Abstract:
OBJECTIVETo investigate the efficiency and safety of different regimens by intravesical instillation of epirubicin, a derivative of adriamycin, for the prevention of primary superficial bladder carcinoma from recurrence.
METHODSNinety patients supplemented with intravesical epirubicin instillation after operation were randomly divided into three groups: Group A--80 mg in one dose; Group B--repeated epirubicin 40 mg q wk x 4-8 sessions followed by q month to the end of the second year; or Group C--50 mg q month to the same duration. All patients were followed up for two years by observing the recurrence rates and side effects.
RESULTSThe recurrence rate of groups A, B and C at one year was 16.7%, 13.3% and 16.7%, respectively, without any significant difference observed. However, it was 50.0%, 36.7% and 36.7% at two years, at which time the recurrence rate of group A was significantly higher than those of groups B and C. The side effects rate was 23.3%, 40.0% and 33.3% for groups A, B and C, respectively. The more instillations the patients had, the more severe side effects were.
CONCLUSIONEarly postoperative single high dose intravesical instillation of epirubicin combined with repeated lower doses of the same drug every month may be an efficient and safe regimen to prevent the primary superficial bladder carcinoma from recurrence.
