At this point the patient was offered 3 treatment options:
- Radical cystectomy
- Bladder preservation with chemoradiation
- Active surveillance
Neoadjuvant chemotherapy with a treatment combination based on cisplatin has been shown to cause a 5-8% absolute increase in overall survival. Additional benefits of neoadjuvant chemotherapy include an increase in the PT0 rate with 20-25% of complete responders1. However, it is important to ask how reliable is the clinical T0 stage, as there is conflicting evidence on the correlation between clinical T0 and pathological T0. In a study assessing 157 patients with clinical T0, a repeat TURBT was done and demonstrated that only 35.7% had pathological T0, with almost 2/3 of patients not demonstrating T0 disease2. Even if the patients are real complete responders with T0 disease, they are still at risk of recurrence and death from bladder cancer. The stage of the disease after surgery is the main prognostic indicator of survival.
In the young patient presented at the beginning of this session, Dr. Canas believes that it is important to stay ontologically safe, thereby extending life expectancy, and try to minimize the adverse effects of surgery.
This can be achieved in several ways:
- The results have been shown to be better in high volume centers, therefore it is important these patients get operated by experienced surgeons3.
- Incorporation of the Enhanced recovery pathways (ERAS) to improve patient outcomes
- Orthotopic diversion – the rate of continent urinary diversion is very variable even at centers of excellence, but young people should be preferred candidates for continent urinary diversion, to maintain their body image.
- Discuss the possibility of preserving sexual function. This can be done with preservation of the neurovascular bundles, preservation of the seminal vesicles, and/or prostate sparing procedure. The potential candidates for this approach include young patients with normal sexual function, with organ confined disease, with no tumor in the bladder neck/prostatic urethra, and absence of prostate cancer. This has been incorporated into the European Association of Urology (EAU) guidelines which state that men motivated to preserve their sexual function, preservation of their sexual function should be offered.
