RESUMO

INTRODUCTION: People with cancer who smoke exhibit greater cigarette dependence than people without cancer who smoke, a crucial factor in smoking cessation. Research is limited on the predictive potential of the Fagerström Test for Cigarette Dependence (FTCD) and the Heaviness of Smoking Index (HSI) on smoking abstinence in cancer patients undergoing smoking cessation treatment. METHODS: We analyzed data from 5,934 cancer patients seeking smoking cessation treatment at The University of Texas MD Anderson Cancer Center (female 52.08%; Mean age = 55.52, SD = 11.17). We evaluated the predictive accuracy of FTCD and HSI on abstinence at 3-, 6-, and 9-months from first consultation, and assessed the concordance between these tools in measuring cigarette dependence using Cohen's kappa test and different correlation and regression models. We also analyzed variations across sex at birth and race/ethnicity. RESULTS: Both the FTCD and the HSI demonstrated comparable predictive accuracy for smoking cessation at all follow-ups, with neither showing high accuracy (Areas Under the Curve scores around 0.6). Concordance analysis revealed substantial agreement between FTCD and HSI scores (Cohen's kappa ~ 0.7), particularly at lower levels of dependence. However, this agreement varied by race, with reduced concordance observed in Non-Hispanic Blacks. CONCLUSIONS: Our results indicate that both the FTCD and HSI are effective tools for predicting smoking cessation in cancer patients, with the HSI offering a less burdensome assessment option. Nevertheless, the findings suggest the need for tailored approaches in assessing cigarette dependence that could predict smoking cessation more accurately, considering racial differences. IMPLICATIONS: The burden of assessing cigarette dependence in cancer care settings can be reduced by using the HSI instead of the FTCD. In addition, both instruments could be substantially interchanged and used for meta-analytic studies examining dependence and abstinence, but race/ethnicity should be considered.

RESUMO

Importance: Most people who smoke do not quit on their initial attempt. Objective: To determine the best subsequent strategy for nonabstinence following initial treatment with varenicline or combined nicotine replacement therapy (CNRT). Design, Setting, and Participants: Using a double-blind, placebo-controlled, sequential multiple assignment randomized trial, 490 volunteers were randomized to receive 6 weeks of varenicline or CNRT. After 6 weeks, nonabstainers were rerandomized to continue, switch, or increase medication dosage for 6 additional weeks. The study was conducted from June 2015 through October 2019 in a Texas tobacco treatment clinic. Interventions: The initial treatment was 2 mg/d of varenicline or the combined replacement therapy of a 21-mg patch plus 2-mg lozenge. The rerandomized participants either continued with their initial therapies, switched between varenicline and CNRT, or increased dosages either to 3-mg or more of varenicline or to a 42-mg patch and lozenges. All received weekly brief counseling. Main Outcomes and Measures: Biochemically verified 7-day point prevalence abstinence at the end of treatment at 12 weeks. Results: The 490 randomized participants (210 female [43%], 287 non-Hispanic White [58%], mean age, 48.1 years) smoked an average of 20 cigarettes per day. After the first phase, 54 participants in the CNRT group were abstinent and continued their therapy; of the 191 who were not abstinent, 151 were rerandomized, and the 40 who did not return for rerandomization were assigned to continue their initial CNRT condition in phase 2. The end-of-treatment abstinence rate for the 191 phase 1 nonabstainers was 8% (95% credible interval [CrI], 6% to 10%) for the 90 (47%) who continued at the dosage condition, 14% (CrI, 10% to 18%) for the 50 (33%) who increased their dosage, and 14% (95% CrI, 10% to 18%) for the 51 (34%) who switched to varenicline (absolute risk difference [RD], 6%; 95% CrI, 6% to 11%) with more than 99% posterior probability that either strategy conferred benefit over continuing the initial dosage. After the first phase, 88 participants in the varenicline group were abstinent and continued their therapy; of the 157 who were not abstinent, 122 were rerandomized and 35 who did not return for rerandomization were assigned to continue with the varenicline condition. The end-of-treatment abstinence rate for the 157 phase 1 nonabstainers was 20% (95% CrI, 16% to 26%) for the 39 (32%) who increased their varenicline dosage, 0 (95% CrI, 0 to 0) for the 41 (34%) who switched CNRT, and 3% (95% CrI, 1% to 4%) for the 77 (49%) who were assigned to the continued varenicline condition (absolute RD, -3%; 95% CrI, -4% to -1%) with more than 99% posterior probability that continuing varenicline at the initial dosage was worse than switching to a higher dosage. Furthermore, increasing the varenicline dosage had an absolute RD of 18% (95% CrI, 13% to 24%) and a more than 99% posterior probability of conferring benefit. The secondary outcome of continuous abstinence at 6 months indicated that only increased dosages of the CNRT and varenicline provided benefit over continuation of the initial treatment dosages. Conclusions and Relevance: For individuals who smoked but did not achieve abstinence after treatment with varenicline, increasing the dosage enhanced abstinence vs continuing, whereas for nonabstainers initially treated with CNRT, a dosage increase or switch to varenicline enhanced abstinence and may be viable rescue strategies.

RESUMO

BACKGROUND AND OBJECTIVES: We provide an initial characterization of e-cigarette use among adult cancer patients. METHODS: Data were collected between November 2020 and August 2022 at a comprehensive cancer center. RESULTS: Relatively few (4.59%) of the assessed patients (n = 47,117) reported ever using e-cigarettes. Over one-third of current e-cigarette users reported being current combustible cigarette users. DISCUSSION AND CONCLUSIONS: These data suggest that e-cigarette use is uncommon but associated with other tobacco use among adult cancer patients. SCIENTIFIC SIGNIFICANCE: This is among the first comprehensive surveys of adult cancer patient e-cigarette use that details the types of e-cigarette and other tobacco products used by this population.

RESUMO

Continuous tobacco use in cancer patients is linked to substantial healthcare costs due to increased risks and complications, whereas quitting smoking leads to improved treatment outcomes and cost reductions. Addressing the need for empirical evidence on the economic impact of smoking cessation, this study examined the association between smoking cessation and healthcare cost utilization among a sample of 930 cancer patients treated at The University of Texas MD Anderson Cancer Center's Tobacco Research and Treatment Program (TRTP). Applying conditional quantile regression and propensity scores to address confounding, our findings revealed that abstinence achieved through the TRTP significantly reduced the median cost during a 3-month period post-quitting by $1,095 (ß=-$1,095, p=0.007, 95%CI=[-$1,886, -$304]). Sensitivity analysis corroborated these conclusions, showing a pronounced cost reduction when outlier data were excluded. The long-term accrued cost savings from smoking cessation could potentially offset the cost of participation in the TRTP program, underscoring its cost-effectiveness. An important implication of this study is that by reducing smoking rates, healthcare systems can more efficiently allocate resources, enhance patient health outcomes, and lessen the overall cancer burden.

RESUMO

BACKGROUND: Smoking remains a major public health problem, and it is important to provide a variety of efficacious and appealing options to encourage smokers to quit smoking. Scheduled smoking is a method of gradual reduction, preparing smokers to quit by systematically reducing cigarette consumption according to a predetermined schedule that increases the time between cigarette consumption. Gradual reduction may be preferred to abrupt quitting, but the efficacy of this cessation approach is unclear. OBJECTIVE: This study aims, first, to evaluate the overall effectiveness of scheduled smoking alone, or in combination with precessation nicotine replacement therapy (NRT), versus standard NRT starting on the quit date with no prior smoking reduction and, second, to evaluate the impact of schedule compliance on the effectiveness of the intervention. METHODS: A total of 916 participants recruited from the Houston metropolitan area were randomly assigned to 1 of the following 3 groups: scheduled smoking plus a precessation nicotine patch (n=306, 33.4%), scheduled smoking only with no precessation patch (n=309, 33.7%), and enhanced usual care (n=301, 32.9%) control. The primary abstinence outcomes were carbon monoxide-verified, self-reported, 7-day point prevalence abstinence at 2 and 4 weeks after the quit date. Unadjusted and adjusted logistic regression analyses were performed to evaluate the intervention effect. Scheduled smoking was implemented using a handheld device for 3 weeks before quitting. This trial was not registered because data collection began before July 1, 2005. RESULTS: Results for the first aim showed no overall differences in abstinence among the 3 groups in both the unadjusted and adjusted models. However, the results for the second aim showed a clear effect on abstinence by schedule compliance at 2 and 4 weeks and 6 months after quitting (odds ratio [OR] 2.01, 95% CI 1.31-3.07), 4 weeks (OR 1.58, 95% CI 1.05-2.38), and 6 months (OR 1.68, 95% CI 1.04-2.64), with the differences at 2 and 4 weeks after quitting being the most robust. We also found that scheduled smoking was related to a reduction in nicotine withdrawal, negative affect, and craving when compared with the controls. CONCLUSIONS: Scheduled smoking, when combined with precessation use of NRT, can result in significantly higher abstinence rates than usual care (abrupt quitting with NRT), particularly in the early postquit phase (2 and 4 weeks after cessation) when smokers are compliant with the procedure. Scheduled smoking also produced a better overall quitting experience by reducing symptoms of nicotine withdrawal and craving, in comparison with usual care, which could encourage future quit attempts. Studies in this area should focus on the use of counseling or other methods to improve adherence.

RESUMO

BACKGROUND: Tobacco smoking is a major independent risk factor for chronic disease, and the prevalence of smoking among people with behavioral health disorders is 2-fold in comparison with the general population. Smoking rates remain high for various subgroups within the Latine community, the largest ethnic minority group in the United States. Acceptance and commitment therapy (ACT) is a theoretically sound and clinically validated therapeutic approach for several behavioral health conditions with growing evidence of its effectiveness for smoking cessation. Unfortunately, the evidence of ACT effectiveness for smoking cessation among Latine individuals is scarce, and none of the existing studies have tested a culturally targeted intervention for this population. OBJECTIVE: This study aims to address the co-occurrence of smoking and mood-related challenges among Latine adults via the development and testing of a culturally tailored ACT-based wellness program: Project PRESENT. METHODS: This study entails 2 phases. Phase 1 consists of the intervention development. Phase 2 entails the pilot testing of the behavioral intervention along with the administration of baseline and follow-up measures to 38 participants. Primary outcomes include feasibility of recruitment and retention, and treatment acceptability. Secondary outcomes are smoking status and depression and anxiety scores at end of treatment and 1-month follow-up. RESULTS: This study received institutional review board approval. Phase 1 outputs were the health counselors' treatment manual and participant guide. Recruitment was completed in 2021. Phase 2 outcomes will be determined after project implementation and data analyses are complete, which are expected by May 2023. CONCLUSIONS: Findings from this study will determine the feasibility and acceptability of an ACT-based, culturally relevant intervention for Latine adults who smoke and have probable depression and/or anxiety. We expect feasibility of recruitment, retention and treatment acceptability, and reductions in smoking status, depression, and anxiety. If feasible and acceptable, the study will inform large-scale trials, which will ultimately contribute to narrowing the gap between research and clinical practice for the co-occurrence of smoking and psychological distress among Latine adults.

RESUMO

IMPORTANCE: Improving treatment outcomes for smokers with major depressive disorder (MDD) can have significant public health implications. OBJECTIVE: To evaluate the safety and efficacy of smoking cessation pharmacotherapy among smokers with MDD. DESIGN: Secondary analysis of a randomized, double-blind, active- (nicotine patch) and placebo-controlled trial of 12 weeks of either varenicline or bupropion with a 12-week follow-up. PARTICIPANTS: Community volunteers 18-75 years of age; smoke 10+ cigarettes/day; with clinically stable MDD (N = 2635) or no psychiatric disorder (N = 4028), from 140 sites in 16 countries. INTERVENTION: Twelve weeks of pharmacotherapy (placebo [PLA], nicotine replacement therapy [NRT], bupropion [BUP], varenicline [VAR]) plus brief cessation counseling. MEASURE(S): Primary safety outcome: the occurrence of ≥1 treatment-emergent, moderate to severe neuropsychiatric adverse event (NPSAE). Primary efficacy outcome: biochemically confirmed continuous abstinence (CA) during the final 4 weeks of treatment (Weeks 9-12). RESULTS: A total of 6653 participants (56% female; 39% MDD) ~47 years old. Risk of NPSAEs did not differ by medication for MDD. MDD had higher risk (p < .0001) for NPSAEs than the NPC. Efficacy (6653; intent-to-treat): CA rates for MDD versus NPC respectively were 31.2% versus 38.0% VAR; 23.0% versus 26.1% BUP; 22.6% versus 26.4% NRT; and 13.4% versus 13.7% PLA but no differential treatment effect was noted within the cohorts. All active treatments differed from PLA but VAR showed the largest effect. CONCLUSIONS: Results suggest that for MDD smokers, inclusive of those with recurrent episode, varenicline plus counseling may be the best pharmacological option for the treatment of smoking given its greater efficacy effect size and similar risk of NPSAEs.

RESUMO

BACKGROUND AND OBJECTIVES: Bupropion extended-release (XL; once-daily dosing) has equal efficacy with the sustained-release (SR) formulation (twice-daily dosing) for treating depression, but no studies have compared the two formulations for the treatment of smoking. In a naturalistic open-label study, we compared the effectiveness and the adverse event profiles of XL and SR in treating cancer patients for smoking. METHODS: Cancer patients (N = 648) were prescribed bupropion XL (n = 454) or SR (n = 194) alone or in combination with nicotine replacement therapy (NRT) for treating smoking from September 2006 to December 2017. We analyzed 7-day point prevalence abstinence at end-of-treatment (EOT; 3 months postmedication initiation) and evaluated for noninferiority. We also analyzed the adverse event profile differences between the medications. RESULTS: There were no significant differences in abstinent rates at EOT between bupropion XL and SR when using intent-to-treat models, regardless of concomitant NRT. XL demonstrated noninferiority in treatment efficacy compared to SR when excluding those on combined treatment with NRT. Further, there were no significant differences in spontaneously reported adverse events between XL and SR. CONCLUSIONS: Our data did not reveal a difference between bupropion XL and SR formulations in terms of effectiveness or adverse event profiles among cancer patients prescribed bupropion alone or in combination with NRTs to quit smoking. SCIENTIFIC SIGNIFICANCE: In this first published direct comparison of their effectiveness and adverse event profiles, we found that bupropion XL is likely therapeutically equivalent to bupropion SR when treating smoking among cancer patients, and produces similar side effects.

RESUMO

OBJECTIVE: Suicidal ideation has increased among Latinx individuals in the last decade. Smoking increases the likelihood of suicidal ideation but work on Latinx smokers is minimal. Hazardous drinking and emotion dysregulation could be factors related to suicidal ideation among Latinx smokers, as has been evident in non-Latinx White samples. The current study sought to examine the main and interactive effects of emotion dysregulation and hazardous drinking in relation to suicidal ideation among Latinx daily-smokers. METHODS: Participants were 371 Spanish-speaking daily-smokers (58.8% female; Mage = 33.3; SDage = 9.8) recruited from the United States through Qualtrics. We used structural equation modeling (SEM) to test an interactive model of emotion dysregulation and hazardous alcohol consumption in relation to suicidal ideation; we also tested the effect of emotion dysregulation on suicidal ideation as a function of hazardous drinking status. RESULTS: Results indicated that latent emotional dysregulation was associated with greater suicidal ideation (p < 0.001); however, hazardous drinking was not related to suicidal ideation (p = 0.186). The interactive term of emotional dysregulation and hazardous drinking was significantly related to suicidal ideation (p = 0.017). Specifically, greater emotion dysregulation was significantly related to suicidal ideation among Latinx smokers who engaged in hazardous drinking (p < 0.001) but not those who did not engage in hazardous drinking (p = 0.123). CONCLUSIONS: The current findings suggest that smoking combined with hazardous drinking may be related to increased suicidal ideation among Latinx smokers. Findings are discussed in relation to the potential role of intervention strategies that focus on emotion dysregulation and hazardous drinking among Latinx current daily smokers to mitigate suicidal risk among this established health disparities population.

RESUMO

INTRODUCTION: Adoption of rigorous standards for reporting treatment fidelity is essential for advancing discovery, validation, and implementation of behavioral treatments. Whereas the NIH Behavior Change Consortium (BCC) developed an assessment tool to assess the quality of reporting and monitoring of treatment fidelity across health behavior change interventions, it has not yet been applied specifically to treatment fidelity in behavioral tobacco treatment trials. AIMS AND METHODS: We conducted a scoping review of peer-reviewed, clinical trials of behavioral adult tobacco treatment interventions published in English between 2006 and 2018. Using the BCC treatment fidelity checklist, articles were coded for the presence or absence of various treatment fidelity strategies within each of 5 domains: Design, Training, Delivery, Receipt, and Enactment. Eligible articles (N = 755) were coded by two independent coders. RESULTS: The proportion of reporting strategies varied within the fidelity domains, ranging from 5.2% to 96.3% in Design, 1.9% to 24.9% in Training, 2.6% to 32.3% in Delivery, 5.2% to 44.3% in Receipt, and 6.7% to 43.2% in Enactment. The mean proportion of adherence to treatment fidelity strategies within each domain was: Design (68%), Training (14%), Delivery (15%), Receipt (16%), and Enactment (25%). Only 11 studies achieved ≥80% reporting across >1 fidelity domain. There was no evidence for improvement in fidelity reporting across the 13-year time frame from the initial BCC publication to the present. CONCLUSIONS: These findings illustrate the lack of consistency in fidelity reporting in tobacco treatment trials and underscore the challenges faced in evaluating rigor and reproducibility, as well as interpretation and dissemination of findings. Recommendations are made for improving fidelity reporting in tobacco treatment trials. IMPLICATIONS: The SRNT Treatment Research Network sponsored a scoping review to summarize the current state of reporting treatment fidelity and make recommendations for best practices in reporting fidelity in tobacco treatment trials. The review identified a lack of consistency in fidelity reporting, illustrating the challenges faced in evaluating rigor, and reproducibility, as well as interpretation and dissemination of findings.

RESUMO

INTRODUCTION: This study aimed to assess the association between current smoking and gender identity among transgender individuals. METHODS: Data were collected using a cross-sectional survey distributed among transgender individuals attending the Houston Pride Festival and those seeking care at a local transgender health clinic. Relevant variables were compared between female-to-male (FTM) and male-to-female (MTF) transgender individuals using χ2, Fisher's exact, and two-sample t-tests, when appropriate. Gender identity was used to predict current smoking status using logistic regression, adjusting for other sociodemographic determinants. RESULTS: The study sample (N=132) comprised 72 MTF (54.5%) and 60 FTM (45.5%) transgender individuals. Mean age of participants was 31.8 years. The sample was racially and ethnically diverse: 45.8% Caucasian, 25.2% Hispanic/Latino, 16.8% African American, and 12.2% other. Current smoking prevalence was 26.7% and 13.9% among FTM and MTF individuals, respectively. Transgender individuals were more likely to self-report current smoking if they were FTM (OR=3.76; 95% CI: 1.17-12.06; p=0.026) or were insured (OR=4.49; 95% CI: 1.53-13.18; p=0.006). CONCLUSIONS: This study reports on important findings by examining intragroup differences in smoking behavior among the transgender population. However, further research is needed for tailoring smoking prevention and cessation interventions for transgender subgroups.

RESUMO

Research regarding cross-behavioral relationships between the cognitive mechanisms motivating health behavior change is lacking for cancer survivors. This study investigated these relationships to inform the development of multiple health behavior change (MHBC) interventions for this at-risk population. Eligible participants included cancer survivors attending an intake appointment for smoking cessation services. This cross-sectional survey study assessed participants' self-efficacy and motivation (stage of change) for smoking cessation and exercise, as well as self-reported health behaviors. Analyses evaluated cross-behavioral associations between cognitive mechanisms and their relationships with smoking and exercise behaviors. Seventy-six participants completed the survey questionnaire. The correlation between self-efficacy scores for smoking cessation and exercise was statistically significant (r = .45, 95% CI [.09, .67]), as were correlations between self-efficacy and reported levels of exercise ((r = .44, 95% CI [.20, .65]) strenuous); ((r = .36, 95% CI [.12, .59]) moderate), exercise self-efficacy and smoking behavior (r = -.27, 95% CI [-.46, -.05]), and smoking self-efficacy and smoking behavior (r = -0.41, 95% CI [-.61, -.18]). For cancer survivors, associations between exercise self-efficacy and smoking cessation self-efficacy may offer an opportunity to leverage MHBC; specifically, this positive association may facilitate exercise intervention in survivors seeking smoking cessation services..

RESUMO

Importance: Patients with cancer who smoke after diagnosis risk experiencing reductions in treatment effectiveness, survival rates, and quality of life, and increases in complications, cancer recurrence, and second primary cancers. Smoking cessation can significantly affect these outcomes, but to date comprehensive treatment is not widely implemented in the oncologic setting. Objectives: To describe a potential model tobacco treatment program (TTP) implemented in a cancer setting, report on its long-term outcomes, and highlight its importance to quality patient care. Design, Setting, and Participants: A prospective cohort of smokers was treated in the TTP at a comprehensive cancer center from January 1, 2006, to August 31, 2015. Data analysis was performed from November 2017 to December 2018. Participants included 3245 patients (2343 with current cancer; 309 with previous cancer; 593 with no cancer history) drawn from a population of 5061 smokers referred for treatment in the TTP. Reasons for exclusion included follow-up for a noncancerous disease, no medical consultation, smoked less than 1 cigarette per day; or died before the 9-month follow-up. Exposures: Treatment consisted of an in-person medical consultation, 6 to 8 in-person and telephone follow-up counseling sessions, and 10 to 12 weeks of pharmacotherapy. Main Outcomes and Measures: Primary outcome was 9-month 7-day point-prevalence abstinence evaluated using time-specific (3-, 6-, and 9-month follow-ups) and longitudinal covariate-adjusted and unadjusted regression models with multiple imputation, intention-to-treat, and respondent-only approaches to missing data. The Fagerström Test for Cigarette Dependence was used as a measure of dependence (possible range, 0-10; higher numbers indicate greater dependence). Results: Of the 3245 smokers, 1588 (48.9%) were men, 322 (9.9%) were of black race/ethnicity, 172 (5.3%) were of Hispanic race/ethnicity, and 2498 (76.0%) were of white race/ethnicity. Mean (SD) age was 54 (11.4) years; Fagerström Test for Cigarette Dependence score, 4.41 (2.2), number of cigarettes smoked per day, 17.1 (10.7); years smoked, 33 (13.2); and 1393 patients (42.9%) had at least 1 psychiatric comorbidity. Overall self-reported abstinence was 45.1% at 3 months, 45.8% at 6 months, and 43.7% at 9 months in the multiply imputed sample. Results across all models were consistent, suggesting that, in comparison with smokers with no cancer history, abstinence rates within this TTP program did not differ appreciably whether smokers had current cancer, were a cancer survivor, or had smoking-related cancers, with the exception of patients with head and neck cancer; the rates were higher at 9 months (relative risk, 1.31; 95% CI, 1.11-1.56; P = .001) and in longitudinal models (relative risk, 1.24; 95% CI, 1.08-1.42; P = .002). Conclusions and Relevance: In this study, mean smoking abstinence rates did not differ significantly between patients with cancer and those without cancer. These findings suggest that providing comprehensive tobacco treatment in the oncologic setting can result in sustained high abstinence rates for all patients with cancer and survivors and should be included as standard of care to ensure the best possible cancer treatment outcomes.

RESUMO

Smoking prevalence among individuals with mental and behavioral health needs is considerably higher compared to the general population, but evidence-based smoking cessation therapies are underutilized in mental and behavioral healthcare settings, despite the fact that these treatments are both safe and effective. The goal of this paper is to present the background, design and pilot of Project TEACH (Tobacco Education and Cessation in the Health System) developed to improve clinical practice by offering specialized training in the provision of smoking cessation interventions to care providers in community mental health centers in Texas. This is achieved through engaging the expertise of clinicians at the MD Anderson Cancer Center's Tobacco Treatment Program and disseminating this expertise to care providers by means of a novel tele-mentoring approach called Project ECHO (Extension for Community Healthcare Outcomes). Evaluation of our pilot ECHO training project demonstrated that the training was very well received and resulted in self-reported enhancement of the providers' professional practice. This is the first project to extend the collaborative ECHO model to train healthcare providers in smoking cessation. This approach has potential to reduce smoking rates among smokers with mental and behavioral health needs, and consequently contribute to the prevention of cancer and other chronic diseases in this vulnerable population.

RESUMO

Lung cancer is the leading cause of cancer-related death in the United States (U.S.) and is the second most common non-skin cancer among men and women, accounting for about 30% of cancer-related deaths. There is clear and accumulating evidence that continued tobacco use has multiple adverse effects on cancer treatment outcomes, including greater probability of recurrence, second primary malignancies, reduced survival, greater symptom burden, and poorer quality of life (QOL). Recent findings suggest an avenue to significantly mitigate the impact of smoking on lung cancer mortality rates through the use of low-dose computed tomography (LDCT) lung cancer screening. Based on the reviewed evidence (type B), the U.S. Preventive Services Task Force (USPSTF) guidelines of 2015 recommend screening combined with smoking cessation interventions for high-risk heavy smokers and recent quitters. These practice changes offer opportunities to develop novel smoking cessation strategies tailored to highly specific settings that aim to amplify the survivorship gains expected from screening alone. However, there is a paucity of research and data that speaks to the feasibility and efficacy of providing smoking cessation treatment specifically within the context of the LDCT lung cancer screening environment. While some studies have attempted to characterize the parameters within which smoking cessation interventions should be implemented in this context, further research is needed to explore relevant factors such as the format, components, and timing of interventions, as well as the influence of risk perceptions and results of the screening itself on motivation and ability to quit smoking.

RESUMO

PURPOSE/BACKGROUND: It is unclear whether increasing the dose of varenicline beyond the standard dose of 2 mg/d would improve smoking abstinence. METHODS: We examined the effect of 3 mg/d of varenicline on smoking abstinence among smokers who had reduced their smoking by 50% or more in response to 2 mg/d for at least 6 weeks but had not quit smoking. Of 2833 patients treated with varenicline, dosage of a subset of 73 smokers was increased to 3 mg/d after 6 weeks. We used a propensity score analysis involving multiple baseline covariates to create a comparative sample of 356 smokers who remained on 2 mg/d. All smokers received concurrent and similar smoking-cessation counseling. RESULTS: At 3 months, we found higher 7-day point prevalence smoking-abstinence rate in the 3-mg group (26%) than in the 2-mg group (11.5%, χ = 10.60, P < 0.001; risk ratio [RR], 2.3; 95% confidence interval [CI], 1.4-3.6). The difference in abstinence rates remained significant at the 6-month (P < 0.001; RR, 2.6; 95% CI, 1.6-3.9) and 9-month follow-up (P < 0.001; RR, 2.2; 95% CI, 1.4-3.3). CONCLUSIONS: A relatively small increase in the daily dose of varenicline seems to offer a benefit for those who are not able to achieve total abstinence after approximately 6 weeks of 2 mg/d.

RESUMO

BACKGROUND: Weight loss interventions have been successfully delivered via several modalities, but recent research has focused on more disseminable and sustainable means such as telephone- or Internet-based platforms. OBJECTIVE: The aim of this study was to compare an Internet-delivered weight loss intervention to a comparable telephone-delivered weight loss intervention. METHODS: This randomized pilot study examined the effects of 6-month telephone- and Internet-delivered social cognitive theory-based weight loss interventions among 37 cancer survivors. Measures of body composition, physical activity, diet, and physical performance were the outcomes of interest. RESULTS: Participants in the telephone intervention (n=13) showed greater decreases in waist circumference (-0.75 cm for telephone vs -0.09 cm for Internet, P=.03) than the Internet condition (n=24), and several other outcomes trended in the same direction. Measures of engagement (eg, number of telephone sessions completed and number of log-ins) suggest differences between groups which may account for the difference in outcomes. CONCLUSIONS: Cancer survivors in the telephone group evidenced better health outcomes than the Internet group. Group differences may be due to higher engagement in the telephone group. Incorporating a telephone-based component into existing weight loss programs for cancer survivors may help enhance the reach of the intervention while minimizing costs. More research is needed on how to combine Internet and telephone weight loss intervention components so as to maximize engagement and outcomes.

RESUMO

Tobacco use is the most common cause of preventable morbidity and mortality in the United States; it accounts for one-third of all cancer deaths and is thought to account for half of preventable cancer deaths. This article describes the Tobacco Treatment Program at a major academic cancer center. Patients and employees may access these services in a number of ways. All current smokers and recent quitters are proactively contacted and invited to participate. Services provided are tailored to the motivational level of individual patients and their immediate medical needs. The treatment pathways we present are based on our experience from the last 10 years in treating more than 5,000 unique patients with around 60,000 patient visits. These pathways include behavioral counseling and pharmacotherapy, including first-line, second-line, and off-label medication use. This article describes the program with the goal of providing guidance and ideas to others who are developing treatment programs and providing treatment to tobacco users.

RESUMO

OBJECTIVE: Little is known about factors associated with smoking cessation in cancer patients. This study examined the impact of panic attacks on smoking abstinence likelihood among cancer patients receiving tobacco cessation treatment. METHOD: The relationship of panic attacks to 7-day point-prevalence abstinence at mid-treatment, end of treatment, and 6-month post-end of treatment were examined among cancer patients (N=2255 patients; 50.1% female; Mage=54.9, SD=11.0) who received counseling and pharmacotherapy for smoking cessation. Panic attack history indexed by two questions from the Patient Health Questionnaire (PHQ). Point-prevalence abstinence was assessed via the Timeline Follow-Back. RESULTS: Cancer patients with a history of panic attacks, (n=493, 21.9%) relative to those without, were less likely to be abstinent at mid-treatment (OR=0.79, CI95%=0.64-0.98) and end of treatment (OR=0.72, CI95%=0.58-0.89). After adjusting for significant covariates, panic attack history remained predictive of decreased abstinence likelihood at end of treatment (OR =0.78, CI95%=0.62-0.99). CONCLUSIONS: Panic attacks may be related to poorer cessation outcome during smoking treatment among cancer patients, and may be usefully assessed and targeted for intervention.

RESUMO

BACKGROUND: Effective, broad-reaching channels are important for the delivery of health behavior interventions in order to meet the needs of the growing population of cancer survivors in the United States. New technology presents opportunities to increase the reach of health behavior change interventions and therefore their overall impact. However, evidence suggests that older adults may be slower in their adoption of these technologies than the general population. Survivors' interest for more traditional channels of delivery (eg, clinic) versus new technology-based channels (eg, smartphones) may depend on a variety of factors, including demographics, current health status, and the behavior requiring intervention. OBJECTIVE: The aim of this study was to determine the factors that predict cancer survivors' interest in new technology-based health behavior intervention modalities versus traditional modalities. METHODS: Surveys were mailed to 1871 survivors of breast, prostate, and colorectal cancer. Participants' demographics, diet and physical activity behaviors, interest in health behavior interventions, and interest in intervention delivery modalities were collected. Using path analysis, we explored the relationship between four intervention modality variables (ie, clinic, telephone, computer, and smartphone) and potential predictors of modality interest. RESULTS: In total, 1053 respondents to the survey (56.3% response rate); 847 provided complete data for this analysis. Delivery channel interest was highest for computer-based interventions (236/847, 27.9% very/extremely interested) and lowest for smartphone-based interventions (73/847, 8.6%), with interest in clinic-based (147/847, 17.3%) and telephone-delivered (143/847, 16.9%) falling in between. Use of other technology platforms, such as Web cameras and social networking sites, was positively predictive of interest in technology-based delivery channels. Older survivors were less likely to report interest in smartphone-based diet interventions. Physical activity, fruit and vegetable consumption, weight status, and age moderated relationships between interest in targeted intervention behavior and modality. CONCLUSIONS: This study identified several predictors of survivor interest in various health behavior intervention delivery modalities. Overall, computer-based interventions were found to be most acceptable, while smartphones were the least. Factors related to survivors' current technology use and health status play a role in their interest for technology-based intervention versus more traditional delivery channels. Future health behavior change research in this population should consider participants' demographic, clinical, and lifestyle characteristics when selecting a delivery channel. Furthermore, current health behavior interventions for older cancer survivors may be best delivered over the Internet. Smartphone interventions may be feasible in the future following further adoption and familiarization by this particular population.
