Background. A recent consensus conference on bladder carcinoma highlighted the need for pathologic predictors of outcome for patients with transitional cell carcinoma of the bladder. This review was undertaken to determine the pathologic features predictive of cancer‐specific survival after a radical cystectomy and urinary diversion for transitional cell carcinoma of the bladder and prostate. Methods. Between 1969 and 1990, 531 patients with transitional cell carcinoma of the bladder and prostate were treated with radical cystectomy at the Duke University Medical Center. Records and pathologic specimens were analyzed and correlated with outcome. Both univariate and multivariate analyses of the pathologic staging were performed to identify variables predictive of cancer‐specific survival. Results. Univariate analysis indicated that pathologic tumor (pT) stage, positive nodes, positive surgical margins, prostatic stromal involvement, grade, age, ureteral involvement, squamous cell carcinoma, and squamous cell differentiation in the specimen all were predictive of poor cancer‐specific survival. Carcinoma in situ (CIS) in the specimen was not an adverse prognostic indicator. Multivariate analysis demonstrated that the pT stage, nodal involvement, positive surgical margins, patient's age at surgery, and loss of histologic differentiation were predictive of poor cancer‐specific survival. CIS was found again not to have a negative influence on cancer‐specific survival. Conclusions. If any of these features are noted in the final pathologic specimen, patients should be considered for some form of additional postoperative treatment such as chemotherapy or radiation therapy in an attempt to improve their chances for cancer‐free survival. These factors will become more important in selecting which patients should be placed in developing adjuvant clinical trials.

Between January 1969 and January 1990, 531 patients underwent bilateral pelvic lymph node dissection and radical cystectomy for the management of transitional cell carcinoma of the bladder. Of these procedures 220 were performed for clinical stage Ta (31 patients), Tis (23) or T1 (166) disease, which was either high grade or recalcitrant to transurethral resection and/or intravesical chemotherapy. This subgroup of patients was studied to evaluate the outcome of recurrent or chemotherapy resistant superficial transitional cell carcinoma of the bladder after radical cystectomy. The operative mortality rate for the group was 2.3% and the overall complication rate was 20.4%. The pelvic recurrence rate was 5.9%. The 5-year cancer-specific survival rates for patients with pathological stage Ta (11), Tis (19), T0 (43) and T1 (91) disease were 88%, 100%, 80% and 76%, respectively. The 10-year cancer-specific survival rates were 75%, 92%, 66% and 62%, respectively. A total of 74 patients received preoperative radiation therapy (2,000 rad) but they had no better 5-year cancer-specific survival rates than did nonirradiated patients. Transurethral resection and/or preoperative radiation therapy resulted in a pathological status of T0 in 43 patients but this did not confer a survival advantage. Although bladder preservation is preferable, low operative mortality and pelvic recurrence rates, as well as new methods of continent urinary diversion continue to make radical cystectomy the definitive form of therapy for patients with superficial disease recalcitrant to transurethral therapy.
