Advances in urologic oncology "OncoUrology Forum Special Edition": The best of 2020.

OBJECTIVE: To provide latest findings of Urologic Oncology on prostate, kidney, and bladder cancer, and analyze its impact on clinical practice as well as future schemes in the medium- and long-term. METHODS: This document reviews the abstracts on Uro-Oncology presented at the 2020 Congresses (EUA, AUA, ASCO, ESMO and ASTRO), the publications with the highest impact and especially the new lines of development and progress in Uro-Oncology evaluated by the OncoForum committee. RESULTS: The use of prostate-specific membrane antigen (PSMA) radioligands in the diagnosis of prostate cancer may have great potential and utility in the coming years due to their improved sensitivity and specificity. The genetic characterization of the tumor is important at both, germline and somatic levels, due to the significant role of BRCA2 mutations regarding risk. The cohort multiple randomised controlled trial is the most suitable study design at the genitourinary cancer level. The application of big data will lead to process improvements, savings in healthcare costs, and an empowerment of real-life studies through ease of data comparison, management, and storage. CONCLUSIONS: The use of new diagnostic techniques with PSMA ligands will provide a more comprehensive diagnostic modality, increase the number of studies about tumor genetic profiling, and enhance their quality. The practical application of artificial intelligence will improve the treatment genitourinary cancer.

Consequences of penile fracture: Complications and long-term functional outcomes.

INTRODUCTION: Penile fracture (PF) is a urological emergency with low incidence, and evidence of its long-term outcomes is scarce. This study focuses on postoperative complications and long-term functional outcomes in patients with PF and surgical repair at our center. MATERIALS AND METHOD: Clinical records of patients undergoing urgent surgery for PF at a third level hospital between 2006 and 2020 were retrospectively reviewed. Functional outcomes were assessed with voluntary telephone interviews from June 2020 to February 2021. Lower urinary tract symptoms were screened by IPSS questionnaire, sexual function by EHS and IIEF-5 and morphological alterations by direct questions to patients. RESULTS: A total of 41 patients underwent surgery for PF. Eleven of them also had urethral injury (higher incidence if there was bilateral corpora cavernosa injury, 19.4% vs. 80%, p < 0.05). Only 1 patient presented a Clavien-Dindo type 3a complication due to wound dehiscence, 4 (13%) type 2 and 9 (29%) type 1. Twenty-four patients underwent long-term follow-up, of whom 20 (83.3%) presented normal sexual function. Twelve patients (50%) had a palpable nodule at the fracture site, 8 (33.3%) had new onset penile curvature and 1 patient with previous urethral injury presented urethral stricture. CONCLUSION: In cases of penile fracture, there is a higher incidence of urethral injury if both corpora cavernosa are affected. Long-term functional sequelae after surgical repair of a PF are rare.

Non-metastatic castration-resistant prostate cancer: management recommendations.

INTRODUCTION AND OBJECTIVE: Survival and quality of life (QoL) of patients with non-metastatic castration-resistant prostate cancer (nmCRPC) deteriorate significantly when they develop metastases. New generation antiandrogens (apalutamide, enzalutamide and darolutamide) can prolong metastasis-free survival (MFS) and overall survival (OS) in these patients, maintaining their QoL. MATERIAL AND METHODS: After the performance of a systematic review of the literature, a scientific committee reached a consensus on simple and practical recommendations to consolidate and improve the management of patients with nmCRPC in urology consultations. RESULTS: Recommendations are made on the frequency of PSA determination and imaging tests in patients with nmCRPC. The importance of co-morbidities in patients with nmCRPC is also highlighted, and recommendations are also made on functional and QoL assessment that can be carried out during urology consultations. The efficacy, safety, and effects on QoL of new generation antiandrogens are reviewed. CONCLUSIONS: To evaluate treatment of patients with nmCRPC, it is necessary to consider co-morbidities and QoL, in addition to age. New generation antiandrogens are a safe and effective treatment option for patients with nmCRPC. The recommendations of this review can be helpful in optimizing the management of nmCRPC patients in urology consultations.

Efficacy and safety of collagenase Clostridium histolyticum in Peyronie's disease following a modified treatment protocol. / Eficacia y seguridad de la colagenasa de Clostridium histolyticum en la enfermedad de Peyronie según un protocolo de tratamiento modificado.

INTRODUCTION: Collagenase Clostridium histolyticum (CCH) is the only approved treatment for conservative management of Peyronie's disease (PD) that has demonstrated efficacy and safety in clinical trials. However, as the standard treatment protocol is time and resource consuming, we are introducing a new CCH treatment protocol with a more cost-effective profile. Our goal is to evaluate its efficacy and safety. MATERIALS AND METHODS: We included patients with PD in stable phase, with curvatures of 30-90degrees. Ventral curvatures and complex deformities were excluded. The treatment protocol consists of a full dose of CCH injected along the PD plaque, forming two lines of four injections. Patients were educated in daily penile modeling activities. The need for a new treatment cycle, up to a maximum of 8 cycles or until the 30-degree curve was decreased, was reevaluated every 4weeks. Changes in curvature and number of cycles were recorded to evaluate the efficacy. Regarding safety evaluation, treatment-related adverse events (TRAEs) were recorded, including rupture of the corpora cavernosa, penile hematoma, hematuria, and local infection. RESULTS: Thirty-one patients were treated under the modified protocol. The mean initial curvature was of 49.84 (±15.83) degrees. Curvature improvement was recorded in 25 patients (80.6%), with a mean absolute reduction of 20.65 (±15.42) degrees and relative reduction of 44%. The mean curvature after treatment was 30.67 (±17.25) degrees. Most patients required one (19.4%) or two (54.8%) injections. No patient presented TRAEs. CONCLUSIONS: The results suggest that the modified CCH treatment protocol is effective and safe, but more studies should be carried out to optimize the current standard protocol.

Advances in urologic oncology "OncoForum": The best of 2019. / Avances en uro-oncología «OncoForum¼: lo mejor del 2019.

OBJECTIVE: Review the latest evidence on urologic oncology on kidney, bladder and prostate tumors. METHODS: Abstracts on kidney, bladder and prostate cancer presented at the 2019 congresses (EAU, AUA, ASCO and ESMO) and the publications with the greatest impact in this period, with the highest evaluation by the OncoForum committee, are reviewed. RESULTS: In patients with metastatic kidney cancer, regimens including immunotherapy (nivolumab + ipilimumab, pembrolizumab) have been shown to be superior to sunitinib in terms of survival. In patients with non-muscle invasive bladder cancer, pembrolizumab has been shown to be an effective alternative in those refractory to bacillus Calmette-Guérin, while in patients with metastatic urothelial cancer, third-line enfortumab vedotin achieved a significant response rate (44%). In patients with localized prostate cancer (PCa), ultrafractionated external radiotherapy did not show any greater acute toxicity than fractionated or hypofractionated radiotherapy. The benefit of enzalutamide and apalutamide associated with castration has been confirmed in M1 PCa patients, regardless of disease volume. In patients with castration-resistant M0 PCa, treatment with enzalutamide, apalutamide or darolutamide has been associated with a delay in the occurrence of metastasis and prolonged survival. Cabazitaxel has demonstrated a survival benefit in patients with metastatic CRPC, while olaparib showed anti-tumor activity after chemotherapy in those tumors with mutations in DNA repair genes. CONCLUSIONS: These data show the implementation of immunotherapy as a novel alternative against renal and bladder cancer. The arrival of new agents for advanced urothelial carcinoma should be highlighted, and the efficacy of enzalutamide and apalutamide in de novo metastatic prostate cancer is established. In metastatic CRPC, cabazitaxel and olaparib (targeting mutations) are promising therapeutic options.

[Cell energetic loading in experimental renal transplant with different periods of warm ischemia]. / Estudio de la carga energética celular en el trasplante renal experimental con diferentes periodos de isquemia caliente (0-30-45 y 90').

INTRODUCTION AND GOALS: Renal procurement after a period of heart st op demands a previous knowledge of ischemia-reperfusion injuries means. To study cell injury mechanisms an experimental study has been designed in pigs, with different rangres of warm ischemia (0-30-45 and 90 min). The main goal was to research on the basis of ischemic injury. MATERIAL AND METHODS: Biochemical parameters (creatinine, urine output), energetic loading (ATP, ADP, AMP and global energetic loading) and pathological studies as long as survival analysis by 5th day were completed. RESULTS: Animal survival and graft viability range from 100% at 5th day in control and 30 min warm ischemia groups to 60% in 90 min warm ischemia group. Creatinine levels rises at 1st, 3rd and 5th day, especially in those non-viable organs. ATP levels decrease after warm ischemia period, increases ADP and AMP levels after reperfusion in those viable organs. CONCLUSIONS: Prolonged periods of warm ischemia do not result necessarily in non-viable kidneys. Viable organs recover nucleotide levels early. Study of energetic cell loading levels is a good way to get on better in the knowledge of injury mechanisms after ischemia-reperfusion.

We perform a brief discussion of surgery indications of surgery in these patients.

Developments in urologic oncology "OncoForum": The best of 2017. / Avances en uro-oncología «OncoForum¼: lo mejor del 2017.

OBJECTIVE: To put forth new findings of urologic oncology with impact on clinical practice presented during 2017 in the main annual meetings. METHODS: This document reviews abstracts on prostate, kidney and bladder cancer presented at the congresses of 2016 (EAU, AUA, ASCO, ESMO and ASTRO) and publications with the highest impact in this period valued with the highest scores by the OncoForum committee. RESULTS: Among patients at high risk of recurrent renal cell carcinoma after nephrectomy, adjuvant sunitinib compared to placebo showed a benefit in patients at higher risk of recurrence. In cisplatin-ineligible advanced urothelial cancer, pembrolizumab elicits clinically meaningful, durable responses. Among patients with localized prostate cancer, treatment for disease progression was less frequent (absolute difference, 26.2 percentage pontis) and adverse events was more frequent with surgery than with observation. Among patients with locally advanced or merastatic prostate cancer, androgen-deprivation therapy plus abiraterone and prednisolone resulted in fewer deaths and fewer treatment-failure events (P<.001). Among patients with metastatic castration-resistant prostate cancer previously treated with abiraterone acetate, enzalutamide median radiographic progression free survival was 8,1 months and enzalutamide median overall survival was not reached. CONCLUSIONS: Among patients at high risk of recurrent renal cell carcinoma after nephrectomy, adjuvant sunitinib showed a benefit across subgroups including patients at higher risk of recurrence. Among patients with localized prostate cancer, surgery was not associated with significantly lower all-cause or porstate-cancer mortality than observation. Among patients with locally advanced or merastatic prostate cancer, androgen-deprivation therapy plus abiraterone and prednisolone was associated with significantly higher rates of overall and failure-free survival than androgen-deprivation therapy alone. In patients with metastatic castration-resistant prostate cancer previously treated with abiraterone enzalutamide remained active.

Developments in urologic oncology «OncoForum¼: The best of 2016. / Avances en uroncología «OncoForum¼: lo mejor de 2016.

OBJECTIVE: To put forth new findings of urologic oncology with impact on clinical practice presented during 2016 in the main annual meetings. ACQUISITION OF EVIDENCE: This document reviews abstracts on prostate, kidney and bladder cancer presented at the congresses of 2016 (EAU, AUA, ASCO, ESMO and ASTRO) and publications with the highest impact in this period valued with the highest scores by the OncoForum committee. SYNTHESIS OF EVIDENCE: In High-Risk Renal-Cell carcinoma after nephrectomy, disease-free survival was significantly greater for sunitinib than placebo group, with adverse events more frequents. In locally advanced and metastatic urotherial carcinoma patients, aletozumab achieved overall response rate in all subgroups of patients, included poor prognostic. In localized prostate cancer, the difference of prostate-cancer-specific mortality among active monitoring, radical prostatectomy and external-beam radiotherapy was not significant (P=0,48). In TERRAIN study, with castration-resistant prostate cancer patients, adverse events was reported in 31% and 23% of patients treated with enzalutamide and bicalutamide, respectively. Moreover, enzalutamide significantly improved median progression-free survival (15.7 months) compared bicalutamide (5.8 months) (P<.0001). In SRTIVE study, Enzalutamide reduced the risk of progression or death by 76% compared with bicalutamide (P<.001). CONCLUSIONS: In high-risk renal-cell carcinoma after nephrectomy, sunitinb has been considered as treatment choice. In localized prostate cancer, prostate-cancer-specific mortality was low irrespective of the treatment assigned (active monitoring, radical prostatectomy and external-beam radiotherapy). In metastatic castration-resistant prostate cancer new results of treatment with enzalutamide and abiraterone has been published, wich have been shown beneficial effects in metastatic and no metastatic patients.

Developments in urologic oncology «OncoForum¼: The best of 2015. / Avances en uro-oncología «OncoForum¼: lo mejor de 2015.

OBJECTIVE: To review the latest evidence on the oncologic urology of prostate, renal and bladder tumours, analysing their impact on daily clinical practice and future medium to long-term regimens. METHODS: We review the abstracts on prostate, renal and bladder cancer presented at the 2015 congresses (EAU, AUA, ASCO, ESMO y ASTRO) that received the best evaluations by the OncoForum committee. RESULTS: Cabozantinib could represent a new second-line (or subsequent) treatment option for patients with advanced renal cancer. In muscle-invasive bladder cancer, the genetic expression profile could predict the clinical benefit of neoadjuvant therapy in treating urothelial tumours. In metastatic castration-resistant prostate cancer, results were presented from various studies that evaluated the addition of chemotherapy to standard treatment with androgen deprivation, showing a reduction in the progression risk and higher PSA response rates. CONCLUSIONS: New options for the second-line treatment of renal cancer were presented. In metastatic castration-resistant prostate cancer, various studies have been published on treatment with enzalutamide, which has been shown to delay the symptomatic disease and benefit overall survival.

Developments in urologic oncology 'OncoForum': The best of 2014.

OBJECTIVE: To review the latest evidence on the oncologic urology of prostate, renal and bladder tumors, analyzing their impact on daily clinical practice and the future medium to long-term regimens. METHODS: We review the abstracts on prostate, renal and bladder cancer presented at the 2014 congresses (European Association of Urology, American Urological Association, American Society of Clinical Oncology and American Society for Radiation Oncology) that received the best evaluations by the OncoForum committee. RESULTS: The committee considered the following messages important: cytoreductive nephrectomy followed by treatment with a tyrosine-kinase inhibitor can significantly increase the overall survival of patients with metastatic renal cancer; for advanced bladder cancer, early adjuvant chemotherapy after cystectomy is preferable because it significantly increases progression-free survival; and several studies have shown that multiparametric magnetic resonance imaging and fusion imaging improve the diagnosis of prostate cancer and provide greater possibilities for placing patients in the appropriate risk group in order to offer them the best treatment possible. The results of the PREVAIL study have demonstrated the efficacy of enzalutamide on the overall survival of men with castration-resistant prostate cancer and metastases, with no prior chemotherapy. The study also demonstrated the drug's favorable safety profile. CONCLUSIONS: Progress is continuing in renal and bladder cancer, improving the approach and clinical results with current therapeutic options. There is constant progress in castration-resistant prostate cancer; in 2014, prechemotherapy treatments were consolidated.

Does the Pulsatile Preservation Machine Have Any Impact in the Discard Rate of Kidneys From Older Donors After Brain Death?

BACKGROUND: Donors after brain death (DBD) older than 60 years have become 46.8% of our current activity, with higher risk of renal discard rate (RDR). Assessment of kidney suitability requires complementary strategies: macroscopic evaluation, kidney biopsy score (KBS), and renal hemodynamic evaluation with the Pulsatile Perfusion Machine (PPM). METHODS: Descriptive, cross-sectional, comparative study of kidneys procured and RDR, comparing 3 time periods: 2000 to June 2004, when only KBS were used; July 2004 to 2008 (introduction of PPM and learning period); and 2009 to 2013 (experienced use of PPM). Transplantation criteria were KBS <3 and PPM renal resistance <0.4 mm Hg/mL/min and arterial renal flow >70 mL/min. RESULTS: Between 2000 and 2013, a 59.2% reduction in DBD kidneys was observed. However, older kidneys had an increase from 33.5% to 46.8%. The RDR had increased, comparing the first to the third period from 25.4% to 38.3%. However, the RDR was lower when kidneys were evaluated with PPM than those evaluated only with KBS and preserved in cold storage (CS) (21.4% versus 43.7%). There was a significant difference in cold ischemia time, because CS kidney was grafted before PPM. During the third period, more kidneys with KBS ≥4 were assigned to PPM. CONCLUSIONS: Notwithstanding the decrease in DBD-procured kidneys and the increase in older kidneys during last period, the use of PPM allowed low DR compared with CS. A bias in the results of PPM could be generated when kidneys with higher KBS were excluded from PPM. The use of KBS only to decide acceptance could preclude the use of an additional tool to evaluate suitability.

[Expression of the tumor suppressor gene p53 in superficial transitional carcinoma of the bladder]. / Expresión del gen supresor tumoral p53 en los carcinomas transicionales superficiales de vejiga.

Presentation of 113 cases of transitional cells surface tumours of the bladder where p53 protein expression has been used and compared to known prognostic factors. The existence of a statistically significant relationship between this expression and the tumoral grade and stage in all studied groups has been noticed. It can be concluded that the expression of this protein can be useful as a new prognostic factor, even though it is still necessary to conduct more studies, basically prospective.

[Relationship between tumor recurrence and the expression of the p53 gene in primary superficial transitional carcinoma of the bladder]. / Relación entre las recidivas tumorales y la expresión del gen p53 en los carcinomas transicionales superficiales primarios de vejiga.

Contribution of 60 patients with primary surface transitional cell tumours of the bladder where nuclear expression of p53 protein was prospectively studied and compared to known prognostic factors in an attempt to find out its role in the development of relapses. An statistically significant relationship was found between the protein expression and cytology, tumoral multifocality, stage, relapse development and tumoral progression. It can be concluded that expression of this protein can be of use as relapse predictor.

[Cystolysis. Supratrigonal denervation]. / Cistolisis. Denervación supratrigonal.

CI is an entity with obscure etiopathogenesis and difficult to manage. This essay contributes three cases, out of a series of 25, were cytolisis was performed. Results after six months follow-up are very encouraging, since pain has disappeared in all cases and pollakiuria has been radically reduced.

[High incidence of chromosome 8 monosomy and chromosome 7 trisomy in prostatic primary tumor and its related lymphatic metastasis. Preliminary results]. / Alta incidencia de la monosomia del cromosoma 8 y la trisomia del cromosoma 7 en el tumor primario prostático y su metástasis ganglionar asociada. Resultados preliminares.

INTRODUCTION: The research on tumoral aggressivity parameters in prostate cancer, such DNA ploidy detected by fluorescence in situ hybridization, has significant relevance to refine prognostic on an individualized patient. OBJECTIVES: To identify chromosome numeric alterations by FISH in primary prostate cancer focus and its corresponding lymph node metastases. b) To describe a cytogenetic tumoral progression pathway. METHODS: So far, we have retrospectively studies eight patients with prostate cancer and lymph node metastases performing FISH analysis on the primary prostate cancer focus and its metastatic lymph node. DNA probes for chromosomes 7, 8, 10 and 12 have been used for FISH analysis. RESULTS: a) Seven out of eight tumours (85%) were aneuploid when studied by FISH and the most frequent chromosome alterations found were monosomy 8 (100%) and trisomy 7 (85.7%). All the lymph nodes were aneuploid being monosomy 8 (87.5%) and trisomy 7 (62.5%) the most common chromosome alterations. b) Monosomy 8 and trisomy 7 appeared to be in the same cytogenetic tumoral progression pathway. CONCLUSION: Although we report about a preliminary study, monosomy of chromosome 8 and trisomy 7 are related with poor evolution, probably because of the loss of a suppressor gene or a proto-oncogen overexpression. The presence of any of them in a prostate cancer focus is related with poor prognosis.

Advances in uro-oncology "OncoForum": the best of 2013.

OBJECTIVE: To present the new findings in oncologic urology with impact on clinical practice which were displayed at 2013 major annual meetings (EAU, ESTRO, AUA, ASCO and ASTRO). METHODS: The abstracts on prostate kidney, bladder and upper tract urothelial cancer with the highest scores by the OncoForum committee, presented in 1013 Congresses are included in this paper. RESULTS: the following messages were considered as important by the OncoUrology Forum committee. In renal tumors T1a, comorbidities should be evaluated by its impact on overall and specific cancer survival, especially in men over 65. In metastatic renal tumors, the benefit of Everolimus vs. Sunitinib has not been demonstrated. Patients with non-muscle invasive bladder cancer of high risk, with three or more risk factors, should be considered for radical cystectomy. The ERSPC study' data demonstrate the benefit of the systematic screening in prostate cancer. In metastatic disease, the results of the Ra-223 and enzalutamide studies show benefit in pain control and overall survival in metastatic disease. CONCLUSIONS: Localized renal and non-muscle invasive bladder of high-risk tumors, should be assessed according to comorbidities or oncologic risk factors, to determinate the adequate treatment options. New data from metastatic prostate cancer clinical trials have shown promising results in the control of the disease.
