SGLT2 inhibition and three urological cancers: Up-to-date results.

OBJECTIVE: To identify the causal role of sodium-glucose cotransporter 2 (SGLT2) inhibition on three urological cancers. METHODS: Six single nucleotide polymorphisms associated with the expression level of SLC5A2, a proxy for SGLT2 inhibition, from a recent publication were extracted. Three common urological cancers, including bladder cancer, prostate cancer and kidney cancer, were analysed. The main cohort of bladder cancer was derived from UK Biobank (1279 cases and 372,016 controls). The prostate cancer cohort was from the Prostate Cancer Association Group to Investigate Cancer Associated Alterations in the Genome (PRACTICAL) consortium (79,148 cases and 61,106 controls). The kidney cancer phenotype was from the UK Biobank cohort of 463,010 individuals (1114 cases and 461,896 controls). Primary and sensitivity analysis were performed to validate the results. In vitro analysis was also incorporated to validate the Mendelian randomisation results. RESULTS: In primary analysis, SGLT2 inhibition was associated with reduced risk of bladder cancer (OR: 0.98, 95% CI: 0.97-0.99) per unit lowering of HbA1c level. A protective association was also observed for prostate cancer with odds ratio = 0.31 (95% CI = 0.21-0.47). However, we did not discover a causal relationship between SGLT2 inhibition and kidney cancer (OR: 1.00, 95% CI: 0.99-1.00). Sensitivity analysis and in vitro validation did not support the causal role of SGLT2 inhibition in increasing cancer risk. CONCLUSIONS: We did not find any evidence that SGLT2 inhibition could increase the risk of the three cancers. Even in some analysis, SGLT2 inhibition tended to show protective effects on the three urological cancers.

Urologic oncology considerations in transgender and gender diverse patients.

PURPOSE OF REVIEW: This review delves into the pressing issue of urologic oncology considerations within the transgender and gender-diverse (TGD) community. With estimates suggesting that TGD individuals constitute 0.3 to 0.5% of adults worldwide, and this number steadily rising, our review examines the barriers that impede the delivery of excellent quality care, particularly in the context of cancer diagnosis and treatment. RECENT FINDINGS: Recent findings highlight disparities in cancer screening, diagnosis, and treatment access for TGD individuals. These challenges are compounded by a dearth of research and the failure of healthcare systems to account for gender identity and its nuances in data collection. Main themes in the literature include the impact of gender-affirming hormone therapy and surgery on cancer risk, challenges in prostate cancer screening and management, and considerations pertinent to testicular and other urological cancers in TGD patients. SUMMARY: The implications for clinical practice and research are profound and emphasize the need for multidisciplinary approaches that cater to the unique healthcare needs of TGD individuals. This includes comprehensive strategies for inclusive and accurate data collection, alongside the development of evidence-based guidelines for cancer screening and management tailored specifically to this population.

De Novo Urological Malignancies After Renal Transplantation: An Asian 30-Year Experience.

BACKGROUND: As the incidence of urological malignancies after renal transplantation (RT) is observed to be greater than in the general population, a better understanding of them is important. We present our experience with urological tumors in RT recipients at our transplant center, and analyze their incidence, management and outcomes. MATERIALS AND METHODS: A retrospective analysis of 2177 RT recipients on follow-up at our center between 1990 and 2022 was conducted for de novo genitourinary malignancy. Patients diagnosed with malignancy before transplantation were excluded. Clinicopathological data at diagnosis and follow-up were collected and analyzed. Kaplan-Meier estimates were used to evaluate overall survival (OS) and cancer-specific survival (CSS). Statistical analysis was performed using IBM SPSS v.24 (IBM Corp., Armonk, NY, USA). RESULTS: The overall incidence of Urological malignancies was 3.9%, with 89 cancers diagnosed in 85 patients. Renal cell carcinoma was most common (n = 61, 68.5%), followed by prostate cancer (n = 10, 11.2%), urothelial carcinoma (n = 10, 11.2%), squamous cell carcinoma of the penis/scrotum (n = 7, 7.9%), and testicular cancer (n = 1, 1.1%). Mean duration between transplantation and diagnosis of malignancy was 9.9 (0.4-20.7) years. At a median follow-up of 4.6 (018.2) years, 27 deaths were seen; 7(25.9%) were due to urological malignancy. CSS rates were 86% and 78% at five and ten years, respectively, after diagnosis. CONCLUSION: We present one of the largest series of de novo urological malignancies observed over an extended 30-year follow-up of RT recipients, demonstrating an elevated risk in line with other studies. Regular surveillance for malignancies is advised, in order to ensure early diagnosis and management.

Urological cancer statistics on incidence from 1975 to 2019 and mortality from 1958 to 2022 in Japan.

BACKGROUND: In Japan, comprehensive cancer statistics are collected through cancer registries. However, data on urological cancers are rarely summarized or published in research papers. METHODS: This retrospective study was performed using publicly available statistical data on urological cancers (prostate cancer [PCa], bladder cancer [BCa], and cancers of kidney and urinary tract [except urinary bladder]) in Japan, including a summary of the Ministry's mortality statistics, cancer incidence statistics from the Regional Cancer Registries through 2015, and the National Cancer Registry statistics from 2016. We examined the incidence and mortality rates of urological cancers stratified by age groups. RESULTS: The number of new cases of PCa, BCa, and cancers of kidney and urinary tract (except urinary bladder) in 2019 was 94,748, 23,383, and 30,458, respectively, and the number of deaths in 2022 was 13,439, 9,598, and 9,795, respectively. The incidence and mortality rates of urological cancers have consistently increased. Since 2000, there has been a noteworthy increase in the mortality rate of urological cancers among individuals aged > 85 years. The incidence and mortality rates of BCa and cancers of kidney and urinary tract (except urinary bladder) were significantly higher in males than in females. CONCLUSIONS: Urological cancers in very elderly patients (> 85 years) will become increasingly important in the future.

Real-world epidemiology and treatment patterns of patients with locally advanced or metastatic urothelial carcinoma: Retrospective analysis of Diagnosis Procedure Combination claims data in Japan.

OBJECTIVES: Evaluate real-world epidemiologic trends and treatment patterns in newly diagnosed patients with locally advanced or metastatic urothelial carcinoma (la/mUC) in Japan. METHODS: This retrospective analysis included adults with newly diagnosed la/mUC in Japan (January 2015-December 2019) from a nationwide-linked electronic medical record Diagnostic Procedure Combination claims dataset. Outcomes included epidemiologic trends (incidence and prevalence), baseline demographics, clinical characteristics, and treatment patterns in newly diagnosed patients with la/mUC before (2015-2017) and after (2018-2019) approval of pembrolizumab in Japan. RESULTS: Of 975 patients included, 76.4% were men; 71.6% were aged 70 years or older. Most cases (70.5%) were of the bladder. Between 2015 and 2019, the annual age-adjusted incidence increased from 6.8 to 12.4 per 100 000; the annual age-adjusted period prevalence increased from 13.0 to 25.2 per 100 000; and 307 (31.5%) and 668 (68.5%) patients were diagnosed from 2015 to 2017 and 2018 to 2019, respectively. Overall, 731 (75%) patients received systemic anticancer therapy; all received 1 line and 50.2% received 2 lines of therapy; 78.3% of patients received gemcitabine plus platinum-based therapy and 2.2% received pembrolizumab as first-line treatment. First-line treatment rates increased from 69.4% to 77.5% after pembrolizumab approval. Of 367 patients who received second-line treatment, 22.3% received gemcitabine plus platinum-based therapy; 14.7% received pembrolizumab. CONCLUSIONS: In the Japanese regions considered, incidence and prevalence of newly diagnosed la/mUC increased over time and first-line treatment with pembrolizumab increased after approval.

Urinary albumin excretion and cancer risk: the PREVEND cohort study.

BACKGROUND: Chronic kidney disease (CKD) is believed to be associated with an increased risk for cancer, especially urinary tract cancer. However, previous studies predominantly focused on the association of decreased estimated glomerular filtration rate (eGFR) with cancer. In this study, we investigated the association of albuminuria with cancer incidence, adjusted for eGFR. METHODS: We included 8490 subjects in the Prevention of Renal and Vascular End-stage Disease (PREVEND) observational study. Urinary albumin excretion (UAE) was measured in two 24-hour urine specimens at baseline. Primary outcomes were the incidence of overall and urinary tract cancer. Secondary outcomes were the incidence of other site-specific cancers, and mortality due to overall, urinary tract, and other site-specific cancers. RESULTS: Median baseline UAE was 9.4 (IQR, 6.3-17.8) mg/24 h. During a median follow-up of 17.7 years, 1341 subjects developed cancer (of which 177 were urinary tract cancers). After multivariable adjustment including eGFR, every doubling of UAE was associated with a 6% (hazard ratios (HR), 1.06, 95% confidence intervals (CI), 1.02-1.10), and 14% (HR, 1.14, 95% CI, 1.04-1.24) higher risk of overall and urinary tract cancer incidence, respectively. Except for lung and hematological cancer, no associations were found between UAE and the incidence of other site-specific cancer. Doubling of UAE was also associated with a higher risk of mortality due to overall and lung cancer. CONCLUSIONS: Higher albuminuria is associated with a higher incidence of overall, urinary tract, lung, and hematological cancer, and with a higher risk of mortality due to overall and lung cancers, independent of baseline eGFR.

Impact of smoking on urologic cancers: a snapshot of current evidence.

PURPOSE: The purpose of this paper is to present evidence regarding the associations between smoking and the following urologic cancers: prostate, bladder, renal, and upper tract urothelial cancer (UTUC). METHODS: This is a narrative review. PubMed was queried for evidence-based analyses and trials regarding the associations between smoking and prostate, bladder, renal, and UTUC tumors from inception to September 1, 2022. Emphasis was placed on articles referenced in national guidelines and protocols. RESULTS: Prostate-multiple studies associate smoking with higher Gleason score, higher tumor stage, and extracapsular invasion. Though smoking has not yet been linked to tumorigenesis, there is evidence that it plays a role in biochemical recurrence and cancer-specific mortality. Bladder-smoking is strongly associated with bladder cancer, likely due to DNA damage from the release of carcinogenic compounds. Additionally, smoking has been linked to increased cancer-specific mortality and higher risk of tumor recurrence. Renal-smoking tobacco has been associated with tumorigenesis, higher tumor grade and stage, poorer mortality rates, and a greater risk of tumor recurrence. UTUC-tumorigenesis has been associated with smoking tobacco. Additionally, more advanced disease, higher stage, lymph node metastases, poorer survival outcomes, and tumor recurrence have been linked to smoking. CONCLUSION: Smoking has been shown to significantly affect most urologic cancers and has been associated with more aggressive disease, poorer outcomes, and tumor recurrence. The role of smoking cessation is still unclear, but appears to provide some protective effect. Urologists have an opportunity to engage in primary prevention by encouraging cessation practices.

Use of genomic markers to improve epidemiologic and clinical research in urology.

PURPOSE OF REVIEW: Urologic cancers result from the appearance of genomic alterations in the target organ due to the combination of genetic and environmental factors. Knowledge of the genomic markers involved in their etiology and mechanisms for their development continue to progress. This reviewed provides an update on recent genomic studies that have informed epidemiologic and clinical research in urology. RECENT FINDINGS: Inherited variations are an established risk factor for urologic cancers with significant estimates of heritability for prostate, kidney, and bladder cancer. The roles of both rare germline variants, identified from family-based studies, and common variants, identified from genome-wide association studies, have provided important information about the genetic architecture for urologic cancers. Large-scale analyses of tumors have generated genomic, epigenomic, transcriptomic, and proteomic data that have also provided novel insights into etiology and mechanisms. These tumors characteristics, along with the associated tumor microenvironment, have attempted to provide more accurate risk stratification, prognosis of disease and therapeutic management. SUMMARY: Genomic studies of inherited and acquired variation are changing the landscape of our understanding of the causes of urologic cancers and providing important translational insights for their management. Their use in epidemiologic and clinical studies is thus essential.

Temporal trends of de novo urological malignancy in renal transplant recipients without a cancer history: A longitudinal cohort study.

BACKGROUND: The incidence of malignancies after successful kidney transplantation has historically been higher than in the general population, with adverse impact on clinical outcomes. However, uncertainty remains as to which cancers occur at what time points after kidney transplantation. METHODS: We conducted a longitudinal cohort study to investigate the temporal trends and topographic patterns of de novo malignancies to optimize surveillance protocols and improve transplant outcome in renal transplant recipients. Measurement of death and cancer events was performed to calculate the cumulative risk of events of interest. RESULTS: Between 2000 and 2013, 3169 renal transplant recipients were retrospectively screened; 3035 (96%) of them met eligibility criteria and were evaluated with a follow-up of 27612 person-years. There was suboptimal overall survival and malignancy-free survival in renal transplant recipients compared to reference groups (HR: 1.65; 95% CI: 1.50-1.82; p < .001; HR: 2.33; 95% CI: 2.04-2.66; p < .001, respectively). Among renal transplant recipients, urological malignancies were predominant (57.5%), followed by digestive tract malignancies (21.4%). The cancer risks of the urinary bladder and upper urinary tract were lower in male subjects (HR: .48; 95% CI: .33-.72; p < .001; HR: .34; 95% CI: .20-.59; p < .001, respectively). The temporal trends of urological malignancies among renal transplant recipients were expressed in a bimodal pattern, with M-shaped peaks at 3 and 9 years, with gender disparity. CONCLUSIONS: In renal transplant recipients, cancer occurrences are shown as M-shaped twin peaks. Our study highlights that specific customized 'targeted' strategies for cancer surveillance programs are required to optimize posttransplant care.

Association of metabolic syndrome and its components with the risk of urologic cancers: a prospective cohort study.

OBJECTIVE: To investigate the association between metabolic syndrome (MetS) and its components and the risk of developing urologic cancers. METHODS: This study included 101,510 observation subjects from May 2006 to December 2007. The subjects received questionnaires and were subjected to clinical and laboratory examinations to collect data on baseline population characteristics, waist circumference (WC), blood pressure (BP), blood glucose, blood lipids, lifestyle, and past disease history. Finally, follow-up was conducted from the date of recruitment to December 31, 2019. Cox proportional hazards modelling was applied to analyze the association between MetS and its components and the risk of developing urologic cancers. RESULTS: A total of 97,975 observation subjects met the inclusion criteria. The cumulative follow-up period included 1,209,178.65 person-years, and the median follow-up time was 13.03 years. During the follow-up period, 485 cases of urologic cancers (165 cases of kidney cancer, 134 cases of prostate cancer, 158 cases of bladder cancer, and 28 cases of other urologic cancers) were diagnosed. The log-rank test results for the cumulative incidences of urologic cancer, kidney cancer, and prostate cancer indicated significant (P < 0.01) differences between the MetS and non-MetS groups (0.70% vs. 0.48%, 0.27% vs. 0.15%, and 0.22% vs. 0.13%, respectively). Compared to the non-MetS group, the risk of developing urologic [HR (95% CI) = 1.29 (1.08-1.55)], kidney [HR (95% CI) = 1.74 (1.28-2.37)], and prostate [HR (95% CI) = 1.47 (1.04-2.07)] cancers was significantly higher in the MetS group. In the MetS group, elevated BP increased the risk of developing of urologic cancer [HRs (95% CI) = 1.35 (1.10-1.66)] and kidney cancer [HR (95% CI) = 1.74 (1.21-2.51)], while central obesity increased the risk of developing prostate cancer [HR (95% CI) = 1.68 (1.18-2.40)]. CONCLUSIONS: MetS increased the risk of developing urologic, kidney, and prostate cancers but had no association with the development of bladder cancer.

Trends in the age of hospitalized patients with urological cancers: A 17-year experience.

OBJECTIVES: To investigate the impact of global aging on the trends in the age of hospitalized patients with a urological cancer diagnosis. METHODS: We retrospectively evaluated a cumulative total of 10 652 cases of referred patients (n = 6637) with a urological disease who were hospitalized in our institution between January 2005 and December 2021. We compared age and the proportion of patients aged ≥80 years among patients who were hospitalized in the urological ward between the period of 2005-2013 and that of 2014-2021. RESULTS: We identified 8168 hospitalized patients with urological cancer. The median age was significantly increased in patients with urological cancer between the periods of 2005-2013 and 2014-2021. The proportion of hospitalized patients with urological cancer aged ≥80 years was significantly increased between the periods of 2005-2013 (9.3%) and 2014-2021 (13.8%). The median ages of the patients with urothelial cancer (UC) and renal cell carcinoma (RCC), but not the median age of those with prostate cancer (PC), were significantly increased between the study periods. The proportion of hospitalized patients with UC, but not the proportions of those with PC and RCC, aged ≥80 years was significantly increased between the study periods. CONCLUSIONS: The age of patients with urological cancer who were hospitalized in the urological ward and the proportion of patients with UC aged ≥80 years significantly increased over the entire study period.

Risk of genitourinary malignancy in patients that receive anticoagulant or antiplatelet therapy.

OBJECTIVES: Haematuria is a common indication for a urology evaluation. In many cases, its cause is not determined unequivocally, but it does not pose any threat to the patient. However, it can represent the first symptom of urinary tract cancer. BACKGROUND: The present study aimed to compare the risk of urological malignancies in patients with haematuria who received antiplatelet or anticoagulant therapy versus those who did not. METHODS: This prospective study included 562 patients with haematuria during the period of 2018‒2021. Among these, 129 patients had macroscopic haematuria. All patients underwent a urinary tract ultrasound, CT with urography, and cystoscopy. Patients with suspected malignancy underwent an appropriate surgical procedure with a pathology examination. Data were analysed with univariate and multiple logistic regression. RESULTS: The incidence rates of malignancies were 21.5 % overall, and 44.2 % and 14.8 % among patients with macroscopic and microscopic haematuria, respectively. Univariate regression showed that the odds of malignancy was significantly higher among patients with antiplatelet therapy compared to patients without antiplatelet therapy (OR: 1.88, 95% CI: 1.14‒3.05). In contrast, anticoagulation therapy did not significantly increase the odds of malignancy compared to no anticoagulation therapy (OR: 1.45, 95% CI: 0.74‒2.69). However, a multiple logistic regression model that included other known risk factors (e.g., sex or age) showed similar odds of malignancy among these patient groups. CONCLUSIONS: Malignancy risk for patients who received anticoagulant or antiplatelet therapy was similar to the risk observed in the general population. Antiplatelet and anticoagulant therapy were not significant risk factors of urological malignancy in patients with haematuria. The results from the present study will be used in a power analysis for an upcoming multicentre study (Tab. 4, Ref. 17).

UROTHELIAL CARCINOMA BEFORE AND DURING THE COVID-19 PANDEMIC IN CROATIA - A SINGLE-CENTER STUDY.

The aim of this study was to compare the number of newly diagnosed, histopathologically confirmed cases of urothelial carcinoma before and during the COVID-19 pandemic at the Zagreb University Hospital Center. We retroactively collected and analyzed 300 histopathologically confirmed urothelial carcinoma between January 1, 2019, and December 31, 2020, at the Department of Pathology and Cytology, Zagreb University Hospital Center. Our results showed that during the COVID-19 pandemic, there was a statistically significant decrease (p=0.001; χ2-test) in the number of newly diagnosed, histopathologically confirmed cases of urothelial carcinoma at the Zagreb University Hospital Center. There was a decrease in the absolute number of newly diagnosed urothelial carcinoma by 25.8% in the observed time of the pandemic (March 19, 2020 to December 31, 2020) as compared to the same period of the previous year (March 19, 2019 to December 31, 2019). Our study is the first study of this type based on the number of newly diagnosed urothelial carcinoma in Croatia. Observing the early period of the pandemic, our results provide important foundation for future monitoring and long-term consequences of the pandemic on the morbidity and mortality of urothelial carcinoma.

COVID-19 pandemic impact on uro-oncological disease outcomes at an Italian tertiary referral center.

PURPOSE: To assess differences in referral and pathologic outcomes for uro-oncology cases prior to and during the COVID pandemic, comparing clinical and pathological data of cancer surgeries performed at an academic referral center between 2019 and 2020. METHODS: We collected data of 880 prostate biopsies, 393 robot-assisted radical prostatectomies (RARP) for prostate cancer (PCa), 767 trans-urethral resections of bladder tumor (TURB) and 134 radical cystectomies (RC) for bladder cancer (BCa), 29 radical nephro-ureterectomies (RNU) for upper tract urothelial carcinoma, 130 partial nephrectomies (PN) and 12 radical nephrectomies (RN) for renal cancer, and 41 orchifunicolectomies for testicular cancer. Data of patients treated in 2019 (before COVID-19 pandemic) were compared to patients treated in 2020 (during pandemic). RESULTS: No significant decline in uro-oncological surgical activity was seen between 2019 and 2020. No significant increase in time between diagnosis and surgery was observed for all considered cancers. No differences in terms of main pathologic features were observed in patients undergoing RARP, TURB, RNU, RN/PN, or orchifunicolectomy. A higher proportion of ISUP grade 3 and 4 PCa were diagnosed in 2020 at biopsy (p = 0.001), but this did not translate into worse pathological grade/stage at RARP. In 2020, more advanced disease features were seen after RC, including lymph node involvement (p = 0.01) and non-organ confined disease (p = 0.02). CONCLUSION: Neither decline in uro-oncologic activity nor delay between diagnosis and treatment was observed at our institution during the first year of COVID-19 pandemic. No significant worsening of cancer disease features was found in 2020 except for muscle-invasive BCa.

The relationship between urologic cancer outcomes and national Human Development Index: trend in recent years.

OBJECTIVES: To describe the influence of the socioeconomic development on worldwide age-standardized incidence and mortality rates, as well as mortality-to-incidence ratio (MIR) and 5-year net survival of urologic cancer patients in recent years. METHODS: The Human Development Index (HDI) values were obtained from the United Nations Development Programme, data on age-standardized incidence/mortality rates of prostate, bladder and kidney cancer were retrieved from the GLOBOCAN database, 5-year net survival was provided by the CONCORD-3 program. We then evaluated the association between incidence/MIR/survival and HDI, with a focus on geographic variability as well as temporal patterns during the last 6 years. RESULTS: Urologic cancer incidence rates were positively correlated with HDIs, and MIRs were negatively correlated with HDIs. Prostate cancer survival also correlated positively with HDIs, solidly confirming the interrelation among cancer indicators and socioeconomic factors. Most countries experienced incidence decline over the most recent 6 years, and a substantial reduction in MIR was observed. Survival rates of prostate cancer have simultaneously improved. CONCLUSION: Development has a prominent influence on urologic cancer outcomes. HDI values are significantly correlated with cancer incidence, MIR and survival rates. HDI values have risen along with increased incidence and improved outcomes of urologic caner in recent years.

Renal outcomes in adult patients with horseshoe kidney.

BACKGROUND: Horseshoe kidney (HSK) is a congenital disorder that is usually asymptomatic, but that increases the risks of kidney stones and infectious disease. However, renal outcomes such as end-stage renal disease (ESRD) in patients with HSK remain unclear. METHODS: In total, 146 patients with HSK (age of ≥20 years) from two tertiary hospitals were included in this study. Control individuals who underwent medical check-ups were selected by matching for age, sex, serum creatinine level, hypertension and diabetes. The hazard ratios (HRs) for the risks of ESRD and all-cause mortality were calculated after adjustment for multiple variables. RESULTS: The proportions of HSK-related complications for obstruction, kidney stones, urinary tract infection and urogenital cancer were 26, 25, 19 and 4%, respectively. During the median follow-up period of 9 years (maximum 32 years), the incidence of ESRD was 2.6/10 000 person-years. The risk of ESRD in patients with HSK was higher than in control individuals [adjusted HR = 7.6; 95% confidence interval (CI) 1.14-50.47]. All-cause mortality did not differ between the two groups (adjusted HR = 0.6; 95% CI 0.08-4.29). CONCLUSIONS: Patients with HSK are at risk of ESRD, which may be attributable to the high prevalence of complications. Accordingly, these patients should be regarded as having chronic kidney disease and require regular monitoring of both kidney function and potential complications.

Global change of surgical and oncological clinical practice in urology during early COVID-19 pandemic.

OBJECTIVES: While the coronavirus disease 2019 (COVID-19) pandemic captures healthcare resources worldwide, data on the impact of prioritization strategies in urology during pandemic are absent. We aimed to quantitatively assess the global change in surgical and oncological clinical practice in the early COVID-19 pandemic. METHODS: In this cross-sectional observational study, we designed a 12-item online survey on the global effects of the COVID-19 pandemic on clinical practice in urology. Demographic survey data, change of clinical practice, current performance of procedures, and current commencement of treatment for 5 conditions in medical urological oncology were evaluated. RESULTS: 235 urologists from 44 countries responded. Out of them, 93% indicated a change of clinical practice due to COVID-19. In a 4-tiered surgery down-escalation scheme, 44% reported to make first cancellations, 23% secondary cancellations, 20% last cancellations and 13% emergency cases only. Oncological surgeries had low cancellation rates (%): transurethral resection of bladder tumor (27%), radical cystectomy (21-24%), nephroureterectomy (21%), radical nephrectomy (18%), and radical orchiectomy (8%). (Neo)adjuvant/palliative treatment is currently not started by more than half of the urologists. COVID-19 high-risk-countries had higher total cancellation rates for non-oncological procedures (78% vs. 68%, p = 0.01) and were performing oncological treatment for metastatic diseases at a lower rate (35% vs. 48%, p = 0.02). CONCLUSION: The COVID-19 pandemic has affected clinical practice of 93% of urologists worldwide. The impact of implementing surgical prioritization protocols with moderate cancellation rates for oncological surgeries and delay or reduction in (neo)adjuvant/palliative treatment will have to be evaluated after the pandemic.

The incidence and prevalence of upper tract urothelial carcinoma: a systematic review.

BACKGROUND: Upper tract urothelial carcinoma (UTUC) is a rare urological cancer that is still an important public health concern in many areas around the world. Although UTUC has been linked to a number of risk factors, to our knowledge no systematic review has been published on the overall incidence and prevalence of de-novo UTUC. This review aimed to examine the global epidemiology of UTUC to provide clinicians and public health specialists a better understanding of UTUC. METHODS: A systematic search was conducted on MEDLINE, Embase, and the Web of Science using a detailed search strategy. Observational epidemiological studies describing the incidence and prevalence of de-novo UTUC in adults were included, and the Joanna Briggs Institute checklist was used for critical appraisal and data extraction of the studies selected. RESULTS: The systematic search identified 3506 papers, of which 59 papers were included for qualitative synthesis. The studies selected included data ranging from the years 1943 to 2018. A comprehensive qualitative synthesis of the data was performed. UTUC incidence generally varied according to age (higher with increasing age), sex (unclear), race (unclear), calendar time (increased, stable, or decreased according to region), geographical region (higher in Asian countries), occupation (higher in seamen and printers), and other population characteristics. Prevalence was only reported by one study, which showed UTUC to have the highest incidence of the rare urogenital cancers in Europe. CONCLUSION: This systematic review highlights an increased incidence of UTUC in certain groups, including increasing age and certain occupations such as seamen. The incidence of UTUC also varies between certain geographical regions. The trend of UTUC incidence for sex, race, and calendar time is less clear due to a wide variety of metrics used by the studies identified. More studies are also required on the prevalence of UTUC to understand its disease burden. Trial registration This review was registered on PROSPERO (registration number CRD42019134255).

Urological Cancers and Kidney Transplantation: a Literature Review.

PURPOSE OF REVIEW: The aim of this review is to provide an overview of epidemiology, risk factors, and treatment of urological malignancies in renal transplant recipients (RTR). RECENT FINDINGS: Although optimal immunosuppressive therapy and cancer management in these patients remain controversial, adherence to general guidelines is recommended. Kidney transplantation is recognized as the standard of care for the treatment of end-stage renal disease (ESRD) as it offers prolonged survival and better quality of life. In the last decades, survival of RTRs has increased as a result of improved immunosuppressive therapy; nonetheless, the risk of developing cancer is higher among RTRs compared to the general population. Urological malignancies are the second most common after hematological cancer and often have more aggressive behavior and poor prognosis.

Individual-risk-score for urinary tract malignancy in patients with microscopic hematuria.

AIM: To determine the patients who can be safely exempted from undergoing unnecessary diagnostic procedures for microscopic hematuria (MH) evaluation by using the developed individual-risk-scoring system. MATERIALS AND METHODS: The patients who underwent a complete urological evaluation for MH were identified retrospectively. The risk factors for urinary malignancy which defined in the 2020 American Urological Association/Society of Urodynamics, Female Pelvic Medicine & Urogenital Reconstruction guidelines were recorded for each patient. Multivariable logistic regression was performed to establish a predictive risk-scoring system. The odds ratios obtained as a result of the logistic regression analysis were scored. RESULTS: A total of 1461 patients who had undergone a complete urological evaluation for MH were identified. The urinary malignancy rate was 3.4% (50 of the 1461 patients). According to the odds ratios, age >40 was calculated as 1 point; male gender, 2 points; smoking history, 4 points; presence of occupational risk factor, 1 point; and presence of macroscopic hematuria, 2 points. For the cut-off risk score, 5 points was found to be the most appropriate score according to the sensitivity and specificity levels. The patients with risk scores of 5 points or lower were considered to be in the low-risk group for urinary tract malignancy. CONCLUSION: The patients with a risk score of 5 points or above require complete urological evaluation. The results of the present study may reduce the number of patients undergoing unnecessary urological evaluation.
