe the case of a young male presenting with non-specific abdominal symptoms on follow-up after radical nephrectomy for renal carcinoma leading to the finding of local recurrence and peritoneal metastases. A second exploratory laparotomy was carried out for tumor reduction, but it was followed by fast peritoneal recurrence. Despite the treatment with alpha interferon, three months later he developed multiple hepatic metastases. CONCLUSIONS: Peritoneal involvement by renal cell carcinoma is rare and implies a bad prognosis.

Carcinoma renal metastásico a peritoneo. A propósito de un caso / Renal carcinoma metastatic to the peritoneum. Case report

OBJETIVO: Aportar un caso de carcinoma renal que presentó implantes peritoneales en su evolución. MÉTODO/RESULTADOS: Describimos el caso de un varón joven que en el seguimiento de su patología neoplásica tras nefrectomía radical presenta sintomatología abdominal inespecífica que conduce al descubrimiento de implantes peritoneales y recidiva local. Se realizó una segunda cirugía exploradora y de citorreductora, con recidiva peritoneal rápida. A los tres meses y a pesar del tratamiento que siguió con Interferón-α, el paciente presento metástasis hepáticas múltiples. CONCLUSIONES: La afectación peritoneal por carcinoma de células renales es un hecho infrecuente y que confiere un mal pronóstico

[Post chemotherapy laparoscopic retroperitoneal lymph node dissection]. / Linfadenectomía retroperitoneal vía laparoscópica postquimioterapia.

OBJECTIVES: To describe the laparoscopic excision of a postchemotherapy retroperitoneal residual mass in a patient with mixed germ cell testicular tumor. METHODS/RESULTS: We report the operative technique of laparoscopic excision of a retroperitoneal mass in a 33 year old patient with mixed germ cell testicular tumor. The patient is placed in a lateral decubitus right lumbotomy position and trocars are introduced into the abdominal cavity. Once the retroperitoneum is approached, and after a Kocher manoeuvre of the duodenum, the interaortocaval mass is identified and excised. The operation is completed with lympadenectomy down to the common iliac artery bifurcation bilaterally. CONCLUSION: The laparoscopic approach is another option for the surgical treatment of residual masses after chemotherapy in testicular tumors. Nevertheless, previous laparoscopic experience is necessary due to its difficulty.

[Right transperitoneal laparoscopic nephroureterectomy]. / Nefroureterectomía derecha laparoscópica vía transperitoneal.

OBJECTIVES: To describe the surgical technique of the right laparoscopic nephroureterectomy. METHODS/RESULTS: With the patient in the lithotomy position we performed an endoscopic section of the ureteral meatus. Once the patient is placed in the lumbotomy position and trocars are placed, the retroperitoneal space is accessed. The gonadal vein, and the ureter medial to it, are identified. We proceed to dissect and clip it. Posteriorly, the Kocher maneuver on the duodenum is performed, identifying the inferior vena cava. We dissect the renal artery and vein placing Hemolock clips on both. Once the vascular control is achieved, we free the upper pole with the help of the Ligasure Atlas instrument. When the kidney is free we continue with the ureter down. CONCLUSIONS: Laparoscopic nephroureterectomy is a feasible technique for groups with experience in laparoscopic surgery.

Nefrourectomiía derecha laparoscópica vía transperitoneal / right transperitoneal laparoscopic nephroureterectomy

OBJETIVO: Describir la técnica quirúrgica para la realización de una nefroureterectomía por vía laparoscópica. MÉTODOS/RESULTADOS: Con el paciente en posición de litotomía se realiza desinserción endoscópica del meato ureteral. Una vez colocado el paciente en posición de lumbotomía e introducidos los trócares, se accede al espacio retroperitoneal. Se identifica la vena gonadal y más medial el uréter. Procedemos a su disección y clipado precoz. Posteriormente se realiza la maniobra de Kocher sobre el duodeno, identificándose la vena cava. Disecamos la vena y arteria renal colocando clips Hemolock® en ambas. Con el control vascular realizado, liberamos el polo superior de riñón, ayudándonos de la pinza Atlas de Ligasure®. Una vez liberado todo el riñón, realizamos la misma operación sobre el uréter hasta desinsertarlo completamente. CONCLUSIÓN: La nefroureterectomía por vía laparoscópica es una técnica realizable en grupos con experiencia en cirugía laparoscópica

OBJETIVO: Describir la realización de la exéresis de una masa residual retroperitoneal post-quimioterapia, de un tumor germinal mixto por vía laparoscópica. MÉTODO/RESULTADOS: Presentamos la descripción técnica, por vía laparoscópica, de la exéresis de una masa residual post-quimioterapia de un tumor germinal mixto, en un paciente de 33 años. Se coloca al paciente en posición de lumbotomía derecha y se introducen los trócares. Una vez que se accede al retroperitoneo y realizada la maniobra de Kocher sobre el duodeno identificamos la masa residual interaorto-cava, procediendose a su exéresis. Por último se completa la disección, realizándose una linfadenectomía hasta la bifurcación de las arterias ilíacas primitivas. CONCLUSIÓN: La vía laparoscópica es una alternativa más para el tratamiento quirúrgico de las masas residuales post-quimioterapia en los tumores de testículo. No obstante precisa de experiencia en técnicas laparoscópicas debido a su dificultad

[Laparoscopic pyelolithotomy]. / Pielolitotomía laparoscópica.

The application of laparoscopy as a surgical technique in Urology has enabled to expand the therapeutic options for various pathologies. The treatment of urinary lithiasis localized in the renal pelvis is one of them. We report a laparoscopic pyelolithotomy, describing the operation step-by-step, from patient positioning and trochar insertion to drainage tube insertion and closure. The objective of this article is to show the technique, presenting it as an alternative option.

[Diet and bladder cancer]. / Dieta y cáncer de vejiga.

OBJECTIVES: To perform an update on the bibliography about the influence of dietetic factors on bladder cancer. METHODS: Bibliography search in various databases (PubMed, Ovid) on each one of the dietetic agents that can influence on the incidence of bladder tumors. RESULTS/CONCLUSIONS: There is a growing number of evidences that a great number of substances present in our usual diet have an influence on bladder cancer.

[Impact of the weather on the serum levels of prostatic specific antigen (PSA)]. / Impacto de la climatología sobre el nivel sérico de antígeno especifico prostático (PSA).

OBJECTIVES: To analyze the impact of season and weather parameters on serum PSA values in men without prostate cancer. METHODS: Retrospective study including medical records from the Spanish arm of the European Randomized Study of Screening for Prostate Cancer (ERSPC). EXCLUSION CRITERIA: prostate cancer diagnosis, PSA > = 10 ng/ml, or PSA > = 3 ng/ml and/or digital rectal examination abnormalities unless a negative prostate biopsy was provided. Univariate relationships between PSA value, season and several weather parameters were assessed. A multivariate logistic regression model was used to identify independent predictors of a PSA value > = 3 ng/ml. RESULTS: A total of 2,147 men entered into the study. Median age and PSA level were 57 years and 0.9 ng/ml respectively. A non-significant trend to higher PSA levels was observed during autumn and winter. Multivariate logistic regression analysis identified only maximum temperature (p < 0.001), minimum temperature (p = 0.001) and age (p < 0.001) as independent predictors of a PSA value > = 3 ng/ml. Mean age-adjusted PSA levels at maximum temperatures of < = 15 degrees C, 16-20 degrees C, 21-25 degrees C and > =26 degrees C were 1.25, 1.20, 1.17 and 1.09 ng/ml respectively. CONCLUSIONS: PSA levels are slightly higher during cold weather conditions. Because of the small magnitude of this PSA increment we do not recommend to change biopsy indication based solely on climatic parameters.

Impacto de la climatología sobre el nivel sérico de antígeno específico prostático (PSA) / Impact of the weather on the serum levels of prostatic specific antigen (PSA)

OBJETIVO: Analizar el impacto de la estación climática y de ciertos parámetros meteorológicos sobre el nivel de PSA sérico en varones sin cáncer de próstata. MÉTODOS: Estudio retrospectivo que incluye registros de la rama Española del European Randomized Study of Screening for Prostate Cancer (ERSPC). Los criterios de exclusión fueron el diagnóstico de cáncer de próstata, presentar PSA >= 10 ng/ml, o bien PSA >= 3 ng/ml y/o anomalías en el tacto rectal a menos que se disponga de una biopsia prostática negativa para malignidad. Se investigó la relación univariante entre nivel de PSA y estación climática, así como varios parámetros meteorológicos. Se empleó un modelo multivariante de regresión logística para identificar predictores independientes de la obtención de un nivel de PSA >=3 ng/ml. RESULTADOS: Un total de 2.147 varones fueron incluidos en el estudio. Las medianas de edad y PSA fueron 57 años y 0,9 ng/ml respectivamente. Se observó una tendencia no significativa hacia niveles de PSA más elevados durante las estaciones de otoño e invierno. El modelo multivariante de regresión logística identificó únicamente las temperaturas máxima (p= 3 ng/ml. Los niveles medios de PSA ajustado a la edad en los rangos de temperatura máxima =26ºC fueron 1,25, 1,20, 1,17 y 1,09 ng/ml respectivamente. CONCLUSIONES: Los niveles de PSA sérico son ligeramente más elevados durante condiciones de frío climático. Debido a la pequeña magnitud de esta elevación, no recomendamos cambiar la indicación de biopsia prostática basándonos únicamente en factores climáticos

[Cystic ectasia of the rete testis]. / Ectasia quística de la rete testis.

OBJECTIVES: The cystic ectasia of the rete testis is a benign entity with a typical ultrasound appearance as a collection of small hypoechoic structures in the confluence of the mediastinum testis. The clinical importance of these entity remains on doing an adequate differential diagnosis with testicular neoplasias with a cystic component. METHODS: We retrospectively reviewed the database of the Ultrasound Unit in the Department of Urology looking for patients with a diagnosis of cystic ectasia of the rete testis over a six-year period. RESULTS: Three cases of cystic ectasia of the rete testis were diagnosed over the six-year period, in all the indication for ultrasound was testicular pain. Mean patient age was 62 years. No patient developed testicular tumor on follow-up. CONCLUSIONS: The knowledge of the ultrasound characteristics found in the cystic ectasia of the rete testis helps to make a proper diagnosis of this benign entity without the need of indication of testicular biopsy.

[Testicular microlithiasis]. / Microlitiasis testicular.

OBJECTIVES: Testicular microlithiasis, characterized by the existence of microscopic calcifications within the seminiferous tubules, is rare, generally an incidental finding during a scrotal ultrasound. METHODS: We report the case of a 45-year-old male without risk factors for the development of a germ cell testicular tumor with the diagnosis of bilateral testicular microlithiasis. RESULTS: The patient was followed yearly with testicular ultrasound, without evidence of germ cell tumor over a four-year follow-up period. CONCLUSIONS: Although the clinical significance of testicular microlithiasis is under debate due to the various controversies found in the literature about its association or not with testicular tumors, as well as the various protocols for initial management and adequate intervals for follow-up, it seems reasonable to perform an ultrasound yearly independently of the existence or not of associated risk factors.
