Toren P, Wilkins A, Patel K, Burley A, Gris T, Kockelbergh R, Lodhi T, Choudhury A, Bryan RT. The sex gap in bladder cancer survival - a missing link in bladder cancer care? Nat Rev Urol 2024; 21:181-192. [PMID: 37604983 DOI: 10.1038/s41585-023-00806-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/17/2023] [Indexed: 08/23/2023]
Abstract
The differences in bladder cancer outcomes between the sexes has again been highlighted. Uncommon among cancers, bladder cancer outcomes are notably worse for women than for men. Furthermore, bladder cancer is three to four times more common among men than among women. Factors that might explain these sex differences include understanding the importance of haematuria as a symptom of bladder cancer by both clinicians and patients, the resultant delays in diagnosis and referral of women with haematuria, and health-care access. Notably, these factors seem to have geographical variation and are not consistent across all health-care systems. Likewise, data relating to sex-specific treatment responses for patients with non-muscle-invasive or muscle-invasive bladder cancer are inconsistent. The influence of differences in the microbiome, bladder wall thickness and urine dwell times remain to be elucidated. The interplay of hormone signalling, gene expression, immunology and the tumour microenvironment remains complex but probably underpins the sexual dimorphism in disease incidence and stage and histology at presentation. The contribution of these biological phenomena to sex-specific outcome differences is probable, albeit potentially treatment-specific, and further understanding is required. Notwithstanding these aspects, we identify opportunities to harness biological differences to improve treatment outcomes, as well as areas of fundamental and translational research to pursue. At the level of policy and health-care delivery, improvements can be made across the domains of patient awareness, clinician education, referral pathways and guideline-based care. Together, we aim to highlight opportunities to close the sex gap in bladder cancer outcomes.

Abstract
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.

Abstract
Background Bladder cancer (BC) treatments are known to be invasive; nevertheless, research into the long-term effects is limited and in the context of sexual function often male focussed. Female sexual dysfunction (FSD) has been reported in up to 75% of female patients. This systematic scoping review examines the literature on sexual consequences of BC in female patients. Objective This study aimed to systematically evaluate the evidence on female sexual function in BC to identify areas of unmet need and research priorities. Evidence Acquisition We performed a critical review of PubMed, PsychMed, CINAHL, MEDLINE and the Cochrane Library in March 2020 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) extension for Scoping Reviews statement following Levac et al. methodology. Identified reports were reviewed according to the Critical Appraisal Skills Programme (CASP) criteria. 45 publications were included. Evidence Synthesis There was an inconsistent use of patient-reported outcome measures (PROMs), with commonly used PROMs having a narrow symptom focus. However, common symptoms emerged: loss of desire, orgasmic disorders, vaginal dryness, dyspareunia, difficult intromission, reduced clitoral sensation, psychological concerns related to diagnosis, fear of contamination and body image. Sexual activity was reduced in most groups, despite women expressing a motivation to retain sexual function. The degree of symptom distress associated with FSD is underreported. Evidence emerged regarding a gap for women in clinician counselling and follow-up. Conclusions The patient's perspective of FSD in BC patients is poorly understood and under-addressed in clinical practice. There have been very few qualitative studies of FSD in BC. Any intervention designed to address the problem must start with greater understanding of both the patients' and clinicians' perspective. Lay Summary We examined the evidence on sexual consequences of BC in women. It is apparent that despite common themes of sexual dysfunction emerging, the problem is poorly understood and addressed in clinical practice.

Abstract
PURPOSE To explore the gender differences in survival under different treatments in localized muscle-invasive bladder cancer (MIBC), and to find clinical strategies to improve the poor prognosis of female with bladder cancer (BC). METHODS Patients with localized MIBC were collected in the SEER database from 2010 to 2016 to analyze the gender differences in clinical characteristics. Propensity score matching was used to balance the effects of confounding factors. Kaplan-Meier method and Cox proportional hazards regression model were performed to compare the overall survival (OS) and cancer-specific survival (CSS) of patients between different treatment subgroups. RESULTS The entire cohort included 13,272 T2N0M0 MIBC patients, with a male-to-female incidence of 3:1. Compared with male patients, females had a higher age of onset and more blacks. There were more female patients undergoing bladder-sparing surgery (BSS) alone, and the OS and CSS were worse than those in males. The gender difference showed statistical significance in the BSS group, but not in the radical cystectomy (RC) group. CONCLUSION The survival of localized MIBC patients can be affected by treatments. Multi-modality treatment and RC may improve the survival prognosis of female patients.

Abstract
Radical cystectomy (RC) often affects patients’ life as this surgery is a traumatic and invasive event for the patients, with drawbacks on their daily, social, working, and sex life. Such changes in the quality of life (QoL) of patients are commonly studied through retrospective clinical evaluations and rarely with longitudinal studies. To date, studies focusing on functional outcomes, sexual function, and health-related QoL for female patients are lacking. We evaluated 37 patients using EORTC QLQ-C30 (QLQ-30) and Short-Form 36 (SF-36) questionnaires, before and after surgery, at 3 and 6 months of follow-up. The mean values for the emotional functioning in QLQ-C30 as well as the mental health in SF-36 were significantly higher in the ONB group compared to the IC group at 3 months of follow-up. These differences were not significant at 6 months of follow-up. At 6 months of follow-up, the ONB group showed a higher mean score in the physical and role functioning than the IC group. Although there was a statistically significant age difference at baseline of the two groups, none of the results are correlated with age, as demonstrated by Spearman’s analysis. The ONB seems to represent the most advantageous solution compared to the IC in terms of QOL at the 6-month follow-up.

Abstract
Complications associated with urinary bladder augmentation provide the motivation to delineate alternative bladder tissue regenerative engineering strategies. We describe the results of varying the proportion of bone marrow (BM) mesenchymal stem cells (MSCs) to CD34 + hematopoietic stem/progenitor cells (HSPCs) co-seeded onto synthetic POC [poly(1,8 octamethylene citrate)] or small intestinal submucosa (SIS) scaffolds and their contribution to bladder tissue regeneration. Human BM MSCs and CD34 + HSPCs were co-seeded onto POC or SIS scaffolds at cell ratios of 50 K CD34 + HSPCs/15 K MSCs (CD34-50/MSC15); 50 K CD34 + HSPCs/30 K MSCs (CD34-50/MSC30); 100 K CD34 + HSPCs/15 K MSCs (CD34-100/MSC15); and 100 K CD34 + HSPCs/30 K MSCs (CD34-100/MSC30), in male (M/POC; M/SIS; n = 6/cell seeded scaffold) and female (F/POC; F/SIS; n = 6/cell seeded scaffold) nude rats (n = 96 total animals). Explanted scaffold/composite augmented bladder tissue underwent quantitative morphometrics following histological staining taking into account the presence (S+) or absence (S−) of bladder stones. Urodynamic studies were also performed. Regarding regenerated tissue vascularization, an upward shift was detected for some higher seeded density groups including the CD34-100/MSC30 groups [F/POC S− CD34-100/MSC30 230.5 ± 12.4; F/POC S+ CD34-100/MSC30 245.6 ± 23.4; F/SIS S+ CD34-100/MSC30 278.1; F/SIS S− CD34-100/MSC30 187.4 ± 8.1; (vessels/mm2)]. Similarly, a potential trend toward increased levels of percent muscle (≥ 45% muscle) with higher seeding densities was observed for F/POC S− [CD34-50/MSC30 48.8 ± 2.2; CD34-100/MSC15 53.9 ± 2.8; CD34-100/MSC30 50.7 ± 1.7] and for F/SIS S− [CD34-100/MSC15 47.1 ± 1.6; CD34-100/MSC30 51.2 ± 2.3]. As a potential trend, higher MSC/CD34 + HSPCs cell seeding densities generally tended to increase levels of tissue vascularization and aided with bladder muscle growth. Data suggest that increasing cell seeding density has the potential to enhance bladder tissue regeneration in our model.

Abstract
CONTEXT Bladder cancer demonstrates striking gender-based differences in incidence, with a role for androgens possibly implicated in the development and progression of the disease. Emerging preclinical and clinical evidence suggests that there may be a role for antiandrogen therapy in bladder cancer. OBJECTIVE This systematic review assessed the current clinical evidence evaluating androgen suppressive therapy (AST) for the treatment or prevention of bladder cancer. EVIDENCE ACQUISITION Following Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, MEDLINE was searched for full-text articles detailing clinical outcomes or incidence of bladder cancer among patients who received AST, defined as gonadotropin-releasing hormone agonists or equivalent, androgen receptor antagonists, or 5-alpha reductase inhibitors. EVIDENCE SYNTHESIS A total of 12 studies were included. Five studies focused on prostate cancer patients, with one study in men with lower urinary tract symptoms. Among these studies, a lower incidence of bladder cancer was observed in five, with adjusted risk reduction estimates ranging from 7% to 47%. Six studies evaluating 11 820 bladder cancer patients investigated clinical outcomes among men who received a form of AST. Three out of four studies evaluating recurrence-free survival found a benefit for AST, with adjusted hazard ratios for recurrence of non-muscle-invasive cancer ranging from 0.29 to 0.53. Limitations included large variability in data sources and methodologies, as well as no data on tolerability. CONCLUSIONS Current evidence indicates that antiandrogen therapies exert a favorable influence on bladder tumors. Further prospective studies are needed to assess their therapeutic potential. PATIENT SUMMARY Androgen suppressive therapy is commonly prescribed for the treatment of prostate-related problems. Prior research indicates that there may be a role for these treatments in patients with bladder cancer. In this review, we evaluate the current evidence that strongly suggests that these agents may be effective against bladder cancer.

Abstract
Muscle-invasive bladder cancer (MIBC) is a sex-biased cancer with a higher incidence in men but worse outcomes in women. The root cause behind these observations remains unclear. To investigate whether sex-specific tumor biology could explain the differences in clinical behavior of MIBC, we analyzed the transcriptome profiles from transurethral resected bladder tumors of 1000 patients. Female tumors expressed higher levels of basal- and immune-associated genes, while male tumors expressed higher levels of luminal markers. Using molecular subtyping, we found that the rates of the basal/squamous subtype were higher in females than in males. Males were enriched with tumors of the luminal papillary (LumP) and neuroendocrine-like subtypes. Male MIBC tumors had higher androgen response activity across all luminal subtypes and male patients with LumP tumors were younger. Taken together, these data confirm differences in molecular subtypes based on sex. The role of the androgen response pathway in explaining subtype differences between men and women should be studied further. PATIENT SUMMARY: We explored the sex-specific biology of bladder cancer in 1000 patients and found that women had more aggressive cancer with higher immune activity. Men tended toward less aggressive tumors that showed male hormone signaling, suggesting that male hormones may influence the type of bladder cancer that a patient develops.
