a systematic review and meta-analysis of e-cigarette use among cancer survivors.

Introduction:
This text provides an overview of a systematic review and meta-analysis examining the prevalence of e-cigarette use among cancer survivors, factors associated with their use, and e-cigarette use as a quit attempt. The study aims to inform healthcare providers and cancer survivors about the use of e-cigarettes in this population.

Key Points:

* The study included 23 publications from eight data sources, with a total of 138,634 cancer survivors.
* The pooled prevalence of lifetime e-cigarette use among cancer survivors was 15% (95% CI 6-27%), and current use was 3% (95% C CI 0-8%).
* among survivors who currently used traditional cigarettes, 63% (95% CI 57-69%) also used e-cigarettes.
* The reported rates of weighted lifetime e-cigarette use differed between age groups (18-44 years, up to 46.7%; 45-64, up to 27.2%; ≥65, up to 24.8%).
* Nine publications reported factors associated with lifetime e-cigarette use, including active use of traditional cigarettes, heavy drinking, poor mental health, younger age, being male, non-hispanic White, or single, having less than high school education or income ≤$25,000 USD, and living in the South regions of the US or urban areas.
* E-cigarettes were used as a quit resource by 75% of survivors reporting dual use of electronic and traditional cigarettes (95% CI 63%, 85%).

Main Message:
The study highlights the significant use of e-cigarettes among cancer survivors, particularly those who currently use traditional cigarettes. The findings suggest that healthcare providers should be aware of the high prevalence of e-cigarette use in this population and consider screening for e-cigarette use during cancer treatment and survivorship care. Further research is needed to assess the impact of e-cigarettes on long-term health outcomes in cancer survivors and to inform the development of evidence-based interventions for smoking cessation.
