Active Surveillance vs in Office Fulguration for Low Grade Bladder Cancer Tumors

December 7, 2021 updated by: Vall Hebron Insitut Recerca

Prospective Randomized Trial in Low Grade Bladder Tumors: Active Surveillance vs Endoscopic Fulguration.

Biological behabiour of low grade bladder cancer tumors is well known. They have a very high rate of recurrences during their follow up but very low (less than 1%) risk of progression.

Until now, the gold standard of any bladder recurrence for this patients is performing an immediate transurethral ressection of the tumor.

This surgery has risk of complications and, due to the low risk of these subgroup of tumors, sometimes it becomes an overtreatment for the patients.

This is the reason why new conservative or less invasive surgeries are proposed to follow up and treat these patients.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Active surveillance
After a recurrence in patient with previous low grade bladder cancer tumor, strict follow up with cystoscopy and cytology, avoiding immediate surgery
Active Comparator: endoscopic fulguration
After a recurrence in patient with previous low grade bladder cancer tumor, fulguration under local anesthesia and sedation will be performed using a flexible cystoscope and a monopolar electrode
Procedure: Endoscopic fulguration
already included. WE will use Storz monopolar device for fulguration
Other Names:
  • Active surveillance
