TURを行った膀胱腫瘍症例の臨床的検討

Abstract

One hundred and eleven cases of bladder tumors were treated with transurethral resection (TUR) and transurethral electrocoagulation as the initial treatment from 1974 and 1983. Eighty nine cases were male and 22 cases were female. The average age was 60.1 years old. Of the 111 patients, 57, 33, 2, 1 and 15 patients had a tumor of Ta, T1, T2, T3a and Tx respectively. The number of grades G0, G1, G2, G3, GX cases was 1, 38, 40, 17, 12, respectively. Other than these, 2 cases of squamous cell carcinoma and 1 of adenocarcinoma were included. The actual survival rates for 5 years in Ta and T1 were 84.4 and 88.9% respectively, and the relative survival rates were 99.5 and 109.1%. TUR was recommended for superficial bladder tumor because of good prognosis. The 5-year recurrence rates for single tumors with and without prophylactic bladder instillation were 21.4 and 27.5% respectively, and those for multiple bladder tumors were 58.6 and 51.8%. There was no significant difference between the group with and without bladder instillation.
