Knowledge of the harms of tobacco use among patients with bladder cancer

Bladder cancer patient and provider perspectives on smoking cessation

BACKGROUND

Smoking is the most common risk factor for bladder cancer and is associated with adverse clinical and cancer-related outcomes. Increasing understanding of the patient and provider perspectives on smoking cessation may provide insight into improving smoking cessation rates among bladder cancer survivors. We sought to inform strategies for providers promoting cessation efforts and help patients quit smoking.

METHODS

Using a modified Delphi process with multidisciplinary input from bladder cancer providers, researchers, and a patient advocate, 2 surveys were created for bladder cancer patients and providers. Surveys included multiple-choice questions and free answers. The survey was administered electronically and queried participants' perspectives on barriers and facilitators associated with smoking cessation. Survey responses were anonymous, and participants were provided with a $20 Amazon gift card for participating. Patients were approached through the previously established Bladder Cancer Advocacy Network (BCAN) Patient Survey Network, an online bladder cancer patient and caregiver community. Providers were recruited from the Society of Urologic Oncology (SUO) and the Large Urology Group Practice Association (LUGPA).

RESULTS

From May to June 2021, 308 patients and 103 providers completed their respective surveys. Among patients who quit smoking, most (64%) preferred no pharmacologic intervention ("cold turkey") followed by nicotine replacement therapy (28%). Repeated efforts at cessation commonly occurred, and 67% reported making more than one attempt at quitting prior to eventual smoking cessation. Approximately 1 in 10 patients were unaware of the association between bladder cancer and smoking. Among providers, 75% felt that barriers to provide cessation include a lack of clinical time, adequate training, and reimbursement concerns. However, 79% of providers endorsed a willingness to receive continuing education on smoking cessation.

CONCLUSIONS

Bladder cancer patients utilize a variety of cessation strategies with "cold turkey" being the most used method, and many patients make multiple attempts at smoking cessation. Providers confront multiple barriers to conducting smoking cessation, including inadequate time and training in cessation methods; however, most would be willing to receive additional education. These results inform future interventions tailored to bladder cancer clinicians to better support provider efforts to provide smoking cessation counseling.

Urologists' Perceptions and Practices Related to Patient Smoking and Cessation: A National Assessment From the 2021 American Urological Association Census

OBJECTIVE

To assess urologists' perceptions and practices related to smoking and smoking cessation.

MATERIALS AND METHODS

Six survey questions were designed to assess beliefs, practices, and determinants related to tobacco use assessment and treatment (TUAT) in outpatient urology clinics. These questions were included in an annual census survey (2021) offered to all practicing urologists. Responses were weighted to represent the practicing US population of nonpediatric urologists (N = 12,852). The primary outcome was affirmative responses to the question, "Do you agree it is important for urologists to screen for and provide smoking cessation treatment to patients in the outpatient clinic?" Practice patterns, perceptions, and opinions of optimal care delivery were assessed.

RESULTS

In total, 98% of urologists agreed (27%) or strongly agreed (71%) that cigarette smoking is a significant contributor to urologic disease. However, only 58% agreed that TUAT is important in urology clinics. Most urologists (61%) advise patients who smoke to quit but do not provide additional cessation counseling or medications or arrange follow-up. The most frequently identified barriers to TUAT were lack of time (70%), perceptions that patients are unwilling to quit (44%), and lack of comfort prescribing cessation medications (42%). Additionally, 72% of respondents stated that urologists should provide a recommendation to quit and refer patients for cessation support.

CONCLUSION

TUAT does not routinely occur in an evidence-based fashion in outpatient urology clinics. Addressing established barriers and facilitating these practices with multilevel implementation strategies can promote tobacco treatment and improve outcomes for patients with urologic disease.

Smoking Cessation and Tobacco-related Risk Perceptions among People with and without a Diagnosis of Cancer

BACKGROUND

Little is known about how cancer diagnosis and tobacco-related risk perceptions are associated with smoking behavior.

METHODS

We used data from Waves (W) 1-3 (2013-2016) of the Population Assessment of Tobacco and Health Study to analyze longitudinal smoking behavior among adults who were current smokers and not previously diagnosed with cancer at baseline (W1; N = 7,829). The outcome was smoking cessation as of follow-up (W3). Explanatory variables were sociodemographics, other tobacco product use, adult at first cigarette, tobacco dependence, cancer diagnosis after baseline, and tobacco-related risk perceptions [cigarette harm perception, worry that tobacco products will damage one's health ("worry"), belief that smoking causes cancer ("belief"), and nondaily smoking harm perception].

RESULTS

Cessation was significantly associated with baseline worry (OR = 1.26; 95% confidence interval, 1.13-1.40), follow-up cigarette harm perception [OR = 2.01 (1.77-2.29)], and follow-up belief [OR = 1.40 (1.20-1.63)]. Cessation was inversely associated with follow-up (W3) worry, and this association was stronger among those without a cancer diagnosis (OR = 0.37 without cancer; OR = 0.76 among individuals diagnosed with cancer; interaction P = 0.001).

CONCLUSIONS

Cessation is associated with tobacco-related risk perceptions, with different perceptions contributing in unique ways. Cessation is predicted by baseline worry but is inversely associated with worry at follow-up, suggesting that perhaps cessation has alleviated worry. The latter finding was stronger among respondents not diagnosed with cancer.

IMPACT

Associations between cancer diagnosis, tobacco-related risk perceptions, and smoking behavior may inform the development of evidence-based smoking cessation interventions.

Epidemiology, Screening, and Prevention of Bladder Cancer

CONTEXT

Bladder cancer (BC) represents a significant health problem due to the potential morbidity and mortality associated with disease burden, which has remained largely unaltered over time.

OBJECTIVE

To provide an expert collaborative review and describe the incidence, prevalence, and mortality of BC and to evaluate current evidence for BC screening and prevention.

EVIDENCE ACQUISITION

Data on the estimated incidence and mortality of BC for 2020 in 185 countries were derived from the International Agency for Research on Cancer GLOBOCAN database. A review of English-language articles published over the past 5 yr was conducted using PubMed/MEDLINE to identify risk factors in addition to contemporary evidence on BC screening and prevention.

EVIDENCE SYNTHESIS

BC is the tenth most common cancer worldwide, with 573 278 cases in 2020. BC incidence is approximately fourfold higher in men than women. Tobacco smoking remains the principal risk factor, accounting for approximately 50% of cases. There is insufficient evidence to recommend routine BC screening. However, targeted screening of high-risk individuals (defined according to smoking history or occupational exposure) may reduce BC mortality and should be the focus of prospective randomized trials. In terms of disease prevention, smoking cessation represents the most important intervention, followed by a reduction in exposure to occupational and environmental carcinogens.

CONCLUSIONS

BC confers a significant disease burden. An understanding of BC epidemiology and risk factors provides an optimal foundation for disease prevention and the care of affected patients.

PATIENT SUMMARY

Bladder cancer is the tenth most common cancer worldwide and is approximately four times more common among men than among women. The main risk factors are tobacco smoking, followed by exposure to carcinogens in the workplace or the environment. Routine screening is not currently recommended, but may be beneficial in individuals at high risk, such as heavy smokers. Primary prevention is extremely important, and smoking cessation represents the most important action for reducing bladder cancer cases and deaths.

Systematic review of smoking relapse rates among cancer survivors who quit at the time of cancer diagnosis

BACKGROUND

Tobacco cessation, at the time of cancer diagnosis, has been associated with better oncologic outcomes. Cancer diagnosis has been shown to serves as a "teachable moment," inspiring tobacco cessation. However, the sustainability of abstinence from smoking is understudied. Similarly, there is a paucity of data regarding the utility of behavioral/pharmacologic intervention to support continued smoking cessation.

METHODS

A systematic literature review was conducted in August 2021 with no date limits. Relevant studies that reported tobacco smoking relapse rates for patients who quit at the time of cancer diagnosis were included. Our literature search identified 1620 articles and 29 met inclusion criteria. The primary endpoint of the study was smoking relapse rate. Secondary outcome was a descriptive assessment of behavioral and pharmacologic interventions to promote continued cessation. Exploratory outcomes included a regression analysis to examine associations between study factors and relapse rates.

RESULTS

There were 3021 smokers who quit at the time of cancer diagnosis. Weighted overall relapse rate for the study population was 44 % (range 5-57 %). Interventions to support smoking cessation were employed in 17 of the 29 included studies and protocols were heterogenous, including behavioral, pharmacologic, or mixed intervention strategies. Exploratory analysis demonstrated no association between relapse rates and publication year, gender, or study type. Relapse rates were indirectly associated with age (p = .003), suggesting that younger patients were more likely to relapse.

CONCLUSION

The sustainability of smoking cessation after a cancer diagnosis is understudied, and existing literature is difficult to interpret due to heterogeneity. Relapse rates remain significant and, although many studies have included the employment of an intervention to promote continued cessation, few studies have measured the effect of a protocolized intervention to support abstinence.

Awareness of Smoking as a Risk Factor in Bladder Cancer: Results from the Prospective FinnBladder 9 Trial

BACKGROUND

Data regarding patient education and smoking habits among bladder cancer patients are scarce.

OBJECTIVE

To investigate awareness of smoking as a risk factor for bladder cancer among bladder cancer patients.

DESIGN, SETTING, AND PARTICIPANTS

This is a substudy of a prospective, randomized, multicenter phase 3 trial (FinnBladder 9, NCT01675219). The data were collected at baseline and after 12 mo of follow-up between 2012 and 2020.

INTERVENTION

Patients completed a comprehensive nonvalidated questionnaire on smoking in relation to bladder cancer.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

The outcomes measured were patient-reported awareness of smoking as a risk factor for bladder cancer, and the effect of smoking on bladder cancer-related recurrence, progression, and death. Parametric data were compared using Student's t test and proportions using Fischer's exact test. Factors affecting baseline awareness of the effect of smoking cessation on bladder cancer were studied using logistic regression.

RESULTS AND LIMITATIONS

Of the 411 patients randomized, 370 completed the baseline questionnaire and were included in the analysis. At baseline, 44% of patients were uncertain if smoking was a risk factor for bladder cancer. Patient awareness of the fact that smoking cessation reduces the risk of bladder cancer recurrence increased from 86% to 92% after 12 mo of follow-up (p = 0.038). Older patients and patients with recurrent bladder cancer had significantly less knowledge about the effect of smoking on bladder cancer recurrence, progression, and mortality. A major limitation is that the response rate was lower at the 12-mo follow-up visit than at baseline.

CONCLUSIONS

Awareness of smoking as a bladder cancer risk factor is low. Older patients and patients with recurrent bladder cancer may need special attention regarding education.

PATIENT SUMMARY

We looked at outcomes for smoking-related patient education on bladder cancer in a Finnish population. We conclude that older patients and patients with recurrent bladder cancer may need to be educated on this subject.

Using a multilevel implementation strategy to facilitate the screening and treatment of tobacco use in the outpatient urology clinic: A prospective hybrid type I study

BACKGROUND

Urologists frequently treat patients for tobacco-related conditions but infrequently engage in evidence-based practices (EBPs) that screen for and treat tobacco use. Improving the use of EBPs will help to identify smokers, promote cessation, and improve patients' health outcomes.

METHODS

A prospective type I hybrid effectiveness-implementation study was performed to test the feasibility and effectiveness of using a multilevel implementation strategy to improve the use of tobacco EBPs. All urology providers at outpatient urology clinics within the Veterans Health Administration Greater Los Angeles and all patients presenting for a new urology consultation were included. The primary outcome was whether a patient was screened for tobacco use at the time of consultation. Secondary outcomes included a patient's willingness to quit, chosen quit strategy, and subsequent engagement in quit attempts.

RESULTS

In total, 5706 consecutive veterans were seen for a new consultation during the 30-month study period. Thirty-six percent of all visits were for a tobacco-related urologic diagnosis. The percentage of visits that included tobacco use screening increased from 18% (before implementation) to 57% in the implementation phase and to 60% during the maintenance phase. There was significant provider-level variation in adherence to screening. Of all screened patients, 38% were willing to quit, and most patients chose a "cold turkey" method; 22% of the patients elected referral to a formal smoking cessation clinic, and 24% chose telephone counseling. Among those willing to quit, 39% and 49% made a formal quit attempt by 3 and 6 months, respectively.

CONCLUSIONS

A strategy that includes provider education and a customized clinical decision support tool can facilitate provider use of tobacco EBPs in a surgery subspecialty clinic.

Internalized stigma among cancer patients enrolled in a smoking cessation trial: The role of cancer type and associations with psychological distress

PURPOSE

Cancer patients who smoke may experience significant stigma due both to their disease, and negative attitudes and beliefs regarding smoking. We investigated whether internalized stigma differed between currently smoking cancer patients diagnosed with lung or head and neck cancers, other smoking related cancers, and non smoking-related cancers, and whether internalized stigma was associated with psychological distress.

METHODS

This cross-sectional analysis used baseline data on 293 participants enrolled in a multi-site randomized smoking cessation intervention trial of patients with recently diagnosed cancer. Internalized stigma was assessed using five Internalized Shame items from the Social Impact of Disease Scale. Smoking-related cancers included lung, head and neck, esophageal, bladder, kidney, liver, pancreatic, colorectal, anal, small intestinal, gastric, and cervical. We used multivariable linear regression to examine whether mean internalized stigma levels differed between individuals with lung and head and neck cancers, other smoking-related cancers, and non smoking-related cancers, adjusting for potential confounders. We further examined the association of internalized stigma with depression, anxiety, and perceived stress, overall and among cancer type groups.

RESULTS

Thirty-nine percent of participants were diagnosed with lung or head and neck cancer, 21% with another smoking-related cancer, and 40% with a non smoking-related cancer. In multivariable-adjusted models, participants with lung or head and neck cancers (11.6, 95% confidence intervals (CI) = 10.8-12.2; p < 0.0001) or other smoking-related cancers (10.7, 95% CI = 9.8-11.7; p = 0.03) had higher mean internalized stigma scores compared to those non-smoking-related cancers (9.3, 95% CI = 8.6-10.0). We observed similar positive associations between internalized stigma and depressive symptoms, anxiety, and perceived stress among participants with smoking-related and non smoking-related cancers.

CONCLUSIONS

Among smokers, those with smoking-related cancers experienced the highest levels of internalized stigma, and greater internalized stigma was associated with greater psychological distress across cancer types. Providers should assess patients for internalized and other forms of stigma, refer patients for appropriate psychosocial support services, and address stigma in smoking cessation programs.

Best practices for assessing and reporting tobacco use in urology oncology practice and research

Tobacco use is the cause of several urologic cancers. Persistent use after diagnosis is associated with worse cancer-specific, quality of life, and overall mortality outcomes. Cigarette smoking remains the most common form of tobacco use despite significant population-level decline over the past few decades. The burden of smoking-related urologic disease is under appreciated by urologists and patients which has resulted in gaps in clinical care and limitations to research progress. We sought to summarize evidence-based practices and guideline recommendations for assessing and reporting tobacco use in the clinical and research settings. With a focus on smoking, our two primary goals are: 1) to promote the adoption of standardized and validated measures of tobacco use and 2) to highlight evidence-based strategies for urologists to use in clinical practice.

Prevalence and Correlates of Successful Smoking Cessation in Bladder Cancer Survivors

OBJECTIVE

To assess the prevalence and correlates of successful smoking cessation in bladder cancer survivors.

MATERIALS AND METHODS

A population-based sample of bladder cancer survivors diagnosed over a 3 year period was obtained from the California Cancer Registry. Respondents completed a survey about their tobacco use and attempts at smoking cessation. Contingency tables and logistic regression analyses were used to evaluate for correlates of successful smoking cessation.

RESULTS

Of total survey respondents, 19% (151 of 790) were active smokers at bladder cancer diagnosis and made up our analytic cohort. The majority of included respondents were male, older than 60, and had smoked for >40 years prior to diagnosis. After diagnosis, 76% (115 of 151) of active smokers made a quit attempt and 56% (65 of 115) were successful. Success with smoking cessation was more frequent among those who attempted to quit around the time of initial bladder cancer diagnosis. The majority (66%) of successful quitters did so "cold turkey" without pharmacotherapy or behavioral therapy. After adjustment for demographic and tobacco-related factors, quit attempts specifically motivated by the bladder cancer diagnosis were highly associated with smoking cessation success (OR 11.6; 95% CI 3.73-35.8). Use of pharmacologic or behavioral therapies in the quit attempt were not significantly associated with successful smoking cessation.

CONCLUSION

Our data underscore the importance of motivation, timing, and the role of the urologist in the quit attempts of bladder cancer survivors. Emphasis should be placed on ensuring the newly diagnosed make a timely quit attempt informed by the causal role of smoking in their malignancy.

The impact of smoking on radical cystectomy complications increases in elderly patients

BACKGROUND

Smoking, the most common risk factor for bladder cancer (BC), is associated with increased complications after radical cystectomy (RC), poorer oncologic outcomes, and higher mortality. The authors hypothesized that the effect of smoking on the probability of major complications increases with increasing age among patients who undergo RC.

METHODS

The authors analyzed the American College of Surgeons National Surgical Quality Improvement Program database (2011-2017), identified all patients undergoing RC using Current Procedural Terminology codes, and formed two groups according to smoking status (active smoker and nonsmoker [included former and never-smokers]). Patient characteristics and 30-day postoperative complications using the Clavien-Dindo Classification (CDC) were assessed. A multivariable logistic regression model was constructed that included age, sex, race, body mass index, operative time, comorbidities, chemotherapy status, and type of diversion with major complications (CDC ≥III) as the outcome variable, and explored the interaction between age and smoking status.

RESULTS

A total of 10,528 patients underwent RC, including 22.8% who were active smokers. The authors identified an interaction between age and smoking status (P = .045). Older patients were found to experience a stronger smoking effect than younger patients with regard to the probability of major complications. The risk of a major complication was the same for 50-year-old nonsmokers and smokers, but it increased from 17.8% to 21.7% for 70-year-old nonsmokers and smokers, respectively (P < .001).

CONCLUSIONS

Up to 20% of patients who undergo RC are active smokers, and these individuals have an increased risk of major complications. The effect of smoking is stronger with increasing age; the difference with regard to complications for smokers versus nonsmokers was found to increase substantially, wherein older smokers are at an especially high risk of complications.

Knowledge of bladder cancer in the French population: results of the EDIFICE 6 survey

OBJECTIVE

To assess awareness of bladder cancer (BCa) in France.

METHODS

The French nationwide observational survey EDIFICE 6 was conducted online (26 June-28 July 2017) in 12,046 individuals (age, 18-69 years). The present analysis focuses on laypersons' knowledge of the severity and frequency of BCa, signs and symptoms, associated risk factors and screening tests. Quantitative data were expressed as means and standard deviation, and categorical data as percentages.

RESULTS

Analyses were conducted on 11,313 questionnaires. Among the top five acknowledged risk factors for BCa, tobacco was ranked as having the second lowest impact (5.9/10 [2.5]). Only 28% of the study population were aware that active tobacco smoking is a major risk factor for BCa (rating ≥8/10); 61% of the study population was unaware of the existence of any signs or symptoms of BCa, and 69% was not able to cite any of the most widely used diagnostic tests.

CONCLUSIONS

We found that the French population has a poor knowledge of BCa risk factors, early signs and diagnostic tests. Effective prevention of BCa requires dissemination of clear information and prevention messages to the lay population, focusing particularly on tobacco consumption and early signs of the disease.

Can Cancer Diagnosis Help in Quitting Tobacco? Barriers and Enablers to Tobacco Cessation Among Head and Neck Cancer Patients from a Tertiary Cancer Center in South india

BACKGROUND

Tobacco use contributes to almost 40% of the cancers in India. Considering the potential threat, many preventive measures have been instigated in the country. However, tobacco cessation for hospitalized cancer patients is an unexplored territory in India. This study aims to understand the quit status and to explore the reasons to quit or continue the use of tobacco after the diagnosis of head and neck cancer (HNC).

METHODS

HNC patients admitted between February and April 2016 were assessed for their tobacco use status. A DT was used to assess the psychological distress. Users were assessed for their readiness to quit and dependence on tobacco. An in-depth interview was conducted among 25 patients (seven current users and 18 recent quitters), and themes that emerged were discussed.

RESULTS

Of the 119 HNC patients, 71 were tobacco users and 48 had quit tobacco after the diagnosis. The reasons to quit were the perceived benefits of quitting, advice from the physicians, and awareness about cancer and its association with tobacco. In contrast, the reasons to continue the use of tobacco were attributed to coping mechanisms, nihilistic perception about the outcome of the cancer, and a lack of understanding about cancer and its association with tobacco.

CONCLUSION

The recent quitters comprehended the benefits of quitting and were able to prioritize their needs after the diagnosis. However, one-third of the HNC patients continued to use tobacco even after the diagnosis of cancer. Hence, tobacco cessation services need to be integrated into oncology services for achieving better treatment outcomes.

The interaction of gender and smoking on bladder cancer risks

PURPOSE OF REVIEW

Although smoking and gender are well-established bladder cancer (BCa) risk factors, a significant interaction with other risk factors could help in the identification of patterns for early detection and prevention strategies.

RECENT FINDINGS

Smoking appears to be more strongly associated with BCa risk in women than in men, which could be related to differences in metabolism, smoking behavior, exposure patterns, and DNA repair mechanisms. BMI is associated with a higher risk of BCa with negligible difference between genders. The risk for BCa is increased in postmenopausal women, specifically in women with earlier menopausal age (<45 years). Other potential risk factors such as alcohol, arsenic exposure, and particulate matter inhalation seem to affect the genders differently.Female smokers experience a higher risk of disease recurrence after bacillus Calmette-Guérin therapy than their male counterparts. Lastly, smoking appears to negatively affect the outcome of radiotherapy in women, but not that of men.

SUMMARY

Several lines of evidence point to an interaction between smoking and gender, whereas their impact on other potential risk factors remains to be elucidated. Identifying such differential effects could allow for gender-specific prevention, early detection, and treatment strategies.

Evaluating the cost of surveillance for non-muscle-invasive bladder cancer: an analysis based on risk categories

INTRODUCTION

Non-muscle-invasive bladder cancer (NMIBC) is a biologically heterogeneous disease and is one of the most expensive malignancies to treat on a per patient basis. In part, this high cost is attributed to the need for long-term surveillance. We sought to perform an economic analysis of surveillance strategies to elucidate cumulative costs for the management of NMIBC.

METHODS

A Markov model was constructed to determine the average 5-year costs for the surveillance of patients with NMIBC. Patients were stratified into low, intermediate, and high-risk groups based on the EORTC risk calculator to determine recurrence and progression rates according to each category. The index patient was a compliant 65-year-old male. A total of four health states were utilized in the Markov model: no evidence of disease, recurrence, progression and cystectomy, and death.

RESULTS

Cumulative costs of care over a 5-year period were $52,125 for low-risk, $146,250 for intermediate-risk, and $366,143 for high-risk NMIBC. The primary driver of cost was progression to muscle-invasive disease requiring definitive therapy, contributing to 81% and 92% of overall cost for intermediate- and high-risk disease. Although low-risk tumors have a high likelihood of 5-year recurrence, the overall cost contribution of recurrence was 8%, whereas disease progression accounted for 71%.

CONCLUSION

Although protracted surveillance cystoscopy contributes to the expenditures associated with NMIBC, progression increases the overall cost of care across all three patient risk groups and most notably for intermediate- and high-risk disease patients.

Influence of Gender and Age on the Willingness to Reduce Nicotine Consumption-Results of a Survey in Urological Cancer Patients (KRAUT Study)

PURPOSE

Our objective was to investigate whether patients with urologic tumors were aware of smoking as a risk factor for the development and progression of several urologic cancers and the extent of the medical education they had received. Another aim was to investigate whether gender or age influenced patients' willingness to change their smoking habits.

MATERIALS AND METHODS

Patients with histologically malignant urologic tumors were enrolled in our questionnaire-based study from September 2013 to December 2014 in 2 urology departments. Patients were asked about their smoking habits and their general understanding of the relationship between smoking and the onset of cancer (urologic cancer and lung cancer). Also, the extent of information they had acquired from a physician was assessed. The descriptive and oncologic data of the patients were recorded.

RESULTS

Of 258 enrolled patients, 186 (72.1%) had never had an informational discussion with a doctor about smoking and their urologic tumor disease. Of the 160 active and former smokers, only 45 (28.1%) were planning to stop or reduce smoking because of their tumor disease. The willingness to change smoking habits was greater for women, with a statistically significant difference (odds ratio, 5.59; P = .002). Younger patients aged <58 years were also more willing to reduce or stop smoking.

CONCLUSION

In our study, most patients with urologic cancer were unaware of smoking as the most probable cause of tumor development. The patients had not received proper counseling from doctors on smoking and the risk it poses for tumor progression. Efforts to balance compliance among the genders and age groups through risk-adapted counseling should be undertaken.

Perceptions of Continued Smoking and Smoking Cessation Among Patients With Cancer

PURPOSE

Continued smoking after a cancer diagnosis leads to poorer treatment outcomes, survival, and quality of life. We evaluated the perceptions of the effects of continued smoking on quality of life, survival, and fatigue among patients with cancer after a cancer diagnosis and the effects of these perceptions on smoking cessation.

PATIENTS AND METHODS

Patients with cancer from all disease subsites from Princess Margaret Cancer Centre (Toronto, Ontario) were surveyed between April 2014 and May 2016 for sociodemographic variables, smoking history, and perceptions of continued smoking on quality of life, survival, and fatigue. Multivariable regression models evaluated the association between patients' perceptions and smoking cessation and the factors influencing patients' perceptions of smoking.

RESULTS

Among 1,121 patients, 277 (23%) were smoking cigarettes up to 1 year before diagnosis, and 54% subsequently quit; 23% had lung cancer, and 27% had head and neck cancers. The majority felt that continued smoking after a cancer diagnosis negatively affected quality of life (83%), survival (86%), and fatigue (82%). Current smokers during the peridiagnosis period were less likely to perceive that continued smoking was harmful when compared with ex-smokers and never-smokers ( P < .01). Among current smokers, perceiving that smoking negatively affected quality of life (adjusted odds ratio [aOR], 2.68 [95% CI, 1.26 to 5.72]; P = .011), survival (aOR, 5.00 [95% CI, 2.19 to 11.43]; P < .001), and fatigue (aOR, 3.57 [95% CI, 1.69 to 7.54]; P < .001) were each strongly associated with smoking cessation. Among all patients, those with a greater smoking history were less likely to believe that smoking was harmful in terms of quality of life (aOR, 0.98 [95% CI, 0.98 to 0.99]; P < .001), survival (aOR, 0.98 [95% CI, 0.98 to 0.99]; P < .001), and fatigue (aOR, 0.99 [95% CI, 0.98 to 0.99]; P < .001).

CONCLUSION

The perceptions of continued smoking after a cancer diagnosis among patients with cancer are strongly associated with smoking cessation. Counseling about the harms of continued smoking in patients with cancer, and in particular among those who have lower risk perceptions, should be considered when developing a smoking cessation program.

What do patients with urothelial cancer know about the association of their tumor disease with smoking habits? Results of a German survey study

Purpose

Smoking represents a primary risk factor for the development of urothelial carcinoma (UC) and a relevant factor impacting UC-specific prognosis. Data on the accordant knowledge of UC-patients in this regard and the significance of physicians in the education of UC-patients is limited.

Materials and Methods

Eighty-eight UC-patients were enrolled in a 23-items-survey-study aimed to analyse patient knowledge and awareness of their tumor disease with smoking along with physician smoking cessation counselling.

Results

The median age of the study patients was 69 years; 26.1% (n=23), 46.6% (n=41), and 27.3% (n=24), respectively, were non-smokers, previous, and active smokers. Exactly 50% of active smokers reported a previous communication with a physician about the association of smoking and their tumor disease; however, only 25.0% were aware of smoking as main risk factor for UC development. Merely 33% of the active smokers had been prompted directly by their physicians to quit smoking. About 42% of active smokers had received the information that maintaining smoking could result in a tumor-specific impairment of their prognosis. Closely 29% of active and about 5% of previous smokers (during the time-period of active smoking) had been offered support from physicians for smoking cessation. No association was found between smoking anamnesis (p=0.574) and pack-years (p=0.912), respectively, and tumor stage of UC.

Conclusions

The results of this study suggest that the medical conversation of physicians with UC-patients about the adverse significance of smoking is limited. Implementation of structured educational programs for smoking cessation may be an opportunity to further enhance comprehensive cancer care.

The impact of advanced proteomics in the search for markers and therapeutic targets of bladder cancer

Bladder cancer is the most common cancer of the urinary tract and can be avoided through proper surveillance and monitoring. Several genetic factors are known to contribute to the progression of bladder cancer, many of which produce molecules that serve as cancer biomarkers. Blood, urine, and tissue are commonly analyzed for the presence of biomarkers, which can be derived from either the nucleus or the mitochondria. Recent advances in proteomics have facilitated the high-throughput profiling of data generated from bladder cancer-related proteins or peptides in parallel with high sensitivity and specificity, providing a wealth of information for biomarker discovery and validation. However, the transmission of screening results from one laboratory to another remains the main disadvantage of these methods, a fact that emphasizes the need for consistent and standardized procedures as suggested by the Human Proteome Organization. This review summarizes the latest discoveries and progress of biomarker identification for the early diagnosis, projected prognosis, and therapeutic response of bladder cancer, informs the readers of the current status of proteomic-based biomarker findings, and suggests avenues for future work.

Smoking-related genitourinary cancers: A global call to action in smoking cessation

Smoking is a known modifiable risk factor in the development of genitourinary malignancies. Although the association has long been supported by numerous research studies, the impact of smoking cessation on the decreased risk of genitourinary malignancies is less well studied. PubMed databases were searched using the terms smoking, smoking cessation, bladder cancer, kidney cancer, prostate cancer, penile cancer, testicular cancer, their synonyms, and also targeted manual searches to perform a literature review in order to summarize the benefits of cessation on disease progression and patient outcomes including survival and morbidities. Our review yielded substantial evidence highlighting the improved outcomes observed in those diagnosed with bladder, renal, and prostate cancers. The risk of bladder cancer is reduced by up to 60% in those who were able to quit for 25 years and the risk of kidney malignancy was reduced by 50% in those who abstained from smoking for 30 years. A similar trend of reduced risk was observed for prostate cancer with those who quit for more than 10 years, having prostate cancer mortality risks similar to those that never smoked. Although the data were encouraging for bladder, renal, and prostate malignancies, there are comparatively limited data quantifying the benefits of smoking cessation for penile and testicular cancers, highlighting an opportunity for further study. The role of urologists and their impact on their patients' likelihood to quit smoking shows more than half of urologists never discuss smoking cessation upon diagnosis of a malignancy. Most urologists said they did not provide cessation counseling because they do not believe it would alter their patients' disease progression. Studies show urologists have more influence at changing their patients' smoking behaviors than their primary care physicians. The diagnosis of cancer may lead to a teachable moment resulting in increased smoking quit rates. Furthermore, implementing a brief 5-minute clinic counseling session increases quit attempts and quit rates. Diagnosis of genitourinary cancers and the following appointments for treatment provide a unique opportunity for urologists to intervene and affect the progression and outcome of disease.

Urological disease and tobacco. A review for raising the awareness of urologists

CONTEXT

Smoking is the leading cause of preventable death in our community. Its relationship with urological disease is well documented.

OBJECTIVE

To present an updated review on the relationship between urological disease and tobacco consumption and the importance of involving urologists in smoking prevention.

ACQUISITION AND SYNTHESIS OF EVIDENCE

We conducted a review of current literature, primarily by searching PubMed and using as the main base the report on the consequences of smoking on health performed by the Surgeon General.

CONCLUSION

Urologists play an essential role in informing patients of the relationship between smoking and urological disease. It is the duty of every urologist to play a more active role in educating patients and promoting smoking cessation.

Natural biology and management of nonmuscle invasive bladder cancer

PURPOSE OF REVIEW

This article reviews the natural biology of noninvasive bladder cancer and its management strategies while summarizing the most recent advances in the field.

RECENT FINDINGS

Nonmuscle invasive bladder cancer (NMIBC) has a tendency to recur and progress. Risk stratification has helped triage patients but improved tools, including biomarkers, are still needed. Enhanced endoscopy with photodynamic imaging, narrow band imaging, optical coherence tomography and confocal laser endomicroscopy show promise for diagnosis, risk stratification and disease monitoring. Attempts at better treatment, especially in refractory high-risk cases, include the addition of intravesical hyperthermia, combination and sequential therapy with existing agents and the use of novel agents such as mycobacterial cell wall extract. New data are emerging regarding the potential role of active surveillance in low-risk patients.

SUMMARY

NMIBC represents a variety of disease states and continues to pose management challenges. As our understanding of tumor biology improves and technology advances, achieving better outcomes through individualized care may be possible.

Management of noninvasive bladder cancers

PURPOSE OF REVIEW

To summarize clinical management of nonmuscle-invasive bladder cancer (NMIBC) and discuss recent advances in the field.

RECENT FINDINGS

NMIBC remains a common and expensive clinical entity. Prevention, early detection, and risk-adapted treatment are the mainstays of clinical management, all of which may improve as a result of recent research. Photodynamic diagnosis has demonstrated improved detection of nascent disease, and specific clinical scenarios have been identified in which photodynamic diagnosis may improve clinical outcomes. New intravesical chemotherapeutic and immunotherapeutic agents challenge our current paradigm for intermediate/high-risk NMIBC and may delay need for cystectomy after bacillus Calmette-Guerin failure. Progress in risk stratification increasingly permits individualized management regimens for NMIBC.

SUMMARY

NMIBC includes many heterogeneous disease states with a variety of clinical behaviors that may evolve over time. Improved detection and risk stratification promise assignment of the optimal treatment option for an individual patient at a given time.

Underuse and underreporting of smoking cessation for smokers with a new urologic cancer diagnosis

BACKGROUND

Urothelial carcinoma of the bladder (UCB) or upper urinary tract (UCUT) and renal cell carcinoma (RCC) are smoking-related genitourinary (GU) malignancies. A new diagnosis of smoking-related GU cancer is an opportunity when smoking cessation interventions may have increased effectiveness. Underuse or underreporting of cessation tools in this setting represents potential for quality improvement. We estimated the use of smoking cessation in new smoking-related GU cancer visits based on billing claims.

METHODS

From MarketScan data, over 34 million enrollees aged 18 to 65 years, calendar years 2007 to 2011, were screened for billing codes for index UCB/UCUT or RCC and tobacco use disorder. Qualifying individuals were assessed for claims-based pharmacologic or counseling smoking cessation interventions in the 12 months following diagnosis using Current Procedural Terminology (CPT) codes and International Classification of Diseases Ninth Revision (ICD-9) codes. Multivariable logistic regression identified factors associated with smoking cessation intervention.

RESULTS

From over 111,453 incident cancers, 5,777 smokers with tobacco-related GU malignancy were identified by billing claims (40% UCB, 46% RCC, 4.2% UCUT, and 9.8% multiple cancers). Claims for intervention were rare (5.3%). Among intervention recipients, 240 (80%) had UCB and 92% had claims for either counseling or medications, only 8% had both. Most claims-based interventions (61%) were within 3 months after GU cancer diagnosis. On multivariable analysis UCB was associated increased odds of claims-based intervention (odds ratio [OR] = 6.27; 95% CI: 4.57-8.60) compared with UCUT and RCC. Other significant factors included more comorbidities (Charlson score = 1, OR = 1.50, 95% CI: 1.06-2.13; Charlson score≥2, OR = 1.89, 95% CI: 1.19-3.02 compared with Charlson score = 0) and diagnosis in the latter half of the study period (OR = 1.30, 95% CI: 1.02-1.67 compared with earlier years).

CONCLUSIONS

Although a new diagnosis of a smoking-related GU malignancy diagnosis offers greater opportunity for provider-driven smoking cessation, timely multimodal claims-based cessation interventions are underreported or underused.
