Abstract

BACKGROUND. This study was performed to identify clinical and histologic features most significant in predicting outcome in patients with transitional cell carcinoma (TCC) of the prostate without invasive bladder carcinoma. METHODS. The histologic and clinical material from 50 patients with prostatic TCC without invasive bladder carcinoma were studied. The tumors were divided into the following locoregional categories: 1) TCC in situ (CIS) of the prostatic urethra; 2) CIS of the prostatic ducts and acini; 3) TCC with stromal invasion; 4) TCC with extraprostatic extension and/or seminal vesicle involvement; and 5) lymph node metastases. The Kaplan-Meier method was used to generate survival distributions for the locoregional categories, and comparison of survival curves was accomplished with the log rank test. RESULTS. The 5-year disease specific survival rate was 52%. The 5-year disease specific survival rates for the locoregional categories were as follows: CIS of the prostatic urethra and prostatic ducts and acini (n = 19), 100%; TCC with stromal invasion (n = 21), 45%; TCC with extraprostatic extension and seminal vesicle involvement (n = 3), 0%; and lymph node metastases (n = 7), 30%. There was a significant difference in disease specific survival when patients with CIS were compared with patients with stromal invasion, extraprostatic extension and seminal vesicle involvement, and lymph node metastases (P = 0.0001). CONCLUSIONS. This study demonstrates that patients with prostatic TCC involving prostatic stroma, extraprostatic tissues, seminal vesicles, and lymph nodes have a significantly poorer 5- year disease specific survival than patients with CIS.
