Trial Outcomes & Findings for S0337, Gemcitabine After Surgery in Treating Patients With Newly Diagnosed or Recurrent Bladder Cancer (NCT NCT00445601)

NCT ID: NCT00445601

Last Updated: 2020-01-18

Results Overview

Percentage of patients who experienced a recurrence of grade 1 or 2 superficial transitional cell cancer of the bladder between the date of registration and 24 months. Disease recurrence considered to occur at date of first observation of recurrent disease subsequently confirmed by biopsy. Patients without recurrence were censored at the time of their last cystoscopy.

SECONDARY outcome

Timeframe: Up to 2 years

Population: TURBT data after patients stopped trial was not collected.

Compare whether treatment with post-TURBT intravesical instillation of gemcitabine vs placebo results in reduced long-term morbidity in patients, as defined by requirement for fewer TURBTs, courses of traditional intravesical therapies, and surveillance cystoscopies over 4 years.
