[Intravesical instillation therapy of aclacinomycin-A (ACM) for superficial bladder tumor].

Thirty-nine patients with superficial bladder cancer underwent intravesical instillation therapy of Aclacinomycin-A (ACM). Antitumor effect of ACM was evaluated in 19 patients and objective responses (CR + PR) of tumor were observed in 84.2% of these patients. Prophylactic instillation therapy of ACM was carried out on 20 patients and the results were compared with those obtained for 10 control patients who had first episode of bladder tumor and received no instillation therapy. No significant difference in the recurrent rate was observed between these two groups. The major side effect for instillation therapy with ACM was bladder irritation which appeared in 38.5% of all the patients.
