STAGE B (P2/3A/N0) TRANSITIONAL CELL-CARCINOMA OF BLADDER HIGHLY CURABLE BY RADICAL CYSTECTOMY

Seventy-one patients with pathologic Stage B (P2/3a/N0) transitional cell carcinoma (TCC) of the bladder underwent radical cystectomy alone without preoperative radiotherapy or perioperative chemotherapy between 1983 and 1987 and have been followed a median of fifty months. The five-year actuarial survival and disease-free survival rates were 82 percent and 77 percent, respectively, and only 13 patients (18 %) have relapsed. Histologic parameters were evaluated as to prognostic impact; none correlated with disease-free survival rates although the presence of vessel involvement portended a worse disease-free survival rate (68 % versus 80 %). During this same period, an additional 15 patients underwent radical cystectomy for pathologic Stage B disease but received adjuvant chemotherapy on the basis of vessel invasion. Their disease-free survival rate at five years was 80 percent, comparable to the disease-free survival rate for patients with vessel invasion treated by surgery alone (68 %). Although the role of systemic chemotherapy in the management of invasive bladder cancer remains under investigation, it would appear that patients with Stage B TCC are best treated with radical cystectomy alone. Continued analysis of modern surgical results grouped by current pathologic staging criteria is needed to identify patients who have a relatively low risk of relapse and thus little need for additional therapeutic intervention. These results demonstrate that Stage P2/3a/N0 TCC of the bladder is highly curable by surgery.
