Abstract
Objective

To assess the characteristics and outcomes of patients with non-muscle invasive bladder cancer (NMIBC) undergoing radical cystectomy (RC) due to BCG failure.

Materials and methods

Ninety-five (11%) of the 864 patients undergoing radical cystectomy (RC) at our center from 1989 to 2002 had received prior treatment with BCG.

Of these, 62 (65.2%) underwent RC due to relapsing, high-risk NMIBC or CIS despite BCG therapy. A stage ≥ pT2 tumor was reported in the cystectomy specimen in 17 (27%) of these patients, who were considered to have been understaged.

RC was performed for clinical progression in 33 patients (34.7%). Their last transurethral resection before RC showed invasive disease.

A retrospective analysis was made of the outcomes of patients who underwent RC for BCG failure and the clinical and pathological differences between understaged patients and those with clinical progression.

Results

Five-year CSS was 90% in 45 patients with clinical and pathological NMIBC and 50.6% in 50 patients with progression to muscle-infiltrating disease (clinical progresion and understaged) (p<0,05). There were no differences in survival in patients with clinical progresion as compared to understaged patients.

Median time from tumor diagnosis to tumor progresion was 24 months (10th-90th percentile, 6–98 months). Patients with clinical progresion had significantly more T1 tumors (p=0.015) in TUR before progression and more pT3 tumors (p<0.01) in the RC specimen. Understaged patients more often had pathological pT4 stages (p<0.02).

Conclusion

In patients with high-risk NMIBCs who fail BCG therapy, RC should be performed before progression because survival is decreased when the RC specimen shows muscle-invasive disease. High-grade T1 tumors are responsible for most early clinical progressions. Patients with NMIBC may have subclinical progression, mainly within the prostate.

Resumen
Objetivos

Evaluar las características y evolución de los pacientes con tumores vesicales no músculo-infiltrantes (TVNMI) sometidos a cistectomía radical por fracaso a la terapia con bacilo de Calmette-Guérin (BCG).

Material y métodos

De 864 cistectomías radicales (CR) realizadas en nuestro centro entre 1989 y 2002, 95 (11%) se indicaron en pacientes que habían recibido tratamiento previo con BCG.

En 62 casos (65,2%) la CR se realizó por presencia de TVNMI recidivado de alto grado o carcinoma in situ, a pesar del tratamiento con BCG. En 17 de ellos (27%) la pieza de cistectomía mostró un estadio ≥ pT2. Se consideró que estos pacientes fueron infraestadiados. En 33 casos (34,7%) la CR se hizo por progresión clínica a enfermedad músculo-infiltrante (≥ T2) durante el seguimiento.

Analizamos las características y evolución de los pacientes cistectomizados por fracaso a la terapia con BCG y si existían diferencias entre los infraestadiados y los que presentaron progresión clínica durante el seguimiento.

Resultados

La supervivencia cáncer-específica a los 5 años fue del 90% en los 45 casos con estadio clínico y patológico de TVNMI, y del 50,6% en los 50 pacientes con progresión a enfermedad músculo-infiltrante (progresión clínica e infraestadiados) (p<0,05). No hubo diferencias en la supervivencia entre los pacientes infraestadiados y con progresión clínica. La mediana de tiempo entre el diagnóstico del tumor y la progresión fue de 24 meses (percentil 10–90; 6–98 meses). Los pacientes con progresión clínica presentaron de forma significativa mayor proporción de tumores T1 (p=0,015) en la RTU previa a la progresión y más pT3 (p<0,01) en pieza de CR. Los pacientes infraestadiados tuvieron más estadios patológicos pT4 (p<0,02).

Conclusiones

En TVNMI de alto riesgo que fracasan a la BCG, la CR debe realizarse antes de la progresión a tumor músculo-infiltrante. Los T1 de alto grado son responsables de la mayor parte de progresiones clínicas y tempranas. Ciertos TVNMI pueden presentar progresión subclínica a través de la próstata.
