[Survival rate of bladder tumors--an analysis of 2304 patients with bladder tumors in the Tokai Urological Cancer Registry].
During the 7 years from 1980 to 1986, 2860 cases of bladder tumors were registered in the Tokai Urological Cancer Registry. Among the 2860 cases, 2304 cases were selected from the registered cases for the present study. The 5-year relative (actual) survival rates were 73.8% (61.9%) of all patients; 48.9% (42.4%) in those with malignant neoplasma of urinary bladder excluding transitional cell carcinoma; 48.8% (41/3%) in those with mixed tumor. In patients with transitional cell carcinoma, the 5-year relative (actual survival rates were 93.7% (78.8%) for G1, 87.2% (74.1%) for G2 and 47.3% (38.9%) for G3. As to staging, the 5-year survival rates were 101.9% (88.0%), 87.6% (75.3%), 57.9% (47.8%), 33.7% (28.2%) and 6.1% (5.0%) in patients with stage of Ta, T1, T2, T3 and T4, respectively. The tumors with muscle infiltration and high grade malignancy obviously deteriorated patients' survival. The 5-year relative (actual) survival rate for patients treated with TUR was 98.1% (82.2%). As to grading, the 5-year survival rates were 102.2% (86.6%) for G1, 104.3% (88.3%) for G2 and 56.9% (48.3%) for G3. The 5-year survival rates of those with Ta, T1 and T2 were 103.9% (89.7%), 96.0% (82.6) and 61.1% (49.1%), respectively. The 5-year relative (actual) survival rate for patients undergoing total cystectomy was 62.4% (52.3%). In those patients, the 5-year survival rates were 96.7% (80.9%) for G1, 63.6% (55.7%) for G2 and 55.4% (47.1%) for G3. As to staging, the 5-year survival rates were 102.3% (90.6%), 77.8% (68.2%), 56.3% (47.9%), 41.8% (34.9%) and 15.2% (13.1%) in patients with stage of Ta, T1, T2, T3 and T4, respectively. The 3 and 5-year relative (actual) survival rates in patients with advanced bladder tumors were 5.3% (4.8%) and 0.87% (0.73%), respectively.
