Recurrence-Free Survival (RFS)
Defined as the time from study enrollment to the date of the first procedure confirming histopathological recurrence or disease progression or death from any cause. Recurrence-free survival (RFS) was censored at the date of the last follow-up visit for participants who were still alive and who had no recurrence/progression.
Time frame: Surgery to recurrence or death (Follow-up assessments were performed at 3 and 6 months after the first TUR-BT, and every 6 months thereafter, until recurrence/progression of disease, or until the end of study, up to 24 months)
Time to Recurrence
Time from enrollment to first confirmation of histopathological recurrence or disease progression. Time to recurrence was censored on date of death for patients who died, and on date of last visit for patients who were alive, without recurrence.
Time frame: Surgery to recurrence (Follow-up assessments were performed at 3 and 6 months after the first TUR-BT, and every 6 months thereafter, until recurrence/progression of disease, or until the end of study, up to 24 months)
Recurrence-Free Survival (RFS) in Subgroups
Defined as the time from study enrollment to the date of the first procedure confirming histopathological recurrence or disease progression or death from any cause. Recurrence-free survival was censored at the date of the last follow-up visit for participants who were still alive and who had no recurrence/progression.
Time frame: Surgery to recurrence or death (Follow-up assessments were performed at 3 and 6 months after the first TUR-BT, and every 6 months thereafter, until recurrence/progression of disease, or until the end of study, up to 24 months)
Tumor Recurrence Type
Tumor recurrence type (superficial, stage pTA or pT1; or muscle-invasive, stage≥pT2) was classified according to American Joint Committee on Cancer Staging Criteria for Bladder Cancer (AJCC Cancer Staging Manual, 6th edition).
