Haghparast M, Evazi MR, Darvish L. Tobacco smoking influences the side effects of radiation therapy-managed patients with various malignancies: A systematic review. J Med Imaging Radiat Sci 2024; 55:101430. [PMID: 38870612 DOI: 10.1016/j.jmir.2024.05.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Revised: 04/30/2024] [Accepted: 05/08/2024] [Indexed: 06/15/2024]
Abstract
BACKGROUND Tobacco smoking may decrease the effectiveness of radiation therapy. This is because tobacco smoking can cause inflammation and damage to surrounding tissues, which may interfere with radiation delivery to the tumor. Our aim of this study is to investigate the effect of tobacco smoking use on complications in radiotherapy as a systematic review. METHOD The articles searched from the MEDLINE, PubMed, EMBASE, and Web of Science databases. The search terms used were "radiotherapy", "outcome", "radiation therapy", "tobacco", "smoking", "complications", "side effects", "cancer", and "malignancy". PRISMA check list was used to assess the overall quality of evidence for each outcome. RESULT The outcomes of radiotherapy-inducing tobacco smoking in smokers are more than non-smokers including; high SPC (second primary cancer), decreased median overall survival, higher infections during treatment, increased fatigue (p = 0.027), increased pain (p = 0.009), poorer cognitive function (0.041), affected mouth opening (0.049), more speech disturbances (p = 0.017), higher metastasis risk (p = 0.031 and 0.019), higher locoregional recurrence risk (p = 0.027), oral mucositis (p = 0.03), mucositis severity related to higher tobacco exposure (p = 0.008), severe acute radiation skin reactions, and myocardial infarction. DISCUSSION Tobacco smoking appears to be the most significant modifiable factor influencing cancer treatment outcomes. As such, healthcare providers should take detailed notes on patients' smoking histories during both routine and future clinical studies. Beyond immediate cessation, cancer patients should undertake comprehensive smoking cessation programs. These programs can significantly boost the efficacy of radiotherapy and enhance overall patient outcomes.

Alcohol, Smoking, and Risks of Breast Cancer Recurrence and Mortality among Women with Luminal, Triple-Negative, and HER2-Overexpressing Breast Cancer. Cancer Epidemiol Biomarkers Prev 2024; 33:288-297. [PMID: 38019269 PMCID: PMC10872526 DOI: 10.1158/1055-9965.epi-23-1081] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 10/30/2023] [Accepted: 11/22/2023] [Indexed: 11/30/2023] Open
Abstract
BACKGROUND This study evaluates the relationship between smoking, alcohol, and breast cancer outcomes according to molecular subtype. METHODS This population-based prospective cohort consisted of 3,876 women ages 20 to 69 diagnosed with a first primary invasive breast cancer from 2004 to 2015 in the Seattle-Puget Sound region. Breast cancer was categorized into three subtypes based on estrogen receptor (ER), progesterone receptor (PR), and HER2 expressions: luminal (ER+), triple-negative (TN; ER-/PR-/HER2-), and HER2-overexpressing (H2E; ER-/HER2+). We fit Cox proportional hazards models to assess the association between alcohol consumption and smoking status at diagnosis and risks of recurrence, breast cancer-specific mortality, and all-cause mortality. RESULTS Histories of ever smoking [HR, 1.33; 95% confidence interval (CI), 1.01-1.74] and current smoking (HR, 1.59; 95% CI, 1.07-2.35) were associated with greater risk of breast cancer recurrence among TN cases. Smoking was also associated with greater risk of recurrence to bone among all cases and among luminal cases. Elevated risks of breast cancer-specific and all-cause mortality were observed among current smokers across all subtypes. Alcohol use was not positively associated with risk of recurrence or mortality overall; however, TN patients who drank four or more drinks per week had a decreased risk of recurrence (HR, 0.71; 95% CI, 0.51-0.98) and breast cancer-specific mortality (HR, 0.73; 95% CI, 0.55-0.97) compared with non-current drinkers. CONCLUSIONS Patients with breast cancer with a history of smoking at diagnosis have elevated risks of recurrence and mortality. IMPACT These findings underscore the need to prioritize smoking cessation among women diagnosed with breast cancer.

Abstract
Smoking, a common behavior that causes health risks among adults around the world, is closely associated with the risks of developing various kinds of cancers. Nevertheless, the impact of smoking on preoperative risks and postoperative outcomes of cancer surgeries has been largely overlooked. Extensive basic medical and clinical research findings and prognosis data demonstrate that smoking is associated with increased risks of multiple perioperative complications, and that smoking affects the general prognosis of patients. Smoking cessation during the preoperative and perioperative periods effectively reduces these risks and improves the long-term postoperative outcomes of cancer patients. At present, health workers and patients are not giving adequate attention to smoking cessation interventions and the quality of interventions available is poor. Herein, we discussed the necessity of comprehensive and standardized smoking cessation services and made recommendations regarding the implementation of comprehensive and standardized smoking cessation services, providing support for cancer patients to access evidence-based care during the perioperative period.

Abstract
OBJECTIVES Esaxerenone is a novel, non-steroidal mineralocorticoid receptor (MR) blocker with improved selectivity and affinity for MR. The objectives of this study were to model the population pharmacokinetics of esaxerenone in a diverse population and to evaluate the effect of covariates on pharmacokinetics parameters. METHODS A total of 8263 plasma esaxerenone concentrations from 166 healthy volunteers, 1097 hypertensive patients and 360 patients with diabetic nephropathy were pooled. A three-compartment model with sequential zero- and first-order absorption was used to describe the time-courses of plasma esaxerenone following single and multiple doses once daily for up to 12 weeks. Covariate effects were estimated using the full covariate modeling approach. Clinical relevance of covariates was ascertained using tornado plots. RESULTS Esaxerenone was estimated to have high bioavailability (85.3%), low clearance (3.28 L/h) and relatively large distribution volume at steady state (94.8 L). Body weight (-26 to +36%) and coadministration of itraconazole (+64%) or rifampicin (-68%) were associated with a greater influence on esaxerenone exposure. CONCLUSIONS The most influential covariates on esaxerenone exposure were coadministrations of itraconazole and rifampicin, followed by body weight. The clinical relevance of effects of renal impairment, mild to moderate hepatic impairment, and age is limited.

Brief intervention to enhance cessation of smokeless tobacco use in newly diagnosed patients with head and neck cancers: A randomized controlled trial in patient-relative dyads. Indian J Psychiatry 2023; 65:742-748. [PMID: 37645365 PMCID: PMC10461584 DOI: 10.4103/indianjpsychiatry.indianjpsychiatry_578_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Revised: 04/24/2023] [Accepted: 05/31/2023] [Indexed: 08/31/2023] Open
Abstract
Introduction Tobacco use is a major causative factor for head and neck cancers (HNC). Continued use of tobacco even after cancer diagnosis is common and is associated with all-cause and cancer-specific mortality, cancer recurrence and poor treatment response. Evidence suggests that behavioral interventions, help achieve greater smoking cessation rates in HNC patients. However, intervention studies focussed on HNC patients using smokeless tobacco, which is more common than smoking in India, are sparse. Materials and Methods We conducted a parallel arm randomized controlled trial (RCT) on dyads of patients with recently diagnosed HNC and a close relative. The experimental arm received a brief tobacco cessation intervention (BTCI) and the control arm received treatment as usual (TAU); 27 and 25 dyads in each arm completed the trial. Results Overall for the dyads using SLT, the relative risk of continuing to use SLT was 3.23 times higher (odds ratio = 7.01) if BTCI was not undertaken at one-month follow-up and 4.43 times higher (odds ratio = 8.65) at 3-months follow-up. For patients only, the relative risk of continuing to use SLT at one-month and 3-months follow-ups was 4.99 and 12.04 times higher, respectively, if BTCI was not undertaken. For relatives only, the corresponding relative risk values were 2.14 and 2.2. Conclusion We conclude that BTCI delivered to patient-relative dyads, compared to TAU, is effective in enhancing the discontinuation rates of the use of SLT in newly diagnosed patients with HNC. This form of intervention is significantly effective for discontinuing SLT use in the relatives too.

Abstract
Nicotine from inhaled combustible cigarette smoke is delivered rapidly to the brain, and sufficient unbound nicotine concentrations exert pharmacological effects. In addition to nicotine, combustible cigarette smoke also contains a significant number of toxicants that trigger perturbations, leading to an altered steady state due to differential expression of proteins. In this study, a physiologically based pharmacokinetic (PBPK) model for inhaled nicotine was used to simulate the influence of lysosomal change-driven tissue retention and plasma protein binding levels on nicotine pharmacokinetics (PK). A 3× increase in tissue lysosomal volumes lowered the nicotine brain maximum concentration (Cmax) by 20.8%. Similarly, a 50% increase in plasma protein binding also lowered the unbound plasma arterial nicotine Cmax by 39.4%. Such fundamental changes in nicotine disposition due to physiological changes in combustible cigarette smokers will lead to altered nicotine consumption and exposure-responses of other weakly basic drugs. Literature reports indicate that nicotine consumed from non-combustible products do not alter drug exposures, indicating fewer or less severe toxicant-driven perturbations with the use of these products. Although several other parameters influence nicotine PK, this PBPK modeling study shows that increased tissue retention and plasma protein binding reduce nicotine delivery to the brain and could lead to differential consumption of combustible cigarettes. These differences in physiological states among combustible cigarette smokers need to be evaluated and should be considered during therapeutic interventions.

Abstract
Previous studies have suggested that persistent tobacco smoking impairs survival in cutaneous melanoma, but the effects of smoking and other prognostic factors have not been described in detail. This study examined the association of smoking (persistent, former, or never) with melanoma-specific (MSS) and overall survival (OS) in patients with cutaneous melanoma treated in Southwest Finland during 2005 to 2019. Clinical characteristics were obtained from electronic health records for 1,980 patients. Smoking status was available for 1,359 patients. Patients were restaged according to the 8th edition of the tumour-node-metastasis (TNM) classification. Smoking remained an independent prognostic factor for inferior melanoma-specific survival regardless of age, sex, stage, and comorbidities. The hazard ratio of death from melanoma was 1.81 (1.27-2.58, p = 0.001) in persistent and 1.75 (1.28-2.40, p = 0.001) in former smokers compared with never smokers. In 351 stage IV patients, smoking was associated with increased melanoma-specific and overall mortality: median MSS 10.4 (6.5-14.3), 14.6 (9.1-20.1), and 14.9 (11.4-18.4) months, p = 0.01 and median OS 10.4 (6.5-14.3), 13.9 (8.6-19.2), and 14.9 (11.7-18.1) months, p = 0.01 in persistent, former, and never smokers, respectively. In conclusion, since smoking represents an independent modifiable poor prognostic factor in patients with cutaneous melanoma, smoking habits should be proactively asked about by healthcare professionals, in order to support smoking cessation.

Abstract
The smoking behaviour of patients following a cancer diagnosis is a critical risk factor for several physical diseases; it can increase the risk of second primary tumors and lower cancer treatment efficacy. Despite this, a great number of survivors continue to smoke after the diagnosis. This observational, cross-sectional on-line study aimed to assess the relationship between the impact of cancer diagnosis on survivors and their smoking behavior, and whether emotional intelligence and personality might mediate this relationship. Ninety-four Italian survivors completed a set of questionnaires: Big Five Inventory; Fagerström Test for Nicotine Dependence; Impact of Event Scale; Brief Emotional Intelligence Scale. The results obtained from the mediation analyses highlighted that the indirect effect on the relationship between the psychological impact of the diagnosis and smoking behaviors was partially mediated by neuroticism (Intrusion: 95% CI [0.00; 0.11]; Avoidance: 95% CI [0.00; 0.18]). Additionally, the data suggested that the relationship between the psychological impact of the diagnosis and smoking behaviors was partially mediated by the utilization of emotions dimension of emotional intelligence (Intrusion: 95% CI [0.00; 0.10]; Avoidance: 95% CI [0.00; 0.22]). Overall, this study suggests the importance of designing interventions to support smoking interruption based on the "mapping" of individual needs and emotional regulation strategies.

Abstract
OBJECTIVES To review the evidence supporting the modification of behavioral habits and substance use management during cancer treatment and how to implement them as part of a multimodal optimization intervention. DATA SOURCES A literature review of the association between cancer and behavioral habits, their impact on oncological treatment outcomes, and substance use management guidelines. CONCLUSION There is an association between harmful habits, such as smoking and alcohol consumption, and cancer. The continuation of poor behavioral habits throughout oncological treatments is associated with poor oncological outcomes and increased complications. Prehabilitation could be an ideal setting to screen, assess, and modify these harmful habits. Prehabilitation programs should be equipped with professionals and resources to help patients achieve harmful habit cessation. IMPLICATIONS FOR NURSING PRACTICE This review puts into manifest the importance of a multidisciplinary approach to substance use management. It can serve as a framework to develop a harmful habit cessation intervention in the context of multimodal prehabilitation to improve surgical and oncological outcomes in the cancer population.

Abstract
Smoking is a common health risk behavior that has substantial effects on perioperative risk and postoperative surgical outcomes. Current smoking is clearly linked to an increased risk of perioperative cardiovascular, pulmonary and wound healing complications. Accumulating evidence indicates that smoking cessation can reduce the higher perioperative complication risk that is observed in current smokers. In addition, continued smoking has a negative impact on the overall prognosis of cancer patients. Smoking cessation, on the other hand, can improve long-term outcomes after surgery. Smoking cessation services should be implemented in a comprehensive programmatic manner to ensure that all patients gain access to evidence-based care. Although the benefits of abstinence increase in proportion to the length of cessation, cessation should be recommended regardless of timing prior to surgery.

Abstract
INTRODUCTION Cigarette smoking represents the main risk factor for cancer development; however, less is known about the effects of active smoking on the outcome of cancer patients receiving systemic treatment, radiation therapy, or surgery. METHODS A systematic review and meta-analysis were conducted searching the PubMed® and Web of Science® Library databases using specific Medical Subject Headings terms. Studies reporting on the prognostic impact of the smoking status concerning survival endpoints in cancer patients treated with systemic treatment, radiation therapy, or surgery were eligible for inclusion. RESULTS Of 1.380 articles reviewed, 12 reports including data from 31.785 patients with six different cancer types were considered eligible for inclusion. According to the meta-analysis of the overall effect, active smoking during cancer treatment was associated with an impaired overall survival (OS) and cancer-specific mortality (CSM) as compared to former or never smokers (OS: hazard ratio (HR) = 1.61, 95% CI: 1.19-2.17, p = 0.007; CSM: HR = 1.25, 95% CI: 1.01-1.54, p = 0.046). Moreover, smoking cessation led to a similar OS and CSM when comparing former to never smoking patients (OS: HR = 1.01, 95% CI: 0.87-1.18, p = 0.818; CSM: HR = 1.04, 95% CI: 0.91-1.20, p = 0.324). CONCLUSION These results underline active smoking during cancer treatment as an independent adverse prognostic factor, while smoking cessation can result in similar outcomes compared to never smokers. Limitations of the study were a substantial study heterogeneity concerning different cancer entities and variations of treatment modalities.

OBJECTIVE To assess the interaction between chemotherapy and normal tissues is critical to assure quality of life during and after the treatment of cancer. This study evaluated the influence of cisplatin (CIS) and 5-fluorouracil (5-FU) over the peri-implant tissues around osseointegrated titanium implants in animals previously exposed to nicotine. Materials and methods One hundred twenty male rats were divided into two groups, receiving via subcutaneous injection, either physiological saline solution (PSS) (n = 30) or nicotine hemissulfate (NIC) (n = 90) for 30 days prior to implants' placement. One titanium implant (4.0 × 2.2 mm) was installed in each tibia of all animals. PSS and NIC were continued for 30 days after surgery. Five days after cessation, rats were subdivided into three subgroups in accordance with systemic treatments with either PSS, CIS, or 5-FU. Euthanasia was performed at 50, 65, and 95 days post-surgery. Histometric, histopathological, and immunohistochemical analyses were performed. RESULTS NIC-CIS and NIC-5FU presented lower BIC (50, 65, and 95 days) and bone area fraction occupancy (BAFO) (65 and 95 days) than group NIC. Intense inflammatory infiltration, severe tissue breakdown, reduced expression of bone formation biomarkers, and upregulation of TRAP were observed in NIC-CIS and NIC-5FU when compared with group NIC. TRAP expression was significantly higher in NIC-5FU as compared with NIC-CIS at 50 and 95 days. Groups NIC, NIC-CIS, and NIC-5FU presented statistically significant negative impact in all outcome parameters than group PSS. CONCLUSION CIS and 5-FU severely disrupted the peri-implant tissues around osseointegrated implants in animals previously exposed to nicotine. CLINICAL RELEVANCE Assessing the interaction between chemotherapy and normal tissues is critical to assure quality of life during and after the cancer treatment.

Interest in Cessation Treatment Among People Who Smoke in a Community-Based Multidisciplinary Thoracic Oncology Program. JTO Clin Res Rep 2021; 2:100182. [PMID: 34590029 PMCID: PMC8474282 DOI: 10.1016/j.jtocrr.2021.100182] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2021] [Revised: 04/13/2021] [Accepted: 04/23/2021] [Indexed: 12/02/2022] Open
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
Epidemiological and clinical studies over the past two decades have provided strong evidence that genetic elements interacting with environmental components can individually and collectively influence one’s susceptibility to cancer. In addition to tumorigenic properties, numerous environmental factors, such as nutrition, chemical carcinogens, and tobacco/alcohol consumption, possess pro-invasive and pro-metastatic cancer features. In contrast to traditional cancer treatment, modern therapeutics not only take into account an individual’s genetic makeup but also consider gene–environment interactions. The current review sharpens the focus by elaborating on the impact that environmental factors have on the pathogenesis and progression of head and neck cancer and the underlying molecular mechanisms involved. Recent advances, challenges, and future perspectives in this area of research are also discussed. Inhibiting key environmental drivers of tumor progression should yield survival benefits for patients at any stage of head and neck cancer.

Abstract
INTRODUCTION Smoking is well-known to increase cancer risk, particularly risk of lung cancer, and negatively affects efficacy of cancer treatment. However, recent evidence suggests that among cancer patients, paradoxically, smokers respond to treatment better than non-smokers. We propose to conduct a focused review and meta-analysis to compare response to drug treatment between smoking and non-smoking cancer patients. METHODS AND DESIGN We will collect data from large clinical trials of therapies for cancer patients which have included smokers and non-smokers. We will search PubMed, PMC/ MEDLINE, SCOPUS, Embase, and the registries for clinical trials and four major clinical journals up to June 30, 2019. Search terms will be "Drug name" phase-3" or "Drug name" phase-III." Data collection will be focused on randomized clinical trials of cancer drugs that enrolled at least 100 participants and reporting treatment results from smoking and nonsmoking patients. Initial selection criteria will be clinical trial studies of drug treatment of 100 or more cancer patients, and reporting hazard ratios (HR) for smokers and non-smokers. Two persons will be searching such publications independently, or data will be provided, double checked, or confirmed by authors. Multiple sub-group analyses will be conducted by at least two persons to avoid bias or experimental errors. DISCUSSION The results will clarify whether smoking and response to treatment of cancer are linked not. Our results may possibly identify drug/s that work better among cancer patients who are smokers. TRIAL REGISTRATION PROSPERO registration number: CRD42019146402.

Abstract
BACKGROUND The impact of smoking continuation or cessation on the outcome of head and neck cancer (HNC) patients concerning recurrence and survival rates is not well understood. We aimed to analyze the prognostic role of smoking habits in patients with newly diagnosed HNC and the effects on survival, recurrence rates, and second primary tumor (SPT) development. METHODS A systematic literature review of the databases PubMed and Web of Science was performed in October 2019 using the search words "head and neck cancer" and "smoking cessation." Articles analyzing the effects of ongoing smoking or smoking cessation in HNC patients were included. RESULTS Twelve studies published from 1993 to 2016 including 6,308 patients with HNC of stages I-IV were eligible for analysis. The median follow-up was 5 years. Six of 8 studies revealed an improved outcome concerning the median overall survival or survival rates favoring smoking cessation. Regarding recurrence rates, 5 of 6 studies indicated a statistically significant benefit associated with smoking cessation, and 2 of 3 studies showed a lower risk for SPT associated with postdiagnosis smoking cessation. CONCLUSION Smoking cessation in patients with newly diagnosed HNC is associated with improved outcomes concerning overall survival, recurrence rates, and SPTs. Further research is needed to validate these results and to evaluate the specific effects on different tumor types and treatment approaches.

Abstract
AbstractBackground:Prostate cancer is the most commonly diagnosed malignancy and the third leading cause of death among Canadian men. The standard treatment modalities for prostate cancer include prostatectomy, radiation therapy, hormonal therapy and chemotherapy or any combination depending on the stage of the tumour. However, several studies have reported that tobacco smoking at the time of diagnosis and during treatment can potentially impact treatment efficacy, outcome and patients quality of life after treatment.Materials and methods:This narrative literature review elucidates the impacts of tobacco smoking on prostate cancer progression, treatment efficacy, including its effects on prostatectomy, radiation therapy and chemotherapy, risk of cancer recurrence and mortality and quality of life after treatment. Furthermore, we discuss the importance of integrating a smoking cessation programme into the treatment regimen for prostate cancer patients in order to yield more favourable treatment outcomes, reduce risk of recurrence and mortality and increase the quality of life after treatment for prostate cancer patients.Conclusions:Smoking cessation is one of the most important interventions to prevent cancer and it is also essential after the diagnosis of prostate cancer to improve clinical outcomes. All prostate cancer patients should be advised to quit tobacco use since it can potentially improve treatment response rates and survival, as well as reduce the risk of developing treatment complications and potentially improve the quality of life after treatment. There are several benefits to smoking cessation and it should become an important component of the cancer care continuum in all oncology programmes, starting from prevention of cancer through diagnosis, treatment, survivorship and palliative care. Evidence-based smoking cessation intervention should be sustainably integrated into any comprehensive cancer programme, and the information should be targeted to the specific benefits of cessation in cancer patients.

Abstract
INTRODUCTION Major smoking effects have been reported for a series of psychotropic agents, mainly including substrates of CYP450 1A2, although smoking may also affect alternative metabolic pathways. To our knowledge, smoking effects on paliperidone pharmacokinetics have not been assessed yet. METHODS We compared plasma concentrations of paliperidone as well as dose-corrected-plasma concentrations (C/D) from a naturalistic database between smokers and nonsmokers using nonparametrical tests, such as the Mann-Whitney U-test (MWU). Additionally, we compared light and heavy smokers with nonsmokers separately. RESULTS Comparing 55 smokers with 37 nonsmokers treated with oral paliperidone, no differences in the percentage of females, age, body weight, body mass index, and daily paliperidone dose were reported (p=0.709 for χ2, p=0.26, p=0.38, p=0.67, and p=0.8 for MWU). No differences were detected in plasma concentrations or C/D values (p=0.50 and p=0.96 for MWU). Likewise, differences in daily dose, plasma concentrations, or C/D values were not significant between light smokers (n=17) and nonsmokers (p=0.61, p=0.81, and p=0.33 for MWU) or heavy smokers (n=22) and nonsmokers (p=0.874, p=0.38, and p=0.59; MWU in all cases). DISCUSSION Paliperidone is not affected by smoking, and paliperidone dose-adjustments in smokers may not be necessary. This may be seen as an essential difference to risperidone, whose cytochrome-mediated metabolism might be affected by smoking.

Abstract
INTRODUCTION Tobacco use is a major causative factor for cancer. Cessation programs along with diagnosis of cancer as a motivating factor may improve quitting rates in patients. This is a protocol of a study that aims to assess the efficacy of brief tobacco cessation intervention (compared to treatment as usual, TAU) on pattern and attitudes towards tobacco chewing in newly diagnosed head and neck cancer patients and their relatives. METHODS The proposed study will be conducted in two phases. Phase 1 will include 105 dyads of patients and relatives and shall assess patterns (amount, frequency, duration of use and dependence etc.) and knowledge and attitudes (quitting, continued use, health-behavioural modifications, long-term effects on treatment etc.) towards tobacco chewing in newly diagnosed head and neck cancer patients using smokeless tobacco and their relatives. Sample will be recruited from outpatients attending the ear, nose, throat and head and neck surgery department of a tertiary health care institute. Phase 2 will be a randomized trial that will compare the efficacy of the ‘Brief Intervention for Tobacco when Diagnosed with Oral Cancer’ (BITDOC) and TAU, and will include 27 dyads in each of the two groups. Intervention will be delivered in three sessions, based on the principles of motivational interviewing and the 3As model. CONCLUSIONS This study will help in the evaluation of the attitude towards smokeless tobacco (SLT) in a population that has faced the adverse consequences from its use and changes brought by a diagnosis of HNC. It will also help in developing a cost-effective model for promotion of smoking cessation.

Abstract
Lung cancer remains the most lethal cancer. The most common cause is smoking, which is also preventable, unlike the causes of other types of cancer. A genetic characteristic has emerged over several years, which explains particular profiles of smokers, or highly dependent smokers. The emergence of new therapies for the treatment of lung cancer, and the impact of tobacco on reducing the effectiveness of these therapies must challenge practitioners to obtain a complete cessation of smoking regardless of the stage of the disease.

Abstract
BACKGROUND AND OBJECTIVES Negative consequences of tobacco use during cancer treatment are well-documented but more in-depth, patient-level data are needed to understand patient beliefs about continued smoking (vs cessation) during gastrointestinal (GI) cancer treatment. METHODS We conducted semi-structured interviews with 10 patients who were active smokers being treated for GI cancers and 5 caregivers of such patients. All interviews were audio-recorded, transcribed verbatim, and uploaded to NVivo. We consensus coded data inductively using conventional content analysis and iteratively developed our codebook. We developed data matrices to categorize the themes regarding patient perspectives on smoking as well as presumed barriers to smoking cessation during active therapy. RESULTS Our interviews revealed three consistent themes: (a) Smoking cessation is not necessarily desired by many patients who have received a cancer diagnosis; (b) Failure in past quit attempts may lead to feelings of hopeless about future attempts, especially during cancer treatment; (c) Patients perceived little to no access to smoking cessation treatment at the time of their cancer diagnosis. CONCLUSIONS Well-designed systemic changes that promote the positive and efficacious effects of quitting smoking during cancer treatment, and that provide barrier-free access to such treatments may be helpful in promoting tobacco-free behavior during cancer treatment.

Abstract
The development of small-molecule tyrosine kinase inhibitors (TKIs) that target the epidermal growth factor receptor (EGFR) has revolutionized the management of non-small-cell lung cancer (NSCLC). Because these drugs are commonly used in combination with other types of medication, the risk of clinically significant drug–drug interactions (DDIs) is an important consideration, especially for patients using multiple drugs for coexisting medical conditions. Clinicians need to be aware of the potential for clinically important DDIs when considering therapeutic options for individual patients. In this article, we describe the main mechanisms underlying DDIs with the EGFR-TKIs that are currently approved for the treatment of NSCLC, and, specifically, the potential for interactions mediated via effects on gastrointestinal pH, cytochrome P450-dependent metabolism, uridine diphosphate-glucuronosyltransferase, and transporter proteins. We review evidence of such DDIs with the currently approved EGFR-TKIs (gefitinib, erlotinib, afatinib, osimertinib, and icotinib) and discuss several information sources that are available online to aid clinical decision-making. We conclude by summarizing the most clinically relevant DDIs with these EFGR-TKIs and provide recommendations for managing, minimizing, or avoiding DDIs with the different agents.

Abstract
AbstractBackground:The adverse health effects associated with smoking tobacco have been well investigated, and its detrimental effects on cancer treatment outcomes, efficacy and quality of life (QOL) for cancer patients have also been well documented. Tobacco smoke contains many thousands of chemicals, including a plethora of carcinogens, and the exposure of human cells to these carcinogens, and their metabolic activation, is the main mechanism by which smoking-related cancer is initiated.Materials and Methods:This paper reports on a narrative review of recent studies in the field of effects of tobacco smoking on cancer treatment, including the effects of carcinogens in smoke on carcinogenesis, cell mutations and the immune system. The health effects of smokeless tobacco, effects of tobacco smoking on cancer treatment, and its impact on surgery, radiation therapy and chemotherapy are reported. The potential risks of second primary cancers or recurrence from tobacco use, the effects of second-hand smoking and cancer treatment, the impact of smoking on the QOL after cancer treatment and the need to integrate smoking cessation programs into the cancer care continuum are also reported.Conclusions:Tobacco use has a direct impact on cellular function by inhibiting apoptosis, stimulating proliferation and decreasing the efficacy of cancer treatment; therefore, quitting its use has the potential to improve treatment response rates and survival, as well as reduces the risk of developing second cancers and potentially improves the QOL after treatment. Smoking cessation is one of the most important interventions to prevent cancer and is also essential after the diagnosis of cancer to improve clinical outcomes. Due to the numerous benefits of smoking cessation, it should become a critical component of the cancer care continuum in all oncology programs – from prevention of cancer through diagnosis, treatment, survivorship and palliative care. Evidence-based smoking cessation intervention should be sustainably integrated into any comprehensive cancer program, and the information should be targeted to the specific benefits of cessation in cancer patients.

Abstract
Introduction: Glioblastoma multiforme (GBM) has a poor prognosis despite maximal surgical resection with subsequent multi-modal radiation and chemotherapy. Use of tobacco products following diagnosis and during the period of treatment for non-neural tumors detrimentally affects treatment and prognosis. Approximately, 16-28% of patients with glioblastoma continue to smoke after diagnosis and during treatment. The literature is sparse for information-pertaining effects of smoking and nicotine on GBM treatment and prognosis. Areas covered: This review discusses cellular pathways involved in GBM progression that might be affected by nicotine, as well as how nicotine may contribute to resistance to treatment. Similarities of GBM pathways to those in non-neural tumors are investigated for potential effects by nicotine. English language papers were identified using PubMed, Medline and Scopus databases using a combination of keywords including but not limited to the following: nicotine, vaping, tobacco, e-cigarettes, smoking, vaping AND glioblastoma or brain cancer OR/AND temozolomide, carmustine, methotrexate, procarbazine, lomustine, vincristine, and neural tumor cell lines. Expert opinion: Understanding the impact of nicotine on treatment and resistance to chemotherapeutics should allow physicians to educate their patients with GBM with evidence-based recommendations about the effects of continuing to use nicotine-containing products after diagnosis and during treatment.

Abstract
The World Health Organization has estimated that, worldwide, cigarette smoking has caused more than 100 million deaths in the last century, a number that is expected to increase in the future. Understanding cigarette smoke toxicity is key for research and development of proper public health policies. The current challenge is to establish a reliable preclinical model to evaluate the effects of cigarette smoke. In this work, we describe a simple method that allows for quantifying the toxic effects of cigarette smoke using zebrafish. Here, viability of larvae and adult fish, as well as the effects of cigarette smoke extracts on vascular development and tissue regeneration, can be easily assayed. © 2019 by John Wiley & Sons, Inc.

Abstract
Purpose: To develop peripheral blood mRNA expression profiles of drug metabolizing enzymes (DMEs) as a surrogate to monitor tobacco induced head and neck squamous cell carcinoma (HNSCC), attempts were made to investigate (i) similarities in alterations with the cancer marker genes in biopsy samples and (ii) if alterations similar to that seen in biopsy samples are reflected in peripheral blood. Methods: Total RNA from eight soft gingival tissues and eight biopsy samples of HNSCC patients and total DNA and RNA from blood of healthy controls (n = 150) and HNSCC patients (n = 150) was processed for expression and genotyping studies. Blood from patients receiving chemo-radiotherapy was processed for follow-up study. Results: qRT-PCR revealed significant increase in mRNA expression of DMEs in biopsy and blood samples of HNSCC patients when compared to controls. Similar alterations were observed in cancer marker genes in these samples. Patients with variant genotypes of DMEs showed greater magnitude of alterations in mRNA expression when compared to wild type controls. Responders of chemo-radiotherapy showed significant decline in induction of mRNA expression of DMEs and cancer marker genes Conclusions: The data suggest that peripheral blood expression profiles could be used to monitor tobacco-induced HNSCC as well as the treatment response.

Abstract
BACKGROUND Guanfacine is Food and Drug Administration approved for hypertension and attention-deficit hyperactivity disorder and has been used off-label for migraine prophylaxis, heroin withdrawal, and more recently smoking cessation. Previous studies have shown positive effects of 3 mg/d of immediate-release (IR) guanfacine on smoking outcomes, but the dose equivalency of the IR and extended-release (ER) formulations is unknown. PROCEDURES A within-subject design was used to compare the pharmacokinetics and pharmacodynamics of 3 mg/d of IR, 4 mg/d of ER, and 6 mg/d of ER guanfacine in adult daily smokers (n = 5). Plasma medication levels, vital signs, cigarettes per day, tobacco craving, and adverse events were assessed. Medication was titrated to stable dosing after each laboratory day (3 mg/d IR, then 4 mg/d ER, then 6 mg/d ER). RESULTS Plasma medication levels did not differ between the 3 mg/d of IR and 4 mg/d of ER doses after 24 hours from last dose and were highest at the 6 mg/d of ER dose (3 mg/d IR: M = 3.40 ng/mL, SE = 0.34 vs 4 mg/d ER: M = 3.46 ng/mL, SE = 0.67 vs 6 mg/d ER: M = 5.92 ng/mL, SE = 1.02). All doses of guanfacine decreased heart rate and blood pressure from baseline. Absolute values of cigarettes per day (6 mg/d ER) and tobacco craving (4 and 6 mg/d ER) were lowest with the ER formulations. Treatment-emergent adverse events were subject rated as minimal to mild, except dry mouth. CONCLUSIONS We demonstrated similar pharmacokinetic profiles between 3 mg/d of IR guanfacine and 4 mg/d of ER guanfacine, as hypothesized. All doses of guanfacine were well tolerated.

Abstract
Smoking is a well-known behavior that has an important negative impact on human health, and is considered to be a significant factor related to the development and progression of head and neck squamous cell carcinomas (HNSCCs). Use of high-dimensional datasets to discern novel HNSCC driver genes related to smoking represents an important challenge. The Cancer Genome Atlas (TCGA) analysis was performed in three co-existing groups of HNSCC in order to assess whether gene expression landscape is affected by tobacco smoking, having quit, or non-smoking status. We identified a set of differentially expressed genes that discriminate between smokers and non-smokers or based on human papilloma virus (HPV)16 status, or the co-occurrence of these two exposome components in HNSCC. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways classification shows that most of the genes are specific to cellular metabolism, emphasizing metabolic detoxification pathways, metabolism of chemical carcinogenesis, or drug metabolism. In the case of HPV16-positive patients it has been demonstrated that the altered genes are related to cellular adhesion and inflammation. The correlation between smoking and the survival rate was not statistically significant. This emphasizes the importance of the complex environmental exposure and genetic factors in order to establish prevention assays and personalized care system for HNSCC, with the potential for being extended to other cancer types.

Abstract
Breast cancer is the most common type of cancer in females and the second most common cause of cancer mortality after lung cancer. Cancer stem cells represent a novel approach to target cancer and reduce cancer recurrence and metastasis. Many patients with breast cancer continue to smoke after receiving their diagnosis. Nicotine is a key factor in tobacco addiction and also changes some cellular functions, such as activation of mitogenic pathways, angiogenesis and cell proliferation. In the present study, the impact of nicotine was assessed in a population of MCF-7 human breast cancer cells. Cluster of differentiation (CD)44+CD24− cancer stem cell population of MCF-7 cells were evaluated using flow cytometry and scanning electron microscopy. Chemoresistance effects of nicotine were demonstrated in these cells. These findings demonstrated harmful effects of nicotine following metastasis of cancer, owing to the chemoresistance produced through uninterrupted smoking, which may impact the effectiveness of treatment.

Toxicology 2018; 398-399:1-12.

Abstract
Polycyclic aromatic hydrocarbons such as benzo[a]pyrene (BaP) can induce cytochrome P450 1A1 (CYP1A1) via a p53-dependent mechanism. The effect of different p53-activating chemotherapeutic drugs on CYP1A1 expression, and the resultant effect on BaP metabolism, was investigated in a panel of isogenic human colorectal HCT116 cells with differing TP53 status. Cells that were TP53(+/+), TP53(+/-) or TP53(-/-) were treated for up to 48 h with 60 μM cisplatin, 50 μM etoposide or 5 μM ellipticine, each of which caused high p53 induction at moderate cytotoxicity (60-80% cell viability). We found that etoposide and ellipticine induced CYP1A1 in TP53(+/+) cells but not in TP53(-/-) cells, demonstrating that the mechanism of CYP1A1 induction is p53-dependent; cisplatin had no such effect. Co-incubation experiments with the drugs and 2.5 μM BaP showed that: (i) etoposide increased CYP1A1 expression in TP53(+/+) cells, and to a lesser extent in TP53(-/-) cells, compared to cells treated with BaP alone; (ii) ellipticine decreased CYP1A1 expression in TP53(+/+) cells in BaP co-incubations; and (iii) cisplatin did not affect BaP-mediated CYP1A1 expression. Further, whereas cisplatin and etoposide had virtually no influence on CYP1A1-catalysed BaP metabolism, ellipticine treatment strongly inhibited BaP bioactivation. Our results indicate that the underlying mechanisms whereby etoposide and ellipticine regulate CYP1A1 expression must be different and may not be linked to p53 activation alone. These results could be relevant for smokers, who are exposed to increased levels of BaP, when prescribing chemotherapeutic drugs. Beside gene-environment interactions, more considerations should be given to potential drug-environment interactions during chemotherapy.

Abstract
Cigarette smoking (CS) adversely affects the physiologic function of endothelial progenitor, hematopoietic stem and progenitor cells. However, the effect of CS on the ability of adipose stem/stromal cells (ASC) to promote vasculogenesis and rescue perfusion in the context of ischemia is unknown. To evaluate this, ASC from nonsmokers (nCS-ASC) and smokers (CS-ASC), and their activity to promote perfusion in hindlimb ischemia models, as well as endothelial cell (EC) survival and vascular morphogenesis in vitro were assessed. While nCS-ASC improved perfusion in ischemic limbs, CS-ASC completely lost this therapeutic effect. In vitro vasculogenesis assays revealed that human CS-ASC and ASC from CS-exposed mice showed compromised support of EC morphogenesis into vascular tubes, and the CS-ASC secretome was less potent in supporting EC survival/proliferation. Comparative secretome analysis revealed that CS-ASC produced lower amounts of hepatocyte growth factor (HGF) and stromal cell-derived growth factor 1 (SDF-1). Conversely, CS-ASC secreted the angiostatic/pro-inflammatory factor Activin A, which was not detected in nCS-ASC conditioned media (CM). Furthermore, higher Activin A levels were measured in EC/CS-ASC cocultures than in EC/nCS-ASC cocultures. CS-ASC also responded to inflammatory cytokines with 5.2-fold increase in Activin A secretion, whereas nCS-ASC showed minimal Activin A induction. Supplementation of EC/CS-ASC cocultures with nCS-ASC CM or with recombinant vascular endothelial growth factor, HGF, or SDF-1 did not rescue vasculogenesis, whereas inhibition of Activin A expression or activity improved network formation up to the level found in EC/nCS-ASC cocultures. In conclusion, ASC of CS individuals manifest compromised in vitro vasculogenic activity as well as in vivo therapeutic activity. Stem Cells 2018;36:856-867.

Abstract
The new 8th edition AJCC/UICC staging system for human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC), developed to account for improved survival outcomes over HPV-negative cancers, includes anatomic features strictly associated with tumor-node-metastasis (TNM) and does not account for patient-specific characteristics that may impact prognosis. This commentary evaluates the evidence of smoking as an adverse prognostic factor in HPV-associated OPSCC. We review the multifactorial biological, clinical, and social/behavioral characteristics of smokers with OPSCC that impact outcomes, discuss current challenges with incorporating smoking history in prognostic classifications, and consider opportunities for future investigation.

Abstract
Afatinib is an oral, irreversible ErbB family blocker that covalently binds to the kinase domains of epidermal growth factor receptor (EGFR), human EGFRs (HER) 2, and HER4, resulting in irreversible inhibition of tyrosine kinase autophosphorylation. Studies in healthy volunteers and patients with advanced solid tumours have shown that once-daily afatinib has time-independent pharmacokinetic characteristics. Maximum plasma concentrations of afatinib are reached approximately 2–5 h after oral administration and thereafter decline, at least bi-exponentially. Food reduces total exposure to afatinib. Over the clinical dose range of 20–50 mg, afatinib exposure increases slightly more than dose proportional. Afatinib metabolism is minimal, with unchanged drug predominantly excreted in the faeces and approximately 5 % in urine. Apart from the parent drug afatinib, the major circulation species in human plasma are the covalently bound adducts to plasma protein. The effective elimination half-life is approximately 37 h, consistent with an accumulation of drug exposure by 2.5- to 3.4-fold based on area under the plasma concentration–time curve (AUC) after multiple dosing. The pharmacokinetic profile of afatinib is consistent across a range of patient populations. Age, ethnicity, smoking status and hepatic function had no influence on afatinib pharmacokinetics, while females and patients with low body weight had increased exposure to afatinib. Renal function is correlated with afatinib exposure, but, as for sex and body weight, the effect size for patients with severe renal impairment (approximately 50 % increase in AUC) is only mildly relative to the extent of unexplained interpatient variability in afatinib exposure. Afatinib has a low potential as a victim or perpetrator of drug–drug interactions, especially with cytochrome P450-modulating agents. However, concomitant treatment with potent inhibitors or inducers of the P-glycoprotein transporter can affect the pharmacokinetics of afatinib. At a dose of 50 mg, afatinib does not have proarrhythmic potential.

Br J Cancer 2017; 117:1224-1232. [PMID: 28898236 PMCID: PMC5674091 DOI: 10.1038/bjc.2017.179] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2017] [Revised: 04/26/2017] [Accepted: 05/26/2017] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND The aim was to examine the association between smoking cessation and prognosis in smoking-related cancer as it is unclear that cessation reduces mortality. METHODS In this retrospective cohort study from 1999 to 2013, we assessed the association between cessation during the first year after diagnosis and all-cause and cancer-specific mortality. RESULTS Of 2882 lung, 757 upper aero-digestive tract (UAT) and 1733 bladder cancer patients 27%, 29% and 21% of lung, UAT and bladder cancer patients quit smoking. In lung cancer patients that quit, all-cause mortality was significantly lower (HR: 0.82 (0.74-0.92), while cancer-specific mortality (HR: 0.89 (0.76-1.04) and death due to index cancer (HR: 0.90 (0.77-1.05) were non-significantly lower. In UAT cancer, all-cause mortality (HR: 0.81 (0.58-1.14), cancer-specific mortality (HR: 0.84 (0.48-1.45), and death due to index cancer (HR: 0.75 (0.42-1.34) were non-significantly lower. There was no evidence of an association between quitting and mortality in bladder cancer. The HRs were 1.02 (0.81-1.30) for all-cause, 1.23 (0.81-1.86) for cancer specific, and 1.25 (0.71-2.20) for death due to index cancer. These showed a non-significantly lower risk in sensitivity analyses. CONCLUSIONS People with lung and possibly UAT cancer who quit smoking have a lower risk of mortality than people who continue smoking.

Abstract
p66Shc is one of the three adaptor proteins encoded by the Shc1 gene, which are expressed in many organs, including the kidney. Recent studies shed new light on several key questions concerning the signaling mechanisms mediated by p66Shc. The central goal of this review article is to summarize recent findings on p66Shc and the role it plays in kidney physiology and pathology. This article provides a review of the various mechanisms whereby p66Shc has been shown to function within the kidney through a wide range of actions. The mitochondrial and cytoplasmic signaling of p66Shc, as it relates to production of reactive oxygen species (ROS) and renal pathologies, is further discussed.

Resistin as a Prooxidant Factor and Predictor of Endothelium Damage in Patients with Mild Acute Pancreatitis Exposed to Tobacco Smoke Xenobiotics. Mediators Inflamm 2017; 2017:3039765. [PMID: 29081601 PMCID: PMC5634610 DOI: 10.1155/2017/3039765] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2017] [Accepted: 07/27/2017] [Indexed: 12/17/2022] Open
Abstract
Objectives The study was aimed to assess the influence of tobacco smoke exposure on the intensity of inflammation measured by IL-6, α1-antitripsin (AAT) and α1-acid glycoprotein (AGP) concentrations, and Cd level and oxidative stress intensity measured by advanced oxidation protein product (AOPP) concentration in the blood of healthy subjects and AP patients during hospitalization. Endothelin-1 (ET-1) and resistin concentrations, markers of endothelium injury, were determined. Results An increased IL-6 concentration in healthy smokers compared to nonsmokers and AP patients compared to controls was shown. An increased AAT and AGP concentrations during hospitalization of AP patients were noted, in both smokers (AAT, AGP) and nonsmokers (AAT). In comparison to control groups, in AP patients, a 2-fold increased resistin concentration correlating with ET-1 concentration and decreased albumin concentration accompanied by increased AOPP concentration were demonstrated. AOPP concentration was higher in smokers with AP compared to nonsmokers and gradually enhanced during their hospitalization. Conclusions Tobacco smoke exposure can have a proinflammatory effect in both healthy subjects and AP patients. Increased resistin concentration in AP patients negatively correlating with albumin concentration has prooxidative effect on this protein resulting in enhanced AOPP level. Increased resistin concentration can intensify AAT and AGP production during AP.

Abstract
PURPOSE To disentangle an association between tobacco smoking, smoking habits and pharmacokinetic patterns such as plasma concentrations of risperidone (RIS), its active metabolite 9-hydroxyrisperidone (9-OH-RIS) and the active moiety, AM, (RIS+9-OH-RIS) in a naturalistic sample. METHODS Plasma concentrations, dose adjusted plasma concentrations (C/D) of RIS, 9-OH-RIS and AM in patients out of a therapeutic drug monitoring (TDM) database were compared between smokers (n=401) and non-smokers (n=292). RESULTS Daily dosage of risperidone differed significantly with smokers receiving higher doses than patients in the control group (p=0.001). No differences were detected in plasma concentrations of the active moiety, RIS and 9-OH-RIS (p=0.8 for AM, p=0.646 for RIS and p=0.538 for 9-OH-RIS). However, dose corrected concentrations (C/D) of metabolite (C/D 9-OH-RIS) and active moiety (C/D AM) differed between significantly between groups (p=0.002 and p=0.007). After stratifying smokers to a group of moderate smokers (<20cigarettes/day) (RS1, n=109) and a group of heavy smokers (≥20cigarettes/day) (RS2, n=135), the comparison between non-smokers and both groups only showed lower values of C/D for 9-OH-RIS (p=0.011) for the group of moderate smokers while other pharmacokinetic parameters did not differ. CONCLUSIONS Apart from the well-known induction of CYP1A2 activity by polycyclic aromatic hydrocarbons, smoking might exert an effect on other CYP isoenzymes as well. A possible interpretation proposes a slight inducing effect of smoking on risperidone metabolism most likely via CYP3A4.

Abstract
OBJECTIVE To identify factors predictive of admission of patients with cancer to an ICU. In addition, the study aimed to describe the characteristics and outcomes, both short-term and long-term, of patients with cancer admitted to the ICU. DESIGN Retrospective case-control study, utilizing the institution's cancer registry. SETTING Comprehensive cancer center. PATIENTS Patients with cancer. The case group consisted of patients who required ICU admission during the study period, whereas the control group consisted of patients who did not require ICU admission. INTERVENTION None. MEASUREMENTS AND MAIN RESULTS The patient characteristics and outcomes were recorded. Univariate and multivariate analyses were conducted to determine factors associated with ICU admission. The registry included 10,792 patients, and among those, 2,439 patients (22.6%) required ICU admission after a median of 10.1 months (interquartile range, 3.28-25.2). The following factors were associated with ICU admission: hematologic malignancy (odds ratio, 1.51; 95% CI, 1.26-1.81), chemotherapy (odds ratio, 1.74; 95% CI, 1.48-2.03), advanced cancer (odds ratio, 2.57; 95% CI, 1.44-4.60), and smoking (odds ratio, 1.38; 95% CI, 1.20-1.61). The most common ICU admission diagnoses were sepsis (21.5%) and respiratory insufficiency/failure (25.7%). The ICU mortality was 36.5%, whereas the 1-year and 5-year survival rates were 22.8% and 14.2%, respectively. CONCLUSION In a comprehensive cancer center, about one fourth of the patients required ICU admission. Addressing modifiable risk factors associated with ICU admission is essential to potentially reduce ICU admissions and improve long-term survival.

Abstract
There is strong evidence that cigarette smoking causes adverse outcomes in people with cancer. However, more research is needed regarding those effects and the effects of alternative tobacco products and of secondhand smoke, the effects of cessation (before diagnosis, during treatment, or during survivorship), the biologic mechanisms, and optimal strategies for tobacco dependence treatment in oncology. Fundamentally, tobacco is an important source of variation in clinical treatment trials. Nevertheless, tobacco use assessment has not been uniform in clinical trials. Progress has been impeded by a lack of consensus regarding tobacco use assessment suitable for cancer patients. The NCI-AACR Cancer Patient Tobacco Use Assessment Task Force identified priority research areas and developed recommendations for assessment items and timing of assessment in cancer research. A cognitive interview study was conducted with 30 cancer patients at the NIH Clinical Center to evaluate and improve the measurement items. The resulting Cancer Patient Tobacco Use Questionnaire (C-TUQ) includes "Core" items for minimal assessment of tobacco use at initial and follow-up time points, and an "Extension" set. Domains include the following: cigarette and other tobacco use status, intensity, and past use; use relative to cancer diagnosis and treatment; cessation approaches and history; and secondhand smoke exposure. The Task Force recommends that assessment occur at study entry and, at a minimum, at the end of protocol therapy in clinical trials. Broad adoption of the recommended measures and timing protocol, and pursuit of the recommended research priorities, will help us to achieve a clearer understanding of the significance of tobacco use and cessation for cancer patients.

Abstract
In France, in 2010, tobacco induced 81% of deaths by lung cancer corresponding to about 28,000 deaths. Continued smoking after diagnosis has a significant impact on treatment. In patients with lung cancer, the benefits of smoking cessation are present at any stage of disease. For early stages, smoking cessation decreases postoperative morbidity, reduces the risk of second cancer and improves survival. Previous to surgery, smoking cessation of at least six to eight weeks or as soon as possible is recommended in order to reduce the risk of infectious complications. Tobacco could alter the metabolism of certain chemotherapies and targeted therapies, such as tyrosine kinase inhibitors of the EGF receptor, through an interaction with P450 cytochrome. Toxicity of radiations could be lower in patients with lung cancer who did not quit smoking before treatment. For patients treated by radio-chemotherapy, overall survival seems to be better in former smokers but no difference is observed in terms of recurrence-free survival. For advanced stages, smoking cessation enhances patients' quality of life. Smoking cessation should be considered as full part of lung cancer treatment whatever the stage of disease.

Abstract
The US Food and Drug Administration (FDA) draft guidance for industry on drug interaction studies recommends, but does not mandate, that both cigarette smokers and non-smokers can be used to study drug metabolism in clinical trials, and that important results related to smoking should be included in drug labelling to guide medication usage. This study aimed to provide a comprehensive review of drugs or diseases interacting with smoking, as presented in all US drug labelling. The 62,857 drug labels deposited in the FDA Online Label Repository were searched using the keywords 'smoke', 'smoker(s)', 'smoking', 'tobacco' and 'cigarette(s)' on 19 June 2014. The resultant records were refined to include only human prescription drug labelling, for manual examination. For 188 single-active-ingredient drugs and 36 multiple-active-ingredient drugs, the labelling was found to contain smoking-related information. The pharmacokinetics of 29 and 21 single-active-ingredient drugs were affected and unaffected, respectively, by smoking. For the remaining drugs, the provided information related to smoking affecting efficacy, safety or diseases but not pharmacokinetics. Depending on the nature of specific drugs, the perturbation in pharmacokinetic parameters in smokers ranged from 13 to 500%, in comparison with non-smokers. Dosage modifications in smokers are necessary for four drugs and may be necessary for six drugs, but are unnecessary for seven drugs although the pharmacokinetic parameters of four of them are affected by smoking. Cigarette smoking is a risk factor for 16 types of diseases or adverse drug reactions. For one single-active-ingredient contraceptive drug and 10 multiple-active-ingredient contraceptive drugs, a black box warning (the FDA's strongest safety warning) is included in the labelling for increased risks of heart attacks and strokes in female smokers, and "women are strongly advised not to smoke" when using these drugs. This study presents the first comprehensive overview of cigarette smoking interacting with drugs and/or diseases, as presented in US drug labelling.

Abstract
In oncology, there is a clinical need for novel combination therapy regimens that maximize efficacy and delay resistance to individual treatment modalities. Given the role of aberrant ErbB receptor signaling in the pathogenesis of many human cancers, there is rationale for incorporating afatinib, an irreversible pan-ErbB tyrosine kinase inhibitor, into such combinations. This review focuses on: pharmacological properties of afatinib that facilitate its use in combination; preclinical rationale for the combination of afatinib with other agents; and recently completed, and ongoing, clinical trials of afatinib-based combinations across tumor types. Based on these data, we emphasize a number of areas of high unmet medical need that could benefit from afatinib-based combinations, including patients with relapsed/refractory non-small-cell lung cancer.

Abstract
With the advent of nicotine replacement therapy, the consumption of the nicotine is on the rise. Nicotine is considered to be a safer alternative of tobacco. The IARC monograph has not included nicotine as a carcinogen. However there are various studies which show otherwise. We undertook this review to specifically evaluate the effects of nicotine on the various organ systems. A computer aided search of the Medline and PubMed database was done using a combination of the keywords. All the animal and human studies investigating only the role of nicotine were included. Nicotine poses several health hazards. There is an increased risk of cardiovascular, respiratory, gastrointestinal disorders. There is decreased immune response and it also poses ill impacts on the reproductive health. It affects the cell proliferation, oxidative stress, apoptosis, DNA mutation by various mechanisms which leads to cancer. It also affects the tumor proliferation and metastasis and causes resistance to chemo and radio therapeutic agents. The use of nicotine needs regulation. The sale of nicotine should be under supervision of trained medical personnel.
