Clinical and prognostic studies were performed on 426 cases with tumor of the bladder, hospitalized and treated at the Department of Urology of Okayama University Hospital during 14-years from 1961 to 1974. Results are as follows:
1) As to age incidence of 426 cases, 38.3% occurs in the 7th decade. It is most frequently in this decade.
2) Male to female ratio is 5.6 with marked male predominance.
3) As to the morphologic classifications, papillary transitional cell carcinoma occupied 81%, grade II and III classified according to histological grade of A. U. A. Cancer Registry occupied 74% and the groups of stage O-B1 occupied 76%.
4) The 5-year-survival rate (observed survival rate) was presented in each initial treatment group as follows. TUC alone, 75.9%; TVC alone, 60.6%; partial cystectomy alone, 54.1%; simple total cystectomy alone, 25.6%. There is no difference between the group of combination of operative procedure with chemotherapy and/or external irradiation and the group of operation alone, except that simple total cystectomy with combination therapy (33.4%) was superior to operation alone (25.6%). This is not stastically significant, but implies that combination therapy should improve the 5-year-survival rate of the patients with bladder tumor.
