Correlates of tobacco use among smokers and recent quitters diagnosed with cancer

Tobacco Cessation Interventions in Non-Respiratory Cancers: A Systematic Review With Meta-analysis of Randomized Controlled Trials

BACKGROUND

Considering the high rates of persistent tobacco use, effective cessation interventions are needed for cancer patients and caregivers. Despite the need, there is a significant lack of research on tobacco cessation, especially for non-respiratory cancers (breast, prostate, colorectal, cervical, and bladder cancer).

PURPOSE

The objective was to evaluate tobacco use and tobacco cessation interventions among patients and caregivers for non-respiratory cancers.

METHODS

Randomized controlled trials assessing tobacco cessation interventions were identified. Five electronic databases were searched in accordance with the Preferred Reporting Items for Systematic reviews and Meta-analyses guidelines through July 2023. Studies exclusive to lung, oral, thoracic, and head and neck cancers were excluded. Effect sizes were estimated; risk of bias was assessed.

RESULTS

Of 3,304 studies, 17 were included. Interventions included behavioral (n = 6), pharmacotherapy (n = 2), and a combination (n = 9) treatment. Eight studies included a health behavior model; mean behavioral change techniques were 5.57. Pooled magnitude of the odds of cessation was positive and significant (odds ratio = 1.24, 95% confidence interval [Lower Limit 1.02, Upper Limit 1.51]) relative to usual care/placebo. Cumulative meta-analysis examined the accumulation of results over-time and demonstrated that studies have been significant since 2020. Two studies included caregivers' who were involved in the provision of social support.

CONCLUSIONS

Current interventions have the potential to reduce tobacco use in non-respiratory cancers. Results may be beneficial for promoting tobacco cessation among non-respiratory cancers. There is a considerable lack of dyadic interventions for cancer survivors and caregivers; researchers are encouraged to explore dyadic approaches.

Brief intervention to enhance cessation of smokeless tobacco use in newly diagnosed patients with head and neck cancers: A randomized controlled trial in patient-relative dyads

Introduction

Tobacco use is a major causative factor for head and neck cancers (HNC). Continued use of tobacco even after cancer diagnosis is common and is associated with all-cause and cancer-specific mortality, cancer recurrence and poor treatment response. Evidence suggests that behavioral interventions, help achieve greater smoking cessation rates in HNC patients. However, intervention studies focussed on HNC patients using smokeless tobacco, which is more common than smoking in India, are sparse.

Materials and Methods

We conducted a parallel arm randomized controlled trial (RCT) on dyads of patients with recently diagnosed HNC and a close relative. The experimental arm received a brief tobacco cessation intervention (BTCI) and the control arm received treatment as usual (TAU); 27 and 25 dyads in each arm completed the trial.

Results

Overall for the dyads using SLT, the relative risk of continuing to use SLT was 3.23 times higher (odds ratio = 7.01) if BTCI was not undertaken at one-month follow-up and 4.43 times higher (odds ratio = 8.65) at 3-months follow-up. For patients only, the relative risk of continuing to use SLT at one-month and 3-months follow-ups was 4.99 and 12.04 times higher, respectively, if BTCI was not undertaken. For relatives only, the corresponding relative risk values were 2.14 and 2.2.

Conclusion

We conclude that BTCI delivered to patient-relative dyads, compared to TAU, is effective in enhancing the discontinuation rates of the use of SLT in newly diagnosed patients with HNC. This form of intervention is significantly effective for discontinuing SLT use in the relatives too.

Unlocking infodemics and mysteries in COVID-19 vaccine hesitancy: Nexus of conspiracy beliefs, digital informational support, psychological Well-being, and religious fatalism

Guarding against an anti-science camouflage within infodemics is paramount for sustaining the global vaccination drive. Vaccine hesitancy remains a growing concern and a significant threat to public health, especially in developing countries. Infodemics, conspiracy beliefs and religious fatalism primarily fuel vaccine hesitancy. In addition, anti-vaccine disinformation, lack of understanding, and erroneous religious beliefs also trigger vaccine hesitancy. Global behavioral strategies such as wearing face masks and long-term preventive measures (i.e., COVID-19 vaccination) have effectively limited the virus's spread. Despite the alarming rate of global deaths (i.e., over 99% being unvaccinated), a large proportion of the global population remains reluctant to vaccinate. New evidence validates the usefulness of technology-driven communication strategies (i.e., digital interventions) to address the complex socio-psychological influence of the pandemic. Hence, the present research explored the digital information processing model to assess the interface between informational support (through digital interventions) and antecedents of vaccine hesitancy. This research involved two separate studies: a focus group to operationalize the construct of infodemics, which remained ambiguous in previous literature (Study 1), followed by a cross-sectional survey (Study 2) to examine the conceptual model. Data were collected from 1906 respondents through a standard questionnaire administered online. The focus group's findings revealed a multi-dimensional nature of infodemics that was also validated in Study 2. The cross-sectional survey results substantiated infodemics, religious fatalism and conspiracy beliefs as significant predictors of vaccine hesitancy. Similarly, conspiracy beliefs negatively influence an individual's psychological well-being. Furthermore, information support (through digital intervention) affected infodemics and religious fatalism, whereas it inversely influenced the strength of their relationships with vaccine hesitancy. Information support (through digital intervention) also moderated the relationship between conspiracy beliefs and psychological well-being.

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.

The Impact of Treatment for Smoking on Breast Cancer Patients' Survival

BACKGROUND

Smoking negatively affects overall survival after successful breast cancer (BC) treatment. We hypothesized that smoking cessation would improve survival outcomes of BC patients who were smokers at the time of diagnosis.

METHODS

This was a retrospective analysis of self-identified smokers with BC treated at The University of Texas MD Anderson Cancer Center. Patient demographics, date of diagnosis, tumor stage, tobacco treatment program (TP) participation, and time to death were extracted from our departmental databases and institutional electronic health records. We examined associations between tobacco abstinence status and survival using survival models, with and without interactions, adjusted for personal characteristics and biomarkers of disease.

RESULTS

Among all 31,069 BC patients treated at MD Anderson between 2006 and 2017, we identified 2126 smokers (6.8%). From those 2126 self-identified smokers, 665 participated in the TP, reporting a conservative estimate of 31% abstinence (intent-to-treat) 9 months into the program. Patients without reported follow-up abstinence status (including TP and non-TP participants) were handled in the analyses as smokers. Survival analysis controlled for multiple factors, including disease characteristics and participation in the TP, indicated that abstainers were more likely to be alive with no evidence of disease compared to non-abstainers (HR, 0.593; 95% CI, 0.386-0.911; p = 0.017).

CONCLUSION

Our results suggest that quitting smoking is associated with improved survival among BC patients who were smokers at time of diagnosis across all tumor stages. Comprehensive approaches for smoking cessation in patients diagnosed with BC may prolong survival when started as early as the time of diagnosis.

Qualitative study of Stroke Survivors' Perceptions of Secondary Prevention

AIMS

To understand how survivors of stroke perceive secondary prevention and explore their perceived barriers and facilitators using the Theoretical Domains Framework.

DESIGN

A qualitative descriptive study.

METHODS

Nineteen survivors of stroke from three hospitals were recruited and interviewed from April 2019 to April 2020. The data were analysed deductively and inductively by content analysis strategies.

RESULTS

Three main themes of perception of secondary prevention were identified, these being active treatment-seeking, attention to taking medications and negative attitude towards lifestyle changes. Using deductive analysis, eight domains of the Theoretical Domains Framework were reported to be relevant in the secondary prevention behaviour of survivors of stroke that mapped to five 'barrier' domains (i.e. knowledge, physical skills, beliefs about capability, beliefs about consequences and optimism) as well as six 'facilitator' domains (i.e. knowledge, interpersonal skills, beliefs about capability, intention, emotion and social influences). Using inductive analysis we identified two additional important factors not falling in the domains of the Theoretical Domains Framework. These comprised female spouses' support and patients' economic autonomy, both of which could be classified as a facilitator or barrier.

CONCLUSION

Survivors of stroke perceive seeking treatment and using preventive medication as more important than modifying lifestyle behaviours. Knowledge and insight into the barriers and facilitators of secondary prevention in this specific context provides a theoretical and practical basis for the design of future secondary prevention interventions.

IMPACT

Stroke survivors' perceptions of secondary prevention, barriers and facilitators were explored in the context of a developing country. These findings highlight the need to better communicate the importance of improving lifestyle modification and medication adherence, and provide evidence for designing relevant interventions for stroke management in the community.

Time to put it out - nurse-facilitated tobacco treatment in a comprehensive cancer center

Few cancer patients receive guideline-concordant care for treatment of tobacco dependence. The purpose of this pilot trial was to obtain preliminary estimates of effectiveness of an evidence-based practice intervention on the delivery of tobacco treatment and cessation outcomes in cancer patients. We conducted a pragmatic implementation trial with a before-after design in 119 current or recently quit adult smokers with cancer who met with a clinician at a single National Cancer Institute designated comprehensive cancer center (CCC) (n = 61 pre-implementation, n = 58 post-implementation). We used a multi-component strategy based on the Chronic Care Model to implement National Comprehensive Cancer Network (NCCN) guidelines for smoking cessation. Smoking cessation counseling during the index visit was assessed by exit interview and patients were interviewed by phone to assess cessation outcomes at 3-month follow-up. Performance of cessation counseling and 7-day point prevalence abstinence (PPA) were compared across the pre- and post-implementation periods using log-logistic regression, accounting for clustering by nursing staff. More patients had received assistance in quitting at the index visit during the post-implementation period compared to the pre-implementation period (30 vs. 10%, p < .01). At 3-month follow-up, 38 and 14% of participants had discussed smoking cessation medication with a CCC healthcare professional and 57 and 27% of participants had used pharmacotherapy, respectively (p < .01 for both comparisons). Seven-day PPA at 3-month follow-up was similar in both periods, however (14 vs. 12%, respectively). A multi-component tobacco treatment intervention increased the proportion of smokers who received assistance in quitting smoking during usual cancer care but did not improve cessation outcomes.

E-cigarette and cigarette use among cancer survivors versus general population: a case-control study in Korea

PURPOSE

Although successful smoking cessation after cancer diagnosis is important, research on e-cigarette use and smoking behavior among cancer survivors (CS) is limited. This study compared cigarette and e-cigarette use among CS and non-cancer populations in Korea.

METHODS

This study analyzed the 2013-2018 National Health and Nutrition Survey data to investigate e-cigarette use and smoking behavior among Korean CS. The data were categorized into 1260 CS and 5040 non-cancer populations using the propensity score matching method. A multiple logistic regression was conducted among CS who previously used cigarettes or e-cigarettes to evaluate factors influencing successful cessation.

RESULTS

Regarding conventional smoking, the proportion of ex-smokers was higher (25.2% versus 19.9%) than current smokers (6.7% versus 10.6%) in the CS group than in the propensity matched non-cancer population (PMNCP) (p < 0.001). However, ever use of e-cigarettes did not differ between them (2.4% versus 2.7%, p = 0.529). Successful cessation, defined as not using either cigarettes or e-cigarettes, correlated with problem drinking (OR 0.442, 95% CI 0.207-0.940), depression (OR 0.276, 95% CI 0.087-0.872), and cancer sites. CS of stomach, liver, colorectal, and lung cancer maintained higher successful smoking cessation rates than PMNCP.

CONCLUSIONS

Korean CS had a higher cessation rate than PMNCP regarding conventional smoking; however, there was no difference in e-cigarette use.

IMPLICATIONS FOR CANCER SURVIVORS

In Korea, some CS continue to use e-cigarettes, and physicians should focus on helping them quit. Individualized and timely interventions should be provided for both cigarette and e-cigarette users, considering factors influencing successful cessation.

Prevalence and determinants of quitting smoking after cancer diagnosis: a prospective cohort study

OBJECTIVE

To describe smoking behaviours of patients with incident cancer attending an Italian cancer centre and to examine changes in their smoking habits within 12 months from cancer diagnosis, evaluating determinants of smoking cessation.

METHODS

A hospital-based prospective cohort included patients hospitalized in an Italian cancer centre (2016-2018). Patients were mostly female (74%) and included a limited proportion of aerodigestive cancers (7%). Face-to-face interviews were performed during hospital stay to gather information on patient characteristics and smoking history. Changes in smoking habits were assessed through telephone interviews at 3, at 6, and at 12 months after cancer diagnosis.

RESULTS

Among 1011 enrolled patients, 222 (22%) were current smokers at cancer diagnosis. Smoking prevalence was high in male patients (30%), in patients <50 years old (28%), in those with aerodigestive cancers (50%), and in those diagnosed at advanced stages (26%). Among current smokers at cancer diagnosis, 38% quit smoking after 12 months, 26% reduced intensity, and 36% did not modify smoking habits. Smoking cessation was associated with chemotherapy and, although not statistically significant, with female sex, older age, and advanced cancer stage. Patients with gastrointestinal, breast, or genitourinary cancer and those treated with surgery were less likely to quit smoking.

CONCLUSIONS

Our results highlighted that 62% of smoking patients with cancer did not quit the habit. Smoking cessation programs targeted to patients with cancer need intensification, particularly for those who may underestimate smoking effects after diagnosis.

Smoking-Related Health Beliefs in a Sample of Psychiatric Patients: Factors Associated with the Health Beliefs and Validation of the Health Belief Questionnaire

This study examined the (a) health beliefs and emotions (perception of risk, benefits, severity, and worry) about smoking among current and former smokers, (b) their awareness of health warnings, (c) factors associated with smoking-related health beliefs, and (d) the factor structure of the health belief questionnaire. Participants (n = 184) were recruited from a tertiary psychiatric care hospital. Current smokers showed a significantly higher risk perception and lower perceived benefits compared to former smokers. Younger age (<40 years), nicotine dependence (ND), a history of smoking-related diseases (SRD), and intention to quit were significantly associated with a higher risk perception in current smokers. Younger age, a history of SRDs, and motivation to quit were positively associated with health beliefs, while the latter two were associated with worry. Motivation and younger age were associated with a better perception of benefits and severity. Information on the cigarette packets was the major source of awareness for the sample, and 69% reported that existing campaigns were not effective in discouraging their smoking. Personalized risk communication and educational initiatives must focus on improving the knowledge of risk, benefits, and increase motivation to promote health cognition and thus smoking cessation.

The relationship between cancer fatalism and education

PURPOSE

Fatalism is defined by feelings of pessimism, hopelessness, and powerlessness regarding cancer outcomes. Early researchers reported associations between race and cancer fatalism. Yet current evidence suggests that social determinants of health are better predictors of cancer fatalism than race. Therefore, the aim of this study was to examine the association between age, race, education, and cancer fatalism.

METHODS

Three hundred ninety (n = 390) women who attended a screening mammogram at the Joanne Knight Breast Health Center at Siteman Cancer Center at Washington University School of Medicine (St. Louis, MO) completed the Powe Fatalism Inventory (PFI), a 15-item self-report instrument used to operationalize cancer fatalism. We used Pearson's correlation, independent samples t-tests, one-way ANOVA with post hoc tests, and linear regression to analyze the relationships between PFI total scores and age, race, and education.

RESULTS

There were no differences between the mean PFI scores for Non-Hispanic Whites (1.89, SD 0.55) and African Americans (2.02, SD 0.76, p = 0.092, 95% CI 0.27 to 0.02). We found significant differences between the mean PFI scores across levels of education. Women who attained a high school degree or less (n = 72) reported higher PFI scores (2.24, SD 0.77) than women who attended some college or post-high school vocational training (n = 111; 1.95, SD 0.61) and women with a college or postgraduate degree (n = 206; 1.83, SD 0.57). When PFI score was regressed onto age, race, and education, only education significantly explained fatalism (B = -0.19, p < 0.001).

CONCLUSIONS

In this study, cancer fatalism did not differ between Non-Hispanic White and African American women attending a screening mammogram. However, lower educational levels were associated with higher cancer fatalism. The previously observed associations between race and cancer fatalism may be explained by racial disparities in social determinants of health, such as education. Importantly, study findings indicate that the people with the greatest need for cancer fatalism interventions are those with lower educational levels.

Predictive Risk Factors for Continued Smoking after the Diagnosis of a Genitourinary Malignancy

OBJECTIVE

To determine risk factors for continued smoking following a diagnosis of a genitourinary (GU) malignancy. Smoking is a well established risk factor in the development of cancers involving the GU tract. Unfortunately, a large percentage of patients continue to smoke or relapse after cancer diagnosis; by doing so, there is an increased risk of recurrence, poor survival rates, treatment complications, secondary primary cancers, and other chronic smoking related illnesses.

MATERIALS AND METHODS

Two hundred and five patients who presented to a Urologic Oncology clinic at a single tertiary treatment center were given smoking cessation counseling and pharmacotherapy, as well as a questionnaire which was used to identify smoking status, demographics, and behavioral/psychosocial characteristics. Patients were followed for a minimum of 1 year with a median length of follow up for 13 months.

RESULTS

91% of patients enrolled in the study continued smoking at survey completion. After accounting for age, ethnicity, education and cigarettes consumed/day, 5 variables were independently associated with an increased risk of continued smoking: smoking 20 or more cigarettes per day, less than 2 prior quit attempts, anxiety and/or depression, fear of cancer recurrence, and home secondhand smoke exposure.

CONCLUSION

The role of the urologist is imperative for encouraging smoking cessation. While every patient should receive adequate counseling regarding smoking at the time of a GU malignancy diagnosis, identifying patients with the risk factors noted in this study and augmenting smoking cessation efforts may result in stronger efforts to quit and prevention of long-term complications.

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.

Comparison of prevalence and associated factors of depressive disorder between patients with head and neck cancer and those with lung cancer at a tertiary hospital in Taiwan: a cross-sectional study

OBJECTIVE

Depression is a common comorbidity in cancer patients. This study aimed to compare the prevalence and associated factors of depressive disorder between patients with head and neck cancer (HNC) and those with lung cancer (LC).

DESIGN

This study used a cross-sectional design with consecutive sampling.

SETTING

A medical centre (Kaohsiung Chang Gung Memorial Hospital, Taiwan).

PARTICIPANTS

Patients for the study were recruited from the HNC and LC outpatient clinic and inpatient ward from March 2016 to February 2018. Patients with HNC and LC were enrolled and assessed using the Mini International Neuropsychiatric Interview (MINI).

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary outcome was psychiatric diagnoses assessed using the MINI. The secondary outcomes were psychological well-being assessed using the Beck Anxiety Inventory, Taiwanese Depression Questionnaire, Brief Fatigue Inventory, Numeric Pain Rating Scale and the List of Threatening Experiences Questionnaire.

RESULTS

In total, 113 HNC patients and 104 LC patients were recruited for the study. The most common psychiatric comorbidity of HNC patients was alcohol use disorder (49.6%), followed by adjustment disorder (20.4%) and depressive disorder (11.5%). The most common psychiatric comorbidity of LC patients was depressive disorder (25.0%), followed by adjustment disorder (17.3%), alcohol use disorder (3.8%) and insomnia disorder (3.8%). Among HNC patients, a self-harm history was positively associated with depression (OR=11.91; 95% CI, 1.47 to 96.83), and a higher educational level was negatively associated with depression (OR=0.77; 95% CI, 0.66 to 0.91). Among LC patients, severity of stressor (OR=2.78; 95% CI, 1.50 to 5.15) and severity of anxiety (OR=1.18; 95% CI, 1.04 to 1.34) were two significant factors associated with depression.

CONCLUSION

We reported the prevalence and associated factors of depression between patients with HNC and those with LC. Clinicians should be aware of this comorbidity and the associated risk factors, and conduct intervention programmes to prevent these cancer patients from developing depression.

An Implementation Trial to Improve Tobacco Treatment for Cancer Patients: Patient Preferences, Treatment Acceptability and Effectiveness

Continued smoking after a cancer diagnosis increases mortality, risk of recurrence, and negatively impacts treatment effectiveness. However, utilization of tobacco use cessation treatment among cancer patients remains low. We conducted a clinical trial assessing patient preferences, treatment acceptability, and preliminary effectiveness (7-day point prevalence at 12 weeks) of three tobacco treatment options among cancer patients at an academic health center. Implementation strategies included electronic referral and offering the choice of three treatment options: referral to external services, including the quitline (PhoneQuit) and in-person group counseling (GroupQuit), or an internal service consisting of 6-week cognitive behavioral therapy delivered via smartphone video conferencing by a tobacco treatment specialist (SmartQuit). Of 545 eligible patients, 90 (16.5%) agreed to enroll. Of the enrolled patients, 39 (43.3%) chose PhoneQuit, 37 (41.1%) SmartQuit, and 14 (15.6%) GroupQuit. Of patients reached for 12-week follow-up (n = 35), 19 (54.3%) reported receiving tobacco treatment. Of all patients referred, 3 (7.7%) PhoneQuit, 2 (5.4%) SmartQuit, and 2 (14.3%) GroupQuit patients reported 7-day point prevalence abstinence from smoking at 12 weeks. Participants rated the SmartQuit intervention highly in terms of treatment acceptability. Results indicate that more intensive interventions may be needed for this population, and opportunities remain for improving reach and utilization.

Smoking Status Among Patients With Newly Diagnosed Lung Cancer in Taiwan

Background

Continued smoking after receiving a diagnosis of cancer seriously affects disease prognosis and survival. The prevalence and risk factors of continued smoking among patients with newly diagnosed lung cancer are unknown in Taiwan.

Purpose

The aims of this study were to assess the smoking status of patients with newly diagnosed lung cancer and to identify the characteristics that are associated with different smoking statuses.

Methods

Baseline data of a longitudinal study on smoking behaviors after lung cancer diagnosis were analyzed in this study. Patients were consecutively recruited from three medical centers in northern Taiwan. A structured questionnaire and medical chart reviews were used to collect data. Multinomial logistic regression analysis was used to examine the factors associated with continuing to smoke after being diagnosed with lung cancer.

Results

Among the 406 patients with newly diagnosed lung cancer who were recruited, 47.0% were never-smokers and 53.0% were ever-smokers. Among the second group, 38% were former smokers, 18% were recent quitters, and 44% were current smokers. Compared with former smokers, current smokers were more likely to be younger (OR = 1.05), to not exercise regularly (OR = 2.74), to currently live with smokers (OR = 2.48), and to have lower self-efficacy for refusing to smoke (OR = 0.95). Compared with recent quitters, current smokers were more likely to have lower self-efficacy for refusing to smoke.

Conclusions/Implications for Practice

A significant proportion of ever-smoker lung cancer patients in Taiwan will continue to smoke after receiving their diagnosis. Variables known to modify the risk factors associated with continued smoking such as regular exercise and better refusal self-efficacy should be considered and incorporated into future smoking cessation programs for patients with lung cancer.

Brief Intervention for Tobacco when Diagnosed with Oral Cancer (BITDOC): Study protocol of a randomized clinical trial studying efficacy of brief tobacco cessation intervention, Chhattisgarh, India

INTRODUCTION

Tobacco use is a major causative factor for cancer. Cessation programs along with diagnosis of cancer as a motivating factor may improve quitting rates in patients. This is a protocol of a study that aims to assess the efficacy of brief tobacco cessation intervention (compared to treatment as usual, TAU) on pattern and attitudes towards tobacco chewing in newly diagnosed head and neck cancer patients and their relatives.

METHODS

The proposed study will be conducted in two phases. Phase 1 will include 105 dyads of patients and relatives and shall assess patterns (amount, frequency, duration of use and dependence etc.) and knowledge and attitudes (quitting, continued use, health-behavioural modifications, long-term effects on treatment etc.) towards tobacco chewing in newly diagnosed head and neck cancer patients using smokeless tobacco and their relatives. Sample will be recruited from outpatients attending the ear, nose, throat and head and neck surgery department of a tertiary health care institute. Phase 2 will be a randomized trial that will compare the efficacy of the ‘Brief Intervention for Tobacco when Diagnosed with Oral Cancer’ (BITDOC) and TAU, and will include 27 dyads in each of the two groups. Intervention will be delivered in three sessions, based on the principles of motivational interviewing and the 3As model.

CONCLUSIONS

This study will help in the evaluation of the attitude towards smokeless tobacco (SLT) in a population that has faced the adverse consequences from its use and changes brought by a diagnosis of HNC. It will also help in developing a cost-effective model for promotion of smoking cessation.

Patterns of Tobacco Cessation Attempts and Symptoms Experienced Among Smokers With Head and Neck Squamous Cell Carcinoma

Importance

Among smokers with head and neck squamous cell carcinoma (HNSCC), there is ample evidence regarding the benefits of smoking cessation prior to treatment. Prior data indicates that increased attempts at cessation result in higher likelihood of cessation after diagnosis but the prediagnostic patterns of smoking cessation attempts among those smokers developing HNSCC has not been characterized. Data of this kind may direct cessation efforts toward increased efficacy.

Objective

To determine the frequency and character of tobacco cessation attempts and symptoms experienced prior to development of HNSCC, as well as to determine the correlation of these symptoms with number of cessation attempts and maximum quit days.

Design, Setting, and Participants

Cross-sectional study including 123 active smokers with HNSCC recruited from a tertiary medical center at an academic institution from February 2014 to May 2017.

Exposures

All included patients were active cigarette smokers prior to developing HNSCC.

Main Outcomes and Measures

Patients provided data indicating intensity of smoking, duration, number of cessation attempts, maximum number of days during which they successfully ceased smoking, and symptoms during cessation attempts. Principal component analysis was used to identify clustering of symptoms.

Results

In total, 123 patients were identified (97 men, 23 women, and 3 unspecified) from February 2014 to May 2017 as active smokers (mean [SD] age, 59.4 [9.0] years; median [interquartile range] age, 58.5 [54.8-66.0] years); patients had oral (n = 39 [32%]), oropharyngeal (n = 44 [36%]), laryngeal (n = 32 [26%]) or hypopharyngeal (n = 7 [6%]) tumors. Overall, 108 patients (88%) had made at least 1 prior attempt at cessation, and the mean number of lifetime cessation attempts was 6.6. Symptoms of cravings, restlessness, irritability, and anxiety were reported most frequently. Symptoms were clustered into 2 component groups: component group 1 (C1; increased appetite, cravings, depression) and component group 2 (C2; restlessness, irritability, insomnia, anxiety, and difficulty concentrating). Component group 2 correlated with quit attempts (Spearman correlation, 0.268 [95% CI, 0.07 to 0.45]), and C1 and C2 were not correlated with maximum quit days. Cessation attempts and maximum quit days positively correlated with each other.

Conclusions and Relevance

Our analysis shows that symptoms during cessation attempts tend to cluster and that most patients made 1 or more cessation attempts. Many patients successfully ceased before restarting. Our data suggest that patients experiencing C2 symptoms make more quit attempts; C1 symptoms may be more difficult to overcome because they are associated with fewer quit attempts. Future work will address whether amelioration of these symptoms may help smoking cessation among smokers with HNSCC.

Prevalence and analysis of tobacco use disorder in patients diagnosed with lung cancer

INTRODUCTION

Tobacco use disorder (TUD), previously known as nicotine dependence, was associated with increased risk of lung cancer. However, little is known about the prevalence of TUD and symptom manifestation in smokers with lung cancer.

OBJECTIVES

The aim of the present study was to investigate the prevalence of TUD using DSM-5 diagnostic criteria in patients diagnosed with lung cancer and analyze their tobacco use characteristics.

METHODS

A total of 200 histologically confirmed lung cancer patients who used tobacco within the prior 12-month period at the time of diagnosis were recruited for this study. Participants were assessed using interviewer-administered questionnaires to determine TUD symptoms and smoking-related behaviors, and self-administered Fagerstrom Test for Nicotine Dependence (FTND) was also administered.

RESULTS

The prevalence of DSM-5 TUD was 92.0% (n = 184). Of a total of 200 subjects, 23 (11.5%), 35 (17.5%), and 126 (63.0%) were classified into mild, moderate, and severe TUD categories, respectively. A total of 19 (81.3%) moderate TUD and 98 (77.8%) severe TUD patients had attempted smoking cessation. Of these subjects, 21 (21.4%) severe TUD and 12 (63.2%) moderate TUD patients tried more than three times. The number of satisfied criteria under DSM-5 TUD was positively correlated with FTND score, cumulative lifetime smoking amount, and daily smoking levels.

CONCLUSIONS

Smokers diagnosed with lung cancer showed a high prevalence of DSM-5 TUD. Their heavy and consistent tobacco use suggests reduced motivation to abstain from smoking.

Morbidity and associated factors of depressive disorder in patients with lung cancer

Objective

The aim of this study was to assess morbidity and associated factors in patients with lung cancer (LC).

Methods

This study used a cross-sectional design with consecutive sampling. Study subjects were recruited from the LC outpatient clinic and inpatient ward in a medical center from March 2016 to February 2018. Patients with LC were enrolled and assessed using the Mini International Neuropsychiatric Interview, Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, Brief Fatigue Inventory, Numeric Pain Rating Scale, and the List of Threatening Experiences Questionnaire.

Results

One hundred and four patients were included in the study. The most prevalent psychiatric disorder was depressive disorder (25.0%), followed by adjustment disorder (17.3%), alcohol use disorder (3.8%), and insomnia disorder (3.8%). Fifty percent of patients had a psychiatric diagnosis. Using logistic regression analysis, it was found that severity of fatigue (OR=1.77; 95% CI, 1.03–3.03; p<0.05), severity of stressor (OR=14.14; 95% CI, 2.49–80.20; p<0.05), and severity of anxiety (OR=3.75; 95% CI, 1.87–7.54; p<0.001) were three significant associated factors. Patient health problems, death of a close family member or friend, and major financial crisis were the three most common stressors among our cancer patients.

Conclusion

Use of a standardized structured interview for early diagnosis and treatment of cancer patients with depressive disorder is crucial and might increase their quality of life.

The effect of second hand smoke in patients with squamous cell carcinoma of the head and neck

Background

Active tobacco smoking is a well-known risk factor for head and neck malignancy, and strong evidence has associated tobacco as the main carcinogenic factor in squamous cell cancers of this region. Evidence supporting a carcinogenic effect of second-hand smoke (SHS) on head and neck organs in non-smokers was also demonstrated with results consistent with those for active smokers. There is little data on the effects of SHS in patients previously treated for squamous cell carcinomas of the head and neck.

Objective

The purpose of this study was to prospectively evaluate the role of SHS on recurrence and survival in treated head and neck cancer patients.

Methods

We conducted a prospective cohort study to examine the association between self-reported SHS exposure and the risk of recurrence and mortality in patients treated for squamous cell cancers of the head and neck in a longitudinal fashion. Patients filled out an exhaustive smoking questionnaire on presentation and abbreviated questionnaires at each follow-up visit, which occurred every 6 months. Primary outcome measures were recurrence, development of a second primary malignancy, and recurrence-free survival. Chi square analysis was used to assess the association between SHS and the primary outcomes. A multivariate binary logistic regression analysis was applied to determine the independent predictors of recurrence. Cox proportional hazards and Kaplan Meier modeling were employed to assess the possible relationships between SHS exposure and time to develop the primary outcomes.

Results

Untreated new patients with a histologically confirmed diagnosis of first primary SCC of the UADT (defined as cancer of the oral cavity, the oropharynx, the hypopharynx, and the larynx) were recruited. Patients seen at The University of Texas Medical Branch (UTMB) Head and Neck oncology clinic from 1988 to 1996 were considered as cases in this study. One hundred and thirty-five patients were enrolled in the study. The median follow-up time for the sample was 54 months (3.92 years). Complete records were achieved for 92% of patients, thus 124 patients were included in the final analysis. SHS significantly correlated with recurrence and recurrence-free survival. The rate of recurrence was 46% in the group exposed to SHS and 22% in the non-exposed group. Based on multivariate binary logistic regression analysis, SHS exposure was detected as a significant independent predictor for recurrence (HR = 3.00 [95% CI 1.18–7.63]). Kaplan-Meier analysis demonstrated that patients who were not exposed to SHS had a statistically significant longer recurrence-free survival (log-rank P = 0.029). The mean survival for non SHS-exposed patients was 76 [63–89] months versus 54 [45–63] months for those exposed to SHS.

Conclusions

SHS exposure is an independent predictor of recurrence and survival after head and neck cancer treatment. These results support the importance and efforts of reducing smoking at home in in the work-place.

Continued smoking after a cancer diagnosis: a longitudinal study of intentions and attempts to quit

PURPOSE

Continued smoking after a cancer diagnosis is associated with poor treatment outcomes and reduced life expectancy. We aimed to identify the stability of smoking status after diagnosis including quit attempts and quit intentions.

METHODS

Participants with a first primary cancer diagnosis were recruited via two state-based registries in Australia. Questionnaires were mailed at approximately 6 months (T1), 1 year (T2), 2 years (T3), and 3.5 years (T4) post-diagnosis. Smoking status and quitting intentions were assessed at each time point.

RESULTS

A cohort of 1444 people was recruited. People who indicated that they were more than 9 months post-diagnosis are excluded from analysis, leaving 1407 eligible study participants. Sixty-six (37%) of the 178 self-reported smokers at diagnosis had quit in the 6-month post-diagnosis (T1), the remaining 112 (63%) reported being a current smoker. Of the smokers at T1, 40% intended to quit: with 8% having quit smoking by T2; 11% quit by T3; 12% quit by T4. Of those who reported at T1 that they intended to quit in the next 6 months, 10% or fewer reported having quit at any subsequent time point. Quitting attempts decreased in frequency over time post-diagnosis. Less than 15% of respondents who had quit at or shortly before diagnosis reported relapse to smoking at each time point.

CONCLUSIONS

The majority of smokers diagnosed with cancer continue to smoke beyond diagnosis, even in the context of an intention to quit and attempts to do so. Cancer survivors who smoke remain motivated to quit well beyond the initial diagnosis.

IMPLICATIONS FOR CANCER SURVIVORS

There are clear positive clinical effects of smoking cessation for those who have undergone treatment for cancer, both for short-term treatment outcomes, and for long-term survivorship. Given the substantial rates of continued smoking among those who report smoking at diagnosis and their continued attempts to quit during survivorship, there is a need for improved cessation support initiatives for people diagnosed with cancer. These initiatives need to continue to be offered to smokers long after the initial diagnosis and treatment.

Sociodemographic correlates of cancer fatalism and the moderating role of religiosity: Results from a nationally-representative survey

In general, it has been found that cancer fatalism is negatively associated with important cancer prevention and control behaviors, whereas religiosity is positively associated with these behaviors. Yet, the notion that religiosity gives rise to fatalistic beliefs that may discourage health behaviors is deeply ingrained in the public health literature. In addition, racial/ethnic group membership is associated with higher reports of cancer fatalism, though this association may be confounded by socioeconomic status (SES). A better understanding of the relationships between racial/ethnic group membership, SES, and religiosity may contribute to the development of effective interventions to address cancer fatalism and improve health behaviors. In this study, we examined associations between racial/ethnic group membership, SES, and cancer fatalism as the outcome. In addition, we tested whether religiosity (as measured by religious service attendance) moderated these relationships.

Tobacco Use among Adult Muslims in the United States

BACKGROUND

Compared with the general United States (US) population, Muslims in the US exhibit elevated rates of tobacco use. As a result, they might be at a higher risk for preventive disease and premature death as compared with the general US population.

OBJECTIVE

This study investigated the Social Cognitive Theory (SCT) factors that are associated with tobacco use among a sample of adult Muslims in the US.

METHODS

Data were collected (November 2016-March 2017) using a cross-sectional, on-line survey from a convenience sample of adult (≥ 18 years) US Muslims. Participants with a lung cancer history were excluded. Associations between SCT factors and tobacco use were investigated with bivariate analyses and multinomial logistic regression models.

RESULTS

Eligible participants (n = 271) from 30 states completed the survey; 52.8% reported current tobacco use. A higher rate of current tobacco use was reported by men (62.8%) as compared to women (41.3%), x2(1, N = 271) = 12.49, p < .001. In terms of cognitive factors, individuals who (1) expected more personal consequences for tobacco use on health, and (2) had more confidence regarding ability to abstain from tobacco use, were less likely to report current tobacco use. In terms of environmental factors, individuals whose family members did not use tobacco were less likely to report current tobacco use.

CONCLUSION

The study findings suggest that family-oriented interventions emphasizing self-efficacy and personal consequences to prevent tobacco use can potentially be effective in reducing tobacco use rates in the adult US Muslim population.

Health behaviors among unaffected participants following receipt of variants of uncertain significance in cardiomyopathy-associated genes

Purpose

Studies on returning variants of uncertain significance (VUS) have predominantly included patients with a personal or family history of cancer and cancer-associated gene VUS. This study examined health behaviors amongst participants with cardiomyopathy-associated gene VUS, but without a personal history of cardiomyopathy.

Methods

Sixty-eight eligible participants without apparent cardiomyopathy who received VUS in cardiomyopathy-associated genes completed a survey of health behaviors, disclosure, distress, uncertainty, positive experiences, decisional conflict, and perceived value. Medical records of participants who reported cardiac testing because of their VUS were reviewed for testing indication(s).

Results

Two participants had cardiac testing due to their VUS alone. Four had cardiac testing because of their VUS and other clinical indications and 12 changed health behaviors, including one participant who was subsequently diagnosed with cardiomyopathy. Distress, uncertainty, and decisional conflict were low (means= 1.2, 4.2, 24.5; scale ranges= 0–30, 0–45, 15–75, respectively), and positive experiences and perceived value were moderate (means= 12.4, 14.4; scale range= 0–20, 4–20, respectively). Greater perceived value was associated with greater likelihood to engage in health behaviors (p= 0.04).

Conclusion

VUS can be returned to apparently unaffected individuals with modest use of healthcare resources, minimal behavioral changes, and favorable psychological reactions.

Associations between the smoking-relatedness of a cancer type, cessation attitudes and beliefs, and future abstinence among recent quitters

OBJECTIVE

Smoking after a diagnosis of cancer can negatively impact treatment outcomes and quality of life. It is important that patients quit smoking and remain abstinent regardless of cancer type. Some cancer types (eg, lung) have stronger links to smoking as a cause than do others (eg, colorectal). The aims of this study were to (1) assess associations between smoking-relatedness of the cancer type with beliefs and attitudes concerning smoking abstinence (eg, confidence, self-efficacy), and (2) assess these variables as predictors of future abstinence.

METHODS

In this secondary analysis, cancer patients (N = 357) who quit smoking within the previous 90 days were assigned a code of 3, 2, or 1 according to the cancer type's level of smoking-relatedness: Very related (n = 134, thoracic and head and neck), Somewhat related (n = 93, acute myeloid leukemia, bladder, cervix, colorectal, esophageal, kidney, liver, pancreas, and stomach), and Unlikely related (n = 137, all other cancer types).

RESULTS

Smoking-relatedness was positively associated with plan to stay smoke-free, maximum confidence in being smoke-free in 6 months, higher abstinence self-efficacy, and lower expected difficulty in staying smoke-free. Each of the 4 beliefs and attitude variables predicted abstinence 2 months later. Smoking-relatedness also predicted abstinence in a univariate model, but not in a multivariable model with the belief and attitude variables. Using backwards stepwise procedures, the final model included plan to stay smoke-free, confidence in being smoke-free, and abstinence self-efficacy.

CONCLUSION

These results are consistent with our conceptualization of cessation motivation differing by smoking-relatedness of the cancer type and predicting future abstinence.

Why Don't Cancer Survivors Quit Smoking? An Evaluation of Readiness for Smoking Cessation in Cancer Survivors

Background

Cancer survivors have a high rate of participation in cigarette-smoking cessation programs but their smoking-abstinence rates remain low. In the current study, we evaluated the readiness to quit smoking in a cancer-survivor population.

Methods

Cross-sectional data survey conducted among 112 adult cancer survivors who smoked cigarettes in Tennessee. Analyses were conducted using a two-sample t-test, χ² test, Fishers Exact test, and multivariable logistic regression with smoker’s readiness to quit as the dependent variable. We operationally defined a smoker not ready to quit as anyone interested in quitting smoking beyond the next 6 months or longer (or not at all), as compared to those that are ready to quit within the next 6 months.

Results

Thirty-three percent of participants displayed a readiness to quit smoking in the next 30 days. Smokers ready to quit were more likely to display high confidence in their ability to quit (OR = 4.6; 95% CI, 2.1–9.7; P < 0.0001) than those not ready to quit. Those ready to quit were nearly five times more likely to believe smoking contributed to their cancer diagnosis (OR = 4.9; 95% CI, 1.1–22.6; P = 0.0432). Those ready to quit were also much more likely to attempt smoking cessation when diagnosed with cancer (OR = 8.9; 95% CI, 1.8–44.3; P = 0.0076) than smokers not ready to quit. Finally, those ready to quit were more likely to endorse smoking more in the morning than other times of the day, compared to those not ready to quit (OR = 7.9; 95% CI, 1.5–42,3; P = 0.0148), which increased odds of readiness to quit within the next 6 months.

Conclusions

Despite high participation in smoking-cessation programs for cancer survivors, only one-third of participants were ready to quit. Future research is needed to develop programs targeting effective strategies promoting smoking cessation among cancer survivors who are both ready and not ready to quit smoking.

Topic Modeling of Smoking- and Cessation-Related Posts to the American Cancer Society's Cancer Survivor Network (CSN): Implications for Cessation Treatment for Cancer Survivors Who Smoke

Introduction

Smoking is a risk factor in at least 18 cancers, and approximately two-thirds of cancer survivors continue smoking following diagnosis. Text mining of survivors' online posts related to smoking and quitting could inform strategies to reduce smoking in this vulnerable population.

Methods

We identified posts containing smoking/cessation-related keywords from the Cancer Survivors Network (CSN), an online cancer survivor community of 166 000 members and over 468 000 posts since inception. Unsupervised topic model analysis of posts since 2000 using Latent Dirichlet Allocation extracted 70 latent topics which two subject experts inspected for themes based on representative terms. Posterior analysis assessed the distribution of topics within posts, and the range of themes discussed across posts.

Results

Less than 1% of posts (n = 3998) contained smoking/cessation-related terms, and covered topics related to cancer diagnoses, treatments, and coping. The most frequent smoking-related topics were quit smoking methods (5.4% of posts), and the environment for quitters (2.9% of posts), such as the stigma associated with being a smoker diagnosed with cancer and lack of empathy experienced compared to nonsmokers. Smoking as a risk factor for one's diagnosis was a primary topic in only 1.7% of smoking/cessation-related posts.

Conclusions

The low frequency of smoking/cessation-related posts may be due to expected criticism/stigma for smoking but may also suggests a need for health care providers to address smoking and assist with quitting in the diagnostic and treatment process. Topic model analysis revealed potential barriers that should be addressed in devising clinical or population-level interventions for cancer survivors who smoke.

Implications

Although smoking is a major risk factor for cancer, little is known about cancer patients' or survivors' views or concerns about smoking and quitting. This study used text mining of posts to an online community of cancer patients and survivors to investigate contexts in which smoking or quitting is discussed. Results indicated that smoking and quitting discussions were relatively rare, but nevertheless provide insight into barriers that may need to be addressed in cessation interventions for survivors.

Fate and the clinic: a multidisciplinary consideration of fatalism in health behaviour

The role of fatalism in health behaviour has stirred significant controversy in literature across several disciplines. Some researchers have demonstrated a negative correlation between fatalistic beliefs and healthy behaviours such as cancer screening, arguing that fatalism is a barrier to health-seeking behaviours. Other studies have painted a more complicated picture of fatalistic beliefs and health behaviours that ultimately questions fatalism's causality as a distinct factor. Unpacking this debate raises thought-provoking questions about how epistemological and methodological frameworks present particular pictures about the connections between belief, race, class and behaviour. The discussion surrounding fatalism illuminates larger tensions between structural and cultural determinants of health behaviour. This article argues for a more rigorous delineation of culture and structure and suggests that future theory-informed and ethnographic research may more precisely parse the role of fatalism in health attitudes, beliefs and behaviours.

Contextual and stress process factors associated with head and neck cancer caregivers' physical and psychological well-being

Head and neck cancer (HNC) caregivers are especially vulnerable to poor outcomes because the HNC patients are at high risk for physical and functional impairments. This study examines contextual and stress process variables potentially associated with HNC caregivers' physical and psychological well-being. Patient-caregiver variables included socio-demographics, primary stressors (caregiving, patient clinical characteristics, HNC-related symptoms/dysfunction), secondary stressors (caregiver employment, childcare responsibilities and sleep duration <7 hr), appraisal, and response (physical activity). General linear models modeled caregiver well-being, along with depression and anxiety. A total of 33 patient-caregiver dyads were included. Most caregivers were female (81.8%) and patient spouses/partners (72.7%). Factors significantly associated with better caregiver physical well-being included caregiver older age, <2 comorbidities, ≥7 hr of sleep, ≥3 days/week physical activity, and patient swallowing and speech dysfunction. Factors significantly associated with better caregiver mental health functioning were less patient social dysfunction and less perceived caregiving burden. Short nighttime sleep, higher caregiver burden, and <3 days/week physical activity were also significantly related to caregivers' depression and anxiety. Results suggested caregiver behaviors and perceived burden, along with patient HNC concerns are linked with caregiver well-being. These behavioral, cognitive, and patient factors should be incorporated into caregiver screening tools or targeted with behavioral interventions to improve caregiver well-being.

Cancer-related disease factors and smoking cessation treatment: Analysis of an ongoing clinical trial

OBJECTIVE

Smoking cessation treatment should be an important aspect of cancer care. In this study, we evaluated whether cancer-related disease factors adversely influence smoking cessation treatment.

METHODS

Smokers with cancer (within 5 years of diagnosis, any tumor site) were recruited for an ongoing trial of varenicline for smoking cessation. Disease factors, assessed at baseline, included tumor site, cancer treatment, time since diagnosis, and health-related quality of life. Medication adherence was defined by 132 of 165 pills taken and counseling adherence was defined by 4 of 4 behavioral counseling sessions attended. Abstinence was bioverified at Week 12. Using logistic regression analysis, we assessed the relationship between disease factors and 12-week medication adherence, counseling adherence, and abstinence.

RESULTS

Of 144 participants, 56% were medication adherent, 74% were counseling adherent, and 39% were abstinent. Health-related quality of life predicted medication adherence (OR: 1.08, 95% CI, 1.01-1.16, P = .019, d = 0.20) but not counseling adherence or 12-week abstinence. Tumor site, cancer treatment, and time since diagnosis did not predict any smoking cessation treatment outcomes.

CONCLUSIONS

Cancer-related disease factors did not predict cancer survivors' engagement or success in smoking cessation treatment. Findings support National Comprehensive Cancer Network Clinical Practice guidelines that recommend smoking cessation treatment for all smokers with cancer, regardless of time since diagnosis.

Fatalism and exposure to health information from the media: examining the evidence for causal influence

Fatalistic attitudes have a negative impact on a broad variety of health behaviors and behavioral determinants of health. A growing body of research has documented an association between media exposure and fatalism; however, scholarship has not been able to ascertain the causal direction. This review synthesizes the current state of the literature. A major finding is that most studies purporting to assess the relationship between media exposure and fatalism use conflated measures of fatalism. Among those that use an appropriate measure, there is some evidence that increased exposure to media increases fatalism. Although there is a substantive theoretical rationale for such effects, more research is needed to make a definitive claim and to explain the mechanism for such effects.

Anxiety After Diagnosis Predicts Lung Cancer-Specific and Overall Survival in Patients With Stage III Non-Small Cell Lung Cancer: A Population-Based Cohort Study

CONTEXT

The question as to whether anxiety and depression are related to mortality in patients with lung cancer is inconclusive.

OBJECTIVES

Therefore, the present study is examining associations of anxiety and depression in a large representative sample of patients with Stage III non-small cell lung cancer.

METHODS

Patients (n = 684) were routinely assessed for anxiety and depression with the PsychoSocial Screen for Cancer questionnaire after diagnosis of lung cancer and before treatment initiation between 2004 and 2010. Survival data were retrieved in May 2012. Cox proportional hazards regression analyses had been used as statistical procedures allowing adjustment for demographic, biomedical, and treatment variables.

RESULTS

In analyses controlling for demographic, biomedical, and treatment prognosticators, anxiety but not depression was associated with increased lung cancer-specific (hazard ratio 1.04; 95% confidence interval 1.01-1.07; P = 0.035) and all-cause (hazard ratio 1.04; 95% confidence interval 1.01-1.07; P = 0.005) mortality. Secondary analyses revealed a confounder effect of performance status on the association between depression and mortality, such that the removal of performance status identified a significant relationship of depression on lung cancer-specific and all-cause mortality.

CONCLUSION

In a large population-based sample of patients with non-small cell lung cancer analyses demonstrated associations of anxiety with mortality, adding to the evidence that psychosocial factors might play a role in disease progression in this patient group. Because emotional distress is associated with continued smoking and lack of success of smoking cessation attempts, psychological interventions potentially could influence length of survival in lung cancer patients.

Use of Electronic Cigarettes Among U.S. Adults With Medical Comorbidities

INTRODUCTION

Electronic cigarette (e-cigarette) use is rising in the U.S. Smokers with comorbidities may increasingly use e-cigarettes if they believe e-cigarettes reduce smoking-related harm. This study examined e-cigarette use among adults with medical comorbidities.

METHODS

In 2016, this study analyzed 68,136 U.S. adults in the 2014 and 2015 National Health Interview Survey. Prevalent e-cigarette use by medical comorbidities and adjusted odds of e-cigarette use were calculated.

RESULTS

Among current cigarette smokers, ever use of e-cigarettes was more often reported by adults with one or more medical comorbidity versus those without comorbidity (18-24 years: 73.5% vs 61.4%; 25-44 years: 60.6% vs 54.3%; 45-64 years: 46.5% vs 40.3%; ≥65 years: 35.2% vs 19.4%; all p<0.05). Current smokers aged 25-64 years with one or more comorbidity reported current e-cigarette use more often than those without comorbidity (25-44 years, 17.8% vs 14.3%, p=0.03; 45-64 years, 15.9% vs 11.5%, p=0.02). Current smokers with chronic obstructive pulmonary disease, asthma, and cardiovascular disease had higher odds of ever e-cigarette use versus those without comorbidity. Current smokers with asthma and cardiovascular disease had higher odds of current e-cigarette use. Former smokers with chronic obstructive pulmonary disease had higher odds of ever and current e-cigarette use and former smokers with cancer had lower odds of current e-cigarette use.

CONCLUSIONS

E-cigarette use by current and former smokers with medical comorbidities is substantial, especially among individuals with chronic lung or cardiovascular disease. Clinicians should routinely ask these patients about e-cigarette use, actively consider all pathways to help their patients quit combustible cigarettes, and recommend evidence-based treatments.

Smoking status and symptom burden in surgical head and neck cancer patients

OBJECTIVES/HYPOTHESIS

Head and neck squamous cell carcinoma (HNSCC) patients who smoke are at risk for poor treatment outcomes. This study evaluated symptom burden and clinical, sociodemographic, and psychosocial factors associated with smoking in surgical patients to identify potential targets for supportive care services.

STUDY DESIGN

Cross-sectional survey.

METHODS

Individuals with HNSCC of the oral cavity, larynx, or pharynx were recruited from two cancer centers and completed questionnaires assessing smoking status (never, former, current/recent), patient characteristics, and symptoms before surgery.

RESULTS

Of the 103 patients enrolled, 73% were male, 52% were stage IV, 41% reported current/recent smoking, and 37% reported former smoking. Current/recent smokers were less likely than former smokers to have adequate finances (53% vs. 89%, P = .001) and be married/partnered (55% vs. 79%, P = .03). Current/recent smokers were also more likely than both former and never smokers to be unemployed (49% vs. 40% and 13%, respectively, all P = .02) and lack health insurance (17% vs. 5% and 13%, respectively, all P ≤.04). Fatalistic beliefs (P = .03) and lower religiosity (P =.04) were more common in current/recent than never smokers. In models adjusted for sociodemographic/clinical factors, current/recent smokers reported more problems than former and never smokers with swallowing, speech, and cough (P ≤.04). Current/recent smokers also reported more problems than never smokers with social contact, feeling ill, and weight loss (P ≤ .02).

CONCLUSIONS

HNSCC patients reporting current/recent smoking before surgery have high-risk clinical and sociodemographic features that may predispose them to poor postoperative outcomes. Unique symptoms in HNSCC smokers may be useful targets for patient-centered clinical monitoring and intervention.

Treating Nicotine Dependence and Preventing Smoking Relapse in Cancer Patients

INTRODUCTION

Despite the well-documented harmful effects of smoking, many cancer patients continue to smoke. Smoking cessation is critical to address in this population given the associated increase in treatment toxicity, risk of second primary tumors, decrease in treatment response and higher disease-specific and all-cause mortality with continued smoking following a cancer diagnosis. This review seeks to summarize the latest recommendations and guidelines on smoking cessation treatment for patients diagnosed with cancer, and the evidence behind those recommendations.

AREAS COVERED

We reviewed the latest evidence for smoking cessation treatments for cancer patients and the clinical guidelines and recommendation available for oncologists and health care providers. The unique aspects of nicotine dependence among patients diagnosed with cancer, and key challenges and barriers that cancer survivors and health care providers experience when considering smoking cessation treatments, and available clinical resources, are also discussed. Lastly, the authors summarize future directions in the field of smoking cessation treatment for cancer patients.

EXPERT COMMENTARY

While there are areas of improvement in research of smoking cessation treatment for cancer patients, critical under-explored areas remain. Nonetheless, providers should adhere to the NCCN guidelines and offer a brief counseling intervention to motivate patients to quit smoking when appropriate resources are not available.

Helping patients to reduce tobacco consumption in oncology: a narrative review

The present overview focuses on evidence of smoking cessation approaches in oncology settings with the aim to provide health personnel a critical perspective on how to help their patients. This narrative review is structured in two main sections: the first one describes the psycho-cognitive variables involved in the decision to continue smoking after a cancer diagnosis and during the treatment; the second section relates methods and tools may be recommended, being evidence-based, to support smoking cessation in oncology settings. Active smoking increases not only susceptibility to common cancers in the general population, but also increases disease severity and comorbidities in cancer patients. Nowadays, scientific evidence has identified many strategies to give up smoking, but a lack of knowledge exists for treatment of nicotine dependence in the cancer population. Health personnel is often ambiguous when approaching the problem, while their contribution is essential in guiding patients towards healthier choices. We argue that smoking treatments for cancer patients deserve more attention and that clinical features, individual characteristics and needs of the patient should be assessed in order to increase the attempts success rate. Health personnel that daily work and interact with cancer patients and their caregivers have a fundamental role in the promotion of the health changing. For this reason, it is important that they have adequate knowledge and resources in order to support cancer patients to stop tobacco cigarette smoking and promoting and healthier lifestyle.

Systematic Review of Tobacco Use after Lung or Head/Neck Cancer Diagnosis: Results and Recommendations for Future Research

Tobacco use after cancer diagnosis is associated with adverse cancer outcomes, yet reliable prevalence estimates for this behavior are lacking. We conducted a systematic literature review of the prevalence of current tobacco use among individuals with a history of lung or head/neck cancer (CRD #42012002625). An extensive search of electronic databases (MEDLINE, EMBASE, Cochrane Library, CINAHL, PsycINFO, and Web of Science) identified 7,777 potentially relevant articles published between 1980 and 2014 and 131 of these yielded pertinent information. Aggregating results across heterogeneous study designs and diverse patient samples, the overall mean prevalence rate of current tobacco use (mostly cigarette smoking) was 33.0% (median, 31.0%). Among current tobacco users at cancer diagnosis, the mean prevalence rate of current tobacco use (mostly cigarette smoking) was 53.8% (median, 50.3%). In many cases, an operational definition of "current" tobacco use was absent, and biochemical verification of self-reported smoking status was infrequent. These and other observed methodologic limitations in the assessment and reporting of cancer patients' tobacco use underscore the necessity of uniform tobacco use assessment in future clinical research and cancer care.

Factors That Predict Persistent Smoking of Cancer Survivors

We conducted this cross-sectional study to elucidate factors that predict persistent smoking of the Korean cancer survivors. The subjects were 130 adult (≥19 yr old) cancer survivors who were smokers at the diagnosis of cancer and have participated in the Korean National Health and Nutrition Examination Surveys conducted from 2007 to 2011. We categorized them into the persistent smokers and the quitters, according to change in smoking status between the time of cancer diagnosis and the time of the survey. Factors associated with persistent smoking were evaluated using the multiple logistic regression analysis. During 7.52 yr (standard deviation = 0.34) after the cancer diagnosis, 59.6% of the 130 cancer survivors have continued to smoke. After adjusting for covariates, following factors were independently associated with the risk of persistent smoking: female, low income, high-risk alcohol use, high body mass index (≥ 25 kg/m(2)), presence of household members who smoke, and longer duration of smoking. Alcohol Use Disorders Identification Test showed a positive association with the risk of persistent smoking (P for trend = 0.012). In conclusion, more efforts for smoking cessation should be in place for the cancer survivors with those risk factors associated with the persistent smoking.

Tobacco use and surgical outcomes in patients with head and neck cancer

BACKGROUND

Tobacco use is a risk factor for head and neck cancer, but effects on postoperative outcomes are unclear.

METHODS

Patients with head and neck cancer (n = 89) were recruited before surgery. We assessed self-reported tobacco use status (never, former, or current) at study entry and recent tobacco exposure via urinary cotinine on surgery day. Outcomes included hospital length of stay (LOS) and complications.

RESULTS

Most participants reported current (32.6%) or former (52.8%) tobacco use; 43.2% were cotinine-positive on surgery day. Complications occurred in 41.6% and mean LOS was 4.0 and 8.8 days in patients who received low and high acuity procedures, respectively. Current and former smokers were over 6 times more likely to have complications than never smokers (p = .03). For high acuity procedures, LOS was increased in current (by 4.4 days) and former smokers (by 2.3 days; p = .02).

CONCLUSION

Tobacco use status is associated with postoperative complications and may distinguish at-risk patients.

Smoking is associated with pessimistic and avoidant beliefs about cancer: results from the International Cancer Benchmarking Partnership

Background:

Smoking cessation is the key cancer prevention behaviour for smokers; nonetheless, smokers can still benefit from earlier diagnosis of cancer. However, fewer smokers participate in screening despite their increased risk, which may reflect different beliefs about cancer.

Methods:

A UK population-representative sample of ⩾50 year-olds (n=6965) was surveyed using the Awareness and Beliefs about Cancer measure. These analyses examine six items on cancer beliefs (e.g., ‘cancer can often be cured'), and four on help-seeking barriers (e.g., ‘I would be too embarrassed').

Results:

Smokers were more likely to hold pessimistic cancer beliefs than never-smokers or former-smokers on four of six items. For example, 34% agreed ‘a cancer diagnosis is a death sentence', compared with 24% of non/former-smokers (P<0.001). More smokers (18%) than non/former-smokers (11%) would not want to know if they had cancer (P<0.01). The only barrier to symptomatic help-seeking differing by smoking status was ‘worry about what the doctor might find' (36% vs 28%, P<0.01). Associations were independent of demographics, self-rated health and cancer experience.

Conclusions:

Smokers held more pessimistic and avoidant beliefs about cancer, which could deter early-detection behaviour. A better understanding of these beliefs is needed to increase engagement in early diagnosis by this high-risk group.

Statement on smoking cessation in COPD and other pulmonary diseases and in smokers with comorbidities who find it difficult to quit

Chronic obstructive pulmonary disease (COPD), lung cancer, asthma and pulmonary tuberculosis are common pulmonary diseases that are caused or worsened by tobacco smoking. Growing observational evidence suggests that symptoms and prognosis of these conditions improve upon smoking cessation. Despite increasing numbers of (small) randomised controlled trials suggesting intensive smoking cessation treatments work in people with pulmonary diseases many patients are not given specific advice on the benefits or referred for intensive cessation treatments and, therefore, continue smoking.This is a qualitative review regarding smoking cessation in patients with COPD and other pulmonary disorders, written by a group of European Respiratory Society experts. We describe the epidemiological links between smoking and pulmonary disorders, the evidence for benefits of stopping smoking, how best to assess tobacco dependence and what interventions currently work best to help pulmonary patients quit. Finally, we describe characteristics and management of any "hardcore" smoker who finds it difficult to quit with standard approaches.

Prevalence of cigarette smoking among adult cancer survivors in Korea

PURPOSE

Cigarette smoking is associated not only with increased risk of cancer incidence, but also influences prognosis, and the quality of life of the cancer survivors. Thus, smoking cessation after cancer diagnosis is necessary. However, smoking behavior among Korean cancer-survivors is yet unknown.

MATERIALS AND METHODS

We investigated the smoking status of 23770 adults, aged 18 years or older, who participated in the Health Interview Survey of the Korea National Health and Nutrition Examination Survey from 2007 to 2010. Data on the cancer diagnosis and smoking history were obtained from an interview conducted by trained personals. "Cancer-survivor" was defined as anyone who has been diagnosed with cancer by a physician regardless of time duration since diagnosis. Smoking status was classified into "never-smoker", "former-smoker", and "current-smoker". Former-smoker was further divided into "cessation before diagnosis" and "cessation after diagnosis".

RESULTS

Overall, 2.1% of Korean adults were cancer-survivors. The smoking rate of Korean cancer-survivors was lower than that of non-cancer controls (7.8±1.3% vs. 26.4±0.4%, p<0.001). However, 53.4% of the cancer-survivors continued to smoke after their cancer diagnosis. In multivariate analysis, male gender [odds ratio (OR), 6.34; 95% confidence interval (CI), 2.62-15.31], middle-aged group (OR, 2.74; 95% CI, 1.12-6.72), the lowest income (OR, 4.10; 95% CI, 1.19-14.15), living with smoking family member(s) (OR, 5.49; 95% CI, 2.42-12.48), and the poor self-perceived health status (OR, 2.78; 95% CI, 1.01-7.71) were independently associated with persistent smoking among Korean cancer-survivors.

CONCLUSION

The smoking rate among Korean cancer survivors is low. However, the smoking cessation rate after the cancer diagnosis is also low. This mandates comprehensive and systematic intervention for smoking cessation among cancer-survivors.

Hardcore smokers: what do we know?

AIMS

The existence of smokers who are resistant to smoking cessation treatment has long been noted in the literature. There has been ongoing debate as to whether the proportion of these smokers is increasing as smoking prevalence rates stagnate. Studies define hardcore smokers inconsistently and within the context of specific illnesses, addiction, population, and/or theoretical paradigms. This review examines the existing literature related to hardcore smokers to develop a better understanding of what is known and not known about this group to guide smoking cessation treatment.

METHODS

PubMed MESH search and review of research publications from 1998 to 2012 (N=61).

RESULTS

Inconsistent definitions of hardcore smoking make it difficult to estimate prevalence rates and to identify specific characteristics of persistent smokers. Generally, persistent smokers have higher levels of nicotine dependence, are disproportionately from lower socioeconomic groups, start smoking at an earlier age, and are more likely to have a psychological co-morbidity.

DISCUSSION

Defining some smokers as hardcore is limiting. Targeted and tailored interventions for smoking cessation for persistent smoking have demonstrated effectiveness in a small number of studies. Treatment access barriers need to be addressed to improve the reach and effectiveness of cessation with persistent smokers. Efforts to limit early age initiation of tobacco use are a critical element in averting persistent smoking.

Perceptions of risk among childhood and young adult cancer survivors who smoke

PURPOSE

Despite the fact that childhood and young adult cancer survivors are at increased risk for chronic health problems as a result of their cancer treatment, many use tobacco, thereby increasing their risks. Perceptions of risk related to tobacco use can be targeted for interventions aimed at improving health behaviors for childhood, adolescent, and young adult cancer survivors. Understanding the covariates of perceptions of health risks among young adult survivors who smoke will help to determine targets for intervention.

METHOD

Three hundred seventy-four participants who were diagnosed with cancer prior to age 35, currently between 18 and 55 years of age, and current smokers were recruited as part of a larger smoking cessation study, Partnership for Health-2 (PFH-2). Data were collected by telephone survey.

RESULTS

Overall, women had the highest perception of risk for serious health problems, a second cancer, and heart problems. Additionally, those participants who were dependent on nicotine endorsed that they were at higher risk of serious health problems and second cancers, but not heart problems. Finally, Hodgkin lymphoma survivors reported that they were at increased risk for second cancers and heart problems compared to their “healthy” peers.

CONCLUSION

Young adult cancer survivors who smoke correctly perceived some of their increased health risks. Additional motivation and education is needed for those young adult cancer survivors who perceive their increased health risks yet continue to smoke. Further education is needed for young survivors so they have a fully appropriate sense of risk, especially as it relates to their tobacco use.

Prevalence and correlates of smoking and cessation-related behavior among survivors of ten cancers: findings from a nationwide survey nine years after diagnosis

BACKGROUND

Smoking is detrimental to recovery and survival from cancer, but many cancer survivors continue to smoke. Information is lacking on smoking patterns of survivors many years after diagnosis and correlates of smoking status and patterns, likelihood of quitting, and intentions to quit.

METHODS

Cross-sectional analyses were conducted among survivors of 10 cancers recruited by stratified random sampling from cancer registries in a nationwide, longitudinal, quality-of-life study (n = 2,938).

RESULTS

Approximately 9 years after diagnosis, 9.3% of all survivors were current (past 30-day) smokers. Smoking prevalence was highest among survivors of bladder (17.2%), lung (14.9%), and ovarian (11.6%) cancers. Most current smokers (83%) smoked daily, averaging 14.7 cigarettes per day (cpd). Forty percent of daily smokers smoked more than 15 cpd. Nondaily smokers smoked a mean of 10.9 days in the last 30 days and averaged 5.7 cpd on smoking days. Current smoking was associated with younger age, lower education and income, and greater alcohol consumption. Quitting after diagnosis was associated with having a smoking-related cancer. Roughly, a third of current smokers intended to quit, 40% within the next month. The odds of intending to quit were lower if survivors were married, older, or smoked more.

CONCLUSIONS

This population-based study indicated that smoking can persist long after initial diagnosis and at high levels and identified characteristics associated with quitting and intentions to quit.

IMPACT

Findings can be used to identify survivors most at risk for continued smoking and to inform tailoring of cessation treatments for survivors.
