Systematic Review and Meta-analysis of Minimally Invasive Procedures for Surgical Inguinal Nodal Staging in Penile Carcinoma.

CONTEXT: There are several procedures for surgical nodal staging in clinically node-negative (cN0) penile carcinoma. OBJECTIVE: To evaluate the diagnostic accuracy, perioperative outcomes, and complications of minimally invasive surgical procedures for nodal staging in penile carcinoma. EVIDENCE ACQUISITION: A systematic review of the Medline, Embase, and Cochrane controlled trials databases and ClinicalTrials.gov was conducted. Published and ongoing studies reporting on the management of cN0 penile cancer were included without any design restriction. Outcomes included the false negative (FN) rate, the number of nodes removed, surgical time, and postoperative complications. EVIDENCE SYNTHESIS: Forty-one studies were eligible for inclusion. Four studies comparing robot-assisted (RA-VEIL) and video-endoscopic inguinal lymphadenectomy (VEIL) to open inguinal lymph node dissection (ILND) were suitable for meta-analysis. A descriptive synthesis was performed for single-arm studies on modified open ILND, dynamic sentinel node biopsy (DSNB) with and without preoperative inguinal ultrasound (US), and fine-needle aspiration cytology (FNAC). DSNB with US + FNAC had lower FN rates (3.5-22% vs 0-42.9%) and complication rates (Clavien Dindo grade I-II: 1.1-20% vs 2.9-11.9%; grade III-V: 0-6.8% vs 0-9.4%) in comparison to DSNB alone. Favourable results were observed for VEIL/RA-VEIL over open ILND in terms of major complications (2-10.6% vs 6.9-40.6%; odds ratio [OR] 0.18; p < 0.01). Overall, VEIL/RA-VEIL had lower wound-related complication rates (OR 0.14; p < 0.01), including wound infections (OR 0.229; p < 0.01) and skin necrosis (OR 0.16; p < 0.01). The incidence of lymphatic complications varied between 20.6% and 49%. CONCLUSIONS: Of all the surgical staging options, DSNB with inguinal US + FNAC had the lowest complication rates and high diagnostic accuracy, especially when performed in high-volume centres. If DSNB is not available, favourable results were also found for VEIL/RA-VEIL over open ILND. Lymphatic-related complications were comparable across open and video-endoscopic ILND. PATIENT SUMMARY: We reviewed studies on different surgical approaches for assessing lymph node involvement in cases with penile cancer. The results show that a technique called dynamic sentinel node biopsy with ultrasound guidance and fine-needle sampling has high diagnostic accuracy and low complication rates. For lymph node dissection in penile cancer cases, a minimally invasive approach may offer favourable postoperative outcomes.

European Association of Urology-American Society of Clinical Oncology Collaborative Guideline on Penile Cancer: 2023 Update.

CONTEXT: Penile cancer is a rare disease but has a significant impact on quality of life. Its incidence is increasing, so it is important to include new and relevant evidence in clinical practice guidelines. OBJECTIVE: To provide a collaborative guideline that offers worldwide physician and patient guidance for the management of penile cancer. EVIDENCE ACQUISITION: Comprehensive literature searches were performed for each section topic. In addition, three systematic reviews were conducted. Levels of evidence were assessed, and a strength rating for each recommendation was assigned according to the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) methodology. EVIDENCE SYNTHESIS: Penile cancer is a rare disease but its global incidence is increasing. Human papillomavirus (HPV) is the main risk factor for penile cancer and pathology should include an assessment of HPV status. The main aim of primary tumour treatment is complete tumour eradication, which has to be balanced against optimal organ preservation without compromising oncological control. Early detection and treatment of lymph node (LN) metastasis is the main determinant of survival. Surgical LN staging with sentinel node biopsy is recommended for patients with a high-risk (≥pT1b) tumour with cN0 status. While (inguinal) LN dissection remains the standard for node-positive disease, multimodal treatment is needed in patients with advanced disease. Owing to a lack of controlled trials and large series, the levels of evidence and grades of recommendation are low in comparison to those for more common diseases. CONCLUSIONS: This collaborative penile cancer guideline provides updated information on the diagnosis and treatment of penile cancer for use in clinical practice. Organ-preserving surgery should be offered for treatment of the primary tumour when feasible. Adequate and timely LN management remains a challenge, especially in advanced disease stages. Referral to centres of expertise is recommended. PATIENT SUMMARY: Penile cancer is a rare disease that significantly impacts quality of life. While the disease can be cured in most cases without lymph node involvement, management of advanced disease remains challenging. Many unmet needs and unanswered questions remain, underlining the importance of research collaborations and centralisation of penile cancer services.

The 2022 Updated European Association of Urology Guidelines on the Use of Adjuvant Immune Checkpoint Inhibitor Therapy for Renal Cell Carcinoma.

In KEYNOTE-564, adjuvant pembrolizumab, a PD-1 antibody, significantly improved disease-free survival (DFS) in localised clear-cell renal cell carcinoma (ccRCC) with a high risk of relapse. In 2021, the European Association of Urology RCC Guidelines Panel issued a weak recommendation for adjuvant pembrolizumab for high-risk ccRCC as defined by the trial until final overall survival data and results from other trials were available. Meanwhile, the primary DFS endpoints were not met for adjuvant atezolizumab (PD-L1 inhibitor; IMmotion010), adjuvant nivolumab plus ipilimumab (CheckMate 914), or perioperative nivolumab (PROSPER). Owing to heterogeneity, a meta-analysis is not recommended. Pembrolizumab remains the only immune checkpoint inhibitor currently recommended in this setting. Overall survival data are immature and biomarkers to predict outcome are lacking. Uncertainty exists and overtreatment is occurring. Treatment decisions should be made with caution and with the involvement of each patient. PATIENT SUMMARY: New results from three trials of immunotherapy after surgery for kidney cancer to reduce the risk of recurrence showed no improvement with these treatments. These results are in contrast to an earlier study that showed that the antibody pembrolizumab did extend the time before kidney cancer recurrence, even though it is not yet clear if overall survival is longer. Thus, we cautiously recommend pembrolizumab as additional treatment in high-risk kidney cancer after surgery, but patient preference should be carefully considered and the risk of overtreatment should be discussed.

European Association of Urology Guidelines Panel on Renal Cell Carcinoma Update on the New World Health Organization Classification of Kidney Tumours 2022: The Urologist's Point of View.

The fifth edition of the World Health Organization (WHO) classification of urogenital tumours published in 2022 will be implemented in the European Association of Urology guidelines on renal cell carcinoma for 2023. Here we provide an update summarising changes in the new WHO classification of renal tumours from a clinician perspective.

A Renewal of the TNM Staging System for Patients with Renal Cancer To Comply with Current Decision-making: Proposal from the European Association of Urology Guidelines Panel.

Over the past decade, only minor changes have been introduced in the TNM staging system for renal cancer. Conversely, many milestones and modifications in management of the disease have been achieved, especially for patients with locally advanced and metastatic cancers. The European Association of Urology guidelines panel proposes a new TNM classification scheme for staging of renal cell carcinoma to reflect these breakthrough clinical improvements.

Recurrence pattern in localized RCC: results from a European multicenter database (RECUR).

INTRODUCTION: The impact of open versus minimally invasive surgery on recurrence pattern in the management of localized renal cell carcinoma (RCC) remains uncertain. We thus aimed to determine the impact of surgical approach on survival and recurrence pattern. MATERIAL AND METHODS: This is a multi-institutional, matched cohort study on patients with pT1-3aN0M0 RCC from the RECUR database. After propensity score matching between open and minimally invasive surgery, disease-free (DFS) survival and risk of first recurrence according to recurrence site, namely local recurrence, abdominal/retroperitoneal, thoracic/mediastinal or uncommon site metastases were investigated with Cox regression analysis. Overall (OS) and Cancer Specific Survival (CSS) were also assessed. RESULTS: After matching, 1,019 patients who underwent open and 1,019 who underwent minimally invasive surgery were included (of which 70 robot-assisted). At 5.2 years of median follow-up, 130 patients in open and 125 in minimally invasive group experienced disease progression. A higher risk of local recurrence (HR 2.06; 95% CI 1.18-3.58, P-value = 0.01) and uncommon site metastases (HR 1.09; 95% CI 1.01-1.16; P-value = .04) was found for minimally invasive surgery relative to open surgery, while no difference was found in terms of DFS (HR 0.83; 95% CI 0.64-1.06; P-value = .14). No differences were found in terms of OS and CSS. Main limitation is the retrospective nature of the study. CONCLUSIONS: The risk for local recurrence and uncommon site metastases was higher for minimally invasive surgery compared to open surgery, although no differences were found for OS, CSS, and DFS.

European Association of Urology Guidelines on Renal Cell Carcinoma: The 2022 Update.

CONTEXT: The European Association of Urology (EAU) Renal Cell Carcinoma (RCC) Guideline Panel has prepared evidence-based guidelines and recommendations for the management of RCC. OBJECTIVE: To present a summary of the 2022 RCC guideline, which is based on a standardised methodology including systematic reviews (SRs) and provides transparent and reliable evidence for the management of RCC. EVIDENCE ACQUISITION: For the 2022 update, a new literature search was carried out with a cutoff date of May 28, 2021, covering the Medline, EMBASE, and Cochrane databases. The data search focused on randomised controlled trials (RCTs) and retrospective or controlled comparator-arm studies, SRs, and meta-analyses. Evidence synthesis was conducted using modified GRADE criteria as outlined for all the EAU guidelines. EVIDENCE SYNTHESIS: All chapters of the RCC guideline were updated on the basis of a structured literature assessment, and clinical practice recommendations were developed. The majority of the studies included were retrospective with matched or unmatched cohorts and were based on single- or multi-institution data or national registries. The exception was systemic treatment of metastatic RCC, for which there are several large RCTs, resulting in recommendations that are based on higher levels of evidence. CONCLUSIONS: The 2022 RCC guidelines have been updated by a multidisciplinary panel of experts using the highest methodological standards. These guidelines provide the most reliable contemporary evidence base for the management of RCC in 2022. PATIENT SUMMARY: The European Association of Urology panel for guidelines on kidney cancer has thoroughly evaluated the research data available to establish up-to-date international standards for the care of patients with kidney cancer.

Perioperative impact of body mass index on upper urinary tract and renal robot-assisted surgery: a single high-volume centre experience.

To assess the impact of body mass index (BMI) on peri-operative outcomes of kidney and upper tract robot-assisted surgery. Medical audit of patients who underwent robot-assisted kidney and upper tract cancer surgery at a single institution between 2017 and 2019, categorized on BMI into obese patients with a BMI ≥ 30 kg/m2 and a control group with BMI < 25 kg/m2. Patient and tumour characteristics, surgery time, intraoperative blood loss, intraoperative adverse events (AE) according to the European Association of Urology Intraoperative Adverse Incidents Classification (EAUiaiC), conversion- to-open/radical rate as well as 30-day postoperative AE according to Clavien-Dindo (CD) and length of inpatient stay were analyzed. 366 patients were identified, 141 with a BMI < 25 (normal-weight) and 225 BMI ≥ 30 (obesity). There were no significant differences between the groups in terms of age, gender, comorbidities, tumour size, TNM stage and type of surgery. Obese patients had a higher estimated blood loss (198.05 ml), surgery time (171.75 min), intraoperative AE (all grades) (14.67%, 95% CI (0.10-0.19) as well as adherent perinephric fat (APF) (14.22%, 95% CI (0.09-0.19)) in contrast to the control group (86.85 ml, 148.29 min, 7.04% and 2.12%, respectively). Hospital stay, major intraoperative AE (≥ 3) and major postoperative AE (CD > 2) distributed equally between groups. Robotic kidney and upper tract surgery in obese patients showed an increase in surgery time and blood loss potentially related to APF. However, obesity was not associated with conversion to open surgery or radical nephrectomy in nephron-sparing procedures, length of stay, major intraoperative AE or postoperative complications.

The role of morphometric and respiratory factors in predicting the severity and evolution of urinary symptoms in patients with obstructive sleep apnea syndrome.

OBJECTIVES: To assess the severity, evolution, and behaviour of several urinary symptoms in patients with obstructive sleep apnea syndrome (OSAS) before and after the treatment with continuous positive airway pressure (CPAP). METHODS: A prospective study was performed on patients with a recent diagnosis of sleep apnea confirmed by nocturnal sleep polygraphy and absence of medical urological past history. The symptom incidence was analysed seeking predictive factors for initial nocturia, nocturnal polyuria (NP), and unfavourable International Prostate Symptoms Score (IPSS) before and after a 1-year period of treatment using a CPAP device. Morphometric variables (body mass index, BMI; neck and abdominal diameter) and functional respiratory variables (FEV1, FVC, and FEV1/FVC) were analysed. A multivariate analysis was performed with a calculation of Pearson's correlation coefficient to establish a linear relation between the variables. RESULTS: A total of 43 patients completed the two-step study (IPSS and bladder diary before and after the CPAP treatment). IPSS decreased by 3.58 points. Nocturia decreased to once per night. Neck diameter, FEV1, and FEV1/FVC significantly predicted the initial severity of some lower urinary tract symptoms (LUTS), (p=0.015, p=0.029, p=0.008, respectively). Neck diameter, abdominal perimeter, and FEV1/FVC significantly predicted the LUTS evolution throughout the study (p=0.023, p=0.007, p=0.05, respectively). CONCLUSION: Some pre-treatment morphometry and spirometry parameters such as abdominal or neck diameter, FEV1, and FEV1/FVC were predictive of the severity and evolution of LUTS in patients with OSAS.

2021 Updated European Association of Urology Guidelines on the Use of Adjuvant Pembrolizumab for Renal Cell Carcinoma.

Adjuvant treatment of nonmetastatic high-risk renal cell carcinoma is an unmet medical need. In the past, several tyrosine kinase inhibitor trials have failed to demonstrate an improvement of disease-free survival (DFS) in this setting. Only one trial (S-TRAC) provided evidence for improved DFS with sunitinib but without an overall survival (OS) signal. Keynote-564 is the first trial of an immune checkpoint inhibitor that significantly improved DFS with adjuvant pembrolizumab, a programmed death receptor-1 antibody, in clear cell renal cell carcinoma with a high risk of relapse. The intention-to-treat population, which included a group of patients after metastasectomy and no evidence of disease (M1 NED), had a significant DFS benefit. The OS data are not mature as yet. The Renal Cell Carcinoma Guideline Panel issues a weak recommendation for the adjuvant use of pembrolizumab for high-risk clear cell renal carcinoma, as defined by the trial until final OS data are available. However, the trial reilluminates the discussion on when and in whom metastasectomy should be performed. Here, caution is necessary not to perform metastasectomy in patients with poor prognostic features and rapid progressive disease, which must be excluded by a confirmatory scan of disease status prior to planned metastasectomy. PATIENT SUMMARY: New data from the adjuvant immune checkpoint inhibitor trial with pembrolizumab (a programmed death receptor-1 antibody) for the treatment of high-risk clear cell renal cell carcinoma (ccRCC) after surgery showed that the drug prolonged the period of being cancer free significantly, although whether it prolonged survival remained uncertain. Consequently, pembrolizumab is cautiously recommended as additional (ie, adjuvant) treatment in high-risk ccRCC after kidney cancer surgery.

Impact of Body Mass Index on Survival of Metastatic Renal Cancer.

Obesity has been established as a risk factor for renal cell carcinoma (RCC). Recently, studies have described obesity as a probable protecting factor in the metastatic stage of RCC. In this study, we assessed the relationship between body mass index (BMI) and overall survival in patients under systemic therapy. The correlation between BMI and overall median survival was studied in 76 patients diagnosed with metastatic RCC under systemic therapy. The groups were divided into overweight and obesity (BMI > 25 kg/m2) and underweight or normal (BMI < 25 kg/m2). Statistical analysis was performed using the Cox regression model adjusted by gender. A total of 76 patients were studied: 16 women (21%) and 60 men (79%). The median BMI was 27.96 kg/m2; 24 patients (31.6%) had low BMI and 52 (68.4%) had high BMI. Median overall survival in the group with BMI > 25 kg/m2 was 17 months (95% confidence interval [CI]: 13-34 months), while in the group with BMI ≤ 25 kg/m2, it was 14 months (95% CI: 8-20 months). When adjusted by gender, the group with BMI > 25 kg/m2 presented a hazards ratio of 0.54 (95% CI: 0.30-0.96), P = 0.044 (Log Rank). A high BMI significantly acts as a protecting factor. We observed an increased overall survival of overweight and obese patients within the context of metastatic RCC under systemic treatment. These data confirm the findings published in other studies that suggest the role of lipid metabolism in this type of tumors.

[Gross hematuria and usefulness of urinary cytology: Experience at hematuria one stop clinic.] / Citología de orina por lavado y hematuria macroscópica monosintomática: experiencia sobre su utilidad en una consulta de alta resolución.

OBJECTIVE: To report the diagnostic accuracy and liability of the instrumentalized urine cytology in the preliminary study of monosyntomatic gross haematuria. METHODS: A retrospective, descriptive and analytic study of the patients that complained of macroscopic hematuria at the one-stop clinic between 2011 and 2018. The complementary tests requested were: kidney/bladder ultrasounds, urethrocystoscopy and urinary instrumentalized cytology. All the urine cytology samples were examined by the same pathologist. RESULTS: 1122 patients were reviewed with ultrasonography and cystoscopy. Bladder tumor was detected in 354 patients (31.5%) and other urological malignancies were found in 33 cases (2.9%). Urinary instrumentalized cytologies were collected in 804 patients (71.4%), being positive in 236 cases (29.4%). Sensitivity and specificity of urinary cytology for urothelial tumor detection were 55.1% and 85.7%, respectively. Cytology was positive in 181 patients (52.1%) with visible bladder tumors through cystoscopy, in 7 patients (0.87%) without visible bladder tumors. In 433 patients with ultrasonography and cystoscopy both negative, urine cytology was performed with a negative result (38.6%). CONCLUSION: The usefulness of instrumentalized urinary cytology to diagnose urothelial tumors is restricted in terms of monosymptomatic gross haematuria one stop clinic. It allows the diagnosis of a very limited number of cases tumors and leaves a significant number of them out. In case of gross hematuria and negative imaging, urine cytology can be requested as a differed complementary.

Should patients with low-risk renal cell carcinoma be followed differently after nephron-sparing surgery vs radical nephrectomy?

OBJECTIVE: To investigate whether pT1 renal cell carcinoma (RCC) should be followed differently after partial (PN) or radical nephrectomy (RN) based on a retrospective analysis of a multicentre database (RECUR). SUBJECTS: A retrospective study was conducted in 3380 patients treated for nonmetastatic RCC between January 2006 and December 2011 across 15 centres from 10 countries, as part of the RECUR database project. For patients with pT1 clear-cell RCC, patterns of recurrence were compared between RN and PN according to recurrence site. Univariate and multivariate models were used to evaluate the association between surgical approach and recurrence-free survival (RFS) and cancer-specific mortality (CSM). RESULTS: From the database 1995 patients were identified as low-risk patients (pT1, pN0, pNx), of whom 1055 (52.9%) underwent PN. On multivariate analysis, features associated with worse RFS included tumour size (hazard ratio [HR] 1.32, 95% confidence interval [CI] 1.14-1.39; P < 0.001), nuclear grade (HR 2.31, 95% CI 1.73-3.08; P < 0.001), tumour necrosis (HR 1.5, 95% CI 1.03-2.3; P = 0.037), vascular invasion (HR 2.4, 95% CI 1.3-4.4; P = 0.005) and positive surgical margins (HR 4.4, 95% CI 2.3-8.5; P < 0.001). Kaplan-Meier analysis of CSM revealed that the survival of patients with recurrence after PN was significantly better than those with recurrence after RN (P = 0.02). While the above-mentioned risk factors were associated with prognosis, type of surgery alone was not an independent prognostic variable for RFS nor CSM. Limitations include the retrospective nature of the study. CONCLUSION: Our results showed that follow-up protocols should not rely solely on stage and type of primary surgery. An optimized regimen should also include validated risk factors rather than type of surgery alone to select the best imaging method and to avoid unnecessary imaging. A follow-up of more than 3 years should be considered in patients with pT1 tumours after RN. A novel follow-up strategy is proposed.

The Impact of Histological Subtype on the Incidence, Timing, and Patterns of Recurrence in Patients with Renal Cell Carcinoma After Surgery-Results from RECUR Consortium.

BACKGROUND: Current follow-up strategies for patients with renal cell carcinoma (RCC) after curative surgery rely mainly on risk models and the treatment delivered, regardless of the histological subtype. OBJECTIVE: To determine the impact of RCC histological subtype on recurrence and to examine the incidence, pattern, and timing of recurrences to improve follow-up recommendations. DESIGN, SETTING, AND PARTICIPANTS: This study included consecutive patients treated surgically with curative intention (ie, radical and partial nephrectomy) for nonmetastatic RCC (cT1-4, M0) between January 2006 and December 2011 across 15 centres from 10 countries, as part of the euRopEan association of urology renal cell carcinoma guidelines panel Collaborative multicenter consortium for the studies of follow-Up and recurrence patterns in Radically treated renal cell carcinoma patients (RECUR) database project. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The impact of histological subtype (ie, clear cell RCC [ccRCC], papillary RCC [pRCC], and chromophobe RCC [chRCC]) on recurrence-free survival (RFS) was assessed via univariate and multivariate analyses, adjusting for potential interactions with important variables (stage, grade, risk score, etc.) Patterns of recurrence for all histological subtypes were compared according to recurrence site and risk criteria. RESULTS AND LIMITATIONS: Of the 3331 patients, 62.2% underwent radical nephrectomy and 37.8% partial nephrectomy. A total of 2565 patients (77.0%) had ccRCC, 535 (16.1%) had pRCC, and 231 (6.9%) had chRCC. The median postoperative follow-up period was 61.7 (interquartile range: 47-83) mo. Patients with ccRCC had significantly poorer 5-yr RFS than patients with pRCC and chRCC (78% vs 86% vs 91%, p = 0.001). The most common sites of recurrence for ccRCC were the lung and bone. Intermediate-/high-risk pRCC patients had an increased rate of lymphatic recurrence, both mediastinal and retroperitoneal, while recurrence in chRCC was rare (8.2%), associated with higher stage and positive margins, and predominantly in the liver and bone. Limitations include the retrospective nature of the study. CONCLUSIONS: The main histological subtypes of RCC exhibit a distinct pattern and dynamics of recurrence. Results suggest that intermediate- to high-risk pRCC may benefit from cross-sectional abdominal imaging every 6 mo until 2 yr after surgery, while routine imaging might be abandoned for chRCC except for abdominal computed tomography in patients with advanced tumour stage or positive margins. PATIENT SUMMARY: In this analysis of a large database from 15 countries around Europe, we found that the main histological subtypes of renal cell carcinoma have a distinct pattern and dynamics of recurrence. Patients should be followed differently according to subtype and risk score.

Updated European Association of Urology Guidelines on Renal Cell Carcinoma: Nivolumab plus Cabozantinib Joins Immune Checkpoint Inhibition Combination Therapies for Treatment-naïve Metastatic Clear-Cell Renal Cell Carcinoma.

Longer follow-up and new trial data from phase 3 randomised controlled trials investigating immune checkpoint blockade (PD-1 or its ligand PD-L1) in advanced clear-cell renal cell carcinoma (RCC) have recently become available. The CheckMate 9ER trial demonstrated an improved progression-free survival (PFS) and overall survival (OS) benefit for the combination of cabozantinib plus nivolumab. A Keynote-426 update demonstrated an ongoing OS benefit for pembrolizumab plus axitinib in the intention-to-treat population, with a PFS benefit seen across all International Metastatic Database Consortium (IMDC) subgroups, while an update of CheckMate 214 confirmed the long-term benefit of ipilimumab plus nivolumab in IMDC intermediate and poor risk patients. The RCC Guidelines Panel continues to recommend these tyrosine kinase inhibitors + immunotherapy (IO) combination across IMDC risk groups in advanced first-line RCC and dual immunotherapy of ipilimumab and nivolumab in IMDC intermediate and poor risk. PATIENT SUMMARY: New data from trials of immune checkpoint inhibitors for advanced kidney cancer confirm a survival benefit with the combination of cabozantinib plus nivolumab and pembrolizumab plus axitinib and ipilimumab plus nivolumab. These combination therapies are recommended as first-line treatment for advanced kidney cancer.

[Metastasis of breast carcinoma in the ureter. Presentation of a clinical case.] / Metástasis de carcinoma de mama en uréter. Presentación de un caso clínico.

OBJECTIVE: To assess the importance of long-term close follow-up in patients with breast carcinoma. MATERIALS AND METHODS: To present a case report. RESULTS: A case of a 55-year-old woman with history of lobular carcinoma of the breast is presented. She received neoadjuvant treatment, surgery and complementary chemotherapy and radiotherapy. In radiologic imaging studies, multiple bone metastases were diagnosed. The patient consulted for left lumbar pain. Radiologic studies revealed left hydronephrosis secondary to soft tissue lesion in pyeloureteral junction with renal functional impairment. A biopsyperformed using an endoscopic approach (ureteroscopy), diagnosed a metastasis of breast carcinoma in the ureter. CONCLUSION: Metastatic lesions in the ureter are extremely rare, even less frequent the ones with breast origin with around ten cases published worldwide. With the previous diagnosis of breast carcinoma, the probable ureteral compromise should be considered especially in patients with clinical and radiological symptoms of urinary tract obstruction. A well-timed and proper diagnosis may influence in prognosis and survival.

En biopsia realizada mediante abordaje endoscópico (ureteroscopia) se diagnosticó de metástasis de carcinoma de mama en uréter.CONCLUSIÓN: Las lesiones metastásicas en uréter son extremadamente infrecuentes siendo aún menos frecuentes las de origen mamario con alrededor de diez casos publicados mundialmente. Con el diagnóstico previo de carcinomade mama, el probable compromiso ureteral debe ser tomado en cuenta especialmente en pacientes con síntomas clínicos y radiológicos de obstrucción de la vía urinaria. Un diagnóstico oportuno es posible que influya en el pronóstico y supervivencia posterior.

Renal cell carcinoma and COVID-19 pandemia: Management strategies adapted to current practice. / Pandemia Covid-19 y cáncer renal: implicaciones y adaptación para un manejo óptimo de la enfermedad.

The COVID-19 pandemic caused by SARS-CoV-2 virus has caused an important health impact that has affected renal cell carcinoma management, among other urology areas. The high cancellation rate of surgeries, including those related to renal cancer, will cause an inevitable healthcare overload and probably a potential negative impact on its oncological outcomes, especially in locally advanced and metastatic renal cancer. Kidney cancer scenarios are quite different depending on their stage, distinguishing mainly between low priority of localized disease or high priority of locally advanced and metastatic under active treatment. The unknown pandemic duration and possibly fluctuating prevalence of the virus are likely to force an adaptation in the management of renal cell carcinoma among urology and oncology departments, ideally individualized ona case-by-case basis within multidisciplinary units. To this end, we present algorithms and tables regarding renal cell carcinoma management adapted to the COVID-19 period and stratified according to oncological stage, which might be useful for specialists dedicated to this uro-oncology area.

La pandemia COVID-19 causada por el virus SARS-CoV-2 ha provocado un importante impacto sanitario que ha afectado, entre otras áreas de la urología, al manejo del cáncer renal, tanto en su ámbito diagnóstico como de tratamiento. La elevada suspensión de intervenciones quirúrgicas, incluidas aquellas destinadas al tratamiento de esta patología, ocasionará una inevitable sobrecarga asistencial y quizá un potencial efecto deletéreo sobre sus resultados oncológicos, en especial en el cáncer renal localmente avanzado y en el metastásico. Los escenarios clínicos del carcinoma de células renales son bien distintos en función de su estadiaje, distinguiendo principalmente entre la baja prioridad de la enfermedad localizada o la alta prioridad del localmente avanzado y el metastásico en tratamiento activo. La duraciónin determinada y prevalencia posiblemente oscilante de la pandemia previsiblemente obligue a adaptar el manejo del cáncer renal en los servicios de urología y oncología, debiendo ser idealmente invidualizados según cada caso en el seno de unidades multidisciplinares. Para ello, se presentan algoritmos y tablas de manejo del cáncer renal adaptadas al periodo COVID-19 y estratificados según el estadio de la enfermedad, que puedan ser de utilidad para los especialistas dedicados a esta área de la uro-oncología.
