Beyond the “teachable moment”: Smoking cessation during cancer treatment remains challenging despite high motivation to quit.

Abstract

e24141 Background: Continued smoking throughout cancer treatment, including surgery, is associated with treatment-related complications and a higher total symptom burden during treatment. This can lead to interruptions and delays in therapy that can compromise treatment efficacy and survival. Approximately 1 in 3 patients smoke at or around time of cancer diagnosis. Despite this “teachable moment” for smoking cessation, at least half of patients with cancer are unsuccessful in their attempts, and relapse rates for post-surgical cancer patients are high. Better understanding of quit motivation among these patients can help guide tobacco treatment interventions in the post-operative and adjuvant treatment time periods. Methods: This is an analysis of a longitudinal nationwide multicenter study of 1003 patients through the University of Rochester Cancer Center NCI Community Oncology Research Program (URCC NCORP) that assessed treatment type, treatment-related symptoms, smoking status, and motivation to quit smoking for patients with a new diagnosis of cancer. Patients supplied demographic and clinical information at enrollment with assessments at two weeks pre- adjuvant treatment, post adjuvant treatment, and 6 months. Chi-square, multinomial logistic regression, and ANOVA were used to analyze the difference between smokers and nonsmokers, and those with previous surgical treatment. Results: The majority of patients had surgery as part of their cancer treatment (n = 718, 71.6%). Of these (n = 222, 30.9%) had a diagnosis of a tobacco-associated cancer, which was associated with smoking status at pre-treatment (p < 0.05). For those with previous surgery, n = 90 (68.7%, p < 0.001) were current smokers before starting adjuvant treatment. Post-surgical patients who smoke had both higher total symptom burden ( M= 23.7 vs M= 17.0; p < 0.05) and higher symptom severity ( M =1.97 vs M= 1.42; p < 0.001) pre-adjuvant treatment and at 6 month follow up [( M =31.3 vs M= 22.2; p < 0.05);( M= 2.6 vs M= 1.8; p < 0.05)] compared to post-surgical patients who were not smokers. Motivation to quit was sustained among current smokers between the pre- and post- adjuvant treatment periods (p < 0.001), as well as for those that had previous surgery (p < 0.05). Despite motivation to quit among 64.4% of current smokers with previous surgery, 15.4% reported being able to quit by post-adjuvant treatment with 50% relapsing to smoking at 6-month follow up. Conclusions: For patients that continue to smoke after surgical treatment, cessation rates are much lower than motivation to quit with high rates of relapse. Early intervention around the time of surgery presents an ideal opportunity to optimize the “teachable moment” by providing longitudinal tobacco treatment as part of cancer care to improve treatment-related symptoms, as well as overall survival.
