Abstract:
A retrospective study of 46 patients with primary superficial bladder tumor was performed to identify the prognostic parameters which affect tumor recurrence. We examined 4 parameters such as stage, grade, size and number of tumor and each parameter was compared with recurrence rate respectively. The recurrence rate of stage Ta and T1 within 2 years was 33.3 % and 71% (p<0.05) and that of grade I, II and III was 40%, 60% and 100% respectively(p<0.05). Tumor recurrence was observed in 44% of patients with single tumor, 76.2% of those with multifocal tumors(p>0.05) and tumor size had no effect on tumor recurrence(p>0.06). Early recurrence rate within 1 year of grade I, II and III was 20%, 32% and 100% respectively(p< 0.01 ) but stage, number of tumor and tumor size were not correlated significantly with early recurrence rate within 1 year. A separate evaluation of the 4 parameters showed that stage and grade have a significant influence on tumor recurrence. Therefore more aggressive therapy and intensive follow-up should be considered for patients with high stage and high grade tumors.
