Quality of Life in Non-Muscle-Invasive Bladder Cancer Survivors: A Systematic Review

Effect of Prehabilitation Interventions in People Affected by Bladder Cancer on Long-Term Physical, Clinical, and Patient-Reported Outcome Measures: A Systematic Review

PURPOSE

To understand the effect of prehabilitation interventions on ≥30 days post-treatment outcomes including physical functioning, clinical, and patient-reported outcomes in people affected by bladder cancer.

METHODS

This systematic review included all randomized, quasi-randomized, or single-arm studies in patients affected by bladder cancer (irrespective of stage or treatment modality) that compared prehabilitation intervention(s) with standard care. A range of key terms related to bladder cancer and prehabilitation were developed to search the four electronic databases. Articles were assessed according to predetermined inclusion and exclusion criteria. A methodological quality assessment was performed.

RESULTS

Of the 932 studies identified, 14 studies were included and represented 1,034 participants. The interventions included multimodality prehabilitation (n = 5), exercise-only programs (n = 3), nutrition-focused interventions (n = 2), educational support (n = 3), and smoking/alcohol cessation counseling (n = 1). All of the studies were conducted in patients treated by surgery, therefore clinical and research gaps exist in the prehabilitation interventions among patients treated by intravesical therapy (ie, BCG) or radiotherapy. The key findings highlighted that multimodal program mainly showed improvements in physical function outcomes. Exercise-only interventions demonstrated some benefits in physical function. Nutrition-only interventions did not show any statistically significant improvements. Education programs showed improvements in patient-reported outcomes. Smoking and alcohol cessation counseling achieved notable abstinence rates, which were associated with fewer postoperative complications.

CONCLUSION

This review suggests that prehabilitation interventions may benefit patients with bladder cancer, particularly exercise and education programs, which showed improvements in physical function and patient-reported outcomes. However, the evidence remains inconclusive, with no clear impact on clinical outcomes such as complications or hospital stay. More robust studies are needed to determine the most effective prehabilitation strategies for patients with bladder cancer.

Health-related Quality of Life During the First 4 Years After Non-Muscle-invasive Bladder Cancer Diagnosis: Results of a Large Multicentre Prospective Cohort

BACKGROUND

The health-related quality of life (HRQoL) of patients with non-muscle-invasive bladder cancer (NMIBC) may be impaired due to the chronic and burdensome disease course, but longitudinal data are limited.

OBJECTIVE

To evaluate HRQoL outcomes during the first 4 yr after NMIBC diagnosis, and to compare HRQoL across patient characteristics and with a normative population.

DESIGN, SETTING, AND PARTICIPANTS

Patients with NMIBC (n = 1019) were included from the multicentre prospective cohort UroLife. Data were collected at 6 wk (baseline), and 3, 15, and 51 mo after diagnosis. Longitudinal reference data were obtained from an age- and sex-matched normative population (n = 490).

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

Cancer- and NMIBC-specific HRQoL outcomes (range 0-100) were evaluated by the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 and EORTC QLQ-NMIBC24 questionnaires, respectively. Linear mixed modelling was used to analyse within-group changes and between-group differences.

RESULTS AND LIMITATIONS

The majority of HRQoL outcomes remained stable over time. Observed changes were only of small clinical relevance. Improvements were noted in insomnia, social functioning, and three NMIBC-specific symptoms, while minor deteriorations in appetite and diarrhoea lasted until 51 mo. HRQoL in some domains was worse for high-grade NMIBC, high European Association of Urology (EAU) risk group, initial Bacillus Calmette-Guérin (BCG) treatment, being female, and being younger (<65 yr); yet differences were few, small, and temporary. No differences were observed across recurrence status. Compared with a normative population, clinically relevant worse scores were observed for six of 15 outcomes, which mostly recovered at 51 mo, except for minor symptoms of appetite loss and diarrhoea.

CONCLUSIONS

No remarkable changes in HRQoL were observed during the first 4 yr after NMIBC diagnosis. Grade, EAU risk group, initial treatment, recurrence, sex, and age did not importantly affect HRQoL. HRQoL was largely comparable with that of the general population, especially after 4 yr.

PATIENT SUMMARY

Quality of life is not largely affected during the first 4 yr after non-muscle-invasive bladder cancer diagnosis.

Factors influencing health-related quality of life in patients with bladder or kidney cancer: a prospective cohort study of the impact of nutritional status and frailty phenotype

PURPOSE

This study aimed to investigate the impact of nutritional status and frailty phenotype and the predictors of temporal changes on health-related quality of life (HRQoL) of patients with bladder or kidney cancer.

METHODS

Frailty phenotype, Patient-Generated Subjective Global Assessment, and Quality-of-life questionnaire Core-30 were applied twice to patients diagnosed with bladder or kidney cancer. Patients also completed a sociodemographic questionnaire, and clinical data were collected from records.

RESULTS

Sixty-two individuals completed the study, mostly male, with a mean age of 62.5 (± 11.4) years. The median time of follow-up was 14.5 months. Role functioning, emotional functioning, and fatigue improved over time (p < 0.05). The factors that negatively affected the long-term quality of life summary score were being female, malnourished, pre-frail and frail, cancer treatment, performance status, and lower income. Using the multivariate model, being malnourished (β =  - 7.25; 95% CI, - 10.78 to - 3.71; p < 0.001), frail (β =  - 7.25; 95% CI, - 13.39 to - 1.11; p = 0.021), and each one-point increase in performance status (β =  - 6.9; 95% CI, - 9.54 to - 4.26; p < 0.001), were the ones that most negatively impacted the HRQoL between the two assessments.

CONCLUSION

This study confirmed that frailty, nutritional status, and performance status are the main predictors of HRQoL of patients with bladder or kidney cancer over time.

IMPLICATIONS FOR CANCER SURVIVORS

These findings may be the first step towards highlighting the importance of preventing malnutrition and frailty, in favor of a better long-term QoL for cancer patients.

20-hydroxyecdysone suppresses bladder cancer progression via inhibiting USP21: A mechanism associated with deubiquitination and degradation of p65

Bladder cancer is one of the most common malignancies of the urinary tract and a prevalent cancer worldwide, still requiring efficient therapeutic agents and approaches. 20-Hydroxyecdysone (20-HE), a steroid hormone, can be found in insects and few plants and mediate numerous biological events to control the progression of varying diseases; however, its impacts on bladder cancer remain unclear. In the study, we found that 20-HE treatments effectively inhibited the viability and proliferation of bladder cancer cells and induced apoptosis by activating Caspase-3. The migratory and invasive potential of bladder cancer cells was markedly repressed by 20-HE in a dose-dependent manner. The inhibitory effects of 20-HE on bladder cancer were confirmed in an established xenograft mouse model, as indicated by the markedly reduced tumor growth rates and limited lung and lymph node metastasis. High-throughput RNA sequencing was performed to explore dysregulated genes in bladder cancer cells after 20-HE treatment. We identified ubiquitin-specific protease 21 (USP21) as a key deubiquitinating enzyme for bladder cancer progression and a positive correlation between USP21 and nuclear factor-κB (NF-κB)/p65 in patients. Furthermore, 20-HE treatments markedly reduced USP21 expression, NF-κB/p65 mRNA, stability and phosphorylated NF-κB/p65 expression levels in bladder cancer cells, which were validated in animal tumor tissues. Mechanistic studies showed that USP21 directly interacted with and stabilized p65 by deubiquitinating its K48-linked polyubiquitination in bladder cancer cells, which could be abolished by 20-HE treatment, contributing to p65 degradation. Finally, we found that USP21 overexpression could not only facilitate the proliferation, migration, and invasion of bladder cancer cells, but also significantly eliminated the suppressive effects of 20-HE on bladder cancer. Notably, 20-HE could still perform its anti-tumor role in bladder cancer when USP21 was knocked down with decreased NF-κB/p65 expression and activation, revealing that USP21 suppression might not be the only way for 20-HE during bladder cancer treatment. Collectively, all our results clearly demonstrated that 20-HE may function as a promising therapeutic strategy for bladder cancer treatment mainly through reducing USP21/p65 signaling expression.

Identifying the supportive care needs of people affected by non-muscle invasive bladder cancer: An integrative systematic review

PURPOSE

To understand supportive care needs among people with non-muscle invasive bladder cancer (NMIBC).

METHODS

An integrative systematic review was reported using the Preformed Reporting Items for Systematic Review and Meta-analyses (PRISMA) guidelines. Seven electronic databases were searched for relevant studies, including all quantitative, qualitative, and mixed methods studies, irrespective of research design. The review process was managed by Covidence systematic review software. Two reviewer authors independently performed data extraction using eligibility criteria. Quality appraisal was conducted, and a narrative synthesis was performed.

RESULTS

A total of 1129 articles were screened, of which 21 studies met the inclusion criteria. The findings revealed that the frequency of supportive care needs reported by NMIBC participants included psychological/emotional (16/21:76%), physical (16/21:76%), practical (8/21:38%), interpersonal/intimacy (7/21:33%), family-related (7/21:33%), health system/information (5/21:23%), social (4/21:19%), patient-clinician communication (3/21:14%), spiritual (1/21:5%) and daily needs (1/21:5%).

CONCLUSION

People affected by NMIBC experience anxiety, depression, uncertainty, and fear of recurrence. The physical symptoms reported included urinary issues, pain, sleeping disorders and fatigue. These supportive care needs persist throughout the participants' treatment trajectory and can impact their quality of life.

IMPLICATIONS FOR CANCER SURVIVORS

Identifying supportive care needs within the NMIBC population will help inform future interventions to provide patient-centred care to promote optimal well-being and self-efficacy for people diagnosed with NMIBC.

Longitudinal associations of adherence to lifestyle recommendations and health-related quality of life in patients with non-muscle invasive bladder cancer

Although the role of lifestyle in health-related quality of life (HRQoL) outcomes has been increasingly recognized for various types of cancer, evidence in patients with non-muscle invasive bladder cancer (NMIBC) is very limited. We aimed to evaluate the longitudinal association between adherence to the 2018 World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) lifestyle recommendations and HRQoL in patients with NMIBC. This study included 1029 patients with NMIBC recruited between May 2014 and April 2017 from the Dutch multi-centre prospective cohort study UroLife. Lifestyle and HRQoL data were collected at 6 weeks (baseline), 3 months and 15 months after diagnosis. Information on body mass index (BMI), physical activity, diet and alcohol was used to compute the standardized WCRF/AICR adherence score (0-7). HRQoL outcomes were evaluated by the EORTC QLQ-C30. Linear mixed models were used to assess longitudinal confounder-adjusted associations between the WCRF/AICR adherence score and HRQoL outcomes. Adherence to each additional WCRF/AICR recommendation was associated with better global quality of life, physical, role and social functioning, and less fatigue. We found stronger inter-individual than intra-individual associations, suggesting that associations were mainly driven by between-subject differences. Higher adherence to the BMI, physical activity and dietary recommendations was associated with better scores for most HRQoL outcomes, while adherence to the alcohol recommendation (ie, non-consumption) was associated with worse HRQoL. Following the WCRF/AICR lifestyle recommendations may improve HRQoL in patients with NMIBC. Intervention studies are needed to establish whether the association between lifestyle and HRQoL is causal.

The current use of the EORTC QLQ-NMIBC24 and QLQ-BLM30 questionnaires for the assessment of health-related quality of life in bladder cancer patients: a systematic review

PURPOSE

Investigating the use of the EORTC bladder cancer (BC) modules by evaluating: (a) study contexts/designs; (b) languages/countries in which the modules were administered; (c) their acceptance by patients/investigators; and (d) their psychometric properties.

METHODS

A systematic review was performed with studies from 1998 until 20/10/2021 in five databases. Articles/conference abstracts using the EORTC-QLQBLM30 (muscle invasive BC) and the EORTC-QLQNMIBC24 (previously referred to as QLQ-BLS24; non-muscle invasive BC) were included. Two authors independently screened titles/abstracts/full-texts and performed data extraction.

RESULTS

A total of 76 eligible studies were identified. Most studies included the BLM30 (n = 53), were in a urological surgery context (n = 41) and were cross-sectional (n = 35) or prospective (n = 30) in design. The BC modules were administered in 14 languages across 19 countries. Missing data were low-moderate for all non-sex related questions (< 1% to 15%). Sex-related questions had higher rates of missing data (ranging from 6.9% to 84%). Most investigators did not use all scales of the questionnaires. One validation study for the original BLS24 led to the development of the NMIBC24, which adopted a new scale structure for which good structural validity was confirmed (n = 3). Good reliability and validity was shown for the NMIBC24 module, except for malaise and bloating/flatulence scales. Psychometric evidence for BLM30 is lacking.

CONCLUSION

These results provide insight into how the EORTC BC quality of life modules could be further improved. Current work is ongoing to update the modules and to determine if the two modules can be combined into a single questionnaire that works well in both the NMIBC and MIBC settings.

Urdu Translation and Linguistic Validation of the Bladder Cancer Index Questionnaire

Background

This study aimed to translate the Bladder Cancer Index (BCI) questionnaire to Urdu and validate it to assess the quality of life of patients with bladder cancer.

Material and methods

After forward and backward translation of the BCI questionnaire into Urdu, content validity was calculated using the content validity index (CVI) based on input from five health experts regarding the clarity and relevance of the questionnaire. Construct validity was measured by comparing the inter-scale domains and subdomains of BCI and by comparing BCI with Short Form 36 (SF-36) using correlations. For assessment of reliability, Cronbach’s alpha was calculated to measure internal consistency and for test-retest reliability, the questionnaire was re-administered four weeks later and the correlation of responses at baseline and at a four-week time point was evaluated.

Results

The questionnaire has good content validity for clarity (0.91) and relevance (0.87). The construct validity of BCI was also adequately displayed by moderate to high correlation between different subdomains of BCI (Pearson’s r: urinary - 0.62, bowel - 0.78, sexual function - 0.43) and low to moderate correlation between responses of BCI compared with SF-36 (Pearson’s r mostly >0.45). Test-retest reliability was excellent (Pearson’s r 0.90-0.98), and there was good internal consistency (Cronbach’s alpha 0.79-0.92) in the different domains of the questionnaire.

Conclusion

The Urdu-translated BCI is a valid and reliable tool to measure the impact of bladder cancer on the quality of life of patients.

Relationships among uncertainty, post-traumatic stress disorder symptoms, and quality of life in non-muscle-invasive bladder cancer survivors

PURPOSE

The aim of this study was to examine relationships among uncertainty, PTSD symptoms (PTSS), and quality of life (QOL) in non-muscle-invasive bladder cancer (NMIBC) survivors.

METHODS

Eligible NMIBC survivors were identified through the North Carolina Central Cancer Registry, and 398 survivors participated in a mailed survey that measured survivor's outcomes (uncertainty, PTSS, and QOL). Structural equation modeling was used to examine the mediating effect of uncertainty and PTSS on the association between personal characteristics and QOL in NMIBC survivors.

RESULTS

NMIBC survivors experienced cancer-related uncertainty; higher uncertainty was associated with male, lower income, lack of cure, and lower cognition-ability. Uncertainty was significantly and negatively associated with QOL. In addition, PTSS completely mediated the effect of uncertainty on QOL, and higher PTSS had a strong association with poorer QOL. Additionally, comorbidities, cognition-general concerns, uncertainty, and PTSS had strong negative effects on QOL.

CONCLUSION

This study has identified modifiable psychosocial factors which affect QOL in NMIBC survivors. The study findings can be used in the development of interventions to improve QOL for NMIBC survivors.

The Paris System for reporting urinary cytology improves the negative predictive value of high-grade urothelial carcinoma

BACKGROUND

The Paris System (TPS) for reporting urinary cytology differs from conventional systems (CS) in that it focuses on the diagnosis of high-grade urothelial carcinoma (HGUC). This study investigated the impact of TPS implementation on the diagnostic accuracy of HGUC by comparing it with our institutional CS.

METHODS

A total of 649 patients who underwent transurethral resection of bladder tumor (TURBT) between January 2009 and December 2020 were included in this study. Our institution adopted TPS to report urinary cytology in February 2020. The diagnostic accuracy of HGUC in preoperative urinary cytology was compared with the presence or absence of HGUC in resected specimens of TURBT before and after TPS implementation.

RESULTS

After implementing TPS in urinary cytology, 89 patients were reviewed and compared with 560 patients whose urinary cytology was diagnosed by CS. TPS and CS for detecting HGUC had 56.0% and 58.2% sensitivity, 97.8% and 91.2% specificity, and 93.3% and 87.9% positive predictive values, respectively. There were no significant differences between TPS and CS in terms of sensitivity, specificity, and positive predictive value for HGUC (P = 0.83, 0.21, 1.00). On the other hand, the negative predictive value for HGUC using TPS was 80.0%, which was significantly higher than that of CS (66.4%, P = 0.04) The multivariate logistic regression analysis indicated that not using TPS was one of the independent predictive factors associated with false-negative results for HGUC (odds ratio, 2.26; 95% confidence interval, 1.08-4.77; P = 0.03).

CONCLUSION

In instances where urinary cytology is reported as negative for HGUC by TPS, there is a low probability of HGUC, indicating that TPS has a potential diagnostic benefit.

Anxiety, depression and urological cancer outcomes: A systematic review

PURPOSE

The interplay between physical and mental aspects of a cancer diagnosis are well recognised. However, little consensus exists on the impact of depression and anxiety on urological cancer outcomes. Therefore, this systematic review aimed to investigate the relationship between these conditions and functional or oncological outcomes in urological malignancy.

MATERIALS AND METHODS

A systematic search was conducted using PubMed, Embase, PsycINFO and Global Health databases up to June 2020. Studies evaluating the relationship of anxiety and depression disorders or symptoms on functional and mortality outcomes were included. Outcome measures included validated urinary, sexual, body image questionnaire scores and all-cause or disease-specific mortality.

RESULTS

Of 3,966 studies screened, 25 studies with a total of 175,047 urological cancer patients were included. Significant anxiety and depressive symptoms and disorders were found to impact functional outcomes in several cancer types. A consistent negative association existed for sexual function in prostate, testicular and penile cancer patients. Additionally, poorer urinary function scores were seen in prostate cancer, with increased body image issues in testicular and prostate cancer. Importantly, both overall and disease-specific mortality outcomes were poorer in bladder and prostate cancer patients.

CONCLUSIONS

Co-existing depression and anxiety appears to be negatively associated with functional and mortality outcomes in urological cancers. This appears especially evident in male cancers, including prostate and testicular cancer. Although not proving causation, these findings highlight the importance of considering mental wellbeing during follow-up for early recognition and treatment. However, current evidence remains heterogenous, with further studies required exploring patients at risk.

Effect of individualized psychological intervention on negative emotion and sleep quality of patients after bladder cancer surgery: a randomized controlled trial

Background

Bladder surgery has a negative impact on patients' mental health, sleep quality. Conventional nursing interventions failed to meet the clinical needs. Therefore, this parallel-group RCT was performed to assess the effect of individualized psychological intervention on patients' negative emotions and sleep quality after bladder cancer surgery.

Methods

Patients with bladder cancer admitted to our hospital (from September 2018 to October 2020) and underwent surgical treatment were selected as the research objects. They were randomly allocated to a parallel control group or observation group based on a computer-generated random numbers table. Because our study included behavioral intervention, blinding was not possible for participants and care givers. The control group received conventional nursing care, and the observation group received strengthened individualized psychological intervention under the nursing measures of the control group. Sleep quality, anxiety, depression, nursing compliance, and the occurrence of bladder spasm were compared between the two groups.

Results

Seventy-eight eligible patients were included and randomly divided in two groups (n=39 for each group). The intervention procedure was completed without losses and exclusions of patients after randomization. Before the intervention, the Pittsburgh Sleep Quality Index Scale and the anxiety and depression scores were comparable between the two groups (P>0.05). After the intervention, the data of the two groups were significantly improved. The sleep quality, sleep time, sleep efficiency, the time to fall asleep, hypnotic drugs, sleep disorders, daytime dysfunction, anxiety score, and depression score of the observation group were lower than those of the control group, with significant differences (P<0.05). The total nursing compliance rate of the observation group reached 100.00%, which was higher than the control group. The difference between the groups was significant (P<0.05). There was no significant difference in the incidence of bladder spasm between the two groups (P>0.05).

Conclusions

Individualized psychological intervention applied to bladder cancer surgery can effectively improve patients' negative emotions and improve their sleep quality.

Cruciferous Vegetable Intervention to Prevent Cancer Recurrence in Non-Muscle Invasive Bladder Cancer Survivors: Development using a Systematic Process (Preprint)

Background

Bladder cancer is one of the top 10 most common cancers in the United States. Most bladder cancers (70%-80%) are diagnosed at early stages as non–muscle-invasive bladder cancer (NMIBC), which can be removed surgically. However, 50% to 80% of NMIBC cases recur within 5 years, and 15% to 30% progress with poor survival. Current treatments are limited and expensive. A wealth of preclinical and epidemiological evidence suggests that dietary isothiocyanates in cruciferous vegetables (Cruciferae) could be a novel, noninvasive, and cost-effective strategy to control NMIBC recurrence and progression.

Objective

The aim of this study is to develop a scalable dietary intervention that increases isothiocyanate exposure through Cruciferae intake in NMIBC survivors.

Methods

We worked with a community advisory board (N=8) to identify relevant factors, evidence-based behavior change techniques, and behavioral theory constructs used to increase Cruciferae intake in NMIBC survivors; use the PEN-3 Model focused on incorporating cultural factors salient to the group’s shared experiences to review the intervention components (eg, the saliency of behavioral messages); administer the revised intervention to community partners for their feedback; and refine the intervention.

Results

We developed a multicomponent intervention for NMIBC survivors consisting of a magazine, tracking book, live telephone call script, and interactive voice messages. Entitled POW-R Health: Power to Redefine Your Health, the intervention incorporated findings from our adaptation process to ensure saliency to NMIBC survivors.

Conclusions

This is the first evidence-based, theoretically grounded dietary intervention developed to reduce bladder cancer recurrence in NMIBC survivors using a systematic process for community adaptation. This study provides a model for others who aim to develop behavioral, community-relevant interventions for cancer prevention and control with the overall goal of wide-scale implementation and dissemination.

Quality of life in patients undergoing surveillance for non-muscle invasive bladder cancer-a systematic review

Background

The main objective of this study was to evaluate the various instruments available to evaluate the quality of life (QoL) in patients diagnosed with non-muscle invasive bladder cancer (NMIBC) undergoing surveillance.

Methods

A PubMed literature review was carried out with query terms (“Urinary Bladder Neoplasms” [Mesh] OR “Bladder malignancy”) AND (“quality of life”) including all studies up to June 2020. This resulted in 576 peer-reviewed articles. A further 12 articles from additional sources were included. A total of 473 articles were eliminated due to lack of relevance to the topic of concern. A further 93 articles evaluating NMIBC and articles evaluating Radiotherapy were excluded and a total of 22 studies were studied.

Results

In total, 22 studies were identified. The vast majority of studies were prospective descriptive studies (n=9), while there were 7 cross-sectional surveys and 6 randomised controlled trials. Most studies evaluated the impact of intravesical treatment on QoL. NMIBC survivors had significantly lower QoL compared to the general population, Surveillance strategies involving repeated intravesical therapies and cystoscopies have a negative impact on QoL with impaired physical function and mental health.

Conclusions

This article emphasizes the importance of assessing the QoL in patients with NMIBC undergoing long term surveillance, as they represent the majority of bladder cancer patients. Development and validation of specific instruments to measure QoL in patients with NMIBC are desperately needed to assess, better understand, and manage the burden of disease and healthcare in this group of patients.

"Picture this"- Patients' Drawings of Non-Muscle Invasive Bladder Cancer: A Novel Method to Help Understand How Patients Perceive Their Condition

BACKGROUND

There is a paucity of data regarding patient experiences of living with non-muscle-invasive bladder cancer (NMIBC).

OBJECTIVES

To investigate patients' beliefs about NMIBC utilising both a well-established verbal/linguistic method, the Brief Illness Perception Questionnaire (B-IPQ) in addition to a novel visual/perceptual method, that is, asking patients to draw their bladder as it is now and as they perceive it will be in the future.

METHODS

Cross-sectional study of patients with NMIBC. Patients completed: (i) the B-IPQ, and (ii) 2 drawings of their bladder: as they perceived it currently and as they perceived it would look in 5 years' time.

RESULTS

A total of 118 patients completed the B-IPQ, of which 96 produced 2 bladder drawings. Forty-seven per cent of patients depicted no change in their bladder across time, 35% depicted improvements, while 18% drew their NMIBC as deteriorating between the two time points. Patients who drew their NMIBC worsening over time reported significantly stronger beliefs in the severity of current consequences from their NMIBC (F(2,94) = 9.07, p < 0.001, m = 5.68, 95% CI 4.38-6.88) and greater current concerns about their NMIBC (F(2,94) = 6.17, p < 0.01, m = 7.06, 95% CI 5.47-8.66). This was unrelated to cancer grade, cancer stage, treatment or demographic variables.

CONCLUSION

This is the first study to explore beliefs about NMIBC in a sample of patients with NMIBC attending routine clinics using both a well-established and a novel method of assessing patients' perceptions. Results highlight the usefulness of a simple non-verbal technique, in identifying patients' concerns about the condition. Almost one fifth of patients with NMIBC may experience significant concerns about the worsening of their condition, which appear to be independent of demographic, histopathological, and treatment related variables. Further exploration of the psychological concerns of individuals with NMIBC is required in order to appropriately plan for needs led multidisciplinary approach in their care.

Improving hexaminolevulinate enabled cancer cell detection in liquid biopsy immunosensors

Hexaminolevulinate (HAL) induced Protoporphyrin IX (PpIX) fluorescence is commonly used to differentiate cancer cells from normal cells in vivo, as for instance in blue light cystoscopy for bladder cancer diagnosis. A detailed approach is here provided to use this diagnostic principle ex vivo in an immunosensor device, towards enabling non-invasive cancer diagnostic from body fluids, such as urine. Several factors susceptible to affect the applicability of HAL-assisted diagnosis in body fluids were tested. These included the cell viability and its impact on PpIX fluorescence, the storage condition and shelf life of HAL premix reagent, light exposure (360–450 nm wavelengths) and its corresponding effect on both intensity and bleaching of the PpIX fluorescence as a function of the microscopy imaging conditions. There was no significant decrease in the viability of bladder cancer cells after 6 h at 4 °C (student’s t-test: p > 0.05). The cellular PpIX fluorescence decreased in a time-dependent manner when cancer cells were kept at 4 °C for extended period of time, though this didn’t significantly reduce the fluorescence intensity contrast between cancer and non-cancer cells kept in the same condition for 6 h. HAL premix reagent kept in long term storage at 4 °C induced stronger PpIX fluorescence than reagent kept in the − 20 °C freezer. The PpIX fluorescence was negatively affected by repeated light exposure but increased with illumination intensity and exposure time. Though this applied to both healthy and cancer cell lines, and therefore did not statistically improved the differentiation between cell types. This study revealed important experimental settings that need to be carefully considered to benefit from the analytical potential of HAL induced fluorescence when used in technologies for the diagnosis of cancer from body fluids.

Well-being and Perceptions of Supportive Resources among Caregivers of Patients with Bladder Cancer

BACKGROUND

The unique burden of treatment and survivorship of patients with bladder cancer can negatively impact caregiver experience and their use of supportive care resources.

OBJECTIVE

To assess caregivers' well-being and their perception of potential supportive resources.

METHODS

In this cross-sectional survey, caregivers of patients with bladder cancer (N = 630) were recruited through the nationwide Bladder Cancer Advocacy Network Patient Survey Network. We used stakeholder-developed questionnaires to examine caregiver well-being (i.e., physical well-being, tiredness, fear, worry, sadness), the perceived helpfulness of potential resources (i.e., web-based and print-based information, specialized support, personal stories of other caregivers, phone-call and online chat with other caregivers), and influencing factors.

RESULTS

Caregivers more frequently reported emotional well-being as a moderate to serious problem (67% for fear, 78% for worry, 66% for sadness) compared with physical well-being (30%) and tiredness (47%). Decreased well-being was associated with female gender of the caregiver, higher than high school education, or caring for a patient with advanced (versus non-invasive) bladder cancer. Of six potential resources, "web-based information" was perceived as "very helpful" among 79% of respondents, followed by "personal stories from other caregivers" (62%). Caregiver preferences for "web-based information" was not associated with any specific demographic or clinical factors.

CONCLUSIONS

Caregivers reported moderate to serious problems with emotional and physical well-being. Web-based platforms were perceived as beneficial supportive resources for bladder cancer caregivers. Future intervention research should target the influencing factors identified in this study to optimize the health outcomes of caregivers and enhance the supportive care resources for improving their well-being.

Supportive Care Needs of Patients on Surveillance and Treatment for Non-Muscle-Invasive Bladder Cancer

OBJECTIVE

This literature review provides an overview of non-muscle-invasive bladder cancer diagnosis (NMIBC), treatment, and surveillance. Existing evidence is reviewed to identify the NMIBC patient pathway, highlight its effect on quality of life, and identify supportive care needs of this patient group. A framework to guide nurses in the care of this underserved population is proposed.

DATA SOURCES

Electronic databases including CINAHL, Medline, PsychInfo, Cochrane, and Google Scholar were searched.

CONCLUSION

NMIBC is a chronic disease with high recurrence and progression rates with most patients requiring invasive treatment and burdensome surveillance schedules with frequent hospital visits. Treatment-related side effects may interrupt therapy and possibly result in its discontinuation. Patients' quality of life can be negatively affected at various stages of the cancer trajectory. Specialist nurses provide holistic care throughout all stages of the patient journey to optimize supportive care, information provision, and delivery of appropriate treatment and surveillance protocols. NMIBC research is historically underfunded with a paucity of evidence identifying the supportive care needs of this population. Further research is urgently required to fill the gaps identified.

IMPLICATIONS FOR NURSING PRACTICE

This timely paper raises the profile of unmet supportive care needs in an underserved research cancer population. Suggestions are proposed to improve the quality of nursing care through standardized practices and the development and integration of patient pathways. Evidence of the effect of NMIBC on family members or carers is absent from the literature. Future research implications and directions are proposed.

Cancer cell detection device for the diagnosis of bladder cancer from urine

Bladder cancer is common and has one of the highest recurrence rates. Cystoscopy, the current gold standard diagnosis approach, has recently benefited from the introduction of blue light assisted photodynamic diagnostic (PDD). While blue light cystoscopy improves diagnostic sensitivity, it remains a costly and invasive approach. Here, we present a microfluidic-based platform for non-invasive diagnosis which combines the principle of PDD with whole cell immunocapture technology to detect bladder cancer cells shed in patient urine ex vivo. Initially, we demonstrate with model cell lines that our non-invasive approach achieves highly specific capture rates of bladder cancer cells based on their Epithelial Cell Adhesion Molecule expression (>90%) and detection by the intensity levels of Hexaminolevulinic Acid-induced Protoporphyrin IX fluorescence. Then, we show in a pilot study that the biosensor platform successfully discriminates histopathologically diagnosed cancer patients (n = 10) from non-cancer controls (n = 25). Our platform can support the development of a novel non-invasive diagnostic device for post treatment surveillance in patients with bladder cancer and cancer detection in patients with suspected bladder cancer.

KEYNOTE-676: Phase III study of BCG and pembrolizumab for persistent/recurrent high-risk NMIBC

Background: Nonmuscle-invasive bladder cancer (NMIBC) is the most common form of bladder cancer, with high rates of disease recurrence and progression. Current treatment for high-risk NMIBC involves Bacillus Calmette-Guérin (BCG) therapy, but treatment options are limited for patients with recurrent or BCG-unresponsive disease. Aberrant programmed death 1 signaling has been implicated in BCG resistance and bladder cancer recurrence and progression, and pembrolizumab has shown efficacy in patients with BCG-unresponsive high-risk NMIBC. Aim: To describe the rationale and design for the randomized, comparator-controlled Phase III KEYNOTE-676 study, which will evaluate the efficacy and safety of pembrolizumab in combination with BCG in patients with persistent/recurrent high-risk NMIBC after BCG induction therapy. Trial registration number: NCT03711032.

Exploring patients' experience and perception of being diagnosed with bladder cancer: a mixed-methods approach

Objective

To determine patient experience and perception following a diagnosis of non‐muscle‐invasive bladder cancer (NMIBC).

Patient and methods

Patients were part of a prospective multicentre observational study recruiting patients with NMIBC for a urine biomarker study (DETECT II; ClinicalTrials.gov: NCT02781428). A mixed‐methods approach comprising: (i) the Brief Illness Perception Questionnaire (Brief‐IPQ) and (ii) semi‐structured interviews to explore patients’ experience of having haematuria, and initial and subsequent experience with a NMIBC diagnosis. Both assessments were completed at 6 months after NMIBC diagnosis.

Results

A total of 213 patients completed the Brief‐IPQ. Patients felt that they had minimal symptoms (median [interquartile range, IQR] score 2 [0–5]) and were not particularly affected emotionally (median [IQR] score 3 [1–6]) with a minimal effect to their daily life (median [IQR] score 2 [0–5]). However, they remained concerned about their cancer diagnosis (median [IQR] score 5 [3–8]) and felt that they had no personal control over the cancer (median [IQR] score 2 [2–5]) and believed that their illness would affect them for some time (median [IQR] score 6 [3–10]). A significant association with a lower personal control of the disease (P < 0.05) and a poorer understanding of the management of NMIBC (P < 0.05) was seen in patients aged >70 years. Many patients were uncertain about the cause of bladder cancer. Qualitative analysis found that at initial presentation of haematuria, most patients were not aware of the risk of bladder cancer. Patients were most anxious and psychologically affected between the interval of cystoscopy diagnosis and transurethral resection of bladder tumour (TURBT). Following TURBT, most patients were positive about their cancer prognosis.

Conclusion

Patients with NMIBC have a poor perception of disease control and believe that their disease will continue over a prolonged period of time. This is particularly more pertinent in the elderly. Patients are most psychologically affected during the interval between cancer diagnosis following cystoscopy and TURBT. Health awareness about bladder cancer remained poor with a significant number of patients unaware of the causes of bladder cancer. Psychological support and prompt TURBT following bladder cancer diagnosis would help improve the mental health of patients with NMIBC.

The UroLife study: protocol for a Dutch prospective cohort on lifestyle habits in relation to non-muscle-invasive bladder cancer prognosis and health-related quality of life

INTRODUCTION

Patients with non-muscle-invasive bladder cancer (NMIBC) have a good survival but are at high risk for tumour recurrence and disease progression. It is important to identify lifestyle habits that may reduce the risk of recurrence and progression and improve health-related quality of life (HRQOL). This paper describes the rationale and design of the UroLife study. The main aim of this study is to evaluate whether lifestyle habits are related to prognosis and HRQOL in patients with NMIBC.

METHODS AND ANALYSIS

The UroLife study is a multicentre prospective cohort study among more than 1100 newly diagnosed patients with NMIBC recruited from 22 hospitals in the Netherlands. At 6 weeks and 3, 15 and 51 months after diagnosis, participants fill out a general questionnaire, and questionnaires about their lifestyle habits and HRQOL. At 3, 15 and 51 months after diagnosis, information about fluid intake and micturition is collected with a 4-day diary. At 3 and 15 months after diagnosis, patients donate blood samples for DNA extraction and (dietary) biomarker analysis. Tumour samples are collected from all patients with T1 disease to assess molecular subtypes. Information about disease characteristics and therapy for the primary tumour and subsequent recurrences is collected from the medical records by the Netherlands Cancer Registry. Statistical analyses will be adjusted for age, gender, tumour characteristics and other known confounders.

ETHICS AND DISSEMINATION

The study protocol has been approved by the Committee for Human Research region Arnhem-Nijmegen (CMO 2013-494). Patients who agree to participate in the study provide written informed consent. The findings from our study will be disseminated through peer-reviewed scientific journals and presentations at (inter)national scientific meetings. Patients will be informed about the progress and results of this study through biannual newsletters and through the website of the study and of the bladder cancer patient association.

Health-related quality of life among non-muscle-invasive bladder cancer survivors: a population-based study

OBJECTIVE

To examine the effect of non-muscle-invasive bladder cancer (NMIBC) diagnosis and treatment on survivors' quality of life (QoL).

PATIENTS AND METHODS

Of the 5979 patients with NMIBC diagnosed between 2010 and 2014 in North Carolina, 2000 patients were randomly selected to be invited to enroll in this cross-sectional study. Data were collected by postal mail survey. The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core (QLQ-C30) and the NMIBC-specific module were included in the survey to measure QoL. Descriptive statistics, t-tests, anova, and Pearson's correlation were used to describe demographics and to assess how QoL varied by sex, cancer stage, time since diagnosis, and treatment.

RESULTS

A total of 398 survivors returned questionnaires (response rate: 23.6%). The mean QoL score for QLQ-C30 (range 0-100, higher = better QoL in all domains but symptoms) for global health status was 73.6, function domain scores ranged from 83.9 to 86.5, and scores for the top five symptoms (insomnia, fatigue, dyspnoea, pain, and financial difficulties) ranged from 14.1 to 24.3. The lowest NMIBC-specific QoL domain was sexual issues including sexual function, enjoyment, problems, and intimacy. Women had worse bowel problems, sexual function, and sexual enjoyment than men but better sexual intimacy and fewer concerns about contaminating their partner. Stage Ta had the highest global health status, followed by T1 and Tis. QoL did not vary by time since diagnosis except for sexual function. The cystectomy group (n = 21) had worse QoL in sexual function, discomfort with sexual intimacy, sexual enjoyment, and male sexual problems than the non-cystectomy group (n = 336).

CONCLUSION

Survivors of NMIBC face a unique burden associated with their diagnosis and the often-lifelong surveillance and treatment regimens. The finding has important implications for the design of tailored supportive care interventions to improve QoL for NMIBC survivors.

Prognostic Value of the Neutrophil-to-Lymphocyte Ratio in Nonmuscle-Invasive Bladder Cancer Treated with GreenLight Laser Vaporization

Objective: An elevated neutrophil-to-lymphocyte ratio (NLR) is significantly associated with poor outcomes in many types of malignancies, including bladder cancer. However, the prognostic value of NLR in patients with nonmuscle-invasive bladder cancer (NMIBC) treated with GreenLight photoselective vaporization of bladder tumor (PVBT) has not been well studied. In this study, we aimed to explore the association between NLR and survival outcomes in patients with NMIBC who underwent PVBT. Materials and methods: We retrospectively investigated 463 patients with NMIBC who underwent PVBT in Tianjin Union Medical center from January 2012 to January 2017. The patients were divided into two groups based on the NLR value (NLR ≥2.5 and NLR <2.5). Overall survival (OS), cancer-specific survival (CSS), and recurrence-free survival (RFS) were determined using Kaplan-Meier analysis and the log-rank test. Results: Among 463 patients, age, tumor size, tumor focality, tumor grade, or tumor stage in the two groups did not differ significantly. The median follow-up was 40 months (range, 15-60). Thirty-eight patients (8.2%) died of any cause; 24 (5.2%) patients died of bladder cancer. In addition, 88 (19.0%) patients experienced disease recurrence. Elevated NLR was significantly associated with poor OS (χ² = 7.457, p = 0.002), CSS (χ² = 6.242, p = 0.012), and RFS (χ² = 5.372, p = 0.020) in patients with NMIBC who underwent PVBT. Conclusions: Elevated preoperative NLR was significantly associated with poor OS, CSS, and RFS, and it could be considered as an effective and convenient prognostic biomarker for patients with NMIBC who were treated with PVBT.
