Motivating smoking cessation among patients with cancers not perceived as smoking-related: a targeted intervention

Purpose: Smoking after cancer impairs cancer treatment outcomes and prognosis, regardless of cancer type. Prior data suggest that patients with cancers other than lung or head/neck cancer had lower cessation motivation, which in turn predicted lower smoking abstinence. This study evaluated feasibility for a future efficacy trial and assessed the acceptability of brief self-help materials, targeted by cancer type, to enhance cessation motivation.

Methods: Patients had a diagnosis of skin melanoma, breast, bladder, colorectal, or gynecological cancers within ≤ 6 months, smoked ≥ 1 cigarette in the past month, and were not currently participating in a cessation program. After completing a baseline assessment, participants received the booklet corresponding to their cancer type. Follow-ups were conducted 1 week and 1 month post-intervention.

Results: Among 118 patients potentially eligible, 109 were successfully contacted and 53 patients were eligible and all consented. Among consenting patients, 92.5% completed baseline, and 90.6% received the intervention. Among patients receiving the intervention, 91.7% completed all study procedures and follow-up. At 1 month, 87.5% reported reading the booklet and 92.8% rated it as good/excellent. Motivation to quit smoking increased over time among those with lower motivation at baseline, 33.3% sought smoking cessation assistance, and 25.0% were smoke-free 1 month post-intervention.

Conclusion: This study demonstrated the feasibility and acceptability of the first intervention developed for patients with cancers not typically associated with smoking. This low-cost and easy to disseminate intervention has potential to increase motivation to quit smoking among patients with cancers not typically perceived as smoking-related.
