    Abstract:
    Superficial bladder cancer has a good prognosis compared with invasive bladder cancer. However, recurrence of the tumor is frequent and tumor stage and/or grade progress at the time of recurrence in many cases. Intravesical chemotherapy has been employed as a prophylactic method after trans-urethral resection (TUR). Although intravesical chemotherapy has been proved to be effective in delaying the first recurrence of tumor after TUR, it cannot improve the ultimate prognosis of superficial bladder cancer. Many primary, solitary, non-invasive (Ta) and grade 1 tumors do not recur or progress in stage and grade. In these cases, prophylactic intravesical chemotherapy is not essential. Bacille Calmette-Guérin (BCG) should be considered superior overall, to any chemotherapeutic agents. Comparative studies will give information about the best clinical schedule for the treatment of superficial bladder cancer.
