title: [Clinical assessment for prognostic factors related to recurrence and progression in superficial bladder cancer].
abstract: OBJECTIVE
  The objective of this assessment is to identify prognostic factors of recurrence and disease progression of primary superficial transitional cell carcinoma of the bladder.
  
  
  METHODS
  TUR-Bt was performed in 150 patients with initial superficial bladder cancer, of which pathological diagnosis was pTa or pT1 transitional cell carcinoma. The recurrence and progression free survival was examined. The clinicopathological factors analyzed were as follows: grade, pT, tumor size, tumor number and tumor form.
  
  
  RESULTS
  Median follow-up period was 39 months (range 3-184). The age distribution was from 25 to 98 years old with the average of 67. The patients were 122 males and 28 females. Recurrence was observed in 72 patients. The 5-year recurrence free rate for all cases were 41.6%. The factors found to be of significance for the prognosis for recurrence were tumor size (1 cm <) and tumor multiplicity (p < 0.01). Progression was seen in 15 patients; 8 invasive tumors, 2 lymph node metastases and 5 distant metastases. Twelve cases of those died of cancer. The 5-year progression free rate for all cases were 87.0%. The prognostic factors related to progression found in this study were G3, pT1 and sessile form (p < 0.01). There was no significant difference in recurrence free rate between cases with and without postoperative therapy; UFT p.o., ADM i.i. (intravesical instillation), ADM + Ara-C i.i. and PEP + 5-FU + Ara-C i.i.
  
  
  CONCLUSIONS
  Tumor size more than 1 cm and tumor multiplicity were the high risk factors about recurrence. So were G3, pT1 and sessile form about progression.
