Purpose:
We compared the pathological and survival outcomes of patients who underwent radical cystectomy soon after bacillus Calmette-Guérin failure with those of patients who received additional salvage intravesical chemotherapy before cystectomy for nonmuscle invasive bladder cancer. We also identified predictors of prognosis in the entire cohort.
Materials And Methods:
We retrospectively analyzed the records of 117 patients who underwent radical cystectomy for recurrent nonmuscle invasive bladder cancer at our institution from 1990 to 2012. The cohort was divided into group 1 of 61 patients treated only with bacillus Calmette-Guérin with or without interferon-α and group 2 of 56 who received at least 1 additional salvage intravesical chemotherapy after bacillus Calmette-Guérin.
Results:
Final pathology and survival outcomes did not differ significantly between the groups. Five-year overall and cancer specific survival was similar in groups 1 and 2 at 80% and 85%, respectively, at approximately equivalent followups. Median bladder retention was 1.7 years longer in group 2 (p <0.001). On multivariate Cox regression analysis delayed cystectomy in group 2 did not convey a significant hazard for all cause mortality after cystectomy (HR 1.08, p = 0.808). Only up-staging to cT1 (HR 1.88, p = 0.045), lymph node invasion (HR 2.58, p = 0.023) and prostatic urethra involvement (HR 1.95, p = 0.029) achieved significance.
Conclusions:
With appropriate selection for salvage intravesical chemotherapy patients who elect bladder sparing treatment instead of earlier radical cystectomy after bacillus Calmette-Guérin fails do not sacrifice positive pathological or oncologic outcomes while retaining bladder function for a significantly longer duration.
