Type of data Data collected Data Source
Epidemiology (1) Sociodemographic characteristics: age, sex, place of birth, educational level, marital status, household income, working situation, history of residences and of occupations.
(2) Lifestyle: history of tobacco consumption, dietary habits and physical activity.

Face to face interview
Disease management (1) Disease presentation: presence of symptoms (hematuria, pollakuria, dysuria, urgency, hydronephrosis), alteration of health status
(2) Procedures before diagnostic resection: urinary cytology, urine culture, abdominal ultrasound, urinary tract fibroscopies, imaging (scanner, MRI)
(3) Diagnosis through transurethral resection of the bladder: Hervix or Narrow-Band-Imaging (NBI) fluorescence, number and location of resected tumors, size and aspect of the largest tumor
(4) Treatment: for NMIBC intravesical instillations and cystectomy; for MIBC: chemotherapy, radiotherapy, for both NMIBC and MIBC: lymphadenectomy, urethrectomy, nephro-urethrectomy, urinary diversion, blood transfusion, any hospitalization and complications.
(5) Outcomes: locoregional and distant recurrences (dates, sites, pathology, treatments, etc.) and death (date and place)
Patient medical records
Pathology (1) Histological type and subtype
(2) Prognosis factors : for NMIBC tumor stage, grade, CIS associated, lymphovascular invasion; for MIBC, TNM stage, surgical margins, lymphovascular invasion, lymph node density
(3) Pathological review for all cases at initial diagnosis and recurrence
Patient medical records
Resource use (1) All hospitalizations: dates, type of facility, service, type of care and diagnosis-related group.
(2) Outpatient and community care : Cystoscopies, Imaging (CT, MRI, ultrasound, etc.), urine cytology, urine culture and tumor biomarkers
(3) Sick leaves
Patient medical records
Self-administered questionnaire
Quality of life (1) Generic measure: EuroQol EQ-5D-3 L questionnaire
(2) Generic measure: EORTC QLQ-C30 questionnaire
(3) Specific measures: urinary and bowel symptoms, impairment due to repeated treatments and sexual functioning.
