Patterns of Smoking Cessation Strategies and Perception of E-cigarette Harm Among Bladder Cancer Survivors.

Background: Cigarette smoking is the leading preventable cause of bladder cancer (BC). Some proponents of e-cigarettes describe their use as a risk mitigation strategy despite potential carcinogen exposure and uncertain long-term risks.

Objective: We assessed smoking cessation strategies, including e-cigarette use, and harm perception among patients with BC.

Methods: We performed a cross-sectional study on a convenience sample of patients with BC at a single institution from August 2021 - October 2022. The survey instrument was sourced from the Cancer Patient Tobacco Use Questionnaire (C-TUQ) from the American Association for Cancer Research with standardized questions on tobacco use, cessation questions, and e-cigarette harm perceptions.

Results: Of the 104 surveyed BC patients (mean age: 72 years; 27% female; 55% with muscle-invasive disease), 20% were current smokers (median pack years: 40) and 51% were former smokers (median pack years: 20). A minority (9%) had quit smoking at the time of diagnosis. Pharmacotherapy for smoking cessation included nicotine patches (25%), gum (21%), lozenges (8%), e-cigarettes (8%), and Varenicline/Bupropion (4%). Notably, 43% of patients who continued to smoke expressed willingness to switch to e-cigarettes as a cessation aid. E-cigarette users (11%) more commonly perceived e-cigarettes as non-harmful compared to former (4%) and non-smokers (4%) (P = .048), though all groups regarded e-cigarettes as equally addictive as traditional cigarettes.

Conclusions: Despite the prevalence of BC survivors who continue to smoke, a significant proportion perceive e-cigarettes as a viable and less harmful cessation aid. The infrequent use of FDA-approved pharmacotherapies underscores potential implementation gaps. These findings highlight the need for further research and targeted interventions in addressing smoking cessation among BC survivors.
