RESUMEN
Localized renal cell carcinoma (RCC) has the potential to be cured with surgery alone; however, some patients have a high risk of relapse and may benefit from additional treatment. Several efforts have been made to identify effective strategies, with mostly negative results. However, recent results with immune checkpoint inhibitors may change the current standard, and several ongoing trials are exploring new alternatives. In this perspective, we aim to provide an overview of previous adjuvant therapy efforts, current data supporting the use of checkpoint blockade, and a future outlook for adjuvant therapy in renal cell carcinoma.
RESUMEN
Prostate cancer (PCa) is one of the most frequent causes of cancer death worldwide. Historically, diagnosis was based on physical examination, transrectal (TRUS) images, and TRUS biopsy resulting in overdiagnosis and overtreatment. Recently magnetic resonance imaging (MRI) has been identified as an evolving tool in terms of diagnosis, staging, treatment decision, and follow-up. In this review we provide the key studies and concepts of MRI as a promising tool in the diagnosis and management of prostate cancer in the general population and in challenging scenarios, such as anteriorly located lesions, enlarged prostates determining extracapsular extension and seminal vesicle invasion, and prior negative biopsy and the future role of MRI in association with artificial intelligence (AI).
RESUMEN
Immunotherapy, in the form of immune checkpoint inhibitors (ICI), has shown activity in metastatic urothelial bladder carcinoma, resulting in the approval of several ICI agents in the first- and second-line settings. This has led to an increased interest in studying their efficacy in the neoadjuvant setting for muscle invasive disease - an area of significant unmet need. This non-systematic review will look at the evidence supporting the use of ICI in the neoadjuvant setting for this tumor, results of early-phase studies, ongoing trials, and possible future applications for these drugs.
RESUMEN
PURPOSE OF REVIEW: The purpose of this review is to summarize the most current literature regarding the most important aspects to consider when developing a center of excellence for prostate imaging and biopsy. RECENT FINDINGS: Multiparametric MRI (mp-MRI) has changed the way we diagnose and treat prostate cancer. This imaging modality allows for more precise identification of areas suspicious in terms of harboring prostate cancer, enabling performance of targeted mp-MRI-guided biopsies that have been demonstrated to yield superior cancer detection rates. Centers worldwide are increasingly adopting this technology. However, obtaining results comparable with those findings published in the literature can be challenging. The imaging and biopsy process entails the need for a multidisciplinary team including a dedicated radiologist, urologist, and pathologist. Adequate mp-MRI interpretation for accurate lesion identification, acquaintance with the biopsy technique selected, and precise characterization of Gleason Score/Grade Groupings are equal determinants of accurate biopsy results. Furthermore, all specialists are required to attain appropriate learning curves to ensure optimal results. In this review, we characterize crucial aspects to consider when developing a center of excellence for prostate imaging and biopsy as well as insights regarding how to implement them.

INTRODUCCIÓN: El cáncer de próstata (PC) es una enfermedad de alta incidencia y prevalencia (90/100.00 habitantes) y constituye la segunda causa por muerte oncológica en hombres, fenómeno que acontece en su fase metastásica (mPC). El tratamiento estándar en esta etapa corresponde a la terapia de deprivación androgénica (TDA) que produce una respuesta oncológica favorable en términos de descenso del PSA y estabilización y/o regresión de las metástasis. Ésta primera etapa (castración sensible) dura en promedio 2 a 3 años, tras lo cual ocurre una independización tumoral del estímulo androgénico, fenómeno conocido como castración-resistencia (mCRPC). En esta etapa la quimioterapia (QMT) con docetaxel prolonga la sobrevida aproximadamente 4 meses, lo cual en conjunto con otros tratamientos de segunda línea (abiraterona, enzalutamida, etc.) logra alcanzar una sobrevida media desde el diagnostico de mCRPC de 24 meses. Diversos estudios (CHAARTED y STAMPEDE) han demostrado que el inicio de docetaxel junto con TDA en pacientes con mPC castración-sensible (mCSPC) prolongan sobrevida global hasta 17 meses, especialmente si hay alto volumen de enfermedad. El objetivo del estudio es describir las características clínicas, la respuesta oncológica inicial y el perfil de efectos adversos de pacientes con mCSPC sometidos a docetaxel. MATERIALES Y MÉTODOS: Estudio retrospectivo descriptivo entre mayo 2014 a Julio 2017. Se incluyeron pacientes ng/ml (rango 10,8 - 5550) y mediana de seguimiento 6 meses (rango 3 20). Catorce pacientes tenían Gleason > 8, 18 eran M+ de los cuales 9 eran viscerales. Solo uno recibió tratamiento local previo. La mediana de inicio de QMT fue 3,1 (0 6,1) meses post inicio TDA.Dieciséis pacientes completaron docetaxel y 4 siguen en curso. No hubo suspensión de QMT por efectos adversos. Los más frecuentes fueron diarrea (8/20), neuropatía (5/20) y vómitos (2/20). La mayoría fue grado 1 y solo tres presentaron complicaciones grado 3 (diarrea, leucopenia y trombocitopenia). No hubo complicaciones grado 4 -5. Diez pacientes alcanzaron un antígeno < 2 ng/ml a las 12 semanas post tratamiento y 7 presentaron recidiva bioquímica durante el seguimiento. Uno tuvo respuesta imagenológica completa, 10 respuesta parcial, 7 estabilidad y 2 mostraron progresión. CONCLUSIONES: El uso de Docetaxel en mCSPC es seguro, presenta escasos efectos adversos (la mayoría de intensidad leve) que no motivan suspensión. El tratamiento con docetaxel exhibe una respuesta prometedora en términos de control de PSA, sin embargo se requiere mayor seguimiento de esta cohorte para evaluar impacto en sobrevida. con mCSPC con enfermedad de alto volumen (metástasis óseas extra-axiales, viscerales o Gleason 9-10) y ECOG 0-1. Los pacientes recibieron TDA y seis ciclos de Docetaxel. Se registraron datos demográficos, clínicos, histopatológicos, PSA, imagenológicos (RECIST V1.1) y toxicidad (NCI CAE 4.0) RESULTADOS: Se incluyeron 20 pacientes, mediana de edad 63 años (rango 49 75). Mediana PSA de ingreso 267,5 ng/ml (rango 10,8 - 5550) y mediana de seguimiento 6 meses (rango 3 20). Catorce pacientes tenían Gleason > 8, 18 eran M+ de los cuales 9 eran viscerales.

INTRODUCTION: Prostate cancer is a disease with high incidence and prevalence (90/100.000 habitants) and the second cause of cancer related death in men. Standard treatment in this setting is androgen-deprivation therapy (TDA), which causes decrease in PSA levels and stabilization or regression of metastatic lesions. Responses in castration sensitive phase last in average 3 years, after which tumor is described to become independent from the androgenic stimuli, reaching a castration-resistance (mCRPC) state. At this point chemotherapy with docetaxel as well as second line treatments (abiraterone, enzalutamide, among others)have shown to improve survival in 4 months with mean survival from diagnosis of mCRPC of 24 months. Studies including CHAARTED and STAMPEDE have demonstrated that early treatment with docetaxel with ADT in patients with mCSPC prolongs overall survival, especially if high volume disease exists. This study describes the clinical characteristics, initial oncologic response and side effects profile of mCSPC treated with Docetaxel plus ADT. MATERIALS AND METHODS: Descriptive Retrospective study from May 2014 to July 2017. mCSPC patients with high volume disease (extra axial bone metastasis, visceral metastasis or Gleason 9-10) and ECOG 0-1 were included. Patients received ADT and 6 cycles of Docetaxel. Demographic, clinical and histopathological characteristicswere registered, together with PSA, radiologic data (RECIST V1.1) and toxicity (NCI CAE 4.0). RESULTS: 20 patients were included, median age 63 years (49-75 range). Median initial PSA 267,5 ng/ml (10,8-5550 range), and median follow up 6 months (3-20 range). Fourteen patients had Gleason > 8, 18presented bone metastasis and 9/14 viscerametastasis. Only 1 patient received previous local treatment. Median initialtime to initiation of Docetaxel post ADT was 3,1 (0-6,1) months.Sixteen patients completed docetaxel and 4 are still receiving treatment. There was no chemotherapy suspension due side effects. Most frequent side effects were diarrhea (8/20), neuropathy (5/20) and vomiting (2/20). Most were grade 1 and three patients presented grade 3 side effects (diarrhea, leukopenia and thrombocytopenia). No grade 4-5 side effects were reported.Ten patients reached PSA< 2 ng/m after 12 weeks of treatment, and 7 had biochemical relapse during follow up. One had complete radiologic response, 10 partial response, 7 remained stable and 2 showed progression of disease. CONCLUSION: The use of docetaxel in mCSPC isassociated to few side effects and none requiredsuspension of treatment. Treatment with Docetaxel exhibits promising results in terms of decrease in PSA, however longer follow up and greater number of patients are required to report benefits in overall survival.(AU)

INTRODUCTION: Between 5 and 10% of patients undergoing percutaneous nephrolithotomy (PCNL) develop postoperative sepsis 1, 2. Strategies to prevent infectious complications are based on information provided by preoperative midstream urine cultures (PMUC). The aim of this study is to evaluate the concordance of the microbiologic findings of PMUC, cultures of the renal stone (RSC) and urine obtained directly from the renal pelvis (RPUC) in patients undergoing PCNL. MATERIALS AND METHODS: This is a multicenter prospective study. The study included all patients who underwent PCNL from May 2013 to July 2015 in three academic hospitals. All patients underwent a PMUC. Samples for RPUC were obtained by renal puncture for PCNL. Stone fragments extracted during the procedure were sent for culture (RSC). Clinical variables, stone configuration, burden and microbiology reports of cultures were recorded. We analyzed concordance between cultures and association with infectious complications. RESULTS: One hundred and twenty-two patients underwent PCNL. Twenty-four percent had positive culture, 3.2% (4/122) PMUC, 14.7% (18/122) RPUC and 13.9% (17/122) RSC. Positive PMUC demonstrated multidrug-susceptible Escherichia coli and Staphylococcus aureus, while RPUC showed multidrug-resistant pathogens and/or fungus. Seven patients (5.7%) developed postoperative infectious complications prior to discharge. There was a weak correlation between PMUC and intraoperative urine cultures (RPUC and RSC). Concordance rate between RPUC and RSC was 83.3%. The most common isolated pathogens were multidrug-resistant bacteria or fungus. CONCLUSIONS: PMUC did not reflect the microbiological environment found in stones and urine directly obtained from the renal pelvis. Patients with postoperative infectious complications had negative PMUC with positive RPUC or RSC. RPUC and RSC can help guide prompt and appropriate antibiotic treatment for patients who develop postoperative infectious complications after PCNL.
