Bladder Cancer Prognosis Programme (Incorporating SELENIB Trial) [COHORT]

OBJECTIVES:

• To examine if common and potentially modifiable dietary, lifestyle, and environmental exposures affect the risk of recurrence and progression in bladder cancer.

OUTLINE: This is a multicenter study.

Detailed information will be collected about the patients' lifestyle and their exposure to risk factors associated with bladder cancer using semi-structured questionnaires. A baseline questionnaire will be administered at the time of diagnosis and will collect information about socio-demographics, environmental exposures, medical history, diet, health-related quality of life, and social support.

Further questionnaires will be administered at regular follow-up visits to capture information relating to changes in exposure. A postal questionnaire will be used to collect historical information that may require the patient to check records or consult family or friends. Patients will also be asked to keep a 1-week food, fluid, and micturition diary.
