Abstract:Background: At present, immunotherapeutic agents such as bacillus Calmette-Guerin (BCG) and anti-tumor chemotherapeutic agents in saline are used intravesically in patients with bladder carcinoma. However, of greater significance is the possibility that the saline vehicle may itself promote carcinoma development in the bladder.
Methods:The potential promoting effects of intravesical instillation of saline were assessed in female F344 rats. The animals were divided into 3 groups, all of which received 0.05% N-b… Show more
The data suggest that intravesical instillation of BCG is more effective when no prior treatment has been attempted, and that best results may be achieved if BCG is chosen as the initial therapy for superficial bladder cancer. When pretreatment has been performed and pT1 lesions recur, however, immediate total cystectomy should be advised.
