PATIENTS AND METHODS: Between January 1997 and July 2005, 297 men with primary nonmuscle-invasive bladder cancer were treated with transurethral resection (TUR); their smoking status before and after the diagnosis of bladder cancer was obtained by a post hoc questionnaire and interview. 'Quitters' were those who ceased smoking within a year before and 3 months after the diagnosis. Ex-smokers were those who ceased smoking more than a year before diagnosis. Several pathological and clinical variables were compared, with all statistical comparisons being two-sided. RESULTS: In all, 265 patients completed the questionnaire, including 64 non-smokers, 64 ex-smokers, 59 quitters, and 78 continued smokers. The median follow-up was 38 months. There were no significant differences in the strata of stage, grade, tumour multiplicity, intravesical therapy, or median follow-up duration between the four patient groups. The respective 3-year recurrence-free survival of continued smokers, non-smokers, ex-smokers and quitters was 45%, 57%, 62% and 70%. By multivariate analysis, high-grade, T1-stage, multiple tumours and continued smoking were significant independent predictors for a shorter recurrence-free survival. Quitters had a lower risk of recurrence than did either continued smokers or non-smokers, but had a similar risk to ex-smokers. CONCLUSION: Stopping smoking might be associated with a lower recurrence rate for patients with nonmuscle-invasive bladder cancer. ? 2007 THE AUTHORS. |
