title: [Intravesical bacillus Calmette-Guerin instillation therapy for carcinoma in situ of the urinary bladder and prediction of effects by urinary cytologic examination].
abstract: OBJECTIVE
  We investigated the effects of intravesical BCG instillations for carcinoma in situ (CIS) of the urinary bladder. And we have retrospectively analyzed the prediction of effects by fresh urinary cytologic examinations before instillation.
  
  
  METHODS
  33 patients were treated for bladder CIS (1991-1997) with a median follow-up of 30 months (range from 9 to 90 months). The patients (27 males and 6 females) ranged in age from 46 to 91 (average 71 years) and received 6 to 12 weekly BCG Tokyo 172 strain 80 mg instillations. They were divided into 3 groups based on tumor history: primary (9), secondary (15), concurrent (9). The prediction of effects were analyzed by scoring fresh urinary cytologic examinations before instillation.
  
  
  RESULTS
  22 cases (67%) were responded and they have remained free of disease for follow-up period. The statistic evaluation proved to show the significance between the effects of treatment and the sum of scoring (cellular appearance and existence of large nuclear cells).
  
  
  CONCLUSIONS
  We confirmed the effects of this treatment. The prediction of effect of this treatment seemed to be indicative by fresh urinary cytologic examinations before instillation, especially cellular appearance and existence of large nuclear cells.
