RESUMO
BACKGROUND: We designed a process to increase tobacco cessation in an academic center and its widely distributed network community sites using clinical champions to overcome referral barriers. METHODS: In 2020 a needs assessment was performed across the City of Hope Medical Center and its 32 community treatment sites. We reviewed information science strategies to choose elements for our expanded tobacco control plan, focusing on distributed leadership with tobacco cessation champions. We analyzed smoking patterns in patients with cancer before and following program implementation. We evaluated the champion experience and measured tobacco abstinence after 6 months of follow-up. RESULTS: Cancer center leadership committed to expanding tobacco control. Funding was obtained through a Cancer Center Cessation Initiative (C3I) grant. Multi-disciplinary leaders developed a comprehensive plan. Disease-focused clinics and community sites named cessation champions (a clinician and nurse) supported by certified tobacco treatment specialists. Patient, staff, clinician, and champion training/education were developed. Roles and responsibilities of the champions were defined. Implementation in pilot sites showed increased tobacco assessment from 80.8 to 96.6%, increased tobacco cessation referral by 367%, and moderate smoking abstinence in both academic (27.2%) and community sites (22.5%). 73% of champions had positive attitudes toward the program. CONCLUSION: An efficient process to expand smoking cessation in the City of Hope network was developed using implementation science strategies and cessation champions. This well-detailed implementation process may be helpful to other cancer centers, particularly those with a tertiary care cancer center and community network.

Although the harmful effects of smoking after a cancer diagnosis have been clearly demonstrated, many patients continue to smoke cigarettes during treatment and beyond. The NCCN Guidelines for Smoking Cessation emphasize the importance of smoking cessation in all patients with cancer and seek to establish evidence-based recommendations tailored to the unique needs and concerns of patients with cancer. The recommendations contained herein describe interventions for cessation of all combustible tobacco products (eg, cigarettes, cigars, hookah), including smokeless tobacco products. However, recommendations are based on studies of cigarette smoking. The NCCN Smoking Cessation Panel recommends that treatment plans for all patients with cancer who smoke include the following 3 tenets that should be done concurrently: (1) evidence-based motivational strategies and behavior therapy (counseling), which can be brief; (2) evidence-based pharmacotherapy; and (3) close follow-up with retreatment as needed.

BACKGROUND: Tobacco control is important for cancer patient health, but delivering effective low-dose CT (LDCT) screening and tobacco cessation is more difficult in underserved and patients from racial and ethnic minority groups. At City of Hope (COH), we have developed strategies to overcome barriers to the delivery of LDCT and tobacco cessation. METHODS: We performed a needs assessment. New tobacco control program services were implemented focusing on patients from racial and ethnic minority groups. Innovations included Whole Person Care with motivational counseling, placing clinician and nurse champions at points of care, training module and leadership newsletters, and a patient-centric personalized medicine Personalized Pathways to Success (PPS) program. RESULTS: Emphasis on patients from racial and ethnic minority groups was implemented by training cessation personnel and lung cancer control champions. LDCT increased. Tobacco use assessment increased and abstinence was 27.2%. The PPS pilot program achieved 47% engagement in cessation, with self-reported abstinence at 3 months of 38%, with both results slightly higher in patients from racial and ethnic minority groups than in Caucasian patients. CONCLUSIONS: Tobacco cessation barrier-focused innovations can result in increased lung cancer screening and tobacco cessation reach and effectiveness, especially among patients from racial and ethnic minority groups. The PPS program is promising as a personalized medicine patient-centric approach to cessation and lung cancer screening.
RESUMO
Rat alveolar epithelial type II cells grown on polycarbonate filters form high-resistance monolayers and concurrently acquire many phenotypic properties of type I cells. Treatment with EGF has previously been shown to increase transepithelial resistance across alveolar epithelial cell (AEC) monolayers. We investigated changes in claudin expression in primary cultured AEC during transdifferentiation to the type I cell-like phenotype (days 0, 1, and 8), and on day 5 in culture +/- EGF (10 ng/ml) from day 0 or day 4. Claudins 4 and 7 were increased, whereas claudins 3 and 5 were decreased, on later compared with earlier days in culture. Exposure to EGF led to increases in claudins 4 and 7 and decreases in claudins 3 and 5. Claudin 1 was only faintly detectable in freshly isolated type II cells and remained unchanged over time in culture and after exposure to EGF. These results suggest that increases in transepithelial resistance accompanying AEC transdifferentiation and/or EGF exposure are mediated, at least in part, by changes in the pattern of expression of specific claudin isoforms.

Beta2-Adrenergic agonists stimulate alveolar epithelial sodium (Na(+)) transport and lung fluid clearance. Alveolar type II (AT2) cells have been reported to express beta2-adrenergic receptors (beta2AR). Given the large surface area covered by alveolar type I (AT1) cells and their potential role in alveolar fluid removal, we were interested in learning if AT1 cells express beta2AR as well. Because beta2AR is potentially susceptible to desensitization by G-protein-coupled receptor kinase 2 (GRK2), we also undertook localization of GRK2. beta2AR and GRK2 expression was evaluated in whole lung, isolated alveolar epithelial cells (AECs), and AECs in primary culture, and was localized to specific AEC phenotypes by immunofluorescence techniques. beta2AR is highly expressed in AT1 cells. beta2AR mRNA increases with time in culture as AT2 cells transdifferentiate towards the AT1 cell phenotype. Immunoreactive GRK2 is seen in both AT1 and AT2 cells in similar amounts. These data suggest that both AT1 and AT2 cells may contribute to the increased alveolar Na(+) and water clearance observed after exposure to beta2 adrenergic agents. Both cell types also express GRK2, suggesting that both may undergo desensitization of beta2AR with subsequent decline in the stimulatory effects of beta2-adrenergic agonists over time.

BACKGROUND: Lung cancer screening (LCS) with low-dose-radiation (low-dose computed tomography [LDCT]) saves lives. Despite recent US Preventive Services Task Force (USPTF) draft endorsement of LCS, a minority of eligible patients get screened. Meaningful use is a set of standards for electronic health records (EHR) established by the Centers for Medicare and Medicaid Services and includes reporting of smoking status. We sought to improve rates of LCS among patients treated at our institution by identifying eligible patients using augmented smoking-related meaningful use criteria. METHODS: We launched an LCS program at our institution, a National Comprehensive Cancer Network (NCCN) cancer center, in January 2013. We developed a "tobacco screen," administered by clinic staff to all adult outpatients every 6 months and entered into the EHR. This contained smoking-related meaningful use criteria as well as a pack-year calculation and quit date if applicable. Weekly electronic reports of patients who met eligibility criteria for LCS were generated, and EHR review excluded patients who had had chest computed tomography (CT) within 12 months or who were undergoing cancer treatment. We then contacted eligible patients to review eligibility for LCS and communicated with the primary treating physician regarding the plan for LCS. RESULTS: During the first 3 months of the program, 4 patients were enrolled, 2 by physician referral and 2 by self-referral. We then began to use the tobacco screen reports and identified 418 patients potentially eligible for LCS. Over the next 7 months, we enrolled a total of 110 patients. Fifty-eight (53%) were identified from the tobacco screen, 32 (29%) were self-referred, and 20 (18%) were physician referrals. Three stage I lung cancers were detected and treated. The tobacco screen was easily implemented by clinic staff and took a median time of 2 minutes to enter for current and former smokers. Lack of response to attempts at telephone contact and objection to paying out-of-pocket costs were the most common reasons for failing to screen eligible patients. CONCLUSIONS: Use of augmented meaningful use criteria containing detailed tobacco exposure history is feasible and allows for identification of patients eligible for LCS in a medical center. Barriers to LCS include lack of insurance coverage and lack of systematic referral of patients at high risk.
