Comparing elderly and non-elderly adult cancer survivors: Differences in modifiable behaviours of smoking and alcohol cessation and physical activity.

9551 Background: In developing a cancer survivorship program at Princess Margaret Cancer Centre (Canada), cancer survivors were surveyed on modifiable behaviours: smoking/alcohol intake and physical activity. We evaluated whether special considerations should be given to elderly cancer survivors (age 65 years or higher), where few data currently exists. Methods: 616 adult cancer survivors of all disease sites were asked about their smoking, alcohol, and physical activity habits, and their attitudes and knowledge about effects of these habits on cancer outcomes. Univariate and multivariate logistic regression models evaluated the effect of age on these factors. Results: 23% were elderly; 53% female; 15% breast, 20% gastrointestinal/gynecologic, 24% hematologic, 19% thoracic/head and neck, and 13% genitourinary cancers. Median follow up was 24 months. Elderly survivors were more likely to be ever smokers (OR=1.69, 95% CI [1.12-2.53]) and ex-smokers than current (OR=4.11 [2.02-8.33]), but less likely to know...
