Previous studies have reported significant variation in prostate cancer rates and trends mainly due to differences in detection practices, availability of treatment, and underlying genetic ...susceptibility.
To assess recent worldwide prostate cancer incidence, mortality rates, and trends using up-to-date incidence and mortality data.
We present estimated age-standardized prostate cancer incidence and mortality rates by country and world regions for 2018 based on the GLOBOCAN database. We also examined rates and temporal trends for incidence (44 countries) and mortality (76 countries) based on data series from population-based registries.
The highest estimated incidence rates were found in Australia/New Zealand, Northern America, Western and Northern Europe, and the Caribbean, and the lowest rates were found in South-Central Asia, Northern Africa, and South-Eastern and Eastern Asia. The highest estimated mortality rates were found in the Caribbean (Barbados, Trinidad and Tobago, and Cuba), sub-Saharan Africa (South Africa), parts of former Soviet Union (Lithuania, Estonia, and Latvia), whereas the lowest rates were found in Asia (Thailand and Turkmenistan). Prostate cancer incidence rates during the most recent 5 yr declined (five countries) or stabilized (35 countries), after increasing for many years; in contrast, rates continued to increase for four countries in Eastern Europe and Asia. During the most recent 5 data years, mortality rates among the 76 countries examined increased (three countries), remained stable (59 countries), or decreased (14 countries).
As evident from available data, prostate cancer incidence and mortality rates have been on the decline or have stabilized recently in many countries, with decreases more pronounced in high-income countries. These trends may reflect a decline in prostate-specific antigen testing (incidence) and improvements in treatment (mortality).
We examined recent trends in prostate cancer incidence and mortality rates in 44 and 76 countries, respectively, and found that rates in most countries stabilized or decreased.

Patients with treatment-naïve metastatic urothelial carcinoma are grouped according to platinum eligibility based on clear definitions. In general, first-line treatment consists of platinum-based ...chemotherapy in which cisplatin is to be preferred to carboplatin. Patients who are cisplatin ineligible but carboplatin eligible should receive carboplatin-gemcitabine combination chemotherapy. In case of positive programmed death ligand 1 (PD-L1) status, treatment with checkpoint inhibitors (atezolizumab or pembrolizumab) could be an alternative option.
Patients unfit for both cisplatin and carboplatin (platinum unfit) can be considered for immunotherapy (U.S. Food and Drug Administration approved irrespective of PD-L1 status and European Medicines Agency approved only for PD-L1 positive) or can receive best supportive care.
Treatment of metastatic urothelial carcinoma is currently undergoing a rapid evolution.
This overview presents the updated European Association of Urology (EAU) guidelines for metastatic urothelial carcinoma.
A comprehensive scoping exercise covering the topic of metastatic urothelial carcinoma is performed annually by the Guidelines Panel. Databases covered by the search included Medline, EMBASE, and the Cochrane Libraries, resulting in yearly guideline updates.
Platinum-based chemotherapy is the recommended first-line standard therapy for all patients fit to receive either cisplatin or carboplatin. Patients positive for programmed death ligand 1 (PD-L1) and ineligible for cisplatin may receive immunotherapy (atezolizumab or pembrolizumab). In case of nonprogressive disease on platinum-based chemotherapy, subsequent maintenance immunotherapy (avelumab) is recommended. For patients without maintenance therapy, the recommended second-line regimen is immunotherapy (pembrolizumab). Later-line treatment has undergone recent advances: the antibody-drug conjugate enfortumab vedotin demonstrated improved overall survival and the fibroblast growth factor receptor (FGFR) inhibitor erdafitinib appears active in case of FGFR3 alterations.
This 2021 update of the EAU guideline provides detailed and contemporary information on the treatment of metastatic urothelial carcinoma for incorporation into clinical practice.
In recent years, several new treatment options have been introduced for patients with metastatic urothelial cancer (including bladder cancer and cancer of the upper urinary tract and urethra). These include immunotherapy and targeted treatments. This updated guideline informs clinicians and patients about optimal tailoring of treatment of affected patients.

Summary Bladder cancer is a complex disease associated with high morbidity and mortality rates if not treated optimally. Awareness of haematuria as the major presenting symptom is paramount, and ...early diagnosis with individualised treatment and follow-up is the key to a successful outcome. For non-muscle-invasive bladder cancer, the mainstay of treatment is complete resection of the tumour followed by induction and maintenance immunotherapy with intravesical BCG vaccine or intravesical chemotherapy. For muscle-invasive bladder cancer, multimodal treatment involving radical cystectomy with neoadjuvant chemotherapy offers the best chance for cure. Selected patients with muscle-invasive tumours can be offered bladder-sparing trimodality treatment consisting of transurethral resection with chemoradiation. Advanced disease is best treated with systemic cisplatin-based chemotherapy; immunotherapy is emerging as a viable salvage treatment for patients in whom first-line chemotherapy cannot control the disease. Developments in the past 2 years have shed light on genetic subtypes of bladder cancer that might differ from one another in response to various treatments.
Management of bladder cancer (BC) is primarily driven by stage, grade, and biological potential. Knowledge of each is derived using clinical, histopathological, and radiological investigations. This ...multimodal approach reduces the risk of error from one particular test, but may present a staging dilemma when results conflict. Multiparametric magnetic resonance imaging (mpMRI) may improve patient care through imaging of the bladder with better resolution of the tissue planes than computed tomography and without radiation exposure.
To define a standardized approach to imaging and reporting mpMRI for BC, by developing a VI-RADS score.
We created VI-RADS (Vesical Imaging-Reporting And Data System) through consensus using existing literature.
We describe standard imaging protocols and reporting criteria (including size, location, multiplicity, and morphology) for bladder mpMRI. We propose a five-point VI-RADS score, derived using T2-weighted MRI, diffusion-weighted imaging, and dynamic contrast enhancement, which suggests the risks of muscle invasion. We include sample images used to understand VI-RADS.
We hope that VI-RADS will standardize reporting, facilitate comparisons between patients, and in future years, will be tested and refined if necessary. While we do not advocate mpMRI for all patients with BC, this imaging may compliment pathology or reduce radiation-based imaging. Bladder mpMRI may be most useful in patients with non–muscle-invasive cancers, in expediting radical treatment or for determining response to bladder-sparing approaches.
Magnetic resonance imaging (MRI) scans for bladder cancer are becoming more common and may provide accurate information that helps improve patient care. Here, we describe a standardized reporting criterion for bladder MRI. This should improve communication between doctors and allow better comparisons between patients.

Bladder-sparing trimodality therapy (TMT) is an alternative to radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC), and biomarkers to inform therapy selection are needed.
To evaluate ...the prognostic value of immune and stromal signatures in MIBC treated with TMT.
We used a clinical-grade platform to perform transcriptome-wide gene expression profiling of primary tumors from 136 MIBC patients treated with TMT at a single institution. We observed 60 overall survival events at 5yr, and median follow-up time for patients without an event was 5.0yr (interquartile range 3.1, 5.0). Expression data from another cohort of 223 MIBC patients treated with neoadjuvant chemotherapy (NAC) and RC were also analyzed.
Molecular subtype, immune, and stromal signatures were evaluated for associations with disease-specific survival (DSS) and overall survival (OS) in TMT patients, and in patients treated with NAC and RC.
Gene expression profiling of TMT cases identified luminal (N=40), luminal-infiltrated (N=26), basal (N=54), and claudin-low (N=16) subtypes. Signatures of T-cell activation and interferon gamma signaling were associated with improved DSS in the TMT cohort (hazard ratio 0.30 0.14–0.65, p=0.002 for T cells), but not in the NAC and RC cohort. Conversely, a stromal signature was associated with worse DSS in the NAC and RC cohort (p=0.006), but not in the TMT cohort. This study is limited by its retrospective nature.
Higher immune infiltration in MIBC is associated with improved DSS after TMT, whereas higher stromal infiltration is associated with shorter DSS after NAC and RC. Additional studies should be conducted to determine whether gene expression profiling can predict treatment response.
We used gene expression profiling to study the association between tumor microenvironment and outcomes following bladder preservation therapy for invasive bladder cancer. We found that outcomes varied with immune and stromal signatures within the tumor. We conclude that gene expression profiling has potential to guide treatment decisions in bladder cancer.
Gene expression profiling of muscle-invasive bladder cancer reveals that immune infiltration is associated with improved disease-specific survival after bladder-sparing trimodality therapy, but not after radical cystectomy. Conversely, stromal infiltration is associated with worse outcomes after cystectomy, but not after trimodality therapy.
Health-related quality of life (QOL) has not been well-studied in survivors of muscle-invasive bladder cancer (MIBC). The present study compared long-term QOL in MIBC patients treated with radical ...cystectomy (RC) versus bladder-sparing trimodality therapy (TMT).
This cross-sectional bi-institutional study identified 226 patients with nonmetastatic cT2-cT4 MIBC, diagnosed in 1990 to 2011, who were eligible for RC and were disease free for ≥2 years. Six validated QOL instruments were administered: EuroQOL EQ-5D, European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Core Questionnaire and EORTC MIBC module, Expanded Prostate Cancer Index Composite bowel scale, Cancer Treatment and Perception Scale, and Impact of Cancer, version 2. Multivariable analyses of the mean QOL scores were conducted using propensity score matching.
The response rate was 77% (n=173). The median follow-up period was 5.6 years. Of the 173 patients, 64 received TMT and 109, RC. The median interval from diagnosis to questionnaire completion was 9 years after TMT and 7 years after RC (P=.009). No significant differences were found in age, gender, comorbidities, tobacco history, performance status, or tumor stage. On multivariable analysis, patients who received TMT had better general QOL by 9.7 points of 100 compared with those who had received RC (P=.001) and higher physical, role, social, emotional, and cognitive functioning by 6.6 to 9.9 points (P≤.04). TMT was associated with better bowel function by 4.5 points (P=.02) and fewer bowel symptoms by 2.7 to 7.1 points (P≤.05). The urinary symptom scores were similar. TMT was associated with better sexual function by 8.7 to 32.1 points (P≤.02) and body image by 14.8 points (P<.001). The patients who underwent TMT reported greater informed decision-making scores by 13.6 points (P=.01) and less concern about the negative effect of cancer by 6.8 points (P=.006). The study limitations included missing baseline QOL data and different follow-up times.
Both TMT and RC result in good long-term QOL outcomes in MIBC survivors, supporting TMT as a good alternative to RC for selected patients. Whether TMT leads to superior QOL requires prospective validation.
Abstract Background Despite its lethal potential, many patients with muscle-invasive bladder cancer (MIBC) do not receive aggressive, potentially curative therapy consistent with established practice ...standards. Objective To characterize the treatments received by patients with MIBC and analyze their use according to sociodemographic, clinical, pathologic, and facility measures. Design, setting, and participants Using the National Cancer Data Base, we analyzed 28 691 patients with MIBC (stages II–IV) treated between 2004 and 2008, excluding those with cT4b tumors or distant metastases. Treatments included radical or partial cystectomy with or without chemotherapy (CT), chemoradiotherapy (CRT), radiation therapy (RT), or CT alone and observation following biopsy. Aggressive therapy (AT) was defined as radical or partial cystectomy or definitive RT/CRT (total dose ≥50 Gy). Outcome measurements and statistical analysis AT use and correlating variables were assessed by multivariable, generalized estimating equation models adjusted for facility clustering. Results and limitations According to the database, 52.5% of patients received AT; 44.9% were treated surgically, 7.6% received definitive CRT or RT, and 25.9% of patients received observation only. AT use decreased with advancing age (odds ratio OR: 0.34 for age 81–90 yr vs ≤50 yr; p < 0.001). AT use was also lower in racial minorities (OR: 0.74 for black race; p < 0.001), the uninsured (OR: 0.73; p < 0.001), Medicaid-insured patients (OR: 0.81; p = 0.01), and at low-volume centers (OR: 0.64 vs high-volume centers; p < 0.001). Use of AT was higher with increasing tumor stage (OR: 2.23 for T3/T4a vs T2; p < 0.001) and nonurothelial histology (OR: 1.25 and 1.43 for squamous and adenocarcinoma, respectively; p < 0.001). Study limitations include retrospective design and lack of information about patient and provider motivations regarding therapy selection. Conclusions AT for MIBC appears underused, especially in the elderly and in groups with poor socioeconomic status. These data point to a significant unmet need to inform policy makers, payers, and physicians regarding appropriate therapies for MIBC.
Abstract Background Patterns of postoperative radiotherapy (RT) use in prostate cancer (PCa) after the publication of major randomized trials have not been well characterized. Objective To describe ...patterns of postoperative RT use after radical prostatectomy (RP) in patients with adverse pathologic features in the United States. Design, setting, and participants Retrospective analysis of 97 270 patients with PCa diagnosed between 2005 and 2011 whose presentation and outcomes were recorded in the National Cancer Data Base. Outcome measurements and statistical analysis Temporal changes in receipt of postoperative RT and factors associated with receipt of this treatment using the Cochran–Armitage trend test and multiple logistic regression, respectively. Results and limitations Between 2005 and 2011, receipt of postoperative RT decreased steadily from 9.1% to 7.3% ( ptrend < 0.001). Use of RT with or without androgen deprivation therapy monotonically decreased with advancing age from 8.5% in patients aged 18–59 yr to 6.8% in patients aged 70–79 yr ( ptrend < 0.001). Receipt of RT was higher at community cancer programs compared with teaching/research centers (14% vs 7.3%; odds ratio OR: 2.16; p < 0.001), in those with pT3-4 disease and positive margins compared with those with pT3-4 and negative margins (17% vs 5.9%; OR: 2.89; p < 0.001), and in patients with a Gleason score of 8–10 compared with those with a Gleason score of 2–6 (17% vs 4.2%; OR: 3.50; p < 0.001). Limitations include lack of postprostatectomy prostate-specific antigen level. Conclusions Postoperative RT use for localized PCa in patients with adverse pathologic features is declining in the United States. Patient summary In this report, we show that use of postoperative radiotherapy in patients with prostate cancer with adverse pathologic features is declining. Patients treated at community cancer programs, those with locally advanced disease and positive margins, and those with a high Gleason score were more likely to receive postoperative radiotherapy.
Abstract Background Numerous management options exist for patients with prostate cancer; however, recent trends and their influencing factors are not well described. Objective To describe modern ...patterns of care and factors associated with management choice using the National Cancer Database. Design, setting, and participants Patients with localized prostate cancer diagnosed between 2004 and 2012 were included and grouped according to National Comprehensive Cancer Network guidelines into low, intermediate, or high risk. Outcome measurements and statistical analysis Trend analyses and multivariate logistic regression was used to identify factors associated with management. Results and limitations There were 598 640 patients who met the study criteria; 36.3% were classified as low risk, 43.8% intermediate risk, and 20.0% high risk. Over the study period, among low-risk patients, observation increased from 9.2% to 21.3%, while radical prostatectomy (RP) increased from 29.5% to 51.1% ( p < 0.001 for both). In contrast, external beam radiotherapy decreased from 24.3% to 14.5%, while brachytherapy decreased from 31.7% to 11.1%. A similar pattern was seen for patients with intermediate-risk or high-risk disease. Among high-risk patients, RP increased from 25.1% to 43.4% replacing external beam radiotherapy as the dominant therapy. On multivariate analysis, racial minorities, the uninsured, and low-income patients were less likely to receive RP. Low-risk patients in similar subgroups were significantly more likely to be observed. Limitations include potential miscoding or misclassification of variables. Conclusions Patterns of care in localized prostate cancer are changing rapidly. While use of observation is increasing in low-risk groups, the use of RP is increasing across all risk groups with a concomitant decline in use of radiotherapy. Socioeconomic factors appear to influence management choice. Patient summary In this report we identify a recent significant increase in the use of radical prostatectomy for prostate cancer patients. Socioeconomic factors such as race, insurance type, and income may affect treatments offered to and received by patients.
