[The clinical study of 23 cases in patients with bladder cancer over 85 years old]

We treated 23 patients with bladder cancer over 85 years old. The male to female ratio was 3.6. Six cases (26%) were of low grade (G1) cancer and 16 (70%) were of high grade (G2, G3), and the other one was of unknown grade. Superficial cancer (less than or equal to pT1) was seen in 11 cases (48%), and invasive cancer (greater than or equal to pT2) was 12 cases (52%). The 3-year survival rate was 38% for all, that for superficial cancer 55%, and that for invasive cancer 0%. Fifteen cases (65%) were treated by TUR and the prognosis of invasive cases in this group was poor.
