[Clinical analysis of 1,000 patients with prostate cancer].
OBJECTIVE
Treatment outcomes for prostate cancer in our hospital were reported.


METHODS
We analyzed 1,009 patients with prostate cancer treated at Niigata Cancer Hospital between 1983 and 2003.


RESULTS
As for the clinical stage, 20 cases belonged to Stage I, 367 cases to Stage II, 269 cases to Stage III and 353 cases to Stage IV. The overall 5-year survival rate of the all 1,009 cases was 59.0%, comprising 78.2% for stage I, 82.0% for Stage II, 76.0% for Stage III and 30.0% for Stage IV cases. Disease-specific 5-year survival rates for Stage I, II, III and IV were 100%, 96.8%, 89.3% and 41.1% respectively. In Stage III patients, the radiotherapy (with endocrine therapy) group showed longer cause-specific survival than the endocrine therapy group (p = 0.0056).


CONCLUSIONS
Our result suggest that the radiotherapy with endocrine therapy is useful for Stage III prostate cancer.
