[Results of BCG immunotherapy in the management of bladder tumors]

The authors reported their results of BCG immunotherapy in the treatment of the bladder cancer. between 1984-1989 60 superficial and 4 muscle infiltrative bladder tumors were treated. The results of 53 BCG treated superficial bladder cancer group were compared to control groups. The recurrence cases three-four times, the progressive cases eight-ten times were more in the control groups than it was found in the BCG group. They could not establish the value of BCG in the treatment of muscle infiltrative bladder cancer, because they had not appropriate number of patients and they could find only few articles in the literature. The authors surveied the last literature of BCG immuntherapy and verified that BCG had an important role in the treatment of the bladder cancer and searching the action of antitumor effect of BCG would add more useful information to cancer immunology.
