Quality of life in bladder cancer patients receiving medical oncological treatment; a systematic review of the literature

Cost-Utility Analysis of Dose-Dense Methotrexate, Vinblastine, Doxorubicin, and Cisplatin Chemotherapy Regimen in Comparison With Gemcitabine and Cisplatin Chemotherapy Regimen in the Treatment of Patients With Muscle Invasive Bladder Cancer in Iran

OBJECTIVES

Bladder cancer incurs the highest lifetime treatment cost per patient among various cancers. Current guidelines endorse several cisplatin-based regimens as neoadjuvant chemotherapy. This cost-utility analysis aimed to compare 2 primary neoadjuvant chemotherapy regimens-dose-dense methotrexate, vinblastine, doxorubicin, and cisplatin (dd-MVAC) and gemcitabine and cisplatin (GC)-for patients with muscle-invasive bladder cancer, providing economic evidence to inform treatment guidelines in Iran.

METHODS

A Markov decision model was constructed, incorporating 4 states: after radical cystectomy without recurrence, no radical cystectomy, recurrence, and death over a lifetime horizon. Clinical outcomes were derived from the VESPER (French Genito-Urinary Tumor Group and French Association of Urology V05) phase 3 randomized controlled trial, whereas costs were obtained from local Iranian data. The main result involved determining an incremental cost-effectiveness ratio within the simulated population, with a willingness-to-pay threshold of 1656 USD (equivalent to Iran's gross domestic product per capita in 2023). Costs and benefits were discounted at 5.8% per annum, and probabilistic and univariate deterministic sensitivity analyses were conducted.

RESULTS

From the perspective of the Iranian healthcare payer, 6 cycles of dd-MVAC yielded 0.02 greater quality-adjusted life-years compared with 4 cycles of GC, resulting in a cost saving of 1 173 491 USD and an incremental cost-effectiveness ratio of -78 708 870. Consequently, dd-MVAC emerged as the dominant option over a lifetime horizon (23 years). The model proved most sensitive to variations in recurrence and toxicity probabilities during treatment.

CONCLUSIONS

Based on this study's results, dd-MVAC represents a cost-saving treatment regimen per patient in the Iranian health system compared with GC, with superior utility.

Fatigue and related variables in bladder cancer treatment - Longitudinal pilot study

Fatigue is a significant problem in patients with bladder cancer treated by radical cystectomy. This pilot study evaluated fatigue and related variables during a treatment period. Four measurements were made, the first 1 month after the cystectomy, and the next three at an interval of about 3 months each (at 4 months, 7 months, and 10 months after the surgery). In addition to the author's questionnaire (sociodemographic variables and a question about the impact of the disease on the patient's life), the FACIT-F Fatigue (to measure fatigue), NCCN/FACT FBISI-18, version 2 (symptoms, general condition of the patient), HADS (depression, anxiety, and irritability) measures were used. In this study, 21 patients participated in all four measurement periods. The fatigue intensity increased significantly between the first and second measurements and gradually decreased between the third and fourth measurements. As the severity of fatigue increases, can be observed an increase in the sense of the impact of the disease on the patient's life in all except the first measurement. The study revealed statistically significant correlations between fatigue and experiencing symptoms of cancer and treatment at each stage of the study, with the strongest correlations in the second and fourth measurements regarding symptoms of cancer and a stronger correlation in the second compared to the first measurement regarding side effects. At each stage of measurement, the experience of dizziness, lack of appetite, feeling of being sick, and feeling of annoyance from treatment side effects were statistically significantly correlated with fatigue. The intensity of fatigue correlated with the feeling of experiencing difficulties in meeting the needs of the family due to the physical condition in the first measurement (Rho = 0.76), a sense of weakness (Rho = 0.92) and sleepiness (Rho = 0.72) in the second measurement, pain in the third (Rho = 0.77). The greatest number of correlates of fatigue were described in the fourth measurement (all symptoms of cancer and side effects except losing weight). Stress, anxiety, depression and irritability were correlated with fatigue at each of the stages of research except the first one (without differences between the correlation coefficients in the second, third and fourth measurements). Significantly lower levels of fatigue characterised patients who survived over 6 months after the end of the study compared to the first three measurements.

Significance of PD-L1 in Metastatic Urothelial Carcinoma Treated With Immune Checkpoint Inhibitors: A Systematic Review and Meta-Analysis

IMPORTANCE

Immune checkpoint inhibitors (ICIs) have broadened the metastatic urothelial carcinoma (mUC) therapeutic scenario. The association of programmed death ligand 1 (PD-L1) with response and survival in patients treated with ICIs is still controversial.

OBJECTIVES

To evaluate the association of PD-L1 with response rate and overall survival among patients with mUC treated with ICIs.

DATA SOURCES

PubMed, Embase, American Society of Clinical Oncology and European Society for Medical Oncology Meeting Libraries, and Web of Science were searched up to December 10, 2023.

STUDY SELECTION

Two authors independently screened the studies. Included studies were randomized and nonrandomized clinical trials enrolling patients with mUC receiving ICIs with available overall survival (OS), progression-free survival (PFS), or overall response rate (ORR) data, separated between patients with PD-L1-positive and -negative tumors.

DATA EXTRACTION AND SYNTHESIS

The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline was followed. Two reviewers independently extracted data. Fixed- or random-effects models were used depending on the heterogeneity among the studies.

MAIN OUTCOMES AND MEASURES

Primary outcomes were odds ratios (ORs) for ORR and hazard ratios (HRs) for OS, comparing patients with PD-L1-positive tumors and patients with PD-L1-negative tumors. Secondary outcomes were the PFS HR between patients with PD-L1-positive and -negative tumors and OS HR between ICI arms and non-ICI arms of only randomized clinical trials.

RESULTS

A total of 14 studies were selected, comprising 5271 patients treated with ICIs (2625 patients had PD-L1-positive tumors). The ORR was 13.8% to 78.6% in patients with PD-L1-positive tumors and 5.1% to 63.2% in patients with PD-L1-negative tumors, with an association between PD-L1 status and ORR favoring patients with PD-L1-positive tumors (OR, 1.94; 95% CI, 1.47-2.56; P < .001). Median OS ranged from 8.4 to 24.1 months in patients with PD-L1-positive tumors and from 6.0 to 19.1 months in patients with PD-L1-negative tumors. The pooled HR showed a significant reduction for patients with PD-L1-positive tumors compared with those with PD-L1-negative tumors in the risk of death (HR, 0.71; 95% CI, 0.57-0.89; P = .003) and risk of progression (HR, 0.55; 95% CI, 0.44-0.69; P < .001) when ICIs were administered. PD-L1 is not likely to be a predictive biomarker of ICI response.

CONCLUSIONS AND RELEVANCE

This systematic review and meta-analysis suggests that PD-L1 expression is associated with improved ORR, OS, and PFS for patients with mUC who receive ICIs, but it is unlikely to be useful as a predictive biomarker. Developing predictive biomarkers is essential to select patients most likely to benefit from ICIs and avoid toxic effects and financial burden with these agents.

In vivo exposure of the bladder using a non-invasive high intensity focused ultrasound toroidal transducer

A toroidal high-intensity focused ultrasound (HIFU) transducer was used to expose normal bladder wall tissues non-invasively in vivo in a porcine model in order to investigate the potential to treat bladder tumors. The transducer was divided into 32 concentric rings with equal surface areas, operating at 2.5 MHz. Eight animals were split into two groups of 4. In the first group, post-mortem evaluation was performed immediately after ultrasound exposure. In the second group, animals survived for up to seven days before post-mortem evaluation. The ultrasound imaging guided HIFU device was hand-held during the procedure using optical tracking to ensure correct targeting. One thermal lesion in each animal was created using a 40 s exposure at 80 acoustic Watts (free-field) in the trigone region of the bladder wall. The average (±Standard Deviation) abdominal wall and bladder wall thicknesses were 10.3 ± 1.4 mm and 1.1 ± 0.4 mm respectively. The longest and shortest axes of the HIFU ablations were 7.7 ± 2.9 mm and 6.0 ± 1.8 mm, respectively, resulting in an ablation of the whole thickness of the bladder wall in most cases. Ablation were performed at an average depth (distance from the skin surface to the centre of the HIFU lesion) of 42.5 ± 3.8 mm and extended throughout the thickness of the bladder. There were two cases of injury to tissues immediately adjacent to the bladder wall but without signs of perforation, as confirmed by histological analysis. Non-invasive HIFU ablation using a hand-held toroidal transducer was successfully performed to destroy regions of the bladder wall in vivo.

Quality of Life with Monoclonal Antibody Therapies for Locally Advanced or Metastatic Urothelial Carcinoma: A Systematic Review

CONTEXT

Monoclonal antibody (mAb) therapies have improved the prognosis for locally advanced or metastatic urothelial cancers (la/mUC) but little is known about health-related quality of life (HRQoL) with this mode of treatment.

OBJECTIVE

To conduct a systematic review of changes in HRQoL global health and domain scores in patients with la/mUC receiving mAb therapies.

EVIDENCE ACQUISITION

MEDLINE and the American Society of Clinical Oncology and European Society for Medical Oncology meeting databases were searched from January 2015 to June 18, 2022 in accordance with the Preferred Reported Items for Systematic Reviews and Meta-Analyses guidelines. Data were updated on February 3, 2023. Eligible studies were prospective trials assessing HRQoL in patients with la/mUC treated with mAbs. Patients treated for local disease or with radiotherapy or chemotherapy alone were excluded. Meta-analyses, reviews, and case reports were excluded. The validity of randomized trials was assessed using the Risk-of-Bias-2 (RoB2) tool and the strength of outcome evidence was rated using the Grading of Recommendations Assessment, Development and Evaluation approach. The data were analyzed via qualitative synthesis of the evidence.

EVIDENCE SYNTHESIS

Of the 1066 studies identified, nine were included (2364 patients); eight were interventional trials and one was an observational study. The mean change in global health score ranged from -2.8 to 1.9. Constipation, fatigue and pain symptoms, and emotional, physical, role and social functioning improved with treatment in at least two studies. No study demonstrated a significant improvement in global health score. Eight studies reported stability. In the RANGE trial, the global health score decreased. Only two studies had high internal validity according to RoB2 assessment. The HRQoL domain certainty was low, with moderate certainty only for the pain symptom domain. Disease- and treatment-related symptoms, tumor shrinkage, and disease recurrence were correlated to HRQoL.

CONCLUSIONS

Patient HRQoL with mAb therapies for la/mUC did not worsen over time. HRQoL is influenced by several factors related to treatment, tumor characteristics, and the patient's health condition. Evidence was moderate at best and further studies are needed.

PATIENT SUMMARY

We reviewed the evidence on health-related quality-of-life for patients with advanced bladder cancer treated with antibody therapies. We found that quality of life does not worsen on treatment, and sometimes improves. We conclude that these treatments do not negatively affect quality of life, but further studies are needed to draw solid conclusions.

The role of switch maintenance therapy in urothelial cancers

Maintenance therapy with immune checkpoint inhibitors (ICIs) has changed the treatment paradigm of metastatic urothelial carcinoma (mUC). The JAVELIN Bladder 100 trial established avelumab, one of several ICIs in use today, as a life-prolonging maintenance therapy for patients with advanced urothelial carcinoma. Platinum-based chemotherapy is most often used in the first-line treatment of mUC, and while response rates approach about 50%, disease control is usually short-lived upon completion of the standard three to six cycles of chemotherapy. Much progress has been made in recent years in the second-line space and beyond with the use of ICIs, antibody-drug conjugates (ADCs), and tyrosine kinase inhibitors (TKIs) in eligible patients at the time of disease progression post-platinum-based chemotherapy. However, many patients with progressive mUC after first-line chemotherapy suffer from rapid progression of disease, treatment toxicity with subsequent lines of therapy, and a limited life expectancy. Until the results of the JAVELIN Bladder 100 trial were presented in 2020, there were no maintenance strategies proven to be beneficial over best supportive care after disease control is achieved with first-line platinum-based chemotherapy. To date, standard of care frontline treatment of metastatic urothelial cancer remains to be four to six cycles of platinum-based chemotherapy followed by maintenance avelumab. This review summarizes the current evidence available on maintenance therapies in mUC, as well as several highly anticipated clinical trials that we hope will result in further progress in the management of this aggressive cancer and improve patient outcomes.

Impact of Effective Intravesical Therapies on Quality of Life in Patients with Non-Muscle Invasive Bladder Cancer: A Systematic Review

BACKGROUND

Conventional and newly emerged intravesical modalities have demonstrated prophylactic effectiveness that may improve quality of life (QoL) in non-muscle invasive bladder cancer. The purpose of this study is to analyze existing QoL evidence in patients receiving any form of intravesical therapy.

METHODS

A PubMed search without time restriction was conducted to identify all relevant studies in accordance with the PICOT question. Additionally, a search was also performed in the Cochrane library database, Internet, and citation. The CONSORT 2010 checklist and STROBE statement checklist were used to evaluate the risk of bias of the included studies.

RESULTS

A total of 24 eligible articles were included, which consisted of 11 interventional and 13 observational studies. Intravesical therapy with Bacillus Calmette-Guérin (BCG) or certain chemotherapeutic agents worsens symptom burdens and functional performance during the initial induction phase while continuous improved is observed throughout the maintenance treatment and beyond. Hyperthermia has shown a positive trend in enhancing QoL of patients receiving intravesical chemotherapy, which requires more investigations. However, QoL data were unavailable for other forms of immunotherapy, immune checkpoint inhibitors, electromotive drug administration, and photodynamic therapy.

CONCLUSIONS

Limited studies suggested the long-term positive impact of intravesical BCG immunotherapy and chemotherapy. However, existing evidence was lacking to clarify the impact of many emerging intravesical therapies that have suggested to be effective and safe, which demands treatment-specific QoL studies.

Impact of salvage cytotoxic chemotherapy on prognosis in patients with recurrence after radical cystectomy: a multi-institutional retrospective study

Background

In patients experiencing disease recurrence after radical cystectomy (RC) for bladder cancer, data about the impact of clinicopathologic factors, including salvage treatment using cytotoxic chemotherapy, on the survival are scarce. We investigated the prognostic value of clinicopathologic factors and the treatment effect of salvage cytotoxic chemotherapy (SC) in such patients.

Methods

In this retrospective study, we evaluated the clinical data for 86 patients who experienced recurrence after RC. Administration of SC or of best supportive care (BSC) was determined in consultation with the urologist in charge and in accordance with each patient’s performance status, wishes for treatment, and renal function. Statistical analyses explored for prognostic factors and evaluated the treatment effect of SC compared with BSC in terms of cancer-specific survival (CSS).

Results

Multivariate analyses showed that liver metastasis after RC (hazard ratio [HR] 2.13; 95% confidence interval [CI] 1.17 to 3.85; P = 0.01) and locally advanced disease at RC (HR 1.92; 95% CI 1.06 to 3.46; P = 0.03) are independent risk factors for worse CSS in patients experiencing recurrence after RC. In a risk stratification model, patients were assigned to one of two groups based on liver metastasis and locally advanced stage. In the high-risk group, which included 68 patients with 1–2 risk factors, CSS was significantly better for patients receiving SC than for those receiving BSC (median survival duration: 9.4 months vs. 2.4 months, P = 0.005). The therapeutic effect of SC was not related to a history of adjuvant chemotherapy.

Conclusions

The present study indicated the potential value of 1st-line SC in patients experiencing recurrence after RC even with advanced features, such as liver metastasis after RC and locally advanced disease at RC.

Clinical evidence and insights supporting the use of avelumab first-line maintenance treatment in patients with advanced urothelial carcinoma in the Asia-Pacific region

Until recently, international and Asia-specific guidelines for advanced urothelial carcinoma (UC) recommended first-line (1L) platinum-based chemotherapy, followed by second-line (2L) anti-PD-1 or anti-PD-L1 immune checkpoint inhibitor (ICI) therapy where possible, or 1L ICI therapy in cisplatin-ineligible patients with PD-L1+ tumors. However, long-term outcomes remain poor and only a minority of patients receive 2L therapy. The JAVELIN Bladder 100 trial-which assessed avelumab (anti-PD-L1 antibody) as 1L maintenance therapy plus best supportive care (BSC) versus BSC alone in patients with advanced UC that had not progressed with 1L platinum-based chemotherapy-is the only phase 3 trial of ICI-based treatment in the 1L setting to show significantly improved overall survival, and this treatment approach is now recommended in updated treatment guidelines. Available data from the trial suggest that efficacy and safety in patients enrolled in the Asia-Pacific region were similar to findings in the overall population. In this review, we discuss the treatment of advanced UC, with a specific focus on studies in the Asia-Pacific region, and summarize key findings supporting the use of avelumab 1L maintenance as a standard of care in this setting both in cisplatin-eligible and cisplatin-ineligible patients and irrespective of PD-L1 status.

Health-related Quality of Life with Adjuvant Nivolumab After Radical Resection for High-risk Muscle-invasive Urothelial Carcinoma: Results from the Phase 3 CheckMate 274 Trial

BACKGROUND

The programmed death-1 (PD-1) inhibitor nivolumab prolongs disease-free survival in patients with muscle-invasive urothelial carcinoma (MIUC).

OBJECTIVE

To evaluate the effects of nivolumab on health-related quality of life (HRQoL) after radical resection in patients with MIUC.

DESIGN, SETTING, AND PARTICIPANTS

We used data from 709 patients in CheckMate 274 (NCT02632409; 282 with programmed death ligand 1 [PD-L1] expression ≥1%), an ongoing randomized, double-blind, placebo-controlled phase 3 trial of adjuvant nivolumab.

INTERVENTION

Intravenous injection of nivolumab (240 mg) or placebo every 2 wk for ≤1 yr.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

HRQoL was assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and the EQ-5D-3L. Linear mixed-effect models for repeated measures were used to compare nivolumab and placebo on changes in HRQoL. Time to confirmed deterioration (TTCD) of HRQoL was analyzed by Cox proportional hazards regression.

RESULTS AND LIMITATIONS

In the full HRQoL evaluable population, no clinically meaningful deterioration of HRQoL was observed in either treatment arm. Moreover, nivolumab was noninferior to placebo on changes from baseline for all main outcomes. The median TTCD for fatigue was 41.0 wk for nivolumab and 44.3 wk for placebo (hazard ratio [HR]: 1.11, 95% confidence interval [CI], 0.89-1.39). For the visual analog scale, the median TTCD was not reached for nivolumab and it was 57.6 wk for placebo (HR: 0.78, 95% CI, 0.61-1.00). The median TTCD for the other main outcomes was not reached in either treatment arm. The findings were similar for patients with PD-L1 expression ≥1%.

CONCLUSIONS

These results demonstrate that nivolumab did not compromise the HRQoL of patients with MIUC in CheckMate 274.

PATIENT SUMMARY

Nivolumab is being researched as a new treatment for patients with bladder cancer (urothelial carcinoma). We found that nivolumab maintained quality of life while increasing the time until cancer returns in patients whose bladder cancer had spread or grown and who had unsuccessfully tried platinum-containing chemotherapy.

Immune-Checkpoint Inhibitors in Advanced Bladder Cancer: Seize the Day

Background: In advanced bladder cancer (BCa), platinum-based chemotherapy represents the first-choice treatment. In the last ten years, immune checkpoint inhibitors (ICIs) have changed the therapeutic landscape of many solid tumors. Our review aims to summarize the main findings regarding the clinical use of ICIs in advanced BCa. Methods: We searched PubMed, Embase, and Cochrane databases, and conference abstracts from international congresses (ASCO, ESMO, ASCO GU) for clinical trials, focusing on ICIs as monotherapy and combinations in metastatic BCa. Results: 18 studies were identified. ICIs targeting PD1 (nivolumab, pembrolizumab), PD-L1 (avelumab, atezolizumab, durvalumab), and CTLA4 (ipilimumab, tremelimumab) were used. Survival outcomes have been improved by second-line ICIs, whereas first-line results are dismal. Avelumab maintenance in patients obtaining disease control with chemotherapy has achieved the highest survival rates. Conclusions: ICIs improve survival after platinum-based chemotherapy. Avelumab maintenance represents a new practice-changing treatment. The combinations of ICIs and other compounds, such as FGFR-inhibitors, antibody-drug conjugates, and anti-angiogenic drugs, represent promising therapeutic approaches. Biomarkers with predictive roles and sequencing strategies are warranted for best patient selection.

Searching for a harmonious survival: the experience of quality of life of urological cancer survivors

PURPOSE

This study aimed to analyze the experience of quality of life for urological cancer survivors.

METHODS

This is a qualitative narrative research based on the experience-centered approach. Twenty-one semi-structured face-to-face interviews were conducted with 12 survivors of urological cancer at different survival seasons. Participants were recruited from the convenience sampling. The thematic analysis approach was used to analyze the data. The findings are presented as narrative syntheses. The standards for reporting qualitative research (SPQR) were used in this study.

RESULTS

Two narrative syntheses were constructed: (1) Rupture in the different dimensions of QoL; and (2) QoL: Searching for a harmonious survival, each presenting their respective sub-themes. After the rupture in the different dimensions of QoL, the survivors resigned themselves and searched for a harmonious survival despite the physical, social, and psychological changes imposed by cancer treatments. Survivors achieved a new meaning of QoL with the support of family, hope, and spirituality.

CONCLUSIONS

The results highlight the changes experienced by survivors in different dimensions of QoL and the search for harmonious survival. Based on QoL experience reported in this study, health professionals can plan survival care and interventions that mitigate the consequences of treatment on QoL.

Health-related quality of life in bladder cancer patients: bladder cancer-specific instruments and domains. Part 2

PURPOSE OF REVIEW

Several instruments have been designed to evaluate health-related quality of life (HRQoL) in patients with bladder cancer (BC). However, they vary in purpose, domains, and quality. To identify QoL instruments that have been validated for BC patients and to critically assess their domains and limitations.

RECENT FINDINGS

Of the 11 instruments identified, seven have been externally validated. Of these, four can be used across all disease states; two are available for QoL assessment in patients with non-muscle invasive bladder cancer (NMIBC); and the European Organisation for Research and Treatment of Cancer (EORTC) module is intended for use together with a generic cancer-specific tool. Of the three instruments available to assess QoL in patients with muscle invasive bladder cancer (MIBC), EORTC Quality of Life Questionnaire-Bladder Cancer Muscle Invasive30 (QLQ-BLM30) and Functional Assessment of Cancer Therapy-Bladder-Cystectomy (FACT-Bl-Cys) need to be used each with their respective generic core questionnaire, whereas Ileal Orthotopic Neobladder-Pro Questionnaire is intended only to evaluate patients who have received an orthotopic neobladder.The core domains assessed by these instruments include social functioning, mental health, physical function, urinary function and sexual function.

SUMMARY

No optimal BC-specific QoL instruments exist. Multiple cancer- and BC-specific instruments are required to cover each of the relevant domains. Selected tools should be reviewed within the context of specific research objectives.

Avelumab first-line maintenance in locally advanced or metastatic urothelial carcinoma: Applying clinical trial findings to clinical practice

Although urothelial carcinoma (UC) is considered a chemotherapy-sensitive tumor, progression-free survival and overall survival (OS) are typically short following standard first-line (1L) platinum-containing chemotherapy in patients with locally advanced or metastatic disease. Immune checkpoint inhibitors (ICIs) have antitumor activity in UC and favorable safety profiles compared with chemotherapy; however, trials of 1L ICI monotherapy or chemotherapy + ICI combinations have not yet shown improved OS vs chemotherapy alone. In addition to direct cytotoxicity, chemotherapy has potential immunogenic effects, providing a rationale for assessing ICIs as switch-maintenance therapy. In the JAVELIN Bladder 100 phase 3 trial, avelumab administered as 1L maintenance with best supportive care (BSC) significantly prolonged OS vs BSC alone in patients with locally advanced or metastatic UC that had not progressed with 1L platinum-containing chemotherapy (median OS, 21.4 vs 14.3 months; hazard ratio, 0.69 [95% CI, 0.56-0.86]; P = 0.001). Efficacy benefits were seen across various subgroups, including recipients of 1L cisplatin- or carboplatin-based chemotherapy, patients with PD-L1+ or PD-L1- tumors, and patients with diverse characteristics. Results from JAVELIN Bladder 100 led to the approval of avelumab as 1L maintenance therapy for patients with locally advanced or metastatic UC that has not progressed with platinum-containing chemotherapy. Avelumab 1L maintenance is also included as a standard of care in treatment guidelines for advanced UC with level 1 evidence. This review summarizes the data that supported these developments and discusses practical considerations for administering avelumab maintenance in clinical practice, including patient selection and treatment management.

Patient-Reported Outcomes and Health-Related Quality of Life Following Radiotherapy for Bladder Cancer

Bladder cancer is the 11th most common cancer in the UK and with an ageing population the incidence is increasing. There is a relative lack of prospective quality of life (QoL) data evaluating the impact of the illness and treatment on QoL and patient-reported outcomes (PROs). Here we evaluate the available tools to assess QoL and PROs, and summarise the published data evaluating outcomes in patients treated with radiotherapy for muscle-invasive disease. We also discuss some of the recently completed studies and those ongoing that will help to shape future care and assist in decision making for patients and their clinicians.

Patient-Reported Outcomes, Health-Related Quality of Life, and Clinical Outcomes for Urothelial Cancer Patients Receiving Chemo- or Immunotherapy: A Real-Life Experience

Patients with urothelial cell carcinoma (UCC) often have comorbidities, which cause trouble for the completion of oncological treatment, and little is known about their quality of life (QoL). The aim of the present study was to obtain and describe patient-reported outcomes (PRO) and QoL data from UCC patients in the treatment for locally advanced muscle-invasive or metastatic UCC. A total of 79 patients with UCC completed four questionnaires (EORTC QLQ-C30, QLQ-BLM30, HADS, and select PRO-CTCAE™ questions) once weekly during their treatment. From those, 26 patients (33%) underwent neoadjuvant treatment for local disease while 53 patients (67%) were treated for metastatic disease. Of all patients, 54% did not complete the planned treatment due to progression, nephrotoxicity, death, or intolerable symptoms during treatment. The five most prevalent PRO-CTCAE grade ≥ 2 symptoms were frequent urination (37%), fatigue (35%), pain (31%), dry mouth (23%), and swelling of the arms or legs (23%). The baseline mean overall QoL was 61 (±SD 24) for all patients (neoadjuvant (73, ±SD 19) and metastatic (54, ±SD 24)) and remained stable over the course of treatment for both groups. A stable overall QoL was observed for the patients in this study. More than half of the patients did not, however, complete the planned treatment. Further supportive care is warranted for bladder cancer patients.

Development of Sarcopenia in Patients With Bladder Cancer: A Systematic Review

OBJECTIVE

Sarcopenia is known to influence cancer-related complications and overall survival. However, the effect of cancer treatment on the development or progression of sarcopenia is relatively unknown. The primary aim of this systematic review was to determine the prevalence and development of sarcopenia among people with bladder cancer.

DATA SOURCES

A systematic search was performed in PubMed, Web of Science, and EMBASE. Studies with ≥2 assessments of sarcopenia were eligible for inclusion. Five retrospective cohorts were included with a total of 438 participants. The baseline prevalence of sarcopenia across studies varied from 25% to 69% and post-treatment prevalence from 50% to 81%. The average loss of muscle mass was 2.2% to 10% during a time course of 3 to 12 months.

CONCLUSION

The prevalence of sarcopenia markedly increased during cancer treatment in patients with bladder cancer. Further research into the effect of different treatment regimens on the development of sarcopenia, and how these changes might affect functional capacity and survival is needed.

IMPLICATIONS FOR NURSING PRACTICE

The development of sarcopenia is important to understand because of its negative affect on quality of life, complications, and mortality. Further, understanding how sarcopenia develops during treatment could potentially strengthen nurses' future care plans for patients with bladder cancer.

Effect of neoadjuvant chemotherapy on health-related quality of life in patients with muscle-invasive bladder cancer: results from JCOG0209, a randomized phase III study

BACKGROUND

Although neoadjuvant chemotherapy provides survival benefits in muscle-invasive bladder cancer, the impact of neoadjuvant chemotherapy on health-related quality of life has not been investigated by a randomized trial. The purpose of this study is to compare health-related quality of life in patients with muscle-invasive bladder cancer who received neoadjuvant chemotherapy followed by radical cystectomy or radical cystectomy alone based on patient-reported outcome data.

METHODS

Patients were randomized to receive two cycles of neoadjuvant methotrexate, doxorubicin, vinblastine, and cisplatin followed by radical cystectomy or radical cystectomy alone. Health-related quality of life was measured using the Functional Assessment of Cancer Therapy-Bladder (version 4) questionnaire before the protocol treatments, after neoadjuvant chemotherapy, after radical cystectomy and 1 year after registration.

RESULTS

A total of 99 patients were analysed. No statistically significant differences in postoperative health-related quality of life were found between the arms. In the neoadjuvant chemotherapy arm, the scores after neoadjuvant chemotherapy were significantly lower than the baseline scores in physical well-being, functional well-being, Functional Assessment of Cancer Therapy-General total, weight loss, diarrhoea, appetite, body appearance, embarrassment by ostomy appliance and total Functional Assessment of Cancer Therapy-Bladder. However, there was no difference in scores for these domains, except for embarrassment by ostomy appliance, between the two arms after radical cystectomy and 1 year after registration.

CONCLUSIONS

Although health-related quality of life declined during neoadjuvant chemotherapy, no negative effect of neoadjuvant chemotherapy on health-related quality of life was apparent after radical cystectomy. These data support the view that neoadjuvant chemotherapy can be considered as a standard of care for patients with muscle-invasive bladder cancer regarding health-related quality of life.

Psychotropic medication utilisation in adult cancer patients in China: A cross-sectional study based on national health insurance database

Background

Psychotropic medications are useful to treat psychiatric disorders which are frequently underdiagnosed and undertreated in cancer patients. Evidence on utilisation of psychotropic medications in cancer patients was absent in China. This study aimed to analyse the prevalence and the potential predictors of psychotropic medication use in adult cancer patients in China.

Methods

We analysed cross-sectional data from the China Health Insurance Association database in 2015-2017, which contained health care utilisation information for a national representative sample of basic medical insurance beneficiaries. Cancer patients aged above 18 were identified by International Classification of Disease 10th revision code C00-C97. Psychotropic medications were defined following the Anatomical Therapeutic Chemical codes: antipsychotics (N05A), anxiolytics (N05B), hypnotics and sedatives (N05C), and antidepressants (N06A, N06CA). We calculated the prevalence of psychotropic medication use in cancer patients, and applied multivariable logistic regression to identify its potential predictors.

Findings

A total of 260,364 adults with cancer were identified in the database, of which 48,111 (18•5%) were prescribed at least one psychotropic medication comprising antipsychotics (3763, 1•4%), anxiolytics (15,902, 6•1%), hypnotics and sedatives (37,040, 14•2%), and antidepressants (2379, 0•9%). Patients with solid tumours had higher prevalence of psychotropic medication use than patients with lymphoid and hematopoietic malignancies (e.g. female genital organs, adjusted odds ratio (OR)=2•25, 95%CI=2•09-2•44). The prevalence of psychotropic medication use in cancer patients in the Eastern region was significantly higher than those of cancer patients in the Western regions (OR=2•33, 95%CI=2•27-2•40). Compared with the Urban Rural Resident Basic Medical Insurance beneficiaries, cancer patients covered by the Urban Employee Basic Medical Insurance were more likely to use psychotropic medications (OR=1•18, 95%CI=1•15-1•20). Midazolam was the most frequently used psychotropic (21,728, 45•2%), and flupentixol-melitracen was the most commonly used antidepressant (1176, 2•4%) among all psychotropic medication users in the sample.

Interpretation

The prevalence of psychotropic medication use in Chinese adult cancer patients was inequitable. Further attention will be needed to be paid to the mental health of cancer patients in China.

Health-related quality of life in the randomized phase 3 study of ramucirumab plus docetaxel versus placebo plus docetaxel in platinum-refractory advanced urothelial carcinoma (RANGE)

BACKGROUND

To evaluate patient-reported outcomes with ramucirumab plus docetaxel, a regimen which improved progression-free survival in platinum-refractory advanced urothelial carcinoma (aUC).

METHODS

RANGE-a randomized, double-blinded, phase 3 trial in patients with platinum-refractory aUC. Ramucirumab (10 mg/kg) plus docetaxel (75 mg/m2) or placebo plus docetaxel were administered every 21 days until disease progression or unacceptable toxicity. Patients received maximum 10 cycles of docetaxel. European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) and EuroQoL five-dimensions (EQ-5D-5L) were administered at baseline, start of each cycle, and 30-day follow-up visit. A ≥ 10-point change in QLQ-C30 scores was considered meaningful. Rates of improved/stable scores were compared between treatment arms using Fisher's exact test. Time to deterioration (TtD) was estimated and compared using Kaplan-Meier estimation and log-rank test.

RESULTS

Of the 530 patients, ~ 97% patients in each arm provided baseline QLQ-C30 data. On-treatment compliance was ≥ 88% for first 8 cycles. Mean baseline QLQ-C30 scores were similar between arms, with global quality of life (QoL), fatigue, pain, and insomnia having greatest impairment. Postbaseline rates of improved/stable QLQ-C30 scores were similar between treatment arms except for greater improvement in pain score with ramucirumab. TtD of QLQ-C30 scales favored ramucirumab arm. Baseline EQ-5D-5L index and visual analogue scale scores were similar between arms, followed by relatively stable on-treatment scores. EQ-5D-5L scores worsened at post-discontinuation follow-up visit.

CONCLUSIONS

Ramucirumab plus docetaxel did not negatively impact QoL compared with docetaxel alone in platinum-refractory aUC. Improved TtD and tumor associated rates of pain favored ramucirumab treatment.

Health-related quality of life overview after different curative treatment options in muscle-invasive bladder cancer: an umbrella review

PURPOSE

This umbrella review aims to evaluate the quality, summarize and compare the conclusions of systematic reviews investigating the impact of curative treatment options on health-related quality of life (HRQoL) in muscle-invasive bladder cancer (MIBC).

METHODS

The Cochrane Library, MEDLINE, Embase and Web of Science were searched independently by two authors from inception until 06 January 2020. Systematic reviews and meta-analyses assessing the impact of any curative treatment option on HRQol in MIBC patients were eligible. Risk of bias was assessed using the AMSTAR 2 tool.

RESULTS

Thirty-two reviews were included. Robot-assisted RC with extracorporeal urinary diversion and open RC have similar HRQoL (n = 10). Evidence for pelvic organ-sparing RC was too limited (n = 2). Patients with a neobladder showed better overall and physical HRQoL outcomes, but worse urinary function in comparison with ileal conduit (n = 17). Bladder-preserving radiochemotherapy showed slightly better urinary and sexual but worse gastro-intestinal HRQoL outcomes in comparison with RC patients (n = 6). Quality of the reviews was low in more than 50% of the available reviews and most of the studies included in the reviews were nonrandomized studies.

CONCLUSION

This umbrella review gives a comprehensive overview of the available evidence to date.

Patient reported symptoms associated with quality of life during chemo- or immunotherapy for bladder cancer patients with advanced disease

BACKGROUND

Bladder cancer (BC) patients with advanced disease have poor outcomes. The use of patient-reported outcomes (PROs) could lead to improvements in symptom management and hence quality of life (QoL). The aim of this study is to report correlations between selected PROs and QoL and thus to present symptoms that influence QoL. Identification of these symptoms during treatment can lead to earlier symptom management and thus secure improvements in QoL.

METHODS

BC patients in chemo- or immunotherapy for locally advanced or metastatic disease reported weekly PROs for the duration of their treatment. The PROs included EORTC QLQ-C30 and QLQ-BLM30 and 45 selected PRO-CTCAE items. Spearman's correlation analysis was performed for all PRO-CTCAE items and QLQ-C30 global QoL and subdomains.

RESULTS

In this study, 78 BC patients reported 724 questionnaires. Spearman's analysis showed significant correlations between almost all PRO-CTCAE items and the expected domain of QoL. The PRO-CTCAE items with the strongest correlations with QoL were anxiety (F, frequency item) and emotional function (rs  = -0.603, P < .0001), concentration (S, severity item) and cognitive function (rs  = -0.704, P < .0001), discouraged (F) and emotional function (rs  = -0.659, P < .0001), fatigue (S) and role function (rs  = -0.659, P < .0001) and sad (F) and emotional function (rs  = -0.711, P < .0001). The weakest correlations were found for the PRO-CTCAE items urinary frequency, incontinence and urge, all with variations in the direction and significance of the correlations.

CONCLUSIONS

This study delivers information on which PROs may influence QoL for patients in clinical trials or daily clinic. Psychological issues have a strong impact on QoL and should be dealt with during treatment to secure the best possible QoL for BC patients.

Influence of pretreatment quality of life on prognosis in patients with urothelial carcinoma

BACKGROUND

We investigated the association between the pretreatment quality of life (QOL) and overall survival (OS) in patients with urothelial carcinoma (UC), as the influence of pretreatment QOL on prognosis remains unclear in patients with localized and metastatic UC.

METHODS

Between June 2013 and May 2019, we retrospectively investigated 205 patients with UC who received radical cystectomy or nephroureterectomy for non-metastatic UC (M0 group) or systemic chemotherapy for metastatic UC (M1 group). Patients answered the European Organization for the Research and Treatment of Cancer Quality-of-Life Questionnaire C30 (QLQ-C30) before the treatments. Patients were stratified into two groups: QOL high and low according to the optimal cutoff scores which were defined by receiver operating characteristic curve. Inverse probability of treatment weighting (IPTW)-adjusted multivariate Cox regression analyses were performed to investigate the clinical implication of pretreatment QOL score on OS in patients with UC.

RESULTS

The number of patients in the M0 and M1 groups was 125 and 80, respectively. Optimal cutoff values in global, fatigue, pain, appetite loss, physical, and role scores were < 50, > 33, > 33, > 16, < 80, and < 67, respectively. IPTW-adjusted multivariate Cox regression analyses revealed that appetite loss score indicated a significantly poorer OS in the M1 group. No significant association of QOL with OS was observed in the M0 group.

CONCLUSION

Pretreatment QOL of appetite loss may predict poor prognosis of patients with metastatic UC.

Patient-reported outcomes item selection for bladder cancer patients in chemo- or immunotherapy

Background

Selection of specific patient-reported outcomes (PROs) for cancer patients requires careful consideration to the purpose and population at aim. Here we report the process of choosing which items to include in a bladder cancer population in chemo- or immunotherapy based on the Patient-Reported Outcomes Version of the Common Terminology Criteria of Adverse Events (PRO-CTCAE).

Methods

Initial PRO-CTCAE symptoms were chosen through 1) medical record audit 2) patient interviews 3) summary of product characteristics from European Medicines Agency and Food and Drug Administration for the applied chemotherapies, and 4) toxicity reporting from Phase 2 and 3 trials for immunotherapies applied in patients with urothelial cancer. The selected questions were applied in a prospective cohort of 78 bladder cancer patients receiving chemo- or immunotherapy at Rigshospitalet and Herlev Hospital, Denmark. Symptoms tested in this population were selected for the final module if they appeared in ≥3 of the following groupings a) the most prevalent PRO-CTCAE symptoms grade ≥ 2 overall during treatment b) the PRO-CTCAE symptoms reported in conjunction with hospital admissions or mentioned in focus group interviews discussing which symptoms were prevalent in this patient group with specialized c) nurses or d) physicians. The authors also included symptoms in the final module if they were present in two of the above groups and defined as actionable by clinicians.

Results

From the initial selection of PRO-CTCAE symptoms, a total of 45 PRO-CTCAE symptoms explored by 84 PRO-CTCAE questions were retrieved. Through the second selection process based on the described criteria, the study group agreed on 15 PRO-CTCAE symptoms explored by 30 PRO-CTCAE items to be appropriate and relevant for the bladder population during medical oncological treatment.

Conclusions

The selection of disease specific PROs in a bladder cancer population was feasible. The process revealed several steps of selection needed in order to reach a final module for clinical application.

Patient perspectives of vigorous intensity aerobic interval exercise prehabilitation prior to radical cystectomy: a qualitative focus group study

PURPOSE

Preoperative cardiopulmonary fitness is increasingly being recognized as an important factor influencing postoperative recovery outcomes in cancer patients. The aim of this study was to explore patient perspectives of preoperative high intensity aerobic interval exercise before radical cystectomy.

MATERIALS AND METHODS

Focus groups involving a purposive convenience sample of patients with bladder cancer (N = 14; mean age ± SD: 72.3 ± 6.0 years) were undertaken in a hospital education department. Data were analyzed using Framework analysis.

RESULTS

Participants identified physical (e.g., fitness) psychological (e.g., preparing for their operation) and social (e.g., peer support) benefits of the program. Key motivational factors for engaging in exercise prehabiliation were identified as social support, previous exercise experience and objective measures of progression. The need for clear information from healthcare providers to ensure that patients are adequately prepared for sessions was highlighted.

CONCLUSIONS

This qualitative study provides new insights into the perspectives and experiences of patients with bladder cancer regarding participation in preoperative vigorous intensity aerobic exercise. The study yielded novel perceptions on the physical, psychological and social health benefits accruing from the exercise program and patient views on program design features, which are important for informing future interventions and implementation strategies.IMPLICATIONS FOR REHABILITATIONA preoperative high intensity aerobic interval exercise program before radical cystectomy provides physical, psychological and social benefits to individuals living with bladder cancer.Supervised exercise, objective improvement, and peer and family support all contribute to motivation to engage with preoperative high intensity aerobic interval exercise.Individuals may require support post-radical cystectomy in order to continue with exercise due to the uncertainty around this.
