title: [Anti-tumor effect of intravesical instillation of mitomycin C combined with cytosine arabinoside].
abstract: The anti-tumor effect of twice a week instillation of 30 mg mitomycin C combined with 200 mg cytosine arabinoside dissolved in 30 ml saline was studied in 37 bladder tumor patients. Endoscopic or histological disappearance of the tumor was observed in 19 cases, average instillation being 16.4 times. Small (less than 1 cm in diameter), low grade, low stage and villous-surfaced tumors were more sensitive to this therapy. Further more, in the cases showing a complete response, frequency of the intravesical tumor recurrence significantly decreased compared with the cases showing no response. The clinical results of this therapy are compared mainly with those of TUR performed at our hospital, and the usefulness and clinical limitation of this kind of management in the treatment of bladder tumors are discussed.
