ABSTRACT
BACKGROUND: Data regarding patient education and smoking habits among bladder cancer patients are scarce. OBJECTIVE: To investigate awareness of smoking as a risk factor for bladder cancer among bladder cancer patients. DESIGN, SETTING, AND PARTICIPANTS: This is a substudy of a prospective, randomized, multicenter phase 3 trial (FinnBladder 9, NCT01675219). The data were collected at baseline and after 12 mo of follow-up between 2012 and 2020. INTERVENTION: Patients completed a comprehensive nonvalidated questionnaire on smoking in relation to bladder cancer. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The outcomes measured were patient-reported awareness of smoking as a risk factor for bladder cancer, and the effect of smoking on bladder cancer-related recurrence, progression, and death. Parametric data were compared using Student's t test and proportions using Fischer's exact test. Factors affecting baseline awareness of the effect of smoking cessation on bladder cancer were studied using logistic regression. RESULTS AND LIMITATIONS: Of the 411 patients randomized, 370 completed the baseline questionnaire and were included in the analysis. At baseline, 44% of patients were uncertain if smoking was a risk factor for bladder cancer. Patient awareness of the fact that smoking cessation reduces the risk of bladder cancer recurrence increased from 86% to 92% after 12 mo of follow-up (p = 0.038). Older patients and patients with recurrent bladder cancer had significantly less knowledge about the effect of smoking on bladder cancer recurrence, progression, and mortality. A major limitation is that the response rate was lower at the 12-mo follow-up visit than at baseline. CONCLUSIONS: Awareness of smoking as a bladder cancer risk factor is low. Older patients and patients with recurrent bladder cancer may need special attention regarding education. PATIENT SUMMARY: We looked at outcomes for smoking-related patient education on bladder cancer in a Finnish population. We conclude that older patients and patients with recurrent bladder cancer may need to be educated on this subject.

PURPOSE: To investigate the symptoms and delays in the clinical pathway of bladder cancer (BC). METHODS: This is a substudy of a prospective, randomized, multicenter phase III study (FinnBladder 9, NCT01675219) where the efficacy of photodynamic diagnosis and 6 weekly optimized mitomycin C instillations are studied in pTa bladder cancer with high risk for recurrence. The data of presenting symptoms and critical time points were prospectively collected, and the effect of factors on delays was analyzed. RESULTS: At the time of analysis, 245 patients were randomized. Analysis included 131 patients with primary bladder cancer and their complete data. Sixty-nine percent had smoking history and 67% presented with macroscopic hematuria. Median patient delay (from symptoms to health-care contact) was 7 days. The median general practice delay (from health-care contact to urology referral) was 8 days. Median time from urology referral to cystoscopy was 23 days and from cystoscopy to TUR-BT 21 days. Total time used in the clinical pathway (from symptom to TUR-BT) was 78 days. Current and former smokers had non-significantly shorter patient-related and general practice delays compared to never smokers. TUR-BT delay was significantly shorter in patients with malignant cytology (16 days) compared to patients with benign cytology (21 days, p = 0.03). CONCLUSIONS: Patient-derived delay was short and most of the delay occurred in the referral centers. The majority had macroscopic hematuria as the initial symptom. Surprisingly, current and past smokers were more prone to contact the health-care system compared to never smokers.
