The role of androgen deprivation therapy prior to radical prostatectomy in high-risk prostate cancer: a systematic review.

INTRODUCTION: Patients with high-risk prostate cancer (HRPCa) are prone to have worse pathological features, resulting in early biochemical recurrence after radical prostatectomy (RP). There is an urgent need to develop novel treatment strategies for this group of patients to optimize their outcomes. The purpose of this study is to perform a systematic review of the role of neoadjuvant hormonal therapy (NHT) followed by RP in HRPCa patients. EVIDENCE ACQUISITION: We performed a systematic review of the following databases, MEDLINE (PubMed), EMBASE, Cochrane Library, and clinical Trial.gov; between January 2007 and August 2023, following the PRISMA guidelines. EVIDENCE SYNTHESIS: After screening and deduplication, we included ten studies from an initial pool of 1275. The risk of bias was low in observational studies but ranged from moderate to low in controlled trials. Five studies utilized traditional androgen deprivation treatments (ADT), revealing favorable pathological outcomes but inconsistency in evaluating oncological results. Additionally, four studies focused on RP combined with androgen receptor pathway inhibitors (ARPIs) in the NHT setting, all showing primarily positive pathological outcome, with no clear evidence of an oncological benefit. Limited long-term follow-up data and a shortage of randomized controlled trials were evident among all the studies included in this review, regardless of the type of hormonal treatment used. CONCLUSIONS: Different hormonal treatments, including traditional ADT and ARPIs, yield positive pathology outcomes. Oncological evidence remains limited, echoing older findings predating ARPIs. Definitive conclusions require longer follow-ups and precise patient selection. Currently, insufficient evidence support ARPIs' superiority over conventional therapy before RP.

External validation of an algorithm to personalize nerve sparing approaches during robot-assisted radical prostatectomy in men with unilateral high-risk prostate cancer.

Limited evidence exists about preserving neurovascular bundles during radical prostatectomy (RP) for high-risk prostate cancer (HRPCa) patients. Hence, we validated an existing algorithm predicting contralateral extraprostatic extension (cEPE) risk in unilateral high-risk cases. This algorithm aims to assist in determining the suitability of unilateral nerve-sparing RP. Among 264 patients, 48 (18%) had cEPE. The risk of cECE varied: 8%, 17.2%, and 30.8% for the low, intermediate, and high-risk groups, respectively. Despite a higher risk of cECE among individuals classified as low-risk in the development group compared to the validation group, our algorithm's superiority over always/never nerve-sparing RP was reaffirmed by decision curve analysis. Therefore, we conclude that bilateral excision may not always be justified in men with unilateral HRPCa. Instead, decisions can be based on our suggested nomogram.

Humoral complementomics - exploration of noninvasive complement biomarkers as predictors of renal cancer progression.

Despite the progress of anti-cancer treatment, the prognosis of many patients with solid tumors is still dismal. Reliable noninvasive biomarkers are needed to predict patient survival and therapy response. Here, we propose a Humoral Complementomics approach: a work-up of assays to comprehensively evaluate complement proteins, activation fragments, and autoantibodies targeting complement proteins in plasma, which we correlated with the intratumoral complement activation, and/or local production, focusing on localized and metastatic clear cell renal cell carcinoma (ccRCC). In two prospective ccRCC cohorts, plasma C2, C5, Factor D and properdin were elevated compared to healthy controls, reflecting an inflammatory phenotype that correlated with plasma calprotectin levels but did not associate with CRP or with patient prognosis. Conversely, autoantibodies against the complement C3 and the reduced form of FH (a tumor neo-epitope reported in lung cancer) correlated with a favorable outcome. Our findings pointed to a specific group of patients with elevated plasma C4d and C1s-C1INH complexes, indicating the initiation of the classical pathway, along with elevated Ba and Bb, indicating alternative pathway activation. Boostrapped Lasso regularized Cox regression revealed that the most predictive complement biomarkers were elevated plasma C4d and Bb levels at the time of surgery, which correlated with poor prognosis. In conclusion, we propose Humoral Complementomics as an unbiased approach to study the global state of the complement system in any pathological plasma sample and disease context. Its implementation for ccRCC revealed that elevated C4d and Bb in plasma are promising prognostic biomarkers, correlating with shorter progression-free survival.

An updated model for predicting side-specific extraprostatic extension in the era of MRI-targeted biopsy.

PURPOSE: Accurate prediction of extraprostatic extension (EPE) is pivotal for surgical planning. Herein, we aimed to provide an updated model for predicting EPE among patients diagnosed with MRI-targeted biopsy. MATERIALS AND METHODS: We analyzed a multi-institutional dataset of men with clinically localized prostate cancer diagnosed by MRI-targeted biopsy and subsequently underwent prostatectomy. To develop a side-specific predictive model, we considered the prostatic lobes separately. A multivariable logistic regression analysis was fitted to predict side-specific EPE. The decision curve analysis was used to evaluate the net clinical benefit. Finally, a regression tree was employed to identify three risk categories to assist urologists in selecting candidates for nerve-sparing, incremental nerve sparing and non-nerve-sparing surgery. RESULTS: Overall, data from 3169 hemi-prostates were considered, after the exclusion of prostatic lobes with no biopsy-documented tumor. EPE was present on final pathology in 1,094 (34%) cases. Among these, MRI was able to predict EPE correctly in 568 (52%) cases. A model including PSA, maximum diameter of the index lesion, presence of EPE on MRI, highest ISUP grade in the ipsilateral hemi-prostate, and percentage of positive cores in the ipsilateral hemi-prostate achieved an AUC of 81% after internal validation. Overall, 566, 577, and 2,026 observations fell in the low-, intermediate- and high-risk groups for EPE, as identified by the regression tree. The EPE rate across the groups was: 5.1%, 14.9%, and 48% for the low-, intermediate- and high-risk group, respectively. CONCLUSION: In this study we present an update of the first side-specific MRI-based nomogram for the prediction of extraprostatic extension together with updated risk categories to help clinicians in deciding on the best approach to nerve-preservation.

The extrusion of a penile prosthesis is an indicator of infection and implies its removal, causing fibrosis and shortening of the penis.We present a 62-year-old man, to whom we implanted a hydraulic prosthesis, and three weeks later we underwent salvage surgery by extrusion of the activation pump. After removing the prosthesis, we wash the cavities with four dilutions. The 1st to 50% of hydrogen peroxide; the 2nd to 50% of povidone iodine; the 3rd with 1 g of cefazolin and 40 mg of tobramycin, the 4th with 80 mg of gentamicin and 500 mg of vancomycin. In the act we implanted a malleable prosthesis bathed in antibiotic solutions.The postoperative period was satisfactory. A year later, the patient presents an adequate penile length and aesthetic appearance, maintaining satisfactory sexual relations.Surgical rescue by washing with antiseptic solutions and a malleable prosthesis implant, minimizes the risk of reinfection, preserving sexual function.

Seguimiento a largo plazo de la incurvación peneana congénita tratada mediante rotación de los cuerpos cavernosos / Long term results of congenital penile curvature treated with cavernosa corpora rotation

INTRODUCCIÓN: La incurvación peneana congénita (IPC) es un trastorno originado por una alteración en el desarrollo embrionario de la uretra y los cuerpos cavernosos, que condiciona dificultad para la penetración, precisando corrección quirúrgica cuando imposibilita el coito. OBJETIVO: Analizar los resultados del tratamiento quirúrgico de la IPC mediante rotación de los cuerpos cavernosos (RCC) descrita y modificada por Shaeer. PACIENTES Y MÉTODOS: Diez pacientes diagnosticados de IPC con imposibilidad para el coito, fueron intervenidos en un período de 36 meses. Previo a la intervención aplicamos el cuestionario IIEF-5, medimos la longitud del pene y el ángulo de incurvación mediante autofotografías en tres proyecciones. Mediante abordaje subcoronal realizamos el denudamiento del pene. A ambos lados de la uretra incidimos la fascia de Buck y liberamos el paquete vasculonervioso desde la cara ventral hasta dorsal. Generamos una erección artificial evidenciando la incurvación. En la cara dorsal deambos cuerpos cavernosos realizamos dos incisiones longitudinales en la capa longitudinal externa de la túnica albugínea. Suturamos los bordes internos y externosde ambas incisiones entre sí con una sutura continuade monofilamento irreabsorbible de 4/0, comprobando mediante una erección artificial la corrección de la incurvación. Los pacientes fueron dados de alta al día siguiente de la intervención. Al sexto mes se determinaron la longitud e incurvación peneanas, y el cuestionario IIEF-5. Para la comparación de medias utilizamos el test de la U de Mann-Whitney. RESULTADOS: La edad media fue 26,8 años. El seguimiento promedio fue 20,7 meses (12-31) y la mediana 24. Antes de la intervención la incurvación media fue 68,5° (50-90°); la longitud media 14,2 cm (10-18) yel IIEF-5 de 21. Tras la intervención la longitud media fue 13,7 cm, la incurvación residual 25. No existieron diferencias estadísticamente significativas entre la longitud peneana pre y postquirúrgica, (p = 0,08). Nueve pacientes aseguraron que volverían asometerse a la misma intervención. CONCLUSIONES: La RCC constituye una alternativa terapéutica eficaz a las técnicas de plicatura o alargamiento de la túnica albugínea para el tratamiento de la IPC, manteniendo sus resultados a largo plazo

INTRODUCTION: Congenital penile curvature (PCC) is a disorder caused by an alteration in the embryonic development of the urethra and the corporacavernosa, which causes difficulty in penetration, requiring surgical correction when inter course is impossible. OBJECTIVE: To analyze the results of the surgical treatment of the IPC by means of rotation of the corpora cavernosa (RCC) described and modified by Shaeer. PATIENTS AND METHODS: Ten patients diagnosed with PCC with impossibility to inter course, were operated in a period of 36 months. Prior to the intervention,we applied the IIEF-5 questionnaire, measured the length of the penis and the angle of curvature throughself-photographs in three projections. By subcoronal approach,we perform denudation of the penis. On both sides of the urethra we incised Buck’s fascia and released the neurovascular bundle from the ventral to the dorsal side. We generate an artificial erection evidencing the curvature. On the dorsal aspect of both corpora cavernosa, we made two incisions in the external longitudinal layer of the tunica albuginea. We sutured the internal and external edges of both incisions together with a 4/0 non-reabsorbable monofilament continuous suture, checking the correction of the curvature by means of an artificial erection. The patients were discharged the day after the intervention. The penile length and curvature were determined in the sixth month, and the IIEF-5 questionnaire. For the comparison of means we used the Mann-Whitney U test. RESULTS: The mean age was 26.8 years. The average follow-up was 20.7 months (12-31) and the median was 24. Before the intervention, the average curvature was 68.5° (50-90°); the average length 14.2 cm (10-18) and the IIEF-5 of 21. After surgery, the average length was 13.7 cm, the residual curvature the IIEF-5 of 25. There were no statistically significant differences between pre and postoperative penile length, (p = 0.08). Nine patients assured that they would under go the same intervention again. CONCLUSIONS: RCC is an effective therapeutic alternative to the techniques of plication or lengthening of the tunica albuginea for the treatment of PCC, main tainingits long-term results
