Prognostic Variables in Patients Who Have Undergone Radical Cystectomy for Transitional Cell Carcinoma of the Bladder
Department of Urology, Kobe University School of Medicine, Kobe, Japan
Objective: To evaluate whether several clinicopathological factors could be used as prognostic predictors in patients who have undergone radical cystectomy for transitional cell carcinoma (TCC) of the bladder.
Methods: Between January 1985 and June 2000, 154 patients underwent radical cystectomy and pelvic lymphadenectomy for TCC of the bladder at a single institution. Their clinicopathological findings were analyzed based on the criteria of the Japanese Urological Association.
Results: Histopathological examination revealed that the tumor grade was 1 or 2 in 22 patients and 3 in 132 patients; the pathological stage was pT1 or less in 30 patients, pT2 in 51 patients, pT3 in 53 patients and pT4 in 20 patients. Vascular involvement and lymph node metastasis were found in 85 and 33 patients, respectively. The cause-specific 5-year survival rate was 64.2% for all patients, 74.4% for patients with grade 1 or 2 tumors, 62.9% for those with grade 3 tumors; 90.9% for those with stage pT1 or less, 77.9% for those with stage pT2, 45.0% for those with stage pT3 and 29.2% for those with stage pT4 (p < 0.001); 83.2% for patients without vascular involvement and 42.0% for those with vascular invasion (p < 0.001); and 76.5% for patients without lymph node metastasis and 22.7% for those with lymph node metastasis (p < 0.001). Multivariate analysis revealed a strong independent correlation of the pathological stage and lymph node metastasis with poor prognosis and, furthermore, the incidence of lymph node metastasis was significantly related to the increase in pathological stage.
Conclusions: In this series, the pathological stage, lymph node metastasis and vascular involvement, but not tumor grade, were significantly useful prognostic factors in patients who have undergone radical cystectomy for TCC and among them only pathological stage and lymph node metastasis could be used as independent predictors for poor prognosis.
