[Clinical statistics of the bladder tumor--survival rates of 325 cases]

To study the relationship between clinical features and prognosis of the bladder tumor, 325 patients who were treated in our hospital were analyzed. The overall 5-year and 10-year actual survival rates were 65% and 51%. There was no statistical significance in the actual survival rate between the single and multiple tumor group. Although, there was a significant difference in tumor size, tumor growing type and the mode of treatment. The ten-year survival rates for grades 1, 2 and 3 cases were 76%, 57% and 18%, respectively. There was a significant difference between grades 1 and 3 (p less than 0.001) and grades 2 and 3 (p less than 0.001). The ten-year survival rates for stages Ta, T1, T2, T3a, T3b and T2-4 M1 were 79%, 68%, 43%, 0%, 19% and 5%, respectively. There was a significant difference between the Ta, 1 and T2-4 group (p less than 0.001).
