[PMID: 37892180 PMCID: PMC10604959 DOI: 10.3390/biom13101498] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 09/25/2023] [Accepted: 09/30/2023] [Indexed: 10/29/2023] Open
Abstract
Globally, bladder cancer (BC) is one of the ten most common tumors. Obesity is a worldwide problem associated with an increased BC risk. Considering that levels of leptin and/or its receptor are often deregulated in obese individuals, we hypothesized that they could contribute to BC. To test this hypothesis, we utilized a case-control study in which 116 patients with a confirmed diagnosis of BC and 116 controls were recruited. The serum levels of leptin and leptin receptor were measured. Patients and controls were also genotyped for SNPs in the LEP (rs7799039, rs791620, and rs2167270) and LEPR genes (rs1137100, rs1137101, and rs1805094). The univariate analysis indicated that BC patients had significantly higher levels of leptin and lower levels of leptin receptor (p < 0.05). Moreover, rs7799039 of LEP and rs1137101 of LEPR were associated with BC (p < 0.05). In the multivariate analysis, leptin receptor levels were protective (OR: 0.98, 95% CI = 0.97-0.99, p = 0.002) while the GG genotype of rs1137101 of LEPR increased BC risk (OR: 3.42, 95% CI = 1.27-9.20, p = 0.02). These findings highlight that lifestyle changes could be useful in preventing BC and that disturbances in energy metabolism could play a role in the pathobiology of BC.

Abstract
Background Observational studies have suggested that obesity is associated with the risk of bladder cancer (BCa). However, their causal relationship remains unclear. This study aimed to prove the causal relationship between obesity and the risk of BCa by using Mendelian randomization. Methods Single-nucleotide polymorphisms (SNPs) correlated with body fat indexes were screened from several genome-wide association studies (GWAS) with more than 300,000 individuals. Summary-level genetic data of BCa-related GWAS were obtained from a European cohort with a sample size of 218,792. An inverse-variance-weighted (IVW) method was used as the major MR analysis. The MR-Egger regression, IVW regression, leave-one-out test, and MR-Pleiotropy Residual Sum and Outlier methods were used to test the reliability and stability of MR results. Results Genetically predicted per 1-SD increase in body fat indexes (whole body fat mass, and the right leg, left leg, right arm, left arm, and trunk fat mass) were associated with increased BCa risk with values of 51.8%, 77.9%, 75.1%, 67.2%, 59.7%, and 36.6%, respectively. Sensitivity analyses suggested that the genetically determined risk effect of obesity on BCa was stable and reliable. Conclusions Our study provided powerful evidence to support the causal hypothesis that the genetically predicted high body fat mass was associated with a risk increase for BCa. The finding is a new idea for drawing up prevention strategies for BCa.

Abstract
Background The incidence of kidney, bladder, and prostate cancer ranked ninth, sixth, and third in male cancers respectively, meanwhile, the incidence of testicular cancer also increased gradually in the past 30 years. Objective To study and present estimates of the incidence, mortality, and disability of kidney, bladder, prostate, and testicular cancer by location and age from 1990 to 2019 and reveal the mortality risk factors of them. Materials The Global Burden of Diseases Study 2019 was used to obtain data for this research. The prediction of cancer mortality and incidence was based on mortality-to-incidence ratios (MIRs). The MIR data was processed by logistic regression and adjusted by Gaussian process regression. The association between the socio-demographic index and the incidence or disease burden was determined by Spearman's rank order correlation. Results Globally in 2019, there were 371,700 kidney cancer cases with an age-standardized incidence rate (ASIR) of 4.6 per 100,000, 524,300 bladder cancer cases, with an ASIR of 6.5 per 100,000, 1,410,500 prostate cancer cases with an ASIR of 4.6 per 100,000 and 109,300 testicular cancer incident cases with an ASIR of 1.4 per 100,000, the ASIR of these four cancers increased by 29.1, 4, 22, and 45.5% respectively. The incidence rate of the four cancers and the burden of kidney cancer were positively correlated with the socio-demographic index (SDI), regions with a higher SDI faced more of a burden attributable to these four cancers. High body-mass index has surpassed smoking to be the leading risk factor in the past thirty years for kidney cancer mortality. Smoking remained the leading risk factor for cancer-related mortality for bladder cancer and prostate cancer and the only risk factor for prostate cancer. However, the contribution of high fasting plasma glucose to bladder cancer mortality has been increasing. Conclusion The incidence of bladder, kidney, prostate, and testicular cancer is ever-increasing. High-income regions face a greater burden attributable to the four cancers. In addition to smoking, metabolic risk factors may need more attention.

Abstract
Glioblastoma multiforme (GBM) is a malignant primary tumor type of the central nervous system (CNS). This type of brain tumor is rare and is responsible for 12-15% of all brain tumors. The typical survival rate of GBM is only 12 to 14 months. GBM has a poor and unsatisfactory prognosis despite advances in research and therapeutic interventions via neurosurgery, radiation, and chemotherapy. The molecular heterogeneity, aggressive nature, and occurrence of drug-resistant cancer stem cells in GB restricts the therapeutic efficacy. Interestingly, the CNS tumors in children are the second most usual and persistent type of solid tumor. Since numerous research studies has shown the association between obesity and cancer, childhood obesity is one of the potential reasons behind the development of CNS tumors, including GBM. Obesity in children has almost reached epidemic rates in both developed and developing countries, harming children's physical and mental health. Obese children are more likely to face obesity as adults and develop non-communicable diseases such as diabetes and cardiovascular disease as compared to adults with normal weight. However, the actual origin and cause of obesity are difficult to be pointed out, as it is assumed to be a disorder with numerous causes such as environmental factors, lifestyle, and cultural background. In this narrative review article, we discuss the various molecular and genetic drivers of obesity that can be targeted as potential contributing factors to fight the development of GBM in children.

Abstract
There is considerable evidence of a positive association between the incidence of type 2 diabetes mellitus (T2DM) and obesity with bladder cancer (BCa), with the link between T2DM and obesity having already been established. There also appear to be potential associations between Pleckstrin homology domain containing S1 (PLEKHS1) and the Insulin-like Growth Factor (IGF) axis. Seven literature searches were carried out to investigate the backgrounds of these potential links. PLEKHS1 is a candidate biomarker in BCa, with mutations that are easily detectable in urine and increased expression seemingly associated with worse disease states. PLEKHS1 has also been implicated as a potential mediator for the onset of T2DM in people with obesity. The substantial evidence of the involvement of IGF in BCa, the role of the IGF axis in obesity and T2DM, and the global prevalence of T2DM and obesity suggest there is scope for investigating the links between these components. Preliminary findings on the relationship between PLEKHS1 and the IGF axis signal possible associations with BCa progression. This indicates that PLEKHS1 plays a role in the pathogenesis of BCa that may be mediated by members of the IGF axis. Further detailed research is needed to establish the relationship between PLEKHS1 and the IGF axis in BCa and determine how these phenomena overlap with T2DM and obesity.

Abstract
Background To explore the overall trends of incidence rate (IR), mortality and survival outcomes of patients with urothelial bladder cancer (UBC) over the past two decades. Methods Patients diagnosed with UBC from 1993 to 2012 were extracted from the Surveillance, Epidemiology and End Result (SEER) 18 database. Baseline characteristics and treatment types of included patients were collected retrospectively. Moreover, the age-adjusted IRs and annual percent changes (APCs) were obtained. Afterwards, we calculated the standardized mortality ratios (SMRs) for bladder cancer (BC), cardiovascular disease (CVD) and all-cause mortality by comparing UBC cases with the general population. Finally, survival outcomes of UBC patients were analyzed and compared. Results A total of 220,405 UBC patients were identified, including 167,036 (75.79%) male patients and 53,369 (24.21%) female patients, with an average age of 70.84 years old. Most patients were White (89.85%), with older age (71.67%, >65 years old), lower T stage diseases (78.11%, < T2) and lower median household income (55.37%). When compared with patients diagnosed between 1993 and 2002, those diagnosed between 2003 and 2012 had older age (mean: 71.15 vs. 70.16 years old, P<0.001), higher proportion of men (76.22% vs. 74.83%, P<0.001) and lower median household income (56.69% vs. 52.50%, P<0.01). Overall, the IR of UBC increased slightly before 2003 and maintained a stable trend of about 20 per 100,000 person-years after 2003. Additionally, CVD was recognized as an important cause of death (COD) of UBC patients. UBC patients were 44.5 times more likely to die of CVD when compared with the general population. Furthermore, the 3-, 5- and 10-year overall survival (OS) and cancer-specific survival (CSS) rates were 0.709, 0.609 and 0.421, and 0.861, 0.831 and 0.789, respectively. Finally, survival outcomes between patients diagnosed in the two periods (1993–2002 vs. 2003–2012) were not significantly different. Conclusions The IR of UBC increased slightly before 2003 and remained stable after 2003. UBC patients had higher CVD burden than the general population. Hence, cardiovascular health should be emphasized to reduce mortality after UBC diagnosis. Lastly, survival outcomes of UBC patients in the last two decades showed no significant difference.

Abstract
Background: Adult overweight is a potential bladder cancer (BC) risk factor, but little is known about size earlier in life.Aim: To investigate if birth weight, childhood body mass index (BMI), height and growth are associated with adult BC.Subjects and methods: Anthropometric information from birth and ages 7-13 on 315,763 individuals born 1930-1989 in the Copenhagen School Health Records Register was linked to national registers. Hazard ratios (HR) and 95% confidence intervals (CI) were estimated by Cox regression.Results: 1145 individuals (839 men) were diagnosed with BC. Sex differences were not detected. Childhood BMI had positive associations and height had inverse associations with BC; at age 13, HR = 1.10 (95% CI: 1.02-1.18) per BMI z-score and HR = 0.94 (95% CI: 0.89-1.00) per height z-score. A pattern of above-average increases in BMI from 7 to 13 years had higher hazards of BC than average increases. Above-average growth in height was not significantly associated with BC. Compared with birth weights of 3.5 kg, low (2.5 kg) and high (4.5 kg) values were associated with increased hazards of BC; HR = 1.26 (95% CI: 1.01-1.58) and HR = 1.36 (95% CI: 1.09-1.70), respectively.Conclusions: A high BMI, a short height, excess BMI gain in childhood and low and high birth weights are associated with increased hazards of BC.

Abstract
Physical activity is associated with decreased risk for many cancers. Studies on the association between physical activity and risk of bladder cancer are limited, and findings are inconsistent. Postmenopausal women (mean age = 63.3) were recruited into the Women's Health Initiative from 1993 to 1998. Self-reported baseline information on physical activity and other covariates were available in 141 288 participants. Incident bladder cancer cases were collected through 2018 and centrally adjudicated. Hazard ratios (HRs) and 95% confidence intervals (CIs) were determined by Cox proportional hazard regression models. Effect modification due to smoking was assessed. During an average of 18.5 years of follow-up, 817 bladder cancer cases were identified. Compared to physically inactive women, those who engaged in ≥15 MET-hours/week of total physical activity, ≥8.75 MET-hours/week of walking or ≥11.25 MET-hours/week of moderate to vigorous physical activity had lower risk of bladder cancer (HR = 0.74, 95% CI: 0.59-0.94, P for linear trend = .02; HR = 0.79, 95% CI: 0.63-0.98, P for linear trend = .03; and HR = 0.76, 95% CI: 0.61-0.94, P for linear trend = .02, respectively). No effect modification was found by smoking status (P for interaction = .06, 0.91 and 0.27, respectively). We found that total physical activity, walking and moderate to vigorous physical activity were inversely associated with bladder cancer incidence among postmenopausal women in a dose-response manner. Physical activity may play a potential role in the primary prevention of bladder cancer. Further studies with objective measurements of physical activity are needed to confirm these findings.

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% (n = 117) and 22.7% (n = 133) met dietary guidelines. In all, 60.9% (n = 357) were overweight/obese, and the vast majority met alcohol recommendations (n = 521, 92.5%) and were current non‐smokers (n = 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 (P < 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.

Abstract
Background Little is known about occupational disparities in bladder cancer survival. Methods Using data from a population‐based cancer registry (1970‐2016), we identified 3593 patients with incident bladder cancer diagnosed during 1970‐2011 who completed occupational information. The patients were followed for 5 years (median follow‐up time 5.0 years). Their longest‐held occupations at incident bladder cancer diagnosis were classified according to a national standardized classification. Hazard ratios (HRs) and 95% confidence intervals (CIs) for overall death were estimated by Cox proportional hazard model, adjusted for age, sex, and year of diagnosis. Clerical workers served as the reference group. Results Overall prognosis was fair in this population (5‐year overall survival, 61.9%). Compared with patients in clerical jobs, survival was poorer for those in professional and managerial jobs (mortality HR 1.36; 95% CI 1.09‐1.69), sales and service jobs (HR 1.25, 95% CI 1.01‐1.56), construction jobs (HR 1.83, 95% CI 1.40‐2.38), and manufacturing jobs (HR 1.32, 95% CI 1.05‐1.66), as well as those not actively employed (HR 1.27, 95% CI 1.02‐1.58). A similar pattern was observed in the subgroup analyses restricted to male patients as well as additional analyses adjusted for potential prognostic variables (eg, stage) with multiple imputation. Conclusion We documented occupational disparities in bladder cancer survival in Japan. However, the pattern of disparity did not favor highest occupational groups.

Abstract
BACKGROUND Egypt is among the countries with the highest incidence of bladder cancer (BC). Adipokines involved in BC development. This study aimed to examine the diagnostic and prognostic roles of irisin in BC through its function as an adipokine. PATIENTS AND METHODS This study included 150 subjects; 75 patients newly diagnosed as BC and 75 apparently healthy subjects. Serum irisin levels were quantified by enzyme-linked immunosorbent assay. RESULTS Serum irisin levels exhibited significantly lower levels in BC patients compared to controls (1.07 [0.51-1.96] and 1.8 [0.5-2.44] µg/mL), respectively (P < 0.001). Serum irisin was positively correlated with BMI (r = 0.386, P = 0.001) and negatively correlated with serum cholesterol (r = -0.58, P < 0.0001). Irisin had 74.7% sensitivity and 90.7% specificity at a cutoff point of ≤1.2 µg/mL. Serum irisin levels reduction can predict the BC stages, when adjusted for BMI and serum cholesterol level, serum irisin had an adjusted odds ratio of 14 (P = 0.001). Low serum irisin patients had a higher mortality rate when compared to those with high levels (38.2% vs 5%). CONCLUSION BC patients had significantly lower levels of serum irisin. Serum irisin showed acceptable performance criteria in BC diagnosis. It had a limited role in BC grading but showed a decreasing trend in different BC stages. Serum irisin seems to be an excellent diagnostic and prognostic marker for BC.

Abstract
Bladder cancer is one of the most frequent cancers in high-income countries. Information on bladder cancer in Italy is scattered across scientific literature and institutional and educational resources and no attempt has been made yet to organize and summarize this information across various sources of available data. We, therefore, present herein a critical literature review of recent epidemiological and healthcare data, including patients' unmet needs. We undertook a critical review of the scientific and grey literature by exploring several different databases and search browsers. Available official statistics indicate a high burden of bladder cancer in Italy, where this neoplasm has one of the highest incidences worldwide and, in consideration of its relatively high survival, it ranks 4th in cancer prevalence. The limited therapeutic options for muscle-invasive and advanced/metastatic urothelial cancer are one of the major unmet needs for patients with this neoplasm, in Italy and worldwide. Advances in cancer immunotherapy and in understanding molecular biology of bladder cancer are, however, rapidly altering the therapeutic landscape for targeted subgroups of patients with advanced/metastatic disease. Other unmet needs include the low quality of life after radical cystectomy, the lack of widespread clinical pathway schemes to improve and standardize the quality of care and low Italian patients empowerment. Bladder cancer represents a health burden in Italy, with high incidence and prevalence rates, and important unmet needs for patients, including the limited therapeutic options for advanced/metastatic cancers, the low quality of life after radical cystectomy, the lack of widespread clinical pathway schemes, and the low patients empowerment.

Abstract
BACKGROUND Bladder cancer is the ninth most common cancer in the world. OBJECTIVES This study aimed to determine the correlation between age-standardized incidence rates of bladder cancer and some risk factors in Asian countries through an extensive ecological analysis. METHODS This ecological study evaluated the correlation between age-standardized incidence rates of bladder cancer and obesity, overweight, physical inactivity, and tobacco use in 30 Asian countries. To determine the factors that were significantly related to age-standardized incidence rate of bladder cancer, a univariate analysis was performed using simple linear regression. In the next step, variables with p-values less than 0.25 were entered into a multivariate linear regression model. RESULTS The incidence of bladder cancer was higher in countries with higher prevalence of overweight (r2 = 0.36, p < 0.001), obesity (r2 = 0.34, p = 0.001), current daily tobacco use (r2 = 0.17, p = 0.03), and physical inactivity (r2 = 0.13, p = 0.04). The results of multiple regression analysis indicated a direct correlation between the incidence of bladder cancer and overweight (β = 0.15, p < 0.001) and current daily tobacco use (β = 0.21, p = 0.001). CONCLUSIONS There was a significant relationship between the incidence of bladder cancer and overweight and current daily tobacco use. Further epidemiological studies are needed to confirm this relationship.

Abstract
PURPOSE Investigators have reported inconsistent findings regarding associations between body mass index (BMI) and bladder cancer risk, and they have postulated that sex steroids mediate such associations. We assessed the impact of BMI on the relationship between bladder cancer risk and combinations of age at first childbirth, parity, and age at menopause, among Egyptian women. METHODS We used data from our multicenter case-control study of 419 cases and 786 controls in logistic regression models to estimate adjusted odds ratios (AORs) and 95% confidence intervals (CIs) of such associations. RESULTS Age > 18 years at first childbirth and parity ≤ 6 were significantly associated with bladder cancer risk, which was higher when both factors (AOR = 2.31, 95% CI = 1.55-3.43) and age at menopause < 45 years (AOR = 3.51, 95% CI = 1.88-6.55) were present. Early menopause was associated with higher bladder cancer risk in obese (AOR = 2.90, 95% CI = 1.40-5.98) but not normal weight women (AOR = 0.98, 95% CI = 0.58-1.65; Pinteraction = 0.11), and the risk was greatest when both first childbirth at age > 18 years and parity ≤ 6 were present (AOR = 7.60, 95% CI = 1.84-31.35); however, overweight and obesity were associated with significantly lower bladder cancer risk (AOR = 0.59, 95% CI = 0.43-0.81, and AOR = 0.26, 95% CI = 0.18-0.38, respectively). CONCLUSION Body mass index appears to modify bladder cancer risk in Egyptian women after menopause by slightly enhancing the risk associated with low estrogen exposure among the obese only. Longitudinal studies of the BMI role in bladder malignancy in this distinctive population are required.

Abstract
Bladder cancer is one of the top 5 most common cancers diagnosed in the U.S. It is also one of the most expensive cancers to treat through the life course given its high rate of recurrence. While cigarette smoking and occupational exposures have been firmly established as risk factors, it is less certain whether modifiable lifestyle factors such as diet and physical activity play roles in bladder cancer etiology and prognosis. This literature review based on a PubMed search summarizes the research to date on key dietary factors, types of physical activity, and smoking in relation to bladder cancer incidence, and discusses the potential public health implications for formalized smoking cessation programs among recently diagnosed patients. Overall, population-based research in bladder cancer is growing, and will be a key platform to inform patients diagnosed and living with bladder cancer, as well as their treating clinicians, how lifestyle changes can lead to the best outcomes possible.

Abstract
CONTEXT Haematuria is a common urological presentation associated with patient anxiety and clinically relevant underlying pathology. However, the prevalence and pathophysiology of haematuria following sporting exercise is less well documented. OBJECTIVES This review paper seeks to clarify the prevalence of microscopic and macroscopic haematuria in association with sporting exercise reported in the literature, and the pathophysiology behind it. We review the relation of haematuria to injury to the urinary tract in sport, as well as the incidence of underlying disease, urological and incidental, following investigation for exercise-induced haematuria. EVIDENCE ACQUISITION A non-systematic literature review was conducted of articles and studies using the Pubmed database. Articles were selected with preference for the highest level of evidence available, with relevant data extracted, analysed, and summarised. Supplementary information was collected by cross-referencing the reference lists. EVIDENCE SYNTHESIS Multiple studies have shown that clinically significant haematuria is common after exercise. Physiological changes occurring during exercise result in increased glomerular permeability and microscopic haematuria in up to 95% of cases. The degree of haematuria is related to the intensity of the exercise. However, participating in contact sports increases the risk of macroscopic haematuria. Red cell haemolysis and rhabdomyolysis also play a role in urine discolouration following exercise and can be present in 30%. Haematuria following exercise-related trauma is regarded an important indication for further urological investigation. Haematuria may be absent in 44% of cases of urological injury. Renal trauma accounts for 80% of urological trauma, with 30% of these being due to sporting activity. Incidental findings on computed tomography for haematuria are common, with 50% showing positive extraurinary findings. Incidental malignancy, however, is rare. CONCLUSIONS Haematuria is common following exercise and results from physiological changes and contact-related trauma to the urinary tract. All cases of haematuria should be investigated as underlying trauma and extraurinary disease are common incidental findings on investigation. PATIENT SUMMARY Blood in the urine following exercise is a common phenomenon and occurs due to vascular responses to sports and trauma as well as blood and muscle cell breakdown. Although it may not be present in all cases of trauma, blood in the urine should be investigated due to the risk of discovering underlying injury to the urinary tract and other incidental findings.

Abstract
OBJECTIVES Leptin and its receptor (LEPR) are key players in the regulation of energy balance and body weight control and act as a growth factor for specific organs in both normal and disease states. However, LEPR accumulation may be involved in carcinogenesis, progression, and metastasis in many cancers. This study evaluated the clinical significance of LEPR expression in upper tract urothelial carcinoma (UTUC). MATERIALS AND METHODS LEPR expression was examined in 110 tissue samples from patients with UTUC, using immunohistochemistry, and an analysis was performed to identify evidence of association between LEPR expression and different clinicopathologic variables. RESULTS LEPR expression was significantly correlated with patients with increased body mass index (P < .001) and high serum creatinine levels (P = .005). We found, using the log-rank test, that high LEPR expression was associated with poor recurrence-free (P = .009) and cancer-specific survival (P = .001). This finding was supported by our results using Cox regression analysis, which showed that LEPR expression was an independent predictor of poor recurrence-free survival (hazard ratio = 2.55; P = .011) and cancer-specific survival (hazard ratio = 2.26; P = .006). CONCLUSIONS Our findings indicate that LEPR expression is a potential biomarker for predicting patient survival in UTUC. Further study is necessary to investigate the role of LEPR in carcinogenesis of UTUC.

Abstract
BACKGROUND The aim of this study was to investigate modifiable lifestyle factors of smoking, exercise, and obesity with bladder cancer mortality. PATIENTS AND METHODS We used mortality-linked data from the National Health Information Survey from 1998 through 2006. The primary outcome was bladder cancer-specific mortality. The primary exposures were self-reported smoking status (never- vs. former vs. current smoker), self-reported exercise (dichotomized as "did no exercise" vs. "light, moderate, or vigorous exercise in ≥ 10-minute bouts"), and body mass index. We utilized multivariable adjusted Cox proportional hazards regression models, with delayed entry to account for age at survey interview. RESULTS Complete data were available on 222,163 participants, of whom 96,715 (44%) were men and 146,014 (66%) were non-Hispanic whites, and among whom we identified 83 bladder cancer-specific deaths. In multivariate analyses, individuals who reported any exercise were 47% less likely (adjusted hazard ratio [HRadj], 0.53; 95% confidence interval [CI], 0.29-0.96; P = .038) to die of bladder cancer than "no exercise". Compared with never-smokers, current (HRadj, 4.24; 95% CI, 1.89-9.65; P = .001) and former (HRadj, 2.95; 95% CI, 1.50-5.79; P = .002) smokers were 4 and 3 times more likely, respectively, to die of bladder cancer. There were no significant associations of body mass index with bladder cancer mortality. CONCLUSION Exercise decreases and current smoking increases the risk of bladder cancer-specific mortality. These data suggest that exercise and smoking cessation interventions may reduce bladder cancer death.

Abstract
PURPOSE Diet, physical activity, and smoking cessation are modifiable lifestyle factors that have been shown to improve health-related quality of life (HRQOL) in many cancer survivors. Our objective was to systematically review the literature on the associations between lifestyle factors, namely diet, physical activity, smoking status, and HRQOL in bladder cancer survivors. METHODS We queried PubMed, EMBASE, and Cochrane libraries. Two reviewers reviewed abstracts independently, and a third reviewer arbitrated disagreements. A descriptive analysis was performed. Quality assessment was conducted using the Newcastle-Ottawa Quality Assessment Scale for observational studies and the Cochrane Risk of Bias Tool for clinical trials. RESULTS We identified 1167 publications in the initial search, of which 9 met inclusion criteria for full-text review. We were able to obtain data on the outcomes of interest for 5 publications. A total of 1288 patients who underwent treatment for bladder cancer were included. Three studies were observational by design and two were randomized controlled trials. Physical activity was addressed by 4 studies, smoking status by 2 studies, and diet by 1 study. CONCLUSIONS The review highlights the limited evidence around lifestyle factors and quality of life in bladder cancer survivors. There is some evidence for a positive association between HRQOL and physical activity, but insufficient evidence upon which to draw conclusions about the effects of consuming fruits and vegetables or non-smoking. IMPLICATIONS FOR CANCER SURVIVORS There is limited evidence to support a positive association between health-related quality of life and physical activity, but insufficient evidence upon which to base any conclusions about consumption of fruits and vegetables or smoking cessation in bladder cancer survivors.

Abstract
With recent medical advances in diagnosis and treatment, the increasing numbers of long-term survivors of breast cancer is considerable and has resulted in the expansion of scientific research to include examination of lifestyle modifications as means of prevention of recurrence, new breast cancer events, and mortality. The objective of this report is to review randomized controlled trials (RCTs) including diet and/or exercise interventions on breast cancer recurrence in women with a history of breast cancer as well as pertinent recent epidemiologic evidence. Implicated biologic mechanisms are discussed to elucidate the impact of diet and exercise on disease recurrence.
