Patterns of Current Cigarette Smoking, Quit Attempts, and Cessation Counseling Among Survivors of Smoking Related and Non-smoking Related Urologic Malignancies: A Nationally Representative Cross-Sectional Analysis.

INTRODUCTION AND OBJECTIVE
Cigarette smoking is the leading modifiable risk factor for several genitourinary (GU) malignancies. Although smoking cessation after GU cancer diagnosis is a critical component of survivorship, factors related to continued smoking are understudied.


METHODS
A cross-sectional analysis was conducted using data from the NHIS (2014-2018). Our primary study outcome was the prevalence and correlates of cigarette smoking among adults with history of smoking-related (kidney or bladder) urologic cancer compared with a nonsmoking-related control (prostate cancer). We used regression analyses to assess the association of having a smoking-related GU cancer history with continued cigarette smoking after diagnosis. Secondary outcomes were yearly smoking trends, quit attempts and reported receipt of smoking cessation counseling.


RESULTS
A total of 2,664 respondents reported a history of a GU cancer, representing weighted estimates of 990,820 (smoking-related GU cancer) and 2,616,596 (prostate cancer) adults. Survivors of smoking-related GU cancers had a significantly higher overall prevalence of current cigarette use (14.8% vs 8.6%, p <0.001) and also reported more frequent receipt of counseling (79.8% vs 66.2%, p=0.02) but did not attempt to quit any more often than those with prostate cancer (52.4% vs 47.2%, p=0.44). Time trends demonstrated stable and persistent cigarette use among survivors of all GU cancers. After adjustment for sociodemographic confounders, cancer type was not associated with current cigarette smoking (OR 1.23, 95% CI 0.86-1.77). However, older age and more advanced educational attainment were associated with lower odds of current cigarette smoking while single marital status was associated with higher odds.


CONCLUSIONS
In this population-based cross-sectional study of survivors of GU cancers, those with a reported smoking-related GU cancer had a higher prevalence of current cigarette smoking compared to prostate cancer, our nonsmoking related control. Those with smoking-related GU cancers reported more frequent receipt of smoking cessation counseling.
