ABSTRACT

Introducción y objetivos: Este estudio tiene como objetivo investigar la relación entre la invasión perineural (IPN) en la biopsia de próstata con aguja dirigida (BD) y/o sistemática (BS) y las características patológicas adversas del cáncer de próstata (CaP) en los especímenes de prostatectomía.Materiales y métodos: Se incluyeron un total de 95 pacientes varones que recibieron una BD transperineal y/o una BS concomitante, tratados posteriormente con prostatectomía radical asistida por robot para CaP entre octubre de 2015 y junio de 2020. Se calculó el rendimiento de la IPN como prueba de clasificación (sensibilidad, especificidad, valores predictivos positivos y negativos) y su correlación con el CaP clínicamente significativo, la positividad del margen quirúrgico, la extensión extraprostática y la invasión de las vesículas seminales en la prostatectomía.Resultados: La edad media de los pacientes era 65 (60-70) años. Se realizó BD y BS concomitante en 78 (82,1%) pacientes, mientras que 16 (16,8%) pacientes recibieron solo BS y uno (1,1%) solo BD. La frecuencia de IPN en la BD y BS fue de 17 (21,5%) y 32 (34,0%), respectivamente. Los valores de especificidad/predictivos negativos de la IPN para positividad del margen quirúrgico, extensión extraprostática e invasión de las vesículas seminales fueron 79,7/88,7%, 92,5/79,0% y 83,3/96,8%, en la BD, y 71,1/87,1%, 80,7/74,2% y 69,5/91,9%, en la BS, respectivamente. También hubo una correlación estadísticamente significativa entre la IPN en la biopsia y la positividad del margen quirúrgico, la extensión extraprostática y la invasión de las vesículas seminales en la prostatectomía, así como en cuanto al grupo de grado ISUP y el estadio pT.Conclusiones: La ausencia de IPN en la biopsia de próstata con aguja puede predecir un CaP localizado con un estadio pT≤2c y márgenes quirúrgicos negativos; por el contrario, su presencia parece ser un indicador de factores desfavorables en la patología final (AU)


Introduction and objectives: This study aims to investigate the relationship between perineural invasion (PNI) in targeted (TBx) and/or systematic (SBx) prostate needle biopsy and adverse pathological features of prostate cancer (PCa) in prostatectomy specimens.Materials and methods: A total of 95 male patients who underwent transperineal TBx and/or concomitant SBx subsequently treated with robot-assisted radical prostatectomy for PCa between October 2015 and June 2020 were included. The performance of PNI as a classification test (sensitivity, specificity, positive and negative predictive values) and its correlation with clinically significant PCa, surgical margin positivity, extraprostatic extension, and seminal vesicle invasion in prostatectomy were computed.Results: The median age of the patients was 65 (60-70) years. TBx and concomitant SBx were performed in 78 (82.1%) patients, while 16 (16.8%) patients underwent SBx alone and one (1.1%) patient underwent TBx alone. The frequency of PNI in TBx and SBx was 17 (21.5%) and 32 (34.0%), respectively. The specificity/negative predictive values of PNI for surgical margin positivity, extraprostatic extension, and seminal vesicle invasion were 79.7/88.7%, 92.5/79.0%, and 83.3/96.8%, in TBx, and 71.1/87.1%, 80.7/74.2%, and 69.5/91.9%, in SBx, respectively. There was also a statistically significant correlation between PNI in biopsy and surgical margin positivity, extraprostatic extension, and seminal vesicle invasion in prostatectomy as well as the ISUP grade group and pT stage.Conclusions: The absence of PNI in prostate needle biopsy may predict localized PCa with a pT stage≤2c and negative surgical margins in contrast to its presence which appears to be an indicator of unfavorable factors in final pathology (AU)

ABSTRACT

El síndrome de Zinner es una rara entidad urológica caracterizada por la dilatación quística unilateral de una vesícula seminal junto con atrofia o agenesia renal ipsilateral. Los pacientes permanecen asintomáticos en la mayoría de los casos y su diagnóstico es incidental. El tratamiento de elección es quirúrgico cuando presentan sintomatología o se ve afectada la fertilidad del paciente. Presentamos el caso de un paciente de 13 años, monorreno de nacimiento, asintomático, sin otros antecedentes personales de interés, al que, durante un examen rutinario de su patología de base, se le realiza ecografía abdominal en la que se visualiza un probable quiste ureteral con una dilatación de la vesícula seminal compatible con un probable síndrome de Zinner.(AU)


Zinner syndrome is a rare urological entity characterized by unilateral cystic dilation of a seminal vesicle together with atrophy or ipsilateral renal agenesis. Patients remain asymptomatic in most cases and their diagnosis is incidental. The treatment of choice is surgical when symptoms occur or affect the patient´s fertility. We report the case of a 13-year-old asymptomatic boy born with a single-kidney with no other personal history of interest. During a routine examination of his underlying pathology, abdominal ultrasound was performed where a probable ureteral cyst with seminal vesicle dilation compatible with probable Zinner syndrome was observed.(AU)

ABSTRACT

Se presenta el caso de un niño de 14 años que hizo una consulta de control por un encondroma en el fémur izquierdo. La resonancia magnética (RM) de caderas reveló, accidentalmente, un quiste gigante de la vesícula seminal derecha. Si bien se indicó una urografía por RM, esta fue suspendida por un cuadro de claustrofobia del paciente y se realizó una tomografía computada abdómino-pélvica con y sin contraste endovenoso. La patología de las vesículas seminales (VS) puede clasificarse en congénita o adquirida. El primer tipo tiene baja prevalencia (siendo el quiste y la agenesia los más comunes en la práctica diaria) y puede coexistir, a menudo, con anomalías ipsilaterales del tracto urinario superior y genital, debido a la estrecha relación en los hombres de los sistemas reproductor y urinario durante la embriogénesis. También se ha descrito su vinculación con anomalías óseas y vasculares. La escasa frecuencia de presentación y el amplio espectro de potenciales hallazgos asociados suelen dificultar el diagnóstico. Lo habitual es iniciar la evaluación con una ecografía abdominal o transrectal, según la edad y tolerancia del paciente, y continuar con una RM, aunque para confirmar los hallazgos pueden ser necesarios otros procedimientos, como la vesículo-deferentografía (VDG). Esta fue tradicionalmente el método de referencia para el diagnóstico, pero en la actualidad se aplica en casos seleccionados. El tratamiento de las malformaciones está restringido a pacientes sintomáticos y usualmente consiste en una vesiculectomía, con o sin extirpación del riñón displásico o hipoplásico.(AU)


The case is presented of a 14 year-old boy with a previous diagnosis of left femur enchondroma. The pelvic and hip magnetic resonance imaging (MRI) unexpectedly revealed a right giant seminal vesicle cyst. He was evaluated by performing abdominal-pelvic computed tomography, with and without intravenous contrast. The pathology of the seminal vesicles (SV) can be classified as congenital and acquired. The first type has low prevalence (cyst and agenesis being the most frequently encountered in daily practice) and often co-exists with ipsilateral abnormalities in the upper urinary tract and genital organs, due to the close relationship of the male reproductive and urinary systems during embryogenesis. The association with bone and vascular anomalies has also been described. Abdominal and trans-rectal ultrasound, followed by abdominal and pelvic MRI, are the most accurate methods for preoperative diagnosis. Vesiculo-de/erentography (traditionally the gold standard test for diagnosis) is only applied in selected cases. The treatment, vesiculectomy, with or without removal of dysplastic or hypoplastic kidney, is restricted to symptomatic patients.(AU)

ABSTRACT

OBJECTIVES: The involvement of seminal vesicles in prostate cancer can affect the prognosis and determine the treatment. The objective of this study was to determine whether we could predict its infiltration at the time of the prostate biopsy to know when to indicate the biopsy of the seminal vesicles. MATERIAL AND METHODS: observational retrospective study of 466 patients who underwent seminal vesicle biopsy. The indication for this biopsy was a prostate-specific antigen (PSA) level greater than 10 ng/ml or an asymmetric or obliterated prostatoseminal angle. The following variables were included in the analysis: PSA level, PSA density, prostate volume, number of cores biopsied, suspicious rectal examination, and preservation of the prostatoseminal angle, studying its relationship with the involvement of the seminal vesicles. RESULTS: Forty-one patients (8.8%) had infiltrated seminal vesicles and 425 (91.2%) had no involvement. In the univariate analysis, the cases with infiltration had a higher mean PSA level (P < .01) and PSA density (P < .01), as well as a lower mean prostate volume (P < .01). A suspicious rectal examination (20.7% of the infiltrated vesicles) and the obliteration or asymmetry of the prostatoseminal angle (33.3% of the infiltrated vesicles) were significantly related to the involvement (P < .01). In the multivariate analysis, we concluded that the probability of having infiltrated seminal vesicles is 5.19 times higher if the prostatoseminal angle is not preserved (P < .01), 4.65 times higher for PSA levels >19.60 ng/dL (P < .01) and 2.95 times higher if there is a suspicious rectal examination (P = .014). Furthermore, this probability increases by 1.04 times for each unit of prostate volume lower (P < .01). The ROC curves showed maximum sensitivity and specificity at 19.6 ng/mL for PSA and 0.39 for PSA density. CONCLUSIONS: In this series, greater involvement of seminal vesicles was associated with a PSA level ≥20 ng/ml, a suspicious rectal examination and a lack of prostatoseminal angle preservation.

ABSTRACT

Introducción: Estudios recientes en pacientes con cáncer de próstata (CP) en estadios precoces han propuesto preservar las VS en la prostatectomía radical (PR) por tener una baja probabilidad de infiltración tumoral, obteniendo una mejor potencia y continencia que en pacientes sometidos a PR “clásica”. El objetivo de esta comunicación fue identificar factores clínico-patológicos preoperatoriosasociados al hallazgo de VS comprometidas en la pieza quirúrgica definitiva. Secundariamente determinarla evolución en el tiempo de este estadio (T3b) y su influencia en la sobrevida libre de enfermedad. Materiales y Métodos: Se revisaron los registros de 632 pacientes con diagnóstico de CP sometidos a PR por enfermedad localizada (T1 - T2) entre 1999 al 2005 en el Hospital Universidad Católica de Chile (HUC) y 1990 al 2005 en el Hospital Sótero del Río (HST). La recidiva bioquímica y sobrevida fue certificada a través de registros clínicos, entrevista telefónica, certificados de defunción y mediciones seriadas de APE. Se definió como recidiva bioquímica a la medición de APE > 0,4 ng/ml. Las variables analizadas en la regresión fueron: la edad y porcentaje de cáncer en la biopsia transrectal como variables continuas y Ape preop (< 10, 10-20,> 20) y puntaje de gleason en la biopsia transrectal (< 7, 7, > 7) como variables categorizadas. Se determinó la sensibilidad (Sen), especificidad (Esp),curvas ROC y área bajo la curva (AUC) para definir el mejor valor de corte que se asociara a compromiso de VS. Resultados: Del total de la serie, 74 pacientes (11,7 percent) presentaron compromiso de VS. El análisis de regresión logística reveló que el porcentaje de cáncer y puntaje de Gleason en la biopsia transrectal fueron factores predictores independientes de compromiso de VS...


Introduction: Recent studies in patients with prostate cancer (PC) in early stages proposed seminalvesicles sparing in radical prostatectomy (RP) due to a low probability of infiltration and better continenceand potency results. The purpose of this communication was to identify preoperative clinical and pathological data associated with seminal vesicles prostate cancer involvement. Secondarily, weassessed the evolution of patients with stage (T3b) disease treated with seminal vesicle sparing(SVS) technique and its influence on disease-free survival. Materials and Methods: Retrospective analysis of data of 632 patients with PC who underwent RP for localized disease (T1 - T2) from 1999 to 2005 at HUC and from 1990 to 2005 at HST. Biochemical recurrence and survival were verified through clinical records, telephone calls and serial PSA measurements. Biochemical recurrence was defined as PSA >0.4 ng / ml. Variables in the regression analysis were: Age and percentage of cancer disease identified in cores from transrectal prostate biopsy were defined as continuous variables. Preop psa (<10 10-20,>20) and Gleason score on biopsy transrectal (<7, 7,> 7) were defined as categorical variables. sensitivity (Sen), specificity (Esp) and ROC curves were calculated to define the best cutting value to be associated with SVS. Results: Seventy four patients (11.7 percent) had received SVS. Logistic regression analysis revealed that the percentage of cancer and Gleason score on transrectal biopsy were independent predictive factors predicting successful surgery treatment with SVS. The best cutoff point using the percentage of cancer in transrectal biopsy was 14.4 percent, with a Sen of 54 percent...
