In our clinic, since 1985 transurethral microwave regional coagulation therapy (MRC) has been performed for patients with urinary bladder cancer as a bladder preserving procedure. The survival rate and the prognostic significance of clinical and pathological variables were investigated in 29 patients who had undergone MRC to invasive urinary bladder cancer (T2, T3NOMO). The prognosis of the patients resulted in the survival rate of 68%(G1, G2: 80%, G3: 51%) after 5 years. Six patients died of cancer. Five of these patients had G3 cancer. The death rate of patients with G3 cancer was significantly higher than those with G1 and G2 cancers. With MRC the preservation rate of the urinary bladder was 79%(23/29). In conclusion, these results indicate that we might be able to treat the invasive urinary bladder cancer without total cystectomy, applyting MRC to that of G1 and G2.
