RESUMEN

Objetivo El objetivo de este trabajo es conocer experiencia inicial con la terapia térmica con vapor de agua (TTVA) para hiperplasia benigna de próstata (HBP) en los hospitales universitarios españoles, así como describir las diferencias en cuanto a técnica y seguimiento observadas entre los centros. Materiales y métodos Este estudio multicéntrico observacional retrospectivo recogió características basales, datos quirúrgicos, posoperatorios y seguimiento a los uno, tres, seis, 12 y 24 meses, incluyendo cuestionarios validados, variaciones flujométricas, complicaciones y la necesidad de tratamiento farmacológico y quirúrgico tras el procedimiento. También se analizaron los posibles desencadenantes de retención aguda de orina (RAO) en el posoperatorio. Resultados Se incluyeron un total de 105 pacientes. No se observaron diferencias entre los grupos con y sin RAO con respecto a tiempo de sondaje (cinco y 4,3 días respectivamente, p = 0,178), ni volumen prostático (47,9 y 41,4 g, respectivamente, p = 0,147). La mejoría media a los tres, seis, 12 y 24 meses en cuanto de flujo máximo fue de 5,3, 5,2, 4,2 y 3,8 mL/s, respectivamente. En cuanto a la eyaculación, se observa una mejoría en la misma a partir de los tres meses de seguimiento que se mantiene en el tiempo. Conclusiones El tratamiento mínimamente invasivo de HBP con TTVA presenta buenos resultados funcionales a 24 meses de seguimiento, sin afectación significativa de la función sexual y con una baja incidencia de complicaciones. Existen pequeñas variaciones principalmente en cuanto al posoperatorio inmediato entre los hospitales participantes en el estudio. (AU)

Aim The aim of this work is to evaluate the initial experience with water vapor thermal therapy (WVTT) for benign prostatic hyperplasia (BPH) in Spanish university hospitals, as well as to describe the differences in technique and follow-up between centers. Materials and Methods This retrospective observational multicenter study collected baseline characteristics, surgical, postoperative and follow-up data at 1, 3, 6, 12 and 24 months, including validated questionnaires, flowmetric variations, complications, and the need for pharmacological or surgical treatment following the procedure. Possible triggers for postoperative acute urinary retention (AUR) were also analyzed. Results A total of 105 patients were included. No differences were observed between the groups with and without AUR with respect to catheterization time (5 and 4.3 days respectively, p = 0.178), or prostate volume (47.9 gr and 41.4 gr respectively, p = 0.147). The mean improvement at 3, 6, 12 and 24 months in terms of peak flow was 5.3, 5.2, 4.2 and 3.8 ml/s, respectively. As for ejaculation, an improvement was observed after 3 months of follow-up and was maintained over time. Conclusions Minimally invasive treatment for BPH with WVTT shows good functional outcomes at 24 months follow-up, without significant impairment of sexual function and a low incidence of complications. There are minor inter-hospital variations, mainly in the immediate postoperative period. (AU)

AIM: The aim of this work is to evaluate the initial experience with water vapor thermal therapy (WVTT) for benign prostatic hyperplasia (BPH) in Spanish university hospitals, as well as to describe the differences in technique and follow-up between centers. MATERIALS AND METHODS: This retrospective observational multicenter study collected baseline characteristics, surgical, postoperative and follow-up data at 1, 3, 6, 12 and 24 months, including validated questionnaires, flowmetric variations, complications, and the need for pharmacological or surgical treatment following the procedure. Possible triggers for postoperative acute urinary retention (AUR) were also analyzed. RESULTS: A total of 105 patients were included. No differences were observed between the groups with and without AUR with respect to catheterization time (5 and 4.3 days respectively, P=.178), or prostate volume (47.9g and 41.4g respectively, P=.147). The mean improvement at 3, 6, 12 and 24 months in terms of peak flow was 5.3, 5.2, 4.2 and 3.8ml/s, respectively. As for ejaculation, an improvement was observed after 3 months of follow-up and was maintained over time. CONCLUSIONS: Minimally invasive treatment for BPH with WVTT shows good functional outcomes at 24 months follow-up, without significant impairment of sexual function and a low incidence of complications. There are minor inter-hospital variations, mainly in the immediate postoperative period.

RESUMEN

Objetivo: Determinar factores predictivos de recidiva bioquímica (RB) temprana, intermedia y tardía después de prostatectomía radical mínimamente invasiva en pacientes con cáncer de próstata localizado. Material y métodos: Se incluyeron 6.195 pacientes con cáncer de próstata cT1-3N0M0 intervenidos mediante prostatectomía radical laparoscópica (PRL) y robótica en nuestra institución entre 2000 y 2016. Ninguno recibió tratamiento adyuvante. La RB se definió como PSA ≥ 0,2 ng/dl. El tiempo hasta RB se dividió en terciles para identificar variables asociadas con recidiva temprana (< 12 meses), intermedia (12-36 meses) y tardía (> 36 meses). Se utilizaron modelos de regresión logística para determinar los factores de riesgo asociados en cada intervalo. Resultados: Se identificaron 1.148 (18,3%) pacientes con RB. La mediana de tiempo hasta la RB fue de 24 meses (RIQ: 0,98-53,18). El análisis multivariable mostró que el PSA preoperatorio, la invasión ganglionar, los márgenes positivos y la PRL se asociaron con recidiva precoz (todos p ≤ 0,029). La cirugía laparoscópica fue el único predictor de recidiva intermedia (p = 0,001). Los predictores de recidiva tardía incluyeron un score de Gleason patológico ≥7, estadio ≥pT3, márgenes positivos y PRL (todos con p ≤ 0,02). Conclusiones: Los pacientes con cáncer de próstata de alto riesgo pueden desarrollar recurrencia tardía y precisar un seguimiento a largo plazo. La identificación de pacientes con mayor PSA e invasión ganglionar tiene un importante papel predictivo en el primer año tras la cirugía. La asociación entre PRL y RB merece una evaluación adicional

Objective: To determine the predictors of early, intermediate and late biochemical recurrence (BR) following minimally invasive radical prostatectomy in patients with localised prostate cancer (PC). Material and methods: We included 6195 patients with cT1-3N0M0 prostate cancer treated using radical laparoscopic prostatectomy (RLP) and radical robot-assisted prostatectomy at our institution between 2000 and 2016. None of the patients underwent adjuvant therapy. BR is defined as PSA levels ≥0.2 ng/dL. The time to BR is divided into terciles to identify the variables associated with early (< 12 months), intermediate (12-36 months) and late (> 36 months) recurrence. We employed logistic regression models to determine the risk factors associated with each interval. Results: We identified 1148 (18.3%) patients with BR. The mdian time to BR was 24 months (IQR, 0.98-53.18). The multivariate analysis showed that preoperative PSA levels, lymph node invasion, positive margins and RLP are associated with early recurrence (P≤ .029 for all). Laparoscopic surgery was the only predictor of intermediate recurrence (P = .001). The predictors of late recurrence included a pathological Gleason score ≥ 7, stage ≥ pT3, positive margins and RLP (P≤.02 for all). Conclusions: The patients with high-risk prostate cancer can develop late recurrence and require long-term follow-up. Identifying patients with higher PSA levels and lymph node invasion has an important predictive role in the first year after surgery. The association between RLP and BR warrants further assessment

RESUMEN

Purpose: To evaluate predictive factors associated with detectable prostate-specific antigen (PSA) and describe clinical recurrence (CR) and cancer-specific mortality (CSM) after robot-assisted radical prostatectomy (RARP). Methods: The study included 2500 patients who were treated with RARP at a single institution between 2000 and 2016. All patients had clinically localized PCa. Patients were divided into two groups according to PSA value at 6 weeks after surgery: undetectable (n = 2271; PSA < 0.1 ng/dl) and persistently elevated (n = 229; PSA ≥ 0.1 ng/dl). The association between various covariates and: (1) detectable PSA and (2) CR was evaluated. Kaplan-Meier analyses estimated CR and CSM rates according to PSA persistence. Results: Inside the group of detectable PSA, 146 men (63.75%) received adjuvant treatments, 44 patients (19.21%) salvages therapies and 38 men (16.5%) experienced CR. Factors associated with aggressive disease predicted PSA persistence. Within patients with detectable PSA, pathologic stage ≥ pT3a (HR 2.71; p < 0.029) and to received adjuvant androgen deprivation therapy (ADT) due to bad prognosis tumors (HR 13.36; p < 0.001) were associated with CR. Overall 14 (0.56%) died of PCa. 5 and 10-year CSM rates were higher for patients with CR (9.6 and 23.7%, p < 0.001), and Gleason ≥ 8 (5.7 and 6.9%, p = 0.003). Conclusions: A detectable PSA is affected by factors associated with aggressive prostate cancer. Within men with persistent PSA, those with higher pathologic stage and who received adjuvant ADT are more likely to have CR. Patients with CR, Gleason ≥ 8, and those who received adjuvant ADT must have a close monitoring due to the high rate of mortality
