Abstract

Between May 1990 and May 1993 we performed intravesical instillation of epirubicin hydrochloride (EPI) to 52 patients with superficical bladder tumor after transurethral resection. Indications of these instillations were classified into 3 groups. Group 1 was for carcinoma in situ (CIS) or the CIS other than the original tumor, group 2 was for multiple tumors, and group 3 was for pT1G3 tumor. Intravesical instillations of the drug were given weekly for 10 weeks and close follow-up examinations were performed routinely. Group 1 was treated for CIS, whereas group 2 and group 3 were prophylactic instillations. The disease-free rate in group 1 was 67%, and that in group 2 and group 3 was 77% at 12 months, and 42% at 24 months according to the Kaplan-Meier method. The major side effects of the instillations were bladder irritation, hematuria and pyuria. However, we experienced 5 patients with severe side effects; 2 of atrophic bladder and 3 of hemorrhagic cystitis. Although this study was conducted retrospectively, these findings suggest that intravesical instillations of EPI can be as effective as other drugs, such as mitomycin C, and doxorubicin, by adding the maintenance instillation or by elevating the drug density and shortening the instillation time.
