Ethnicity and Smoking Status are Associated with Awareness of Smoking Related Genitourinary Diseases

Effect of smoking on the recurrence and progression of non-muscle-invasive bladder cancer

BACKGROUND

It is well established that smoking is the most significant risk factor for bladder cancer, yet the impact of smoking on the recurrence and progression of non-muscle-invasive bladder cancer (NMIBC) remains a contentious issue.

OBJECTIVE

To review all relevant literature published to date, providing a comprehensive assessment of the effects of smoking on the recurrence and progression of NMIBC, thereby offering a basis for smoking cessation management in NMIBC patients.

METHODS

A search was conducted for all relevant literature published up to April 2024 in PubMed, Web of Science, and Embase databases. The existing literature results and deficiencies were analyzed, and the gaps in understanding between different studies were highlighted, with recommendations for future research.

RESULTS

A total of 24 studies were included in this work. Among them, 14 studies suggested that smoking promotes the recurrence and progression of NMIBC, while another 10 studies concluded that smoking has no effect on the recurrence and progression of NMIBC patients.

CONCLUSIONS

Our research indicates that smoking increases the risk of recurrence and progression in NMIBC patients, and quitting smoking can improve health-related quality of life. High-quality, large-sample prospective cohort studies (or randomized controlled studies) are still needed in the future.

Influence of substance use on male reproductive health and offspring outcomes

The prevalence of substance use globally is rising and is highest among men of reproductive age. In Africa, and South and Central America, cannabis use disorder is most prevalent and in Eastern and South-Eastern Europe, Central America, Canada and the USA, opioid use disorder predominates. Substance use might be contributing to the ongoing global decline in male fertility, and emerging evidence has linked paternal substance use with short-term and long-term adverse effects on offspring development and outcomes. This trend is concerning given that substance use is increasing, including during the COVID-19 pandemic. Preclinical studies have shown that male preconception substance use can influence offspring brain development and neurobehaviour through epigenetic mechanisms. Additionally, human studies investigating paternal health behaviours during the prenatal period suggest that paternal tobacco, opioid, cannabis and alcohol use is associated with reduced offspring mental health, in particular hyperactivity and attention-deficit hyperactivity disorder. The potential effects of paternal substance use are areas in which to focus public health efforts and health-care provider counselling of couples or individuals interested in conceiving.

Cigarette smoking and erectile dysfunction: an updated review with a focus on pathophysiology, e-cigarettes, and smoking cessation

Introduction

Cigarette smoking has major health implications and causes substantial damage to all organ systems. Approximately one-third of men are active smokers worldwide, and most men are unaware that cigarette smoking can contribute to erectile dysfunction (ED).

Objectives

This article aims to provide a comprehensive overview of research conducted on cigarette smoking and ED, with a particular focus on pathophysiology, electronic cigarettes (e-cigarettes), and smoking cessation.

Methods

A manual literature search was conducted on all research conducted on cigarette smoking and ED up to October 2022.

Results

Substantial evidence is now available showing that past and current cigarette smoking has dose-dependent associations with ED in studies controlling for age and important health comorbidities. Cigarette smoke contains nicotine, carbon monoxide, oxidant chemicals, and metals that can damage the endothelium and disrupt erectile processes. For current smokers, smoking abstinence can strengthen the endothelium and reverse diminished erectile function. The effect of e-cigarettes on endothelial damage and ED remains largely untested. E-cigarettes expose users to fine and ultrafine particles and toxins that can increase risk of cardiovascular injury, but these acute effects appear less potent than conventional cigarettes (long-term cardiovascular effects are still unknown). E-cigarettes are therefore likely to have less harmful effects on ED than conventional cigarettes.

Conclusions

Smoking cessation programs that focus on nicotine replacement therapy (transdermal patches, gum, or inhalers), behavioral counseling, social support, and education programs can be effective approaches to ED treatment in active smokers. Temporarily transferring from regular cigarettes to e-cigarettes—which transmit some of the same carcinogens as conventional cigarettes and are likely to have some long-term cardiovascular effects that disrupt erectile function—might also be useful for long-term smoking cessation and treatment of ED.

Smoking Behaviors and Prognosis in Patients With Non-Muscle-Invasive Bladder Cancer in the Be-Well Study

Importance

Tobacco smoking is an established risk factor associated with bladder cancer, yet its impact on bladder cancer prognosis is unclear.

Objective

To examine associations of use of tobacco (cigarettes, pipes, and cigars), e-cigarettes, and marijuana with risk of recurrence and progression of non-muscle-invasive bladder cancer (NMIBC) and to explore use of smoking cessation interventions.

Design, Setting, and Participants

The Be-Well Study is a prospective cohort study of patients with NMIBC diagnosed from 2015 to 2019 and followed-up for 26.4 months in the Kaiser Permanente Northern and Southern California integrated health care system. Eligibility criteria were age at least 21 years, first NMIBC diagnosis (stages Ta, Tis, or T1), alive, and not in hospice care. Exclusion criteria were previous diagnosis of bladder cancer or other cancer diagnoses within 1 year prior to or concurrent with NMIBC diagnosis. Data were analyzed from April 1 to October 4, 2022.

Exposures

Use of cigarettes, pipes, cigars, e-cigarettes, and marijuana was reported in the baseline interview. Use of smoking cessation interventions (counseling and medications) was derived from electronic health records.

Main Outcomes and Measures

Hazard ratios (HRs) and 95% CIs of recurrence and progression of bladder cancer were estimated by multivariable Cox proportional hazards regression.

Results

A total of 1472 patients (mean [SD] age at diagnosis, 70.2 [10.8%] years; 1129 [76.7%] male patients) with NMIBC were enrolled at a mean (SD) of 2.3 (1.3) months after diagnosis, including 874 patients (59.4%) who were former smokers and 111 patients (7.5%) who were current cigarette smokers; 67 patients (13.7%) smoked pipes and/or cigars only, 65 patients (4.4%) used e-cigarettes, 363 patients (24.7%) used marijuana. Longer cigarette smoking duration and more pack-years were associated with higher risk of recurrence in a dose-dependent manner, with the highest risks for patients who had smoked for 40 or more years (HR, 2.36; 95% CI, 1.43-3.91) or 40 or more pack-years (HR, 1.97; 95% CI, 1.32-2.95). There was no association of having ever smoked, being a former or current cigarette smoker, and years since quit smoking with recurrence risk. No associations with pipes, cigars, e-cigarettes, or marijuana were found. Of 102 patients offered a smoking cessation intervention, 57 (53.8%) received an interventions after diagnosis, with female patients more likely than male patients to engage in such interventions (23 of 30 female patients [76.7%] vs 34 of 76 male patients [44.7%]; P = .003).

Conclusions and Relevance

These findings suggest that longer duration and more pack-years of cigarette smoking were associated with higher risk of NMIBC recurrence. Cigarette smoking remains a critical exposure before and after diagnosis in survivors of NMIBC.

Changes in Cigarette Smoking Behavior in Cancer Survivors During Diagnosis and Treatment

INTRODUCTION

Continued cigarette smoking is a critical determinant of outcome in oncology patients, but how the separate events of cancer diagnosis, cancer treatment, and completion of treatment affect smoking behavior in cancer survivors is unknown. This study described such changes, hypothesizing that they would be more pronounced for smoking-related cancers.

METHODS

The Cancer Patient Tobacco Use Questionnaire (CTUQ) was sent to every cancer patient ≥ 18 y old scheduled for outpatient visits at the Mayo Clinic Cancer Center with a current or former history of tobacco use.

RESULTS

From September 2019 to September 2020, 33,831 patients received the CTUQ, and 20,818 (62%) responded. Of the 3007 current smokers analyzed, 34% quit at diagnosis; those with smoking-related cancers were more likely to quit (40% vs. 29%, respectively, p < .001). Among those who did not quit at diagnosis, 31% quit after starting cancer treatment, and those with smoking-related cancers were more likely to quit (35% and 28%, respectively, p = .002) Among those who had quit before the completion of treatment, 13% resumed smoking after treatment ended. In multivariable analysis, patients with smoking-related cancers were more likely to report 30-d point prevalence abstinence from pre-diagnosis to the completion of treatment (adjusted OR 1.98 [95% CI 1.65, 2.36], p < .001).

CONCLUSIONS

Both cancer diagnosis and treatment prompt smoking abstinence, with most maintaining abstinence after treatment is completed. Those with smoking-related cancers are more likely to quit. These results emphasize the need to provide access to tobacco treatment services that can further support cancer patients who smoke.

IMPLICATIONS

Approximately one-third of cancer patients who smoke quit smoking at the time of diagnosis, an additional one-third of patients who had not yet quit did so at the initiation of treatment, and most sustained this abstinence after treatment completion. Patients with smoking-related cancers are more likely to quit. Thus, there are multiple opportunities within the cancer care continuum to intervene and support quit attempts or continued abstinence.

Patterns and associations of smoking and electronic cigarette use among survivors of tobacco related and non-tobacco related cancers: A nationally representative cross-sectional analysis

BACKGROUND

Tobacco-use among cancer survivors leads to preventable morbidity, mortality, and increased healthcare costs. We sought to explore the prevalence of smoking and e-cigarette use among survivors of tobacco and non-tobacco related cancers.

METHODS

A cross-sectional analysis was conducted using the 2015-2018 National Health Interview Survey. Our primary outcome was the prevalence of current cigarette smoking or e-cigarette use among adults with self-reported history of tobacco related or non-tobacco related cancer. Logistic regression analysis was to assess the association of reported cancer type with cigarette smoking or e-cigarette use. Secondary outcomes included yearly trends and dual use.

RESULTS

A total of 12,984 respondents reported a history of cancer, representing a weighted estimate of 5,060,059 individuals with a history of tobacco-related malignancy and 17,583,788 with a history of a tobacco and non-tobacco related cancer, respectively. Survivors of tobacco-related cancers had a significantly higher prevalence of current cigarette use (18.2 % vs 9.7 %, P < 0.0001), e-cigarette use (2.7 % vs 1.6 %, P < 0.0001) and similar rates of dual use. The prevalence of cigarette smoking among all survivors increased as time increased from the year of diagnosis up to 2 years post-diagnosis (P = 0.047). Odds of reporting current cigarette smoking use was higher for survivors of tobacco-related cancers, adjusted for sociodemographic factors (OR1.69, 95 % CI 1.44-1.99).

CONCLUSIONS

Survivors of tobacco-related cancers have a higher prevalence of current cigarette smoking and e-cigarette use compared to survivors of non-tobacco related cancers. There was a sequential increase in the prevalence of cigarette use during each subsequent year from the time of a new cancer diagnosis, underscoring the need for long term tobacco cessation support among newly diagnosed adults with cancer.

Life expectancy in metastatic urothelial bladder cancer patients according to race/ethnicity

PURPOSE

to compare observed overall survival vs age-adjusted lifetable (LT) derived life expectancy (LE) in metastatic urothelial bladder cancer (MBCa) patients according to race/ethnicity.

METHODS

We identified Caucasian, African American, Hispanic/Latino and Asian metastatic urothelial bladder cancer patients from 2004 to 2011 within the Surveillance, Epidemiology and End Results database. Social Security Administration tables were used to compute 5 year LE. LT-derived LE was compared to observed overall survival OS. Additionally, we relied on Poisson regression plots to display cancer-specific mortality (CSM) relative to other-cause mortality (OCM) for each race/ethnicity.

RESULTS

Overall, 2286 MBCa patients were identified. Of those, 1800 (79%) were Caucasian vs 212 (9.3%) African American vs 189 (8.3%) Hispanic/Latino vs 85 (3.7%) Asians. The median age at diagnosis was 71 years for Asians vs 70 for Caucasians vs 67 for Hispanic/Latinos vs 67 for African Americans. African Americans showed the biggest difference between observed OS and LT-predicted LE at five years (- 83.8%), followed by Hispanic/Latinos (- 81%), Caucasians (- 77%) and Asian patients (- 69%). In Poisson regression plots, Hispanic/Latinos displayed the highest cancer-specific mortality rate (88%), while African/Americans showed the highest other cause mortality rate (12%). Conversely, Asian patients displayed the lowest CSM rate (83%) and second lowest OCM rate (7%).

CONCLUSIONS

African Americans showed the least favorable survival profile in MBCa, despite being youngest at diagnosis. Contrarily, Asians displayed the best survival profile in MBCa, despite being oldest at diagnosis.

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.

Racial differences in the distribution of bladder cancer metastases: a population-based analysis

INTRODUCTION

Bladder cancer is the second most common genitourinary malignancy in the United States. The incidence of bladder cancer rises with age, and it is two times more common in Caucasians than in African-Americans (23.1 vs. 12.6 cases/100,000 persons). We aimed to investigate the racial and age-related differences in the distribution of metastasis in a large, contemporary cohort of metastatic bladder cancer patients.

MATERIAL AND METHODS

Within the National Inpatient Sample database (2008-2015) we identified 5,767 patients with metastatic bladder cancer. Trend test, Chi-square test and multivariable logistic regression models were used to evaluate the relationship between ethnicity, age, and site of metastasis.

RESULTS

Of 5,767 patients with metastatic bladder cancer, 598 (10.4%) were African-American. Lung was the most common metastatic site in African-Americans (28.6%) vs. bone in Caucasians (21.7%). Overall, African-Americans showed higher rates of lung (+10.2%), liver (+7.5%) and bone (+5.2%) metastases, compared to Caucasians (all p <0.01). Brain metastases were rare in both ethnicities (3.3 vs. 2.4%; p = 0.2). Rates of exclusive bone, lung or liver metastases increased with age, but were higher in African-Americans, regardless of age strata. In the multivariable logistic regression models, African-American ethnicity independently predicted higher risk of lung (Odds ratio: 1.69), liver (odds ratio: 1.50) and bone (odds ratio: 1.27) metastases, relative to Caucasians. Moreover, a dose-response effect was found after combining the three main risk factors for developing bone metastases, namely African-American ethnicity, younger age and male gender.

CONCLUSIONS

Racial differences exist in the distribution of metastatic bladder cancer metastasis. Moreover, based on higher risk of bone metastases in African-American patients, bone imaging may be warranted in this patient population, especially in the presence of other risk factors for bone metastases, namely male gender or younger age.

Lifestyle in urology: Cancer

The opportunity to prevent, to improve their prognosis, or even to cure uro-oncological diseases by modifying the lifestyle habits is a very modern topical subject and represents a great and fascinating challenge for the future. A PubMed and Web of Science databases search has been performed to review the published knowledge on most important lifestyle habits, such as smoking, physical activity, nutrition, sexual activity, and personal hygiene, highlighting modifiable factors influencing development and progression of urological cancers. Cigarette smoking has been historically established as risk factors for urothelial cancer, and an association with risk of renal cell carcinoma and worse prognosis of prostate cancer has been sufficiently demonstrated. Poor genital hygiene is a recognized risk factor for penile cancer. Furthermore, a convincing evidence has been found on the association between physical activity and both risk and prognosis of bladder and prostate cancer. Obesity is strongly associated with increased risk of developing lethal prostate cancer. An unequivocal evidence of a direct relationship between most of the other lifestyle habits and development of the uro-oncological diseases has not been found.

Cigarette smoking promotes bladder cancer via increased platelet-activating factor

Cigarette smoking is the number one risk factor for bladder cancer development and epidemiological data suggest that nearly half of all bladder cancer patients have a history of smoking. In addition to stimulating the growth of a primary tumor, it has been shown that there is a correlation between smoking and tumor metastasis. Platelet activating factor (PAF) is expressed on the cell surface of the activated endothelium and, through binding with the PAF-receptor (PAF-R), facilitates transendothelial migration of cells in the circulation (McHowat et al. Biochemistry 40:14921-14931; 2001). In this study, we show that the exposure of bladder cancer cells to cigarette smoke extract (CSE) results in increased PAF accumulation and increased expression of the PAF-R. Furthermore, treatment with CSE increases adherence of bladder cancer cells to bladder endothelial cells and could be abrogated by pretreatment with ginkgolide B. Immunohistochemical analysis of tumor biopsy samples from bladder cancer patients who smoked revealed increased PAF and the PAF-R in tumor regions when compared to normal tissue. These data highlight a pathway in bladder cancer that is influenced by CSE which could facilitate primary tumor growth and increase metastatic potential. Targeting of the PAF-PAFR interaction could serve as a beneficial therapeutic target for managing further growth of a developing tumor.

Lifestyle and nutritional modifiable factors in the prevention and treatment of bladder cancer

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.

Knowledge of smoking as a risk factor for disease among urology clinic patients in Australia

INTRODUCTION

Smoking remains a common habit among the general population. Despite the well-established risks of smoking, relatively few studies have been undertaken to assess the understanding of these risks among the general population. We intended to assess the understanding of smoking as a risk factor for various conditions in a urology outpatient cohort to assess the level of knowledge as well as particular strengths and weaknesses they possess.

METHODS

A four-page questionnaire was distributed among urology outpatients over a 5 month period. The questionnaire captured information regarding the knowledge of smoking as a risk factor for various urological and non-urological conditions. Results were collated and stratified according to patient's cancer history as well as smoking status.

RESULTS

A total of 112 participants were included in our analytical sample. Our study demonstrated a deficiency in knowledge regarding smoking and urological conditions. When ranked by level of knowledge, four of the bottom five conditions were urological in nature. Furthermore, we found that patients with a personal cancer history demonstrated generally poorer knowledge of smoking as a risk factor compared to patients without a cancer history. Conversely, smokers themselves demonstrated a greater understanding of risks compared to non-smokers.

CONCLUSIONS

Our study suggests there is much work to be done in the education of patients on the risks of smoking from a urological point of view. We believe more initiative needs to be taken by the specialists treating such patients to achieve an improved level of knowledge.

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.

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.

Fast-track access to urologic care for patients with macroscopic haematuria is efficient and cost-effective: results from a prospective intervention study

Background:

The delay between onset of macroscopic haematuria and diagnosis of bladder cancer is often long.

Methods:

We evaluated timely diagnosis and health-care costs for patients with macroscopic haematuria given fast-track access to diagnostics. During a 15-month period, a telephone hotline for fast-track diagnostics was provided in nine Swedish municipalities for patients aged ⩾50 years with macroscopic haematuria. The control group comprised 101 patients diagnosed with bladder cancer in the same catchment area with macroscopic haematuria who underwent regular diagnostic process.

Results:

In all 275 patients who called ‘the Red Phone' hotline were investigated, and 47 of them (17%) were diagnosed with cancer and 36 of those had bladder cancer. Median time from patient-reported haematuria to diagnosis was 29 (interquartile range (IQR) 14−104) days and 50 (IQR 27−165) days in the intervention and the control group, respectively (P=0.03). The median health-care costs were lower in the intervention group (655 (IQR 655−655) EUR) than in the control group (767 (IQR 490−1096) EUR) (P=0.002).

Conclusions:

Direct access to urologic expertise and fast-track diagnostics is motivated for patients with macroscopic haematuria to reduce diagnostic intervals and lower health-care expenditures.

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

BACKGROUND

The objective of this study was to determine tobacco use knowledge and attribution of cause in patients with newly diagnosed bladder cancer.

METHODS

A stratified, random sample of bladder cancer survivors diagnosed between 2006 and 2009 was obtained from the California Cancer Registry. Respondents were surveyed about tobacco use, risk factors, and sources of information on the causes of bladder cancer. Contingency tables and logistic regression analyses were used to evaluate tobacco use knowledge and beliefs.

RESULTS

Of 1198 eligible participants, 790 (66%) completed the survey. Sixty-eight percent of the cohort had a history of tobacco use, and 19% were active smokers at diagnosis. Tobacco use was the most cited risk factor for bladder cancer, with active smokers more knowledgeable than former smokers or never smokers (90% vs 64% vs 61%, respectively; P<.001). Urologists were the predominant source of information and were cited most often by active smokers (82%). In multivariate analyses, active smokers had 6.37 times greater odds (95% confidence interval, 3.35-12.09) than never smokers of endorsing tobacco use as a risk factor for bladder cancer, and smokers who named the urologist as their information source had 2.80 times greater odds (95% confidence interval, 1.77-4.43) of believing tobacco use caused their cancer.

CONCLUSIONS

Patients' smoking status and primary source of information were associated with knowledge of the harms of tobacco use and, in smokers, acknowledgment that tobacco use increased the risk of their own disease. Urologists play a critical role in ensuring patients' knowledge of the connection between smoking and bladder cancer, particularly for active smokers who may be motivated to quit.

Bladder cancer: a portal into men's health

Bladder cancer is the fourth most common cancer among men in the United States, with a 3-fold higher incidence than women. Globally, tobacco smoking remains significantly more common in men, contributing to half of all cases of bladder cancer. To prevent bladder cancer, urologists should promote smoking cessation to patients presenting at earlier ages with concerns such as sexual dysfunction, infertility, pelvic pain, or vasectomy. Bladder cancer also provides an entry point for men into the healthcare system, at which time, urologists can discuss and coordinate attention to other male health issues such as cardiovascular illness, depression, or addiction. By assuming the role of men's health physicians, urologists can have a significant benefit on men's urologic and overall health by targeting risk factors and behaviors.

The future of bladder cancer care in the USA

Bladder cancer is the fifth most common malignancy in the USA and the most expensive to treat on a per-patient basis. Despite its prevalence, morbidity, mortality and associated cost of management, bladder cancer remains grossly under-recognized as a public health concern and underfunded scientifically. Although 5-year survival rates for patients with prostate or kidney cancer have improved tremendously in the past 30 years, progress in bladder cancer has stalled. A renewed interest from the clinical and research communities, as well as a young and eager advocacy network, are raising the profile of bladder cancer. As awareness and funding of bladder cancer increase, improved diagnostics, therapeutics and health services for patients with the disease will develop accordingly.

Brief smoking cessation intervention: a prospective trial in the urology setting

PURPOSE

Urologists have an important role in the treatment of tobacco related diseases, such as kidney and bladder cancer. Despite this role, urologists receive little training in promoting tobacco cessation. We prospectively evaluated a brief smoking cessation intervention offered by a urologist at an outpatient clinic.

MATERIALS AND METHODS

Between 2009 and 2011 adult smokers from a single institution urology clinic were enrolled in a prospective, brief intervention trial or in usual care as controls. All patients were assessed by the validated Fagerström test for nicotine dependence and the readiness to quit questionnaire. Trial patients received a 5-minute brief smoking cessation intervention. The primary outcome was abstinence at 1 year and the secondary outcome was the number of attempts to quit. Multivariate logistic regression was used to identify factors associated with the quit rate and quit attempts.

RESULTS

A total of 179 patients were enrolled in the study, including 100 in the brief smoking cessation intervention, 41 in the brief smoking cessation intervention plus nicotine replacement therapy and 38 usual care controls. Of the participants 81.0% were 40 years old or older with a mean ± SD 11.26 ± 7.23 pack-year smoking history. Mean readiness to quit and tobacco dependence scores were similar in the 2 arms (p = 0.25 and 0.92, respectively). The 1-year quit rate in the brief smoking cessation intervention group was 12.1% vs 2.6% in the usual care group (OR 4.44, p = 0.163) Adding nicotine replacement therapy increased the quit rate to 19.5% (vs usual care OR 9.91, p = 0.039). Patients who received the brief smoking cessation intervention were significantly more likely to attempt to quit (OR 2.31, p = 0.038). Increased readiness scores were associated with an increased quit rate and increased quit attempts.

CONCLUSIONS

Urologists can successfully implement a brief smoking cessation intervention program. Our study highlights the role of the urologist in providing smoking cessation assistance and the significant impact of brief, simple advice about quitting smoking on the smoker quit rate.
