Optimized Treatment Strategy for HighGrade1 (HGT1) Bladder Cancer Based on Substaging: a Prospective Observational Cohort Study

Optimized Treatment Strategy for HighGradeT1 (HGT1) Bladder Cancer Based on Substaging (Depth of Lamina Propria Invasion): a Prospective Observational Cohort Study

Non-muscle invasive bladder cancer of High Grade stage T1 (HGT1), has up to 20% risk of progression to invasive disease. Because the depth of substaging seems to identify two separate groups with different progression risk (HighGradeT1a and HighGradeT1b), we design a differential treatment strategy for each group. The main hypothesis is that HighGradeT1a bladder cancer can spare a second endoscopic procedure.

Conditions

Detailed Description

Only cases of initial diagnosis of HighGradeT1 and with a complete transurethral endoscopic resection (TUR) of bladder tumor) can enter this protocol. HighGradeT1a will only receive standard BCG treatment (induction and maintenance). HighGradeT1b will undergo a second transurethral endoscopic resection (TUR) after the induction of Bacillus de Calmette-Guerin (BCG) and then continue mantenaince BCG and standard follow-up.

Cohorts and Interventions

Group / Cohort
HGT1a
HGT1a bladder cancer patients will undergo BCG induction and maintenance followed by conventional follow-up (cystoscopy and cytology at 3months and then every 6months).
HGT1b
HGT1b bladder cancer patients will undergo a 2nd TUR after BCG induction. If negative, continue with maintenance BCG followed by conventional follow-up (cystoscopy and cytology every 6months).
