Female Sexual Function Following Radical Cystectomy in Bladder Cancer

Sex Disparities in Bladder Cancer Diagnosis and Treatment

Gender differences in prevalence, tumor invasiveness, response to treatment, and clinical outcomes exist in different types of cancer. The aim of this article is to summarize the sex disparities in bladder cancer diagnosis and treatment and try to suggest areas for improvement. Although men are at a higher risk of developing bladder tumors, women tend to be diagnosed with more advanced stages at diagnosis and are more likely to present with upfront muscle-invasive disease. Non-urothelial histological subtypes are more frequently reported in women. Regarding non-muscle-invasive bladder cancer (NMIBC), several studies have shown that women have a higher risk of disease recurrence after treatment with Bacillus Calmette-Guerin, due to different immunogenicities. In localized muscle-invasive bladder cancer (MIBC), neoadjuvant chemotherapy and cystectomy are less likely to be performed on women and sexual-sparing procedures with neobladder diversion are rarely offered. Finally, women appear to have a poorer prognosis than men, potentially due to the sex-associated intrinsic features of hosts and tumors that may drive differential therapeutic responses, particularly to immune-based therapies. Women are also more likely to develop severe adverse events related to systemic therapies and are underrepresented in randomized studies, leading to a gap between the real world and trials. In conclusion, studies investigating the role of sex and gender are urgently needed to improve the management of urothelial carcinoma.

Multidisciplinary management of sexual and gender minorities with bladder cancer

Bladder cancer, a common urologic malignancy, has poor morbidity and mortality in sexual and gender minority (SGM) individuals, stemming from higher risk, poor access to care and lack of quality cancer care. To begin addressing this disparity, this review offers key considerations for evaluation, diagnosis and treatment of SGM individuals with bladder cancer. In addition to thorough medical and surgical history, initial evaluation should include discussion of patient goals for sexual function and organ preservation, as well as an evaluation of sexual function. Prior gender affirming surgery and patient specific sexual function goals will impact diagnosis and treatment approaches, including surgical and radiation therapy. Throughout care for SGM individuals with bladder cancer, it is critical to acknowledge the systemic discrimination that may be experienced by these individuals and approach conversations with sensitivity and humility and incorporate mental and social support as appropriate.

Oncologic outcomes of pelvic organ-preserving radical cystectomy vs. Standard radical cystectomy: A systematic review and meta-analysis

BACKGROUND AND OBJECTIVE

Radical Cystectomy is indicated in muscle-invasive bladder cancer and select cases of nonmuscle invasive bladder cancer. Women often undergo additional reproductive organ removal, greatly impacting sexual function and quality of life. Pelvic organ-preserving radical cystectomy aims to mitigate these effects, but its oncologic outcomes are not well-defined. This presents a meta-analysis of available literature on oncological outcomes of pelvic organ-preserving radical cystectomy in women with muscle invasive disease.

METHODS

A systematic search across PubMed, Web of Science, Scopus, and Google Scholar was performed to identify studies comparing oncological outcomes between pelvic organ-preserving radical cystectomy and standard radical cystectomy in women with muscle-invasive bladder cancer or high-risk or recurrent nonmuscle invasive cancer. The search included English or Spanish studies, statistically comparing overall survival, cancer-specific survival, and recurrence-free survival. Statistical analysis used Review Manager, employing fixed or random-effects models based on heterogeneity.

KEY FINDINGS AND LIMITATIONS

Six retrospective studies met inclusion criteria, totaling 597 patients of which 303 received pelvic organ-preserving radical cystectomy and 294 received standard radical cystectomy. Overall Survival was not different between the 2 groups (HR 1.05 [0.77, 1.43]; P = 0.77). Cancer-Specific Survival also was found to be not different between the 2 groups (HR 1.27 [0.86, 1.87]; P = 0.22). Additionally, recurrence-free survival was not different between the 2 groups (HR 0.85 [0.41, 1.75]; P = 0.65. Four of the included studies exhibited a moderate risk of bias, with 1 study demonstrating low risk and the remaining study manifesting a serious risk of bias.

CONCLUSION

The comparison showed no significant differences in overall survival, cancer-specific survival, or recurrence-free survival rates.

Association between bladder cancer treatment and female sexual function

INTRODUCTION

Bladder cancer ranks 17th in prevalence of cancer types among women, and the trend is rising. The increased risk of female sexual dysfunction (FSD) after radical cystectomy (RC) underscores the need for greater focus on preserving and mitigating FSD.

OBJECTIVES

To place greater emphasis on the importance of female sexual function (FSF) in the treatment of bladder cancer and stimulate additional research to discover more effective solutions for enhancing the overall quality of life.

METHODS

This review used a narrative approach. Previous reviews on FSF after RC have provided limited and 1-sided solutions due to the lack of research. What makes this review unique is its innovative approach: it includes all available measures curing FSD as well as comparative analyses based on experimental data, thus making the findings more comprehensive. A detailed perspective of treatments for female bladder cancer is provided, including nerve- and organ-sparing RC, robot-assisted RC, and radiotherapy. We also analyze the impact of treatments for female bladder cancer on postoperative FSD. Additionally, solutions for addressing or alleviating postoperative FSD are summarized, such as urinary diversion, vaginal reconstruction, and drug and nondrug treatment.

RESULTS

Research has suggested that robot-assisted nerve- and organ-sparing RC is promising. Moreover, orthotopic neobladder among urinary diversions without a stoma helps to maintain a positive female body image. If part of the anterior vaginal wall must be removed during RC, vaginal reconstruction can restore the dimensions with synthetic grafts and biologic scaffolds. Additionally, postoperative measures, such as vaginal laser and hormone therapy, and use of vaginal dilators and lubricants have a significant role in reducing distress caused by FSD to provide maximum relief.

CONCLUSIONS

To support FSF after RC, various interventions are needed, and urologists must focus on patient recovery while minimizing treatment impact on FSF as much as possible.

Comparative evaluation of reproductive organ-preserving versus standard radical cystectomy in female: a meta-analysis and systematic review of perioperative, oncological, and functional outcomes

BACKGROUND

To evaluate the perioperative, oncological, and functional outcomes of reproductive organ-preserving radical cystectomy (ROPRC) compared to standard radical cystectomy (SRC) in the treatment of female bladder cancer.

METHODS

A systematic search was conducted in November 2023 across several scientific databases. We executed a systematic review and cumulative meta-analysis of the primary outcomes of interest, adhering to the PRISMA and AMSTAR guidelines. The study was registered in PROSPERO (CRD42024501522).

RESULTS

The meta-analysis included 10 studies with a total of 2015 participants. ROPRC showed a significant reduction in operative time and postoperative fasting period compared to SRC (MD - 45.69, 95% CI - 78.91 ~ - 12.47, p = 0.007, and MD - 0.69, 95% CI - 1.25 ~ - 0.13, p = 0.02, respectively). Functional outcomes, both daytime continence rate (OR 4.94, 95% CI 1.53 ~ 15.91, p = 0.008) and nighttime continence rate (OR 5.91, 95% CI 1.94 ~ 18.01, p = 0.002), and sexual function measured by the Female Sexual Function Index (MD 5.72, 95% CI 0.19 ~ 11.26, p = 0.04), were significantly improved in the ROPRC group. There were no significant differences between ROPRC and SRC in terms of estimated blood loss, length of hospital stay, overall postoperative complications, minor complications or major complications. Oncologically, both procedures showed comparable outcomes with no significant differences in positive surgical margins, tumor recurrence rates, overall survival, cancer-specific survival, recurrence-free survival, or progression-free survival.

CONCLUSIONS

ROPRC is a viable and effective alternative to SRC in female bladder cancer patients, offering enhanced functional outcomes and similar oncological safety. These findings suggest that ROPRC can improve the quality of life in female bladder cancer patients without compromising the efficacy of cancer treatment.

Radical cystectomy in the female patient: The pelvic floor, sexual function, and patient/provider education

Radical cystectomy in women results in numerous deleterious anatomic impacts to the pelvic floor that can result in sexual dysfunction, pelvic organ prolapse, and other disorders of pelvic floor function. A comprehensive understanding of this relationship and the quality-of-life impacts of radical cystectomy in women is important. This narrative review provides an overview of female pelvic floor disorders in the setting of radical cystectomy, with focus on present understanding of related anatomy, incidence, and prevention strategies, as well as the importance of both provider and patient education.

Population Estimates of Ovarian Cancer Risk in a Cohort of Patients with Bladder Cancer

BACKGROUND AND OBJECTIVE

The rationale for oophorectomy during female cystectomy is not adequately supported. The co-occurrence and timing of bladder cancer (BC) and ovarian cancer (OC) in females harboring OC germline mutations remain unclear. Our objective was to determine the frequency and temporal occurrence of OC germline variants among females with BC.

METHODS

We used genetic and phenotypic data from the UK Biobank (UKB). The study cohort was defined using ICD-10/ICD-9 codes for BC and further stratified to identify 1347 females. Analysis was restricted to variants with high/moderate impact for initial regression. ClinVar was used to interpret pathogenicity. Pathogenic/likely pathogenic (P/LP) variants were assessed by age of presentation, family history, and concomitant malignancies. Statistical analysis was performed using UKB DNAnexus JupyterLab and RStudio.

KEY FINDINGS AND LIMITATIONS

Some 3.4% of the patients had at least one of 15 variants for OC. CHEK2 and PALB2 mutations represented the highest ratio of overall/pathogenic variants (15.8% and 6.6%). Although females with P/LP OC mutations had a higher risk of OC, diagnosis of OC preceded BC by 11.3 yr (±12.5 yr) in the group with mutations and by 15.6 yr (±11.3 yr) in the group without mutations. The group with P/LP variants had higher rates of maternal (14.63% vs 8.12%; p = 0.04) and sibling (9.76% vs 3.98%; p = 0.02) breast cancer and of maternal colon cancer (9.76% vs 4.21%), and lower maternal life expectancy (75.34 vs 68.15 yr; p = 0.0014). UKB provides limited staging/treatment history and its exome sequencing platform may miss variants or provide insufficient coverage for genotyping.

CONCLUSIONS AND CLINICAL IMPLICATIONS

This study provides evidence against routine oophorectomy for reducing OC risk in females with BC. The results highlight that the development of OC occurred 11 yr before diagnosis of BC for patients with OC mutations and 15 yr before diagnosis of BC for patients without OC mutations.

PATIENT SUMMARY

Although removal of the ovaries in women with bladder cancer is common, no studies have shown that this strategy has a benefit. Our study of women diagnosed with bladder cancer who had genetic mutations associated with ovarian cancer shows that their risk of developing ovarian cancer after bladder cancer is low. These findings provide evidence against removal of the ovaries when the bladder is being removed as treatment for bladder cancer.

Evaluation of sexual function and vaginal prolapse after radical cystectomy in women: a study to explore an under-evaluated problem

INTRODUCTION AND HYPOTHESIS

The objective was to evaluate sexual function, vaginal prolapse, and quality of life (QoL) in women after radical cystectomy (RC) using validated questionnaires and pelvic organ prolapse quantification (POP-Q) measurement.

METHODS

Female bladder cancer patients who underwent RC at our tertiary care center were included (January 2008 to March 2022). Patients received three validated questionnaires (International Consultation on Incontinence Questionnaire Vaginal Symptoms [ICIQ-VS] Part A, Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire IUGA revised [PISQ], European Organization for Research and Treatment of Cancer Quality of Life Questionnaire [EORTC] C30/BLM30). Patients who consented were examined with vaginal POP-Q measurement.

RESULTS

Out of 322 patients, 193 were still alive, 54 patients were lost to follow-up, and 43 were excluded, resulting in 96 patients who received the questionnaire. Finally, 35 patients were included, of whom 17 patients consented to vaginal examination. Complaints due to vaginal symptoms were low (ICIQ-VS 6.17 + 5.37). Sexual activity was reported by 12 patients (34.3%); 23 patients (65.71%) were not sexually active. No apical prolapse was found in POP-Q measurement; 6 patients (35.3%) had anterior, and 14 patients (82.4%) posterior prolapse; the highest prolapse stage was 2. No significant differences were found regarding POP stages, sexual function, and QoL (all p > 0.05) when comparing continent and incontinent urinary diversions. Comparing the vaginal approach (no sparing vs sparing), significant differences were found in only two PISQ subscales (significantly higher scores after vagina sparing, p = 0.01 and p = 0.02).

CONCLUSIONS

The type of urinary diversion, POP-Q stages, and tumor stages did not show significant differences regarding sexual function, QoL, and prolapse complaints in women after RC, whereas a vagina- sparing approach showed significant differences only in two subscales without clinical relevance.

Long-term survival after female pelvic organ-sparing radical cystectomy versus standard radical cystectomy: a multi-institutional propensity score-matched analysis

BACKGROUND

The application of pelvic organ preserving-radical cystectomy (POPRC) in female patients with bladder cancer has attracted more and more attention in recent years. In the current study, the authors aim to compare the long-term oncological outcomes of POPRC versus standard radical cystectomy (SRC) in a large multicenter retrospective cohort.

PATIENTS AND METHODS

Data on female patients with bladder cancer who underwent POPRC or SRC in January 2006 and April 2018 were included from three Chinese urological centers. The primary outcome was overall survival (OS). Secondary outcomes were cancer-specific survival and recurrence-free survival. To decrease the effect of unmeasured confounders associated with treatment selection, 1:1 propensity score matching was performed.

RESULTS

Among the 273 enrolled patients, 158 underwent POPRC (57.9%), and 115 underwent SRC (42.1%). The median follow-up time was 38.6 (15.9-62.5) months. After propensity score matching, each cohort included 99 matched patients. The OS ( P =0.940), cancer-specific survival ( P =0.957), and recurrence-free survival ( P =0.476) did not differ significantly from the two matched cohorts. Subgroup analysis confirmed that the OS was similar between the patients treated with POPRC and SRC across all subgroups examined (all P > 0.05). In multivariable analysis, the surgical method (SRC vs. POPRC) was not an independent risk factor for OS (Hazard ratio 0.874, 95% CI 0.592-1.290; P =0.498).

CONCLUSIONS

The results showed that no significant difference in long-term survival was determined between female patients undergoing SRC and those undergoing POPRC.

Female sexual function evaluation and intraoperative vaginal reconstruction in bladder cancer

RC significantly negatively impacts sexual function (SF) in both men and women. While significant research resources have been allocated to examine the deleterious effects of post prostatectomy erectile dysfunction, little attention has been directed towards female sexual function and organ preservation post cystectomy. These academic shortcomings often result in poor provider awareness and inadequate preoperative assessment. As such, it is crucial for all providers involved in female RC care to understand the necessary and available tools for preoperative evaluation, in addition to the anatomic and reconstructive techniques. This review aims to summarize the current preoperative evaluation and available tools of SF assessment and describe in detail the varying operative techniques in the preservation or restoration of SF in women after RC. The review explores the intricacies of preoperative evaluation tools, and intraoperative techniques for organ- and nerve-sparing during radical cystectomy in females. Particular emphasis on vaginal reconstruction after partial or complete resection is provided, including split-thickness skin (STF) graft vaginoplasy, pedicled flaps, myocutaneous flaps and use of bowel segments. In conclusion, this narrative review highlights the importance of understanding anatomic considerations and nerve-sparing strategies in promoting postoperative SF and quality of life. Furthermore, the review describes the advantages and limitations of each organ- and nerve-sparing technique and their impact on sexual function and overall well-being.

Pelvic Organ Preservation in Non-muscle-invasive Bladder Cancer: Less Is More

Radical cystectomy (RC) is a treatment option for high-risk non-muscle-invasive bladder cancer (NMIBC) but is associated with high morbidity and a negative impact on quality of life. Reproductive or pelvic organ-sparing cystectomy (ROSC) techniques have emerged as a potential strategy to mitigate some potential effects of standard RC. Here we discuss current knowledge regarding oncological, functional, and sexual function outcomes associated with ROSC and their applicability in NMIBC. These outcomes can be used to make informed clinical decisions regarding cystectomy technique in appropriately staged and selected patients with NMIBC. PATIENT SUMMARY: We reviewed results for bladder cancer control, urinary function, and sexual function after removal of the bladder with and without techniques to spare reproductive or pelvic organs. We found evidence of better sexual function outcomes with a sparing approach without compromise of cancer control. Further studies are needed to assess urinary function and pelvic floor-related outcomes.

Female sexual function in bladder cancer: A review of the evidence

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.

Radical cystectomy and women's sexual health - can we do better?

PURPOSE OF REVIEW

Female sexual function after radical cystectomy is a crucial, but historically overlooked component of bladder cancer survivorship. This review focuses on recent studies, which have investigated pelvic health and sexual function after radical cystectomy. We discuss modifiable factors, which may contribute to decreased sexual function after radical cystectomy and techniques, which may lead to improved outcomes.

RECENT FINDINGS

Sexual function is important to women and there is a significant desire (and unmet need) for more perioperative counseling and discussion regarding sexual function changes and quality of life impacts. Sexual function may be altered due to a combination of hormonal changes from ovarian removal, anatomic changes from vaginal alteration, and sensation changes due to damage to the neurovascular bundle. Techniques to preserve these structures have been developed.

SUMMARY

Sexual function is an important component of survivorship and increasing attention is being focused on this area. Long term studies with objective measures are needed for to compare various techniques and ensure oncologic safety. Ovarian preservation, anterior vaginal wall preservation, and vaginal estrogen replacement should be carefully considered for most patients.
