Smoking Cessation In Cancer Patients Research Articles

Comparing the Fagerström Test and Heaviness of Smoking Index in Predicting Smoking Abstinence in Cancer Patients.

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. 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. 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. 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. 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.

Qualitative evaluation of the implementation and future sustainability of an e-referral system for smoking cessation at a US NCI-designated comprehensive cancer center: lessons learned.

Promoting smoking cessation is recognized as an essential part of cancer care. Moffitt Cancer Center, supported by the National Cancer Institute Cancer Moonshot Cancer Center Cessation Initiative, developed and implemented an opt-out-based automatic electronic health record (EHR)-mediated referral (e-referral) system for Tobacco Quitline services along with options for local group cessation support and an in-house tobacco treatment specialist. This study evaluated barriers and facilitators for implementation of the e-referral system. Steering committee members (N=12) responsible for developing and implementing the new clinical workflow and nurses (N=12) who were expected to use the new e-referral system completed semi-structured interviews. Qualitative thematic content analyses were conducted. Interviewees perceived the e-referral system as an effective strategy for identifying and referring smokers to cessation services. However, barriers were noted including competing demands and perceptions that smoking cessation was a low priority and that some patients were likely to have low motivation to quit smoking. Suggestions to improve future implementation and sustainability included providing regular trainings and e-referral outcome reports and increasing the visibility of the e-referral system within the EHR. Initial implementation of the e-referral system was perceived as successful; however, additional implementation strategies are needed to ensure sustainability at both the clinician and system levels. Recommendations for future modifications include providing regular clinician trainings and developing a fully closed-loop system. Implications for cancer survivors Initial implementation of an e-referral system for smoking cessation for cancer patients revealed opportunities to improve the smoking cessation referral process at cancer centers.

Smoking cessation for cancer patients through the lens of cancer specialists: challenges & solutions

Abstract Background The benefits of smoking cessation (SC) for cancer patients are widely recognised. However, there has been a limited emphasis on SC in this context and it continues to be a challenge for cancer patients. As part of a larger feasibility study aiming to develop a structured SC pathway for cancer patients in Ireland, this qualitative study explored the SC practices, experiences and opinions of oncology healthcare professionals (HCPs). Methods Semi-structured interviews were conducted with 18 HCPs from lung, breast, cervical, head and neck and general oncology, across 4 specialist adult cancer hospitals in Ireland. Interview transcripts were analysed using thematic analysis. Results Four key themes emerged: (1) Frequently ask and advise but infrequently assist: most HCPs ask about smoking and many advise about available supports, but few refer patients to SC services. Where offered, referrals were to hospital SC services and/or nicotine replacement therapy was prescribed; no HCP prescribed varenicline or bupropion. Barriers included lack of time, ill-defined referral pathways and lack of knowledge. (2) Increased willingness but differing ability to quit: most patients were interested in quitting post diagnosis and had varying support needs, linked to cancer stage, social circumstances and stress levels. (3) Need for an integrated or parallel service: all HCPs suggested that a structured and defined referral pathway will facilitate SC. (4) Motivational counselling and pharmacotherapy combination: many HCPs suggested face to face as the best mode of intervention initially, with regular follow ups and ongoing support virtually, started pre-treatment, with an empathetic and empowering approach with provision of both motivational counselling and SC pharmacotherapy. Conclusions Smoking post cancer diagnosis has serious implications for cancer treatment and prognosis but is frequently overlooked. These findings will inform the design of a SC pathway for cancer patients. Key messages • Despite increased willingness to quit, there is inadequate and inconsistent SC support provision for cancer patients. • Tailored SC support should be an integral part of comprehensive cancer care.

Abstract 5817: Exosomal miR-4466 from nicotine-activated neutrophils promotes tumor cell stemness & metabolism in brain metastasis

Abstract Smoking is associated with lung cancer and has a profound impact on tumor immunity. Nicotine, the addictive and non-carcinogenic smoke component, influences various brain cells and the immune system. However, little is known how long-term use of nicotine affects clinical outcomes in patients with brain metastasis. To address this question, we conducted a retrospective analysis of 810 lung cancer patients with smoking history and assessed brain metastasis. We found that lung cancer patients of current smokers have significantly higher brain metastatic incidence compared to the never-smokers. Immune profiling of the brain metastatic lesions among smokers showed predominant infiltration of neutrophils compared to never-smokers. Notably, mice pre-exposed to nicotine showed a significantly increased number of neutrophils in the brains even before implantation of cancer cells (pre-metastatic niche), and their numbers progressively increased during the metastatic stage. Neutrophil depletion during metastatic colonization caused a remarkable decrease in brain metastasis. Furthermore, we found that chronic exposure of nicotine recruited STAT3-activated N2-neutrophils that secreted exosomal miR-4466 in the brain. This pre-metastatic niche promoted stemness and metabolic switching via SKI/SOX2/CPT1A axis in the tumor cells thereby enabling brain metastasis. Importantly, exosomal miR-4466 levels were found to be elevated in serum/urine of cancer-free subjects with a smoking history and promote tumor growth in vivo, suggesting that exosomal miR-4466 may serve as a promising prognostic biomarker for predicting increased risk of metastatic disease among smoker(s). Our findings suggest a novel pro-metastatic role of nicotine-induced N2-neutrophils in the progression of brain metastasis. We also demonstrated that inhibiting nicotine-induced STAT3-mediated neutrophil polarization effectively abrogated brain metastasis in vivo. Our finding for the first time provides compelling evidence related to the mechanism(s) of neutrophil-mediated brain metastasis that arises from nicotine use. Our results also identified a potential prognostic biomarker for the onset of metastasis as a risk-reduction measure in lung cancer patients and implicated the risk of using nicotine gateway for smoking cessation in cancer patients with a smoking history.

Exosomal miR-4466 from nicotine-activated neutrophils promotes tumor cell stemness and metabolism in lung cancer metastasis

Smoking is associated with lung cancer and has a profound impact on tumor immunity. Nicotine, the addictive and non-carcinogenic smoke component, influences various brain cells and the immune system. However, how long-term use of nicotine affects brain metastases is poorly understood. We, therefore, examined the mechanism by which nicotine promotes lung cancer brain metastasis. In this study, we conducted a retrospective analysis of 810 lung cancer patients with smoking history and assessed brain metastasis. We found that current smoker’s lung cancer patients have significantly higher brain metastatic incidence compared to the never smokers. We also found that chronic nicotine exposure recruited STAT3-activated N2-neutrophils within the brain pre-metastatic niche and secreted exosomal miR-4466 which promoted stemness and metabolic switching via SKI/SOX2/CPT1A axis in the tumor cells in the brain thereby enabling metastasis. Importantly, exosomal miR-4466 levels were found to be elevated in serum/urine of cancer-free subjects with a smoking history and promote tumor growth in vivo, suggesting that exosomal miR-4466 may serve as a promising prognostic biomarker for predicting increased risk of metastatic disease among smoker(s). Our findings suggest a novel pro-metastatic role of nicotine-induced N2-neutrophils in the progression of brain metastasis. We also demonstrated that inhibiting nicotine-induced STAT3-mediated neutrophil polarization effectively abrogated brain metastasis in vivo. Our results revealed a novel mechanistic insight on how chronic nicotine exposure contributes to worse clinical outcome of metastatic lung cancer and implicated the risk of using nicotine gateway for smoking cessation in cancer patients.

Longitudinal Electronic Cigarette Use Among Patients Recently Diagnosed With Cancer Enrolled in a Smoking Cessation Trial.

Many cancer patients who smoke report concurrent e-cigarette use. Using a mixed-methods approach, we aimed to (1) describe longitudinal e-cigarette use over 6 months after a cancer diagnosis and (2) assess the association between e-cigarette use and smoking cessation, among cancer patients in a smoking cessation trial. Data were from a 2-site randomized controlled trial of Standard (brief counseling) versus Intensive treatment (sustained counseling plus smoking cessation medication) in individuals who smoke recently diagnosed with cancer. Participants (n = 303) reported e-cigarette use at baseline, 3 months, and 6 months. Biochemically-verified past 7-day cigarette abstinence was collected at 6 months. Qualitative interviews at 6 months explored factors related to e-cigarette use. E-cigarette use prevalence was highest between baseline and 3 months (16%) and declined over time. Participants using e-cigarettes at follow-up had higher baseline cigarette dependence and smoked more heavily. Multivariable analyses found no significant association between follow-up e-cigarette use and 6-month cigarette abstinence. E-cigarette use at follow-up was higher in the Standard versus Intensive treatment group (p = .003 and .001 at 3 and 6 mo, respectively). Smoking cessation and health concerns were primary reasons for using e-cigarettes. Among individuals who smoke recently diagnosed with cancer and enrolled in a smoking cessation intervention trial, e-cigarette use during trial participation was not associated with smoking abstinence. Individuals who chose to use e-cigarettes were less likely to be receiving intensive cessation support as part of the trial. Further studies are needed to evaluate the association between e-cigarette use and smoking cessation in cancer patients. E-cigarette use was not associated with cigarette abstinence at 6 months among adults who smoke recently diagnosed with cancer enrolled in a smoking cessation trial. Individuals with easier access to evidence-based smoking cessation treatment may be less likely to use e-cigarettes.

Has the National Fall in Smoking Rates in Ireland Been Replicated in Cancer Patients? A 5-Year Report.

Smoking among cancer patients leads to poorer outcomes, yet many patients continue smoking. As part of a feasibility study of smoking cessation for cancer patients in Ireland, smoking rates were reviewed. Hospital Inpatient Enquiry (HIPE) data on the smoking status of discharges with a cancer diagnosis (overall, breast, lung, cervical and head and neck cancer) were used (2014–2018). During 2014–2017, current smoking increased for overall (10.5–11.7%) and lung cancer (24.7–27.2%), then decreased to 11.4% and 24.1%, respectively, in 2018. Current smoking increased for cervical during 2014–2018 (11–19.8%) and initially (2014–2016) for head and neck (3–12.7%) cancer, decreasing to 7.6% in 2018; breast cancer was stable at 6 ± 0.6%. These rates are lower than the Irish (23–20%) and European (29% (average)) general population. During 2014–2017, past smoking increased among overall (15.2–21%) and specific cancers, which was lower than the Irish general population (23–28%). Current smoking was highest among 50–59-year-olds (14–16%), which contrasts with the Irish general population (24–35 years at 32–28%). HIPE data are subject to potential duplicate episodes of care and under-documentation of smoking. However, trend analysis is useful, as these limitations should be stable. Rates remain high; therefore, robust documentation and smoking cessation referrals for cancer patients are important.

Smoking cessation after lung cancer diagnosis improves disease prognosis

Abstract: The presented clinical and epidemiological study is the world»s first large prospective study of the effect of smoking cessation after lung cancer (LC) diagnosis on the prognosis. Follow‑up of 517 patients with NSCLC for 7 years in average showed that continued smoking after diagnosis is a serious negative prognostic factor. At the same time smoking cessation improves OS and PFS by 22,6 months and specific cancer mortality by 22,8 months; reduces the risk of all‑cause mortality by 33 %, the risk of progression by 30 % and the risk of specific cancer mortality by 25 %. Almost 60 % of patients in our study continued smoking after diagnosis. Consequently, they had avoidable excess mortality which eventually reduced their life by 2 years.The positive effect of smoking cessation after diagnosis found in our study significantly exceeds the «meaningful benefit» (improvement in median overall survival by 2,5–6 months) for antineoplastic agents proposed by the American Society of Clinical Oncology (ASCO). Moreover, the study suggests that the benefits of smoking cessation after LC diagnosis are at least equal or superior to the significant results obtained in clinical studies of the effectiveness of innovative treatments.We hope that the results of our study will contribute to the inclusion of smoking cessation in clinical guidelines for the treatment of NSCLC and other cancers. The treatment program for cancer patients should include evidence‑based methods of smoking cessation presented in the form of «Clinical Guidelines for Smoking Cessation for Cancer Patients».Treating smoking in cancer patients is cost‑effective for the health care system, especially when compared to other treat‑ments. Conversely, continuing smoking after diagnosis significantly increases treatment costs.The introduction of recommendations on smoking cessation and treatment of nicotine addiction into the practice will improve the overall mortality rate by 30–35 % in more than 60,000 patients annually diagnosed with lung cancer in Russia. The clinical value of this method is obvious, since it has been proven to be highly efficient in improving the life expectancy of patients, and, ultimately, in reducing cancer mortality in Russia.

Repetitive Transcranial Magnetic Stimulation for Tobacco Treatment in Cancer Patients: A Preliminary Report of a One-Week Treatment.

Background Smoking cessation represents a significant opportunity to improve cancer survival rates, reduces the risk of cancer treatment complications, and improves quality of life. However, about half of cancer patients who smoke continue to smoke despite the availability of several treatments. Previous studies demonstrate that repetitive transcranial magnetic stimulation (rTMS) over the left dorsolateral prefrontal cortex (DLPFC) decreases cue craving, reduces cigarette consumption, and increases the quit rate in tobacco use disorder. We investigated whether 5 sessions of rTMS can be safely and efficaciously used for smoking cessation in cancer patients. Methods We enrolled 11 treatment-seeking smokers with cancer (>5 cigarettes per day) in a randomized, double-blind, sham-controlled proof-of-concept study. Participants received 5 daily sessions of active 10 Hz rTMS of the left DLPFC (3000 pulses per session) or sham rTMS and were followed up for 1 month via phone assessments. Main outcomes included reductions in the number of smoked-cigarettes per day (primary) and craving (secondary). Adverse effects were reported daily by participants. Results Seven of 11 participants completed 5 sessions of rTMS over one week. Compared to sham treatment (n = 4), the active rTMS (n = 3) exhibited modest effects overtime on smoking (Cohen's f2 effect size of 0.16) and large effects on cue craving (Cohen′s f2 = 0.40). No serious side effects related to rTMS were reported in the treatment. Conclusions Five sessions of daily rTMS over the left DLPFC might benefit cancer patients who smoke cigarettes. However, further evidence is needed to determine with more certainty its therapeutic effect and adverse effects for cancer patients who smoke cigarettes.

Effect of smoking on survival following Non-Hodgkin Lymphoma in Ireland

Abstract Background Although Ireland has been to the fore in tobacco control, smoking rates are falling slowly. There is a growing body of evidence that smoking cessation improves outcomes following the diagnosis of several cancers. Notwithstanding the adverse outcomes, a significant number of people who have been diagnosed with cancer continue to smoke. The aim of this study was to determine the role of smoking in overall and 5-year survival in patients diagnosed with Non-Hodgkin Lymphoma (NHL) between 1996 to 2016 (inclusive) in Ireland. Methods Data relating to 12,693 patients diagnosed with NHL was obtained from the National Cancer Registry of Ireland. Kaplan Meier survival analysis with log-rank test was conducted to determine the overall and 5-year survival. Multivariate Cox regression adjusted for age and gender was performed. Results Tobacco smoking has a significant influence on survival following NHL (p = 0.001). Young patients and non-smokers had superior 5-year survival at 87.5% and 59% respectively. On univariate analysis, current and ex-smoking were each significantly associated with increased mortality. After adjustment for age and gender, current smoking remained significant with increased mortality risk (HR-1.47, 95% CI = 1.23-1.76). Conclusions Smoking status is significantly associated with survival from NHL. Smoking cessation in cancer patients is a key component in the improvement of survival. Targeted smoking cessation services for cancer patients are needed; research on the best approach is currently being conducted by this research group. Key messages Current smoking impairs survival from Non-Hodgkin lymphoma. Targeted smoking cessation services for cancer patients are required.

Has the national fall in smoking rate in Ireland been replicated in cancer patients? a 5-year report

Abstract Background Population smoking rates are falling in Ireland, however many cancer patients continue smoking post diagnosis, despite its association with poorer treatment and clinical outcomes. As part of a feasibility study of smoking cessation for cancer patients in Ireland, a review of smoking rates in cancer patients was undertaken. Methods The Hospital Inpatient Enquiry system (HIPE), a national database which collects administrative, demographic & clinical data on discharges from public hospitals in Ireland, provided data (2014-2018) on smoking status of adult discharges with a cancer diagnosis (overall, breast, lung, cervical and head & neck (H&N). Smoking trends were compared with Healthy Ireland data (2015-2018), from a national survey for adults on health & wellbeing. Results During 2014-18, current smoking rose for all cancers (10.5%-11.4%), cervical cancer (11%-19.8%) and initially (2014-2016) for H&N (3%-12.7%) and lung (24.7%-27.2%), which dropped to 7.6% and 24% respectively in 2018; breast was stable at 6 ± 0.6%. Rates are lower than the general population (23%-20%). During 2014-17, past smoking rates demonstrated an upward trend among all cancers and specific cancers, with the highest prevalence among lung (30.3-39%) and lowest among breast (7.3-11%); comparative general population data was 23-28%. Current smoking rates for all cancers were highest among 50-59-year-olds (14-16%), which contrasts with the general population (24-35 years at 32-28%). Current and past smoking rates for all cancers were consistently higher among males, similar to the general population. Conclusions HIPE data is limited by duplicate episodes of care, and it is recognised that smoking documentation may be an underestimate. However, it is useful to analyse trends, as these limitations should be stable over the 5-year study period. Rates remain high; our further research will document barriers and facilitators to smoking cessation among cancer patients. Key messages Smoking rates in cancer patients are high despite proven benefits of smoking cessation. Supportive smoking cessation services as part of routine cancer care are indicated.

Examining the effects of problematic alcohol use on cigarette abstinence in recently diagnosed cancer patients enrolled in a cessation trial: A secondary analysis

AimsAmong people with cancer, dual alcohol and tobacco use increases risk for morbidity and mortality. Most smoking cessation clinical trials with this patient population have excluded individuals with problematic alcohol use. This investigation examined whether problematic alcohol use affects smoking cessation in cancer patients. MethodsMixed-methods secondary analysis of data from the Smokefree Support Study, a randomized-controlled trial examining the efficacy of Intensive (IT; n = 153) vs. Standard Treatment (ST; n = 150) for smoking cessation in newly diagnosed cancer patients. Problematic alcohol use was assessed at enrollment using the Cut-Down-Annoyed-Guilty-Eye-Opener (CAGE), weekly frequency of alcohol use and binge drinking measures. Alcohol use was categorized as: no current alcohol use, moderate and problematic use. The primary outcome was biochemically-confirmed cigarette abstinence at 6-months. A subset of patients (n = 72) completed qualitative exit-interviews. ResultsAmong all participants, biochemically-confirmed cigarette abstinence rates were 25% (n = 32), 28% (n = 27), and 36% (n = 20) for participants reporting no current alcohol use, moderate use, and problematic use, respectively (p = 0.33). In logistic regression analysis, neither problematic alcohol use (AOR = 0.96, 95% CI = 0.35–2.67, p = .94) nor the problematic use by study arm interaction (AOR = 2.22, 95% CI = 0.59–8.39, p = .24) were associated with biochemically-confirmed 6-month abstinence. Qualitatively, participants reported that drinking alcohol triggers urges to smoke. ConclusionNewly diagnosed cancer patients reporting problematic alcohol use were not less likely to quit smoking than those without. Additional research is needed to investigate whether problematic alcohol users may benefit from smoking and alcohol behavior change interventions at the time of cancer diagnosis.

Canada's Progress to Make Smoking Cessation a First-Line Cancer Treatment

Background: Evidence indicates that smoking cessation improves the effectiveness of treatment and likelihood of survival among all cancer patients, not just those with tobacco-related disease, yet smoking is rarely addressed in oncology practice. Prior to 2016, only 3 provinces in Canada (out of a total of 10 provinces and three territories) reported implementation of smoking cessation for ambulatory cancer patients. Aim: Based on this evidence, the Canadian Partnership Against Cancer (CPAC) implemented a systems change initiative to promote adoption of evidence-based smoking cessation within provincial and territorial cancer systems across Canada. Methods: In 2016, CPAC funded seven provinces and two territories over a 15-month period to plan, implement or evaluate integration of evidence-based smoking cessation for ambulatory cancer patients within cancer systems. Funds were used to plan (2 provinces and 2 territories), implement (3 provinces) or evaluate (2 provinces) systematic, evidence-based approaches to smoking cessation within ambulatory cancer care settings (e.g., establishing routine systems for identification of smoking cancer patients and system to support patients to quit). Funds could not be used for direct service delivery (e.g., cessation counseling). Results: After 15-months of funding from CPAC, 6 provinces reported implementation of smoking cessation for ambulatory cancer patients. The remaining province and 2 territories funded by CPAC reported development of plans for adoption of smoking cessation for cancer patients in the future. Within provinces reporting implementation of smoking cessation for cancer patients, between 65%-97% of ambulatory cancer patients were screened for smoking status; 22%-80% of these patients were offered a referral to cessation services, and 21%-45% of cancer patients accepted a referral. Conclusion: Despite provincial and territorial variations in readiness to uptake evidence-based smoking cessation for cancer patients, CPAC's approach has led to substantial progress in adoption of this approach across Canada. While progress has been made, adoption of smoking cessation and relapse prevention by cancer systems is not yet widespread in Canada. Scale-up to remaining provinces and territory, and spread within existing provinces and territories is required to reach all cancer patients and families who require support to quit smoking. Framing smoking cessation as a therapeutic intervention, not prevention, and a routine part of cancer treatment will be critical for sustainability of this work.

Lessons learned implementing a province-wide smoking cessation initiative in Ontario’s cancer centres

Purpose A large body of evidence clearly shows that cancer patients experience significant health benefits with smoking cessation. Cancer Care Ontario, the provincial agency responsible for the quality of cancer services in Ontario, has undertaken a province-wide smoking cessation initiative. The strategies used, the results achieved, and the lessons learned are the subject of the present article.Methods Evidence related to the health benefits of smoking cessation in cancer patients was reviewed. A steering committee developed a vision statement for the initiative, created a framework for implementation, and made recommendations for the key elements of the initiative and for smoking cessation best practices.Results New ambulatory cancer patients are being screened for their smoking status in each of Ontario’s 14 regional cancer centres. Current or recent smokers are advised of the benefits of cessation and are directed to smoking cessation resources as appropriate. Performance metrics are captured and used to drive improvement through quarterly performance reviews and provincial rankings of the regional cancer centres.Conclusions Regional smoking cessation champions, commitment from Cancer Care Ontario senior leadership, a provincial secretariat, and guidance from smoking cessation experts have been important enablers of early success. Data capture has been difficult because of the variety of information systems in use and non-standardized administrative and clinical processes. Numerous challenges remain, including increasing physician engagement; obtaining funding for key program elements, including in-house resources to support smoking cessation; and overcoming financial barriers to access nicotine replacement therapy. Future efforts will focus on standardizing processes to the extent possible, while tailoring the approaches to the populations served and the resources available within the individual regional cancer programs.
