Background: Tobacco cessation is essential to high quality oncology care. Many patients smoke when diagnosed and continue to smoke during treatment, which adversely affects treatment response and survival. Although most patients are motivated to quit, few receive effective cessation therapy. The multidisciplinary clinic (MDC), where patients, their caregivers, and key specialists coordinate care, is an ideal setting to integrate a cessation program. To assess the need for cessation services within a MDC setting, we surveyed incoming patients about their smoking status, interest in quitting, and willingness to participate in a clinic-based cessation program. Methods: The study was conducted in the Multidisciplinary Thoracic Oncology Program at Baptist Cancer Center, Memphis TN. We evaluated sociodemographic/clinical characteristics, smoking status, and tobacco dependence of consecutive new patients diagnosed with lung cancer from 2014-2019, who completed a social history questionnaire. Current smokers reported their interest in quitting and their willingness to participate in a cessation program. Chi square tests and logistic regression models were used to compare characteristics of those who would participate vs. those who would not/were unsure. Kaplan-Meier curves and multivariable Cox regression were used to evaluate the association between willingness to participate in a cessation program and overall survival, adjusted for age, sex, race, and total pack-years of smoking. Results: Of 641 patients, the average age was 69 years (range: 32-95), 47% were men, 64% white/34% black, and 17% college graduates; 90% had ever smoked, 34% currently smoked, and 24% quit smoking within the past year. Among current smokers, 60% were very interested in quitting and 37% would participate in a clinic-based cessation program. Willingness to participate was associated with greater interest in quitting (p = 0.0010) and greater overall survival (log rank p = 0.01;HR: 0.48, 95% CI: 0.24-0.95) but was not associated with any sociodemographic, clinical, or smoking-related characteristics. Conclusions: Over half (58%) of patients in a community-based MDC program were current smokers/recent quitters. Willingness to participate in a cessation program was associated with improved survival, suggesting patients with favorable prognoses are especially interested in receiving cessation support. There is considerable need for cessation services and relapse-prevention support within a coordinated, MDC lung cancer care setting.
