Modifiable lifestyle behaviours impact the health‐related quality of life of bladder cancer survivors

Abstract

Objective

To examine health behaviours in bladder cancer survivors including physical activity (PA), body mass index, diet quality, smoking and alcohol consumption, and to explore their relationship with health‐related quality of life (HRQoL).

Subjects/Patients and Methods

Cross‐sectional questionnaire packages were distributed to bladder cancer survivors (muscle‐invasive bladder cancer [MIBC] and non‐muscle‐invasive bladder cancer [NMIBC]) aged >18 years, and proficient in English. Lifestyle behaviours were measured using established measures/questions, and reported using descriptive statistics. HRQoL was assessed using the validated Bladder Utility Symptom Scale, and its association with lifestyle behaviours was evaluated using analysis of covariance (ancova ) and multivariate regression analyses.

Results

A total of 586 participants completed the questionnaire (52% response rate). The mean (SD) age was 67.3 (10.2) years, and 68% were male. PA guidelines were met by 20% ( = 117) and 22.7% ( = 133) met dietary guidelines. In all, 60.9% ( = 357) were overweight/obese, and the vast majority met alcohol recommendations ( = 521, 92.5%) and were current non‐smokers ( = 535, 91.0%). Health behaviours did not differ between MIBC and NMIBC, and cancer treatment stages. Sufficient PA, healthy diet, and non‐smoking were significantly associated with HRQoL, and the number of health behaviours participants engaged in was positively associated with HRQoL ( < 0.001).

Conclusion

Bladder cancer survivors are not meeting guidelines for important lifestyle behaviours that may improve their overall HRQoL. Future research should investigate the impact of behavioural and educational interventions for health behaviours on HRQoL in this population.

Efficacy of vibegron, a novel β3‐adrenoreceptor agonist, on severe urgency urinary incontinence related to overactive bladder: post hoc analysis of a randomized, placebo‐controlled, double‐blind, comparative phase 3 study

Abstract

Objective

To evaluate the efficacy of a novel and selective β3‐adrenoreceptor agonist vibegron on urgency urinary incontinence (UUI) in patients with overactive bladder (OAB).

Patients and Methods

post hoc analysis was performed in patients with UUI (>0 episodes/day) who were assigned to receive vibegron or placebo in a vibegron phase 3 study. Patients were subclassified into mild/moderate (>0 to <3 UUI episodes/day) or severe UUI (≥3 UUI episodes/day) subgroup. Changes from baseline in number of UUI episodes/day, in number of urgency episodes/day, and in voided volume/micturition were compared between the groups. The percentage of patients who became UUI‐free (‘diary‐dry’ rate) and the response rate (percentage of patients with scores 1 [feeling much better] or 2 [feeling better] assessed by the Patient Global Impression scale [PGI]) were evaluated.

Results

Changes in numbers of UUI episodes at week 12 in the vibegron 50 mg, vibegron 100 mg and placebo groups, respectively, were −1.35, −1.47 and −1.08 in all patients, −1.04, −1.13 and −0.89 in the mild/moderate UUI subgroup, and −2.95, −3.28 and −2.10 in the severe UUI subgroup. The changes were significant in the vibegron 50 and 100 mg groups vs placebo regardless of symptom severity. Change in number of urgency episodes/day was significant in the vibegron 100 mg group vs placebo in all patients and in both severity subgroups. In the vibegron 50 mg group, a significant change vs placebo was observed in all patients and in the mild/moderate UUI subgroup. Change in voided volume/micturition was significantly greater in the vibegron 50 and 100 mg groups vs placebo in all patients, as well as in the both severity subgroups. Diary‐dry rates in the vibegron 50 and 100 mg groups were significantly greater vs placebo in all patients and in the mild/moderate UUI subgroup. In the severe UUI subgroup, however, a significant difference was observed only in the vibegron 50 mg group. Response rates assessed by the PGI were significantly higher in the vibegron groups vs placebo in all patients and in the both severity subgroups. Vibegron administration, OAB duration ≤37 months, mean number of micturitions/day at baseline <12.0 and mean number of UUI episodes/day at baseline <3.0 were identified as factors significantly associated with normalization of UUI.

Conclusions

Vibegron, a novel β3‐adrenoreceptor agonist, significantly reduced the number of UUI episodes/day and significantly increased the voided volume/micturition in patients with OAB including those with severe UUI, with the response rate exceeding 50%. These results suggest that vibegron can be an effective therapeutic option for OAB patients with UUI.

Prostate cancer in kidney transplant recipients – a nationwide register study

Abstract

Objective

To investigate whether post‐transplantation immunosuppression negatively affects prostate cancer outcomes in male kidney transplant recipients.

Patients and Methods

We used the Swedish Renal Register and the National Prostate Cancer Register to identify all kidney transplantation recipients diagnosed with prostate cancer in Sweden 1998–2016. After linking these registers with Prostate Cancer Database Sweden (PCBaSe), a case‐control study was designed to compare time period and risk category‐specific probabilities of a prostate cancer diagnosis amongst kidney transplantation recipients versus the male general population. The registers did not include information about the specific immunosuppression agent used in all transplantation recipients. Data from PCBaSe were used to compare prostate cancer characteristics at diagnosis and survival for patients with prostate cancer with versus without a kidney transplant. Propensity score matching, Cox regression analysis and Fisher’s exact test were used and 95% confidence intervals (CIs) calculated.

Results

Almost half of the 133 kidney transplantation recipients were transplanted before the mid‐1990s, when PSA testing became common. The transplant recipients were not more likely than age‐matched control men to be diagnosed with any (odds ratio [OR] 0.84, 95% CI 0.70–0.99) or high‐risk or metastatic prostate cancer (OR 0.84, 95% CI 0.62–1.13). None of the ORs for the different categories of prostate cancer increased with time since transplantation. Cancer characteristics at the time of diagnosis and cancer‐specific survival were similar amongst transplant recipients and the control group of 665 men diagnosed with prostate cancer without a kidney transplant.

Conclusions

This Swedish nationwide, register‐based study gave no indication that immunosuppression after kidney transplantation increases the risk of prostate cancer or adversely affects prostate cancer outcomes. The study suggests that men with untreated low‐grade prostate cancer can be accepted for transplantation.
