Sex disparities in diagnosis of bladder cancer after initial presentation with hematuria: a nationwide claims-based investigation

"I think my vagina is still there?": Women's perspectives on sexual function and dysfunction following radical cystectomy for bladder cancer, a qualitative study

BACKGROUND

Women's sexual health after radical cystectomy is an important but poorly understood aspect of bladder cancer survivorship. Dedicated investigation is needed to elucidate patient perceptions on sexual function and dysfunction in this setting.

AIMS

In this study we sought to qualitatively examine women's perceptions and experiences of sexual health following radical cystectomy for bladder cancer.

METHODS

We conducted one-on-one qualitative telephone interviews with 40 women who underwent radical cystectomy in the past 6 months to 5 years and signed a research consent form to be contacted for future studies. We examined women's experiences of engaging in sexual activity after surgery and their attitudes toward sex and body image. We audio recorded, transcribed, and coded the interviews using ATLAS.ti software and applied grounded theory methods for analysis.

OUTCOMES

For data that emerged during the qualitative interviews that was related to lack of knowledge about how physical and psychological sexual health would be affected after surgery, we reviewed and discussed transcripts that enabled coding of the data into emerging topic areas.

RESULTS

Our analysis yielded 4 main themes. (1) Women reported receiving little to no information from providers about female sexual dysfunction prior to or after radical cystectomy. Women wished they had been provided more information about female sexual dysfunction from their clinicians, including strategies for postoperative self-pleasure and nonintercourse methods of sexual pleasure with partners. (2) Women shared that they were not sexually active following surgery due to physical and mental barriers. (3) When women did try to engage in sex, they described feeling disappointed that it did not feel the same as prior to surgery. (4) Some women found that physical therapy helped them to physically and mentally recover their strength to engage in sexual activity again.

CLINICAL IMPLICATIONS

Clinicians must directly address sexual health concerns with patients who undergo radical cystectomy.

STRENGTHS AND LIMITATIONS

This study has several key strengths. Investigation into women's sexual function and dysfunction addresses a gap in understanding of this component of women's health-related quality of life after radical cystectomy, which represents an unmet need. The large number of interviews conducted as well as the in-depth information obtained through one-on-one interviews are additional strengths. This study also has limitations, including possible shortcomings of telephone interviews compared with in-person interviews. However, telephone interviews were beneficial because the interviews took place during the COVID-19 pandemic and spared patients from extra visits or from having to travel long distances to the respective medical centers. Other possible limitations were that patients may have been reluctant to share all of their experiences and that patients who underwent urostomies, also termed ileal conduits, were overrepresented in this study compared with women who underwent continent urine diversions, which allow greater control over urine output.

CONCLUSION

Broadening the understanding of sexual health beyond sexual intercourse to encompass sexuality and self-pleasure can provide clinicians, patients, and their families with more effective preparation and strategies to care for an essential aspect of their wellbeing.

Clinical study of steroid receptors in nonmuscle invasive bladder cancer: A domain worth revisiting

Introduction

The prognostic significance of steroid receptors in bladder cancer remains controversial. This study was designed to determine the expression status of androgen receptor (AR), estrogen receptors (ERα and Erβ), and its potential role in predicting survival in patients with nonmuscle invasive bladder cancer (NMIBC).

Methods

Sixty patients of NMIBC were screened and 57 (41 males and 16 females) were included in our study. The tissue microarray slides were evaluated by pathologists blinded to the clinical information. Association of distribution of steroid receptors with stage, grade, progression, and recurrence was seen.

Results

The mean age of the population was 60.9 ± 9.3 years. Pathologically, majority of the patients were Ta (Ta: T1 stage 61.4% vs. 38.6%). Nine (15.8%) of the tumors stained positive for AR while one (1.8%) tumor stained positive for ERα and 36 (63.2%) tumors stained for ERβ. A higher proportion of male NMIBC stained positive for AR (19.5% vs. 6.2%, P = 0.420) while ERβ positivity was higher in females (58.5% vs. and 75%,P = 0.247). AR-negative tumors showed higher recurrence (20/48%-42%) as compared to AR-positive tumors (2/9%-22%). ERβ-positive tumors showed higher recurrence (15/36%-42% vs. 7/21%-33%, P = 0.179). Progression-free survival (PFS) was found to be significantly lower for ERβ-negative group (log-rank test P = 0.035).

Conclusion

AR and ERβ positivity is found in NMIBC patients while ERα shows minimal staining in NMIBC patients. Although it did not reach a statistical significance, a higher proportion of AR-negative and ERβ-positive tumors recurred as compared to AR-positive and ERβ-negative patients. PFS was significantly lower in ERβ-negative group. Further exploratory studies on larger sample sizes are required to validate these findings in NMIBC patients.

Sexual dimorphism in bladder cancer: a review of etiology, biology, diagnosis, and outcomes

European Association of Urology Guidelines on Muscle-invasive and Metastatic Bladder Cancer: Summary of the 2023 Guidelines

CONTEXT

We present an overview of the updated 2023 European Association of Urology (EAU) guidelines for muscle-invasive and metastatic bladder cancer (MMIBC).

OBJECTIVE

To provide practical evidence-based recommendations and consensus statements on the clinical management of MMIBC with a focus on diagnosis and treatment.

EVIDENCE ACQUISITION

A broad and comprehensive scoping exercise covering all areas of the MMIBC guidelines has been performed annually since 2017. Searches cover the Medline, EMBASE, and Cochrane Libraries databases for yearly guideline updates. A level of evidence and strength of recommendation are assigned. The evidence cutoff date for the 2023 MIBC guidelines was May 4, 2022.

EVIDENCE SYNTHESIS

Patients should be counselled regarding risk factors for bladder cancer. Pathologists should describe tumour and lymph nodes in detail, including the presence of histological subtypes. The importance of the presence or absence of urothelial carcinoma (UC) in the prostatic urethra is emphasised. Magnetic resonance imaging (MRI) of the bladder is superior to computed tomography (CT) for disease staging, specifically in differentiating T1 from T2 disease, and may lead to a change in treatment approach in patients at high risk of an invasive tumour. Imaging of the upper urinary tract, lymph nodes, and distant metastasis is performed with CT or MRI; the additional value of flurodeoxyglucose positron emission tomography/CT still needs to be determined. Frail and comorbid patients should be evaluated by a multidisciplinary team. Postoperative histology remains the most important prognostic variable, while circulating tumour DNA appears to be an interesting predictive marker. Neoadjuvant systemic therapy remains cisplatin-based. In motivated and selected women and men, sexual organ-preserving cystectomy results in better functional outcomes without compromising oncological outcomes. Robotic and open cystectomy have comparable outcomes and should be combined with (extended) lymph node dissection. The diversion type is an individual choice after taking patient and tumour characteristics into account. Radical cystectomy remains a highly complex procedure with considerable morbidity and risk of mortality, although lower rates are observed for higher hospital volumes (>20 cases/yr). With proper patient selection, trimodal therapy (chemoradiation) has comparable outcomes to radical cystectomy. Adjuvant chemotherapy after surgery improves disease-specific survival and overall survival (OS) in patients with high-risk disease who did not receive neoadjuvant treatment, and is strongly recommended. There is a weak recommendation for adjuvant nivolumab, as OS data are not yet available. Health-related quality of life should be assessed using validated questionnaires at baseline and after treatment. Surveillance is needed to monitor for recurrent cancer and functional outcomes. Recurrences detected on follow-up seem to have better prognosis than symptomatic recurrences.

CONCLUSIONS

This summary of the 2023 EAU guidelines provides updated information on the diagnosis and treatment of MMIBC for incorporation into clinical practice.

PATIENT SUMMARY

The European Association of Urology guidelines panel on muscle-invasive and metastatic bladder cancer has released an updated version of the guideline containing information on diagnosis and treatment of this disease. Recommendations are based on studies published up to May 4, 2022. Surgical removal of the bladder and bladder preservation are discussed, as well as updates on the use of chemotherapy and immunotherapy in localised and metastatic disease.

Pre-diagnostic prescription patterns in bladder and renal cancer: a longitudinal linked data study

BACKGROUND

Understanding pre-diagnostic prescribing activity could reveal windows during which more timely cancer investigation and detection may occur.

AIM

To examine prescription patterns for common urological clinical features prior to renal and bladder cancer diagnoses.

DESIGN AND SETTING

A retrospective cohort study was performed using electronic primary care and cancer registry data on patients with bladder and renal cancer, who received their diagnosis between April 2012 and December 2015 in England.

METHOD

Primary care prescriptions up to 2 years pre- diagnosis were analysed for five groups of clinical features (irritative urological symptoms, obstructive symptoms, urinary tract infections [UTIs], genital infections, and atrophic vaginitis). Poisson regressions estimating the inflection point from which the rate of prescriptions increased from baseline were used to identify the start of diagnostic windows during which cancer could be detected.

RESULTS

A total of 48 094 prescriptions for 5322 patients were analysed. Inflection points for an increase in UTI prescriptions were identified 9 months pre- diagnosis for renal (95% confidence interval [CI] = 5.3 to 12.7) and bladder (95% CI = 7.4 to 10.6) cancers. For bladder cancer, the change in UTI antibiotic prescription rates occurred 4 months earlier in females (11 months pre- diagnosis, 95% CI = 9.7 to 12.3) than in males (7 months pre-diagnosis, 95% CI = 5.4 to 8.6). For other clinical features, no inflection points were identified and, as such, no diagnostic windows could be defined.

CONCLUSION

Prescription rates for UTIs increased 9 months before bladder and renal cancer diagnoses, indicating that there is potential to expedite diagnosis of these cancers in patients presenting with features of UTI. The greatest opportunity for more timely diagnosis may be in females with bladder cancer, who experienced the earliest increase in UTI prescription rate.

Performance Characteristics of a Rule-Based Electronic Health Record Algorithm to Identify Patients with Gross and Microscopic Hematuria

BACKGROUND

Two million patients per year are referred to urologists for hematuria, or blood in the urine. The American Urological Association recently adopted a risk-stratified hematuria evaluation guideline to limit multi-phase computed tomography to individuals at highest risk of occult malignancy.

OBJECTIVES

To understand population-level hematuria evaluations, we developed an algorithm to accurately identify hematuria cases from electronic health records (EHRs).

METHODS

We used International Classification of Diseases (ICD)-9/ICD-10 diagnosis codes, urine color, and urine microscopy values to identify hematuria cases and to differentiate between gross and microscopic hematuria. Using an iterative process, we refined the ICD-9 algorithm on a gold standard, chart-reviewed cohort of 3,094 hematuria cases, and the ICD-10 algorithm on a 300 patient cohort. We applied the algorithm to Geisinger patients ≥35 years (n = 539,516) and determined performance by conducting chart review (n = 500).

RESULTS

After applying the hematuria algorithm, we identified 51,500 hematuria cases and 488,016 clean controls. Of the hematuria cases, 11,435 were categorized as gross, 26,658 as microscopic, 12,562 as indeterminate, and 845 were uncategorized. The positive predictive value (PPV) of identifying hematuria cases using the algorithm was 100% and the negative predictive value (NPV) was 99%. The gross hematuria algorithm had a PPV of 100% and NPV of 99%. The microscopic hematuria algorithm had lower PPV of 78% and NPV of 100%.

CONCLUSION

We developed an algorithm utilizing diagnosis codes and urine laboratory values to accurately identify hematuria and categorize as gross or microscopic in EHRs. Applying the algorithm will help researchers to understand patterns of care for this common condition.

Effects of gender and socio-environmental factors on health-care access in oncology: a comprehensive, nationwide study in France

Background

Gender-based disparities in health-care are common and can affect access to care. We aimed to investigate the impact of gender and socio-environmental indicators on health-care access in oncology in France.

Methods

Using the national health insurance system database in France, we identified patients (aged ≥18 years) who were diagnosed with solid invasive cancers between the 1st of January 2018 and the 31st of December 2019. We ensured that only incident cases were identified by excluding patients with an existing cancer diagnosis in 2016 and 2017; skin cancers other than melanoma were also excluded. We extracted 71 socio-environmental variables related to patients' living environment and divided these into eight categories: inaccessibility to public transport, economic deprivation, unemployment, gender-related wage disparities, social isolation, educational barriers, familial hardship, and insecurity. We employed a mixed linear regression model to assess the influence of age, comorbidities, and all eight socio-environmental indices on health-care access, while evaluating the interaction with gender. Health-care access was measured using absolute and relative cancer care expertise indexes.

Findings

In total, 594,372 patients were included: 290,658 (49%) women and 303,714 (51%) men. With the exception of unemployment, all socio-environmental indices, age, and comorbidities were inversely correlated with health-care access. However, notable interactions with gender were observed, with a stronger association between socio-environmental factors and health-care access in women than in men. In particular, inaccessibility to public transport (coefficient for absolute cancer care expertise index = -1.10 [-1.22, -0.99], p < 0.0001), familial hardship (-0.64 [-0.72, -0.55], p < 0.0001), social isolation (-0.38 [-0.46, -0.30], p < 0.0001), insecurity (-0.29 [-0.37, -0.21], p < 0.0001), and economic deprivation (-0.13 [-0.19, -0.07], p < 0.0001) had a strong negative impact on health-care access in women.

Interpretation

Access to cancer care is determined by a complex interplay of gender and various socio-environmental factors. While gender is a significant component, it operates within the context of multiple socio-environmental influences. Future work should focus on developing targeted interventions to address these multifaceted barriers and promote equitable health-care access for both genders.

Designing Digital Therapeutic Content Using Chronic Disease Data: A Focus on Improving Urinary Dysfunction

In recent years, advancements in information and communication technologies, including artificial intelligence, big data, virtual reality, and augmented reality, have driven substantial growth in the field of digital medical diagnosis and treatment, thereby enhancing quality of life. Beginning in the mid-2010s with the advent of digital healthcare applications, and further accelerated by the impact of coronavirus disease 2019, digital therapeutic products have profoundly influenced society. Nevertheless, the expansion of digital therapeutics has encountered challenges associated with regulatory hurdles, differentiation from general digital healthcare, and the necessity for trustworthiness, which have contributed to a slower rate of progress. This study proposes a 3P content model-encompassing pre-education, prediction/diagnosis/treatment, and postmanagement-to increase the trustworthiness of digital therapeutics. The design of the 3P content model includes a fundamental structure that establishes networks with healthcare institutions, aiming to increase the reliability of data utilization and to facilitate integration with medical decision support systems. For case development, the study introduces a prototype of a mobile application that utilizes chronic disease urinary dysfunction data, demonstrating the cyclical structure inherent in the 3P content model.

Gender and cystectomy for bladder cancer: A high-volume tertiary urologic care center experience

BACKGROUND

Differences have often been reported in the outcomes of bladder cancer (BC) patients according to gender.

OBJECTIVE

This study aims to provide data on patients undergoing radical cystectomy (RC) in a high-volume tertiary urologic center and to assess whether gender discrepancies do exist in terms of surgical options and clinical outcomes.

MATERIALS AND METHODS

Consecutive BC patients treated between 2016 and 2020 at a single center (Careggi University Hospital, Florence, Italy) were included in the study. The impact of gender on disease stage at diagnosis, overall survival (OS), and type of surgery was analyzed.

RESULTS

The study series comprised 447 patients (85 females and 362 males). At a median follow-up of 28.3 months (IQR: 33.5), OS was 52.6% and cancer-specific survival was 67.6%. Significant differences in OS emerged for age, acute myocardial infarction (AMI), Charlson Comorbidity Index (CCI), pT, and pN. OS rates were higher in patients undergoing robot-assisted surgery and in those receiving open orthotopic neobladder (ONB) (p = 0.0001). No statistically significant differences were found between male and female patients regarding surgical offer in any age group, surgical time, early postoperative complications, pathologic stage, and OS.

CONCLUSIONS

After adjustment for pathologic tumor stage and treatment modalities, female and male patients showed similar oncologic outcomes. Further studies should be undertaken to evaluate functional results in women subjected to RC.

Molecular Markers for Bladder Cancer Screening: An Insight into Bladder Cancer and FDA-Approved Biomarkers

Bladder cancer is one of the most financially burdensome cancers globally, from its diagnostic to its terminal stages. The impact it imposes on patients and the medical community is substantial, exacerbated by the absence of disease-specific characteristics and limited disease-free spans. Frequent recurrences, impacting nearly half of the diagnosed population, require frequent and invasive monitoring. Given the advancing comprehension of its etiology and attributes, bladder cancer is an appealing candidate for screening strategies. Cystoscopy is the current gold standard for bladder cancer detection, but it is invasive and has the potential for undesired complications and elevated costs. Although urine cytology is a supplementary tool in select instances, its efficacy is limited due to its restricted sensitivity, mainly when targeting low-grade tumors. Although most of these assays exhibit higher sensitivity than urine cytology, clinical guidelines do not currently incorporate them. Consequently, it is necessary to explore novel screening assays to identify distinctive alterations exclusive to bladder cancer. Thus, integrating potential molecular assays requires further investigation through more extensive validation studies. Within this article, we offer a comprehensive overview of the critical features of bladder cancer while conducting a thorough analysis of the FDA-approved assays designed to diagnose and monitor its recurrences.

GNRH family genes contributed to gender-specific disparity of bladder cancer prognosis through exerting opposite regulatory roles between males and females

PURPOSE

There is gender-specific disparity in bladder cancer (BlCa) prognosis. Female BlCa patients present with more advanced tumor and have higher risks of disease recurrence, progression, and mortality than males. Since gonadotropin-releasing hormone (GNRH) family genes were critical genes in gender-related biological activity and could be detected in BlCa specimens, this study aimed to explore potential roles of GNRH1 and GNRHR in gender disparity of BlCa.

METHODS

RNA-sequencing data from The Cancer Genome Atlas Bladder Urothelial Carcinoma dataset, IMvigor210 immunotherapy cohort and Cancer Cell Line Encyclopedia database were used to compare potential roles of GNRH1 and GNRHR in males and females, respectively. Gene set enrichment analysis was used to analyze the biological functions.

RESULTS

Males with higher GNRH1 and GNRHR have better overall survival (P < 0.05, HR < 1), while females with higher expression have a trend toward worse overall survival (P < 0.05, HR > 1). Gene set enrichment analysis identified GNRH1 and GNRHR exert opposite regulatory roles in myogenesis (M5909), interferon-α response (M5911), interferon-γ response (M5913), inflammatory response (M5932) and TNF-α signaling via NF-κβ (M5890) between males and females. The five functions are up-regulated in females (NES > 0), while down-regulated in males (NES < 0). GNRH1 in females was positively correlated with CD3D (R-value > 0 and P < 0.05), while GNRHR in males was negatively correlated with CD247, CD3D and CD3E (R-value < 0 and P < 0.05).

CONCLUSION

GNRH1 and GNRHR have opposite effects on overall survival in different genders, and exert opposite roles in immune-related functions between different genders, which could emerge as a contributor to gender disparity of BlCa prognosis.

Outcomes of Hematuria Evaluation by Advanced Practice Providers and Urologists

OBJECTIVE

To examine the quality and costs of care for patients evaluated for hematuria by urologic advanced practice providers (APPs) and urologists. The roles of APPs in urology are growing, but their clinical and financial outcomes compared to urologists are not well understood.

METHODS

We conducted a retrospective cohort study of commercially insured patients using data from 2014 to 2020. We included adult beneficiaries with a diagnosis code for hematuria and an initial outpatient evaluation and management visit with a urologic APP or urologist. We assessed receipt of cystoscopy procedure, imaging study, bladder biopsy procedure, and bladder cancer diagnosis within 6 months of the initial visit. Secondary outcomes included the time until each of these outcomes occurred and the out-of-pocket spending and total payments.

RESULTS

We identified 59,923 patients who were initially evaluated for hematuria. Visits with urologic nurse practitioners rather than urologists were associated with significantly lower odds of receiving cystoscopy procedures (odds ratio [OR] 0.93, 95% confidence interval [95% CI] 0.54-0.72, P < .001), imaging studies (OR 0.79, 95% CI 0.69-0.91, P < .001), and bladder biopsy procedures (OR 0.61, 95% CI 0.41-0.92, P = .02). Visits with urologic physician assistants were associated with 11% greater out-of-pocket payments (incident risk ratio 1.11, CI 1.01-1.22, P = .02) and 14% greater total payments (incident risk ratio 1.14, CI 1.04-1.25, P = .004).

CONCLUSION

There are clinical and financial differences in hematuria care delivered by urologic APPs and urologists. The incorporation of APPs into urologic care warrants further study, and specialty-specific training for APPs should be considered.

Improving the diagnostic process for patients with possible bladder and kidney cancer: a mixed-methods study to identify potential missed diagnostic opportunities

BACKGROUND

Patients with bladder and kidney cancer may experience diagnostic delays.

AIM

To identify patterns of suboptimal care and contributors of potential missed diagnostic opportunities (MDOs).

DESIGN AND SETTING

Prospective, mixed-methods study recruiting participants from nine general practices in Eastern England between June 2018 and October 2019.

METHOD

Patients with possible bladder and kidney cancer were identified using eligibility criteria based on National Institute for Health and Care Excellence (NICE) guidelines for suspected cancer. Primary care records were reviewed at recruitment and at 1 year for data on symptoms, tests, referrals, and diagnosis. Referral predictors were examined using logistic regression. Semi-structured interviews were undertaken with 15 patients to explore their experiences of the diagnostic process, and these were analysed thematically.

RESULTS

Participants (n = 940) were mostly female (n = 657, 69.9%), with a median age of 71 years (interquartile range 64-77 years). In total, 268 (28.5%) received a referral and 465 (48.5%) had a final diagnosis of urinary tract infection (UTI). There were 33 (3.5%) patients who were diagnosed with cancer, including prostate (n = 17), bladder (n = 7), and upper urothelial tract (n = 1) cancers. Among referred patients, those who had a final diagnosis of UTI had the longest time to referral (median 81.5 days). Only one-third of patients with recurrent UTIs were referred despite meeting NICE referral guidelines. Qualitative findings revealed barriers during the diagnostic process, including inadequate clinical examination, female patients given repeated antibiotics without clinical reviews, and suboptimal communication of test results to patients.

CONCLUSION

Older females with UTIs might be at increased risk of MDOs for cancer. Targeting barriers during the initial diagnostic assessment and follow-up might improve quality of diagnosis.

Urine cytology in patients with gender confirmation surgery and hormone therapy: evaluation of urine cytology performance in an underserved patient population

INTRODUCTION

There is a practice gap and educational need regarding urine cytology (UC) performance in patients with history of gender confirmation surgery (GCS) and/or hormone therapy (HT). This potentially impacts diagnostic accuracy in this medically underserved population. We report a methodology that identifies relevant cases and evaluates the performance of UC in this cohort.

MATERIALS AND METHODS

Two institutional pathology archives from 2000 to 2021 were searched using relevant keywords to identify UC specimens from patients with GCS and/or HT for this retrospective study. For each specimen, patient demographics, relevant clinical history, and history of HT and/or GCS were noted. Each case was blindly reviewed by a cytopathologist according to The Paris System.

RESULTS

A total of 32 UC specimens from 15 patients with history of GCS and/or HT were identified. There were 13 male to female and 2 female to male transgender patients. The original diagnosis was negative for high-grade urothelial carcinoma (NHGUC) in 24 of 32 (75%) and atypical urothelial cells (AUC) in 8 of 32 (25%) cases. The most common atypical features were irregular nuclear membranes and prominent small nucleoli in 7 of 8 (87.5%). Degenerative changes were present in 5 of 8 (62.5%). On re-review, with relevant clinical history, 100% of cases were re-classified as NHGUC.

CONCLUSIONS

The original diagnosis of AUC in these cases likely reflects reactive changes post GCS and/or HT. This cohort may be at risk of AUC overdiagnosis, particularly if the pathologist is unaware of this clinical history. Pathologists need to recognize reactive cytomorphologic changes in these patients. Further multi-institutional studies are warranted to expand knowledge about UC performance in these patients.

Global trends in the epidemiology of bladder cancer: challenges for public health and clinical practice

Bladder cancer is among the ten most common cancers globally, causes considerable morbidity and mortality and is, therefore, a substantial burden for health-care systems. The incidence of bladder cancer is affected by demographic trends, most notably population growth and ageing, as well as exposure to risk factors, especially tobacco smoking. Consequently, the incidence has not been stable throughout the world over time, nor will it be in the near future. Further primary prevention efforts are of the utmost importance to reduce the medical and financial burden of bladder cancer on populations and health-care systems. Simultaneously, less-invasive and lower-cost approaches for the diagnosis of both primary and recurrent bladder cancers are required to address challenges posed by the increasing shortage of health-care professionals and limited financial resources worldwide. In this regard, urinary biomarkers have demonstrated promising diagnostic accuracy and efficiency. Awareness of the risk factors and symptoms of bladder cancer should also be increased in society, particularly among health-care professionals and high-risk groups. Studies investigating the associations between lifestyle factors and bladder cancer outcomes are scarce and should be a research priority. In this Review, we outline global trends in bladder cancer incidence and mortality, and discuss the main risk factors influencing bladder cancer occurrence and outcomes. We then discuss the implications, challenges and opportunities of these epidemiological trends for public health and clinical practice.

The Effect of Sex on Disease Stage and Survival after Radical Cystectomy in Non-Urothelial Variant-Histology Bladder Cancer

BACKGROUND

Female sex in patients treated by radical cystectomy (RC) is associated with more advanced stage and worse survival. However, studies supporting these findings mostly or exclusively relied on urothelial carcinoma of the urinary bladder (UCUB) and did not address non-urothelial variant-histology bladder cancer (VH BCa). We hypothesized that female sex is associated with a more advanced stage and worse survival in VH BCa, similarly to that of UCUB.

MATERIALS AND METHODS

Within the SEER database (2004-2016), we identified patients aged ≥18 years, with histologically confirmed VH BCa, and treated with comprehensive RC. Logistic regression addressing the non-organ-confined (NOC) stage, as well as cumulative incidence plots and competing risks regression addressing CSM for females vs. males, were fitted. All analyses were repeated in stage-specific and VH-specific subgroups.

RESULTS

Overall, 1623 VH BCa patients treated with RC were identified. Of those, 38% were female. Adenocarcinoma (n = 331, 33%), neuroendocrine tumor (n = 304, 18%), and other VH (n = 317, 37%) were less frequent in females but not squamous cell carcinoma (n = 671, 51%). Across all VH subgroups, female patients had higher NOC rates than males did (68 vs. 58%, p < 0.001), and female sex was an independent predictor of NOC VH BCa (OR = 1.55, p = 0.0001). Overall, five-year cancer-specific mortality (CSM) were 43% for females vs. 34% for males (HR = 1.25, p = 0.02).

CONCLUSION

In VH BC patients treated with comprehensive RC, female sex is associated with a more advanced stage. Independently of stage, female sex also predisposes to higher CSM.

Assessment of the Ecological Association between Tobacco Smoking Exposure and Bladder Cancer Incidence over the Past Half-Century in the United States

BACKGROUND

Since tobacco smoking represents the most established risk factor for bladder cancer, we sought to assess the ecological association between tobacco smoking prevalence and bladder cancer incidence and to contrast it with lung cancer.

METHODS

The annual overall tobacco smoking prevalence rates were extracted from the Report of the Surgeon General and the Center for Disease Control between 1953 and 1983. The overall age-adjusted incidence rates for bladder and lung cancers were derived from the Surveillance, Epidemiology, and End Results database between 1983 and 2013 (30-year latency period). Weighted least square regression models were used to assess bladder and lung cancer incidence rate differences (IRD) related to trends in tobacco smoking prevalence. A Wald test was used to compare whether the prevalence of tobacco smoking, as an explanatory variable, differentially predicts bladder versus lung cancer incidence rates.

RESULTS

The associations between tobacco smoking prevalence and bladder cancer incidence were not significant in the overall (IRD = +0.04; 95%CI (-0.14; +0.22); p = 0.63), male (IRD = +0.07; 95%CI (-0.09; +0.23); p = 0.37), or female (IRD = +0.12; 95%CI (-0.01; +0.25); p = 0.06) populations. There was an association between tobacco smoking prevalence and lung cancer incidence in the overall (IRD: +3.55; 95%CI ( +3.09; +4.00); p < 0.001), male (IRD: +4.82; 95%CI (+4.44; +5.20); p < 0.001), and female (IRD: +3.55; 95%CI (+3.12; +3.99); p < 0.001) populations. The difference between the observed associations of tobacco smoking prevalence with bladder versus lung cancer incidence was also significant in all examined populations (p < 0.001).

CONCLUSIONS

Variations in tobacco smoking prevalence only partially explained the trends in the incidence of bladder cancer, indicating that its etiology is complex.

Diminishing the Gender-Related Disparity in Survival among Chemotherapy Pre-Treated Patients after Radical Cystectomy-A Multicenter Observational Study

There is a well-documented problem of inferior outcome of muscle-invasive bladder cancer (MIBC) after radical cystectomy (RC) in women. However, previous studies were conducted before neoadjuvant chemotherapy (NAC) was widely adopted to multidisciplinary management of MIBC. In our study, we assessed the gender-related difference in survival between patients who received NAC and those who underwent upfront RC, in two academic centers. This non-randomized, clinical follow-up study enrolled 1238 consecutive patients, out of whom 253 received NAC. We analyzed survival outcome of RC according to gender between NAC and non-NAC subgroups. We found that female gender was associated with inferior overall survival (OS), compared to males (HR, 1.234; 95%CI 1.046-1.447; p = 0.013) in the overall cohort and in non-NAC patients with ≥pT2 disease (HR, 1.220 95%CI 1.009-1.477; p = 0.041). However, no gender-specific difference was observed in patients exposed to NAC. The 5-year OS in NAC-exposed women in ≤pT1 and ≥pT2 disease, was 69.333% 95%CI (46.401-92.265) and 36.535% (13.134-59.936) respectively, compared to men 77.727% 95%CI (65.952-89.502) and 39.122% 95%CI (29.162-49.082), respectively. The receipt of NAC not only provides downstaging and prolongs patients' survival after radical treatment of MIBC but may also help to diminish the gender specific disparity.

Survival outcomes following treatment delays among patients with early-stage female cancers: a nationwide study

BACKGROUND

The coronavirus disease 2019 (COVID-19) severely hindered the timely receipt of health care for patients with cancer, especially female patients. Depression and anxiety were more pronounced in female patients than their male counterparts with cancer during treatment wait-time intervals. Herein, investigating the impact of treatment delays on the survival outcomes of female patients with early-stage cancers can enhance the rational and precise clinical decisions of physicians.

METHODS

We analyzed five types of cancers in women from the Surveillance, Epidemiology, and End Results (SEER) program between Jan 2010 and Dec 2015. Univariate and multivariate Cox regression analyses were used to determine the impacts of treatment delays on the overall survival (OS) and cancer-specific survival (CSS) of the patients.

RESULTS

A total of 241,661 females with early-stage cancer were analyzed (12,617 cases of non-small cell lung cancer (NSCLC), 166,051 cases of infiltrating breast cancer, 31,096 cases of differentiated thyroid cancer, 23,550 cases of colorectal cancer, and 8347 cases of cervical cancer). Worse OS rates were observed in patients with treatment delays ≥ 3 months in stage I NSCLC (_adjustedHazard ratio (HR) = 1.11, 95% Confidence Interval (CI): 1.01-1.23, p = 0.044) and stage I infiltrating breast cancer (_adjustedHR = 1.23, 95% CI 1.11-1.37, p < 0.001). When the treatment delay intervals were analyzed as continuous variables, similar results were observed in patients with stage I NSCLC (_adjustedHR = 1.04, 95% CI 1.01-1.06, p = 0.010) and in those with stage I breast cancer (_adjustedHR = 1.03, 95% CI 1.00-1.06, p = 0.029). However, treatment delays did not reduce the OS of patients with differentiated thyroid cancer, cervical cancer, or colorectal cancer in the early-stage. Only intermediate treatment delays impaired the CSS of patients with cervical cancer in stage I (_adjustedHR = 1.31, 95% CI 1.02-1.68, p = 0.032).

CONCLUSION

After adjusting for confounders, the prolonged time from diagnosis to the initiation of treatment (< 6 months) showed limited negative effects on the survival of most of the patients with early-stage female cancers. Whether our findings serve as evidence supporting the treatment deferral decisions of clinicians for patients with different cancers in resource-limited situations needs further validation.

Human centered design workshops as a meta-solution to diagnostic disparities

OBJECTIVES

Diagnostic errors - inaccurate or untimely diagnoses or failures to communicate diagnoses - are harmful and costly for patients and health systems. Diagnostic disparities occur when diagnostic errors are experienced at disproportionate rates by certain patient subgroups based, for example, on patients' age, sex/gender, or race/ethnicity. We aimed to develop and test the feasibility of a human centered design workshop series that engages diverse stakeholders to develop solutions for mitigating diagnostic disparities.

METHODS

We employed a series of human centered design workshops supplemented by semi-structured interviews and literature evidence scans. Co-creation sessions and rapid prototyping by patient, clinician, and researcher stakeholders were used to generate design challenges, solution concepts, and prototypes.

RESULTS

A series of four workshops attended by 25 unique participants was convened in 2019-2021. Workshops generated eight design challenges, envisioned 29 solutions, and formulated principles for developing solutions in an equitable, patient-centered manner. Workshops further resulted in the conceptualization of 37 solutions for addressing diagnostic disparities and prototypes for two of the solutions. Participants agreed that the workshop processes were replicable and could be implemented in other settings to allow stakeholders to generate context-specific solutions.

CONCLUSIONS

The incorporation of human centered design through a series of workshops promises to be a productive way of engaging patient-researcher stakeholders to mitigate and prevent further exacerbation of diagnostic disparities. Healthcare stakeholders can apply human centered design principles to guide thinking about improving diagnostic performance and to center diverse patients' needs and experiences when implementing quality and safety improvements.

Radical cystectomy and urinary diversion in women: techniques, outcomes, and challenges-a narrative review

Background and Objective

Standard radical cystectomy (RC) in women includes the removal of the bladder, urethra, uterus with the adnexa, and the anterior vaginal wall, thereby severely affecting the urinary, sexual, and reproductive system. To limit these detrimental effects, organ-sparing, including nerve-sparing approaches, have been developed. Health-related quality of life (HRQOL) and functional outcomes are, indeed, becoming increasingly central to the shared decision-making with the patient. The objectives of this narrative review are: (I) to review the current status of RC in women, including the use of different urinary diversions (UDs); (II) to discuss organ-sparing approaches and their impact on oncological and functional outcomes in women; (III) to discuss the impact of RC on HRQOL and sexual function in women.

Methods

We performed a non-systematic literature review of the available publications in the PubMed database.

Key Content and Findings

Over the past years, gender differences in oncological and functional outcomes after RC have received increased attention. According to the currently available literature, organ-sparing approaches can be safely performed in well-selected women without negatively impacting oncological outcomes. The orthotopic neobladder is feasible and oncologically safe in well-selected and informed women. The choice of the UD should be based on comprehensive counseling and the patient's comorbidities and preferences. There still is a lack of data on sexual recovery after the different surgical approaches aimed to mitigate sexual dysfunction in women undergoing RC.

Conclusions

Pre-and post-operative counseling and support of females undergoing RC regarding their expectations and experiences in terms of quality of life and functional and sexual outcomes are currently insufficient. Well-designed studies in this field are necessary to further improve outcomes of women treated with RC with an overarching aim to close the gender gap in managing women with bladder cancer.

Gender and Advanced Urothelial Cancer: Outcome, Efficacy and Toxicity following Chemotherapy

Background and Objectives: The incidence of urothelial cancer in males is higher than in females; however, females have a higher risk of recurrence and progression. The aim of our study was to report the effect of gender on the oncological outcome in advanced urothelial cancer. Materials and Methods: In our retrospective study, all patients had undergone primary surgical treatment for urothelial cancer and were affected by stage IV disease at the time of chemotherapy. Response to therapy and toxicity were evaluated. Subgroups were analyzed for tumour presentation, first- and second-line treatment response, progression-free survival (PFS) and overall survival (OS). Results. Seventy-five patients, 18 (24%) females and 57 (76%) males, were considered. Investigation into the distribution of individual characteristics according to gender revealed a significant difference only for smoking, with a prevalence of smokers in women (p = 0.029). At the end of follow-up, OS was higher in females (27.5% vs. 17.4%; p = 0.047). Smoking did not significantly influence OS (p = 0.055), while univariate Cox regression analysis confirmed that males had a higher risk of death (HR = 2.28, 95% CI 0.99–129 5.25), with borderline statistical significance (p = 0.053). Men showed higher PFS than women both after first-line (p = 0.051) and second-line chemotherapy (p = 0.018), with a lower risk of progression (HR = 0.29, 95% CI 0.10–0.86; p = 0.026). No differences were found between genders with regard to toxicity. Conclusions. In our series, PFS rates following first- and second-line therapies for advanced urothelial carcinoma confirmed that females have a greater risk of progression than males.

The Role of Adjuvant Single Postoperative Instillation of Gemcitabine for Non-Muscle-Invasive Bladder Cancer: A Systematic Review and Meta-Analysis

Bladder cancer is a heterogeneous disease with variable natural history. Non-muscle-invasive bladder cancer has a favorable prognosis following transurethral resection, but the optimal adjuvant chemotherapy plan is still in debate. The aim of this study was to evaluate the effect of the adjuvant intravesical administration of a single dose of gemcitabine in the outcome of this disease. For that purpose, we performed a systematic review and meta-analysis on available randomized control trials on MEDLINE, EMBASE, Cochrane, Scopus, and Google Scholar databases. Ultimately, two studies were included with a total number of 654 patients. The statistical analysis performed showed that a single post-operative intravesical dose of gemcitabine does not affect the recurrence rate of non-muscle-invasive bladder cancer compared to placebo. Therefore, this therapeutic strategy does not offer any significant improvement on the outcomes of the disease. Nonetheless, due to the plethora of available therapeutic agents and treatment strategies, further research is needed to establish the optimal treatment in this category of patients.

Sex differences in treatment patterns for non-advanced muscle-invasive bladder cancer: a descriptive analysis of 3484 patients of the Netherlands Cancer Registry

PURPOSE

Bladder cancer (BC) is a common malignancy with well-established differences in incidence, clinical manifestation and outcomes between men and women. It is unknown to what extent disparities in outcomes are influenced by differences in treatment approaches. This paper describes treatment patterns among men and women with muscle-invasive BC focusing on curative treatment (radical cystectomy or trimodal therapy).

METHODS

A retrospective population-based cohort study was performed with data from the Netherlands Cancer Registry. All patients newly diagnosed with muscle-invasive, non-advanced BC (MIBC, cT2-4a, N0/X, M0/X) in the years 2018, 2019 and 2020 were identified. Patient and tumor characteristics and initial treatment were compared between men and women with descriptive statistics and multivariable logistic regression analyses.

RESULTS

A total of 3484 patients were diagnosed with non-advanced MIBC in 2018-2020 in the Netherlands, of whom 28% were women. Women had higher T-stage and more often non-urothelial histology. Among all strata of clinical T-stage, women less often received treatment with curative intent (radical cystectomy [RC] or trimodality treatment). Among RC-treated patients, women more often received neoadjuvant treatment (except for cT4a disease). After adjustment for pre-treatment factors, odds ratios were indicative of women having lower probability of receiving curative treatment and RC specifically, and higher probability to receive NAC when treated with RC then men, although not statistically significant.

CONCLUSIONS

Considerable differences in treatment patterns between men and women with MIBC exist. A more considerate role of the patient's sex in treatment decisions could help decrease these differences and might mitigate disparities in outcomes.

Identifying opportunities for timely diagnosis of bladder and renal cancer via abnormal blood tests: a longitudinal linked data study

BACKGROUND

Understanding pre-diagnostic test use could reveal diagnostic windows where more timely evaluation for cancer may be indicated.

AIM

To examine pre-diagnostic patterns of results of abnormal blood tests in patients with bladder and renal cancer.

DESIGN AND SETTING

A retrospective cohort study using primary care and cancer registry data on patients with bladder and renal cancer who were diagnosed between April 2012 and December 2015 in England.

METHOD

The rates of patients with a first abnormal result in the year before cancer diagnosis, for 'generic' (full blood count components, inflammatory markers, and calcium) and 'organ-specific' blood tests (creatinine and liver function test components) that may lead to subsequent detection of incidental cancers, were examined. Poisson regression was used to detect the month during which the cohort's rate of each abnormal test started to increase from baseline. The proportion of patients with a test found in the first half of the diagnostic window was examined, as these 'early' tests might represent opportunities where further evaluation could be initiated.

RESULTS

Data from 4533 patients with bladder and renal cancer were analysed. The monthly rate of patients with a first abnormal test increased towards the time of cancer diagnosis. Abnormalities of both generic (for example, high inflammatory markers) and organ-specific tests (for example, high creatinine) started to increase from 6-8 months pre-diagnosis, with 25%-40% of these patients having an abnormal test in the 'early half' of the diagnostic window.

CONCLUSION

Population-level signals of bladder and renal cancer can be observed in abnormalities in commonly performed primary care blood tests up to 8 months before diagnosis, indicating the potential for earlier diagnosis in some patients.

Race, ethnicity, and gender reporting in North American clinical trials for BCG-unresponsive non-muscle invasive bladder cancer

INTRODUCTION

The National Institutes of Health (NIH) Revitalization Act of 1993 established guidelines for the inclusion of racial/ethnic minorities and women in clinical research. However, the reporting rate of such patient demographic data in clinical trials for BCG-unresponsive non-muscle invasive bladder cancer is not well characterized.

METHODS

We identified published clinical trials of all phases (I -III) for BCG-unresponsive non-muscle invasive bladder cancer conducted in the US and/or Canada. We calculated the proportion of studies reporting patient gender and race/ethnicity, tabulating these data when present. We compared reported trial participant race, ethnicity and gender with the number of new bladder cancer cases and deaths using the Centers for Disease Control and Prevention (CDC) and National Cancer Institute (NCI) U.S. Cancer Statistics data from 2013 -2017.

RESULTS

We identified 27 trials published from 1998 -2021 enrolling a total of 1673 patients. While all trials included data on patient gender (22% women overall), only 40.7% included any data on patient race/ethnicity. Among those that did, trial participants were reported as white (94%), Black (2.1%), Hispanic (0.6%), Asian (0.9%), and Other (2.3%). Racial/ethnic minorities were underrepresented in clinical trials relative to their proportion of new bladder cancer cases and deaths.

CONCLUSION

Most clinical trials that have been conducted for BCG-unresponsive non-muscle invasive bladder cancer do not report data on patient race or ethnicity despite NIH guidelines advocating for inclusion of such data. Racial/ethnic minorities remain underrepresented in these trials relative to the burden of bladder cancer prevalence and mortality faced by these groups.

The Impact of Race and Sex on Metastatic Bladder Cancer Survival

OBJECTIVE

To characterize the epidemiological profile of metastatic bladder cancer (BC) and assess mortality rate with respect to race and gender across the three most common histologies of bladder cancer-Transitional Cell Carcinoma, Adenocarcinoma, and SCC (Squamous Cell Carcinoma).

MATERIALS AND METHODS

The Surveillance, Epidemiology, and End Results Program database (2000-2017) was queried for all metastatic bladder cancer patients at presentation. Our primary exposure consists of four race/gender combinations. One-way ANOVA and Chi-square tests compared categorical and continuous variables across the exposure variable, respectively. Univariable and multivariable Cox proportional hazards regression analyses were used to examine the association between race/gender combinations and the overall and cancer specific survival adjusting for the other variables.

RESULTS

A total of 312,846 bladder cancer patients, 6337 with distant metastases and 11,446 with regional metastases were evaluated. Black female cancer specific survival in metastatic disease was disproportionally lower compared to all race/gender for Transitional Cell Carcinoma 4.3% (95% CI: 1.6-8.9), SCC 2.6% (95% CI: 0.2-11.8), and Adenocarcinoma 6.4% (0.4%-25%). In regional metastastatic disease, worse cancer specific mortality was associated with identifying as a Black Female (aHR 1.17, P = .023), SCC (aHR 1.8, P <.001), increasing age (aHR 1.3, P <.001), and poorly differentiated grade (aHR 2.01, P <.001).

CONCLUSION

Black females experience excess mortality in overall and cancer oncologic outcomes in metastatic BC. Our findings contribute to the body of research warranting examination of the impact of social determinants of health and provider decisions on BC survivorship and contribute to physician decision making in the treatment and surveillance of bladder cancer.

Microhematuria in Women: Prevalence of Malignancy and Risk Score Evaluation

OBJECTIVES

To (1) determine the prevalence of urologic malignancy in women evaluated for microhematuria (MH) in a large university-based urology practice, (2) describe clinical features shared by women with MH, and (3) evaluate a risk score for urologic malignancy in women with MH.

METHODS

A retrospective chart review identified women with MH evaluated by a large, university-based urology practice between 2010 and 2020. Clinical and demographic variables associated with their evaluation, referral pattern, appropriateness of referral and evaluation, workup completed, and resulting diagnoses were reported. Patterns of repeat evaluations were also described. Patients were stratified as low-, intermediate-, or high-risk according to AUA/SUFU recommended risk stratification.

RESULTS

4456 charts resulted from an initial query based on females with ICD-9 and ICD-10 codes for MH between 2010-2020. 1730 patients (95.5% referrals v. 4.5% established urology patients) met criteria for inclusion in the study, and 1350 underwent evaluation for MH at the practice. Over 30% of referrals were considered inappropriate. 13 patients were diagnosed with urologic malignancy, all of whom were classified as intermediate- or high-risk according to AUA/SUFU criteria. Over 10% of patients had at least 2 evaluations for MH, with only 1 malignancy discovered on repeat evaluation for persistent MH.

CONCLUSIONS

Inappropriate referrals for MH are common. Incidence of urologic malignancy is incredibly low among women evaluated for MH, but especially among those classified as low- and intermediate-risk by new guidelines. Repeat evaluations for persistent, stable MH appear low yield in detecting malignancy.

Does neoadjuvant chemotherapy diminish the sex disparity in bladder cancer survival after radical cystectomy?

INTRODUCTION

Sex-specific survival disparities for bladder cancer outcomes after radical cystectomy (RC) have been demonstrated in several studies. However, these studies predate the widespread adoption of neoadjuvant chemotherapy (NAC). We evaluated the differences in sex-specific survival between patients who received NAC with those who did not, using a contemporary national outcomes database.

METHODS

The National Cancer Data Base was queried from 2004 to 2015 to identify subjects who underwent RC. Kaplan-Meier method with log-rank test was performed to compare all-cause mortality between men and women at each pathologic (p) TNM stage group: T1-4N0, N+ and M+ disease. Associations for all-cause mortality were identified using an adjusted Cox regression analysis, and our findings were confirmed with a subgroup analysis.

RESULTS

A total of 9,835 subjects (7,483 men and 2,532 women) were included in the analysis. Kaplan-Meier survival curves and Cox regression analysis demonstrated female sex was not associated with worse overall survival compared to males (HR 0.947, 95%CI 0.852-1.053, P = 0.947) in the overall cohort. Stratified by pT stage and node positivity, worse overall survival was seen in women with pT4 disease who did not receive NAC compared to men (5-year OS 9.6% women vs. 15.2% men, P < 0.001), but no sex-specific difference was seen across all groups in patients who received NAC. Subgroup multivariable analysis showed that female sex conferred a survival disadvantage for pT4 (HR 1.369, P = 0.026) disease only in patients who did not receive NAC.

CONCLUSIONS

In a contemporary cohort of subjects who underwent RC, administration of NAC narrows the sex survival-gap in advanced stage bladder cancer. Strategies to improve NAC usage in women should be adopted to overcome potential sex-specific differences such as delayed diagnosis, anatomic differences in higher stage disease, or altered tumor biology which may contribute to differences in oncologic outcomes.

Differences in Quality of Life Between Men and Women who Undergo Bladder Preservation with Trimodality Therapy

PURPOSE: Sex-specific differences exist in muscle invasive bladder cancer (MIBC): men have a higher incidence; women present with more advanced disease; and surgical options differ between men and women. Health related quality of life (HRQoL) for male versus female patients with MIBC is not well understood and limited data exists in patients who undergo bladder preservation with trimodality therapy (TMT). The purpose of this study was to compare long-term HRQoL between men and women who have undergone TMT. METHODS AND MATERIALS: This was a secondary analysis of a prior study that reported long-term HRQoL differences for patients who underwent TMT. We analyzed patient reported HRQoL data to assess differences in HRQoL between men and women. RESULTS: Of the 64/74 (86%) TMT patients that completed questionnaires, 14 (22%) were women. Median age at diagnosis was 60 years for women and 66 years for men (p = 0.007). From six HRQoL instruments, there were two responses with a statistically significant difference between women and men –incidence of diarrhea and degree of sexual activity. Fifty percent of women compared to 86%of men reported no diarrhea (p = 0.02). A greater percentage of women reported some degree of sexual activity in the 4 weeks prior to questionnaire completion (p = 0.04), and sexual interest following TMT declined significantly with age in men, but not in women. CONCLUSIONS: In general, men and women report very good long-term HRQoL following TMT. There were, however, some differences between the sexes. Understanding this difference, especially related to sexual function, will allow more informed decision making by patients when choosing between treatment modalities.

Combination of AST to ALT and neutrophils to lymphocytes ratios as predictors of locally advanced disease in patients with bladder cancer subjected to radical cystectomy: Results from a single-institutional series

BACKGROUND

Bladder cancer (BC) staging is challenging. There is an important need for available and affordable predictors to assess, in combination with imaging, the presence of locally-advanced disease.

OBJECTIVE

To determine the role of the De Ritis ratio (DRR) and neutrophils to lymphocytes ratio (NLR) in the prediction of locally-advanced disease defined as the presence of extravescical extension (pT ⩾ 3) and/or lymph node metastases (LNM) in patients with BC treated with radical cystectomy (RC).

METHODS

We retrospectively analyzed clinical and pathological data of 139 consecutive patients who underwent RC at our institution. Logistic regression models (LRMs) were fitted to test the above-mentioned outcomes.

RESULTS

A total of 139 consecutive patients underwent RC at our institution. Eighty-six (61.9%) patients had a locally-advanced disease. NLR (2.53 and 3.07; p = 0.005) and DRR (1 and 1.17; p = 0.01) were significantly higher in patients with locally-advanced disease as compared to organ-confined disease. In multivariable LRMs, an increasing DRR was an independent predictor of locally-advanced disease (OR = 3.91; 95% CI: 1.282-11.916; p = 0.017). Similarly, an increasing NLR was independently related to presence of locally-advanced disease (OR = 1.28; 95% CI: 1.027-1.591; p = 0.028). In univariate LRMs, patients with DRR > 1.21 had a higher risk of locally advanced disease (OR = 2.83; 95% CI: 1.312-6.128; p = 0.008). Similarly, in patients with NLR > 3.47 there was an increased risk of locally advanced disease (OR = 3.02; 95% CI: 1.374-6.651; p = 0.006). In multivariable LRMs, a DRR > 1.21 was an independent predictor of locally advanced disease (OR = 2.66; 95% CI: 1.12-6.35; p = 0.027). Similarly, an NLR > 3.47 was independently related to presence of locally advanced disease (OR = 2.24; 95% CI: 0.95-5.25; p = 0.065). No other covariates such as gender, BMI, neoadjuvant chemotherapy or diabetes reached statistical significance. The AUC of the multivariate LRM to assess the risk of locally advanced disease was 0.707 (95% CI: 0.623-0.795). Limitations include the retrospective nature of the study and the relatively small sample size.

Breaking Barriers: Addressing Issues of Inequality in Trial Enrollment and Clinical Outcomes for Patients With Kidney and Bladder Cancer

Despite recent treatment advances, kidney and bladder cancer cases have continued to rise in both incidence and mortality over the last few decades. Not every demographic subgroup of patients diagnosed with these cancers has an equivalent outcome. Women diagnosed with bladder cancer have worse overall survival than men diagnosed with bladder cancer. Older adults with muscle-invasive bladder cancer have worse cancer-specific outcomes than do younger patients. Black patients diagnosed with kidney and bladder cancers appear to have worse overall survival than White patients diagnosed with these cancers. Although these differences in outcomes are likely multifactorial, in many cases they may be based on modifiable approaches to screening, diagnosing, and treating patients. We explore various causes of these differences in outcomes between patients and address patient engagement strategies and avenues to effect change. In 2021, equity in cancer and cancer care delivery has a more prominent place in the hierarchy of the continuum of medicine. Continued focus on this topic is critical, with clear accountabilities established and barriers to best care for patients eliminated.

Disparities in male versus female oncologic outcomes following bladder preservation: A population-based cohort study

Introduction

In surgical series of muscle‐invasive bladder cancer (MIBC), women have higher recurrence rates, disease progression, and mortality following radical cystectomy than men. Similar reports of oncologic differences between men and women following trimodality therapy (TMT) are rare. Our hypothesis was that there would be no difference in overall survival (OS) between sexes receiving TMT.

Methods

We queried the National Cancer Database (NCDB) for patients diagnosed with clinical stage T2‐T4aN0 M0 MIBC between 2004–2016. We considered patients to have received TMT if they received 55 Gy in 20 fractions or 59.4–70.2 Gy of radiotherapy with concurrent chemotherapy following a transurethral resection of bladder tumor (TURBT). We used multivariable Cox proportional hazard models to determine whether sex was associated with risk of mortality. In addition to OS, we calculated relative survival (RS) to adjust for the fact that females generally survive longer than males.

Results

Of the patients, 1960 underwent TMT and had survival data. Less than one quarter were female. In the first year following treatment, women had worse OS and RS than men (p = 0.093 and p = 0.030, respectively). However, overall and relative survival differences between sexes were not statistically significantly different in Years 2 and later. Unlike with OS, the RS between sexes remained significant at 9 years; in multivariable analysis based on RS, women were 43% more likely to die than men (p < 0.001).

Conclusions

Women had a higher initial risk of death than men in the first year following TMT. However, long‐term survival between sexes was similar. TMT is an important treatment option in both men and women seeking bladder preservation.

Evaluating Patient-Defined Priorities for Female Patients with Bladder Cancer

BACKGROUND: Although bladder cancer is much more common in men than in women, female patients with bladder cancer present with more locally advanced tumors and have worse disease-specific outcomes than male patients, even after controlling for biological differences. There is a paucity of research regarding the optimal approach to caring for female patients with bladder cancer in ways that maximize patient satisfaction, preferences, and values. OBJECTIVE: We sought to explore patient-defined priorities and areas in need of improvement for female patients with bladder cancer from the patient perspective. METHODS: We conducted focus group sessions and semi-structured interviews of women treated for bladder cancer to identify patient priorities and concerns until reaching topic saturation. Transcripts were analyzed thematically. RESULTS: Eight patients with muscle-invasive bladder cancer and six patients with non-muscle-invasive bladder cancer participated in two focus groups and seven interviews total. Three themes emerged as significantly affecting the care experience: physical impacts, mental health and emotional wellbeing, and the patient-provider interaction. Each theme included patient-defined specific recommendations on approaches to optimizing the care experience for women with bladder cancer. CONCLUSIONS: Although most participants were satisfied with the quality of care they received, they identified several opportunities for improvement. These concerns centered around enhancing support for patients’ physical and mental needs and strengthening the patient-provider interaction. Efforts to address these needs and reduce gender disparate outcomes via quality improvement initiatives are ongoing.

Prolonged Diagnostic Intervals as Marker of Missed Diagnostic Opportunities in Bladder and Kidney Cancer Patients with Alarm Features: A Longitudinal Linked Data Study

BACKGROUND

In England, patients who meet National Institute for Health and Care Excellence (NICE) guideline criteria for suspected cancer should receive a specialist assessment within 14 days. We examined how quickly bladder and kidney cancer patients who met fast-track referral criteria were actually diagnosed.

METHODS

We used linked primary care and cancer registration data on bladder and kidney cancer patients who met fast-track referral criteria and examined the time from their first presentation with alarm features to diagnosis. Using logistic regression we examined factors most likely to be associated with non-timely diagnosis (defined as intervals exceeding 90 days), adjusting for age, sex and cancer type, positing that such occurrences represent missed opportunity for timely referral, possibly due to sub-optimal guideline adherence.

RESULTS

28%, 42% and 31% of all urological cancer patients reported no, one or two or more relevant symptoms respectively in the year before diagnosis. Of the 2105 patients with alarm features warranting fast-track assessment, 1373 (65%) presented with unexplained haematuria, 382 (18%) with recurrent urinary tract infections (UTIs), 303 (14%) with visible haematuria, and 45 (2%) with an abdominal mass. 27% overall, and 24%, 45%, 18% and 27% of each group respectively, had a non-timely diagnosis. Presentation with recurrent UTI was associated with longest median diagnostic interval (median 83 days, IQR 43-151) and visible haematuria with the shortest (median 50 days, IQR 30-79). After adjustment, presentation with recurrent UTIs, being in the youngest or oldest age group, female sex, and diagnosis of kidney and upper tract urothelial cancer, were associated with greater odds of non-timely diagnosis.

CONCLUSION

More than a quarter of patients presenting with fast-track referral features did not achieve a timely diagnosis, suggesting inadequate guideline adherence for some patients. The findings highlight a substantial number of opportunities for expediting the diagnosis of patients with bladder or kidney cancers.

25-Year Trends in Stage-Specific Incidence Rates for Bladder Cancer in a Large Statewide Registry

BACKGROUND: Bladder cancer (BC) is a common genitourinary malignancy with over 80,000 new cases diagnosed annually and over 17,000 associated deaths. OBJECTIVE: We review 25-years of BC incidence (1993-2017) within the state of Pennsylvania to better define incidence, geographic distribution, and trends over time. METHODS: The Pennsylvania Cancer Registry was reviewed for statewide and component county age-adjusted BC incidence rates and stage distribution. Chloropleth maps plotting statewide and county-specific incidence rates across time were created using the GeoDa statistical package. RESULTS: 93,476 cases of BC were recorded in Pennsylvania from 1993 to 2017. Age-adjusted annual rates of BC over the study interval were stable at 24.5 patients per 100,000 (range, 22.7–25.6). However, annual rates of distant disease increased from 0.5 to 1.1 patients per 100,000 (p < 0.001) with an average percent change increase of 6.6% over the study interval. The annual percent distribution of distant disease doubled from 2.3% to 5.1% (p < 0.001) with a greater increase in women compared to men. Chloropleth maps highlighted growing “hot spots” of bladder cancer incidence in the northwestern, northeastern, and southeastern portions of the state. CONCLUSIONS: While BC incidence in the state of Pennsylvania has remained relatively stable over the past 25 years, a concerning increase in distant disease was observed. Geospatial investigation implicates higher risk regions. Further studies are necessary to delineate the underlying etiologies for these observations.

Gender discrepancies in bladder cancer: potential explanations

INTRODUCTION

Gender differences in urothelial carcinoma of the bladder (UCB) exist. Although men have a higher incidence of UCB, women tend to have poorer outcomes. We have explored and summarized the evidence for gender differences of UCB diagnosis and prognosis, together with reasons for these disparities.

The incidence of UCB is 3-4 times higher in men than women. However, women are more likely to be diagnosed with advanced disease. Women have a higher stage-for-stage mortality compared to men, and their greatest risk of death appears to be within the first 2 years of diagnosis. Survival outcomes following radical cystectomy (RC) and radiotherapy are also poorer in women. Delays in diagnosis, differences in female anatomy, as well as poorer surgical outcomes post-RC appear to contribute significantly to the disparities noted between genders. Other factors such as exposure to risk factors, differential hormone signaling, and carcinogen breakdown may also have a role.

EXPERT OPINION

The gender divide in UCB outcomes has to be addressed. Improved medical and patient education and centralization of RC are recommended.

Effect of pre-existing conditions on bladder cancer stage at diagnosis: a cohort study using electronic primary care records in the UK

Background

Pre-existing concurrent medical conditions (multimorbidity) complicate cancer diagnosis when they provide plausible diagnostic alternatives for cancer symptoms.

Aim

To investigate associations in bladder cancer between: first, pre-existing condition count and advanced-stage diagnosis; and, second, comorbidities that share symptoms with bladder cancer and advanced-stage diagnosis.

Design and setting

This observational UK cohort study was set in the Clinical Practice Research Datalink with Public Health England National Cancer Registration and Analysis Service linkage.

Method

Included participants were aged ≥40 years with an incident diagnosis of bladder cancer between 1 January 2000 and 31 December 2015, and primary care records of attendance for haematuria, dysuria, or abdominal mass in the year before diagnosis. Stage at diagnosis (stage 1 or 2 versus stage 3 or 4) was the outcome variable. Putative explanatory variables using logistic regression were examined, including patient-level count of pre-existing conditions and ‘alternative-explanations’, indicating whether pre-existing condition(s) were plausible diagnostic alternatives for the index cancer symptom.

Results

In total, 1468 patients (76.4% male) were studied, of which 399 (35.6%) males and 217 (62.5%) females had alternative explanations for their index cancer symptom, the most common being urinary tract infection with haematuria. Females were more likely than males to be diagnosed with advanced-stage cancer (adjusted odds ratio [aOR] 1.62; 95% confidence interval [CI] = 1.20 to 2.18; P = 0.001). Alternative explanations were strongly associated with advanced-stage diagnosis in both sexes (aOR 1.69; 95% CI = 1.20 to 2.39; P = 0.003).

Conclusion

Alternative explanations were associated with advanced-stage diagnosis of bladder cancer. Females were more likely than males to be diagnosed with advanced-stage disease, but the effect was not driven entirely by alternative explanations.

Clinical and therapeutic implications of sex steroid hormone receptor status in urothelial bladder cancer

Studies on the clinical profile of urothelial bladder cancer (UBC) have shown significant gender differences, namely, higher occurrence in males (male-to-female ratio of 3.5:1) and an advanced stage of disease at the time of diagnosis with rapid progression of the disease after initial diagnosis seen more commonly in females. The relationship between gender and UBC is complex and probably influenced by biological and epidemiological factors. Potential contributory factors such as sex steroid hormone pathway, gender difference in environmental carcinogen exposure, metabolic enzyme activity, and disparities in the intensity of diagnostic evaluation could probably explain the demographic trends in UBC. This comprehensive review of Medline publications during the period 2009–2019 attempts to identify the possible role of sex hormone receptors in gender variation and sexual dimorphism in the occurrence and progression of UBC. The clinical implications of identifying sex steroid receptors on factors such as disease prognostication and the therapeutic role of anti-androgens in the prevention and progression of UBC are critically reviewed. There is now significant evidence in literature to suggest the possible role of sex steroid hormone receptor-mediated signals in the genesis and progression of UBC. These receptors include androgen receptors, estrogen receptors, progesterone receptors, and various other orphan receptors. Excessive or reduced expression of these receptors, as well as alterations in their upstream or downstream pathways, correlate well with the clinical and therapeutic outcomes of UBC.

Diagnostic and treatment delays among patients with primary bladder cancer in Poland: a survey study

Introduction

The aim of this study was to determine and quantify the mechanisms responsible for the delays in bladder cancer diagnosis and initial treatment.

Material and methods

Patients referred to two academic hospitals in Poland with a primary bladder tumor were prospectively identified and structurally interviewed. For all patients, time intervals between symptom onset, diagnostic and therapeutic interventions were assessed.

Results

A total of 144 patients diagnosed with bladder cancer were included in the analysis. The median time from symptom onset to treatment was 112 days. This comprised of the following median waiting times: 1) patient waiting time of 13 days, 2) assessment waiting time of 14 days and 3) treatment waiting time of 42 days. In the multivariate analysis, large city residence (OR 0.2, 95% CI 0.1-0.6) and comorbidity (OR 0.3, 95% CI 0.1-0.8) reduced the risk of delay, whereas medium-sized city residence (OR 1.4, 95% CI 0.4-5.1) and general practitioner as the first medical professional contact (OR 5.3, 95% CI 0.6-50.0) increased the risk of delay.

Conclusions

Diagnostic and treatment waiting times for bladder cancer in Poland are unsatisfactory. Potential solutions for shortening these delays include healthcare policy changes such as utilization of the oncological priority programs, primary care education and public health campaigns.

Disparities in Bladder Cancer Outcomes Based on Key Sociodemographic Characteristics

PURPOSE OF REVIEW

A review of the impact of several key patient characteristics on oncologic outcomes in bladder cancer (BC) summarized and analyzed in a narrative fashion.

RECENT FINDINGS

The bulk of the published literature suggests that females and blacks have poorer cancer-specific outcomes. Both groups tend to present with worse disease, which may be driven by differences in access to timely and quality care. Attempts to assess the association between smoking status and history and BC outcomes have been hindered by the quality and heterogeneity of the data, although several studies have linked smoking with higher rates of recurrence and poorer survival. Being married, particularly in men, may improve survival after radical cystectomy (RC). Limited data suggests that socioeconomic and education levels may be associated with poorer survival; however, the data is limited. A growing body of investigation suggests that there are significant differences in oncologic outcomes in BC patients based on race, gender, smoking status, socioeconomic status, and others. Further focus and investigation is needed to validate these findings, investigate the root cause of these differences, and offer solutions to mitigate them.

Clear Cell Adenocarcinoma of the Urinary Bladder Is a Glycogen-Rich Tumor with Poorer Prognosis

Clear cell adenocarcinoma (CCA) is a rare variant of urinary bladder carcinoma with a glycogen-rich phenotype and unknown prognosis. Using the National Cancer Institute's surveillance, epidemiology, and end results (SEER) program database, we documented recent trends in incidence, mortality, demographical characteristics, and survival on this rare subtype of urinary bladder cancer. The overall age-adjusted incidence and mortality of CCA was 0.087 (95% confidence interval (CI): 0.069-0.107) and 0.064 (95% CI: 0.049-0.081) respectively per million population. In comparison to non-CCAs, CCAs were more commonly associated with younger age (<60 years old, p = 0.005), female (p < 0.001), black ethnicity (p = 0.001), grade III (p < 0.001), and higher AJCC 6th staging (p < 0.001). In addition, CCA patients more frequently received complete cystectomy (p < 0.001) and beam radiation (p < 0.001) than non-CCA patients. Our study showed a poorer prognosis of CCAs compared to all other carcinomas of the urinary bladder (p < 0.001), accounted for by higher tumor staging of CCA cases. This study adds to the growing evidence that glycogen-rich cancers may have unique characteristics affecting tumor aggressiveness and patient prognosis. Additional mechanistic studies are needed to assess whether it's the excess glycogen that contributes to the higher stage at diagnosis.

Sex and the Diagnostic Pathway to Bladder Cancer among Veterans: No Evidence of Disparity

BACKGROUND

Longer time intervals from presentation with hematuria to bladder cancer diagnosis have been reported among women compared with men. Despite women being the fastest growing cohort within the Department of Veterans Affairs, little is known about women veterans with bladder cancer. Our objectives were to quantify the time from hematuria to bladder cancer diagnosis in Department of Veterans Affairs and assess differences between sexes.

METHODS

This was a retrospective cohort study of patients diagnosed with bladder cancer from 2001 to 2016. Included were patients with hematuria for fewer than 365 days before a bladder cancer diagnosis and who had a record of diagnostic cystoscopy after hematuria but before diagnosis. We evaluated the number of days from hematuria to diagnostic cystoscopy (clinical appraisal), cystoscopy to bladder cancer diagnosis (surgical appraisal), and hematuria to bladder cancer diagnosis (total diagnostic appraisal). We used quantile regression models to separately evaluate the effect of sex on the three appraisal intervals.

RESULTS

Data from 213 women and 24,295 men were analyzed. The median clinical appraisal time was 78 days for women and 72 for men (p = .49). The median surgical appraisal time was 32 days for women and 33 for men (p = .74). The median total diagnostic appraisal time was 135 days for women and 130 for men (p = .71). Multivariable analyses showed no differences between men and women for any of the three appraisal intervals.

CONCLUSIONS

The majority of time from hematuria to bladder cancer diagnosis is spent in clinical appraisal, but little difference was observed between men and women in Department of Veterans Affairs.
