Crit Rev Oncol Hematol 2024; 196:104323. [PMID: 38462148 DOI: 10.1016/j.critrevonc.2024.104323] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2023] [Revised: 02/11/2024] [Accepted: 03/06/2024] [Indexed: 03/12/2024] Open
Abstract
BACKGROUND Smoking history is a heterogeneous situation for different populations, and numerous studies suggest that smoking cessation is conducive to reduce the mortality of lung cancer. However, no quantitative meta-analysis regarding smoking cessation duration based on different populations has demonstrated it clearly. METHODS We systematically searched four electronic databases (PubMed, Embase, the Cochrane Central Register of Controlled Trials, and Scoups) till February 2023. Eligible studies reported the association between lung cancer survival and duration of smoking cessation. Additionally, we stratified the study population according to whether they had lung cancer at the time they quit smoking. Studies were pooled with the random-effects model. RESULTS Out of the 11,361 potential studies initially identified, we included 24 studies involving 969,560 individuals in our analysis. Lung cancer mortality varied across two groups: general quitters and peri-diagnosis quitters. For general quitters, those who had quit smoking for less than 10 years exhibited an RR of 0.64 (95% CI [0.55-0.76]), while those who quit for 10-20 years had an RR of 0.33 (0.25-0.43), over 20 years had an RR of 0.16 (0.11-0.24), and never-smokers had an RR at 0.11 (0.07-0.15). Among peri-diagnosis quitters, the 1-year Overall Survival (OS) showed an RR of 0.80 (0.67-0.96), the 2-year OS had an RR of 0.89 (0.80-0.98), the 3-year OS had an RR of 0.93 (0.84-1.03), and the 5-year OS had an RR of 0.85 (0.76-0.96). CONCLUSIONS Earlier and longer smoking cessation is associated with reduced lung cancer mortality, no matter in which cessation stage for two different populations.

Screening for lung cancer: 2023 guideline update from the American Cancer Society. CA Cancer J Clin 2024; 74:50-81.

Abstract
Lung cancer is the leading cause of mortality and person-years of life lost from cancer among US men and women. Early detection has been shown to be associated with reduced lung cancer mortality. Our objective was to update the American Cancer Society (ACS) 2013 lung cancer screening (LCS) guideline for adults at high risk for lung cancer. The guideline is intended to provide guidance for screening to health care providers and their patients who are at high risk for lung cancer due to a history of smoking. The ACS Guideline Development Group (GDG) utilized a systematic review of the LCS literature commissioned for the US Preventive Services Task Force 2021 LCS recommendation update; a second systematic review of lung cancer risk associated with years since quitting smoking (YSQ); literature published since 2021; two Cancer Intervention and Surveillance Modeling Network-validated lung cancer models to assess the benefits and harms of screening; an epidemiologic and modeling analysis examining the effect of YSQ and aging on lung cancer risk; and an updated analysis of benefit-to-radiation-risk ratios from LCS and follow-up examinations. The GDG also examined disease burden data from the National Cancer Institute's Surveillance, Epidemiology, and End Results program. Formulation of recommendations was based on the quality of the evidence and judgment (incorporating values and preferences) about the balance of benefits and harms. The GDG judged that the overall evidence was moderate and sufficient to support a strong recommendation for screening individuals who meet the eligibility criteria. LCS in men and women aged 50-80 years is associated with a reduction in lung cancer deaths across a range of study designs, and inferential evidence supports LCS for men and women older than 80 years who are in good health. The ACS recommends annual LCS with low-dose computed tomography for asymptomatic individuals aged 50-80 years who currently smoke or formerly smoked and have a ≥20 pack-year smoking history (strong recommendation, moderate quality of evidence). Before the decision is made to initiate LCS, individuals should engage in a shared decision-making discussion with a qualified health professional. For individuals who formerly smoked, the number of YSQ is not an eligibility criterion to begin or to stop screening. Individuals who currently smoke should receive counseling to quit and be connected to cessation resources. Individuals with comorbid conditions that substantially limit life expectancy should not be screened. These recommendations should be considered by health care providers and adults at high risk for lung cancer in discussions about LCS. If fully implemented, these recommendations have a high likelihood of significantly reducing death and suffering from lung cancer in the United States.

CA Cancer J Clin 2024; 74:84-114. [PMID: 37909870 DOI: 10.3322/caac.21808] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Revised: 07/20/2023] [Accepted: 07/21/2023] [Indexed: 11/03/2023] Open
Abstract
Current US lung cancer screening recommendations limit eligibility to adults with a pack-year (PY) history of ≥20 years and the first 15 years since quit (YSQ). The authors conducted a systematic review to better understand lung cancer incidence, risk and mortality among otherwise eligible individuals in this population beyond 15 YSQ. The PubMed and Scopus databases were searched through February 14, 2023, and relevant articles were searched by hand. Included studies examined the relationship between adults with both a ≥20-PY history and ≥15 YSQ and lung cancer diagnosis, mortality, and screening ineligibility. One investigator abstracted data and a second confirmed. Two investigators independently assessed study quality and certainty of evidence (COE) and resolved discordance through consensus. From 2636 titles, 22 studies in 26 articles were included. Three studies provided low COE of elevated lung cancer incidence beyond 15 YSQ, as compared with people who never smoked, and six studies provided moderate COE that the risk of a lung cancer diagnosis after 15 YSQ declines gradually, but with no clinically significant difference just before and after 15 YSQ. Studies examining lung cancer-related disparities suggest that outcomes after 15 YSQ were similar between African American/Black and White participants; increasing YSQ would expand eligibility for African American/Black individuals, but for a significantly larger proportion of White individuals. The authors observed that the risk of lung cancer not only persists beyond 15 YSQ but that, compared with individuals who never smoked, the risk may remain significantly elevated for 2 or 3 decades. Future research of nationally representative samples with consistent reporting across studies is needed, as are better data from which to examine the effects on health disparities across different populations.

Abstract
BACKGROUND The association between duration of smoking abstinence before non-small-cell lung cancer (NSCLC) diagnosis and subsequent survival can influence public health messaging delivered in lung-cancer screening. We aimed to assess whether the duration of smoking abstinence before diagnosis of NSCLC is associated with improved survival. METHODS In this retrospective, pooled analysis of cohort studies, we used 26 cohorts participating in Clinical Outcomes Studies of the International Lung Cancer Consortium (COS-ILCCO) at 23 hospitals. 16 (62%) were from North America, six (23%) were from Europe, three (12%) were from Asia, and one (4%) was from South America. Patients enrolled were diagnosed between June 1, 1983, and Dec 31, 2019. Eligible patients had smoking data before NSCLC diagnosis, epidemiological data at diagnosis (obtained largely from patient questionnaires), and clinical information (retrieved from medical records). Kaplan-Meier curves and multivariable Cox models (ie, adjusted hazard ratios [aHRs]) were generated with individual, harmonised patient data from the consortium database. We estimated overall survival for all causes, measured in years from diagnosis date until the date of the last follow-up or death due to any cause and NSCLC-specific survival. FINDINGS Of 42 087 patients with NSCLC in the COS-ILCCO database, 21 893 (52·0%) of whom were male and 20 194 (48·0%) of whom were female, we excluded 4474 (10·6%) with missing data. Compared with current smokers (15 036 [40·0%] of 37 613), patients with 1-3 years of smoking abstinence before NSCLC diagnosis (2890 [7·7%]) had an overall survival aHR of 0·92 (95% CI 0·87-0·97), patients with 3-5 years of smoking abstinence (1114 [3·0%]) had an overall survival aHR of 0·90 (0·83-0·97), and patients with more than 5 years of smoking abstinence (10 841 [28·8%]) had an overall survival aHR of 0·90 (0·87-0·93). Improved NSCLC-specific survival was observed in 4301 (44%) of 9727 patients who had quit cigarette smoking and was significant at abstinence durations of more than 5 years (aHR 0·87, 95% CI 0·81-0·93). Results were consistent across age, sex, histology, and disease-stage distributions. INTERPRETATION In this large, pooled analysis of cohort studies across Asia, Europe, North America, and South America, overall survival was improved in patients with NSCLC whose duration of smoking abstinence before diagnosis was as short as 1 year. These findings suggest that quitting smoking can improve overall survival, even if NSCLC is diagnosed at a later lung-cancer screening visit. These findings also support the implementation of public health smoking cessation strategies at any time.

Abstract
BackgroundSmoking is associated with increased mortality in patients with cancer. However, there are limited data on the impact of smoking on the survival of patients with brain metastases. Therefore, this study aimed to evaluate whether smoking was associated with survival and whether smoking cessation was beneficial to these patients.MethodsThis study used lung cancer with a brain metastasis cohort of the West China Hospital of Sichuan University from 2013 to 2021. Patients were stratified according to smoking history; the distribution, clinical characteristics, and survival data of each group were estimated. Kaplan-Meier analysis and risk analysis were performed for the survival endpoint.ResultsOf the 2,647 patients included in the analysis, the median age was 57.8 years, and 55.4% were men. Among them, 67.1% had no smoking history, 18.9% still smoked, and 14% reported quitting smoking. Compared with never smokers, current smokers [HR, 1.51 (95% CI, 1.35-1.69), p < 0.01] and former smokers [HR, 1.32 (95% CI, 1.16-1.49), p<0.01] had an increased risk of death. However, quitting smoking was not associated with improved survival [HR, 0.90 (95% CI, 0.77-1.04), p = 0.16]. The overall survival increased with the increase of smoking cessation years.ConclusionsIn lung cancer patients with brain metastases, smoking was associated with an increased risk of death, but quitting smoking was not associated with improved survival.

Evaluating the impact of culturally specific patient-centric behavioral intervention package versus usual care for tobacco cessation among patients attending noncommunicable disease clinics in North India: A single-blind trial pilot study protocol. Tob Use Insights 2022; 14:1179173X211056622. [PMID: 34987297 PMCID: PMC8721367 DOI: 10.1177/1179173x211056622] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2020] [Accepted: 10/08/2020] [Indexed: 11/30/2022] Open
Abstract
Background In a low and middle-income country (LMIC) like India, non—communicable diseases (NCDs) contribute a major proportion (61.8%) of all causes of death. Out of this, 48% of cardiovascular diseases , 23% of Chronic Respiratory Diseases , and 10% of Cancer deaths are attributable to tobacco use. Tobacco use is a major risk factor for NCDs and thus, the tobacco cessation approach is a high priority intervention to combat complications and death among NCD patients. While several interventions are available for tobacco cessation, in resource constraint countries like India, the effectiveness of low-cost, culturally specific patient-centric tobacco cessation behavioral intervention holds a potential that needs to be evaluated. A newly developed evidence-based tobacco cessation intervention package will be compared with the existing/usual care provided under the National Programme for Prevention and Control of Cancers, Diabetes, Cardiovascular Diseases, and Stroke (NPCDCS) at NCD clinics. Methods and design 2 arm, parallel-group randomized controlled trial. Participants Patients aged ≥30 years suffering from NCD, currently using tobacco, and attending NCD clinics in 2 districts of Punjab, India. Sample size A total of 200 participants meeting the selection criteria will be recruited. They will be allocated either to the intervention arm or control (usual care) arm (100 each) using block randomization. Intervention For the participants, there will be 4 face-to-face disease-specific cessation counseling sessions, disease-specific pamphlets, short text messages in vernacular language, that is, Punjabi. Follow-ups will be done at the third, sixth, ninth, and 12th months. Primary outcome Seven-day abstinence, biochemically verified by plasma cotinine levels. Secondary outcome Quit attempts, number of sticks/number of times of smokeless tobacco usage in a day, and stage of behavior change in tobacco users. Discussion This multicomponent culturally specific-patient-centric behavioral intervention package for tobacco cessation at NCD clinic settings focusing on the individual, family, and social environment could increase the outreach of cessation services using existing resources, thereby strengthening health systems and enhancing the quality of life of NCD patients. Trial registration The protocol for the study has been registered with the Clinical Trials Registry in India under the registration number CTRI/2018/01/011643.

Abstract
Comprehensive studies on cancer patients with different smoking histories, including non-smokers, former smokers, and current smokers, remain elusive. Therefore, we conducted a multi-omics analysis to explore the effect of smoking history on cancer patients. Patients with smoking history were screened from The Cancer Genome Atlas database, and their multi-omics data and clinical information were downloaded. A total of 2,317 patients were included in this study, whereby current smokers presented the worst prognosis, followed by former smokers, while non-smokers showed the best prognosis. More importantly, smoking history was an independent prognosis factor. Patients with different smoking histories exhibited different immune content, and former smokers had the highest immune cells and tumor immune microenvironment. Smokers are under a higher incidence of genomic instability that can be reversed following smoking cessation in some changes. We also noted that smoking reduced the sensitivity of patients to chemotherapeutic drugs, whereas smoking cessation can reverse the situation. Competing endogenous RNA network revealed that mir-193b-3p, mir-301b, mir-205-5p, mir-132-3p, mir-212-3p, mir-1271-5p, and mir-137 may contribute significantly in tobacco-mediated tumor formation. We identified 11 methylation driver genes (including EIF5A2, GBP6, HGD, HS6ST1, ITGA5, NR2F2, PLS1, PPP1R18, PTHLH, SLC6A15, and YEATS2), and methylation modifications of some of these genes have not been reported to be associated with tumors. We constructed a 46-gene model that predicted overall survival with good predictive power. We next drew nomograms of each cancer type. Interestingly, calibration diagrams and concordance indexes are verified that the nomograms were highly accurate for the prognosis of patients. Meanwhile, we found that the 46-gene model has good applicability to the overall survival as well as to disease-specific survival and progression-free intervals. The results of this research provide new and valuable insights for the diagnosis, treatment, and follow-up of cancer patients with different smoking histories.

Abstract
Pulmonary function testing remains the central determinant of candidacy for pulmonary resection and indicator of perioperative risk. For patients with borderline pulmonary function, exercise testing can help determine surgical candidacy either via stair climbing or by obtaining a maximum oxygen consumption. The Thoracic Revised Cardiac Risk Index should be used to select patients for further cardiac testing. Patient comorbidities, medications, functional limitations, and smoking status are also requisite assessments of the preoperative evaluation that influence perioperative outcomes. A minimally invasive approach to pulmonary resection reduces perioperative risk and may be of most benefit to patients with borderline pulmonary function.

Abstract
INTRODUCTION To evaluate the need for tobacco cessation services within a multidisciplinary clinic (MDC), we surveyed patients on their smoking status, interest in quitting, and willingness to participate in a clinic-based cessation program. We further evaluated the association between interest in cessation or willingness to participate in a cessation program and overall survival (OS). METHODS From 2014 to 2019, all new patients with lung cancer in the MDC at Baptist Cancer Center (Memphis, TN) were administered a social history questionnaire to evaluate their demographic characteristics, smoking status, tobacco dependence, interest in quitting, and willingness to participate in a cessation program. We used chi-square tests and logistic regression to compare characteristics of those who would participate to those who would not or were unsure and Kaplan-Meier curves and Cox regression to evaluate the association between cessation interest or willingness to quit and OS. RESULTS Of 641 total respondents, the average age was 69 years (range: 32-95), 47% were men, 64% white, 34% black, and 17% college graduates. A total of 90% had ever smoked: 34% currently and 25% quit within the past year. Among the current smokers, 60% were very interested in quitting and 37% would participate in a cessation program. Willingness to participate in a cessation program was associated with greater interest in quitting (p < 0.0001), better OS (p = 0.02), and reduced hazard of death (hazard ratio = 0.52, 95% confidence interval: 0.30-0.88), but no other characteristics. CONCLUSIONS Patients with lung cancer in an MDC expressed considerable interest in tobacco cessation services; patients willing to participate in a clinic-based cessation program had improved survival.

Abstract
Background Smoking can cause non-small cell lung cancer (NSCLC). However, the effects of preoperative smoking on tumor progression are not well-known. In addition, the duration of smoking cessation that can provide NSCLC patients with smoking history similar postoperative prognosis as that of nonsmokers remains unknown. This study aimed to investigate the period of smoking cessation that may “compensate” for past smoking history regarding postoperative survival in cases of resected pathological stage I NSCLC by examining the relationship between clinicopathological factors and preoperative smoking. Methods We retrospectively examined clinicopathological factors including preoperative smoking status and postoperative survival in 453 patients with pathologically proven stage I NSCLC at our Institute. Smoking status was evaluated using the following four parameters: cigarettes per day, number of years of smoking, pack-years, and number of years since smoking cessation. Results Pathological factors that reflect tumor invasiveness including vascular invasion (VI) and pleural invasion (PL) were associated with the degree of preoperative smoking in adenocarcinomas, particularly invasive diameters of 2–3 cm. Such a relationship was not identified for non-adenocarcinomas. Heavy smoking status was significantly related to PL in lepidic or papillary predominant adenocarcinomas and to VI in acinar or solid predominant adenocarcinomas. Former smokers who quit smoking for ≥10 years had similar postoperative survival as non-smokers for adenocarcinoma ≤3 cm. Conclusions Accumulative smoking habit correlated with VI and PL, particularly in 2–3 cm adenocarcinoma, whereas larger adenocarcinomas and non-adenocarcinomas of any size appear to grow and become invasive independent of preoperative smoking status. Longer smoking cessation ≥10 years can result in postoperative survival similar to that of non-smokers with adenocarcinomas ≤3 cm. Current smokers should quit smoking immediately to ensure longer survival even though they suffer from small-sized lung adenocarcinomas in the future.

Abstract
BACKGROUND Lung cancer patients who continue to smoke after diagnosis are at increased risk of treatment toxicity, residual/recurrent disease, future malignancies, and all-cause mortality. Guidelines including those from National Comprehensive Cancer Network and Cancer Care Ontario advocate for screening, counseling, and access to smoking cessation services for all cancer patients; however, barriers from both patient and health care professional (HCP) perspectives contribute to lack of implementation. OBJECTIVE The objective of this study was to identify the different perspectives among patients and HCPs in how the promotion of person-centred approaches may be used when offering smoking cessation services to patients who are receiving care within a regional cancer centre. METHODS Qualitative data were generated using various methods, including focus groups with HCPs and interviews with patients. In total, 16 HCPs participated in three focus groups: including nine radiation therapists, five registered nurses, one registered dietitian, and one physiotherapist. Of 55 patients accrued, 19 were interviewed. Both focus groups and interviews were audio recorded, and the recordings were transcribed verbatim. Transcripts were then analyzed using narrative thematic analysis to define and identify themes. RESULTS The identified themes were categorized into three topic areas: knowledge (eg, impact of smoking on illness and why they should not smoke); individual decision to quit (eg, motivators), and the social unacceptability of smoking (eg, the public perception of smoking over the last 40 years). HCP-identified themes included identification of smokers, triggers to start a conversation, approach, gaps and barriers to cessation, rationale for cessation, and judgment. Patient-identified themes included knowledge, individual decision to quit, and the social unacceptability of smoking. CONCLUSION Understanding patient and HCP perspectives on smoking cessation will help influence practice to ensure that patients are not judged, assumptions are not made, and individualized and person-centred care is provided. HCP awareness of these themes and the patient perspective may challenge assumptions and values.

Abstract
INTRODUCTION The purpose of this study was to explore the association of smoking status and clinically relevant duration of smoking cessation with long-term survival after lung cancer (LC) or colorectal cancer (CRC) diagnosis. We compared survival of patients with LC and CRC who were never-smokers, long-term, medium-term, and short-term quitters, and current smokers around diagnosis. METHODS We studied 5575 patients in Cancer Care Outcomes Research and Surveillance (CanCORS), a national, prospective observational cohort study, who provided smoking status information approximately 5 months after LC or CRC diagnosis. Smoking status was categorized as: never-smoker, quit >5 years prior to diagnosis, quit between 1-5 years prior to diagnosis, quit less than 1 year before diagnosis, and current smoker. We examined the relationship between smoking status around diagnosis with mortality using Cox regression models. RESULTS Among participants with LC, never-smokers had lower mortality risk compared with current smokers (HR 0.71, 95% CI 0.57 to 0.89). Among participants with CRC, never-smokers had a lower mortality risk as compared to current smokers (HR 0.79, 95% CI 0.64 to 0.99). CONCLUSIONS Among both LC and CRC patients, current smokers at diagnosis have higher mortality than never-smokers. This effect should be further studied in the context of tumor biology. However, smoking cessation around the time of diagnosis did not affect survival in this sample. IMPLICATIONS The results from our analysis of patients in the CanCORS consortium, a large, geographically diverse cohort, show that both LC and CRC patients who were actively smoking at diagnosis have worse survival as compared to never-smokers. While current smoking is detrimental to survival, cessation upon diagnosis may not mitigate this risk.

Abstract
Objective: To evaluate the impact of current versus former smoking status on the outcomes of non-metastatic non-small cell lung cancer (NSCLC) treated with upfront surgery. Methods: This is a post-hoc analysis of patients diagnosed with NSCLC, stage I-III within the National Lung Screening Trial (NLST). Kaplan-Meier analysis was used to delineate the impact of smoking status on overall survival. Moreover, Cox regression analyses were utilized to assess factors predicting overall and lung cancer-specific survival. Results: A total of 773 patients were included in the current study. Former smokers (at the time of randomization of the NLST study) were 338 patients while current smokers were 435 patients. For overall survival, former smokers have better outcomes compared to current smokers (P = 0.023). Within multivariate Cox regression analysis, the following factors were predictive of worse overall survival: older age (P = 0.037), male gender (P = 0.022), current smoking (P = 0.022), advanced stage (P < 0.001) and preexisting stroke (P = 0.015). Likewise, the following factors were predictive of worse lung cancer-specific survival in multivariate Cox regression analysis: current smoking (P = 0.009) and advanced stage (P < 0.001). Conclusions: Among patients with early-stage NSCLC treated with upfront surgery, current smokers have worse overall and lung cancer-specific survival compared to former smokers. Expert opinion: Among patients with non-metastatic NSCLC treated with upfront surgical resection, current smokers have worse overall, lung cancer-specific and progression-free survival compared to former smokers. Smoking cessation counseling should be incorporated into management strategies of early stage NSCLC.

Abstract
Background: The Global Initiative for Chronic Obstructive Lung Disease (GOLD) released an updated document in 2017 that excluded the spirometric parameter in the classification of patients. The validity of this new classification system in predicting mortality and respiratory hospitalization is still uncertain. Methods: Outpatients (n=149) with chronic obstructive pulmonary disease (COPD) who underwent spirometry and six-minutes walking test from October 2011 to September 2013 were enrolled. The overall mortality and rate of respiratory hospitalization over a median of 61 months were analyzed. Kaplan-Meier survival analyses, receiver operaing curve analyses with areas under the curve (AUCs), and logistic regression analyses for GOLD 2007, GOLD 2011, GOLD 2017, and/or BODE index were performed to evaluate their abilities to predict mortality and respiratory hospitalization. Results: Forty-two (53.2%) patients in 2011 GOLD C or D group were categorized into 2017 GOLD A or B group. The odds ratios of GOLD 2017 group C and group D relative to group A were 7.55 (95% CI, 1.25-45.8) and 25.0 (95% CI, 6.01-102.9) for respiratory hospitalization. Patients in GOLD 2017 group A and group B had significantly better survival (log-rank test, p<0.001) compared with patients in group D; however, survival among patients in GOLD 2007 groups and GOLD 2011 groups was comparable. The AUC values for GOLD 2007, GOLD 2011, GOLD 2017, and BODE index were 0.573, 0.624, 0.691, 0.692 for mortality (p=0.013) and 0.697, 0.707, 0.741, and 0.754 for respiratory hospitalization (p=0.296), respectively. Conclusion: The new GOLD classification may perform better than the previous classifications in terms of predicting mortality and respiratory hospitalization.

Abstract
Background Continued smoking in cancer patients undergoing treatment results in significantly higher rates of treatment toxicities and persistent effects, increased risk of recurrence and second malignancy, and increased all-cause mortality. Despite this, routine tobacco use screening and the provision of smoking cessation treatment has yet to be implemented widely in the cancer setting. Objective The objective of this study was to implement and evaluate the adoption and impact of an innovative Smoking Cessation e-referral System (CEASE) to promote referrals to smoking cessation programs in cancer patients. Methods A patient-directed electronic smoking cessation platform (CEASE) was developed to promote smoking screening and referral and implemented at 1 of Canada’s largest cancer centers. The implementation and evaluation were guided by the Ottawa Model of Research Use. An interrupted time series design was used to examine the impact of CEASE on screening rates, referrals offered, and referrals accepted compared with a previous paper-based screening program. A subsample of smokers or recent quitters was also assessed and compared pre- and postimplementation to examine the effect of CEASE on subsequent contact with smoking cessation programs and quit attempts. Results A total of 17,842 new patients attended clinics over the 20-month study period. The CEASE platform was successfully implemented across all disease sites. Screening rates increased from 44.28% (2366/5343) using the paper-based approach to 65.72% (3538/5383) using CEASE (P<.01), and referrals offered to smokers who indicated interest in quitting increased from 18.6% (58/311) to 98.8% (421/426; P<.01). Accepted referrals decreased from 41% (24/58) to 20.4% (86/421), though the overall proportion of referrals generated from total current/recent tobacco users willing to quit increased from 5.8% (24/414) to 20.2% (86/426) due to the increase in referrals offered. At 1-month postscreening, there was no significant difference in the proportion that was currently using tobacco and had not changed use in the past 4 weeks (pre: 28.9% [24/83] and post: 28.8% [83/288]). However, contact with the referral program increased from 0% to 78% in the postCEASE cohort (P<.001). Conclusions CEASE is an innovative tool to improve smoking screening and can be implemented in both a time- and cost-effective manner which promotes sustainability. CEASE was successfully implemented across all clinics and resulted in improvements in overall screening and referral rates and engagement with referral services.

Abstract
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.

Abstract
This randomized controlled trial aimed to examine the effectiveness of a smoking cessation intervention using a risk communication approach. A total of 528 smoking cancer patients were randomly allocated either into an intervention group (n = 268) to receive brief advice based on risk communication by a nurse counselor or a control group (n = 260) to receive standard care. Subjects in both groups received a smoking cessation booklet. Patient follow-ups were at 1 week and at 1, 3, 6, 9 and 12 months. No significant differences were found in self-reported point-prevalence 7-day abstinence between the intervention and control groups at 6 months (15.7% vs 16.5%; OR 0.94, 95% CI 0.59-1.50). The rate of at least 50% self-reported reduction of smoking at 6 months, was higher in the intervention group than in the control group (16.8% vs 12.3%; OR 1.43, 95% CI 0.88-2.35). The biochemically validated quit rate at the 6-month follow-up was higher in the intervention group than in the control group (5.2% vs 3.8%; OR 1.38, 95% CI 0.60-3.16). These data suggest that advice based on risk communication was not effective for quitting but improved the rate of smoking reduction among smoking cancer patients.

Abstract
RATIONALE Smoking is the largest contributor to lung cancer risk, and those who continue to smoke after diagnosis have a worse survival. Screening for lung cancer with low-dose computed tomography (LDCT) reduces mortality in high-risk individuals. Smoking cessation is an essential component of a high-quality screening program. OBJECTIVES To quantify the effects of smoking history and abstinence on mortality in high-risk individuals who participated in the NLST (National Lung Screening Trial). METHODS This is a secondary analysis of a randomized controlled trial (NLST). MEASUREMENTS AND MAIN RESULTS Measurements included self-reported demographics, medical and smoking history, and lung cancer-specific and all-cause mortality. Cox regression was used to study the association of mortality with smoking status and pack-years. Kaplan-Meier survival curves were examined for differences in survival based on trial arm and smoking status. Current smokers had an increased lung cancer-specific (hazard ratio [HR], 2.14-2.29) and all-cause mortality (HR, 1.79-1.85) compared with former smokers irrespective of screening arm. Former smokers in the control arm abstinent for 7 years had a 20% mortality reduction comparable with the benefit reported with LDCT screening in the NLST. The maximum benefit was seen with the combination of smoking abstinence at 15 years and LDCT screening, which resulted in a 38% reduction in lung cancer-specific mortality (HR, 0.62; 95% confidence interval, 0.51-0.76). CONCLUSIONS Seven years of smoking abstinence reduced lung cancer-specific mortality at a magnitude comparable with LDCT screening. This reduction was greater when abstinence was combined with screening, highlighting the importance of smoking cessation efforts in screening programs.

Abstract
Tobacco smoke contains more than 4000 detectable substances, such as polycyclic aromatic hydrocarbons, nicotine, carbon monoxide and heavy metals, which are considered powerful enzymatic inducers that have notable influence on the efficacy and tolerability of many medications through complex pharmacokinetic and pharmacodynamic interactions. As a result, adjustments of drug dosages are required in smokers, both if they continue to smoke or if they quit after smoking cessation treatment. The purpose of this review is to examine the main drug interactions with tobacco smoke clinically relevant, with a closer look on patients developing oncologic diseases.

Abstract
Approximately 20% of cancer patients smoke at diagnosis (all localizations included), and over two thirds continue despite the therapeutic management of their cancer, especially when cancer is not associated with tobacco. The impact of smoking on quality of care for patients is actually not enough considered. A literature review conducted by the French National Cancer Institute emphasizes the importance of tobacco cessation to improve the prognosis (decreased mortality from all causes and specific); to reduce the risk of second primary cancers; to reduce per- and post-surgical risks as long as some toxicities related to treatments and to improve the quality of physical and mental life of patients. It is important that a communication with the patient takes place at the beginning of the treatment to impact the smoking behavior. All oncology health professionals should deliver a clearly and personalized cessation advice in the light of scientific data and ensure that smoking cessation help will be offered to the patient.

Abstract
INTRODUCTION This study characterizes tobacco cessation patterns and the association of cessation with survival among lung cancer patients at Roswell Park Cancer Institute: an NCI Designated Comprehensive Cancer Center. METHODS Lung cancer patients presenting at this institution were screened with a standardized tobacco assessment, and those who had used tobacco within the past 30 days were automatically referred to a telephone-based cessation service. Demographic, clinical information, and self-reported tobacco use at last contact were obtained via electronic medical records and the Roswell Park Cancer Institute tumor registry for all lung cancer patients referred to the service between October 2010 and October 2012. Descriptive statistics and Cox proportional hazards models were used to assess whether tobacco cessation and other factors were associated with lung cancer survival through May 2014. RESULTS Calls were attempted to 313 of 388 lung cancer patients referred to the cessation service. Eighty percent of patients (250 of 313) were successfully contacted and participated in at least one telephone-based cessation call; 40.8% (102 of 250) of persons contacted reported having quit at the last contact. After controlling for age, pack year history, sex, Eastern Cooperative Oncology Group performance status, time between diagnosis and last contact, tumor histology, and clinical stage, a statistically significant increase in survival was associated with quitting compared with continued tobacco use at last contact (HR = 1.79; 95% confidence interval: 1.14-2.82) with a median 9 month improvement in overall survival. CONCLUSIONS Tobacco cessation among lung cancer patients after diagnosis may increase overall survival.

Abstract
High prevalence of tobacco use and low success in quitting remain significant problems for reducing disease burden among HIV-infected persons. This study's purpose was to examine participant responsiveness and tobacco dependence treatment adherence and their influences on tobacco abstinence among HIV-infected patients. This non-randomized study included HIV-infected smokers 18 years of age or older, who smoked at least 5 cigarettes per day, and had an interest in quitting smoking in the next 30 days. HIV-infected smokers (n = 247) received a 12-week tobacco dependence treatment intervention that included pharmacotherapy and telephone counseling. Younger age and non-White race were associated with lower adherence to pharmacotherapy. Younger age, non-White race, and increased monthly binge drinking were associated with lower adherence to telephone counseling. High participant responsiveness was associated with adherence to pharmacotherapy, counseling, and abstinence. Development and testing of interventions to improve adherence to evidence-based tobacco dependence treatment is warranted.

While studies delineating the relationship between smoking cessation strategies and lung cancer screening programs remain sparse, we aim to review available data on their importance both individually and synergistically. Strategies and obstacles for implementation are also discussed.

Abstract
Although a well-established risk factor for lung cancer, the impact of smoking on the survival of non-small cell lung cancer (NSCLC) is not well known. We performed a retrospective analysis of the Veteran's Affairs Comprehensive Cancer Registry of NSCLC patients. Smoking status was categorized as never smoker, past smoker and current smoker based on self-reported history. Multivariate analysis was performed to evaluate the impact of smoking on overall survival (OS) from NSCLC. The study population (n = 61,440) comprised predominantly of males (98 %) and Caucasians (81 %). The median age at diagnosis was 68 years (range 22-108 years). Current smokers were diagnosed with NSCLC at a younger age (65 years) compared to never smokers (71 years) and past smokers (72 years) (p < 0.001). On multivariate analysis, current smokers (n = 34,613) [Hazard ratio (HR) 1.059; 95 % confidence interval (CI) 1.012-1.108], but not past smokers (n = 23,864) (HR 1.008; 95 % CI 0.962-1.056), had worse OS for Stage III and IV NSCLC, compared to never smokers (n = 2,963). Smoking status was not prognostic in stages I and II NSCLC. Current smokers were diagnosed with NSCLC at a younger age than never smokers. Although current smoking was associated with worse prognosis, especially in stages III and IV, the impact of smoking status on OS was modest.

Abstract
BACKGROUND Studies evaluating smoking cessation treatment outcomes in cancer patients are scarce, despite smoking cessation importance in cancer care. We sought to add to the literature by evaluating smoking cessation in a challenging group of cancer patients (medium-to-heavy smokers) visiting an out-patient smoking cessation clinic (SCC) in a cancer center in Amman, Jordan. MATERIALS AND METHODS Patients smoking >9 cigarettes per day (CPD) and referred to the SCC between June 2009 and May 2012 were studied. Clinic records were reviewed to measure demographic and baseline clinical characteristics, and longitudinal (3-, 6- and 12- month) follow- up by phone/clinic visit was conducted. At each follow-up, patients were asked if they experienced medication side-effects, if they had returned to smoking, and reasons for failing to abstain. Descriptive and multivariable logistic regression analyses were performed. RESULTS A total of 201 smokers were included in the analysis. The 3-month abstinence was 23.4% and significantly associated with older age, being married, and presenting with lower (≤ 10 ppm) baseline carbon monoxide (CO) levels. On a multivariable level, lower CO levels, a higher income (relative to the lowest income group), being older, and reporting severe dependence (relative to dependence reported as 'somewhat' or 'not') were significant predictors of higher odds of abstinence at three months. Reasons for failing to quit included not being able to handle withdrawal and seeing no value in quitting. Long- term ARs did not reach 7%. CONCLUSIONS In a sample of Jordanian smokers (>9CPD) with cancer and receiving smoking cessation treatment, ARs were low and further declined with time. Results underscore the need for more aggressive patient management and rigorous follow-up during and after smoking cessation treatment, particularly when this takes place in challenging settings. Observed reasons for failure to abstain should be used to tailor counseling practices.

Abstract
Survivors of lung cancer surgery are among the highest-risk patients for developing another lung cancer, yet there is no clear consensus on the method of surveillance for patients after curative surgical resection. Surveillance is no longer futile because the emergence of computed tomography screening has allowed the detection of recurrences and new metachronous cancers at an early stage. In selected patients, lung cancer identified recently on routine computed tomography scan is amenable to curative treatment and is associated with longer survival.

Abstract
To study epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) resistance mechanisms, we established a novel gefitinib-resistant lung cancer cell line derived from an EGFR-mutant non-small cell lung cancer cell line (PC-9) pretreated with 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (designated PC9-GR). We found that gefitinib substantially suppressed the EGFR signaling pathway, whereas ERK was reactivated after several hours in PC9-GR but not in PC-9. The combination of gefitinib with ERK inhibition (by U0126) restored gefitinib susceptibility in PC9-GR, but PI3K-Akt inhibition with LY294002 did not. Although the levels of phosphorylated Src were up-regulated simultaneously with ERK reactivation, neither ERK suppression using U0126 nor an ERK-specific siRNA induced Src phosphorylation. Furthermore, dual inhibition of EGFR and Src restored gefitinib sensitivity in PC9-GR in vitro and in vivo. In conclusion, our results indicate that Src-mediated ERK reactivation may play a role in a novel gefitinib resistance mechanism, and that the combined use of gefitinib with a Src inhibitor may be a potent strategy to overcome this resistance.

Abstract
BACKGROUND Cigarette smoking is one of the major causes of lung cancer. However, the correlation between smoking status and the survival of patients with lung cancer is uncertain. The present study aimed to evaluate the impact of smoking status on the mortality of patients with non-small cell lung cancer (NSCLC). METHODS The medical records of 313 patients newly diagnosed with NSCLC between January 2005 and January 2006 were reviewed. Eligible patients were divided into ever-smokers (221 patients) and never-smokers (92 patients), and the overall survival and clinical characteristics of the two groups were compared. Predictors of survival were analyzed using Cox's proportional hazards regression. RESULTS In ever-smokers, the mean age was higher, and male gender and squamous histology were predominant compared to never-smokers. The median survival time was longer in never-smokers (21.1 vs. 41.9 months, ever-smokers vs. never-smokers, respectively; P = 0.027). Overall survival estimates at 12, 24, and 60 months were 62.9 versus 82.6%, 43.4 versus 65.2%, and 31.2 versus 42.4%, in each group. Advanced age, advanced disease stage (stages III and IV), and coexistence of interstitial lung disease were analyzed as independent risk factors for shorter survival. Although ever-smoking was not an independent risk factor, current smoking was a risk factor for higher mortality. CONCLUSIONS The overall mortality of ever-smokers was higher than that of never-smokers in patients with newly diagnosed NSCLC, and current smoking was an independent risk factor for a poorer prognosis.

Abstract
BACKGROUND Lung cancer is the leading cause of death from cancer in Germany. 90% of cases are due to the inhalation of tobacco smoke. About 40% of patients with newly diagnosed lung cancer are still smokers. A structured smoking cessation program is medically reasonable in this situation but is only rarely offered. METHODS This review is based on a selective search in the PubMed database combined with a manual search for current publications. RESULTS Many cross-sectional and longitudinal studies have shown that patients with lung cancer benefit from smoking cessation. After resection with curative intent, second tumors are 2.3 times more common, and recurrent tumors 1.9 times more common, in patients who continue to smoke than in those who stop. The overall mortality in smokers is 2.9 times higher. Smoking cessation also lowers the rate of radiation pneumonitis and infection during radiotherapy and prolongs the median survival after chemoradiotherapy for small-cell lung cancer (18.0 vs. 13.6 months). For patients with non-small-cell lung cancer, smoking cessation is associated with a better general state of health (77.5% vs. 57.6%). For the many patients with lung cancer who are treated palliatively, smoking cessation offers the advantages of improved pulmonary function, weight gain, and better overall quality of life. CONCLUSION Smoking cessation in patients with lung cancer is an important means of increasing the efficacy of treatment and improving their quality of life.

Abstract
BACKGROUND The objectives of this study were to evaluate survival among current smokers, former smokers, and never smokers who are diagnosed with non-small cell lung cancer (NSCLC). METHODS The study included patients who participated in the National Comprehensive Cancer Network's NSCLC Database Project. Current, former, and never smokers were compared with respect to overall survival by fitting Cox regression models. RESULTS Data from 4200 patients were examined, including 618 never smokers, 1483 current smokers, 380 former smokers who quit 1 to 12 months before diagnosis, and 1719 former smokers who quit >12 months before diagnosis. Among patients with stage I, II, and III disease, only never smokers had better survival than current smokers (hazard ratio, 0.47 [95% confidence interval, 0.26-0.85] vs 0.51 [95% confidence interval, 0.38-0.68], respectively). Among patients with stage IV disease, the impact of smoking depended on age: Among younger patients (aged ≤55 years), being a never smoker and a former smoker for ≥12 months increased survival. After age 85 years, smoking status did not have a significant impact on overall survival. CONCLUSIONS Patients who were smoking at the time of diagnosis had worse survival compared with never smokers. Among younger patients with stage IV disease, current smokers also had worse survival compared with former smokers who quit >12 months before diagnosis. It is likely that tumor biology plays a major role in the differences observed; however, to improve survival, it is prudent to encourage all smokers to quit smoking if they are diagnosed with NSCLC.

Abstract
Tobacco smoking and HIV infection increase the risk of epidermoid anal cancer (EAC). No published studies have examined smoking and EAC outcomes, and the literature is discrepant regarding outcomes of HIV-positive patients with EAC. The goal of this study was to examine smoking history, HIV status and outcomes in EAC patients. We conducted a retrospective analysis of adults with invasive EAC treated in the University of Washington hospital system from 1 January 1994 to 31 December 2008. Sixty-three patients were included. Forty-seven patients (75%) had primary chemoradiation, of whom 42 (89%) completed therapy. Two patients (3%) received radiotherapy alone. Fourteen patients (22%) underwent primary surgery, of whom 11 (79%) underwent tumour excision and three (21%) abdominoperineal resection (APR). We analysed smoking history, HIV status and CD4 count (≥200 cells/μL/<200 cells/μL for HIV-positive patients) versus outcomes. Forty-five patients (71%) were in remission, and 44 (70%) were alive at last follow-up. Overall survival was significantly better for never-smokers than for ever-smokers. There were no differences in outcomes according to HIV status or CD4 counts. Patients with anal cancer who smoke have worse overall survival than non-smoking patients. HIV infection does not appear to affect anal cancer outcomes.

Abstract
Epidemiologic studies have shown that most cases of lung cancers (85%-90%) are directly attributable to cigarette smoking. Although much information has been gained about the effects of cigarette smoking on various signaling pathways causing lung cancer, nothing is known about the effect of cigarette smoking on the TGF-β-induced tumor suppressor function in lung cancer. To address this issue, lung adenocarcinoma A549 and immortalized bronchial epithelial HPL1A cells were chronically treated with cigarette smoke condensate (CSC) and dimethyl sulfoxide (as a control) to mimic the conditions of long-term cigarette smoking. Prolonged exposure of these cells to CSC resulted in a decrease in Smad3 and Smad4 complex formation and TGF-β-mediated transcription due to reduced expression of Smad3. Long-term CSC treatment reduced apoptosis, increased cell viability, decreased TGF-β-mediated growth inhibition, and enhanced tumorigenicity. The decrease in apoptosis is due to the upregulation of Bcl-2, which is a downstream target of Smad3. Re-expression of Smad3 in the CSC-treated cells restored TGF-β signaling, increased apoptosis, and decreased cell viability and tumorigenicity. Withdrawal of CSC treatment resulted in the restoration of Smad3 expression, reduction in cell viability, and increased TGF-β-mediated growth inhibition. Expression of Smad3 is lower in lung tumors of current smokers than that observed in never-smokers. Collectively, these data provide evidence that cigarette smoking promotes tumorigenicity partly by abrogating TGF-β-mediated growth inhibition and apoptosis by reducing expression of Smad3.

Abstract
BACKGROUND Tobacco use among cancer patients is associated with adverse health outcomes. Little attention has been paid to tobacco use among cancer patients in developing countries, including Russia, where tobacco use is extremely high, and there is little public health infrastructure to address this issue. PURPOSE This study examined medical, socio-demographic, and psychological correlates of smoking status and intention to quit smoking among newly diagnosed Russian cancer patients. METHOD A cross-sectional study was conducted with 294 current or former smokers newly diagnosed with cancer. RESULTS Compared with patients who quit smoking, patients who continued to smoke were more likely to report urges to smoke to satisfy positive reinforcing aspects of tobacco use. Compared with patients who were smoking and reported no intention to quit smoking in the next 3 months, patients who were smoking but intended to quit smoking reported higher levels of perceived risks associated with continued smoking and higher levels of self-efficacy to quit smoking. CONCLUSION As commitment to developing smoking cessation treatment programs for cancer patients in Russia emerges, these data can help guide the development of behavioral interventions to assist patients with quitting smoking, enhancing their chances for improved clinical outcomes.

Difference in survival and prognostic factors between smokers and never-smokers with advanced non-small-cell lung cancer. Int J Clin Oncol 2011; 18:17-25.

Abstract
BACKGROUND Our aims were to investigate whether the association between smoking and survival is significant when adjusted for prognostic factors including use of epidermal growth factor tyrosine kinase inhibitors and the Glasgow Prognostic Score, an established score for inflammation, and to explore prognostic factors. METHODS We analyzed 244 patients with stage IIIB or IV non-small-cell lung cancer in a registry, including only chemotherapy-receiving outpatients with performance status zero. RESULTS Of 244 patients, 170 had died and the median follow-up time for the 74 surviving patients was 12.0 months. In multivariate Cox regression, smoker (hazard ratio compared to never-smoker: 1.67, P < 0.01), stage IV (hazard ratio compared to IIIB: 1.72, P < 0.01), and elevated C-reactive protein level (hazard ratio per 1 mg/dL increase: 1.08, P < 0.01) were significantly associated with shorter survival. The association between survival and smoking was significant, even after adjustment for the Glasgow Prognostic Score and regimens of chemotherapy (hazard ratio: 1.72, P = 0.02). In never-smokers, increased neutrophils were a major determinant of shorter survival and the interaction test between smoking and neutrophils was significant (hazard ratio per 1,000/mm(3) increase for smokers: 1.01; hazard ratio per 1,000/mm(3) increase for never-smokers: 1.44, P for interaction <0.01). CONCLUSIONS Known factors including treatment response or inflammatory process are not responsible for the fact that advanced non-small-cell lung cancer patients without any history of smoking have better survival than those who have smoked.

Abstract
This survey, conducted in region Rhône-Alpes (France), aims to assess some data in thoracic oncology practice including availability of specialized equipments. This study is based on a questionnaire mailed to oncologists and pulmonologists in the region. Of 401 questionnaires, the response rate was 56%. Responses of 71 (20%) physicians practicing thoracic oncology are presented in this article. Eighty percent of physicians routinely screen occupational exposure in case of lung cancer. The oncologists are less likely than pulmonologists to screen it (50% vs. 12%, p = 0.0015). Sixty-one percent of practitioners do not routinely propose smoking cessation in stage IV. Sixty-nine percent of practitioners' reports obtain an appointment for PET-scanner within 15 days and 72% indicate that this equipment is located within 50 km of their place of practice. Sixty-two percent reports using a surgical team specialized in chest disease, which is located in their city in 77% of cases. Sixty-one percent say that the period between the decision of an emergency radiotherapy and the start of it is less than one week. In 73% radiotherapy department is located in their city of practice. Forty-one percent of practitioners say they have a centralized and specialized preparation unit for cancer drugs. It seems that specialized equipment in Rhône-Alpes is adapted to practice with the exception of units dedicated to the preparation of cytotoxic drugs.

Abstract
The serotonergic system may be involved in smoking behavior since the intake of nicotine increases serotonin secretion in the CNS. Moreover, evidence supporting the beneficial effect of selective serotonin reuptake for quitting smoking suggesting that the serotonin transporter (5-HTT) is a plausible target for the understanding and elucidation of smoking behavior. The transcriptional activity of its human gene (SLC6A4) is modulated by a polymorphism described in the second intron, the STin2 VNTR, which thus may interfere with 5-HTT synthesis. In this study was analyzed the polymorphism STin2 VNTR of 60 smokers male patients diagnosed for oral carcinoma, 61 male smokers without cancer and 65 non-smoker healthy blood donors. The STin2. 9 allele carriers were more present in smoker groups (with cancer and without cancer, respectively) than in the non-smoker (OR = 7.11, 95% CI = 0.83-60.91 and OR = 24.73; IC 95% = 3.17-192.66). Conversely, individuals carrying allele 10 were more prevalent in non-smokers compared with smokers (oral cancer patients and individuals without cancer, respectively), showing a protective factor of this allele (OR = 0.56; 95% CI = 0.24-1.33 and OR = 0.46; 95% CI = 0.20-1.07). This is the first report of a study assessing the importance of STin2 VNTR smoking behavior in Brazilian individuals and the association of STin2. 9 allele carriers in nicotine dependence. It is suggested that individuals with low serotonin concentration in the central nervous system, probably due to the presence of the allele for high expression of 5-HTT,especially STin2. 9, were more susceptible to nicotine dependence. Moreover, individuals with the 10 allele might have less risk for nicotine dependence.

Abstract
BACKGROUND Survival outcomes of never smokers with non-small cell lung cancer (NSCLC) who undergo surgery are poorly characterized. This investigation compared surgical outcomes of never and current smokers with NSCLC. METHODS This investigation was a single-institution retrospective study of never and current smokers with NSCLC from 1975 to 2004. From an analytic cohort of 4,546 patients with NSCLC, we identified 724 never smokers and 3,822 current smokers. Overall, 1,142 patients underwent surgery with curative intent. For survival analysis by smoking status, hazard ratios (HRs) were estimated using Cox proportional hazard modeling and then further adjusted by other covariates. RESULTS Never smokers were significantly more likely than current smokers to be women (P < .01), older (P < .01), and to have adenocarcinoma (P < .01) and bronchioloalveolar carcinoma (P < .01). No statistically significant differences existed in stage distribution at presentation for the analytic cohort (P = .35) or for the subgroup undergoing surgery (P = .24). The strongest risk factors of mortality among patients with NSCLC who underwent surgery were advanced stage (adjusted hazard ratio, 3.43; 95% CI, 2.32-5.07; P < .01) and elevated American Society of Anesthesiologists classification (adjusted hazard ratio, 2.18; 95% CI, 1.40-3.40; P < .01). The minor trend toward an elevated risk of death on univariate analysis for current vs never smokers in the surgically treated group (hazard ratio, 1.20; 95% CI, 0.98-1.46; P = .07) was completely eliminated when the model was adjusted for covariates (P = .97). CONCLUSIONS Our findings suggest that smoking status at time of lung cancer diagnosis has little impact on the long-term survival of patients with NSCLC, especially after curative surgery. Despite different etiologies between lung cancer in never and current smokers the prognosis is equally dismal.

Abstract
OBJECTIVE Many cancer patients continue to smoke post diagnosis, yet there have been few smoking cessation trials for this population. Depression, which is prevalent among cancer patients, may be a barrier to cessation. METHODS This double-blind placebo-controlled trial randomized 246 cancer patients to 9 weeks of placebo or bupropion, stratifying by pre-treatment depression symptoms. In addition, all patients received transdermal nicotine and behavioral counseling. Primary outcomes were 7-day point-prevalence abstinence, biochemically confirmed, at the end of treatment (Week 12), and at 6 months post quit day (Week 27). Additional outcomes included: withdrawal, affect, quality of life, compliance, and side effects. RESULTS There was no main effect of bupropion vs. placebo on abstinence (Odds Ratio [OR] = 1.36, 95% CI: 0.38-4.81, p = .64). Patients with depression symptoms reported significantly lower abstinence rates vs. patients without depression symptoms (OR = .14, 95% CI: 0.02-0.80, p = .03). Bupropion increased abstinence rates, vs. placebo, more for participants with depression vs. those without depression symptoms. For patients with depression symptoms, bupropion reduced withdrawal symptoms and improved quality of life vs. placebo. CONCLUSIONS For patients with depression symptoms, bupropion increases abstinence rates, lowers withdrawal, and increases quality of life. However, abstinence rates among patients with depression symptoms were low vs. patients without depression symptoms, who exhibited similar abstinence rates when treated with bupropion or transdermal nicotine and counseling alone. These results can guide future smoking cessation intervention studies with cancer patients.

Abstract
Recently, third-line chemotherapy for advanced non-small cell lung cancer (NSCLC) was accepted as a reasonable therapeutic option in patients with a favorable performance status. In practice, however, palliative chemotherapy has been performed for patients with a favorable performance status, even after third-line chemotherapy. Although multiple cycles of palliative chemotherapy were performed for these patients, there are little data of observation for courses of treatment from first-line to the last chemotherapy. We reviewed the courses of treatment for 82 patients with advanced NSCLC that had been admitted for platinum-based chemotherapy as a first-line treatment. Additional cycles of palliative chemotherapy were provided as monotherapy, based on the attending physician's decision considering patient performance status and toxicity after disease progression for previous chemotherapy. The median number of chemotherapy lines and cycles were 2 and 7, respectively, from first-line to the last chemotherapy. The median overall survival was 24 months in the response group of first-line chemotherapy, compared to 15 months for the entire study group. In the response group, the median number of chemotherapy cycles was 15 and patients received a median of 3 lines of chemotherapy. A total of 33 patients were candidate third-line chemotherapy or more. The median survival was 23 months for patients treated with more than third-line chemotherapy, compared to 7 months for patients treated with less than second-line chemotherapy. We conclude that long-standing chemotherapy is not beneficial to all NSCLC patients. However, patients with a favorable response to first-line chemotherapy tend to receive a higher number and more cycles of chemotherapy than the non-response group. Furthermore, multi-line chemotherapy appears to increase survival in the response group. Further studies will be needed to confirm these results.

Abstract
Smoking is an established risk factor for pancreatic cancer; however, detailed examination of the association of smoking intensity, smoking duration, and cumulative smoking dose with pancreatic cancer is limited. The authors analyzed pooled data from the international Pancreatic Cancer Cohort Consortium nested case-control study (1,481 cases, 1,539 controls). Odds ratios and 95% confidence intervals were calculated by using unconditional logistic regression. Smoking intensity effects were examined with an excess odds ratio model that was linear in pack-years and exponential in cigarettes smoked per day and its square. When compared with never smokers, current smokers had a significantly elevated risk (odds ratio (OR) = 1.77, 95% confidence interval (CI): 1.38, 2.26). Risk increased significantly with greater intensity (> or =30 cigarettes/day: OR = 1.75, 95% CI: 1.27, 2.42), duration (> or =50 years: OR = 2.13, 95% CI: 1.25, 3.62), and cumulative smoking dose (> or =40 pack-years: OR = 1.78, 95% CI: 1.35, 2.34). Risk more than 15 years after smoking cessation was similar to that for never smokers. Estimates of excess odds ratio per pack-year declined with increasing intensity, suggesting greater risk for total exposure delivered at lower intensity for longer duration than for higher intensity for shorter duration. This finding and the decline in risk after smoking cessation suggest that smoking has a late-stage effect on pancreatic carcinogenesis.

Abstract
Thirteen to 20% of lung cancer patients continue to smoke after diagnosis. Guided by Self-regulation Theory, the purpose of this study was to examine illness perceptions over time in a sample of lung cancer patients. This prospective 1-group descriptive longitudinal design study included participants 18 years or older, with a lung cancer diagnosis within the past 60 days who self-reported smoking within the past 7 days. At baseline, patients completed a sociodemographics and tobacco use history questionnaire. The Illness Perception Questionnaire-Revised (IPQ-R) was repeated at 3 time points (baseline, 2-4 weeks, and 6 months). Fifty-two participants provided data for the IPQ-R at baseline, 47 at 2 to 4 weeks, and 29 at 6 months. Differences between mean scores for each illness representation attribute of the IPQ-R at repeated time points were calculated by within-subjects repeated-measures analysis of variance and Wilcoxon Signed-Rank Tests. Identity (baseline vs 2-4 weeks: P = .026; baseline vs 6 months: P = .005) and acute/chronic timeline (P = .018) mean scores significantly increased over time; personal and treatment control mean scores significantly decreased over time (P = .007 and P = .047, respectively). Understanding the context in which a patient perceives disease and smoking behavior may contribute to developing interventions that influence behavior change.

Abstract
BACKGROUND Many patients are active smokers at the time of a diagnosis of surgically resectable lung cancer. Perioperative smoking cessation is associated with improved survival, but the cost-effectiveness of a smoking cessation program initiated immediately before surgery is unknown. METHODS We developed a decision analytic Markov model to evaluate the incremental cost-effectiveness of a formal smoking cessation program. The parameter estimates were taken from the available literature. The model included the cost and effectiveness of the smoking cessation program, cost and incidence of perioperative complications, postoperative mortality, and utility measured in quality adjusted life years (QALY). Dollars per QALY and life year were calculated and one-way sensitivity analyses were performed. RESULTS The cost/QALY and cost/life year were $16,415 and $45,629 at 1 year after surgery and $2609 and $2703 at 5 years, respectively. Most sensitivity analyses showed the 1 year postsurgery cost/QALY estimates were less than $50,000, and all were less than $12,000 at 5 years. Cost-effectiveness estimates were most sensitive to the frequency of perioperative complications and the estimated short-term utility estimates. CONCLUSION A smoking cessation program initiated before surgical lung resection is cost-effective at both 1 and 5 years postsurgery. Providers should encourage patients who are still smoking to engage in formal smoking cessation programs.
