Cumulative morbidity of ureteroscopy for upper tract urothelial carcinoma.

OBJECTIVE: To assess complications after ureteroscopy (URS) for upper tract urothelial carcinoma (UTUC) management and to assess its postoperative cumulative morbidity burden using the Comprehensive Complication Index (CCI). MATERIALS AND METHODS: Single center retrospective study including patients submitted to URS for UTUC suspicion. URSs were both diagnostic and operative. Postoperative complications were recorded according to the EAU Guidelines and graded according to Clavien-Dindo Classification (CDC). The cumulative postoperative morbidity burden developed by patients experiencing multiple events was assessed using the CCI. Multivariable logistic regression (MLR) analyses identified factors independently associated with the development of any grade and major postoperative complications. RESULTS: Overall, 360 patients with UTUC suspicion were included with a total of 575 URSs performed. The cumulative number of all postoperative complications recorded was 111. In 86 (15%) procedures, patients experienced at least one postoperative complication, while 25 (4.3%) experienced more than one complication. Of these, 16 (14%) were severe (CDC ≥ IIIa). The most frequent type of complications were urinary (34%), bleeding (30%) and infectious (30%). The higher the CDC grade, the higher the median CCI, with a statistically significant increase in median CCI from CDC II to major complications. Patients who experienced intraoperative complications were at higher risk of developing any grade and major postoperative complications at MLR. CONCLUSIONS: Complications after ureteroscopy for UTUC are relatively uncommon events. Patients who experience intraoperative complications are at higher risk of developing postoperative complications. The comprehensive complication index appeared more representative of the cumulative postoperative morbidity rather than the Clavien-Dindo classification.

Apalutamide for prostate cancer: Multicentre and multidisciplinary real-world study of 227 patients.

OBJECTIVE: To evaluate the efficacy and safety of apalutamide prostate cancer compared to the pivotal trials patients and to identify the first subsequent therapy in a real-world setting. METHODS: The study is prospective and observational based on real-world evidence, performed by different medical disciplines and eight academics centres around Barcelona, Spain. It included all patients with metastatic hormone-sensitive prostate cancer (mHSPC) and high-risk non-metastatic castration-resistant prostate cancer (nmCRPC) treated with apalutamide from June 2018 to December 2022. RESULTS: Of 227 patients treated with apalutamide, 10% had ECOG-PS 2, and 41% were diagnosed with new-generation imaging. In the mHSPC group (209 patients), 75 years was the median age, 53% had synchronous metastases, and 22% were M1a. In the nmCRPC (18 patients), 82 years was the median age, and 81% ≤6 months had PSA doubling time. Patients achieved PSA90 in 92% of mHSPC and 50% of nmCRPC and PSA ≤0.2 in 71% of mHSPC and 39% of nmCRPC. Treatment-related adverse events occurred in 40.1% of mHSPC and 44.4% of nmCRPC. After discontinuation of apalutamide due to disease progression, 54.5% in mHSPC and 75% in nmCRPC started chemotherapy, while after discontinuation because of adverse events, 73.3% in mHSPC and 100% in nmCRPC continued with other hormonal-therapies. CONCLUSIONS: The efficacy and safety of apalutamide were similar to that described in the pivotal trials, despite including an older and more comorbid population. Usually, subsequent therapies after apalutamide differed depending on the reason for discontinuation: by disease progression started chemotherapy and by adverse events hormonal sequencing.

Indicaciones e histología de 489 orquiectomías analizadas según la edad del paciente / Indications and histology of 489 orchiectomies analyzed by patient age

Objetivo Evaluar indicaciones e histología de nuestra serie de orquiectomías, analizando los resultados dependiendo de la edad del paciente. Métodos Estudio de las orquiectomías realizadas en nuestro centro entre 2005 y 2020 a pacientes mayores de 18 años. Evaluamos: datos demográficos, indicaciones, histología y efectividad del diagnóstico ecográfico según 3 grupos de edad. Resultados Se realizaron 489 orquiectomías, 364 (74%) en los pacientes entre 18-50 años (grupo A), 59 (12%) entre los pacientes de 51-70 años (grupo B) y 66 (13,4%) en mayores de 70 años (grupo C). En el grupo A, 284 (78%) orquiectomías fueron indicadas por sospecha tumoral, 261/284 (91,9%) fueron neoplasias malignas, 253 (89%) germinales. La ecografía testicular tuvo un valor predictivo positivo (VPP) para tumor testicular maligno del 90%. En el grupo B, 34 (57%) orquiectomías fueron indicadas por sospecha tumoral y 25/34 (73,5%) presentaron neoplasias malignas. La ecografía tuvo un VPP para malignidad del 68%. En el grupo C, la orquiepididimitis fue la causa más frecuente de orquiectomía con 30 casos (45,5%). Entre las 20 orquiectomías por sospecha de tumor (30,3%), se encontró malignidad en 6. La ecografía tuvo un VPP para malignidad del 31%. Conclusión En menores de 70 años la indicación principal de orquiectomía fue la sospecha tumoral y en mayores, la orquiepididimitis. Los tumores germinales fueron la histología más frecuente en los menores de 70 años; en los mayores la malignidad fue infrecuente. Con la edad, disminuyó el VPP de la ecografía testicular para neoplasia maligna. En los mayores de 50 años se debería mejorar el proceso diagnóstico antes de indicar orquiectomía por sospecha tumoral (AU)

Objective To evaluate the indications and histology of our series of orchiectomies, analysing the results by patient's age. Methods We included the orchiectomies realized in our hospital between 2005 and 2020 in patients older than 18 years. We estimated demographic data, indications, histology and effectiveness of testicular ultrasound by three groups of age. Results We included 489 orchiectomies, which 364 (74%) belonged to group A (patients between 18-50 years), 59 (12%) to group B (50-70 years) and 66 (14%) to group C (older than 70 years). In group A, 284 (78%) orchiectomies were indicated due to malignancy suspect. In 91.9% cases (261) malign neoplasm was confirmed at final histology and 253 (89%) were germinal cells. Testicular ultrasound had a positive predictive value (PPV) of 90% in this group. In group B, 34 (57%) orchiectomies were indicated because of malignancy suspect. At final histologic analysis, 25/34 (73.5%) confirmed malign neoplasm. Ultrasound had a PPV of 68%. In group C, orchiepididymitis was the main cause of testicular removal with 30 cases (45,5%). From the 20 cases (30.3%) with suspicion of malignancy, only 6 had confirmed malign histology. Testicular ultrasound PPV for malignancy was 31%. Conclusion In patients younger than 70 years the main orchiectomy's indication was suspect of malignancy and in older than 70, testicular inflammation. The germinal neoplasm was the predominant histology in younger than 70 years. In older than that, malignancy was infrequent. The positive predictive value of testicular ultrasound for malignancy decreased with patient's age. In patients older than 50 years proper image diagnosis to assess malignancy should be considered before orchiectomy is done (AU)

Impacto clínico de no aplicar el protocolo ERAS en los pacientes sometidos a cistectomía durante la pandemia COVID-19 / Clinical impact of the suspension of the ERAS protocol on patients undergoing radical cystectomy during the COVID-19 pandemic

Introducción Al inicio de la pandemia por COVID-19 no se pudo implementar ni prehabilitación ni rehabilitación multimodal por sobrecarga del sistema sanitario. Nuestro objetivo fue analizar evolución, complicaciones y supervivencia hasta el año de pacientes sometidos a cistectomía radical en nuestro centro desde el 1 de marzo hasta el 31 de mayo de 2020 (primera ola). Comparamos resultados con pacientes también cistectomizados fuera de pandemia donde sí estaba instaurado el protocolo ERAS. Material y métodos Estudio de cohortes retrospectivo, unicéntrico, de pacientes programados para cistectomía radical desde el 1 de marzo de 2020 hasta el 31 de mayo de 2020; se emparejaron con pacientes intervenidos anteriormente a través de score de emparejamiento por propensión 1:2. Las variables de emparejamiento fueron datos demográficos, condiciones clínicas preoperatorias e intraoperatorias. Resultados Se realizaron 23 cistectomía en este periodo; en ningún caso se aplicó ni prehabilitación ni seguimiento del protocolo ERAS, y esta fue la única diferencia en el tratamiento entre grupos. Tres pacientes se diagnosticaron de COVID-19 durante su ingreso presentando complicaciones respiratorias graves y alta mortalidad intrahospitalaria. La tasa de transfusión sanguínea fue mayor en el grupo pandemia. La estancia hospitalaria aumentó en tres días en grupo pandemia. Conclusiones Los pacientes sometidos a cistectomía en nuestro centro durante la primera ola de pandemia por COVID-19 presentaron complicaciones respiratorias y no respiratorias en mayor número y más graves que los cistectomizados fuera de este periodo. La no aplicación del protocolo ERAS fue la principal diferencia en el tratamiento entre grupos (AU)

Introduction During the beginning of the COVID-19 pandemic in our center, neither prehabilitation nor multimodal rehabilitation could be applied due to the excessive patient load on the health system and to reduce SARS-CoV-2 transmission. The objective of our study was to analyze the evolution, complications, and survival up to one year of patients who underwent radical cystectomy in our hospital from March 1st to May 31st, 2020 (period of the first wave COVID-19 pandemic in Spain). We also compared the results with cystectomized patients outside the pandemic period and with application of the ERAS (Enhanced Recovery After Surgery) protocol. Material and methods Single-center, retrospective cohort study of patients scheduled for radical cystectomy from March 1st,2020 to May 31st, 2020. They were matched with previously operated patients using a 1:2 propensity matching score. The matching variables were demographic data, preoperative and intraoperative clinical conditions. Results A total of 23 radical cystectomies with urinary diversion were performed in the period described. In none of the cases the prehabilitation or the follow-up of our ERAS protocol could be applied, and this was the only difference we found between the 2 groups. Although the minimally invasive approach was more frequent in the pandemic group, the difference was not statistically significant. Three patients were diagnosed with COVID-19 during their admission, presenting severe respiratory complications and high in-hospital mortality. Apart from respiratory complications secondary to SARS-CoV-2, we also found statistically significant differences in other postoperative complications. The hospital stay increased by 3 days in the pandemic group (AU)

Diagnóstico incidental del cáncer de vejiga en España. Estudio observacional a nivel nacional / Incidental diagnosis of bladder cancer in a national observational study in Spain

Introducción El cáncer de vejiga (CV) es una neoplasia frecuente en España. Los objetivos de este estudio fueron: identificar la proporción de pacientes diagnosticados de CV de forma incidental o tras la presentación de síntomas en un periodo contemporáneo en España; comparar las características demográficas, clínicas y patológicas entre estos grupos. Métodos El presente fue un análisis retrospectivo de un estudio observacional multicéntrico realizado en 26 hospitales del Sistema Nacional de Salud español, incluyendo a todos los nuevos diagnósticos de CV en 2011. El estudio representó 21,5% de la población española y los hospitales fueron seleccionados de forma proporcional a las regiones españolas para asegurar una muestra representativa. Los pacientes fueron categorizados según el diagnóstico de cáncer incidental o tras la presentación sintomática y se analizaron las características demográficas, patológicas y clínicas basales. Resultados En los 26 hospitales españoles incluidos en el estudio, se diagnosticaron 2.472 casos de CV, de los cuales 308 (12,5%) fueron diagnosticados de forma incidental y 2.164 (87,5%) tras la presentación de síntomas. No se observaron diferencias entre los pacientes diagnosticados incidentalmente frente a los sintomáticos en términos demográficos o de comorbilidades evaluadas. En comparación con los tumores de vejiga con diagnostico posterior a la presentación de síntomas, los diagnósticos incidentales tenían más probabilidades de ser tumores papilares, significativamente más pequeños y de tener una citología positiva/sospechosa. Además, los tumores de vejiga diagnosticados incidentalmente tenían menos probabilidades de ser músculo-invasivos (11,7 vs. 25%, p < 0,01) y de ser agresivos en el estudio patológico, con 33,6% de grado 3 vs. 50,1% (p < 0,01). Conclusiones Identificamos un porcentaje significativo (12,5%) de nuevos diagnósticos de CV realizados de forma incidental en una muestra representativa de la población española (AU)

Introduction Bladder cancer (BC) is a common malignancy in Spain. The aims of this study were: to identify the proportion of patients diagnosed with BC incidentally or after symptomatic presentation in a contemporary period in Spain; to compare demographic, clinical, and pathologic characteristics between these groups. Methods This was a retrospective analysis of a multi-centre observational study of 26 hospitals in the Spanish National Health System of all BCs newly diagnosed in 2011. The study represented 21.5% of the Spanish population and hospitals were selected in proportion to Spain's regions to ensure a representative sample. Patients were categorized by whether the cancer was diagnosed incidentally or after symptomatic presentation and baseline demographic, pathologic, and clinical characteristics were analyzed. Results 2472 were newly diagnosed with BC at the 26 participating Spanish hospitals with 308 (12.5%) of cases diagnosed incidentally and 2164 (87.5%) diagnosed after symptomatic presentation. No differences were observed between patients diagnosed incidentally vs. symptomatically in terms of demographics or measured co-morbidities. Compared to symptomatically diagnosed bladder tumours, those diagnosed incidentally were more likely to have a papillary appearance, to be significantly smaller, and less likely to have positive/suspicious cytology. Additionally, incidentally diagnosed bladder tumours were less likely to be muscle-invasive (11.7% vs. 25.0%, P < .01) nor aggressive at pathology, with 33.6% Grade 3 compared to 50.1%, (P < .01). Conclusions We identified a significant percentage (12.5%) of new bladder cancer diagnosis made incidentally in a representative sample of the Spanish population. These tumours exhibited less aggressive pathologic characteristics than their symptomatic counterparts (AU)

Manejo del carcinoma in situ de tramo urinario superior diagnosticado por biopsia ureteroscópica: ¿es el bacilo de Calmette-Guérin una alternativa a la nefroureterectomía? / Management of primary upper urinary tract carcinoma in situ diagnosed by ureteroscopic biopsy: Is bacillus Calmette-Guerin an alternative to nephroureterectomy?

Introducción La nefroureterectomía radical (NFU) es el tratamiento estándar del carcinoma de tramo urinario superior (TUS). No obstante, desde 1985 se ha introducido el tratamiento conservador en el manejo del carcinoma in situ en TUS (cis-TUS). El objetivo de este estudio fue comparar la evolución oncológica de los pacientes con cis-TUS tratados en nuestro centro con NFU vs. instilaciones de bacilo de Calmette-Guérin (BCG). Métodos Se trata de un estudio retrospectivo de pacientes con diagnóstico de cis-TUS primario entre 1990-2018. Todos los pacientes presentaban diagnóstico histológico de cis-TUS con ausencia de otro carcinoma de TUS concomitante. La confirmación histológica se obtuvo mediante ureteroscopia con múltiples biopsias. Los pacientes fueron tratados mediante NFU, ureterectomía distal o instilaciones de BCG. Los datos clinicopatológicos y la evolución oncológica fue comparada entre los grupos NFU y BCG. Resultados Se incluyeron un total de 28 pacientes, 29 unidades renales (UR). Dieciséis (57,1%) pacientes (17 UR) recibieron BCG. Las instilaciones fueron administradas por nefrostomía en 4 pacientes, catéter en J simple en 5 y doble J en 7. La respuesta completa y la persistencia o recurrencia fueron detectadas en 10 (58,8%) y 7 (41,2) UR tratadas con BCG. Ocho UR (27,6%) fueron tratadas con NFU, con una recurrencia contralateral detectada en 4 casos (50%). Finalmente, 4 UR con cis-TUS (13,8%) fueron tratadas con ureterectomía distal. No se detectaron diferencias en la supervivencia libre de recurrencia (p=0,841) ni en la supervivencia cáncer específica (p=0,77) entre los grupos de NFU y BCG. Conclusiones Aunque la nefroureterectomía radical representa el tratamiento estándar para el CIS de tramo urinario superior, nuestros resultados confirman que las instilaciones con BCG también son efectivas. La confirmación histológica de cis-TUS debería realizarse previamente a la decisión terapéutica (AU)

Introduction Radical nephroureterectomy (RNU) still represents the gold standard treatment for upper tract urothelial carcinoma (UTUC); however, since the 1980s attempts have been made to treat upper urinary tract CIS (UT-CIS) conservatively. The aim of this study was to compare the outcome of patients with primary UT-CIS treated in our center by means of RNU vs. bacillus Calmette-Guérin (BCG) instillations. Methods This retrospective study included patients with diagnosis of primary UT-CIS between 1990 and 2018. All patients had histological confirmation of UT-CIS in the absence of other concomitant UTUC. Histological confirmation was obtained by ureteroscopy with multiple biopsies. Patients were treated with RNU, distal ureterectomy, or BCG instillations. Clinicopathological features and outcomes were compared between the RNU and BCG groups. Results A total of 28 patients and 29 renal units (RUs) were included. Sixteen (57.1%) patients (17 RUs) received BCG. BCG was administered via a nephrostomy tube in 4 patients, a single-J ureteral stent in 5, and a Double-J stent in 7. Complete response and persistence or recurrence were detected in ten (58.8%) and seven (41.2%) RUs treated with BCG, respectively. Eight (27.6%) RUs underwent RNU, with contralateral recurrence detected in four (50%), and 4 (13.8%) RUs underwent distal ureterectomy. No differences were found in recurrence-free survival (p=0.841) and cancer-specific survival (p=0.77) between the RNU and BCG groups. Conclusions Although RNU remains the gold standard treatment for UT-CIS, our results confirm that BCG instillations are also effective. Histological confirmation of UT-CIS is mandatory before any treatment (AU)

Reduced- vs full-dose BCG in bladder cancer: A systematic review and meta-analysis.

OBJECTIVE: To assess the oncologic outcomes and the safety profile of a reduced-dose versus full-dose BCG regimen in patients with non-muscle-invasive bladder cancer (NMIBC). MATERIAL AND METHODS: We performed a systematic review according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The PubMed, Embase, and Web of Science databases were searched in January 2022 for studies that analyzed oncological outcomes and compared between reduced- and full-dose BCG regimens. RESULTS: Seventeen studies including 3757 patients met our inclusion criteria. Patients who received reduced-dose BCG had significantly higher recurrence rates (OR 1.19; 95%CI, 1.03-1.36; p = 0.02). The risks of progression to muscle-invasive BC (OR 1.04; 95%CI, 0.83-1.32; p = 0.71), metastasis (OR 0.82; 95%CI, 0.55-1.22; p = 0.32), death from BC (OR 0.80; 95%CI, 0.57-1.14; p = 0.22), and all-cause death (OR 0.82; 95%CI, 0.53-1.27; p = 0.37) were not statistically different. When restricting the analyses to randomized controlled trials, we found similar results. In subgroup analysis, reduced dose was associated with a higher rate of BC recurrence in studies that used only an induction regimen (OR 1.70; 95%CI, 1.19-2.42; p = 0.004), but not when a maintenance regimen was used (OR 1.07; 95%CI, 0.96-1.29; p = 0.17). Regarding side effects, the reduced-dose BCG regimen was associated with fewer episodes of fever (p = 0.003), and therapy discontinuation (p = 0.03). CONCLUSION: This review found no association between BCG dose and BC progression, metastasis, and mortality. There was an association between reduced dose and BC recurrence, which was no longer significant when a maintenance regimen was used. In times of BCG shortage, reduced-dose regimens could be offered to BC patients.

Robot-assisted vs. open radical cystectomy: systematic review and meta-analysis of randomized controlled trials.

INTRODUCTION: Several randomized controlled trials (RCTs) have been launched in the last decade to examine the surgical safety and oncological efficacy of robot-assisted (RARC) vs open radical cystectomy (ORC) for patients with bladder cancer. The aim of the study was to perform a systematic review and meta-analysis of RCTs to compare the perioperative and oncological outcomes of RARC vs ORC. METHODS: A literature search was conducted through July 2022 using PubMed/Medline, Embase, and Web of Science databases. Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were followed to identify eligible studies. The outcomes were intraoperative, postoperative, and oncological outcomes of RARC vs ORC. RESULTS: A total of eight RCTs comprising 1,024 patients met our inclusion criteria. RARC was associated with longer operative time (mean 92.34min, 95% CI 83.83-100.84, p<0.001) and lower blood transfusion rate (Odds ratio [OR] 0.43, 95% CI 0.30-0.61, p<0.001). No differences emerged in terms of 90-day overall (p=0.28) and major (p=0.57) complications, length of stay (p=0.18), bowel recovery (p=0.67), health-related quality of life (p=0.86), disease recurrence (p=0.77) and progression (p=0.49) between the two approaches. The main limitation is represented by the low number of patients included in half of RCTs included. CONCLUSIONS: This study supports that RARC is not inferior to ORC in terms of surgical safety and oncological outcomes. The benefit of RARC in terms of lower blood transfusion rate need to be balanced with the cost related to the procedure.

[CLINICAL IMPACT OF THE SUSPENSION OF THE ERAS PROTOCOL ON PATIENTS UNDERGOING RADICAL CYSTECTOMY DURING THE COVID-19 PANDEMIC.] / IMPACTO CLÍNICO DE NO APLICAR EL PROTOCOLO ERAS EN LOS PACIENTES SOMETIDOS A CISTECTOMÍA DURANTE LA PANDEMIA COVID-19.

INTRODUCTION: During the beginning of the COVID-19 pandemic in our center, neither prehabilitation nor multimodal rehabilitation could be applied due to the excessive patient load on the health system and to reduce SARS-CoV-2 transmission. The objective of our study was to analyze the evolution, complications, and survival up to one year of patients who underwent radical cystectomy in our hospital from March 1st to May 31st, 2020 (period of the first wave COVID-19 pandemic in Spain). We also compared the results with cystectomized patients outside the pandemic period and with application of the ERAS (Enhanced Recovery After Surgery) protocol. MATERIAL AND METHODS: Single-center, retrospective cohort study of patients scheduled for radical cystectomy from March 1st,2020 to May 31st, 2020. They were matched with previously operated patients using a 1:2 propensity matching score. The matching variables were demographic data, preoperative and intraoperative clinical conditions. RESULTS: A total of 23 radical cystectomies with urinary diversion were performed in the period described. In none of the cases the prehabilitation or the follow-up of our ERAS protocol could be applied, and this was the only difference we found between the 2 groups. Although the minimally invasive approach was more frequent in the pandemic group, the difference was not statistically significant. Three patients were diagnosed with COVID-19 during their admission, presenting severe respiratory complications and high in-hospital mortality. Apart from respiratory complications secondary to SARS-CoV-2, we also found statistically significant differences in other postoperative complications. The hospital stay increased by 3 days in the pandemic group. CONCLUSIONS: Patients who underwent radical cystectomy at our center during the first wave of the COVID-19 pandemic had a higher number and severity of respiratory and non-respiratory complications. Discontinuation of the ERAS protocol was the main difference in treatment between groups.

Dosis reducida vs. dosis completa de BCG en el cáncer de vejiga: revisión sistemática y metaanálisis / Reduced- vs full-dose BCG in bladder cancer: a systematic review and meta-analysis

Objetivo Evaluar los resultados oncológicos y el perfil de seguridad de un régimen de Bacilo Calmette-Guérin (BCG) de dosis reducida frente a uno de dosis completa en pacientes con cáncer de vejiga no músculo infiltrante (CVNMI). Material y métodos Se realizó una revisión sistemática de acuerdo con la declaración Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Se realizaron búsquedas de estudios que analizaran los resultados oncológicos entre los regímenes de BCG con reducción de dosis y dosis completa en las bases de datos PubMed, Embase y Web of Science en enero del 2022. Resultados Diecisiete estudios que incluían a 3.757 pacientes cumplieron los criterios de inclusión. Los pacientes que recibieron reducción de dosis de BCG tuvieron tasas de recidiva significativamente mayores (OR 1,19; IC del 95%, 1,03-1,36; p = 0,02). Los riesgos de progresión a un cáncer de vejiga (CV) músculo infiltrante (OR 1,04; IC 95%, 0,83-1,32; p = 0,71), de metástasis (OR 0,82; IC 95%, 0,55-1,22; p = 0,32), de muerte por CV (OR 0,80; IC 95%, 0,57-1,14; p = 0,22) y de muerte por cualquier causa (OR 0,82; IC 95%, 0,53-1,27; p = 0,37) no fueron estadísticamente diferentes. Al restringir los análisis a ensayos controlados aleatorizados, se encontraron resultados similares. En el análisis de subgrupos, la reducción de dosis se asoció con una mayor tasa de recidiva de CV en los estudios que utilizaron solo un régimen de inducción (OR 1,70; IC 95%, 1,19-2,42; p = 0,004), lo cual no se observó cuando se empleó un régimen de mantenimiento (OR 1,07; IC 95%, 0,96-1,29; p = 0,17). En cuanto a los efectos secundarios, el esquema reducido de BCG se asoció con menos episodios de fiebre (p = 0,003) y de interrupción del tratamiento (p = 0,03). Conclusión Esta revisión no encontró ninguna asociación entre la dosis de BCG y la progresión, la metástasis y la mortalidad del CV (AU)

Incidental diagnosis of bladder cancer in a national observational study in spain.

INTRODUCTION: Bladder cancer (BC) is a common malignancy in Spain. The aims of this study were: to identify the proportion of patients diagnosed with BC incidentally or after symptomatic presentation in a contemporary period in Spain; to compare demographic, clinical, and pathologic characteristics between these groups. METHODS: This was a retrospective analysis of a multi-centre observational study of 26 hospitals in the Spanish National Health System of all BCs newly diagnosed in 2011. The study represented 21.5% of the Spanish population and hospitals were selected in proportion to Spain's regions to ensure a representative sample. Patients were categorized by whether the cancer was diagnosed incidentally or after symptomatic presentation and baseline demographic, pathologic, and clinical characteristics were analyzed. RESULTS: 2472 were newly diagnosed with BC at the 26 participating Spanish hospitals with 308 (12.5%) of cases diagnosed incidentally and 2164 (87.5%) diagnosed after symptomatic presentation. No differences were observed between patients diagnosed incidentally vs. symptomatically in terms of demographics or measured co-morbidities. Compared to symptomatically diagnosed bladder tumours, those diagnosed incidentally were more likely to have a papillary appearance, to be significantly smaller, and less likely to have positive/suspicious cytology. Additionally, incidentally diagnosed bladder tumours were less likely to be muscle-invasive (11.7% vs. 25.0%, p < 0.01) nor aggressive at pathology, with 33.6% Grade 3 compared to 50.1%, (p < 0.01). CONCLUSIONS: We identified a significant percentage (12.5%) of new bladder cancer diagnosis made incidentally in a representative sample of the Spanish population. These tumours exhibited less aggressive pathologic characteristics than their symptomatic counterparts.

Management of primary upper urinary tract carcinoma in situ diagnosed by ureteroscopic biopsy: Is bacillus Calmette-Guerin an alternative to nephroureterectomy?

BACKGROUND: Radical nephroureterectomy (RNU) represents the gold standard treatment for upper tract urothelial carcinoma (UTUC); however, attempts have been made to treat upper urinary tract CIS (UT-CIS) conservatively. The aim of this study was to compare the outcome of patients with primary UT-CIS treated in our center by means of RNU vs. bacillus Calmette-Guérin (BCG) instillations. METHODS: This retrospective study included patients with diagnosis of primary UT-CIS between 1990 and 2018. All patients had histological confirmation of UT-CIS in the absence of other concomitant UTUC. Histological confirmation was obtained by ureteroscopy with multiple biopsies. Patients were treated with BCG instillations, RNU or distal ureterectomy. Clinicopathological features and outcomes were compared between RNU and BCG groups. RESULTS: A total of 28 patients and 29 renal units (RUs) were included. Sixteen (57.1%) patients (17 RUs) received BCG. BCG was administered via nephrostomy tube in 4 patients, with a single-J ureteral stent in 5, and using a Double-J stent in 7. Complete response and persistence or recurrence were detected in ten (58.8%) and seven (41.2%) RUs treated with BCG, respectively. Eight (27.6%) RUs underwent RNU, and 4 (13.8%) Rus distal ureterectomy. No differences were found in recurrence-free survival (p=0.841) and cancer-specific survival (p=0.77) between the RNU and BCG groups. CONCLUSIONS: Although RNU remains the gold standard treatment for UT-CIS, our results confirm that BCG instillations are also effective. Histological confirmation of UT-CIS is mandatory before any treatment.

Indications and histology of 489 orchiectomies analyzed by patient age.

OBJECTIVE: To evaluate the indications and histology of our series of orchiectomies, analysing the results by patient's age. METHODS: We included the orchiectomies realized in our hospital between 2005 and 2020 in patients older than 18 years. We estimated demographic data, indications, histology and effectiveness of testicular ultrasound by three groups of age. RESULTS: We included 489 orchiectomies, which 364 (74%) belonged to Group A (patients between 18-50 years), 59 (12%) to Group B (50-70 years) and 66 (14%) to Group C (older than 70 years). In Group A, 284 (78%) orchiectomies were indicated due to malignancy suspect. In 91.9% cases (261) malign neoplasm was confirmed at final histology and 253 (89%) were germinal cells. Testicular ultrasound had a positive predictive value (PPV) of 90% in this group. In Group B, 34 (57%) orchiectomies were indicated because of malignancy suspect. At final histologic analysis, 25/34 (73.5%) confirmed malign neoplasm. Ultrasound had a PPV of 68%. In Group C, orchiepididymitis was the main cause of testicular removal with 30 cases (45,5%). From the 20 cases (30.3%) with suspicion of malignancy, only 6 had confirmed malign histology. Testicular ultrasound PPV for malignancy was 31%. CONCLUSION: In patients younger than 70 years the main orchiectomy's indication was suspect of malignancy and in older than 70, testicular inflammation. The germinal neoplasm was the predominant histology in younger than 70 years. In older than that, malignancy was infrequent. The positive predictive value of testicular ultrasound for malignancy decreased with patient's age. In patients older than 50 years proper image diagnosis to assess malignancy should be considered before orchiectomy is done.

Redefining our protocol of the orthognathic surgery-first approach after 10 years of experience.

The objective of this study was to update and redefine some concepts of the surgery-first (SF) approach, regarding its indications and contraindications, virtual planning work-up, surgical tips, and postoperative orthodontic benefits, after 10 years of experience. A retrospective analysis was made of orthognathic surgical procedures following the SF protocol between January 2010 and December 2019 to review inclusion and exclusion criteria, diagnostic workflow, surgical tips, and postoperative outcomes. A total of 148 SF procedures were performed during this period, which corresponded to only 9.2% of the total orthognathic surgeries performed, which means that we have broadened the exclusion criteria instead of reducing them. Surgical tips include interdental corticotomies solely in cases of anterior crowding and leaving the intermaxillary fixation miniscrews in place postoperatively for orthodontic skeletal anchorage. The mean duration of postoperative orthodontic treatment was reduced in comparison to conventional surgery (36.8 vs 87.5 weeks). The overall degree of satisfaction was high not only for the patients, but also for the orthodontists and surgeon. SF is especially indicated for patients who desire an immediate aesthetic result, with short-term orthodontics, or for treatment of sleep-related breathing disorders, if they meet the established criteria.

Carcinoma uretral primario: resultados de la experiencia de un único centro / Primary urethral carcinoma: Results from a single center experience

Introducción y objetivo El carcinoma primario de uretra (CPU) es una enfermedad neoplásica poco frecuente que surge en la uretra, sin evidencia de carcinoma previo o sincrónico en todo el tracto urinario. Dado que las enfermedades raras suelen diagnosticarse y tratarse de forma incorrecta, el objetivo de este estudio fue analizar la experiencia de un único centro urológico en el tratamiento del CPU, centrándose en las neoplasias que surgen de la uretra anterior masculina.Materiales y métodos Se revisaron retrospectivamente las historias clínicas de los pacientes con neoplasias a nivel de la uretra peneana y bulbar que se presentaron en nuestro centro terciario de referencia entre enero de 1988 y diciembre de 2018. Se excluyeron los pacientes con carcinoma de la uretra prostática. El diagnóstico se obtuvo con la ayuda de una uretroscopia y biopsia de la lesión. El estadio patológico local se evaluó mediante resonancia magnética nuclear (RMN) con contraste en pacientes seleccionados. El estadiaje se evaluó mediante examen clínico, ecografía y tomografía computarizada (TC). La cirugía radical (cistectomía radical + penectomía total + linfadenectomía inguinal bilateral) se propuso a los pacientes con tumores ≥ T2 o cN + con un buen estado funcional, tumor proximal y sin comorbilidades graves. En caso de afectación ganglionar, se ofreció adicionalmente quimioterapia neoadyuvante. Los pacientes con enfermedad localizada (< T2) y/o tumor más distal fueron sometidos a uretrectomía o penectomía parcial. Se evaluaron las curvas de Kaplan-Meier para el análisis de la supervivencia global (SG), la supervivencia cáncer específica (SCE) y la supervivencia libre de recidiva (SLR).Resultados Se estudiaron retrospectivamente un total de 13 pacientes varones con CPU anterior. Se realizó penectomía total en siete casos, mientras que cinco casos recibieron uretrectomía parcial y un caso, penectomía parcial. De los siete pacientes que se sometieron a una

Introduction and aim of the study Primary urethral carcinoma (PUC) is a rare neoplastic disease arising in the urethra, without any evidence of a previous or synchronous carcinoma of the entire urinary tract. Since rare diseases are often incorrectly diagnosed and managed, the aim of this study was to analyze the experience of a single urology center in the treatment of PUC, focusing on neoplasms arising from the male anterior urethra.Materials and methods Medical records of patients with neoplasms at the level of the penile and bulbar urethra who presented at our tertiary referral center between January 1988 and December 2018 were retrospectively reviewed. Patients with carcinoma of the prostatic urethra were excluded. The diagnosis was obtained with the aid of urethroscopy and lesion biopsy. Local staging was performed by means of contrast-enhanced MRI in selected patients. Staging was achieved by clinical examination, ultrasonography, and CT scan. Radical surgery (radical cystectomy + total penectomy + bilateral inguinal lymphadenectomy) was proposed to patients with ≥T2 tumors or cN + with a good performance status, proximal tumor and without severe comorbidities. In case of nodal involvement, neoadjuvant chemotherapy was additionally offered. Patients with localized disease (ResultsA total of 13 male patients with anterior PUC were studied retrospectively. Total penectomy was performed in 7 cases, while partial urethrectomy was performed in 5 cases, and partial penectomy in 1 case. Of the 7 patients who underwent total penectomy, 5 underwent radical cystectomy with bilateral inguinal lymphadenectomy. Three patients were treated with neoadjuvant systemic chemotherapy, of which 2 were cT3N + and

Temporomandibular joint arthrocentesis guided by ultrasonography: An anatomical study.

The temporomandibular joint (TMJ) arthrocentesis is a common procedure in maxillofacial surgery departments for the treatment of TMJ dysfunction. The use of ultrasonography in this area is rare, and in the vast majority of cases only as a diagnostic, and non-therapeutic use. Through this study we propose the equipment and ultrasound parameters necessary to obtain detailed and practical images when using ultrasonography as a therapeutic guide in arthrocentesis of TMJ. In addition, we provide data regarding the placement and working angulations of both the ultrasound probe and the needle that are ideal for facilitating image-guided puncture. It is a simple technique, with a relatively short learning curve, and that can provide considerable intraoperative help to the surgeon.

Whole and hemi-gland cryoablation for primary localized prostate cancer: Short and medium-term oncological and functional outcomes. / Crioablación total o hemiglandular para el cáncer de próstata primario localizado: resultados oncológicos y funcionales a corto y medio plazo.

INTRODUCTION: To compare oncological, functional and post-operative outcomes of hemi (HC) vs. whole gland (WGC) cryoablation as first line treatment of localized prostate cancer. MATERIAL AND METHOD: Sixty-six consecutive patients undertaking whole-gland cryoablation (WGC=40) or hemi-cryoablation (HC=26) in a tertiary referral centre between 2010 and 2018 were included. All patients had a low-intermediate risk prostate cancer according to D'Amico risk classification. Hemi-ablation was proposed in case of biopsy and prostate MRI proven unilateral prostate cancer. Primary endpoint was Cryotherapy Failure for which 3 definitions were considered and compared: 1) biochemical failure (> PSA nadir+≥ 2 ng/mL), 2) positive prostate re-biopsy with Gleason score ≥ 7, 3) initiation of further prostate cancer treatment. RESULTS: Median patients age at treatment was 74 [42-81] vs. 76 [71-80] years in WGC vs. HC group, respectively (p=.08). Low and intermediate D'Amico risk group were 15% and 85% vs. 23% and 77% (p=.75), respectively. Median follow- up time was 41 [1.5-99.0] vs. 27 [0.9-93] months (p=.03). Four-years cryotherapy failure free survival in WGC vs. HC were 69% vs. 53% with definition 1 (p=.24), 82% vs. 80% with definition 2 (p=.95), 83% vs. 77% with definition 3 (p=.73). Early and 1-year urinary continence were 60% and 83% in WGC vs. 72% and 83% in HC (p=.26). De novo impotency after cryotherapy was 75% vs. 46% (p=.33) in WGC vs. HC. CONCLUSIONS: In our cohort of highly selected patients with unilateral low/intermediate risk PCa, hemi-cryoablation may provide similar oncological outcomes and less early complications compared to whole-gland cryoablation.
